一、Summary of special spray drying engineering for bone protein:
  Bone protein is a component extracted from bone. There are many kinds of bone proteins with different functions. The domestic bone protein industry is in a rapid development stage. Animal protein is used as feed additive in feed production, while its application in food is still at a low level. Bone is rich in protein, known as "liquid meat", and the project of bone deep processing has broad prospects. Bone protein powder products in recent years to food-grade extension has an optimistic market prospects.

二、Description of special spray drying equipment for bone protein:
  The production line is composed of feeding system, medium circulation system, air heating and purification system, drying tower system, feeding system, control system and other systems. The main tower system concentrates on all the technology of spray drying engineering at present, and the charging system of the spray drying unit is formed by the combination of the first stage cyclone separator and the bag filter. The first-class cyclone is collected by high-volume and high-efficiency cyclone, and its powder yield can reach about 96%. The bag filter is an optimized equipment specially designed for protein dust removal, which can completely separate materials from the wind and settle down. The bag is a water-repellent, oil-repellent and electrostatic-proof cloth bag, and the number of filters can reach more than 500 meshes.
