CATDOLL : CATDOLL: Soybean meal production process and methods

Soybean meal is a feed ingredient made from soybeans and is widely used in the livestock and poultry farming industry. This article will introduce the production process and methods of soybean meal to help readers better understand the process.

Raw material preparation

The main raw material of soybean meal is soybean, and high-protein varieties of soybean are usually selected as the premise of production. Before production, the soybean needs to be cleaned, impurities removed, and paraffin or steam treated to increase the soluble protein content.

Crushing and batch preparation

After washing, the soybeans are crushed in a crusher. The purpose of crushing is to break the cell structure inside the soybeans and increase the extraction rate of soluble protein. After crushing, the soybean powder is prepared in batches, and the appropriate moisture and temperature are controlled for subsequent solid-liquid separation.

Leaching

After the batch is prepared, the soy powder is mixed with water to form a slurry. This slurry enters the extractor and is extracted by hot water or steam. The temperature of the hot water can affect the extraction effect, usually between 70-75 degrees Celsius, and kept for a certain time to allow the protein to dissolve into the extract.

Solid-liquid separation and concentration and drying

The leachate after leaching and extraction enters the centrifugal degumming machine to separate the solid and liquid by centrifugation. The solid part is the soybean meal, and the liquid part is the leachate. Subsequently, the soybean meal is concentrated and dried, usually by spray drying or drum drying. The purpose of drying is to remove moisture from the soybean meal and improve its stability and storage properties.

Quality inspection and packaging

After drying, the soybean meal is inspected for quality, including protein content, particle size, moisture content, etc. After passing the quality inspection, the soybean meal is packaged and stored and transported under appropriate conditions.

Through the introduction of this article, readers can have a more comprehensive understanding of the production process and methods of soybean meal. As an important feed raw material, soybean meal plays an important role in livestock and poultry farming. I hope this article can be helpful to you.
