Feed-grade rice protein powder is a high-protein feed additive that mainly extracts protein from rice. Its production process mainly includes the following steps:
1. **Raw material preparation**: Select rice suitable for processing into rice protein powder as raw material. The rice needs to go through pre-treatment steps such as screening and washing to remove impurities and dust.
2. **Soaking and grinding**: Soak the treated rice to make it absorb water and swell, which is convenient for the subsequent grinding process. The soaked rice is then ground into fine rice slurry by a grinder.
3. **Solid-liquid separation**: The ground rice slurry is separated by centrifugation or filtration to separate solid particles (mainly starch) from the liquid part (containing protein).
4. **Protein concentration**: The separated protein-containing liquid is concentrated, and the water content can be reduced by evaporation, reverse osmosis and other methods to increase the protein concentration.
5. **Drying**: The concentrated protein liquid is converted into a powdered product by spray drying or other forms of drying technology. This process is crucial to the storage stability of the final product.
6. **Crushing and packaging**: The dried block or flake products are further crushed into fine particles and quality tested according to standards. Qualified products will be packaged and prepared for transportation and sales.
