Vacuum pulsation ultrasonic drying equipment

Abstract

The invention provides vacuum pulsation ultrasonic drying equipment, which comprises a drying room, an air supply system, a pulsation system, a circulating cooling control system, a vacuum control system, an ultrasonic control system, an ultrasonic transducer and the like. According to the equipment, by coupling the cavitation effect, the mechanical effect, the heat effect and the like of ultrasonic waves with vacuum pulsation, high-efficiency rapidly drying of a material is realized. The equipment is suitable for rapidly drying foodstuffs, medicines and biological materials, is especially suitable for drying high-viscosity thermosensitive natural products, and has the advantages that the energy consumption is saved, the drying time is shortened, the physical and chemical properties of the products are kept, and the like.

Description

technical field [0001] The invention relates to a drying device, which belongs to the field of biochemical equipment. Background technique [0002] Drying is one of the main production links in chemical, food, pharmaceutical and other industries, and it is also an energy-consuming link. In current production, vacuum drying, spray drying, and freeze drying are generally used for drying. Among them, spray drying and freeze drying have problems such as expensive equipment and high production costs. However, the existing vacuum drying requires long drying time, high energy consumption, and low production efficiency. shortcoming. [0003] For heat-sensitive plant natural products, heating and drying will cause the structure of these active ingredients to break down and decompose, reduce their activity, or even lose their activity.

Problems solved by technology

In current production, vacuum drying, spray drying, and freeze drying are generally used for drying. Among them, spray drying and freeze drying have problems such as expensive equipment and high production costs. However, the existing vacuum drying requires long drying time, high energy consumption, and low production efficiency. shortcoming

[0003] For heat-sensitive plant natural products, heating and drying will cause the structure of these active ingredients to break down, decompose, reduce activity, or even lose activity, especially for heat-sensitive and high-viscosity materials, it is more difficult to dry

[0004] Freeze-drying can well maintain the biological activity of natural products, but freeze-drying needs to pre-freeze the dried target, generally at -40°C to -70°C, and the drying time is longer, generally 3- 4 days, and the amount of freeze-drying is very low each time, it is difficult to achieve large-scale production
