Description

Technical Field

[0001] The present invention relates to the technical field of edible mushroom cultivation, and particularly relates to a cultivation method for producing Stropharia rugosoannulata using a fermentation tunnel. Background Art

[0002] Stropharia rugosoannulata is commonly known as wrinkled globe mushroom and wrinkled ball cap mushroom. It is one of the mushroom species recommended by the Food and Agriculture Organization of the United Nations for cultivation in developing countries. Because of its bright appearance color, good marketability, smooth, tender and crispy mushroom quality, and rich nutrition, it is suitable for various cooking methods and is very popular among consumers. In recent years, Stropharia rugosoannulata has shown a strong development momentum across the country, with the consumer market constantly expanding, and the planting scale and planting benefits also continuously improving. With the increasingly prominent contradiction between development and the resource environment, the country has paid more and more attention to the utilization of resources, improving the propagation of Stropharia rugosoannulata, innovating the substrate formula of Stropharia rugosoannulata, achieving cost reduction and efficiency increase, and sustainable development is the future development direction of Stropharia rugosoannulata.

[0003] In the prior art, the fermentation tunnel for cultivating and producing Stropharia rugosoannulata only has a single function, which is heating fermentation and stirring. It cannot achieve automatic feeding and requires manual feeding. Therefore, it consumes a large amount of manpower and material resources and cannot achieve multi-functional fermentation at the same time. In order to solve the above existing problems according to the prior art, we propose a cultivation method for producing Stropharia rugosoannulata using a fermentation tunnel to achieve staged heating fermentation, stirring and feeding, so as to solve the defects in the prior art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to propose a cultivation method for producing Stropharia rugosoannulata using a fermentation tunnel, which has a simple structure and convenient operation and can effectively solve the technical problems existing in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: a cultivation method for producing Stropharia rugosoannulata using a fermentation tunnel, including a fermentation tunnel, an L-shaped feeding table and a roller. The L-shaped feeding table abuts against the rear end of the fermentation tunnel, and a baffle is detachably arranged at the front end of the L-shaped feeding table. The roller includes a heating element, a hollow sleeve and a discharge cavity. The roller is equidistantly fixed with three grooves, and a hollow sleeve is sleeved outside the roller. The grooves and the hollow sleeve form a discharge cavity. This cultivation method includes three stages:

[0006] The first stage is the temperature-raising and stirring stage. The main material of the cultivation material is spread flat on the L-shaped feeding table, the temperature of the material is raised to 35-45 °C and maintained for 3-5 days, and the cultivation material is heated and stirred by the roller.

[0007] The second stage is the temperature-raising, feeding and stirring stage. The main material of the cultivation material is raised to 55-70 °C and maintained for 10-15 days, and auxiliary materials are added to the main material of the cultivation material by the roller.

[0008] The third stage is the constant-temperature stirring stage. Keep the temperature of the cultivation material at 60 - 65 °C and the oxygen content at 45 - 65% for 3 - 5 days. When most of the cultivation material changes from light to dark, the fermentation of the cultivation material is completed.

[0009] Furthermore, in the first stage, the rotation speed of the roller is 130 - 180 r / min to mix the main materials of the cultivation material evenly; in the second stage, the rotation speed of the roller is 240 - 300 r / min to add auxiliary materials to the main materials of the cultivation material and make the main materials and auxiliary materials mix evenly; in the third stage, the rotation speed of the roller is 100 - 120 r / min to lower the temperature of the cultivation material.

[0010] Furthermore, the L-shaped material placement table is fixedly provided with a plurality of ventilation holes for dredging; the horizontal section of the L-shaped material placement table is higher at the front and lower at the rear, and the ground clearance at the front end of the L-shaped material placement table is less than the ground clearance at the rear end of the L-shaped material placement table; steam is used to heat the cultivation material through the ventilation holes from the bottom of the L-shaped material placement table; by virtue of the fact that the horizontal section of the L-shaped material placement table is higher at the front and lower at the rear, the moisture at the bottom of the cultivation material is discharged through the ventilation holes.

[0011] Furthermore, the discharge port is provided with a plurality of fan-shaped thin flaps that can open and close with each other, and the fan-shaped thin flaps have recoverable elasticity; when the roller rotates at a certain speed, the plurality of fan-shaped thin flaps open with each other.

[0012] Furthermore, the fan-shaped thin flaps are made of rubber, and the thickness gradually thins from the end connected to the discharge port to the free end.

[0013] Furthermore, the main materials of the cultivation material include the following weight components: 18 - 22 parts of wood chips, 28 - 32 parts of corncobs, 18 - 22 parts of mushroom residue, and 8 - 12 parts of rice husks; the auxiliary materials of the cultivation material include the following weight components: 0.5 - 1.5 parts of lime, 0.5 - 1.5 parts of gypsum, and 0.8 - 1.2 parts of white sugar.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] First, in the present invention, a cultivation method for producing Stropharia rugoso-annulata using a fermentation tunnel includes a fermentation tunnel, an L-shaped feeding table, and a roller. The L-shaped feeding table abuts against the rear end of the fermentation tunnel. A baffle is detachably provided at the front end of the L-shaped fermentation tunnel. The roller is movably arranged up and down and back and forth inside the upper end of the fermentation tunnel through a driving device. The roller includes a heating element, a hollow sleeve, and a discharge cavity. Three grooves are equidistantly and fixedly provided on the roller, and a hollow sleeve is sleeved outside the roller. One end of the hollow sleeve is closed, and the other end is openable and closable; the groove and the hollow sleeve form a discharge cavity. This cultivation method includes three stages: First, spread the main material of the cultivation material on the L-shaped feeding table, raise the material temperature to 35-45°C, maintain it for 3-5 days, and heat and stir the cultivation material through the roller; Second, raise the temperature of the main material of the cultivation material to 55-70°C, maintain it for 10-15 days, and add auxiliary materials to the main material of the cultivation material through the roller; Third, keep the temperature of the cultivation material at 60-65°C and the oxygen content at 45-65%, maintain it for 3-5 days. When most of the cultivation material changes from light to dark, the fermentation of the cultivation material is completed. Heating and stirring it is beneficial to make the material temperature consistent and prevent large differences in the fermentation degree due to local failure to reach the required temperature.

[0016] Second, in the present invention, the horizontal section of the L-shaped feeding table is higher at the front and lower at the rear, the vertical section of the L-shaped feeding table is much higher than the front end height of the L-shaped feeding table, and a baffle is detachably provided at the front end of the L-shaped feeding table. This setting is beneficial for facilitating the placement of the cultivation material and preventing the cultivation material from spilling out due to stirring.

[0017] Third, in the present invention, the L-shaped feeding table is fixedly provided with a plurality of ventilation holes for dredging; the horizontal section of the L-shaped feeding table is higher at the front and lower at the rear, which is beneficial for steam circulation and drainage of the cultivation material.

[0024] To make the objectives, technical solutions and advantages of the present invention clearer, the following provides a detailed description in conjunction with the accompanying drawings and specific implementation manners. Many specific details are set forth in the following description to facilitate a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementations disclosed below.

[0025] The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation manners.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] Such as Figure 1 、 Figure 2As shown in the figure, a device for producing Stropharia rugoso-annulata includes a fermentation tunnel 7 and an operation room. The fermentation tunnel 7 includes a heat preservation layer 71, an L-shaped material placement table 72, and rollers 73. The L-shaped material placement table 72 is abutted and arranged at the inner rear end of the fermentation tunnel 7. Preferably, the heat preservation layer 71 is built with bricks, and a delicate cement layer is laid on the inner surface; the L-shaped material placement table 72 includes, but is not limited to, iron plates, steel plates or alloy plates, and a plurality of ventilation holes for steam circulation and drainage are fixedly provided on the L-shaped material placement table 72. The left and right sides and the upper end of the L-shaped material placement table 72 are hermetically abutted against the inner surface of the heat preservation layer 71, and the L-shaped material placement table 72 and the heat preservation layer 71 are fixed by connecting pieces such as screws and fasteners. Preferably, the L-shaped material placement table 72 includes a vertical section and a horizontal section. Among them, the horizontal section is a slope surface with the rear end lower than the front end to prevent the cultivation material from spilling from the front end. At the same time, the slope surface design is more conducive to the drainage of the L-shaped material placement table 72. Preferably, the ground height at the rear end is 0.5 times the ground height at the front end, and the length of the vertical section is 3 / 4 of the length of the horizontal section. Its setting is conducive to forming a larger material placement space, and will not cause the inclination angle of the front end of the horizontal section in the process to be too small, making it difficult to achieve drainage.

[0028] In addition, a baffle 74 is detachably arranged at the front end of the L-shaped material placement table 72 to further prevent the cultivation material from falling and spilling out during stirring, so that the L-shaped material placement table 72 can stack more cultivation materials and improve the processing capacity of the device for the cultivation materials. Specifically, the baffle 74 is a wooden board, a plastic board or a metal board, and it is detachably and vertically erected at the front end of the L-shaped material placement table 72 through connecting pieces such as screws and buckles, and the lower end of the baffle 74 abuts against the inner bottom surface of the heat preservation layer 71.

[0029] As Figure 1 , Figure 2 As shown in the figure, the rollers 73 are movably and rotatably arranged above the L-shaped material placement table 72 along the L-shaped material placement table 72 inside the fermentation chamber 7 through a driving mechanism. The two ends of the moving track of the rollers 73 are respectively recorded as the rear high point and the front low point. Among them, the rear high point should be higher than the stack of cultivation materials on the L-shaped material placement table 72, so that the rollers 73 are separated from the stack of cultivation materials when not in use, further preventing damage such as rust and extending the service life.

[0030] Preferably, the distance ΔH between the rollers 73 and the upper surface of the L-shaped material placement table 72 preferably ranges from 5 cm to 8 cm. Without the rollers 73 contacting the L-shaped material placement table 72, the cultivation materials at the bottom can be stirred by the rollers 73 as much as possible.

[0031] The diameter D of the rollers 73 preferably ranges from 18 cm to 30 cm.

[0032] To ensure that all the cultivation materials can be processed by the roller 73, the thickness H of the cultivation materials preferably takes values in the range of ΔH + D ≤ H ≤ D + 2 * ΔH. Taking ΔH = 5 cm and D = 25 cm as an example, the thickness H of the cultivation materials preferably takes values in the range of 30 cm - 35 cm. In the actual production process, to improve the output of the device, the cultivation materials can be stacked with a thickness H = 2 * (D + 2 * ΔH). When the roller 73 moves from the high point at the rear end to the low point at the front end, the distance between the roller 73 and the upper surface of the L-shaped material placement table 72 is kept approximately at ΔH = 5 cm through the driving mechanism, that is, the distance between the geometric center of the roller 73 and the upper surface of the L-shaped material placement table 72 is kept approximately at (ΔH + D / 2) = 17.5 cm; when the roller 73 moves back to the high point at the rear end from the low point at the front end, the roller 73 is lifted through the driving mechanism so that the distance between the roller 73 and the upper surface of the L-shaped material placement table 72 is kept approximately at 3 * ΔH + D = 35 cm, that is, the distance between the geometric center of the roller 73 and the upper surface of the L-shaped material placement table 72 is kept approximately at 3 * (ΔH + D / 2) = 52.5 cm. By using the staggered levels of the reciprocating path of the roller 73, it is ensured that all the cultivation materials can be processed by the roller 73.

[0033] In a specific embodiment, the driving mechanism includes a one-dimensional electric screw slide table 734, an electric telescopic rod 735, and a servo motor 736. Both ends of the roller 73 are rotatably connected to the lower end of the piston rod of the electric telescopic rod 735 through bearing seats 730, and one end of the roller 73 is connected to the output shaft of the servo motor 736. The body of the servo motor 736 is fixedly connected to the piston rod of the electric telescopic rod on the same side through a connecting seat. The two electric telescopic rods are vertically arranged, and the upper ends of the two electric telescopic rods 735 are suspended from the inner top of the fermentation tunnel 7 through a one-dimensional electric screw slide table 734 and can move back and forth, and the two one-dimensional electric screw slide tables 734 are synchronously linked through a transmission shaft. During use, the roller 73 is driven to rotate by the servo motor 736, the roller 73 is driven to move up and down by the electric telescopic rod 735, and the roller 73 is driven to move back and forth by the one-dimensional electric screw slide table 734. Among them, the one-dimensional electric screw slide table 734, the electric telescopic rod 735, and the bearing seat are prior arts, and their specific structures will not be described in detail here.

[0034] Furthermore, Figure 1 In a specific embodiment, steam is used to heat the cultivation materials through the ventilation holes from the bottom of the L-shaped material placement table 72, and the moisture at the bottom of the cultivation materials is discharged through the ventilation holes by using the front-high and rear-low horizontal section of the L-shaped material placement table 72. More specifically, the components outside the fermentation tunnel 7 are the components inside the operation room. Figure 1For the convenience of display, no clear division is made. The operation room includes a steam generator 1, a high-pressure blower 2, a ventilation duct 3, an air filter 4, and a return air duct 6. The steam generated by the steam generator 1 enters the chamber enclosed by the inner surface of the heat-insulating layer 71, the lower surface of the L-shaped material placing table 72, and the roller 73 through the steam valve 11, and then is transferred to the upper surface (i.e., the material placing surface) of the L-shaped material placing table 72 through the ventilation holes, thereby heating the cultivation material inside the fermentation tunnel 7. The operation room includes two routes. One is the circulating air route. The steam generator 1 heats the fermentation tunnel 7 through the steam valve 11. When the steam generator 1 and the high-pressure blower 2 are turned on, the gas circulates through the ventilation duct 3, the chamber, and the return air duct 3 in sequence. The other is the fresh air route. When the steam generator 1, the high-pressure motor 2, and the air filter 4 are turned on, the gas is introduced as fresh air through the fresh air valve 41, the high-pressure motor 2, the ventilation duct 3, and the chamber in sequence.

[0035] As Figures 1-4 shown, three grooves are equidistantly arranged in the middle of the annular shape of the roller 73, and a hollow sleeve 737 for closing the three grooves is sleeved outside the roller 73, so that the roller 73 and the hollow sleeve 737 form three discharge cavities 732. A plurality of circular discharge ports 733 are uniformly arranged at the corresponding positions of the hollow sleeve 737 in the discharge cavity 732. Four mutually expandable and contractible fan-shaped thin flaps 7330 are fixedly provided at the discharge ports 733 by means of gluing, clamping, etc. The fan-shaped thin flaps 7330 have recoverable elasticity, and when the four fan-shaped thin flaps 7330 are closed to each other, the discharge ports 733 are sealed. When the roller 73 rotates at a certain speed, the four fan-shaped thin flaps 7330 open to each other, thereby opening the discharge ports 733.

[0036] As a specific embodiment, the roller 73 and the hollow sleeve 737 are made of corrosion-resistant stainless steel, which is beneficial to preventing them from rusting due to moisture and heat, thereby extending the service life. In order to strengthen the sleeved relationship between the hollow sleeve 737 and the roller 73, the two can be locked with screws. In addition, a plurality of limiting convex strips corresponding to the grooves of the roller 73 can be provided on the inner wall of the hollow sleeve 737. These limiting convex strips extend along the length direction of the hollow sleeve 737, and a clamping relationship is formed between the limiting convex strips and the edges of the grooves, thereby preventing the hollow sleeve 737 and the roller 73 from rotating relative to each other.

[0037] As another specific embodiment, the roller 73 and the hollow sleeve 737 are made of corrosion-resistant stainless steel, which is beneficial to preventing them from rusting due to moisture and heat, thereby extending the service life. In addition, the hollow sleeve 737 and the roller 73 are welded and fixed by welding, and the sealing performance of the discharge cavity 732 is ensured.

[0038] One of them is a discharge cavity 732, and a plurality of circular discharge ports 733 are fixedly arranged on the outer surface of the discharge cavity 732, and four fan-shaped thin flaps 7330 that can be opened and closed with each other are integrally formed. The four fan-shaped thin flaps 7330 seal the discharge port 733 when they are closed with each other, and open the discharge port 733 when they are opened with each other.

[0039] The roller 73 is provided with a heating element 731, which is used to enable the roller 73 to have a heating function. In a specific embodiment, the heating element 731 is an existing electric heating plate. The electric heating plate is sandwiched between the outer circumferential surface of the roller 73 and the inner wall of the hollow sleeve 737. More specifically, the roller 73 is provided with heating elements 731 in the circumferential surface area between two adjacent discharge cavities 732, and the heating surface of the heating element 731 is arranged outwardly and abutted against the inner wall of the hollow sleeve 737.

[0040] These heating elements 731 can be connected to the mains via a cable (not shown in the figure) for power supply and on / off control. In this case, a rotary joint needs to be installed at one end of the roller 73 to facilitate external cable connection. The use of a rotary joint to realize internal power supply of the rotating element belongs to the prior art and will not be described in detail here. A rechargeable lithium battery can also be installed inside the roller 73 to directly power the electric heating plate 731 and control its on / off.

[0041] Preferably, the number of the discharge cavities 732 is three, and the three discharge cavities 732 are equidistantly distributed outside the roller 73, which is conducive to reducing the loss during use and thus extending its service life. However, it is not limited to three, and can be four, five, etc., and these grooves can be equidistantly arranged outside the roller 73.

[0042] Preferably, the fan-shaped thin flaps 7330 include but are not limited to rubber products. In addition, the number of the fan-shaped thin flaps 7330 is not limited to four, and can be increased or decreased as needed. The thickness of the fan-shaped thin flaps gradually becomes thinner from one end connected to the discharge port 733 to the free end, which is conducive to the fan-shaped thin flaps opening outward after being stressed, and the auxiliary materials for placing the cultivation material in the discharge cavity 733 are 0.5-1.5 parts of lime, 0.5-1.5 parts of gypsum and 0.8-1.2 parts of white sugar, and the auxiliary materials are granular, while the main materials of the cultivation material include the following weight components: 18-22 parts of sawdust, 28-32 parts of corn cobs, 18-22 parts of mushroom residues and 8-12 parts of husks, which are mainly rod-shaped or block-shaped. Therefore, when the fan-shaped thin flaps open outward after being stressed, the auxiliary materials are added to the main materials of the cultivation material through the opened gaps, and due to the shape of the main materials of the cultivation material, the discharge port 733 will not be completely closed and blocked.

[0043] Preferably, in order to improve the stirring efficiency, a plurality of stirring blades (not shown in the figure) may be provided on the outside of the heating element 731. The specific structure of the stirring blades may refer to the blade structure of an existing stirring device, such as a spiral ribbon dispersion blade.

[0044] Furthermore, according to the centrifugal force calculation formula: F = mg = mrw 2 And the radius of the discharge port 733 is 2 cm, and then it is calculated that: when the rotation speed of the roller 73 is equal to or greater than 212 r / min, the cultivation material inside the discharge chamber 732 is stretched open by the centrifugal force, so that the discharge port 733 is opened, and the auxiliary material in the discharge chamber 732 is thrown out from the discharge port 733, so as to achieve the purpose of uniformly adding the auxiliary material to the main material during the stirring process; therefore, when the rotation speed of the roller 73 is less than 212 r / min, the cultivation material inside the discharge chamber 732 is insufficient to stretch open the fan-shaped thin petals under the action of the centrifugal force, and no auxiliary material is added.

[0045] In the actual production process, there are three stages in the fermentation of the culture medium, including:

[0046] The first stage is the heating and stirring stage, with a rotation speed of 130-180r / min, which is used to stir the main ingredients of the cultivation material to mix the main ingredients evenly and heat them at the same time, but no auxiliary materials are added; the preferred rotation speed is 170r / min to make the main ingredients more fully stirred and mixed.

[0047] The second stage is the heating, adding and stirring stage, with a speed of 240-300r / min. While stirring and heating the main material, the auxiliary material is evenly mixed into the main material. The preferred speed is 260r / min to ensure that the auxiliary material can be thrown out at an appropriate speed.

[0048] The third stage is the cooling and stirring stage, with a rotation speed of 100-120r / min, preferably 110r / min, stirring and heating the mixed cultivation material to accelerate the temperature drop, keep the cultivation material warm and keep the material temperature uniform everywhere, and no auxiliary materials are added.

[0049] like Figure 1 , Figure 2 As shown, the L-shaped material placing platform 72 is high at the front and back sides and low in the middle, wherein the rear end of the L-shaped material placing platform is much higher than the front end of the L-shaped material placing platform 72, and the upper surface of the L-shaped material placing platform 72 is paved with a Dutch net and a sunshade net in sequence, the Dutch net is placed between the L-shaped material placing platform 72 and the sunshade net, so that it supports the sunshade net, and the L-shaped material placing platform 72 and the sunshade net form a certain distance, and the sunshade net can prevent the cultivation material from blocking the vents, and the Dutch net and the sunshade net are used together to ensure the flowability of the vents (i.e., steam flow and water flow), ensure that the cultivation material is separated from the bottom water in time, avoid excessive water causing the bottom of the cultivation material to become moldy and rotten, that is, prevent the formation of green mold at the bottom of the cultivation material. And a drainage pipe is arranged directly below the lowest point of the L-shaped material placing platform 72, and the drainage pipe drains the fermentation tunnel 7 by opening the drainage valve 75, which is conducive to the outflow of water inside the cultivation material.

[0050] likeFigures 1-4 As shown in Figures 1-4 , a cultivation method for producing Stropharia rugoso-annulata using a fermentation tunnel specifically includes the following steps:

[0051] a1) Spread the main material of the cultivation material evenly on the L-shaped material placement table 72. By turning on the steam generator 1 and the heating element 731, the temperature of the material is raised to 35 - 45 °C and maintained for 3 - 5 days. At the same time, the roller 73 moves up and down, back and forth through the one-dimensional electric screw table 734 and the electric telescopic rod 735, and rotates through the servo motor 736, thereby stirring the cultivation material. Its rotation speed is 170 r / min to heat and stir the main material of the cultivation material, so that the temperature of the main material of the cultivation material is synchronously maintained at the preset temperature;

[0052] b1) The fermentation tunnel 7 raises the temperature of the material to 55 - 70 °C through the steam generator 1 and the heating element 731, maintains it for 10 - 15 days, and maintains the ratio of circulating air to fresh air so that the oxygen content of the cultivation material is 45 - 65%; at the same time, the roller 73 moves up and down, back and forth through the one-dimensional electric screw table 734 and the electric telescopic rod 735, and rotates through the servo motor 736, thereby stirring the cultivation material. Its rotation speed is 250 r / min for 1 h and 300 r / min for 1 h. When the rotation speed of the roller 73 reaches 250 r / min, the discharge cavity 732 adds auxiliary materials to the main material of the cultivation material. The alternation of the two is conducive to ensuring that the auxiliary materials in the discharge cavity 732 are completely added to the formulated auxiliary materials. After the auxiliary materials are completely added, the rotation speed of the roller 73 is maintained at 250 r / min to make the main material and auxiliary materials of the cultivation material fully mixed and uniform;

[0053] c1) The fermentation tunnel 7 adjusts the temperature of the steam generator 1 and the heating element 731 to 60 - 65 °C and adjusts the ratio of circulating air to fresh air so that the temperature of the cultivation material is maintained at 60 - 65 °C and the oxygen content of the cultivation material is 45 - 65%. The temperature is 60 - 65 °C and maintained for 3 - 5 days. At the same time, the rotation speed of the roller 73 is adjusted to 110 r / min to stir the cultivation material, so that the temperature of the cultivation material is maintained at 60 - 65 °C. When most of the cultivation material changes from light to dark, the cultivation material fermentation is completed;

[0054] d1) After the cultivation material fermentation is completed, the roller 73 moves to the starting position (i.e., above the inner rear end of the fermentation tunnel 7) through the one-dimensional electric screw table 734 and the electric telescopic rod 735. By removing the baffle 74, the cultivation material is removed for standby.

[0055] It will be understood that the present invention is described by way of some embodiments, and those skilled in the art will be aware that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. Additionally, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are within the scope protected by the present invention.

The L-shaped feeding table (72) abuts against the rear end of the fermentation tunnel. A baffle (74) is detachably arranged at the front end of the L-shaped feeding table (72). The rollers (73) are arranged at the upper end inside the fermentation tunnel (7) so as to be movable up and down and back and forth through a driving device. The rollers (73) include heating elements (731), hollow sleeves (737) and discharge cavities (732). Three grooves are fixedly arranged on the rollers (73) at equal intervals, and a hollow sleeve (737) is sleeved outside the rollers (73). The grooves and the hollow sleeves (737) form the discharge cavities (732). A plurality of circular discharge ports (733) are uniformly arranged at corresponding positions of the hollow sleeves (737) in the discharge cavities (732). A plurality of mutually expandable and contractible sector-shaped thin flaps (7330) are arranged at the discharge ports (733), and the sector-shaped thin flaps (7330) have recoverable elasticity. When the rollers (73) rotate at a certain speed, the plurality of sector-shaped thin flaps (7330) expand mutually. The method includes three stages: The first stage is the temperature-raising and stirring stage. The main material of the cultivation material is spread flat on the L-shaped feeding table (72), the temperature of the material is raised to 35-45 °C and maintained for 3-5 days, and the cultivation material is heated and stirred by the rollers (73). The second stage is the temperature-raising, feeding and stirring stage. The main material of the cultivation material is raised to 55-70 °C and maintained for 10-15 days, and auxiliary materials are added to the main material of the cultivation material by the rollers (73). The third stage is the constant-temperature stirring stage. The temperature of the cultivation material is maintained at 60-65 °C and the oxygen content is 45-65%. It is maintained for 3-5 days. When most of the cultivation material changes from light to dark, the cultivation material fermentation is completed.

2. The method for producing cultivation materials for Stropharia rugosoannulata using a fermentation tunnel according to claim 1, characterized in that: In the first stage, the rotation speed of the rollers (73) is 130-180 r / min to mix the main material of the cultivation material evenly. In the second stage, the rotation speed of the rollers (73) is 240-300 r / min to add auxiliary materials to the main material of the cultivation material and make the main material and the auxiliary materials mix evenly. In the third stage, the rotation speed of the rollers (73) is 100-120 r / min to lower the temperature of the cultivation material.

3. The method for producing cultivation materials for Stropharia rugosoannulata using a fermentation tunnel according to claim 1, characterized in that: A plurality of ventilation holes for dredging are fixedly arranged on the L-shaped feeding table (72). The horizontal section of the L-shaped feeding table (72) is higher at the front and lower at the rear, and the ground clearance of the front end of the L-shaped feeding table (72) is less than the ground clearance of the rear end of the L-shaped feeding table (72). Steam is used to heat the cultivation material through the ventilation holes from the bottom of the L-shaped feeding table (72). By virtue of the fact that the horizontal section of the L-shaped feeding table (72) is higher at the front and lower at the rear, the moisture at the bottom of the cultivation material is discharged through the ventilation holes.
