High-voltage electric field and hot air combined drying device

Abstract

The invention discloses a high-voltage electric field and hot air combined drying device. The high-voltage electric field and hot air combined drying device comprises a box body, a high-voltage electric field drying system, a hot air circulation drying system and a monitoring control system, wherein the high-voltage electric field drying system, the hot air circulation drying system and the monitoring control system are arranged on the box body. According to the high-voltage electric field and hot air combined drying device provided by the invention, the structural design is reasonable, the operability is strong, and the use is convenient; compared with traditional hot air drying, the drying efficiency is high, the drying temperature is low, the drying time can be shortened by 50% than the drying time of drying by pure hot air under the same temperature, the drying energy consumption can be reduced by 51.9%, the high-voltage electric field and hot air combined drying device is particularly suitable for drying materials containing thermal-instability active components, for example, drying the materials of traditional Chinese medicine, medicinal slices, drug, agricultural products, food, biological products and the like, the appearance quality after the drying is good, the reservation degree of the active components is high, and the application range is very wide.

Description

technical field [0001] The invention relates to a drying processing production equipment, in particular to a high-voltage electric field combined hot air drying device suitable for drying materials containing thermally unstable active components in the fields of Chinese medicinal materials, medicines, agricultural products, food and biological products. Background technique [0002] Raw materials containing thermally unstable active components, such as Chinese herbal medicines, are prone to changes in appearance such as discoloration, surface hardening and cracking, excessive shrinkage, and reduced rehydration at higher drying temperatures, or the active ingredients contained in them are prone to decomposition, failure or volatilization loss of Chinese herbal medicines. For example, wolfberry is easy to change color and crack at high temperature; chrysanthemum and honeysuckle are not only easy to change color at high temperature, but also their active ingredients, chlorogeni...

Problems solved by technology

But its disadvantage is that the drying speed is relatively slow

[0004] At present, there are no reports at home and abroad on the drying equipment that uses the combination of high-voltage electric field and hot air to dry raw materials such as Chinese medicinal materials, fruits and vegetables, and bacteria.
