What specific equipment does the complete fishmeal equipment production line include?

Fishmeal is a very important animal protein feed. my country’s fishmeal industry started late, but in recent years, with the increase in the output of high-yield and low-value fish and the development of animal husbandry, the demand for feed has surged, and the fishmeal processing industry has developed rapidly. The quality of fishmeal is closely related to the quality of feed products, and there are many factors that affect the quality of fishmeal. Among them, the processing technology of fishmeal and the selection of fishmeal equipment production lines are particularly important for the quality of fishmeal.

Fish meal processing procedure

Fishmeal processing methods are mainly divided into two types: dry method and wet method. Among them, dry method is further divided into direct drying method and dry pressing method, and wet processing method is divided into pressing method, centrifugal method, extraction method and hydrolysis method.

Because the dry processing technology requires long-term high-temperature drying of the raw materials, the oxidation of the oil is more serious, the fish meal produced is dark in color, easy to produce peculiar smell, and the protein content is not high, which affects the digestibility of the feed. The advantage is that the equipment Simple, low investment in equipment, suitable for medium and low-fat fish.

The relative wet process is currently using a more common fish meal processing technology. The characteristics of this method are that the raw materials are precooked, squeezed, separated, and then dried. The fish meal produced has better quality and higher protein content. The cost is low, and the disadvantage is that the equipment investment cost is relatively high, and the threshold for small and medium-sized enterprises is relatively high.

What machinery is used in the production process for fishmeal

Since the currently commonly used fish meal processing is a wet process, here we mainly introduce all the equipment included in the fish meal equipment production line in the wet process.

The wet processing technology mainly includes the following four methods:wet pressing process,Centrifugal Process,extraction process,Hydrolysis process

Each process has its own characteristics and applicability, but the fishmeal equipment used is nothing more than the following.

Cooking machine: The purpose of cooking is to rupture the fat cells in the fish body, coagulate the protein, and fully free the oil and water from the fish body to prepare for the subsequent pressing.

Press: separate most of the oil and moisture of the cooked material and then dry it to reduce the load of the dryer and reduce the consumption of steam.

Three-phase decanter centrifuge: By centrifuging the cooked material to separate oil, moisture and solid residue, it can replace the press to further reduce the moisture content, reduce the content of free fatty acids (FFA), reduce impurities in fish oil, and improve oil production. product to prolong the storage time of fish oil.

Fishmeal Dryer: The purpose of drying is to convert wet material into dry fishmeal. The moisture content of fish meal is generally below 12%. The use of FM low-temperature vacuum dryer of Flytime Machinery can effectively avoid high temperature oxidation of fish meal and obtain fish meal with higher content of protein.

Fishmeal cooling equipment: The purpose is to cool the fishmeal to room temperature and prevent the fishmeal from burning fat due to high temperature. A good cooler that cools fishmeal efficiently and quickly.

Vacuum concentration equipment: By concentrating and recovering the protein solution produced in the production process, the cost of fish meal production can be reduced and benefits can be increased.

Fishmeal deodorization equipment: The purpose of deodorization is to solve the odor generated during the production of fishmeal and reduce the impact on the air and the environment
