Application of Food Freeze Dryer in Tomato and Vegetable Deep Processing
The food freeze-drying machine is carried out under vacuum and low temperature. Compared with other drying methods, it can preserve the original physical and chemical and biological properties of the material to the utmost. Tomato contains a variety of vitamins and other nutrients. It has a sweet and sour taste and has always been a favorite fruit and vegetable. However, the tomato skin is thin and juicy, and it is easy to damage and rot, which brings certain difficulties to transportation and storage. The vacuum freeze-drying technology of the food freeze dryer can retain the color and flavor shape of the tomato and its original nutritional components, which solves the traditional problems in the past.
Freeze-drying process of food freeze-drying machine for deep processing of tomatoes and vegetables: structured water and a large amount of free water in tomatoes that can be frozen into ice, accounting for about 95%, and the analysis and drying time is short. The dried tomato is flaky, and the heat is transferred to the tomato in the form of radiation. Inside the tomato, the heat is transferred to the sublimation surface through the surface of the drying layer by heat conduction, and water vapor diffuses outward from the sublimation surface.
