[0014] Further, a wing plate is arranged on the side wall of the condensation plate, and the condensation plate is rotated by the wing plate when air is discharged from the air exhaust pipe.

[0015] Further, a backflow assembly is arranged on the support frame, the backflow assembly comprises a funnel fixed to the support frame, a backflow pipe is arranged at the outlet of the funnel, and the backflow pipe is communicated with the purification barrel.

[0016] The application also provides a method for preventing the migration of plasticizers into spore powder during the growth of ganoderma, comprising the following steps:

[0017] S1, preparing culture material, wrapping the culture material with a layer of fungus bag, and placing a layer of tin foil paper between the fungus bag and the culture material to prevent the migration of plasticizers; placing the culture material in a sterilization pot, sterilizing the culture material under the condition of 1.5 kg / cm 2 for 1.5-2 hours; inoculating the culture material under sterile conditions after sterilization; placing the inoculated fungus bag in a greenhouse, covering a layer of mulch above the fungus bag, controlling the temperature at 22-30 DEG C, preferably 24-28 DEG C, storing in the dark, paying attention to ventilation and cooling, checking once a week, discarding the contaminated fungus bag, and allowing the mycelium to grow full in about 10 days; and opening the air suction machine in the device to purify the air in the greenhouse 2-3 days before placing the fungus bag in the greenhouse.

[0018] S2. When the mycelium has grown for about 30 days and buds form on the surface, open the bag to allow the Ganoderma lucidum to grow outwards. The buds will extend outwards to form a stipe. The cap will grow on the stipe in about 15 days. It will mature in 30 to 50 days, and the spores will be released from the cap. It can then be harvested. During this stage, ventilation and water spraying into the air should be taken. The temperature should be controlled at 24 to 28°C and the relative humidity should be 90% to 95%. Keep the air fresh and use diffused light. When spraying water, make sure to use plasticizer-free metal pipes for water delivery.

[0019] S3. After the Ganoderma lucidum matures, its fruiting body begins to release spores. A layer of food-grade paper is laid on the mulch to isolate plasticizers and prevent the spores from being contaminated by plasticizers during collection.

[0020] S4. Spread the collected spore powder evenly on clean, smooth paper and place it in a well-ventilated, sunny place to dry. The entire process from inoculation to drying of the spore powder is carried out in an environment free of plasticizers.

[0021] Compared with existing technologies, the advantages of this invention are:

[0022] 1. In this invention, aluminum foil is placed between the spawn bag and the culture medium during the cultivation of the spawn to prevent the migration of plasticizers. The air in the greenhouse is purified 2-3 days before the spawn bags are moved into the greenhouse to remove plasticizers from the air. The water pipes used for irrigation of Ganoderma lucidum are metal pipes to prevent plasticizers in the air and water from migrating into the Ganoderma lucidum during its growth. Paper is laid on the spores during collection and drying. The entire process from spawn inoculation to spore drying is carried out in a plasticizer-free environment, which can effectively prevent plasticizers from migrating into the spores.

[0023] 2. This invention uses a jet pipe and a suction fan to draw air from the greenhouse into a purification tank for purification. When the air is ejected from the jet pipe, it drives the air delivery pipe to rotate, thereby moving the trolley. While purifying the air, the trolley continuously moves its position, improving the purification effect. It cleverly utilizes the reaction force received when the jet pipe is ejected to drive the air delivery pipe to rotate and move the trolley, eliminating the need for an additional motor drive for the trolley and reducing equipment costs.

[0024] 3. This invention, by setting up a jet pipe, stirs the Tween-80 solution in the purification tank when the jet pipe drives the air delivery pipe to rotate, so that the plasticizer is more evenly dispersed in the Tween-80 solution and has better contact with the immobilized thermophilic esterase, thereby improving the efficiency of plasticizer degradation and completely removing plasticizer from the air by promoting the degradation of plasticizer.

[0025] 4. This invention, by setting up a pressurization component, causes the pressurization plate to move up and down repeatedly when the gas delivery pipe rotates. When the pressurization plate moves down, the through hole contacts the buoyancy ball, and the pressurization plate continues to push the buoyancy ball down. The pressure below the pressurization plate increases, forcing the air to dissolve in the Tween-80 solution. When the pressurization plate moves up, before the through hole separates from the buoyancy ball, the pressure below the pressurization plate decreases, and the air is released again, generating a large number of microbubbles. By reducing the volume of the bubbles formed after the air enters the solution through the pressurized dissolved gas release method, the air and solution can be contacted more fully, and the plasticizer in the air can be better dissolved into the solution, improving the purification effect of plasticizer.

[0026] 5. By setting up a condensation component and a return component, when the pressure plate moves upward, the through hole separates from the buoyancy ball. The purified air flows through the through hole to the top of the pressure plate and then is discharged from the exhaust pipe to the outside of the purification box. When the air is discharged from the exhaust pipe, it blows towards the condensation plate. The condensation plate liquefies the water vapor carried in the air and then guides it into the purification box through the return pipe for continued use. This avoids the reduction of the solution in the purification box and also avoids changing the air humidity in the greenhouse during air purification.

[0027] 6. By setting up wing plates, when air is blown towards the condenser plate, the wing plates drive the condenser plate to rotate, so that the air is always blown to different positions on the condenser plate. This avoids the air blowing to the same position on the condenser plate, which would cause the temperature of the condenser plate to rise. This ensures the condenser plate's effect of liquefying water vapor. Furthermore, when the condenser plate rotates, the water droplets on it fall quickly into the funnel under the action of centrifugal force, preventing water droplets from remaining on the condenser plate and affecting the condensation effect.

[0043] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0044] like Figures 1-8 As shown, a device for preventing plasticizers from migrating into Ganoderma lucidum spores during growth includes:

[0045] Cart 1, with guide rail 11 below it, the guide rail 11 is laid along the length of the planting greenhouse;

[0046] Purification tank 2 has a suction fan 21 on top, an air guide pipe 22 on the suction fan 21, a fixing sleeve 221 on the air guide pipe 22, and an air supply pipe 23 between the fixing sleeve 221 and the bottom of purification tank 2. The bottom of the air supply pipe 23 has multiple jet pipes 24 arranged in a circular array. When the suction fan 21 is turned on, it draws in the air from the planting greenhouse and then sprays it out through the jet pipes 24. When the air is sprayed out from the jet pipes 24, it drives the jet pipes 24 and the air supply pipe 23 to rotate around the central axis of the air supply pipe 23. The top of purification tank 2 has an exhaust pipe 25. Purification tank 2 contains Tween-80 solution 26, which contains immobilized thermophilic esterase 27. After the air enters the purification tank 2, it dissolves in the water under the action of Tween-80. The plasticizer in the air is degraded under the action of immobilized thermophilic esterase 27.

[0047] In practice, the suction fan 21 draws air from the greenhouse into the purification tank 2 for purification. The plasticizers in the air dissolve in the water under the action of Tween-80. When the air is sprayed out from the jet pipe 24, it drives the air delivery pipe 23 to rotate and stir the Tween-80 solution 26 in the purification tank 2, so that the plasticizers are more evenly dispersed in the Tween-80 solution 26 and have better contact with the immobilized thermophilic esterase 27. The immobilized thermophilic esterase 27 promotes the degradation of plasticizers, thereby removing plasticizers from the air.

[0048] The bottom end of the gas pipe 23 is provided with a rotating shaft 31 that passes through the trolley 1. A worm gear 32 is provided on the rotating shaft 31. A worm wheel 33 that cooperates with the worm gear 32 is provided on the drive shaft of the trolley 1. By utilizing the speed reduction transmission characteristics of the worm gear 32 and the worm wheel 33, the trolley 1 is driven to move slowly when the gas pipe 23 rotates.

[0049] In actual operation, the rotation of the air supply pipe 23 drives the rotating shaft 31 and the worm gear 32 to rotate, which in turn drives the worm wheel 33 to rotate slowly, causing the trolley 1 to move slowly. While purifying the air, the trolley 1 continuously moves its position to improve the purification effect.

[0050] The purification tank 2 is equipped with a pressurization component, which includes a pressurization plate 4 slidably connected to the side wall of the purification tank 2. The pressurization plate 4 has multiple through holes 41 arranged in a circumferential array. The side wall of the purification tank 2 is equipped with multiple mounting plates 42. In this embodiment, the number of through holes 41 and mounting plates 42 is 8. The mounting plate 42 is equipped with a movable rod 43 that passes through the mounting plate 42. Both ends of the movable rod 43 are equipped with buoyancy balls 44. The diameter of the buoyancy balls 44 is larger than the diameter of the through holes 41. In the natural state, the lower buoyancy balls 44 abut against the mounting plate 42 under the action of buoyancy. The pressurization component also includes a nut 45 fixed above the pressurization plate 4. The gas supply pipe 23 is equipped with a threaded sleeve 46 that is threaded with the nut 45. The thread of the threaded sleeve 46 is a reciprocating thread. When the gas supply pipe 23 rotates, it drives the pressurization plate 4 to move up and down reciprocally.

[0051] In actual operation, when the gas supply pipe 23 rotates, it drives the threaded sleeve 46 to rotate. Under the threaded engagement of the nut 45 and the threaded sleeve 46, the pressure plate 4 moves up and down reciprocally. When the pressure plate 4 moves down, the through hole 41 contacts the buoyancy ball 44, and the pressure plate 4 continues to push the buoyancy ball 44 down. The pressure below the pressure plate 4 increases, forcing the air to dissolve in the Tween-80 solution 26. When the pressure plate 4 moves up, before the through hole 41 separates from the buoyancy ball 44, the pressure below the pressure plate 4 decreases, the air is released again, and a large number of microbubbles are generated. By reducing the volume of the bubbles formed after the air enters the solution through the pressurized dissolved gas release method, the air and solution can be contacted more fully, and the plasticizer in the air can be better dissolved into the solution, improving the purification effect of plasticizer.

[0052] The trolley 1 is equipped with a condensing assembly, which includes a support frame 51 fixed on the trolley 1. The support frame 51 is equipped with a central shaft 52, and the bottom end of the central shaft 52 is equipped with a condensing plate 53. The condensing plate 53 uses semiconductor refrigeration. The condensing plate 53 is frustum-shaped, and the side wall of the condensing plate 53 is equipped with a wing plate 54. When air is discharged from the exhaust pipe 25, the wing plate 54 drives the condensing plate 53 to rotate.

[0053] The support frame 51 is provided with a reflux assembly, which includes a funnel 61 fixed on the support frame 51. The outlet of the funnel 61 is provided with a reflux pipe 62, which is connected to the purification tank 2.

[0054] In actual operation, when the pressure plate 4 moves upward, the through hole 41 separates from the buoyancy ball 44. The purified air flows from the through hole 41 to the top of the pressure plate 4 and then is discharged from the exhaust pipe 25 to the outside of the purification box 2. When the air is discharged from the exhaust pipe 25, it blows towards the condenser plate 53. The condenser plate 53 liquefies the water vapor carried in the air. When the air blows towards the condenser plate 53, it drives the condenser plate 53 to rotate under the action of the wing plate 54, so that the air is always blown to different positions of the condenser plate 53. This avoids the air blowing to the same position of the condenser plate 53, which would cause the temperature of the condenser plate 53 to rise, thus ensuring the condenser plate 53's effect of liquefying water vapor. The rotation of the condenser plate 53 causes the water droplets on it to fall quickly into the funnel 61 under the action of centrifugal force, avoiding the residual water droplets on the condenser plate 53 from affecting the condensation effect. After the water droplets fall into the funnel 61, they are introduced into the purification box 2 through the return pipe 62 for continued use, avoiding the reduction of the solution in the purification box 2 and also avoiding changes in the air humidity in the greenhouse during air purification.

[0055] In this embodiment, all components mentioned in the above-mentioned device are made of materials that do not contain plasticizers.

[0056] like Figure 9 As shown, the present invention also provides a method for preventing plasticizers from migrating into the spore powder during the growth of Ganoderma lucidum, comprising the following steps:

[0057] S1. Prepare the culture medium. Wrap a layer of mushroom bags around the surface of the culture medium, and place a layer of aluminum foil between the mushroom bags and the culture medium to prevent plasticizer migration. Place the culture medium in an autoclave and sterilize at 1.5 kg / cm³. 2 Sterilize for 1.5 to 2 hours under sterile conditions. After sterilization, inoculate under sterile conditions. Place the inoculated bags into the greenhouse and cover them with a layer of mulch. Control the temperature at 22 to 30°C, with the optimal temperature being 24 to 28°C. Store in the dark and ensure ventilation and cooling. Check once a week and discard any contaminated bags. The mycelium will fully colonize the bags in about 10 days. Turn on the air ventilator 21 in the device 2-3 days before placing the bags into the greenhouse to purify the air inside.

[0058] S2. When the mycelium has grown for about 30 days and buds form on the surface, open the bag to allow the Ganoderma lucidum to grow outwards. The buds will extend outwards to form a stipe. The cap will grow on the stipe in about 15 days. It will mature in 30 to 50 days, and the spores will be released from the cap. It can then be harvested. During this stage, ventilation and water spraying into the air should be taken. The temperature should be controlled at 24 to 28°C and the relative humidity should be 90% to 95%. Keep the air fresh and use diffused light. When spraying water, make sure to use plasticizer-free metal pipes for water delivery.

[0059] S3. After the Ganoderma lucidum matures, its fruiting body begins to release spores. A layer of food-grade paper is laid on the mulch to isolate plasticizers and prevent the spores from being contaminated by plasticizers during collection.

[0060] S4. Spread the collected spore powder evenly on clean, smooth paper and place it in a well-ventilated, sunny place to dry. The entire process from inoculation to drying of the spore powder is carried out in an environment free of plasticizers.

[0061] The working principle of this invention is as follows:

[0062] Two to three days before planting Ganoderma lucidum, turn on the suction fan 21. The suction fan 21 draws the air in the greenhouse into the purification tank 2 for purification. The plasticizers in the air dissolve in the water under the action of Tween-80. When the air is sprayed out from the jet pipe 24, it drives the air delivery pipe 23 to rotate and stir the Tween-80 solution 26 in the purification tank 2. This makes the plasticizers more evenly dispersed in the Tween-80 solution 26 and better contact the immobilized thermophilic esterase 27. The immobilized thermophilic esterase 27 promotes the degradation of plasticizers, thereby removing the plasticizers in the air.

[0063] The rotation of the air supply pipe 23 drives the rotating shaft 31 and the worm gear 32 to rotate, thereby driving the worm wheel 33 to rotate slowly and making the trolley 1 move slowly. While purifying the air, the trolley 1 continuously moves its position to improve the purification effect. The reaction force received when the jet pipe sprays air is cleverly used to drive the air supply pipe to rotate and drive the trolley to move. There is no need to add an extra motor drive for the trolley, which reduces the equipment cost.

[0064] When the gas pipe 23 rotates, the threaded sleeve 46 rotates. Under the action of the threaded engagement of the nut 45 and the threaded sleeve 46, the pressure plate 4 moves up and down reciprocally. When the pressure plate 4 moves down, the through hole 41 contacts the buoyancy ball 44. The pressure plate 4 continues to push the buoyancy ball 44 down. The pressure below the pressure plate 4 increases, forcing the air to dissolve in the Tween-80 solution 26. When the pressure plate 4 moves up, before the through hole 41 separates from the buoyancy ball 44, the pressure below the pressure plate 4 decreases, the air is released again, and a large number of microbubbles are generated. By reducing the volume of the bubbles formed after the air enters the solution through the pressurized dissolved gas release method, the air and solution can be contacted more fully, and the plasticizer in the air can be better dissolved in the solution, improving the purification effect of the plasticizer.

[0065] When the pressure plate 4 moves upward, the through hole 41 separates from the buoyancy ball 44. The purified air flows from the through hole 41 to the top of the pressure plate 4 and then is discharged from the exhaust pipe 25 to the outside of the purification box 2. When the air is discharged from the exhaust pipe 25, it blows towards the condenser plate 53. The condenser plate 53 liquefies the water vapor carried in the air. When the air blows towards the condenser plate 53, it drives the condenser plate 53 to rotate under the action of the wing plate 54, so that the air is always blown to different positions of the condenser plate 53. This avoids the air blowing to the same position of the condenser plate 53, which would cause the temperature of the condenser plate 53 to rise. This ensures the condenser plate 53's effect of liquefying water vapor. The rotation of the condenser plate 53 causes the water droplets on it to fall quickly into the funnel 61 under the action of centrifugal force, avoiding the water droplets remaining on the condenser plate 53 from affecting the condensation effect. After the water droplets fall into the funnel 61, they are introduced into the purification box 2 through the return pipe 62 for continued use. This avoids the solution in the purification box 2 from decreasing and also avoids changing the air humidity in the greenhouse when purifying the air.

[0066] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

When the mycelium grows for 30 days and buds form on the surface, open the bag to allow the Ganoderma lucidum to grow outward. The buds extend outward to form a stipe. After 15 days, a cap grows on the stipe. After 30-50 days, it matures and the spores are released from the cap, at which point it can be harvested. During this stage, ventilation and water spraying into the air should be taken. The temperature should be controlled at 24-28℃ and the relative humidity should be 90%-95%. Keep the air fresh and use diffused light. When spraying water, pay attention to using plasticizer-free metal pipes for water delivery. S3. After the Ganoderma lucidum matures, its fruiting body begins to release spores. A layer of food-grade paper is laid on the mulch to isolate plasticizers and prevent the spores from being contaminated by plasticizers during collection. S4. Spread the collected spore powder evenly on clean, smooth paper and place it in a well-ventilated, sunny place to dry. The entire process from inoculation to drying of the spore powder is carried out in an environment free of plasticizers.
