Non-metallic fruit and vegetable vacuum preservation device has been introduced

Dr. Dou Qing, a senior engineer at the Institute of Electronics, Chaoyang City, Liaoning Province, has finally developed a non-metallic fruit and vegetable vacuum preservation device, which solves the problems in the application of traditional metal vacuum equipment structures. The invention has recently been awarded a utility model patent certificate by the State Intellectual Property Office.

The material of this device is reduced by about 50% compared with metal vacuum cans, and it is lightweight, corrosion-resistant, non-toxic, and tasteless. In addition, the device integrates picking fruit baskets, fruit packing boxes, and vacuum containers into one, which reduces the mechanical damage caused by baskets falling during picking, transportation, and storage, and can be randomly disassembled and loaded.

Due to the automatic control differential pressure preservation technology, it consumes less energy and operates stably and reliably. This device is suitable for lychee, longan, mango, peach, fresh dates, cherries, and other storage of new special fruits and green peppers, pepper, beans, eggplant and other vegetables, as well as edible fungi, flowers storage and transportation preservation. It is understood that more than 10 provinces and cities across the country have pre-purchased this device, which has been applied in Shandong and other places.
