Plasma protein is the main solid component of plasma, the content is 60 ~ 80g/L, plasma protein is a variety of different functions. Domestic animal protein industry is in a stage of rapid development, animal protein as a feed additive is widely used in feed production, and the application in food is still at a low level. Pig blood is rich in protein, known as "liquid meat" reputation, pig blood deep processing projects have broad prospects. Plasma globulin powder products are used in the feed industry all the year round, and the extension to food grade in recent years has optimistic market prospects.

Spray dryers are widely used in the liquid process forming and drying industry. It is suitable for producing powder and granular solid products from solution, emulsion, suspension and paste liquid raw materials. Therefore, spray drying is a good process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet precise standards.

The air is filtered and heated into the air dispenser at the top of the dryer, and the hot air enters the drying chamber evenly in a spiral shape. The material liquid is sprayed into very fine mist droplets by the high-speed centrifugal atomizer at the top of the tower body, which can be dried into finished products in a very short time when it is in contact with the hot air. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is drained by the fan.

1、Drying speed is fast, the surface area of the material liquid is greatly increased after atomization, in the hot air stream, 95% to 98% of the water can be evaporated instantly, the drying time is only a few seconds, suitable for the drying of heat-sensitive materials.

2、The product has good uniformity, fluidity and solubility, high product purity and good quality.

3、The production process is simplified and the operation control is convenient. For the moisture content of 40-60% (special materials up to 90%) of the liquid can be dried into powder products, dry without grinding and screening, reduce the production process, improve product purity. The product particle size, loose density, moisture, in a certain range can be adjusted by changing the operating conditions, control and management are very convenient.
