Description

Technical Field

[0001] This application relates to the field of traditional Chinese medicine processing technology, and specifically discloses a heating device for the production of prepared slices of traditional Chinese medicine. Background Technology

[0002] Prepared medicinal herbs are Chinese medicinal materials that have undergone processing based on traditional Chinese medicine theories and methods, and can be directly used in clinical practice. The production process of prepared medicinal herbs involves a drying step to remove moisture and also to sterilize the herbs.

[0003] The drying of Chinese herbal medicine slices is accomplished by a heating drying device. Traditional heating drying devices employ methods such as air drying and oven drying. For heating devices that use air drying, several trays are usually installed inside to hold the Chinese herbal medicine slices to be dried. Hot air is supplied through a unified air source, and the continuously supplied hot air heats the Chinese herbal medicine slices, thereby drying them and removing the evaporated moisture.

[0004] However, in order to meet the drying efficiency, the Chinese herbal medicine slices placed on the tray are stacked in several layers. However, when the stacked Chinese herbal medicine slices are dried with hot air, the stacked parts will be affected by the heat, which will block the hot air from entering and slow down the drying speed. Existing Chinese herbal medicine slice heating devices do not have a structure to shake the Chinese herbal medicine slices on the tray to separate the contact parts of the stacked Chinese herbal medicine slices.

[0005] This utility model provides a heating device for the production of Chinese herbal medicine slices in order to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that in traditional Chinese medicine drying devices that use hot air to dry medicinal herbs, the stacked medicinal herbs on the trays block the entry of hot air, thus slowing down the drying process.

[0007] To achieve the above objectives, the basic solution of this utility model provides a heating device for the production of traditional Chinese medicine decoction pieces, including a bellows with a cover on one side, a connecting platform fixed inside the bellows, and several carrying structures slidably connected to the connecting platform and slidable out of the bellows. The bellows has an air inlet structure at the top and an air outlet structure on one side of the bottom. The carrying structure includes a plate slidably connected to the connecting platform, a tray vertically slidably limited connected to the plate, and a spring on the plate for lifting the tray upwards. A vertical pressure rod passes through the bellows, and a reset structure for lifting the pressure rod upwards is provided at the bottom of the bellows. The bellows has a pressing structure for continuously pressing the pressure rod downwards, and the pressure rod has several pressing parts for pressing down the trays respectively.

[0008] Furthermore, the air intake structure includes an air guide box fixed to the top of the air box, an air duct connecting the bottom of the air guide box and the top of the air box, and an inclined air guide plate fixed in the air duct. The air guide box is connected to an air intake pipe for introducing hot air.

[0009] Furthermore, the tray has a through groove and a net for holding Chinese herbal medicine slices is fixedly connected to it.

[0010] Furthermore, the connecting platform has several slides extending through it, facing the box cover and used to accommodate the ramp, and a handle is fixedly connected to the end of the ramp facing the box cover.

[0011] Furthermore, the pallet has outwardly protruding sliding plates on both sides of the end near the mounting plate. The mounting plate has a receiving groove for accommodating the end of the pallet. The mounting plates on both sides of the receiving groove have vertical sliding grooves for the sliding plates to slide inside. A spring is fixed between the receiving groove and the bottom of the pallet.

[0012] Furthermore, the pallet extends outward to form a support plate for supporting the other end of the pallet, and a spring is fixed between the support plate and the bottom of the pallet above.

[0013] Furthermore, the tray has a pressure groove, and the lower pressing component includes a fixed ring coaxially fixed to a pressure rod above the plate and a pressure block fixed to the fixed ring and pressable into the pressure groove.

[0014] Furthermore, a second slide rail is provided through the connecting platform and faces the box cover. A third slide rail is provided on the inner side of the connecting platform to connect the second slide rail with the inner cavity of the bellows. A connecting plate is fixed to the pressure rod and extends into the second slide rail through the third slide rail. A fourth slide rail is provided on the bellows for the pressure rod to slide. A handle is fixed to the free end of the connecting plate.

[0015] The principle and effect of this solution are as follows:

[0016] 1. Compared with the prior art, the present invention uses a tray to hold the Chinese herbal medicine slices to be heated and dried, and introduces a dry hot airflow through the air inlet structure to heat the Chinese herbal medicine slices in the air box. The dry hot airflow carries away the moisture and discharges it from the air outlet structure, thus completing the heating and drying of the Chinese herbal medicine slices.

[0017] 2. Compared with the prior art, this utility model controls the pressure rod to reciprocate downward during the heating and drying process by pressing in a pressing structure. The pressure rod drives the lowering component to reciprocate downward on the tray. By pressing down on the tray and cooperating with spring 1, the tray moves vertically back and forth, thereby shaking the Chinese herbal medicine pieces on the tray and exposing their original stacked parts. This reduces the drying time required and solves the problem in traditional Chinese herbal medicine heating devices that use hot air to dry the herbs, where the stacked parts of the herbs on the tray block the hot air from entering, thus slowing down the drying speed.
