Description

Technical Field

[0001] This utility model relates to the field of edible fungi processing technology, specifically to a steam-heated sterilization cabinet for edible fungi culture media. Background Technology

[0002] Before inoculating edible fungi culture media with spawn, high-temperature sterilization is required to ensure that the edible fungi grow in a sterile environment. Currently, the sterilization of edible fungi culture media is generally carried out using a high-temperature sterilization cabinet.

[0003] In the prior art, patent application CN202121722717.9 discloses a high-temperature sterilization device for edible fungi culture medium. By incorporating a drying component, it offers the advantages of rapid cooling and drying of the edible fungi culture medium, solving the problem that existing high-temperature sterilization cabinets cannot quickly cool or dry the surface of the culture medium after sterilization before removal. However, this technical solution uses steam as a heat source to raise the internal temperature of the sterilization cabinet. The upward movement of the steam causes uneven heating of the edible fungi at the bottom and top, thus affecting their quality.

[0004] To address the aforementioned technical problems, patent application CN202420805828.3 discloses a sterilization cabinet for edible fungi. This cabinet avoids direct contact between water vapor and the fungi from bottom to top, thus preventing uneven heating of the fungi at the bottom and top, which is beneficial for improving the quality of the fungi. Furthermore, it allows for zoned heating of the water, enabling rapid boiling and saving sterilization time. However, in this technical solution, the cabinet lacks a steam circulation mechanism during the steam's movement into the cabinet, resulting in weak steam flow and consequently low sterilization efficiency for the fungi culture medium. Utility Model Content

[0005] The main purpose of this invention is to provide a steam-heated edible fungus sterilization cabinet that facilitates steam circulation within the cabinet and improves the sterilization efficiency of edible fungus culture media.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: A steam-heated sterilization cabinet for edible fungi culture medium includes a cabinet body with a rotatable door on one side. A baffle is fixed to the lower part of the cabinet interior, and a sealing plate is fixed inside the cabinet body below the baffle. A heating chamber is formed between the sealing plate, the baffle, and the cabinet body, and a heating tube is fixed inside the heating chamber. A water inlet is provided at the upper part of the sealing plate, and a detachable and sealed cap is fixed inside the water inlet. Multiple storage components are arranged inside the cabinet body above the baffle. A connecting shell is fixed to the right end of the cabinet body, and a circulation pump is fixed inside the connecting shell. The inlet pipe of the circulation pump is connected to the upper end of the heating chamber, and the outlet pipe of the circulation pump is connected to the interior of the connecting shell. Each cabinet above the storage component has an inlet hole on its right side wall, which connects the inside of the cabinet to the connecting shell. Inside the cabinet, there is a distribution component corresponding to the inlet hole. One end of the distribution component is fixed inside the cabinet, and the other end of the distribution component is connected to the inlet hole. A return shell is fixed on the left side of the cabinet. Each cabinet below the distribution component has an outlet hole on its left side wall, which connects the inside of the cabinet to the return shell. A return hole is provided on the left side wall of the cabinet below the baffle, which connects the heating chamber to the inside of the return shell. A drain hole is provided on the left side wall of the cabinet, which connects the cabinet part above the baffle to the return hole.

[0007] Specifically, the left end of the upper surface of the baffle plate is inclined downward, the drain hole is inverted L-shaped, and the lower end of the drain hole inlet is flush with the left end of the upper surface of the baffle plate.

[0008] Specifically, the lower left end of the top panel of the cabinet is inclined downward.

[0009] Specifically, the storage component includes baffles fixed to the left and right inner walls of the cabinet respectively, a filter plate is installed inside the cabinet above the two baffles, the baffles block the filter plate, and a placement frame is placed on the upper part of the filter plate.

[0010] Specifically, the lower left end of the filter plate is inclined downwards.

[0011] Specifically, a rectangular groove is provided on the bottom plate of the placement frame, and a filter screen is fixed in the rectangular groove.

[0012] Specifically, the distribution component includes an inner tube, the left end of which is fixedly connected to the inner wall on the left side of the cabinet, the right end of which is connected to the inlet hole, and multiple branch pipes are evenly distributed and fixedly connected on the front and rear sides of the inner tube along the axial direction of the inner tube. The branch pipes are perpendicular to the inner tube, and multiple nozzles are fixed at the lower end of the branch pipes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through a circulation system consisting of a circulating pump, a connecting shell, and a distribution assembly, steam is evenly sprayed onto the surface of the culture medium within the placement frame, avoiding localized overheating or dead zones. The steam circulates between the cabinet, the return shell, and the heating chamber, improving sterilization efficiency (reducing energy waste) and ensuring a rapid and uniform sterilization process.

[0014] 2. The filter screen design on the bottom plate of the placement frame prevents condensate from accumulating inside the frame, facilitating water drainage. Simultaneously, the filter plate supports the placement frame, further aiding drainage. The inclined design of the lower end face of the cabinet top plate, the upper end face of the baffle, and the lower end face of the filter plate guides condensate to the left, reducing the amount entering the placement frame, lowering the moisture content of the culture medium after sterilization, and facilitating subsequent drying operations.

[0015] 3. The left end of the upper surface of the baffle slopes downwards, and the drain hole is inverted L-shaped. The lower end of the drain hole inlet is flush with the left end of the upper surface of the baffle, allowing the condensate in the cabinet to flow naturally into the water storage chamber and automatically return to the heating chamber through the return hole. This not only replenishes the heating water and reduces the frequency of manual water addition, but also accelerates the condensate return through steam flow, improving the system's sustainability.

[0016] 4. The overall design simplifies the operation process, allowing for quick placement of culture medium, addition of water, and equipment startup. Storage components are easy to disassemble and clean, improving the equipment's usability and maintenance efficiency.

[0017] 5. The combined action of steam circulation and condensate management mechanisms reduces temperature fluctuations and moisture interference during sterilization, ensuring a higher sterilization rate for the culture medium. The inclined design of the lower end face of the cabinet top plate, the upper end face of the baffle, and the lower end face of the filter plate further reduces the impact of condensate on the sterilization effect, enhancing the stability and reliability of the equipment during continuous operation.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1: Refer to Figures 1-8 As shown, a steam-heated sterilization cabinet for edible fungi culture medium includes a cabinet body 1, and a cabinet door 2 is rotatably installed on one side of the cabinet body 1.

[0029] A baffle 11 is fixed at the lower end of the cabinet 1. A sealing plate 10 is fixed inside the cabinet 1 below the baffle 11. A heating chamber 21 is formed between the sealing plate 10, the baffle 11 and the cabinet 1. A heating tube 17 is fixed inside the heating chamber 21. A water inlet 12 is opened at the upper end of the sealing plate 10. A sealing cover is detachably fixed and sealed inside the water inlet 12.

[0030] Multiple storage components are installed inside the cabinet 1 above the baffle 11.

[0031] The storage component includes baffles 3 fixed to the left and right inner walls of the cabinet 1 respectively. A filter plate 4 is installed inside the cabinet 1 above the two baffles 3. The baffles 3 block the filter plate 4. A placement frame 5 is placed on the upper end of the filter plate 4.

[0032] A rectangular groove is provided on the bottom plate of the placement frame 5, and a filter screen 20 is fixed in the rectangular groove.

[0033] A connecting shell 9 is fixed to the right end of the cabinet 1. A circulation pump 18 is fixed inside the connecting shell 9. The inlet pipe of the circulation pump 18 is connected to the upper end of the heating chamber 21, and the outlet pipe of the circulation pump 18 is connected to the inside of the connecting shell 9.

[0034] An inlet hole 19 is provided on the right side wall of the cabinet 1 above the storage component. The inlet hole 19 connects the inside of the cabinet 1 and the connecting shell 9. A distribution component corresponding to the inlet hole 19 is provided inside the cabinet 1. One end of the distribution component is fixed inside the cabinet 1, and the other end of the distribution component is connected to the inlet hole 19.

[0035] The distribution assembly includes an inner tube 6. The left end of the inner tube 6 is fixedly connected to the inner wall on the left side of the cabinet 1. The right end of the inner tube 6 is connected to the inlet hole 19. Multiple branch pipes 7 are evenly distributed and fixedly connected on the front and rear sides of the inner tube 6 along the axial direction of the inner tube 6. The branch pipes 7 are perpendicular to the inner tube 6. Multiple nozzles 8 are fixed at the lower end of the branch pipes 7.

[0036] A return shell 13 is fixed on the left side of the cabinet 1. An outlet hole 14 is opened on the left side wall of the cabinet 1 below the distribution component. The outlet hole 14 connects the inside of the cabinet 1 and the return shell 13. A return hole 15 is opened on the left side wall of the cabinet 1 below the baffle 11, which connects the heating chamber 21 and the inside of the return shell 13. A drain hole 16 is opened on the left side wall of the cabinet 1, which connects the part of the cabinet 1 above the baffle 11 and the return hole 15.

[0037] When sterilizing the culture medium for edible fungi, the culture medium is placed in multiple placement frames 5, and then the placement frames 5 containing the culture medium are placed on the filter plate 4.

[0038] Remove the cap inside the water inlet 12 and add water to the heating chamber 21. Then close the cabinet door 2. At this time, the cabinet door 2 is in sealed contact with the front end of the baffle 11, and a water storage chamber 22 is formed between the bottommost storage component, the cabinet door 2, the cabinet body 1 and the baffle 11.

[0039] Heating tube 17 is activated, heating the water in heating chamber 21 to generate steam. Then, circulation pump 18 is activated, and the steam in heating chamber 21 is transported to connecting shell 9. The steam entering connecting shell 9 is ejected through inlet 19, inner pipe 6, branch pipe 7, and nozzle 8, and comes into contact with the culture medium in placement frame 5, thereby sterilizing the culture medium in placement frame 5. After circulation pump 18 is activated, the steam in cabinet 1 re-enters heating chamber 21 through outlet 14, return shell 13, and reflux hole 15 for secondary heating. The steam can circulate in connecting shell 9, cabinet 1, return shell 13, and heating chamber 21, which can improve the sterilization efficiency of the culture medium.

[0040] Steam is ejected from multiple nozzles 8 at the lower end of the branch pipe 7, which can make the steam evenly distributed at the upper end of the placement frame 5, thereby improving the sterilization rate of the culture medium in the placement frame 5.

[0041] The filter plate 4 supports the placement frame 5. The bottom plate of the placement frame 5 is equipped with a filter screen 20, which can prevent condensate from accumulating in the placement frame 5 and facilitate the drainage of condensate in the placement frame 5.

[0042] Example 2: Based on Example 1, referring to... Figure 1 and Figure 3As shown, the lower left end of the top panel of cabinet 1 slopes downwards. The upper left end of baffle 11 slopes downwards. The drain hole 16 is inverted L-shaped, and the lower end of the drain hole 16 inlet is flush with the left end of the upper surface of baffle 11. The lower left end of the filter plate 4 slopes downwards.

[0043] In this embodiment, the condensate on the vertical side wall inside the cabinet 1 can flow downward and be received by the upper end of the baffle 11 before flowing into the water storage chamber 22. Since the left end of the upper surface of the baffle 11 is inclined downward, the condensate in the water storage chamber 22 can easily flow back into the heating chamber 21 through the drain hole 16 and the return hole 15, thereby replenishing the water in the heating chamber 21.

[0044] As steam flows through the return hole 15, it can accelerate the flow of water in the water storage chamber 22 to the heating chamber 21 through the drain hole 16 and the return hole 15.

[0045] The lower left end of the top plate of cabinet 1 and the lower left end of the filter plate 4 are inclined downwards. Therefore, the condensate at the lower end of the top plate of cabinet 1 and the condensate at the lower end of the filter plate 4 can flow and accumulate to the left, which can reduce the amount of condensate entering the placement frame 5 and facilitate the subsequent drying of the culture medium.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
