Technical Field
[0001] This utility model relates to the field of mushroom stick sterilization technology, and more specifically to an integrated device for rapid sterilization and cooling of edible mushroom sticks. Background Technology
[0002] Edible fungi refer to large, edible mushrooms (macrofungi), commonly known as mushrooms. China has nearly 950 known species of edible fungi, most of which belong to the Basidiomycota subphylum. Common edible fungi include: shiitake mushrooms, straw mushrooms, button mushrooms, wood ear mushrooms, silver ear mushrooms, monkey head mushrooms, bamboo fungus, matsutake mushrooms, button mushrooms, red mushrooms, reishi mushrooms, cordyceps, truffles, white lingzhi mushrooms, and porcini mushrooms; a few belong to the Ascomycota subphylum, including: morels, saddle mushrooms, and truffles. These fungi grow in different regions and ecological environments, making sterilization a crucial step in edible fungi production.
[0003] A search revealed a sterilizer for sterilizing mushroom spawn (publication number CN220776785U). The sterilizer includes a main body and a mushroom spawn sterilization mesh cage inserted into the upper part of the main body's inner cavity. The mesh cage consists of a cage body inserted into the upper part of the main body's inner cavity. Mushroom spawn support frames are fixedly mounted at both the upper and lower ends of the mesh cage body's inner cavity. A pull-out handle structure is symmetrically mounted on the front and rear sides of the upper edge of the mesh cage body. The mushroom spawn sterilization mesh cage is used to insert and place mushroom spawn, facilitating the insertion and removal of the spawn into the main body of the steam sterilizer. The pull-out handle structure allows for easy manipulation of the spawn by pulling the upper end of the pull-out handle structure upwards while wearing heat-resistant gloves, extending it out of the main body of the steam sterilizer. This provides sufficient space to grip the curved handle, improving safety in practical applications.
[0004] Existing methods for sterilizing mushroom spawn mainly employ high-temperature steam disinfection, which requires prolonged heating and consumes a large amount of energy. Furthermore, it cannot achieve uniform and rapid sterilization of the spawn, and the cooling time is also long, thus reducing the sterilization efficiency of the spawn. Based on this, this utility model designs an integrated device for rapid sterilization and cooling of edible mushroom spawn to solve the above problems. Utility Model Content

[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This utility model uses a motor to drive a rotating shaft to rotate, which in turn drives several rotating rods to rotate, thereby driving a rotating drum and a smooth rod to rotate. This means that the mushroom sticks between the rotating drums rotate. The heating rod heats the mushroom sticks and conducts the heat through the rotating drum to the outer wall of the mushroom sticks. Combined with an ultraviolet lamp assembly, the mushroom sticks are rapidly disinfected and sterilized at high temperatures. Because the mushroom sticks rotate continuously, the irradiation and heating of the mushroom sticks are more uniform, thereby improving the disinfection and sterilization efficiency. Compared with traditional high-pressure steam sterilization, which requires a long preparation time and consumes a lot of energy, the disinfection and sterilization of the heating rod and ultraviolet lamp assembly effectively saves resources and is more efficient.

It exchanges heat with the dry air in the box, evaporates into the air carrying heat, and the water dripping into the water tank is recycled, effectively saving resources. The exhaust fan exhausts the hot and humid air out of the box to prevent backflow, thereby achieving rapid cooling of the temperature inside the box. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The integrated device for rapid sterilization and cooling of edible mushroom sticks involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Reference Figures 1-5This utility model provides an integrated device for rapid sterilization and cooling of edible mushroom spawn, including a box body 1. The outer wall of the box body 1 has a movable door 5. Inside the box body 1 are several rotating drums 13, arranged equidistantly in a horizontal direction. Only one spawn is placed in the gap between two rotating drums 13. Heating rods 12 are installed inside each rotating drum 13. Several through holes 19 are provided on the outer wall of each rotating drum 13. Temperature sensors 8 are installed on the inner wall of the box body 1 corresponding to the heating rods 12. The temperature sensors 8 can monitor the temperature changes inside the box body 1 in real time. A PLC controller 4 adjusts the temperature of the heating rods 12 in real time to ensure continuous and stable sterilization of the spawn. A motor 3 is fixedly installed on the outer wall of the box body 1. A rotating shaft 16 is fixedly connected to the output end of the motor 3. The outer wall of the rotating shaft 16... A transmission mechanism 18 is provided, and a rotating shaft 16 synchronously drives several rotating rods 17 to rotate through the transmission mechanism 18. A protective shell 15 is fixedly connected to one side of the inner wall of the housing 1 corresponding to the transmission mechanism 18. The rotating shaft 16 and the rotating rods 17 both penetrate the outer wall of the protective shell 15 and are rotatably connected to it. The transmission mechanism 18 includes sprockets 181 fixedly connected to the outer walls of the rotating shaft 16 and the rotating rods 17. A chain 182 is sleeved between the sprockets 181. A rotating cylinder 13 is fixedly connected to the ends of the rotating rods 17 and the rotating shaft 16. A smooth rod 14 is fixedly connected to the other end of the rotating cylinder 13. The smooth rod 14 and the rotating rods 17 are rotatably connected to the inner wall of the housing 1. The rotating cylinder 13 is made of copper and has through holes 19 to improve heat conduction efficiency. The motor 3 drives the rotating shaft 16 to rotate and drives several rotating rods through the chain 182. The rotating cylinder 17 drives the rotating drum 13 and the light rod 14 to rotate, thus rotating the mushroom sticks between the rotating drum 13. The heating rod 12 heats the mushroom sticks and conducts the heat through the rotating drum 13 to the outer wall of the mushroom sticks. In conjunction with the ultraviolet lamp group 9, the mushroom sticks are rapidly disinfected and sterilized at high temperature. Because the mushroom sticks rotate continuously, the irradiation and heating of the mushroom sticks are more uniform, thereby improving the disinfection and sterilization efficiency. Compared with traditional high-pressure steam sterilization, which requires a long preparation time and consumes a lot of energy, the disinfection and sterilization of the heating rod 12 and the ultraviolet lamp group 9 effectively saves resources and is more efficient. The ultraviolet lamp group 9 is installed on the upper side of the inner wall of the chamber 1 corresponding to the rotating drum 13. An exhaust fan 2 is installed through the top of the chamber 1. A PLC controller 4 is installed on the outer wall of the chamber 1. The PLC controller 4 and the exhaust fan are connected. 2. The motor 3, heating rod 12, ultraviolet lamp group 9 and temperature sensor 8 are electrically connected. The outer wall of the box 1 is penetrated by a water inlet pipe 6 and fixedly connected to it. Several nozzles 11 are connected to the bottom of the water inlet pipe 6. A water tank 10 is provided at the bottom of the box 1. A drain pipe 7 is connected to the bottom of the water tank 10. The water inlet pipe 6 is fixedly connected to the inner wall of the water tank 10. After disinfection and sterilization, cold water for cooling is injected into the box 1 through the water inlet pipe 6 and sprayed downward through the nozzles 11. It exchanges heat with the dry air in the box 1, evaporates into the air with heat, and the water dripping into the water tank 10 is recycled, effectively saving resources. The hot and humid air is discharged from the box 1 by the exhaust fan 2 to prevent backflow, thereby achieving rapid cooling of the temperature inside the box 1.
[0023] The working principle of this invention is as follows: The mushroom sticks to be sterilized are placed between rotating drums 13, with only one mushroom stick placed in the gap between two rotating drums 13. Motor 3 drives rotating shaft 16 to rotate, which in turn drives several rotating rods 17 via chain 182. This, in turn, drives rotating drums 13 and the bare rods 14 to rotate, thus rotating the mushroom sticks between the drums 13. Heating rod 12 heats the mushroom sticks, which are then conducted to the outer wall of the drums 13. Combined with ultraviolet lamp group 9, this achieves rapid high-temperature sterilization and disinfection of the mushroom sticks. Furthermore, the continuous rotation of the mushroom sticks ensures more uniform irradiation and heating, thereby improving the sterilization efficiency. Compared to traditional high-pressure steam sterilization, which requires a long preparation time and consumes a large amount of energy, this method significantly improves the efficiency of sterilization. The disinfection and sterilization of the heating rod 12 and the ultraviolet lamp group 9 effectively saves resources and is more efficient. The temperature sensor 8 can monitor the temperature change inside the chamber 1 in real time. The temperature of the heating rod 12 is adjusted in real time by the PLC controller 4 to ensure the continuous and stable disinfection and sterilization of the mushroom sticks. After disinfection and sterilization, cold water for cooling is injected into the chamber 1 through the water inlet pipe 6 and sprayed downward through the nozzle 11. It exchanges heat with the dry air in the chamber 1, evaporates into the air with heat, and drips into the water tank 10 for continued recycling, effectively saving resources. The hot and humid air is discharged from the chamber 1 by the exhaust fan 2 to prevent backflow, thereby achieving rapid cooling of the temperature inside the chamber 1.
