Preparation of Codonopsis pilosula slices with microwave vacuum low-temperature dryer honeyIssuing time:2024-08-26 13:53 Microwave vacuum low-temperature dryer, which 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 and sideline 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. 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 > 12 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. Conventional vacuum The heat conduction speed of drying method is very slow, the efficiency is low, and the temperature control is difficult. The heated material will also produce internal and external temperature difference. Microwave heating is a kind of radiation heating. It is the direct interaction between microwave and objects to make them inside and outside At the same time, it is heated without heat transfer through convection or conduction, so the heating speed is fast, the drying efficiency is high, and the drying quality is high.
