Description

Technical Field

[0001] The utility model relates to the technical field of traditional Chinese medicine decoction pieces processing equipment, and particularly relates to an environment-friendly and energy-saving hot air circulation oven for traditional Chinese medicine decoction pieces. Background Art

[0002] In the process of producing traditional Chinese medicine decoction pieces, it is necessary to dry the sliced medicinal materials. Drying can not only remove the excess moisture in traditional Chinese medicine, but also kill molds, pests and their eggs, so that the prepared decoction pieces can be stored for a long time without deterioration. Common drying methods include sun drying, oven drying, microwave, far-infrared heating, etc. Among them, most Chinese herbal medicines, such as aromatic leaf, flower and pericarp types, can adopt the airing method. This method uses sunlight to naturally dry the medicinal materials, with low cost. However, it is highly dependent on the weather. When encountering rainy days or large outdoor dust, it is extremely easy to contaminate the decoction pieces. The medicinal materials can also be dried by artificial heating methods such as ovens, but these methods require a large amount of energy, increase production costs and are extremely non-environmental. A new type of drying equipment is needed to solve the above problems. Content of the Utility Model

[0003] To solve the above problems, the utility model provides an environment-friendly and energy-saving hot air circulation oven for traditional Chinese medicine decoction pieces, which includes an oven. The bottom of the oven is provided with universal wheels, and the top of the oven is provided with a solar panel. The solar panel is electrically connected to a pluggable battery on the back side of the oven. The bottom of the heat exchange chamber of the oven is provided with a filtering mechanism communicating with the hot drying chamber. The louver fans of the filtering mechanism are docked with the input end of the guiding fan. The output end of the guiding fan is connected to the distribution chamber at the top of the hot drying chamber through the electric heating wire in the heat exchange chamber. A plurality of baking trays are slidably connected to the symmetric guide rails on both sides of the hot drying chamber.

[0004] Furthermore, the filtering mechanism includes a filtering box embedded in the partition between the heat exchange chamber and the hot drying chamber. The filtering box is provided with a plurality of vertically parallel bending plates, and the bending plates all bend downward. The adjacent bending plates are separated by dust filtering plates. The tail end slots of the adjacent bending plates are embedded with louver fans.

[0005] Furthermore, the distribution chamber is divided into several sub-chambers by baffles. The adjacent sub-chambers are communicated through control valves on the baffles. The bottom of the sub-chamber is provided with a diversion plate communicating with the hot drying chamber.

[0006] Furthermore, a leakage tray fitting the inner side wall is arranged inside the baking tray. Pulleys are arranged at the bottoms of the skirt edges on both sides of the baking tray, and the pulleys are slidably connected to the chutes on the same side of the guide rail. A hook ring is arranged on the outer wall of the baking tray facing the oven door.

[0007] Furthermore, the bottom edge of the solar panel is hinged to the top of the oven. A plurality of support plate slots are opened on the top of the oven. One side of the support plate slot is hinged with a support rod that can be retracted into the slot, and the top of the support rod cooperates with the groove on the back of the solar panel.

[0008] The beneficial effects of the present utility model are as follows: The utility model sucks the air in the hot air drying chamber into the filtering mechanism through a guiding fan. The dust filtering plate in the filtering mechanism can filter out the dust in the air, and the condensed water vapor and grease in the air fall into the bending plate for collection. After the purified air is heated by the heating wire, it is redistributed to the hot air drying chamber by the distribution chamber to dry the traditional Chinese medicine slices on the baking tray. The baking tray adopts a double-layer structure, which can separate the debris in the slices and can slide freely on the guide rail through the hook rod, facilitating the operator to load and unload materials. The device can be moved outdoors for solar charging, and is not easily polluted compared with traditional direct sunlight, having the characteristics of energy conservation and environmental protection.
