Edible mushroom sterilization box condensate water flow guide structure

Abstract

A condensate drainage structure for an edible mushroom sterilization box includes an anti-condensation sterilization box, a drainage component, and a placement rack. The anti-condensation sterilization box has an upright four-sided pyramidal structure for its lid and bottom, and its four walls are a double-layered structure with a vacuum insulation cavity. The inner surfaces of the four walls are each provided with a hydrophobic layer. Multiple placement racks with mesh plates are evenly spaced inside the anti-condensation sterilization box. A number of inclined drainage units and vertically positioned aluminum foil composite aluminum silicate tubing at the four corners of the box are pre-installed. This structure enables the shortest path for condensate recovery and minimizes contact between condensate and steam. The water collection pipe and steam generator recycle and reuse the condensate. The diffusion cavity of the steam distribution component creates a pressure-stabilizing space near the steam inlet, preventing excessive local pressure. This effectively solves problems such as the inability to use an anti-condensation sterilization box and the inability to use the drainage component.

Description

Technical Field

[0001] This utility model relates to the field of edible fungi production equipment technology, and in particular to a condensate drainage structure for an edible fungi sterilization box. Background Technology

[0002] In the sterilization process of edible fungi, the common sterilization method is to use high-temperature steam to deactivate the proteins of the fungi, thereby achieving the purpose of sterilization. However, during the high-temperature steam sterilization process, the steam will condense when it encounters cold. If it is not discharged in time, the condensate will drip onto the culture medium or fungal bag, leading to the risk of microbial contamination, which in turn affects the growth quality of the strain and the sterilization effect. However, existing condensate drainage devices for edible mushroom sterilization chambers cannot achieve the goal of using an anti-condensation sterilization chamber. They cannot simultaneously utilize three anti-condensation designs: the scientifically angled lid for drainage, the vacuum insulation chamber to prevent the conduction and convection of cold air from the outside into the sterilization chamber, and the hydrophobic layer on the inner wall of the sterilization chamber that "prevents adhesion, promotes drainage, inhibits contamination, and ensures quality." Therefore, they cannot minimize condensate generation within the sterilization chamber, cannot utilize drainage components, cannot ensure the shortest path for condensate recovery, cannot recover condensate into the heat-insulating aluminum foil composite aluminum silicate sleeve within the sterilization chamber, and cannot effectively reduce contact between condensate and steam, causing localized temperature changes within the sterilization chamber and thus affecting the sterilization effect of the edible mushrooms.

[0003] Patent No. ZL201920931409.3 discloses a "sterilization device for oyster mushroom culture medium." This utility model includes a sterilization device body comprising a high-pressure sterilization chamber, a preheating water tank, and an electric steam generator. The high-pressure sterilization chamber includes, from the inside out, an inner liner, a first gap, a sandwich layer, a second gap, and a heat-insulating outer layer. The sidewall of the inner liner has several evenly distributed steam holes. An exhaust pipe connected to the interior of the preheating water tank is located on the sidewall of the inner liner, and a safety valve is installed on the exhaust pipe. The outer wall of the heat-insulating outer layer also has a steam inlet connected to the interior of the first gap. The outer wall of the preheating water tank has a first water inlet and a water outlet. The electric steam generator has a second water inlet connected to the water outlet and a steam outlet connected to the steam inlet. This utility model has a reasonable structural design, good sterilization effect, and low operating cost, which is conducive to its market promotion and application.

[0004] Patent No. ZL202422088334.0 discloses a "high-efficiency and energy-saving sterilization equipment for soybean products." This utility model addresses the problems of existing methods where a water guide plate at the bottom of the tray affects the sterilization operation of the water vapor on the sample below, and the dripping water affects the sample below. Furthermore, the collected water is directly discharged, carrying away a large amount of heat. The proposed solution includes a sterilization chamber equipped with a steam generator for producing sterilizing water vapor. The sterilization chamber has an internal cavity for providing saturated sterilizing steam. A frame is placed inside the cavity, and multiple trays are placed on the frame. The samples to be sterilized are placed on the trays. Distribution cavities at the same height as the frame are provided on both sides of the cavity. This application eliminates dead zones during sterilization, and the condensed water dripping down collects and flows to the bottom recovery tank, not affecting the sample below. The condensed water in the recovery tank, still carrying heat, can be recycled, making it more energy-efficient and environmentally friendly. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides a condensate drainage structure for an edible mushroom sterilization chamber. It includes an anti-condensation sterilization chamber, drainage components, and a water collection pipe, achieving the simultaneous use of three anti-condensation designs: scientifically guiding the flow using the tilted angle of the chamber lid, isolating the conduction and convection of external cold air into the sterilization chamber using a vacuum insulation cavity, and employing a hydrophobic layer on the inner wall of the sterilization chamber that "prevents adhesion, promotes drainage, inhibits contamination, and ensures quality." This minimizes the generation of condensate within the sterilization chamber and ensures that the condensate is recovered via the shortest path. The condensate is then collected within the heat-insulating aluminum foil composite aluminum silicate sleeve, effectively reducing contact between the condensate and steam, thus minimizing localized temperature changes within the sterilization chamber and consequently affecting the sterilization effect of the edible mushrooms. This effectively solves the aforementioned technical problems.

The door is hinged to the front of the anti-condensation sterilization chamber and is a double-opening structure. The size of the door matches the size of the front face of the anti-condensation sterilization chamber. A sealing component is provided at the corresponding position of the door and the anti-condensation sterilization chamber. The lid, bottom, side walls, and door are all configured as sealed double-layer structures, with the inner cavity of the double-layer structure being a vacuum insulation cavity. A hydrophobic layer is provided on the inner surfaces of the lid, bottom, side walls, and door. The placement rack is configured as a frame structure consisting of two support rods and a predetermined number of equidistant horizontal bars. A grid plate is provided at the upper end of the placement rack. The two ends of the placement rack are horizontally fixed to the inner walls of the left and right sides of the anti-condensation sterilization box by fasteners. The placement rack is configured in a predetermined number, and the predetermined number of placement racks are arranged at equal intervals from top to bottom.

[0007] The flow guiding assembly includes flow guiding units and flow guiding pipes. The flow guiding unit includes two flow guiding plates, which are arranged end-to-end with both ends symmetrically inclined downwards at a preset angle. A preset number of flow guiding units are fixedly installed on the three side walls and the door of the anti-condensation sterilization chamber. The preset number of flow guiding units are arranged in an orderly manner from top to bottom. The inclination angle of the flow guiding plate is set to a preset angle. The flow guiding plate is set to an inward inclined structure. The flow guiding pipe is set to an aluminum foil composite aluminum silicate sleeve structure. The flow guiding pipe is vertically installed at the four corners inside the anti-condensation sterilization chamber. The flow guiding pipe has a preset number of through holes I. The port of each through hole I is provided with a one-way membrane. Each through hole I is connected to the outer end of the corresponding flow guiding plate. The number and position of the through holes I match the number and position of the flow guiding plates. The upper port of the flow guiding pipe is set to a sealed structure.

[0008] It also includes a water collection pipe, which is located at the lower end of the three side walls inside the anti-condensation sterilization chamber. The water collection pipe has four through holes II, which are located at matching positions on the water collection pipe. The lower end of the guide pipe is connected to the water collection pipe through the through holes II. A return port is provided at a preset position on the water collection pipe. The water collection pipe is designed with an inclined structure, and the return port is located at the lowest point of the water collection pipe.

[0009] It also includes a steam generator, which is located outside the anti-condensation sterilization chamber.

[0010] It also includes a steam distribution component, which includes a diffusion chamber. The diffusion chamber is fixed in the middle of the inner walls on both sides of the anti-condensation sterilization chamber by a fixing member. The diffusion chamber has an air inlet facing outward. The two air inlets are connected to the steam outlet of the steam output unit through a tee and a pipe. The diffusion chamber has a preset number of orderly arranged strip slits facing inward. The bottom of the diffusion chamber has a drain outlet, which is connected to a guide pipe through a hose.

[0011] The beneficial effects of this utility model are: This invention features an anti-condensation sterilization chamber that utilizes three anti-condensation designs simultaneously: a tilted lid for scientific airflow guidance, a vacuum insulation chamber to prevent the conduction and convection of cold air from the outside into the chamber, and a hydrophobic layer on the inner wall of the chamber that prevents adhesion, promotes airflow, inhibits contamination, and ensures quality. This design minimizes condensation within the sterilization chamber and effectively solves the problem of not being able to use an anti-condensation sterilization chamber or not being able to simultaneously utilize all three anti-condensation designs to minimize condensation.

[0012] This invention incorporates a flow guiding component and a corresponding water collection pipe, ensuring that condensate is recovered along the shortest path. Within the sterilization chamber, the condensate is collected into an insulated aluminum foil composite aluminum silicate sleeve, effectively reducing contact between the condensate and steam, thus minimizing localized temperature fluctuations within the sterilization chamber and consequently affecting the sterilization effect of edible fungi. This invention effectively solves the problems associated with not using a flow guiding component, ensuring the shortest path for condensate recovery, and preventing the collection of condensate into the insulated aluminum foil composite aluminum silicate sleeve within the sterilization chamber, thus failing to effectively reduce contact between the condensate and steam and causing localized temperature fluctuations within the sterilization chamber, ultimately impacting the sterilization effect of edible fungi.

[0020] The enoki mushroom cultivation and production enterprise uses the aforementioned condensate drainage structure of the edible fungus sterilization box. The anti-condensation sterilization box 1 is placed on a stable workbench. Following the installation instructions, all equipment is assembled securely. All pipes and hoses are sealed and connected to the steam generator 19. The steam generator 19 is connected to the mains power via a cable. After checking that all equipment is functioning correctly, the door 7 of the anti-condensation sterilization box 1 is opened. The enoki mushroom spawn bags are neatly and evenly placed on the rack 3 equipped with the grid plate 10. The door 7 is closed, ensuring a good seal. The steam generator 19 is then turned on. The control unit sets the required data such as output steam temperature and flow rate. Press the start button of steam generator 19, and steam generator 19 starts to work. Steam is output from the steam outlet of steam output unit. Steam enters two diffusion chambers 21 through tee, pipe and air inlet. A pressure stabilizing space is formed inside diffusion chamber 21. After the steam pressure is equalized, it is slowly released and diffused into the box through strip slit 22 to avoid turbulence and condensate accumulation caused by excessive local pressure near steam inlet. Condensate flows along the inner wall of diffusion chamber 21 to drain port 23 at the bottom of the chamber and flows into guide pipe 12 through hose. The lid 4 is designed as an upright four-sided pyramid structure, which can scientifically guide the airflow using an inclined angle. The lid 4, bottom 5, side wall 6 and door 7 are all equipped with sealed vacuum insulation chambers 8, which can isolate the conduction and convection of cold air from the outside into the anti-condensation sterilization chamber 1. The inner surfaces of the lid 4, bottom 5, side wall 6 and door 7 are all equipped with hydrophobic layers 9, which can reduce the adhesion of condensate, accelerate the rolling off of water droplets, inhibit the growth of microorganisms and ensure sterilization quality. At the same time, the combined use of the above three anti-condensation designs can minimize the generation of condensate in the anti-condensation sterilization chamber 1. The lid 4, side wall 6, and door 7 are each equipped with a predetermined number of flow guiding units 11 from top to bottom. Each flow guiding unit 11 consists of two flow guiding plates 13 connected end to end and symmetrically inclined downwards at predetermined angles. This structure allows for the shortest path to recover the corresponding condensate into the flow guiding pipe 12. The flow guiding pipes 12 at the four corners inside the anti-condensation sterilization chamber 1 are designed as aluminum foil composite aluminum silicate sleeves, which effectively reduce the contact between condensate and steam and prevent local temperature changes in the anti-condensation sterilization chamber 1, thus affecting the sterilization effect of edible fungi. The flow guiding plates 13 are inclined inwards to prevent condensate from overflowing during the flow guiding process. The port of the through hole I 14 is equipped with a one-way membrane 15 to prevent condensate from flowing back. The condensate at the bottom 5 is guided to the four corners of the bottom of the anti-condensation sterilization chamber 1 and enters the flow guiding pipe 12 from the corresponding one-way membrane 15. The condensate from the four corner guide pipes 12 is collected in the water collection pipe 16 and introduced into the water tank of the steam generator 19 water supply unit through the return port 18 and a hose for recycling, further saving resources. At this point, the sterilization process of the enoki mushroom spawn bag using the condensate guide structure of the edible mushroom sterilization box is completed.
