Traditional Chinese medicinal material drying device

Abstract

The invention discloses a traditional Chinese medicinal material drying device. The traditional Chinese medicinal material drying device comprises a cube box, multi-layer conveying belts arranged in the cube box, protection devices arranged below all layers of conveying belts, rakes arranged over all layers of conveying belts, a feeding port formed in the top of one end of the cube box, a discharging port formed in the other end of the cube box and a moisture discharging port, wherein the moisture discharging port is formed in cube box and in the 1 / 2 upper position of the same end with the feeding port. The vertical side face, adjacent to the discharging port, of the cube box is provided with a plurality of fan sets. An air supply port is formed between every two adjacent fan sets. The side wall of the cube box is provided with an air return port, a speed changing box is arranged behind the cube box, and a conveying device is arranged on the left of the drying device. The drying deviceis used for drying traditional Chinese medicinal materials such as codonopsis pilosula, asparagus and fructus cannabis, the drying efficiency is improved, and influences from inner humidity are avoided.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a high-efficiency heat pump type drying device. Background technique [0002] The drying of Chinese herbal medicine is the primary link in the processing of Chinese herbal medicine in my country. The drying of Chinese herbal medicine is mainly natural drying, which occupies a large area, has a long drying cycle and low production efficiency. , resulting in a decrease in the quality of the medicinal material, labor and time-consuming, and increased labor intensity. [0003] The traditional Chinese herbal medicine drying box in the prior art has the following defects: because the Chinese herbal medicines are usually stacked and stacked on the pallets of the drying Zhuangzi, the solid air permeability becomes poor, the drying hot air is difficult to penetrate the materials of the Chinese herbal medicines, the drying efficiency is low, and the drying efficiency is low. Long time, the ...

[0002] The drying of Chinese herbal medicine is the primary link in the processing of Chinese herbal medicine in my country. The drying of Chinese herbal medicine is mainly natural drying, which occupies a large area, has a long drying cycle and low production efficiency, and it is easy to cause uneven drying quality of medicinal materials during the drying process. , resulting in a decline in the quality of medicinal materials, labor-intensive and time-consuming, and increased labor intensity, it is easy to cause cracks in the appearance of Chinese medicinal materials, loss of efficacy, and easy to damage the internal structure of medicinal materials during the drying process, thereby reducing the original quality of medicinal materials

[0003] The traditional Chinese medicinal material drying box in the prior art mainly has the following defects: because the traditional Chinese medicinal materials are usually stacked and placed on the pallets of the drying farm, the solid air permeability becomes poor, and it is difficult for the dry hot air to penetrate the materials of the Chinese medicinal materials, the drying efficiency is low, and the drying The drying time is long, and the drying effect is uneven; and the long-time drying will cause the plate to heat up, which will affect the medicinal properties of Chinese herbal medicines

However, this air supply method causes air temperature differences in the vertical direction, resulting in uneven drying of Chinese herbal medicines, reducing the drying quality, and the drying effect is not good.
