Microwave vacuum low-temperature drying equipment is developed to provide a new and efficient low-temperature drying process for the deep processing of food, pharmaceutical, biological, chemical, new materials and agricultural by-products. The flower bud and corolla can be dried at low temperature or dehydrated and dried at low temperature, and maintain a certain shape and fragrance.
Including low temperature drying of rose bud, rose crown, rose petal, Damascus, bitter rose, chrysanthemum, honeysuckle, camellia, peach, osmanthus, peony, jasmine, lavender, rosette, marigold, lily, and other flower products. At the same time, it can collect the cell fluid of roses, essential oil evaporated at low temperature and other by-products.
It can also dry and expand sliced products such as lemon and balsam pear at low temperature, including volatile, flammable and explosive products such as ethanol and methanol. It can also recover the evaporated substances during drying, which is safe, environmentally friendly and reduces environmental pollution.
Microwave vacuum low-temperature drying equipment is developed to provide a new and efficient 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.
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:
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 -0.096.
5. When drying roses, 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 ＞ 12 years.
