Improvement of Rehydration Effect of Oolong Tea by Microwave Green-killing Dryer

Oolong tea microwave desiccant dryer is a microwave equipment for drying Oolong tea. It can be used both in one machine and in another, it can be desiccated and dried. Microwave green-killing uses the moisture of material itself to form a vapor environment. With the concussion of high-frequency microwave, the effect of green-killing is good and the material has bright color. At the same time, some moisture is lost in the green-killing process, which saves the cost of drying. The finished product is dried by microwave at one time. The dried flower has uniform dryness and green color. It does not destroy and change the nutrient composition of the material. At the same time, it has bactericidal function. The microwave dried oolong tea can completely meet the hygienic standard of food QS certification.

In the general hot air drying process, the material is heated outside, the surface is dry, and the heat is transferred inward. The direction of heat transfer is opposite to that of water diffusion, which affects the outward evaporation of water. The microwave heating is internal heating, and the high water content part warms up faster. Therefore, in the process of microwave drying, moisture migration from the inner layer to the outer layer is faster, and the drying speed is obviously faster than that of hot air drying. The application of microwave drying in Oolong tea drying has the following advantages: fast drying speed; good product quality; because the surface temperature of Oolong tea is not too high, the chlorophyll changes little, the color is green and the storage is durable, the fragrance loss is less, and the drying is even; at the same time, owing to the rapid evaporation of water, it is easy to form porous, the product has good rehydration, and the content is easy to dissolve when making tea.
