[0002] As we all know, medicinal materials are raw materials for making medicines. In China, they especially refer to traditional Chinese medicines, that is, raw materials of traditional Chinese medicine that have not been processed or made into finished products. Usually, traditional Chinese medicines need to be dried in a baking oven during production. A baking oven is a device used for heat treatment and baking food or other items. It usually consists of a closed heating chamber and a control system, which can provide a specific temperature and time to complete the baking process.

[0003] The patent document with the authorization publication number CN217442122U is a hot air circulation oven for medicinal materials, including a box body and a placement plate, a heating pipe is provided in the box body, a fan is installed on the side wall of the box body, the heating pipe corresponds to the position of the fan, and an air inlet pipe is provided at the upper end of the box body. By pulling the spring outward, the spring moves, and the block moves. The spring is compressed, and the block will no longer block the positioning block. The user rotates the air inlet pipe to rotate the cylinder body. The rotation of the cylinder body will drive the positioning block to rotate, so that the positioning block rotates into the slot. The cylinder body and the filter can be taken out by moving the air inlet pipe upward.

[0004] However, the above prior art still has the following problems:

[0005] The above-mentioned prior art does not fully dry the medicinal materials, resulting in uneven drying of the medicinal materials. Manual turning of the medicinal materials is required, which greatly reduces the drying efficiency. Utility Model Content

[0006] The purpose of the utility model is to address the deficiencies of the existing technology and propose a two-way penetrating open oven to solve the technical problems mentioned in the background technology that the existing technology does not dry medicinal materials uniformly and requires manual turning, resulting in low drying efficiency.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A two-way penetrating open oven, comprising:

[0009] oven;

[0010] A fixed partition, which is vertically fixed to the inner wall of the oven and divides the inner cavity of the oven into a heating chamber and a drying chamber from left to right;

[0011] A heating mechanism, wherein the heating mechanism is fixed in the heating chamber, and the fixed partition is provided with a first passage and a second passage, respectively, from top to bottom, which are connected to the heating chamber and the drying chamber, and the heating mechanism delivers hot air to one of the first passage or the second passage, but does not deliver hot air to the other;

[0012] A perforated partition, wherein the three outer walls of the perforated partition are fixed to the inner wall of the drying chamber, one end of the perforated partition is fixed to the fixed partition, and an air duct 1 connected to the opening 1 is formed between the perforated partition and the top wall of the oven;

[0013] A material cart is provided at one end of the oven with an opening 1 for the feeding cart to pass through, a second opening is provided at the bottom of the oven with the feeding cart embedded therein and connected to the opening 1, the lower end of the material cart can block the opening 2, a second air duct is provided at the bottom of the material cart to connect to the second opening, the second air duct is located above the second opening, a vent connected to the upper end of the second air duct is provided on the bottom wall of the material cart, a mesh plate is fixed at the upper end of the vent, and a sealing door for blocking the opening 1 is hinged at one end of the oven.

[0014] Working principle:

[0015] Start the heating mechanism to deliver hot air to the passage one. At this time, the heating mechanism does not deliver hot air to the passage two. The hot air enters the air duct one through the passage one. The hot air in the air duct one enters the drying chamber through the holes in the perforated partition and blows toward the medicinal materials on the upper end of the mesh plate in the material cart, thereby achieving drying of the medicinal materials. Start the heating mechanism to deliver hot air to the passage two. At this time, the heating mechanism does not deliver hot air to the passage one.
