Description

Technical Field

[0001] This utility model belongs to the field of Polygonatum production technology, specifically relating to a special processing and drying equipment for Polygonatum. Background Technology

[0002] Polygonatum grows in mountain forest edges, thickets, or semi-shaded slopes, and is distributed in regions north of the Yangtze River. Polygonatum is highly selective in its growth environment, preferring shady and moist environments, loose and fertile soil with sufficient surface moisture, and good shade and light penetration in forest edges; it is suitable for soils with moderate to slightly acidic pH; it is propagated by rhizomes and seeds, with rhizomes being the primary method of propagation.

[0003] The processing of Polygonatum generally involves the following steps: harvesting, removing impurities, washing, steaming, drying, and packaging.

[0004] Chinese Patent CN201921823942.4 discloses a steaming and drying device for processing Polygonatum sibiricum, comprising a box body with a lid mounted on the upper end of the box body via a locking mechanism. Three storage mesh boxes are arranged side-by-side and rotatably inside the upper end of the box body. The middle storage mesh box is connected to the motor output shaft via a transmission rod, and the middle storage mesh box is connected to the driven transmission gears on the storage mesh boxes at both ends via a main transmission gear. A heat-conducting plate is horizontally installed at the lower end of the box body, and a heating wire is provided on the lower surface of the heat-conducting plate. Compared with the prior art, the beneficial effects of this utility model are: the motor drives the middle storage mesh box to rotate, and the main and driven transmission gears drive the storage mesh boxes at both ends to rotate, ensuring uniform steaming and drying of Polygonatum sibiricum within the box body; water is added to the box body above the heat-conducting plate, and the heating wires steam and boil the Polygonatum sibiricum within the storage mesh boxes; during drying, the water in the box body is drained, and the heat conducted by the heating wires to the heat-conducting plate dries the Polygonatum sibiricum within the storage mesh boxes. The previous method involved draining the internal water before drying, which achieved good drying results. However, the drainage process was slow, affecting the drying efficiency. To address this, a specialized steaming and drying device for processing Polygonatum was designed. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a special steaming and drying equipment for processing Polygonatum odoratum, so as to solve the problems in the background technology.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A special processing and drying device for Polygonatum sibiricum includes an oven and an evaporation device. The oven has a closable door on one side. Inside the oven, there are several layered grid plates for supporting Polygonatum sibiricum and a drying assembly for generating heat to dry the Polygonatum sibiricum. One end of the evaporation device is connected to the side of the oven opposite the door. The top of the oven is connected to a second tube, which is connected to the other end of the evaporation device. The evaporation device, the second tube, and the oven form a circulating loop.

[0008] By adopting the above structural design, the special processing steaming and drying equipment for Polygonatum includes two main structures: a drying oven and an evaporation device. The drying oven and the evaporation device are connected by a second pipe. The evaporation device, the second pipe, and the drying oven form a circulating loop. High-temperature steam generated in the evaporation device is directly introduced into the drying oven to steam the Polygonatum on the grid plate. The high-temperature steam then flows back to the evaporation device along the second pipe, reducing heat loss in the entire system. After the Polygonatum is steamed, the drying components in the drying oven directly dry the Polygonatum, thus completing the entire steaming and drying process of Polygonatum. There is no need to transfer the Polygonatum or drain water, thereby improving the efficiency of Polygonatum processing.

[0009] Furthermore, the evaporation apparatus includes;

[0010] The first tube is horizontally arranged, and a gas collection hood connected to the oven is located on the side of the first tube near the oven. An openable tube cover is provided at the end of the first tube away from the oven.

[0011] An evaporator is fixedly connected to the lower part of the first tube body. A heater is installed inside the evaporator. A water inlet pipe is connected to the evaporator, and a control valve is installed on the water inlet pipe.

[0012] Furthermore, the gas collecting hood is funnel-shaped, and the diameter of the side of the gas collecting hood near the evaporator is larger than the diameter of the side near the first tube.

[0013] Furthermore, there are two drying components, with the two sets of drying components respectively located at the bottom and top of the drying oven.

[0014] Furthermore, the drying assembly includes a connector and several electric heating coils, which are arranged along the length of the drying oven. The electric heating coils are connected to the connector and connected to a power source through the connector.

[0015] By adopting the above structural design, the chamber door is opened, the Polygonatum sibiricum to be processed is laid on the grid plate, and then placed on the horizontal support column of the chamber. The chamber door is closed and the evaporation device is started. The heater in the evaporation device heats and boils the water in the evaporation chamber to generate high-temperature steam, which enters the drying oven through the gas collection hood. The gas collection hood has a larger diameter near the drying oven, which is more conducive to the full contact between the upper and lower layers of Polygonatum sibiricum and the high-temperature steam. After the steaming is completed, the pipe cover can be opened to restore the gas pressure of the device. Then the drying component is started to dry the Polygonatum sibiricum. Since the electric heating coils are arranged at the upper and lower ends of the chamber, the Polygonatum sibiricum placed in the middle can be effectively dried, improving the drying efficiency.

[0016] Furthermore, the oven includes a horizontally arranged chamber, the inner wall of which is provided with vertical support columns for supporting the grid plate, and the bottom of the chamber is connected to a base.

[0017] Furthermore, a horizontal support column is connected to the bottom of the evaporation device.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] 1. This specialized processing and drying equipment for Polygonatum includes two main structures: a drying oven and an evaporation device. The drying oven and the evaporation device are connected by a second pipe. The evaporation device, the second pipe, and the drying oven form a circulating loop. High-temperature steam generated in the evaporation device is directly introduced into the drying oven to steam the Polygonatum on the grid plate. The high-temperature steam then flows back to the evaporation device along the second pipe, reducing heat loss in the entire system. After the Polygonatum is steamed, the drying components in the drying oven directly dry the Polygonatum, thus completing the entire steaming and drying process of Polygonatum. There is no need to transfer the Polygonatum or drain water, thereby improving the efficiency of Polygonatum processing.

[0020] 2. The device has a simple structure, is easy to operate, reduces the need for handling during the processing of Polygonatum odoratum, and is highly practical. Attached Figure Description

[0032] Example 1:

[0033] like Figure 1-5 As shown, this utility model is a special processing and drying device for Polygonatum sibiricum, comprising an oven 1 and an evaporation device 2. The oven 1 has a closable door 12 on one side. Inside the oven 1, there are several layered grid plates 6 for carrying Polygonatum sibiricum and a drying assembly 5 for generating heat to dry the Polygonatum sibiricum. One end of the evaporation device 2 is connected to the side of the oven 1 opposite to the door 12. The top of the oven 1 is connected to a second tube 3, which is connected to the other end of the evaporation device 2. The evaporation device 2, the second tube 3, and the oven 1 form a circulating loop. This specialized processing and drying equipment for Polygonatum includes two main structures: an oven 1 and an evaporation device 2. The oven 1 and the evaporation device 2 are connected by a second pipe 3. The evaporation device 2, the second pipe 3, and the oven 1 form a circulating loop. High-temperature steam generated in the evaporation device 2 is directly introduced into the oven 1 to steam the Polygonatum on the grid plate 6. The high-temperature steam then flows back to the evaporation device 2 along the second pipe 3, reducing heat loss in the entire system. After the Polygonatum is steamed, the drying component 5 in the oven 1 directly dries the Polygonatum, thus completing the entire steaming and drying process of Polygonatum. There is no need to transfer the Polygonatum or drain water, thereby improving the efficiency of Polygonatum processing.

[0034] In this embodiment, the evaporation device 2 includes: a first tube 22, which is horizontally arranged, with a gas collecting hood 23 connected to and communicating with the oven 1 on the side of the first tube 22 near the oven 1, and an openable tube cover 24 at the end of the first tube 22 away from the oven 1; and an evaporation chamber 21, which is fixedly connected to the lower part of the first tube 22, with a heater installed inside the evaporation chamber 21, and a water inlet pipe 211 connected to the evaporation chamber 21, with a control valve installed on the water inlet pipe 211. The gas collecting hood 23 is funnel-shaped, and the diameter of the side of the gas collecting hood 23 near the evaporation chamber 21 is larger than the diameter of the side near the first tube 22.

[0035] In this embodiment, there are two drying components 5, which are respectively arranged at the bottom and top of the oven 1. The drying component 5 includes a connector 51 and several electric heating coils 52. The electric heating coils 52 are arranged along the length of the oven 1 and are connected to the connector 51, and connected to the power supply through the connector 51. By adopting the above structural design, the chamber door 12 is opened, and the Polygonatum sibiricum to be processed is laid on the grid plate 6 and then placed on the horizontal support column 4 of the chamber body 11. The chamber door 12 is closed, and the evaporation device 2 is started. The heater inside the evaporation device 2 heats and boils the water in the evaporation chamber 21, generating high-temperature steam that enters the drying oven 1 through the gas collecting hood 23. The gas collecting hood 23 has a larger opening near the drying oven 1, which is more conducive to the full contact between the upper and lower layers of Polygonatum sibiricum and the high-temperature steam. After steaming, the pipe cover 24 can be opened to restore the air pressure of the device, and then the drying component 5 is started to dry the Polygonatum sibiricum. Since the electric heating coil 52 is arranged at the upper and lower ends of the chamber body 11, it can effectively dry the Polygonatum sibiricum placed in the middle, improving the drying efficiency. In practical applications, temperature monitoring instruments and air pressure monitoring instruments can also be configured for the equipment to monitor the temperature and air pressure of the equipment and better control the equipment.

[0036] In this embodiment, the oven 1 includes a horizontally arranged chamber 11, with vertical support columns 14 for supporting the grid plate 6 provided on the inner wall of the chamber 11, and a base 13 connected to the bottom of the chamber 11. The bottom of the evaporation device 2 is connected to a horizontal support column 4.

[0037] Working principle: Open the box door 12, lay the Polygonatum to be processed on the grid plate 6, and then place it on the horizontal support column 4 of the box body 11. Close the box door 12 and start the evaporation device 2. The heater in the evaporation device 2 heats and boils the water in the evaporation box 21 to generate high-temperature steam. The steam enters the drying oven 1 through the gas collection hood 23. The gas collection hood 23 is closer to the drying oven 1 and has a larger opening, which is more conducive to the full contact between the upper and lower layers of Polygonatum and the high-temperature steam. After the steaming is completed, the pipe cover 24 can be opened to restore the air pressure of the device. Then the drying component 5 is started to dry the Polygonatum. Since the electric heating coil 52 is arranged at the upper and lower ends of the box body 11, it can effectively dry the Polygonatum placed in the middle, improving the drying efficiency.
