Problems solved by technology

[0006] The design principle of the present invention is: in order to solve the problem that the wind and heat will cause medicinal materials to fly everywhere, the present invention starts from the idea of ​​changing the heat source, adopts a resistance heating device as the heat source, and uses thermal radiation for heating, although the drying speed of this method is relatively fast. Slow, but the quality of the finished medicinal materials is higher

Embodiment 1

[0019] like Figure 1 to Figure 2 shown.

[0020] The crawler type resistance heating medicinal material dryer includes a heating box 1 and a transmission crawler 2 that runs through the heating box 1 and is used to carry medicinal materials. The left side of the transmission crawler 2 is provided with a resistance heater A21, and the right side of the transmission crawler 2 is provided with a As for the resistance heater B22, along the conveyance direction of the conveyance crawler 2, the resistance values ​​of the resistance heater A21 and the resistance heater B22 are gradually increased.

[0021] The design principle of the present invention is as follows: in order to solve the problem that the wind and heat will cause the medicinal materials to fly everywhere, the present invention starts from the idea of ​​changing the heat source, adopts a resistance heating device as the heat source, and uses heat radiation for heating, although the drying speed of this method is relat...

Embodiment 2

[0025] The difference between this embodiment and Embodiment 1 is that the transmission line of the conveying crawler belt 2 generally moves straight along its axis. Therefore, it is preferable that the resistance heater A21 and the resistance heater B22 are composed of several heating resistance plates 4 arranged in line in sequence. , along the transmission direction of the transmission track 2 , the resistance of the heating resistor plate 4 increases sequentially. The resistance heater A21 and the resistance heater B22 are set as independent entities, and the heating value of the resistance heater A21 and the resistance heater B22 can be controlled away from each other according to different medicinal materials, so as to use the drying treatment of various medicinal materials.

[0026] Preferably, there are gaps between adjacent heating resistor disks 4 . to create gaps for air circulation.

[0027] Preferably, the gap value is between 5cm and 20cm.

[0028] Preferably, ...

Abstract

The invention discloses a crawler-type resistance heating medicinal material dryer which comprises a heating tank body (1) and a conveying caterpillar band (2) which penetrates through the heating tank body (1) and is used for carrying medicinal materials, a resistance heater A (21) is arranged on the left side of the conveying caterpillar band (2), a resistance heater B (22) is arranged on the right side of the conveying caterpillar band (2), and the resistance values of the resistance heater A (21) and the resistance heater B (22) are gradually increased in the conveying direction of the conveying caterpillar band (2). The crawler-type resistance heating medicinal material dryer has the advantages of being easy and convenient to operate, simple in structure, good in end product quality and low in input cost and maintaining cost.

Description

technical field [0001] The invention relates to a traditional Chinese medicine drying device, in particular to a crawler type resistance heating medicinal material drying machine. Background technique [0002] The traditional Chinese herbal medicine drying device adopts air heat drying. Hot water or waste heat from the factory is used for heat exchange to heat the air. The air generally needs to be dried before heating, and then the dry, high-temperature air is passed into the medicinal material storage area to dry the medicinal material. [0003] Based on the design of the existing technology and the special requirements of medicinal materials, for most Chinese medicinal materials, the dried medicinal materials are light in weight, some are leaves, some are roots, some are stems, and some are fruit particles. And if these Chinese herbal medicines are also treated by wind heat, it will cause the herbs in the drying chamber to fly everywhere, and the collision between the h...
