98kpa microwave vacuum low-temperature drying equipment is a new type of microwave energy application equipment combining microwave energy technology and vacuum technology
It combines a series of advantages of microwave and vacuum drying, overcomes the disadvantages of long cycle and low efficiency of conventional vacuum drying, and has the advantages of high drying output, good quality and low processing cost in the drying process of general materials
Microwave vacuum low-temperature drying equipment is a collection of electronics Vacuum science, mechanics, thermodynamics, program control and other disciplines are high-tech products, which are developed on the basis of in-depth research on the physical changes of substances in the drying process, internal and external heat and mass exchange and water migration process under vacuum conditions
Microwave vacuum drying equipment is composed of microwave generator, vacuum drying chamber, material rotating disk, vacuum system and electronic control system
In industrial production, many items cannot be dried under high temperature conditions, such as some drugs, chemicals, nutritious foods, and high-end Chinese herbal medicines such as ginseng and pilose antler
In order to ensure the quality of products, the drying treatment must be carried out at a temperature lower than 100 ℃ or room temperature
It is well known that the pressure is reduced and the boiling point of water is reduced
For example, under an atmospheric pressure (101
3 kPa), the boiling point of water is 100 ℃, At 0
073 atmospheric pressure (7
37 kPa), the boiling point of water is 40 ℃
Under vacuum conditions, heating the object can make the water inside the object evaporate without temperature rise
Because it is difficult to conduct air convection heat transfer under vacuum conditions, only by means of heat conduction to provide heat energy for materials
Conventional vacuum drying methods have slow heat conduction speed, low efficiency, and difficult temperature control
Heated materials will also produce internal and external temperature differences
Microwave heating is a kind of radiation heating, which is the direct interaction between microwave and object, so that it can be heated inside and outside at the same time, without transferring heat through convection or conduction, so it has fast heating speed, high drying efficiency and high drying quality
Edit the characteristics of this paragraph 1
Energy saving and high efficiency: conventional vacuum drying equipment, because it is very difficult to transfer heat through convection in vacuum, it can only be conducted, with slow heating speed, long drying cycle and high energy consumption
Microwave vacuum low-temperature drying equipment adopts radiation energy transfer, which is the overall heating of the medium, without other heat transfer media, avoiding the above shortcomings, so it has fast speed, high efficiency, greatly shortened drying cycle and reduced energy consumption
Compared with conventional drying technology, the work efficiency can be increased by more than four times
　　
  2
Uniform heating: because microwave heating is the simultaneous heating of materials inside and outside, the temperature difference between the inside and outside of materials is small, which will not produce the inconsistent heating inside and outside in the conventional heating, and greatly improve the drying quality
　　
  3
Easy to control: because the microwave power can be adjusted quickly and has no inertia, it is easy to control in time and facilitate the adjustment and determination of process parameters
　　
  4
The equipment is small in size and convenient for installation and maintenance
　　
  5
Good product quality: compared with conventional methods, the quality of processed products has been greatly improved
　　
  6
Microwave vacuum low-temperature drying equipment has the efficacy of disinfection and sterilization, and the products are safe and hygienic
