1、 Introduction to Onion Powder
Onion powder contains Prostaglandin A, which can reduce peripheral vascular resistance and blood viscosity. It can be used to reduce blood pressure, refresh the mind, relieve stress and prevent colds. In addition, onions can also eliminate oxygen free radicals in the body, enhance metabolic ability, resist aging, and prevent osteoporosis, making them a healthy food suitable for middle-aged and elderly people.
2、Overview of Onion Powder Dryer
Onion Powder Dryer uses 95 ℃ hot water as the drying medium to perform Refractive window drying on liquid paste materials. The moisture content is dried from 90% to 5%, and the drying time is only about 5 minutes. However, conventional heat pump drying, hot air drying, and freeze-drying require more than 12 hours or even longer. Therefore, when the liquid paste material is dried, it can maintain 94% vitamin C and natural color, nutrition, flavor, and aroma. The quality of the products it produces is comparable to that of freeze-dried products, but the energy consumption is less than one-tenth of that of freeze-dried products.
3、Onion Powder Dryer system features:
1) Low energy consumption;
2) For dry liquid materials, there is no need to pre-concentrated or processing of gum for raw materials, etc.;
3) Continuous operation and production
4) Low water consumption;
5) Easy to clean;
6) Simple control and easy operation;
7) Due to the use of flexible drying and high product quality, it can maintain the original color and fragrance;
8) Operations under low temperature and normal pressure conditions, greatly reduces the oxidation of the product;
9) The product has a high loosening dump density, which reduces packaging and transportation costs.
4、Onion Powder Dryer Drying conditions:
The factors that restrict dryness on Onion Powder Dryer include air inlet temperature, exhaust temperature, air humidity, dry air volume, material liquid treatment, water evaporation, dry room diameter, dry room volume, particle diameter.
When designing the above factors, according to the characteristics of dry materials, the particle size and processing of the required product are determined, especially the diameter and volume of the dry chamber. Because they are indispensable factors, it is not possible to make too many adjustments based on this. Therefore, before the design of the Refractive window dryer, it is very necessary to select appropriate drying conditions on a small test machine.
