Medicinal material circulation energy-saving drying machine for traditional Chinese medicinal material processing and using method thereof

Abstract

The invention relates to a medicinal material circulation energy-saving drying machine for traditional Chinese medicinal material processing and a using method thereof, and belongs to the technical field of traditional Chinese medicinal material processing. The medicinal material circulation energy-saving drying machine is characterized in that a circulating conveying assembly is internally provided with at least five groups of conveyors which are distributed in an S shape, so that the drying processing time of lotus seeds in a drying box is shortened, the lotus seeds are conveyed through a receiving hopper in the circulating conveying assembly, through meshes and taper angles densely distributed on the surface of a conveying mesh belt in the circulating conveyor, the air permeability of the surface of the conveying mesh belt is improved, and the contact area of hot air and traditional Chinese medicinal materials is increased; in addition, through the meshes, the purpose that hot air in the drying box can penetrate through the meshes of the conveying mesh belt from bottom to top in a convection mode to rapidly dry and process the lotus seeds placed on the conveying mesh belt is achieved. The fully utilizes heat in the drying box, and improves the drying efficiency and energy saving performance of the dryer.

Description

technical field [0001] The invention relates to the technical field of processing Chinese herbal medicines, and more specifically, to a material circulation and energy-saving drying machine for processing Chinese medicinal materials and a method for using the same, which are used for drying and processing lotus seeds. Background technique [0002] The processing of lotus seeds is required to achieve complete body shape, dry body without impurities, good color, unchanged odor, and less damage to active ingredients. Among them, the commonly used methods of drying lotus seeds include drying in the sun, drying in the shade, and drying. And it is easy to be mixed with impurities, so Chinese herbal medicines are mostly dried using a closed-type dryer for processing, which is energy-saving, heat-preserving, dry and pollution-free to ensure the high-quality medicinal properties of lotus seeds. [0003] The drying process of lotus seeds is to dehydrate the lotus seeds and maintain th...

Problems solved by technology

[0003] The drying process of lotus seeds is to dehydrate the lotus seeds and maintain their original ingredients and medicinal properties. Drying is to allow them to be stored for a long time, but when the lotus seeds are dried and processed at a certain temperature, they will be It loses its medicinal effect, so it is very important to control its temperature during the drying process; a large amount of water vapor will be formed in the dryer during the drying process of lotus seeds, and this part of the water vapor also needs to be discharged in time The dryer will not affect the drying effect of lotus seeds; in addition, since the dried material is lotus seeds, a clean heat source must be used to heat the air to avoid pollution to lotus seeds. In addition, industrial power consumption is large, and many places have begun to implement industrial Electricity restriction measures, so there is an urgent need for a recycling energy-saving dryer for Chinese herbal medicines, which can control the temperature and humidity in the dryer in real time and can realize the recycling of hot and dry air, while ensuring the drying effect of lotus seeds. At the same time, it saves power to the greatest extent
