Description

Technical Field

[0001] The invention belongs to the technical field of ganoderma lucidum production, and in particular relates to a device and a method for preventing plasticizer from migrating into spore powder during the growth of ganoderma lucidum. Background Art

[0002] Plasticizer, also known as plasticizer, is a polymer material additive widely used in industrial production. Its main component is phthalate. Excessive intake can have serious effects on human health.

[0003] During the growth process of Ganoderma lucidum, plasticizers in the planting soil, irrigation water and air can all migrate into Ganoderma lucidum. When planting Ganoderma lucidum, the use of clean soil and water can be strictly controlled to prevent plasticizers in the soil and water from migrating into Ganoderma lucidum. However, the air environment in which Ganoderma lucidum grows is difficult to control artificially, and it is difficult to avoid the migration of plasticizers in the air into Ganoderma lucidum.

[0004] The current method to prevent plasticizers in the air from migrating into Ganoderma lucidum is to keep the greenhouse ventilated. However, this method can only reduce the plasticizers volatilized from plastic products in the greenhouse, and cannot reduce the plasticizers carried in the air due to pollution. Moreover, ventilation cannot clean the plasticizers in the air, and plasticizers still exist in the air and affect the air quality. Summary of the invention

[0005] The purpose of the present invention is to provide a device and method for preventing plasticizer from migrating into spore powder during the growth of Ganoderma lucidum in response to the problems raised in the above background technology.

[0006] To achieve the above object, the present invention adopts the following technical scheme: a device and method for preventing plasticizer from migrating into spore powder during the growth of Ganoderma lucidum, comprising:

[0007] A trolley, wherein a guide rail is provided under the trolley and the guide rail is laid along the length direction of the planting greenhouse;

[0008] A purification barrel, wherein a suction fan is provided on the top of the purification barrel, an air guide pipe is provided on the suction fan, a fixed sleeve is provided on the air guide pipe, an air supply pipe is provided between the fixed sleeve and the bottom of the purification barrel, a plurality of jet pipes distributed in a circular array are provided at the bottom of the air supply pipe, when the suction fan is turned on, the air in the planting greenhouse is sucked in and then sprayed out through the jet pipe, and when the air is sprayed out from the jet pipe, the jet pipe and the air supply pipe are driven to rotate around the central axis of the air supply pipe, and an exhaust pipe is provided on the top of the purification barrel.

[0009] Furthermore, the purification barrel is filled with Tween-80 solution, in which immobilized thermophilic esterase is mixed. After air enters the purification barrel, it is dissolved in water under the action of Tween-80, and the plasticizer in the air is degraded under the action of the immobilized thermophilic esterase.

[0010] Furthermore, a rotating shaft penetrating the trolley is provided at the bottom end of the gas pipe, a worm is provided on the rotating shaft, and a worm wheel cooperating with the worm is provided on the driving shaft of the trolley, so that the trolley is driven to move slowly when the gas pipe rotates.

[0011] Furthermore, a booster assembly is provided in the purification barrel, and the booster assembly includes a booster plate slidably connected to the side wall of the purification barrel, and a plurality of through holes distributed in a circular array are opened on the booster plate, and a plurality of mounting plates are provided on the side wall of the purification barrel, and a movable rod passing through the mounting plate is provided on the mounting plate, and buoyancy balls are provided at both ends of the movable rod, and the diameter of the buoyancy ball is larger than the diameter of the through hole.

[0012] Furthermore, the boost assembly also includes a nut fixed above the boost plate, and the air pipe is provided with a threaded sleeve that cooperates with the nut thread. The thread of the threaded sleeve adopts a reciprocating thread, and when the air pipe rotates, the boost plate is driven to move back and forth up and down.

[0013] Furthermore, the trolley is provided with a condensation assembly, which includes a support frame fixed on the trolley, a central axis is provided on the support frame, a condensation plate is provided at the bottom end of the central axis, and the condensation plate is in a truncated cone shape.

[0014] Furthermore, a wing plate is provided on the side wall of the condensation plate, and when air is discharged from the exhaust pipe, the wing plate drives the condensation plate to rotate.

[0015] Furthermore, a reflux component is provided on the support frame, and the reflux component includes a funnel fixed on the support frame. A reflux pipe is provided at the outlet of the funnel, and the reflux pipe is connected to the purification barrel.

[0016] The present invention also provides a method for preventing plasticizer from migrating into spore powder during the growth of Ganoderma lucidum, comprising the following steps:

[0017] S1. Prepare the culture medium. Wrap a layer of fungus bag on the surface of the culture medium. Put a layer of tin foil between the fungus bag and the culture medium to prevent the migration of plasticizer. Put the culture medium into the sterilizer and heat it at 1.5kg / cm 2 Sterilize under sterile conditions for 1.5 to 2 hours. After the culture medium is sterilized, inoculate under sterile conditions. Put the inoculated bags into the greenhouse, cover the bags with a layer of mulch, control the temperature at 22 to 30°C, preferably 24 to 28°C, keep away from light, pay attention to ventilation and cooling, check once a week or so, discard the contaminated bags, the mycelium will grow in about 10 days, turn on the suction fan in the device 2-3 days before putting the bags into the greenhouse to purify the air in the greenhouse;

[0018] S2. When the mycelium grows to about 30 days and buds are formed on the surface, the bag is untied to make the Ganoderma grow outwards. The buds extend outwards to form a stem. A cap grows on the stem in about 15 days. After 30 to 50 days of maturity, spores are released from the cap and can be harvested. At this stage, ventilation and water spraying should be taken. The temperature should be controlled at 24 to 28 ° C and the relative humidity of the air should be 90% to 95%. The air should be kept fresh and scattered light should be used. When spraying water, attention should be paid to the use of metal pipes without plasticizers for water delivery pipes.

[0019] S3. After the Ganoderma lucidum matures, its fruiting body begins to spray spore powder. A layer of food-grade paper is laid on the ground film to isolate the plasticizer to prevent the spore powder from being contaminated by the plasticizer when it is collected;

[0020] S4. Spread the collected spore powder evenly on clean and smooth paper and place it in a well-ventilated and sunny place for drying. The entire process from inoculation of the strain to drying the spore powder is in a plasticizer-free environment.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] 1. In the present invention, when cultivating strains, tin foil is placed between the bacteria bag and the culture medium to prevent the migration of plasticizers. The air in the greenhouse is purified 2-3 days before the bacteria bag is moved into the greenhouse to remove the plasticizers in the air. The water pipe used for the irrigation of ganoderma lucidum is a metal pipe to prevent the plasticizers in the air and water source from migrating into the ganoderma lucidum during the growth process. Paper is placed when the spore powder is collected and aired. The whole process from the inoculation of the bacteria to the airing of the spore powder is in a plasticizer-free environment, which can effectively prevent the plasticizer from migrating into the spore powder.

[0023] 2. The present invention sets an air jet pipe, and the suction fan sucks the air in the greenhouse into the purification barrel for purification. When the air is ejected from the air jet pipe, it drives the air pipe to rotate, thereby driving the trolley to move. While purifying the air, the trolley continuously moves its position, thereby improving the purification effect. The reaction force received by the air jet pipe when ejecting air is cleverly utilized to drive the air pipe to rotate and drive the trolley to move. There is no need to add an additional motor drive for the trolley, thereby reducing the equipment cost.

[0024] 3. The present invention provides an air jet pipe, which drives the air pipe to rotate and stirs the Tween-80 solution in the purification barrel, so that the plasticizer is more evenly dispersed in the Tween-80 solution and better contacts the immobilized thermophilic esterase, thereby improving the efficiency of plasticizer degradation and completely removing the plasticizer in the air by promoting the degradation of the plasticizer.

[0025] 4. The present invention sets a boosting component. When the air pipe rotates, it drives the boosting plate to move up and down reciprocatingly. When the boosting plate moves downward, after the through hole contacts the buoyancy ball, the boosting plate continues to push the buoyancy ball downward, and the pressure below the boosting plate increases, so that the air is forced to dissolve in the Tween-80 solution. When the boosting plate moves upward, before the through hole separates from the buoyancy ball, the pressure below the boosting plate decreases, the air is released again and a large number of microbubbles are generated. The volume of bubbles formed after the air enters the solution is reduced by the pressurized dissolved air release method, so that the air and the solution are in contact more fully, the plasticizer in the air can be better dissolved in the solution, and the purification effect of the plasticizer is improved.

[0026] 5. The present invention sets a condensation component and a reflux component. When the boost plate moves up, the through hole is separated from the buoyancy ball. The purified air flows from the through hole to the top of the boost 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 toward the condensation plate. The condensation plate liquefies the water vapor carried in the air and then introduces it into the purification box through the reflux pipe for continued use, thereby avoiding the reduction of the solution in the purification box and avoiding changing the air humidity in the greenhouse when purifying the air.

[0027] 6. The present invention sets a wing plate. When air blows toward the condensation plate, the condensation plate is driven to rotate under the action of the wing plate, so that the air is always blown at different positions of the condensation plate, avoiding the air blowing to the same position of the condensation plate causing the temperature of the condensation plate to increase, thereby ensuring the effect of the condensation plate in liquefying water vapor, and when the condensation plate rotates, the water droplets thereon quickly fall into the funnel under the action of centrifugal force, avoiding the residual water droplets on the condensation plate affecting the condensation effect.

[0047] During specific operation, the suction fan 21 sucks the air in the greenhouse into the purification barrel 2 for purification. The plasticizer in the air is dissolved in water under the action of Tween-80. When the air is ejected from the jet pipe 24, it drives the air pipe 23 to rotate and stir the Tween-80 solution 26 in the purification barrel 2, so that the plasticizer is more evenly dispersed in the Tween-80 solution 26 and better contacts with the immobilized thermophilic esterase 27. The immobilized thermophilic esterase 27 promotes the degradation of the plasticizer, thereby removing the plasticizer in the air.

[0048] A rotating shaft 31 penetrating the trolley 1 is provided at the bottom of the gas delivery pipe 23, and a worm 32 is provided on the rotating shaft 31. A worm wheel 33 cooperating with the worm 32 is provided on the driving shaft of the trolley 1. By utilizing the characteristics of the reduction transmission of the worm 32 and the worm wheel 33, when the gas delivery pipe 23 rotates, the trolley 1 is driven to move slowly.

[0049] During operation, the air delivery pipe 23 rotates to drive the rotating shaft 31 and the worm 32 to rotate, thereby driving the worm wheel 33 to rotate slowly and causing the trolley 1 to move slowly. While purifying the air, the trolley 1 continuously moves its position to improve the purification effect.

[0050] A booster assembly is provided in the purification barrel 2, and the booster assembly includes a booster plate 4 slidably connected to the side wall of the purification barrel 2, and a plurality of through holes 41 distributed in a circumferential array are opened on the booster plate 4, and a plurality of mounting plates 42 are provided on the side wall of the purification barrel 2. In this embodiment, the number of through holes 41 and mounting plates 42 is 8, and a movable rod 43 penetrating the mounting plate 42 is provided on the mounting plate 42, and buoyancy balls 44 are provided at both ends of the movable rod 43, and the diameter of the buoyancy ball 44 is larger than the diameter of the through hole 41. In a natural state, the buoyancy ball 44 at the bottom abuts against the mounting plate 42 under the action of buoyancy, and the booster assembly also includes a nut 45 fixed on the top of the booster plate 4, and a threaded sleeve 46 that matches the thread of the nut 45 is provided on the air supply pipe 23, and the thread of the threaded sleeve 46 adopts a reciprocating thread, and when the air supply pipe 23 rotates, the booster plate 4 is driven to reciprocate up and down;

[0051] During specific operation, when the air supply pipe 23 rotates, the threaded sleeve 46 is driven to rotate, and the boosting plate 4 is driven to reciprocate up and down under the action of the threads of the nut 45 and the threaded sleeve 46. When the boosting plate 4 moves downward, the through hole 41 contacts the buoyancy ball 44, and the boosting plate 4 continues to push the buoyancy ball 44 downward. The pressure below the boosting plate 4 increases, causing the air to be forced to dissolve in the Tween-80 solution 26. When the boosting plate 4 moves upward, before the through hole 41 separates from the buoyancy ball 44, the pressure below the boosting plate 4 decreases, and the air is released again and a large number of microbubbles are generated. The volume of bubbles formed after the air enters the solution is reduced by the pressurized dissolved gas release method, so that the air and the solution are in contact more fully, and the plasticizer in the air can be better dissolved in the solution, thereby improving the purification effect of the plasticizer.

[0052] A condensation assembly is provided on the trolley 1, and the condensation assembly includes a support frame 51 fixed on the trolley 1, a central axis 52 is provided on the support frame 51, a condensation plate 53 is provided at the bottom end of the central axis 52, and a condensation plate 53 adopts semiconductor refrigeration for cooling. The condensation plate 53 is truncated cone-shaped, and a wing plate 54 is provided on the side wall of the condensation plate 53.

[0053] A reflux assembly is provided on the support frame 51 , and the reflux assembly includes a funnel 61 fixed on the support frame 51 . A reflux pipe 62 is provided at the outlet of the funnel 61 , and the reflux pipe 62 is communicated with the purification barrel 2 .

[0054] During specific operation, when the boost plate 4 moves upward, the through hole 41 is separated from the buoyancy ball 44, and the purified air flows from the through hole 41 to the top of the boost 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 to the condensation plate 53, and the condensation plate 53 liquefies the water vapor carried in the air. When the air blows to the condensation plate 53, the wing plate 54 drives the condensation plate 53 to rotate, so that the air is always blown at different positions of the condensation plate 53, avoiding the air blowing to the same position of the condensation plate 53 causing the temperature of the condensation plate 53 to increase, ensuring the effect of the condensation plate 53 liquefying water vapor, the condensation plate 53 rotates so that the water droplets on it quickly fall into the funnel 61 under the action of centrifugal force, avoiding the residual water droplets on the condensation plate 53 affecting the condensation effect, and after the water droplets fall into the funnel 61, they are introduced into the purification box 2 through the reflux pipe 62 for continued use, avoiding the reduction of the solution in the purification box 2 and avoiding the change of the air humidity in the greenhouse when purifying the air.

[0055] In this embodiment, all the components mentioned in the above device are made of materials without plasticizer.

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

[0057] S1. Prepare the culture medium. Wrap a layer of fungus bag on the surface of the culture medium. Put a layer of tin foil between the fungus bag and the culture medium to prevent the migration of plasticizer. Put the culture medium into the sterilizer and heat it at 1.5kg / cm 2 Sterilize under sterile conditions for 1.5 to 2 hours, inoculate the culture medium under sterile conditions after sterilization, put the inoculated fungus bag into the greenhouse, cover the fungus bag with a layer of mulch, control the temperature at 22 to 30°C, preferably 24 to 28°C, store away from light, pay attention to ventilation and cooling, check once a week or so, discard the contaminated fungus bag, the mycelium can be fully grown in about 10 days, turn on the suction fan 21 in the device 2-3 days before putting the fungus bag into the greenhouse to purify the air in the greenhouse;

[0058] S2. When the mycelium grows to about 30 days and buds are formed on the surface, the bag is untied to make the Ganoderma grow outwards. The buds extend outwards to form a stem. A cap grows on the stem in about 15 days. After 30 to 50 days of maturity, spores are released from the cap and can be harvested. At this stage, ventilation and water spraying should be taken. The temperature should be controlled at 24 to 28 ° C and the relative humidity of the air should be 90% to 95%. The air should be kept fresh and scattered light should be used. When spraying water, attention should be paid to the use of metal pipes without plasticizers for water delivery pipes.

[0059] S3. After the Ganoderma lucidum matures, its fruiting body begins to spray spore powder. A layer of food-grade paper is laid on the ground film to isolate the plasticizer to prevent the spore powder from being contaminated by the plasticizer when it is collected;

[0060] S4. Spread the collected spore powder evenly on clean and smooth paper and place it in a well-ventilated and sunny place for drying. The entire process from inoculation of the strain to drying the spore powder is in a plasticizer-free environment.

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

[0062] The suction fan 21 is turned on 2-3 days before the planting of Ganoderma lucidum. The suction fan 21 sucks the air in the greenhouse into the purification barrel 2 for purification. The plasticizer in the air is dissolved in the water under the action of Tween-80. When the air is ejected from the jet pipe 24, the air pipe 23 is driven to rotate to stir the Tween-80 solution 26 in the purification barrel 2, so that the plasticizer is more evenly dispersed in the Tween-80 solution 26 and better contacted with the immobilized thermophilic esterase 27. The immobilized thermophilic esterase 27 promotes the degradation of the plasticizer, thereby removing the plasticizer in the air.

[0063] The rotation of the air pipe 23 drives the rotating shaft 31 and the worm 32 to rotate, thereby driving the worm wheel 33 to rotate slowly and causing the trolley 1 to move slowly. While purifying the air, the trolley 1 continuously moves its position, thereby improving the purification effect. The reaction force of the air jet pipe when jetting is cleverly used to drive the air pipe to rotate and drive the trolley to move. There is no need to add an additional motor drive to the trolley, thereby reducing the equipment cost.

[0064] When the air delivery pipe 23 rotates, the threaded sleeve 46 rotates, and the boosting plate 4 is driven to move up and down reciprocatingly under the action of the threads of the nut 45 and the threaded sleeve 46. When the boosting plate 4 moves down, the through hole 41 contacts the buoyancy ball 44, and the boosting plate 4 continues to push the buoyancy ball 44 to move down. The pressure below the boosting plate 4 increases, so that the air is forced to dissolve in the Tween-80 solution 26. When the boosting plate 4 moves up, before the through hole 41 separates from the buoyancy ball 44, the pressure below the boosting plate 4 decreases, and the air is released again and a large number of microbubbles are generated. The volume of bubbles formed after the air enters the solution is reduced by the pressurized dissolved gas release method, so that the air and the solution are in contact more fully, and the plasticizer in the air can be better dissolved in the solution, thereby improving the purification effect of the plasticizer;

[0065] When the boost plate 4 moves upward, after the through hole 41 is separated from the buoyancy ball 44, the purified air flows from the through hole 41 to the top of the boost 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 toward the condensation plate 53, and the condensation plate 53 liquefies the water vapor carried in the air. When the air blows toward the condensation plate 53, the wing plate 54 drives the condensation plate 53 to rotate, so that the air is always blown at different positions of the condensation plate 53, avoiding the air blowing to the same position of the condensation plate 53 causing the temperature of the condensation plate 53 to increase, ensuring the effect of the condensation plate 53 liquefying water vapor, the condensation plate 53 rotates so that the water droplets on it quickly fall into the funnel 61 under the action of centrifugal force, avoiding the residual water droplets on the condensation plate 53 affecting the condensation effect, and after the water droplets fall into the funnel 61, they are introduced into the purification box 2 through the reflux pipe 62 for continued use, avoiding the reduction of the solution in the purification box 2 and avoiding the change of the air humidity in the greenhouse when purifying the air.

[0066] The above are only 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 in the protection scope of the present invention.

Put the culture medium into the sterilizer and heat it at 1.5kg / cm 2 Sterilize under sterile conditions for 1.5 to 2 hours, inoculate the culture medium under sterile conditions after sterilization, put the inoculated fungus bag into the greenhouse, cover the fungus bag with a layer of mulch, control the temperature at 22 to 30° C., preferably 24 to 28° C., store away from light, pay attention to ventilation and cooling, check once a week or so, discard the contaminated fungus bag, the mycelium can grow in about 10 days, turn on the suction fan (21) in the device 2 to 3 days before putting the fungus bag into the greenhouse to purify the air in the greenhouse; S2. When the mycelium grows to about 30 days and buds are formed on the surface, the bag is untied to make the Ganoderma grow outwards. The buds extend outwards to form a stem. A cap grows on the stem in about 15 days. After 30 to 50 days of maturity, spores are released from the cap and can be harvested. At this stage, ventilation and water spraying should be taken. The temperature should be controlled at 24 to 28 ° C and the relative humidity of the air should be 90% to 95%. The air should be kept fresh and scattered light should be used. When spraying water, attention should be paid to the use of metal pipes without plasticizers for water delivery pipes. S3. After the Ganoderma lucidum matures, its fruiting body begins to spray spore powder. A layer of food-grade paper is laid on the ground film to isolate the plasticizer to prevent the spore powder from being contaminated by the plasticizer when it is collected; S4. Spread the collected spore powder evenly on clean and smooth paper and place it in a well-ventilated and sunny place for drying. The entire process from inoculation of the strain to drying the spore powder is in a plasticizer-free environment.
