Intelligentized static microwave vacuum drying machine

Abstract

The invention provides an intelligent static microwave vacuum drier which is used for quickly drying plant extracts, foodstuff, subsidiary agricultural products, chemical products and so on under low temperature to get high quality dry products. In order to solve the defects of the prior art, namely, low dry quality, high energy dissipation, low output, long cycle, large investment, high cost, unstable operation of equipment and so on, the intelligent static microwave vacuum drier can dry materials quickly and uniformly at low temperature in static state. During the drying process, the power, the temperature and the time are intelligently and automatically controlled according to the varieties and the dryness of materials, thus getting high-quality dry materials with the moisture error less than positive or negative 2 percent. The equipment runs stably and dries uniformly; little energy is consumed; little money is invested on equipment without environmental pollution. By comparing the intelligent static microwave vacuum drier with the traditional electrothermal vacuum drying and electrothermal cabinet drying, the energy is saved by more than 90 percent; by comparing the intelligent static microwave vacuum drier with the spray drying, the energy is saved by more than 80 percent; by comparing the intelligent static microwave vacuum drier with the basket microwave vacuum drier, the energy is saved by more than 10 percent. The dry quality is better than the quality of other dry modes.

Description

technical field [0001] The invention relates to an intelligent static microwave vacuum dryer, which can quickly, uniformly, and low-temperature dry plant extracts, food, agricultural and sideline products, chemical products, etc. placed statically in the equipment to obtain high-quality dried items. Background technique [0002] At present, items that require low-temperature drying, such as plant extracts, food, and agricultural by-products, mainly use oven drying, ordinary vacuum drying, spray drying, and rotary microwave vacuum drying methods. Oven drying, ordinary vacuum drying, and spray drying methods are all traditional heating methods. The heat is carried out through conduction, radiation, and convection. The drying temperature generally exceeds 80°C. It takes a long time to dry in an electric oven. With ordinary vacuum drying equipment, heat transfer is very difficult, especially when the moisture on the surface of the item is reduced and a solid shell is formed, but...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of the existing technology such as low drying quality, high energy consumption, low output, long cycle, large investment, high cost, and unstable equipment operation, we have developed an intelligent static microwave vacuum drying equipment, which can make The material is dried at low temperature, quickly and evenly in a static state. During the drying process, the power, temperature and time are automatically controlled intelligently according to the material type, water content and weight, so as to obtain high-quality dry materials. This equipment has high operating stability. , Good drying uniformity, low energy consumption, small equipment investment, no environmental pollution
