10 Dicas Essenciais de Manutenção para Máquinas de Moagem de Milho e de Farinha de Trigo

 A manutenção adequada de máquinas de moagem de milho e farinha de trigo é crucial para garantir desempenho consistente, prolongar a vida útil do equipamento e maximizar a qualidade da farinha. Seguem 10 dicas práticas com base nas melhores práticas da indústria:

1. Limpeza diária das superfícies e componentes da máquina

Após cada turno, limpe as superfícies externas e internas da máquina, incluindo calhas de alimentação, câmaras de moagem e áreas de descarga. Remova grãos residuais, poeira e detritos para evitar crescimento de mofo e contaminação cruzada. Em máquinas de moagem de trigo, preste atenção especial às telas de peneira e caixas de coleta de farinha para evitar acúmulo de partículas.

2. Lubrificação regular de mancais e peças móveis

Lubrifique mancais, engrenagens e correntes diariamente para reduzir atrito e calor. Use lubrificantes recomendados pelo fabricante (ex: graxa à base de lítio para peças de alta velocidade). Para componentes como desgranadores ou moinhos de rolos, verifique os níveis de óleo semanalmente e substitua os lubrificantes a cada 3 meses para evitar desgaste.

3. Inspecionar e apertar fixadores

Vibrações durante a operação podem afrouxar parafusos, porcas e porretes. Semanalmente, inspecione todos os fixadores (ex: nos rolos de moagem, quadros de peneiradores e suportes de motor) e aperte-os para evitar desalinhamento ou danos ao equipamento. Substitua imediatamente fixadores arranhados ou corroídos.

4. Verificar e ajustar correias e polias

Monitore correias de transmissão (ex: correias em V, correias dentadas) para tensão, rachaduras ou desfiamento. As correias devem ter ~1-2cm de deflexão sob pressão moderada. Polias desalinhadas causam desgaste irregular – ajuste o alinhamento com uma régua de verificação. Substitua correias desgastadas a cada 6-12 meses, dependendo do uso.

5. Manter telas e peneiras

Telas e peneiras (ex: em planejadores, purificadores) são cruciais para separar graus de farinha. Inspecione-as diariamente para rasgos, buracos ou entupimento. Limpe as superfícies de malha com pincéis macios ou ar comprimido para manter eficiência de separação ideal. Em máquinas de moagem de farinha de trigo, substitua as peneiras quando 5% dos buracos estiverem ampliados ou danificados.

6. Calibrar sistemas de controle

Para máquinas automatizadas (ex: sistemas de controle de umidade do trigo, configurações de desgranadores de milho), calibre sensores e controles mensalmente. Verifique a precisão de adição de água, pressão de rolos de moagem e velocidade do peneirador para garantir umidade da farinha e tamanho de partícula consistentes.

7. Monitorar motor e fonte de energia

Verifique motores para ruídos anormais, superaquecimento ou vibração durante operação. Certifique-se de que conexões elétricas estão apertadas e isoladas. Para máquinas movidas a diesel, limpe filtros de ar semanalmente e drene água dos tanques de combustível para evitar danos ao motor.

8. Inspecionar guardas de segurança

Certifique-se de que todas as guardas de segurança (ex: ao redor de correias, rolos e painéis de acesso) estão intactas e firmemente fixadas. Substitua guardas rachadas ou faltantes imediatamente para prevenir acidentes. Treine operadores a nunca contornar travas de segurança durante a manutenção.

9. Armazenamento sazonal e prevenção de ferrugem

Se a máquina ficar inativa por períodos prolongados (ex: em estações baixas), limpe todas as peças, aplique inibidor de ferrugem em superfícies metálicas e armazene em local seco e ventilado. Eleve a máquina em blocos de madeira para evitar contato com pisos úmidos.

10. Manter registros detalhados de manutenção

Registre verificações diárias, reparos e substituições de peças (ex: trocas de correias, substituições de peneiras). Acompanhe tendências como falhas frequentes de mancais ou desgaste de correias para identificar problemas subjacentes (ex: desalinhamento, sobrecarga).

 

Seguindo essas dicas, operadores podem minimizar tempos de inatividade, reduzir custos de reparo e garantir produção de farinha de alta qualidade para aplicações de moagem de milho e trigo.

10 Conseils Essentiels pour l'Entretien des Machines de Mouture du Maïs et de la Farine de Blé

Un entretien approprié des machines de mouture du maïs et de la farine de blé est crucial pour garantir des performances constantes, prolonger la durée de vie de l'équipement et optimiser la qualité de la farine. Voici 10 conseils pratiques basés sur les meilleures pratiques de l'industrie :

1. Nettoyage quotidien des surfaces et composants de la machine

Après chaque service, nettoyez les surfaces extérieures et intérieures de la machine, y compris les truites d'alimentation, les chambres de broyage et les zones de décharge. Éliminez les grains résiduels, la poussière et les débris pour prévenir la croissance de moisissures et les contaminations croisées. Pour les machines de mouture du blé, accordez une attention particulière aux tamis et aux bennes de collecte de farine pour éviter l'accumulation de particules.

2. Lubrification régulière des roulements et pièces mobiles

Lubrifiez quotidiennement les roulements, engrenages et chaînes pour réduire le frottement et la chaleur. Utilisez les lubrifiants recommandés par le fabricant (ex : graisse à base de lithium pour les pièces à grande vitesse). Pour les composants tels que les débranleurs ou les moulins à rouleaux, vérifiez les niveaux d'huile chaque semaine et remplacez les lubrifiants tous les 3 mois pour prévenir l'usure.

3. Inspecter et serrer les fixations

Les vibrations pendant le fonctionnement peuvent desserrer les boulons, écrous et vis. Chaque semaine, inspectez toutes les fixations (ex : sur les rouleaux de broyage, cadres de trieurs et supports de moteur) et serrez-les pour éviter le décalage ou l'endommagement de l'équipement. Remplacez immédiatement les fixations rayées ou corrodées.

4. Vérifier et régler les courroies et poulies

Surveillez les courroies d'entraînement (ex : courroies en V, courroies dentées) pour la tension, les fissures ou l'effilochage. Les courroies doivent présenter une déviation de ~1-2cm sous pression modérée. Les poulies mal alignées causent un usure inégale : réglez l'alignement avec un outil de rectitude. Remplacez les courroies usées tous les 6-12 mois, selon l'utilisation.

5. entretenir les tamis et cribles

Les tamis et cribles (ex : dans les plansifters, purificateurs) sont essentiels pour séparer les grades de farine. Inspectez-les quotidiennement pour détecter les déchirures, trous ou blocages. Nettoyez les surfaces des maillages avec des brosses souples ou de l'air comprimé pour maintenir une efficacité de séparation optimale. Pour les machines de mouture de farine de blé, remplacez les tamis lorsque 5% des trous sont agrandis ou endommagés.

6. Calibrer les systèmes de contrôle

Pour les machines automatisées (ex : systèmes de contrôle d'humidité du blé, réglages des débranleurs de maïs), calibrez les capteurs et commandes chaque mois. Vérifiez l'exactitude de l'ajout d'eau, la pression des rouleaux de broyage et la vitesse du trieur pour garantir une teneur en humidité et une granulométrie constantes de la farine.

7. Surveiller le moteur et l'alimentation électrique

Vérifiez les moteurs pour détecter tout bruit anormal, surchauffe ou vibration pendant le fonctionnement. Assurez-vous que les connexions électriques sont serrées et isolées. Pour les machines à moteur diesel, nettoyez les filtres à air chaque semaine et videz l'eau des réservoirs de carburant pour éviter l'endommagement du moteur.

8. Inspecter les protections de sécurité

Vérifiez que toutes les protections de sécurité (ex : autour des courroies, rouleaux et panneaux d'accès) sont intactes et solidement fixées. Remplacez immédiatement les protections fissurées ou manquantes pour prévenir les accidents. Former les opérateurs à ne jamais contourner les verrous de sécurité pendant l'entretien.

9. Stockage saisonnier et prévention de la rouille

Si la machine est inactive pendant de longues périodes (ex : en saison creuse), nettoyez toutes les pièces, appliquez un inhibiteur de rouille sur les surfaces métalliques et stockez-la dans un endroit sec et ventilé. Élevez la machine sur des blocs en bois pour éviter le contact avec les sols humides.

10. Tenir des registres détaillés d'entretien

Enregistrez les vérifications quotidiennes, réparations et remplacements de pièces (ex : changements de courroies, remplacements de tamis). Suivez les tendances comme les pannes fréquentes de roulements ou l'usure des courroies pour identifier les problèmes sous-jacents (ex : décalage, surcharge).

 

En suivant ces conseils, les opérateurs peuvent minimiser les temps d'arrêt, réduire les coûts de réparation et garantir une production de farine de haute qualité pour les applications de mouture de maïs et de blé.

How does Hongdefa send engineers to Africa under severe epidemic conditions

 In the past 2019 and 2020, hongdefa and hongdefa customers have had a very difficult period.

In these 2 years, although our hongdefa has won the hearts of customers and a large number of maize flour milling machine and wheat flour processing machine orders with excellent quality.

Installing 100T maize flour mill machine 

However, after the arrival of many customers' flour milling machines, they were delayed to install, which caused our installation pressure to double.

Due to the epidemic, there are few flights, and even many flights have been suspended. The epidemic in China and the epidemic in Africa have prevented our Chinese engineers from going to Africa to complete the flour processing machines installation work.

 

Although we have done a lot of work online to guide the customer's local engineers in the maize and wheat flour milling machines installation work, such as sending all the installation drawings to the customer, doing a lot of 3D drawings and animations, videos, and even direct face-to-face video guidance installation, but still can’t completely solve this installtion problem.

For example, the installation of 300T/24H corn milling machinery, 120T/24H corn milling machinery, 100T/24H wheat flour processing machine in Zimbabwe, many sets of 100T/24H maize milling plant and wheat flour milling plant in Ethiopia, 120T/24H corn milling machinery in Swaziland, 150T/24H maize milling plant in Malawi, etc. huge and complex projects that local African engineers cannot complete independently.

             Installing 150T maize milling machine in Malawi 

The huge pressure of installation caused both hongdefa's engineers and the customer's local engineers a headache.

 

Fortunately, at the beginning of 2021, China had vaccines. We Hongdefa received the vaccine as soon as possible, and all employees were vaccinated.

At the beginning of 2021, the epidemic has also eased due to the vaccine. Flights are gradually recovering and increasing.

Our hongdefa also sent engineers to Africa to install maize and wheat flour processing machines at the first time.

However, headaches also follow.

Such as expensive air tickets and meeting all the requirements for taking a flight.

 

Expensive air tickets have put a lot of pressure on our Hongdefa customers. For the benefit of our customers, we Hongdefa decided to check the number of appointed engineers to reduce the customer's effort. The reduction in the number of engineers does not mean that the work will be reduced. On the contrary, the workload of the engineers will be greatly increased, but the decision is worthwhile.

 

Engineers need to apply for visas to Africa, and the embassy is very strict during this special period, which directly leads to the need for us to spend a lot of time to obtain visas.

Before taking a flight, engineers must do nucleic acid testing within 48 hours.

Time review is very strict, all we need to strictly enforce.

In addition, there are different requirements of various airlines.

The moment our Hongdefa engineers got on the plane, their journey had just begun.

The smooth completion of the maize and wheat flour milling machinery installation is something everyone is looking forward to.

Let our customers' machines run smoothly and put into production, is our ultimate goal.

When the engineers finished their work and was about to return home, another journey began.

We need to do nucleic acid testing locally with the help of our customers. After boarding the plane, you need to land in the transit country and do the nucleic acid test again. If the airport of the transit country does not have this capability, our engineers need to stay in the transit country for 3 days and 2 nights to wait for the test results.

The expenses in transit countries, such as accommodation, meals, testing, and transportation expenses, are all borne by Hongdefa.

At the moment the engineer landed in China, the airport bus will take the engineer directly to a specially isolated hotel for 14 days. After the quarantine, the engineer returned to his hometown and was quarantined in the hospital for 7 days before returning to his home.

All the above expenses shall be borne by hongdefa and the customer.

 

Although it is hard and difficult to go to Africa for installation and other work, everything we have done is worthwhile because we have been recognized by our customers and have given them great business help.

The success of their business is our Hongdefa happiest thing.

Meaningful activities - tree planting public welfare activities

 Spring is the season of gestating life, and all life is in the budding stage. On the afternoon of April 12th, our Shijiazhuang Hongdefa Machinery Co., Ltd. participated in a tree-planting public welfare activity with the theme of "School-enterprise cooperation to cultivate talents and discuss missions". This activity was carried out at the new campus of Hebei University of Foreign Languages in Yuanshi County. We work with the students of the school to add a little green to their new campus, our common home.

When the manager announced to all employees of the company to start the tree planting activity on April 12, the employees responded enthusiastically and positively. Many employees kept asking about the tree planting activity and the specific arrangements. I hope this special In the days, I expressed my love for the beautiful nature and support for this event. The theme of this event is "School-enterprise cooperation to cultivate talents and discuss missions." Many companies and schools contribute to the green.

 

The forest where we planted trees was named "Dream Park". Those who are in the forest are also wood; those who are wood are also lignum. High-level talents are the pillars of national construction, the soul of university survival, the origin of enterprise development, the integration of production and education, the joint construction of schools and enterprises, and the pride of the times with dreams and responsibilities.

We need to plant a large variety of small tree seedlings, and the planting area is large. At the beginning, everyone worked hard, digging holes, planting trees, and filling soil. But finally, we found that the trees that we planted were all arranged unevenly, and the small trees in the same area were all arranged unevenly. The types of saplings are also different, and everyone did not moisturize them when planting small saplings, which is not conducive to the survival of the saplings. Everyone pulled out the young sapling again.

After finding the problem, re-planning, after effective organization and arrangement, we grouped according to the previous group, and soon restarted planting trees. Some dig pits, some plant saplings, and some fill soil. Everyone is full of energy and full of energy. The meeting completed our company's tree planting task.

After everyone's efforts, a lot of trees have been planted in the originally bare open area. Looking at the neatly arranged tree saplings swaying in the spring breeze, and imagining that they will eventually thrive and cover one side after wind, frost, rain and snow, the hearts of my colleagues are happy to bloom. The small sapling that I planted will eventually become a towering tree. Finally, everyone took a group photo to commemorate, and our company employees held up their labor tools in their hands and cheered.

Generally speaking, this event was relatively successful. The main reason is that everyone has a strong sense of participation in this event. The most important thing is of course the positive attitude of colleagues, no matter how perfect the plan, no matter how rigorous the organization, without everyone’s participation, this activity is impossible to complete. The passion and vitality shown by the employees in this activity is The direct driving force for the success of this event was that there was an orderly process during the event. Everyone participated in the event with a happy mood. Only here to pay tribute to all employees of Shijiazhuang Hongdefa Machinery Co., Ltd.

For this tree planting activity, the employees felt very meaningful. This activity not only planted trees and afforested, beautified the environment, but also strengthened the communication between employees, enhanced the understanding between employees, and deepened mutual friendship. These small saplings planted together represent our company and new hope. They will grow together like the students in this school.

In short, I hope everyone can protect the trees, protect the woods, let the earth add a green, the sky will be covered with a layer of blue, and the air will become fresher!

Operation Of Wheat Flour Milling Roller Mill Machine

The same wheat flour production line, the same raw grain, and different operating skills will produce significantly different flour milling effects. As far as the grinding effect and equipment operation in wheat flour milling are concerned, good technology and equipment are the prerequisite, and the correct operation skills are the guarantee. Only in production practice, in strict accordance with the requirements of process design, comprehensive consideration and careful operation, can the overall effect of the process be brought into play.

raw material wheat

1. Grinding effect of roller mill

The main equipment in the grinding process is the mill machine. In the process design, the grinding effect of the mill machine is measured by the stripping rate and the flour extraction rate. Its size is measured by an experimental sieve, but in the process of milling The size of the material is tested by observing the crushing condition of the material after grinding, and the degree of grinding is judged by analysis. In order to find out the problems in process, equipment and operation in time.

roller mill 

1. Operating skills of the mill

Determine the best flow into the mill

Each flour path has a certain flow range. When the flow is too large, the uniformity of material crushing will decrease. If the flow is too small, it is easy to make the feeding state abnormal and the equipment work unstable. In the process of wheat flour milling, the best feed rate should be determined according to the condition of the raw grain. At the same time, it is necessary to combine the ambient temperature and humidity to detect the maximum inlet flow rate that can be reached at the time, and gradually adjust the flow to ensure that the materials are distributed to each system in the proportion required by the process design, so as to determine the best inlet flow rate.

After the optimal feed rate is determined, if the moisture, softness and hardness of the raw grain do not change much, it is not advisable to frequently adjust the feed rate to avoid disrupting the process balance and causing blockage and material drop. If the water content is uneven, the inlet flow rate should be adjusted appropriately. Generally, when the moisture deviates by 1% from the best water entering the mill, the flow of entering the mill should be reversely adjusted by about 10%. In addition, changes in seasons and climate also have a significant impact on the optimal grinding flow rate. When high temperature, high humidity, and low air pressure, the material is wet and sticky, the grinding flow rate should be appropriately reduced.

3.Final summary

The grinding effect of the mill is affected by many factors such as the nature of the incoming material, the flow rate, the feeding effect, the operating parameters of the mill, the surface parameters and processing quality of the grinding roller, the assembly quality and cleaning effect of the grinding roller, and the operation index. To stabilize the grinding effect, ensure that the quality, flow, and particle size of the incoming materials are uniform. The working parameters of the mill are reasonable and accurate, and the operation is safe and reliable. The surface parameters of the mill should be adjusted appropriately according to the material properties, flow, grinding requirements, ambient temperature, humidity, etc. To improve equipment operating skills, we must strictly follow the regulations and indicators to perform fine operations. The skin mill system must achieve the target stripping. 

While strictly controlling the stripping rate and powder extraction rate of each pass, it also controls the total stripping rate, powder extraction rate and the integrity of the bran. The heart mill system must achieve the target powder extraction, while ensuring that the bran flakes contained are not excessively broken, it also extracts the wheat flour of the corresponding quality and particle size in a targeted manner. Practice has proved that the quality of the obtained wheat flour is completely different by selectively grinding and extracting flour and non-selectively pulverizing and extracting flour. As far as wheat flour milling machine and machine operation are concerned, good craftsmanship and equipment are the prerequisite, and correct operation skills are the guarantee. Only in production practice, in strict accordance with the requirements of process design, comprehensive consideration, careful operation, more observation, more analysis, and more thinking. Only in this way can the best process effect be achieved, and the various economic and technical indicators can be guaranteed and improved, and the best effect of high quality, high extraction and high efficiency can be achieved.
