The performance of the dehydrated vegetable dryer directly affects the quality of the dried food
Dry food is a necessary measure to improve food storage and quality. The performance of dehydrated vegetable dryer can directly affect the quality and value of dry food.
Which dehydrated vegetable dryers can be used in food processing, we first classify:
The classification of dehydrated vegetable dryers usually has many forms. Each type of dryer has different classification methods according to the operation mode, structural principle, the heating mode of the material, the heat transfer principle, and the pressure of the drying chamber. According to the operation method, it can be divided into batch type and continuous type. According to the heating method, it can be divided into convection type, conduction type and radiation type. In the meantime, it can be divided into direct heating and indirect heating type. According to the structural principle, it can be divided into box tunnel type. Drum type, disc type, etc., so many classifications, how to choose non-drying technicians in practical use, how to use them, feel that there is no way to start, so it is to combine process and equipment
The vacuum freeze-dried vegetable dryer has excellent performance, which can make the moisture in the food dry directly from the solid state under the slurry and vacuum conditions, without liquid evaporation. It can preserve the original color, fragrance, taste and shape of the food to the utmost extent. The original nutrients and active substances are rarely destroyed, and the rehydration is rapid. There is no need to use preservatives. After drying, the products are popular. Type food vacuum freeze-drying machine Energy-saving food vacuum freeze-drying machine mainly includes quick freezing library for material freezing, drying chamber for sublimation dehydration and auxiliary systems such as refrigeration, vacuum and heating. The core equipment is a dry warehouse. The structure is suitable for the sublimation and dehydration of frozen materials. The freeze-dried food produced is better than the freeze-dried food produced by other methods. It is nutritious and its shape, color and taste are basically the same as fresh products. Rehydration is good.
The drum dehydration vegetable dryer is an internal heating conduction type rotary drying device. The heat transferred by the wet material in a heat conduction manner reaches the required moisture content, and the heat is transmitted from the inner wall of the cylinder to the outer wall of the cylinder, and then passes through the film. The thermal efficiency is as high as 80%-90%, the material drying period is short, only 10-15 hours, and it can be operated continuously. Widely used in the drying of liquid, ribbon, paste and viscous materials, such as meat products, dairy products, nutritious cereals, yeast, starch and so on.
Color plating to beautify the appearance of the material. According to customer demand, the product surface dress, make the product with a riot of colours rich multicolored decorations, the characteristics of the image, enhance product competitiveness and charm. Uv Color Plating can replace high-grade materials with low-grade materials. If the trophy was made of brass in the past, it is now made of plastic and plated with gold, which has a golden appearance not only reduces the cost, but also light and delicate.
UV Color Plating has become a functional coating. Such as black film, in optical instruments, solar energy and other aspects play a better role.
