Animal protein mainly comes from meat, eggs and milk of poultry, livestock and fish. Its protein composition is mainly casein 78 ~ 85%, which can be well absorbed and utilized by adults. More importantly, animal proteins have a complete range of essential amino acids and a reasonable proportion, so they are easier to digest, absorb and utilize than general plant proteins, and their nutritional value is relatively high. In general, the protein in meat (such as fish and beef) [1] and the protein in milk have an amino acid score of 0.9 to 1.0. 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.
This machine uses a high-speed centrifugal atomizer to disperse the material into a mist, and fully contact with the hot air to complete the instant drying, forming a powder finished product drying device. The air first passes through the primary and medium effect filter, is heated by the heater and then enters the air distributor at the top of the dryer. The hot air enters the drying chamber in a spiral shape evenly, and the hot air and flow contact can be dried into finished products in a very short time. The finished product is continuously output from the bottom of the high efficiency cyclone separator, and the exhaust gas is discharged by the induced draft fan.
Protein powder production line is composed of feeding system, medium circulation system, air heating purification system, drying tower system, receiving system, control system and other systems. The main tower system integrates all the cutting-edge technologies of the current spray drying project, and the receiving system of the spray drying unit is formed by the combination of a first-stage cyclone separator and a cloth bag dust collector. The first-level cyclone is collected by high-gas and high-efficiency cyclone, and its powder collection rate can reach about 96%. The bag dust collector is an optimized equipment specially designed for protein powder dust removal, which can completely separate and settle the material from the wind. The bag is a water-repellant, oil-repellant and electrostatic cloth bag, and the filtration mesh can reach more than 500 mesh.
(1) The drying speed is very rapid, after the material liquid is sprayed, the surface area increases, and in the high temperature air flow, most of the water can be evaporated instantly, and the drying time is generally only about 5-40S.
(2) The temperature of the droplet during the drying process is not high, and the product quality is good. Temperature range for spray drying. Even if the high temperature hot air is used, the exhaust air temperature is not very high, and the material temperature does not exceed the wet bulb temperature of the surrounding hot air in the early drying stage, which is especially suitable for heat-sensitive materials.
(3) The product has good dispersion, fluidity and solubility. Since the drying process is completed in the air, the product remains in the natural ball similar to the liquid drop, with good fluidity.
(4) The production process is simplified and the operation control is convenient. Spray is usually used to deal with the wet content of 40%-90% of the solution, can be dried into powder products, most of the products do not need to be crushed and screened after drying, thus reducing the production process, simplifying the production process. The particle size, loose density and moisture of the product can be adjusted by changing the operating conditions, and the control is more convenient.
