Description

Technical Field

[0001] This application relates to the field of traditional Chinese medicine drying technology, and in particular to a drying oven for traditional Chinese medicine decoction pieces. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces are products obtained after a series of processing steps on raw medicinal materials. Due to the inherent moisture content of the raw materials and the retention of moisture during processing, the resulting TCM decoction pieces typically contain moisture, providing a suitable environment for the growth and reproduction of microorganisms such as mold. Therefore, drying is necessary to inhibit mold growth. Currently, common drying methods include natural air drying and heat drying. Natural air drying involves placing the TCM decoction pieces outdoors to dry slowly under sunlight and wind. This process is not only time-consuming, but also allows bacteria and pests to remain due to prolonged contact with the external environment, leading to a decrease in quality. While heat drying can isolate the TCM decoction pieces from external influences, the enclosed space can cause uneven heating, resulting in incomplete drying in certain areas. Utility Model Content

The placement plate is used to place Chinese herbal medicine slices, which are dried by the heat generated by the partition 20; the placement plate is slidably connected to the inner edge of the partition. One end of the connector is attached to the rear side of the partition, and the other end extends beyond the housing 10.

[0059] The partition 20 includes a horizontal plate 202 and two vertical plates 201, with the two vertical plates 201 positioned opposite each other on either side of the horizontal plate 202, giving the partition 20 an overall "U"-shaped structure. A hot air channel 2021 is provided within the horizontal plate 202, and an air inlet connecting pipe 103 is provided on the side wall of the horizontal plate. A group of vent holes 2020 communicating with the hot air channel 2021 is provided on the top surface of the horizontal plate. When the air inlet connecting pipe 103 supplies hot air to the hot air channel 2021, the hot air flows upward through the group of vent holes 2020. Each vertical plate 201 is fitted with a mounting groove, allowing the partition 20 to slide smoothly into the mounting groove. A sliding groove 2010 is provided on the inner side wall of each vertical plate, and slide rails 2011 are respectively provided at the upper and lower edges of the sliding groove 2010.

[0060] The placement panel includes a placement panel body 210 and a pulley assembly 212. The placement panel body 210 has a receiving space 211 for holding Chinese medicinal herbs. The placement panel body 210 is positioned above the partition panel 20. Each side wall of the placement panel body 210 extends toward the inner wall of the adjacent box panel. The two side walls facing the sliding groove 2010 extend into the sliding groove 2010, while the remaining side walls are spaced apart from the inner walls of their adjacent box panels. The pulley assembly 212 is mounted on the placement panel body 210 via a mounting base 213 and is matched with a slide rail 2011, allowing the placement panel body 210 to move toward or away from the box door 100 via the pulley assembly 212.

[0061] The connector includes a connecting block 220 and a sliding rod 221. The connecting block 220 is fixed to the side wall of the placement plate 210 facing the back plate 101. One end of the sliding rod is fixed to the side wall of the connecting block 220 facing the back plate 101, and the other end extends outward from the box body after passing through and slidably connecting to the sliding sleeve 107.

[0062] Wet Chinese herbal medicine slices are placed in the receiving space 211 of the placement plate 210, and the placement unit is placed inside the box 10 by sliding the vertical plate 201 into the mounting groove. The Chinese herbal medicine slices inside the box are dried by hot air delivered by the air inlet connection pipe 103.

[0063] The circulating hot air unit includes a first air duct 30, an adsorber 31, a delivery pump 32, a second air duct 33, a hot air blower 34, and a hot air inlet pipe 35. The adsorber 31 is used to dehumidify the gas; its two ends are connected to the output end of the first air duct and one end of the delivery pump, respectively. The input end of the first air duct is connected to the air outlet pipe 104; the input end of the second air duct is connected to the other end of the delivery pump. The hot air blower 34 has a first hot air inlet and a second hot air inlet. The first hot air inlet is used to input heated air, and the second hot air inlet is connected to the output end of the second air duct. The second hot air inlet is connected to the second air duct 33. One end of the hot air inlet pipe is connected to the output end of the hot air blower, and the other end is connected to the air inlet connection pipe 103. After hot air is input into the hot air blower 34, the hot air is blown into the hot air input pipe 35 until the hot air is transmitted to the hot air channel 2021 to dry the Chinese herbal medicine pieces. The hot air flowing upward through the ventilation hole group 2020 is output through the air outlet pipe 104 to the first air pipe 30 and then flows back to the hot air blower 34.

[0064] The drive unit, installed outside the housing, includes a movable plate 40, a cylinder 41, and a support frame 42. The movable plate 40 is located on the outer wall of the back panel and slidably connected to the guide block 102. The movable plate 40 is extended by the other end of a sliding rod, which protrudes outside the movable plate and is bolted to the movable plate 40. The cylinder 41 is installed outside the housing via the support frame 42, and its movable end is connected to the side wall of the movable plate. The cylinder 41 drives the movable plate 40 to slide back and forth along the extension direction of the guide block, thereby causing the placed plates to move in the same direction. When the placed plates contain Chinese medicinal herbs, the reciprocating sliding of the placed plates along the extension direction of the guide block causes the Chinese medicinal herbs to be turned over during the drying process, which helps to make the drying of the Chinese medicinal herbs more uniform and improves the drying efficiency.

[0065] Based on the above embodiments, the working principle of this application is as follows:

[0066] Wet Chinese herbal medicine slices are placed in the receiving space 211. After opening the box door 100 and aligning the sliding rod 221 with the mounting hole, the vertical plate 201 slides into the mounting groove, placing the unit inside the box. The box door 100 is closed, and hot air is supplied to the box by the circulating hot air unit to dry the Chinese herbal medicine slices. During the drying process, the cylinder 41 is activated, driving the movable plate 40 to move back and forth along the extension direction of the guide block to turn the Chinese herbal medicine slices. When drying is complete, the bolt 106 at the sliding rod is removed, the box door 100 is opened, and the partition 20 is pulled out of the box.

[0067] Based on the above embodiments, the advantages of this application are:

[0068] (1) In the process of drying Chinese herbal medicine pieces, this application sets the hot air channel 2021 in the horizontal plate 202. The hot air passes through the hot air channel 2021 to heat the bottom end of the partition piece. In addition, the cylinder 41 drives the movable plate 40 to drive the placement plate to slide and connect to the partition piece 20. As a result, the Chinese herbal medicine pieces contained in the placement plate 210 are turned over with the reciprocating movement of the placement plate 210, which helps to make the drying of Chinese herbal medicine pieces more uniform and improves the drying efficiency of Chinese herbal medicine pieces.

[0069] (2) This application adds a circulating hot air unit and a ventilation hole group 2020 at the horizontal plate, so that the hot air transmitted to the partition 20 flows upward through the ventilation hole group 2020 and is transmitted back to the hot air blower 34 through the air outlet pipe 104, thus saving costs.
