MVD-X type continuous vacuum microwave low-temperature dryer is specially designed for low-temperature drying of food, chemical, pharmaceutical and biological products. It has the advantages of simple operation, labor saving and real-time observation.
It includes volatile, flammable and explosive products such as ethanol and methanol, which can be dried at low temperature, and the evaporated evaporation can be recovered while drying, which is environmentally friendly and reduces environmental pollution.
MVD-x equipment can dry any water-bearing material with moisture content below 60%, and the drying temperature is controlled between 20-45 degrees for rapid dehydration, reaching a daily production capacity of 10-50 tons, which is suitable for low-temperature drying and continuous chemical production of various foods.
Microwave vacuum low-temperature drying equipment is developed to provide a new and effective low-temperature drying process for the deep processing of food, pharmaceutical, biological, chemical, new materials and agricultural by-products. Most fruits and vegetables can be dehydrated and dried at low temperature, 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 fruits, and other fruit products.
Low-temperature drying of chemical products, including various synthetic chemical powders, particles and viscous materials.
General use:
1. The initial water content of the material is below 80%.
2. The dryness is required to be within 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: ≥ -0.096Mpa.
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:

Dried fruit of microwave vacuum low temperature drying machine equipment scope of application:

Can undertake dehydration dry at low temperature in most fruits and vegetables, including banana chips, jackfruit, figs, lotus seed, red jujube and jujube, cashews, walnuts and shell walnuts, gingko shell, fructus momordicae, chickpeas, wolfberry fruit, fruit products such as low temperature and dry.

1, material in 80% of the initial water cut.

2, dry degree requirements within 1% to 20%.

3, the drying temperature within 20-120 degrees.

4, material for powder or granular, after drying to form without request.

5, conforms to the intermittent operating performance. 

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 -0.096.

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. Design service life ＞ 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.

1, low drying temperature, below 30 ℃.

2, recycled evaporation - completely recycled more than 0 ℃ can coagulate.

3, can evaporate separation material internal organic pesticide and sulfide residues - reduced to PPM level.

4, equipment work high vacuum degree - more than 0.096.

5, dry rose at the same time can get three products - sweet roses dried flowers, super, super cell SAP, rose essential oil.
