1、 Introduction to Pumpkin Powder
Pumpkin powder is processed from pumpkin. It contains a variety of amino acids, carotene, D vitamins, vitamin E ascorbic acid, fenugreek, Adenine, fat, glucose, pentosan and Mannitol. In addition, it also contains some organic acids, inorganic salts, Lutein, lutein, pectin and enzymes.
2、Pumpkin Powder Dryer Technical Principles ：
Wantai Pumpkin Powder Dryer is a new thin layer drying technology. Under normal pressure, 95-97 ℃ hot water is used as a thermal source. The transparent polyester film is covered on the surface of the hot water. The wet material is sprayed on the polyester film, the heat is passed to wet material through the polyester film, and the moisture of the material evaporation is eliminated by the exhaust fan, and the separation of the material from the polyester film is separated to the end point of dryness.
According to the study, when the aquatic material is placed on the surface of the polyester film, the part between the water in the material and the polyester film forms a channel that allows infrared energy to pass. The thermal energy is transmitted to the material by conduction and radiation at the same time, and the material is heated and the water is evaporated. Due to evaporation and exhaust cooling, the temperature of the material rarely exceeds 75 ° C. After the material is dried, the infrared channel will be closed. The heat can only be transmitted in a transmission. Since the polyester film is a poor conductor of heat, dry samples can avoid excessive heating.
3、Pumpkin Powder Dryer Principle：
The time of the Pumpkin Powder Dryer heating process can be short to only a few minutes. The ingredients in the materials in the drying process are exposed at a gentle heating temperature, which can reduce the component loss of the material, and the product has a good sensory quality. Spray drying, as a process of indirect drying, the product does not directly contact the heat transfer medium, and there is no cross -pollution; the state requirement of the dry material is not high; the processing water is in circulation use, and the heat is mainly transmitted to the material through infrared radiation, which improves energy utilization rate.
4、Pumpkin 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.
