De quel type de travailleurs les minoteries ont-elles besoin pour travailler efficacement

 La clé pour qu’une nouvelle minoterie optimise son équipement avancé et son flux de processus est de disposer d’une équipe de travailleurs qualifiés. Même si les nouvelles recrues possèdent de vastes connaissances, elles ont néanmoins besoin d'une formation spécialisée dans l'utilisation de l'équipement d'une minoterie. Le manque de formation professionnelle aura pour conséquence que les performances des équipements et les avantages des processus ne seront pas pleinement démontrés. Pour un moulin à farine nouvellement construit, si l'équipement est mis en production dès sa mise en service et que les travailleurs qualifiés ne sont pas formés, en particulier le manque de broyeurs, de tamiseurs et de nettoyeurs de farine qualifiés, cela entraînera des démarrages et des arrêts fréquents. de l'équipement, du fonctionnement L'instabilité de la logistique et l'irrégularité du flux logistique affecteront à terme la qualité du produit et affecteront ainsi le développement du marché. Par conséquent, pour les nouvelles minoteries, il est crucial de fournir une formation professionnelle aux opérateurs occupant des postes clés.

 

Les nettoyeurs. Dans le processus de production de farine, les nettoyeurs constituent un maillon clé pour garantir le fonctionnement efficace de l’ensemble de la chaîne de production. Le processus de broyage est un système complexe et chaque maillon a un impact direct ou indirect sur la qualité du produit final. Le rôle du nettoyeur est donc crucial dans ce processus. Afin d’assurer le bon fonctionnement de la ligne de production et la stabilité de la qualité des produits, une formation professionnelle régulière et continue des agents de nettoyage est essentielle. La formation doit couvrir les principes de fonctionnement de l'équipement, les procédures de fonctionnement correctes et les connaissances en matière de maintenance quotidienne. En plus de ces connaissances de base, formez davantage les nettoyeurs sur leur capacité à diagnostiquer et à gérer les pannes d’équipement, ainsi que sur leur capacité à résoudre divers problèmes pouvant être rencontrés dans le cadre du travail réel.

Les moulins. Les ouvriers des moulins jouent le rôle central de la technologie dans les ateliers de production de farine. Non seulement ils doivent maîtriser le fonctionnement du broyeur, mais ils doivent également maîtriser l’utilisation de tous les principaux équipements de l’atelier. Le broyeur doit avoir une compréhension approfondie de l’ensemble du processus de production et être capable d’analyser les différents problèmes qui surviennent au cours du processus de production et de proposer des solutions efficaces. L’amélioration des compétences des broyeurs repose souvent sur l’accumulation d’une expérience pratique à long terme, plutôt que sur l’acquisition du jour au lendemain, même si de solides connaissances de base sont essentielles. Pendant le fonctionnement, les broyeurs doivent ajuster de manière flexible l'état de fonctionnement du broyeur en fonction des caractéristiques des matières premières, des conditions climatiques et d'autres facteurs pour garantir une qualité constante du produit. Lorsque le meunier contrôle le broyeur, la clé est d'ajuster les paramètres clés tels que le taux de décapage et le taux d'extraction de la poudre, ainsi que de surveiller des indicateurs tels que le flux de matériaux et la valeur des cendres. La formation des broyeurs est un processus systématique et continu, généralement divisé en trois étapes : premièrement, l'apprentissage théorique, qui nécessite au moins cinq mois d'apprentissage systématique ; deuxièmement, la pratique de la production, y compris la perception par l'ouïe, la vision et le toucher. équipement et changements de matériaux ; enfin, à travers des opérations pratiques, nous approfondissons notre compréhension de l'effet de broyage et de l'effet de criblage.

Les tamiseurs. Les ouvriers tamiseurs jouent un rôle essentiel dans la production de farine, et leur niveau technique est juste derrière celui des ouvriers meuniers. Un travailleur qualifié en matière de criblage de poudre doit avoir une compréhension approfondie du chemin de la poudre et du chemin de criblage, et être capable d'acquérir une compréhension tridimensionnelle de ces connaissances dans son esprit, ainsi qu'une compréhension approfondie du flux de matériaux et du processus de traitement. dans chaque lien. Ils doivent non seulement avoir une compréhension approfondie des fonctions et des principes des grilles de tamis, mais également être capables d'utiliser ces connaissances de manière flexible pour découvrir et corriger les erreurs de placement des grilles de tamis, et effectuer des ajustements en fonction des besoins de production pour obtenir le meilleur effet de poudre de tamisage. . Les agents de criblage de poudre doivent recevoir une formation de base sur les routes de poudre et les routes de criblage avant de prendre officiellement leurs fonctions. Cette formation comprend non seulement l'apprentissage de connaissances théoriques, mais également le développement de compétences pratiques. Ce n'est qu'après avoir pleinement maîtrisé ces connaissances de base que les opérateurs de criblage de poudre peuvent entrer dans l'atelier pour des opérations réelles et approfondir davantage leur compréhension et leur maîtrise du processus de criblage de poudre par la pratique.

 

Les purificateurs. Les nettoyeurs de farine sont des professionnels chargés de faire fonctionner les nettoyeurs de farine. Ils jouent principalement un rôle dans le processus de nettoyage de la farine lors de la transformation de la farine. La fonction du purificateur de farine est de purifier davantage les matières grossières et le noyau de blé, et en séparant les impuretés telles que les résidus de blé et le son cassé, de fournir des matières premières plus pures pour le système de broyage à cœur ultérieur, garantissant ainsi la qualité et le rendement de la farine. Le travail quotidien d'un nettoyeur de poussière comprend une surveillance étroite du fonctionnement du nettoyeur de poussière, en particulier des brosses de nettoyage dans la zone d'alimentation. Ils doivent garantir que la puissance d'aspiration de la chambre d'aspiration est uniformément répartie et que la force du vent est ajustée de manière appropriée pour garantir que le matériau peut se répandre uniformément sur la surface du tamis et former un état flottant. De cette façon, les impuretés légères telles que les petites particules de gluten peuvent être aspirées par le conduit d'air, tandis que le matériau situé à l'orifice de décharge doit maintenir une pureté élevée. Selon l'état réel du matériau, le nettoyeur en poudre doit également distribuer raisonnablement les matériaux criblés au système correspondant afin d'optimiser l'ensemble du processus de nettoyage en poudre. Afin d'être qualifiés pour cette responsabilité, les nettoyeurs de poudre doivent recevoir une formation professionnelle avant de prendre officiellement leurs fonctions, et apprendre les principes de fonctionnement, les connaissances en matière d'entretien et les compétences de manipulation du matériel du nettoyeur de poudre pour garantir qu'ils peuvent utiliser et ajuster habilement l'équipement. le processus.

 

Les opérateurs PLC Les opérateurs de systèmes de contrôle automatisés, en particulier les automates programmables (PLC), jouent un rôle clé dans l'automatisation de la production de farine. Le PLC peut contrôler automatiquement le démarrage et l'arrêt de l'équipement en fonction des besoins du processus de production de farine. Il peut également contrôler avec précision le démarrage et l'arrêt d'un équipement mono-machine et surveiller l'état de fonctionnement de l'équipement en temps réel. Lorsque des problèmes tels qu'un blocage de matériau sont détectés, le système PLC peut émettre une alarme à temps et émettre automatiquement une commande d'arrêt pour empêcher l'équipement affectant la qualité du produit de continuer à fonctionner et garantir que les opérateurs puissent effectuer rapidement des réparations. Les opérateurs d'automates programmables doivent posséder des connaissances et des compétences de base en matière d'exploitation informatique, notamment une familiarité avec les opérations informatiques de base et une certaine base théorique informatique. Grâce à une formation professionnelle, ils doivent être capables d'effectuer habilement l'exploitation et la maintenance quotidiennes des automates et de gérer les défauts simples courants des systèmes automates. Une telle formation améliore non seulement le niveau technique des opérateurs, mais garantit également la stabilité et l'efficacité du processus de production.

 

Pour résumer, les travailleurs recrutés par les nouvelles moulins à farine doivent subir une formation professionnelle avant de travailler.
