Embodiment Construction

[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0030] refer to figure 1 , figure 2 ,

[0031] The alternating hot and cold air drying system includes a drying cylinder 1 and a heat pump 2 connected to the drying cylinder. An air inlet duct 11 is arranged between the air outlet of the heat pump and the drying cylinder, and a cooling fan 3 whose outlet The tuyere is connected to the drying cylinder 1 through an air inlet pipe 11; a photocatalyst device 12 is arranged inside the air inlet pipe 11.

[0032] The present invention alternately uses hot and cold air to dry the medicinal materials in the drying cylinder. First, the cold air blower 3 air-dries the medicinal materials in the drying cylinder 1. After the moisture on the surface of the medicinal materials is basically dried, the heat pump ...

Abstract

The invention relates to the field of pharmaceutical manufacturing equipment, in particular to a drying system. A cold and hot air alternative drying system comprises a drying cylinder and a heat pump connected with the drying cylinder; an air inlet pipeline is arranged between an air outlet of the heat pump and the drying cylinder; the cold and hot air alternative drying system further comprises a cold air blower; and an air outlet of the cold air blower is communicated with the drying cylinder through the air inlet pipeline. A photocatalyst device is arranged in the air inlet pipeline. Due to the adoption of the technical scheme, herbs are dehydrated at first, and then are dried through alternation of cold air and hot air to fully ensure the drying property of herbs; and the arrangement of the photocatalyst device solves the problem of sterilization of the cold air and hot air in the drying process.

Description

technical field [0001] The invention relates to the field of pharmaceutical equipment, in particular to a drying system. Background technique [0002] Choosing an appropriate drying method to process Chinese herbal medicines has always been one of the important topics in the continuous exploration of Chinese medicine processing. Most of the traditional drying systems adopt drying methods such as mechanical method, heating method and chemical adsorption method. The most common method of drying medicinal materials is the heating method, that is, using a drying medium such as hot air to heat the material and the moisture in it through convective heat exchange. [0003] However, with the continuous strengthening of the quality management of medicine bottles, higher requirements have been put forward for the hygienic indicators of the production of traditional Chinese medicine preparations. Only heating the medicinal materials for drying processing can no longer meet the requir...
