A decompression drying equipment suitable for the processing of medicinal materials and food materials

Abstract

The invention provides decompression drying equipment suitable for processing of medicinal materials and food materials. The decompression drying equipment comprises a drying box, a feeding hopper, areceiving box and a vacuumizing device. A drying device, a collecting block and a lifting device are arranged in the drying box. The drying device comprises a first drying unit and a second drying unit which each comprise a material conveyor belt, an ultrasonic transducer located below the material conveyor belt, a driving motor and an infrared lamp pole located above the material conveyor belt. Amaterial dispersing device is arranged above the first drying unit. Baffles are arranged below the second drying unit, limiting grooves and brush bristles are arranged above the baffles, and the lifting device is located on one side of the drying device. According to the decompression drying equipment, original colors and flavor of the medicinal materials can be completely maintained, and the vacuumizing device is adopted to vacuumize the interior of the drying box so that the medicinal materials can be prevented from being wet again by water vapor while the drying efficiency is improved, andthe drying effect is good.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a decompression drying equipment suitable for processing medicinal materials and food materials. Background technique [0002] Traditional Chinese herbal medicines and ingredients drying methods mainly include shade drying, sun drying and oven drying. [0003] The traditional drying method of medicinal materials and food materials has low drying efficiency and long drying cycle, which cannot meet the requirements of modern medicinal materials drying. And the traditional drying method has a certain damage to the active ingredients in the medicinal materials, especially for the drying of some medicinal materials containing volatile ingredients, in which the volatile ingredients are easy to volatilize, resulting in the loss of active ingredients and affecting the quality of the medicinal materials; and the traditional drying method The color and luster of medicinal materia...

Problems solved by technology

However, the drying oven is heated by the heating device, which cannot ensure the color of the material well. At the same time, the heating device is used to heat the material, so that the surface temperature of the material is higher than the internal temperature, the moisture inside the material is not easy to discharge, and the drying effect is not good.
