1、 Introduction to Fish Meal
1. The effective energy value of fish meal does not contain difficult to digest substances such as cellulose, and has a high content of crude fat. The effective energy value of fish meal is high, and it is easy to make high-energy feed using fish meal as raw material in production.
2. Vitamin fish meal is rich in B vitamins, especially Vitamin B12 and B2. It also contains fat soluble vitamins such as vitamin A, D and vitamin E.
3. Mineral fish meal is a good source of minerals, with high levels of calcium and phosphorus in an appropriate proportion. All phosphorus is available. Fish meal has a high selenium content, reaching over 2mg/kg. In addition, the content of iodine, zinc, iron, and selenium in fish meal is also high, and it contains an appropriate amount of arsenic.
4. Unknown growth factor Fish meal contains unknown growth promoting factors, which have not yet been purified into compounds and can stimulate animal growth and development.
2、Overview of Fish Meal Refractive window dryer：
Fish Meal Refractive window 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、Fish Meal Refractive window 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、Fish Meal Refractive window dryer Drying conditions：
The factors that restrict dryness on Fish Meal Refractive window 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.
5、Fish Meal Refractive window dryer Application advantages：
Suitable for paste, mud-shaped liquid material, especially the drying effect of thermal material.
1. Compact equipment, small volume, high production efficiency, and continuous production.
2. Drying strength, low energy consumption, and high thermal efficiency.
3. Fast drying speed, short material staying time, and high drying quality.
4. Gentle and fast drying process, retain the original product effective ingredients, and have the same quality effect as frozen and dry. The drying speed and cost are only one tenth.
