Banana Powder Dryer

1、 Introduction to Banana flour

Banana flour is a health food made from fresh bananas processed by advanced technology, ground into powder, pretreated, mixed, tested and packaged in a certain proportion. It has functions such as lowering blood pressure and aiding digestion.

2、Overview of Banana Powder Dryer

Banana 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、Advantages of Banana Powder 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.

4、Banana Powder Dryer Technical Principles ：

Wantai Banana 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.
