Energy-saving codonopsis medicine drying system with automatic circulating temperature difference compensation function

Abstract

The invention discloses an energy-saving codonopsis medicine drying system with an automatic circulating temperature difference compensation function. The energy-saving codonopsis medicine drying system with the automatic circulating temperature difference compensation function is characterized in that the system is mainly composed of a temperature compensation device, a drying air duct (1), an air intake duct (2) arranged above the drying air duct (1), a dehumidifier (3) arranged at an air inlet of the air intake duct (2), an exhaust fan (4) arranged at an air outlet of the air intake duct (2), and the like; the temperature compensation device is composed of a control system (71), a transmission device, a heater (73) and an air blower (72); and the control system (71) is composed of a control chip, a mixed signal processing circuit, a trilinear driving circuit, a current regulating circuit, a temperature sensor (74) and a buzzer. According to the energy-saving codonopsis medicine drying system with the automatic circulating temperature difference compensation function, a traditional electric heating device is replaced with a heat pump, so that the power consumption of the system is only one fourth that of a traditional drying device; and through the arrangement of the temperature compensation device, the stability of drying temperature and the drying efficiency of the system are effectively improved.

Description

technical field [0001] The invention relates to the field of energy conservation and environmental protection, in particular to an energy-saving system for drying and drying Codonopsis pilosula medicinal materials with circular temperature difference automatic compensation. Background technique [0002] Traditional Chinese medicine has a long history in our country, and its treatment method based on conditioning is favored by patients at home and abroad. Many medicinal materials used in traditional Chinese medicine need to be dried. "Dangshen" is a traditional Chinese medicinal material commonly used in Chinese medicine. It requires high temperature accuracy during drying. If the temperature is low, the "Codonopsis" will not be dry enough, and it will become moldy or deteriorate during long-term storage. [0003] However, most of the existing Chinese herbal medicines are dried by means of electric baking, because the power consumption of this drying method is very high, and...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects of not only unstable drying temperature but also low drying efficiency when drying the traditional Chinese medicinal material "Dangshen" in the prior art, and provide a kind of Codonopsis medicinal material that uses cyclic temperature difference automatic compensation to dry and save energy. system
