1、 Overview of Eggs
According to analysis, every hundred grams of eggs contain 12.58 grams of egg yolk, mainly composed of egg white protein and egg globulin, which contain 8 essential amino acids for the human body and are very similar in composition to human protein. The human body's absorption rate of egg yolk can reach up to 98%. Every hundred grams of eggs contain 11-15 grams of fat, mainly concentrated in the yolk and easily digested and absorbed by the human body. The yolk is rich in lecithin, steroids, vitellin, as well as calcium, phosphorus, iron, vitamin A, vitamin D, and B vitamins.
2、Application of egg yolk dryer
egg yolk dryer has the advantages of simple equipment, low cost and energy saving. As a new thin-layer drying technology, it has attracted market interest and attention. Compared with drum drying, it can significantly reduce the drying temperature, and is suitable for drying pulp materials that cannot be dried by spray and need to be dried at a lower temperature, such as strawberry pulp, banana pulp, raspberry and Must.
Due to the fact that the drying material can be heated for as little as a few minutes, exposing the components in the material to a milder heating temperature during the drying process can reduce the loss of components in the material, and the product
has good sensory quality. As an indirect drying process, the product does not come into direct contact with the heat transfer medium and there is no cross contamination; The requirements for the state of the dried materials are not high, which can concentrate juice and dry fruit and vegetable puree; Its processing water is recycled, and heat is mainly transmitted to the material through infrared radiation, improving energy utilization efficiency.
3、egg yolk 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、Advantages of egg yolk dryer
1) Using circulating hot water as a heat source to improve drying efficiency;
2) The drying conditions are mild, and the product temperature is relatively low, maintained at approximately 70 ℃;
3) Operating under low temperature and normal pressure conditions can effectively preserve the color and nutrients of the product, reducing the degree of oxidation of the product;
4) The drying time is about 3-5 minutes short;
5) Can dry most liquid materials without the need for non sugar carriers;
6) Adopting modular design, capable of continuous operation;
7) Low energy consumption.
