鱼粉生产工艺通常包括以下步骤：破碎、煮熟、挤压、干燥、研磨、筛分和包装。每个步骤在下面详细描述。
第1步：破碎鱼
In the whole fish meal production process, the first step is to shred fish if the raw materials are more than 10cm. the fresh fish are fed into a crusher after pretreatment such as cleaning and scaling. The 粉碎机 completely crushes the fish into fine particles for subsequent processing and extraction.
第2步：煮碎鱼
撕碎后，将这些原料在高温下送入煮熟机。蒸煮的目的是破坏鱼中的酶和微生物，以及变性鱼蛋白，以便更好地提取和固化。
第3步：挤压
The steamed fish material is fed into the extruder. The fish extruder machine, by means of mechanical force and temperature control, squeezes the fish material into a solid shape while allowing the water and oil to escape. The press liquor produced in this process can be used to extract fish oil.
由于含有鱼油，也可以使用鱼油分离机进行鱼油提取。
第4步：干燥
After that, it is processed by drying it in a fish meal drying machine. The purpose of drying is to remove the water from the fish pieces and turn them into dry fishmeal. By controlling the drying temperature and time, the quality and nutritional value of fishmeal can be ensured.
第5步：筛分
The dried fishmeal is graded and sieved through fishmeal sieving equipment. The purpose of sieving is to divide the fishmeal particles into different grades according to different particle sizes to meet the needs of different fields.
第6步：研磨
After screening, the 鱼粉 is fed into the mill for further fine grinding. The purpose of grinding is to make the fishmeal particles finer and more uniform, increase their solubility and digestibility, and improve the utilization rate of feed.
第7步：包装
在鱼粉生产过程中，最后一步是包装。将研磨好的鱼粉送入包装机进行包装。通常使用袋子或容器进行包装，以确保鱼粉的保存和运输安全。
