Concentrated grape juice dryer

1、 Overview of Vincotto

Vincotto contains a large amount of nutrients, which has great benefits to the human body: rich sugar can be quickly absorbed by the human body, which is conducive to the growth and development of the human body; It can lower cholesterol, regulate blood lipids, and enhance immunity; Promote gastrointestinal peristalsis, facilitate digestion, and prevent constipation.

2、Concentrated grape juice dryer Technical Principles ：

Wantai Concentrated grape juice 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、 Advantages of Concentrated grape juice 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、Application of Concentrated grape juice dryer

Concentrated grape juice 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.
