MVD-6kw microwave vacuum drum low-temperature expansion dryer is a new and efficient low-temperature drying equipment for the deep processing of food, pharmaceutical, biological, chemical, new materials and agricultural and sideline products.
Low temperature dehydration and drying of fruits and vegetables, including banana slices, jackfruit, figs, lotus seeds, red dates and jujube slices, cashews, walnut kernels and walnuts with shells, ginkgo with shells, siraitia grosvenorii, chickpea, lycium barbarum fruit, and other fruit products.
Low temperature drying and drying of chemical products, including various synthetic chemical powder, particles and viscous materials.
It includes volatile, flammable and explosive products such as ethanol and methanol, which can be dried at low temperature, and evaporated vapors can be recovered while drying, which is safe, environmentally friendly and reduces environmental pollution.
General use:
1. The initial water content of the material is below 80%.
2. The dryness is required to be within 0.1% - 20%.
3. The drying temperature is within 20-120 ℃.
4. The material is powder or granular, and there is no requirement on the appearance after drying.
5. It can meet the intermittent operation performance.
Common types are:
1. Drying temperature: 10-100 ℃.
2. High vacuum: ≥ -0.098-0.099Mpa.
3. Recovery of evaporation: more than 90% of the evaporated gas is effectively recovered.
4. Multi-purpose machine: can dry various materials.
5. Condensation temperature: - 20 ℃. It is comparable to the freeze-drying effect.
Other special purposes:
Microwave vacuum wall breaking:
Microwave vacuum low-temperature drying dehydration:
Microwave vacuum low-temperature sterilization:
Microwave vacuum carbonization:
Microwave vacuum removal of pesticide residues:
Microwave vacuum expansion:
Microwave vacuum desulfurization and deacidification:

1. Low drying temperature - lower than 30 ℃,
2. Recoverable evaporation ---- Recoverable condensable matter above 0 ℃.
3. It can evaporate and separate the residues of organic pesticides and sulfides inside the material -- after reduction, it can reach PPM level.
4. The vacuum degree is high when the equipment is working -- above -0.098.
5. Take dry rose as an example, three products can be obtained at the same time - sulfur free rose dry flower, super rose cell fluid and super rose essential oil.
6. The designed service life of the equipment is more than 10 years.
Under vacuum conditions, heating the object can make the water inside the object evaporate without temperature rise. Due to the difficulty of air convection and heat transfer under vacuum conditions, the only way to provide heat energy for materials is to rely on heat conduction. The conventional vacuum drying method has a slow heat transfer speed, low efficiency, and difficult temperature control. The heated material will also produce internal and external temperature difference. Microwave heating is a kind of radiation heating, which is the direct interaction between microwave and objects, so that they are heated inside and outside at the same time, without convection or conduction to transfer heat, so the heating speed is fast, the drying efficiency is high, and the drying quality is high.
