Medicinal material drying equipment

Abstract

The invention provides medicinal material drying equipment. The medicinal material drying equipment comprises a drying box, a feed hopper, a receiving box and a vacuum pumping device. The drying box is internally provided with a drying device, a material collection block and a lifting device. The drying device comprises a first drying unit and a second drying unit. The first drying unit and the second drying unit each comprises a material conveyor belt, ultrasonic transducers located below the material conveyor belt, a driving motor and an infrared ray lamp pole located above the material conveyor belt. A material scattering device is arranged above the first drying unit. Material retaining plates are arranged below the second drying unit. Limiting grooves and bristles are arranged above the material retaining plates. The lifting device is located on one side of the drying device. The medicinal material drying equipment conducts drying on medicinal materials through combination of ultrasound and infrared, is good in drying effect and capable of completely maintaining the original color, luster and flavor of the medicinal materials, conducts vacuum pumping on the interior of the drying box through the vacuum pumping device, can improve the drying efficiency and prevent vapor from wetting the medicinal materials again and is good in drying effect.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to medicinal material drying equipment. Background technique [0002] Traditional Chinese herbal medicine drying methods mainly include shade drying, sun drying and drying. [0003] The traditional drying method of medicinal 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 materials cannot be well preserved, which affects the appearance of medicinal materials. [0004] In view o...

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.
