Enzyme preparation is a kind of material with enzyme characteristics extracted from biology. Its main function is to catalyze various chemical reactions in food processing and improve food processing methods. The common enzyme preparations include papain, α - amylase, refined pectinase, β - glucosidase, etc. Enzyme preparation comes from biology, generally speaking, it is relatively safe and can be used appropriately according to production needs.

2. Water evaporation capacity: 600kgh2o / h
3. Initial moisture content: 60%
4. Final moisture after drying: 8%
5. Treatment capacity: 1060kg / h
The working principle of the rotary flash dryer for enzyme preparation is as follows
The hot air enters the stirring and crushing drying chamber from the bottom of the rotary flash dryer at an appropriate spouting speed from the inlet pipe, which has strong shearing, blowing and rotating effects on the materials. Therefore, the materials are granulated by centrifugation, shearing, collision and friction, thus enhancing the mass and heat transfer. At the bottom of the dryer, the larger and wetter particles are broken by the equipment under the action of the agitator. The particles with lower moisture content and smaller particle size are entrained by the rotating air flow and further dried in the rising process. As the gas-solid two-phase flow in rotation, the inertia of solid phase is greater than that of gas phase, and the relative velocity of solid-gas phase is relatively large, which strengthens the heat and mass transfer between the two phases, so the production intensity of rotary flash dryer is relatively high.
The characteristics of the rotary flash dryer for enzyme preparation are as follows
1. There is an inner cone structure at the bottom of the dryer, which makes the hot air flow cross-section continuously expand from bottom to top. The bottom gas velocity is large, and the upper gas velocity is small, so that the lower large particles and the upper small particles are in a good fluidization state. Moreover, the running length of the inner cantilever cone is shortened and the reliability of the inner stirring shaft is increased. The bearing is set outside the machine to avoid long-term operation in high-temperature area and prolong the service life of the bearing. Special sealing form is installed, and the material is not changed outside the machine.
2. When the wet material is crushed by the mixing teeth, part of the wet materials are thrown to the wall of the device and adhered to the wall. If it is not scraped off in time, the product quality will be affected. Therefore, a scraper is set at the top of the mixing tooth to prevent the material from overheating and denaturation.
3. The upper part of drying chamber is equipped with grading ring or grading device to effectively ensure the moisture and fineness of materials.
4. Cold air protection is set at the hot air inlet of cone bottom to prevent material from overheating and deterioration caused by contact with high temperature air.
5. High speed dispersion of materials in hot air, short drying time, especially suitable for drying heat sensitive materials.
6. Continuous operation, feed rate, hot air temperature and product fineness can be controlled within a certain range to meet the product index.
7. The drying system is closed and operated under negative pressure, with no dust leakage, environmental protection, safety and sanitation.
8. The equipment is compact in structure and occupies a small area. It integrates drying, crushing and grading. It is an optimized combination of fluidization, swirling, spouting and convective heat transfer technology. It greatly simplifies the process flow and saves equipment investment and operating costs.
