Cooking is a crucial part of the fishmeal production process in the fishmeal machine. It can improve the nutritional value of fishmeal and lay the foundation for the subsequent squeezing and drying process.

In this article, we will detail the reasons for cooking in the fishmeal production process and its importance in the whole production process.

Promote protein denaturation and improve digestibility

Steaming process through heating makes the protein in the fish meat denaturation, changing its molecular structure. The denatured proteins are more easily digested and absorbed, increasing the nutritional value of fishmeal.

For animal feed, this characteristic is especially important, and can effectively improve the utilization rate of feed.

Reduce moisture content and optimize dehydration effect

Fish raw materials contain a large amount of water, direct dehydration without treatment will increase energy consumption and production costs.

Cooking removes some of the moisture and lays the foundation for the subsequent pressing and dewatering steps. This not only improves dehydration efficiency, but also reduces processing time and energy use.

Remove excess fat and enhance product stability

Steaming also helps to remove excess fat from fish. Excessive fat content affects the quality and shelf life of fishmeal and can lead to oxidation and spoilage.

During the steaming process, the fat is separated from the water. It can be removed more effectively in the subsequent pressing process to ensure the stable quality of fishmeal.

Kill pathogenic microorganisms to ensure food safety

Fish raw materials may contain pathogenic microorganisms such as bacteria and parasites before processing. The high temperature in the steaming process can effectively kill these microorganisms and ensure the safety of fishmeal.

This is a key step in meeting hygiene standards when fishmeal is used as animal feed.

Improve fishmeal texture and market competitiveness

The texture of the steamed fish material is more uniform, which helps the homogeneity of crushing in the fishmeal production process, resulting in a fine texture and more stable quality of the final product.

Such fishmeal is more competitive in the market and can gain higher market recognition.

Equipment used for cooking in the fishmeal production process

Cooking in the fishmeal production process can be realized in two ways:

1. Using a cooking machine
2. Using a small compact fish meal machine

You can choose the suitable equipment according to the output. such as:

• If the capacity is 1-5t/h, the most cost-effective machine is the onboard fishmeal plant.
• If capacity of above 5t/h. the most suitable machine is an individual fish cooking machine.
