Description

Technical Field

[0001] This utility model relates to drying equipment, and more particularly to a drying equipment for processing Cordyceps militaris. Background Technology

[0002] Cordyceps militaris, also known as North Cordyceps, is a medicinal herb with high medicinal value. Processed Cordyceps militaris can also be consumed as a health food. Cordyceps militaris granules, made through drying and cutting, are often used for making tea, boiling in water, or infusing in alcohol. Currently, the main methods for drying Cordyceps militaris are artificial natural drying and mechanical drying. Mechanical drying methods include hot air drying, far-infrared drying, and freeze-vacuum sublimation drying. Freeze-vacuum sublimation drying not only completes the drying process but also ensures that the Cordyceps militaris can be restored to its pre-drying state after rehydration, maintaining its original appearance and high preservation of its medicinal value. Therefore, it is widely used by many factories.

[0003] Existing cryogenic vacuum sublimation drying equipment typically separates the heating and cooling equipment through an insulation layer. However, the presence of the insulation layer can affect heating efficiency during the heating process, thereby increasing factory operating costs. If no insulation layer is installed, although the heating efficiency is not affected, the heating electronic components are prone to damage during the cooling process. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices that separate heating and cooling equipment with insulation layers, which protect heating elements from low-temperature damage but affect heating efficiency and increase operating costs; and that removing the insulation layer does not affect heating efficiency but increases the risk of damage to heating elements, this utility model provides a drying equipment for processing Cordyceps militaris.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

A bearing 2 is located on the front left side of the housing 1, and a connecting frame 4 is hinged to the bearing 2. A door 3 is located on the rear side of the connecting frame 4. The door 3 is made of semi-transparent glass, and the semi-transparent glass material allows for... The operator can directly observe the drying process of the cordyceps inside the box 1 without opening the box door, which helps the operator to detect problems in time. An elastic sealing membrane 5 is located on the front side of the box 1, behind the box door 3. A screw 401 is located on the right front end of the connecting frame 4, passing through the connecting frame 4. A threaded groove is opened on the right front side of the box 1, which fits into the screw 401. Symmetrically distributed support frames 6 are located inside the box 1, used to support the tray containing the cordyceps. A control mechanism is located on the left side inside the box 1. The cooling mechanism 7 has a heat insulation layer 8 on the left side of the middle part of the box 1, and an electric guide rail 802 on the right side of the middle part of the box 1. A movable plate 801 is connected to the moving part of the electric guide rail 802. The movable plate 801 and the heat insulation layer 8 work together to form a sealing surface, dividing the box 1 into upper and lower parts. A heating plate 9 is provided on the inner bottom of the box 1. A control panel 13 is provided on the front side of the box 1. A temperature sensor 11 and a vacuum gauge 12 are provided on the rear side of the inside of the box 1. A first air pipe 15 and a second air pipe 16 are provided on the right side of the box 1. The room has a built-in vacuum pump and a gas pump. There are two first gas pipes 15, which are connected to the two ends of the vacuum pump respectively. There are two second gas pipes 16, which are connected to the two ends of the gas pump respectively. The two first gas pipes 15 and the two second gas pipes 16 pass through the inside of the right side of the box 1 and the outside of the box 1 respectively. The first gas pipes 15 and the second gas pipes 16 located on the outside of the box 1 are fitted with gas valves 14. The electric guide rail 802, heating plate 9, temperature sensor 11, vacuum gauge 12, gas valves 14, vacuum pump and gas pump are all electrically connected to the control panel 13.

[0024] like Figure 5 As shown, the refrigeration mechanism 7 includes a refrigeration chip 701, a heat-conducting column 702 and a heat sink 703. The refrigeration chip 701 is located on the left side of the interior of the housing 1. The heat-conducting column 702 is located on the left side of the refrigeration chip 701. The heat-conducting column 702 penetrates the housing 1. The heat sink 703 is located on the left side of the heat-conducting column 702.

[0025] like Figure 6 As shown, it also includes a sealing layer 803. The sealing layer 803 is provided on the top of the movable plate 801 and the heat insulation layer 8. The sealing layer 803 can reduce the possibility of cold air penetrating through the heat insulation layer 8 into the area where the heating plate 9 is located and forming condensation in the area when the refrigeration mechanism 7 is working, which may lead to damage to electronic components.

[0026] like Figure 4As shown, it also includes a fire-resistant plate 10. The bottom of the heating plate 9 is provided with a fire-resistant plate 10. The fire-resistant plate 10 is located between the heating plate 9 and the box 1. The fire-resistant plate 10 can block heat and prevent fire.

[0027] like Figure 3 As shown, it also includes casters 17. Casters 17 are provided at the bottom of the housing 1. Casters 17 make the equipment easy to move between different positions, reducing the labor cost and time consumption of handling.

[0028] Tighten screw 401 to unscrew it from the threaded groove, then open the chamber door 3. Place the tray containing the cordyceps to be dried on the support frame 6, close the chamber door 3, and twist screw 401 in the opposite direction. When the chamber door 3 closes, the elastic sealing membrane 5 is deformed by the chamber door 3, filling the gap between the chamber body 1 and the chamber door 3 to form a seal. Start the cooling chip 701 through the control panel 13. The cooling chip 701 absorbs the heat inside the chamber body 1 and uses the heat conduction column 702 to conduct the heat into the heat sink. 703, eventually diffused into the outside air, causing the temperature inside the chamber 1 to drop rapidly. The temperature sensor 11 detected that the temperature of the chamber 1 had dropped to the first preset temperature, which is the temperature at which the moisture inside the cordyceps can be completely frozen. Then, the air valve 14 on the first air pipe 15 was opened and the vacuum pump was started through the control panel 13. The vacuum pump evacuated the gas inside the chamber 1 to the outside of the chamber 1. After the air pressure inside the chamber 1 was evacuated to a vacuum state, that is, the vacuum degree reached the preset value, the vacuum gauge 12 sent an electrical signal to the control panel 13. The control panel 13 closed the vacuum pump and the air valve 14 on the first air pipe 15 and started the electric guide rail 802. The electric guide rail 802 drove the movable plate 801 to move downward, thereby separating the heat insulation layer 8 from the movable plate 801. The electric guide rail 802 was closed and the heating plate 9 was started. The heating plate 9 gradually raised the temperature inside the chamber 1 to the second preset temperature, that is, the sublimation temperature of water in a vacuum state. The moisture inside and outside the cordyceps sublimated into a gaseous state. Then, the air valves 14 on the first air pipe 15 and the second air pipe 16 were opened and the vacuum pump was started. An air pump and a gas pump are used. The gas pump delivers gas into the chamber 1 at the same power as the vacuum pump. Water vapor in the chamber 1 is extracted by the vacuum pump along with the gas. The vacuum gauge 12 continuously monitors the gas pressure in the chamber 1. When the vacuum level remains stable for a period of time and no longer drops significantly, it indicates that the water has sublimated completely, that is, no new water vapor is generated and extracted. At this time, the vacuum gauge 12 turns off the vacuum pump, the gas pump and the heating plate 9 through the control panel 13. Then the operator opens the chamber door 3 and takes out the dried cordyceps.
