Description

Technical Field

[0001] This invention relates to the field of fungal extract preparation technology, specifically to an apparatus and method for preparing Pleurotus ostreatus extract. Background Technology

[0002] Golden-topped oyster mushroom, also known as elm yellow mushroom or golden-topped mushroom, belongs to the genus Pleurotus in the family Pleurotaceae of the order Agaricales. It is delicious and nutritious, rich in protein, various vitamins and minerals, as well as amino acids, ergothioneine, and other active ingredients. It possesses tonic, strengthening, and antioxidant effects, and has broad application prospects and high development value in the food and pharmaceutical fields. The preparation of Golden-topped oyster mushroom extract is a key step in achieving its efficient resource utilization. The fermentation process, as the core step in extract preparation, directly affects the release efficiency, extraction purity, and product quality of the active ingredients in Golden-topped oyster mushroom. Therefore, the stability and rationality of the fermentation process are crucial to the entire preparation process. Currently, in the preparation of Golden-topped oyster mushroom extract, the fermentation process typically uses stirred fermentation equipment. Its core principle is to achieve thorough mixing of the Golden-topped oyster mushroom cells with the fermentation substrate and nutrient solution through the high-speed rotation of the stirring blades within the equipment, ensuring a uniform fermentation environment and promoting cell metabolism and the generation and release of active ingredients. Existing stirred fermentation equipment mostly employs a rigid blade design for its stirring structure. The blade directly contacts the Pleurotus ostreatus var. sarcodactylis and generates shearing and impact forces to achieve mixing. However, this type of equipment has significant technical defects in practical applications, severely restricting the preparation efficiency and product quality of Pleurotus ostreatus var. sarcodactylis extract, becoming a technical problem that urgently needs to be solved in the industry. On the one hand, the Pleurotus ostreatus cells are fragile. During high-speed rotation and stirring, the rigid stirring head of the existing equipment directly acts on the Pleurotus ostreatus cells with shearing and impact forces, which can easily cause cell wall damage and structural damage. This leads to premature leakage and oxidation of nutrients and active substances inside the cells, which not only reduces the extraction efficiency and active ingredient content of subsequent extracts, but also causes impurities generated by cell damage to enter the fermentation system, affecting the purity of the fermentation broth and increasing the difficulty and cost of subsequent separation and purification processes. Ultimately, this results in a decline in the quality of the prepared Pleurotus ostreatus extract, which cannot meet the application requirements of the food and pharmaceutical fields.

[0003] On the other hand, when the rigid blade directly acts on the Pleurotus ostreatus, the high-speed shearing and impact will break the Pleurotus ostreatus into a large number of fine particles. These fine particles are tiny and loose in texture, and they are very easy to clog the filter screen of the filtration equipment in the subsequent fermentation broth filtration and separation process. After the filter screen is clogged, the filtration efficiency will drop sharply, and frequent shutdowns will be required to disassemble the filter screen for cleaning or replacement. This not only interrupts the entire preparation process, but also increases the labor intensity of the operators and the equipment maintenance cost.

[0004] In view of this, we propose an apparatus and method for preparing Pleurotus ostreatus extract to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides the following technical solution: a device for preparing Pleurotus ostreatus extract, comprising: The silo has a base at the bottom for support. The silo contains goldenrod mushrooms for preparing goldenrod extract. The silo also has a filter plate that divides it into upper and lower areas.

[0007] As a preferred embodiment of the present invention, the power device includes two U-shaped plates fixedly installed at the bottom of the jigging plate. The two U-shaped plates are symmetrically distributed about the central axis of the jigging plate, and the bottom of each of the two U-shaped plates is hinged to a connecting rod through a spherical bearing. The power unit also includes two bearing seats fixedly mounted on the base, a transmission shaft rotatably mounted between the two bearing seats, two eccentric wheels fixedly mounted on the outer wall of the transmission shaft along its axial direction, and two connecting rods rotatably mounted around the two eccentric wheels respectively.

[0008] As a preferred embodiment of the present invention, the power device further includes a power motor fixedly mounted on a base, a pulley fixedly mounted on the output shaft of the power motor, and a driven pulley adapted to the specifications of the pulley fixedly mounted on the outer wall of the transmission shaft. The diameter ratio of the driven pulley to the diameter of the pulley is 3:1, and a plurality of power belts are sleeved between the driven pulley and the pulley.

[0009] As a preferred embodiment of the present invention, linear bearings are fixedly installed at the four corners of the jigging plate, and guide shafts are vertically fixedly installed at the four corners of the bottom of the hopper, with the linear bearings slidably installed around the guide shafts.

[0010] As a preferred embodiment of the present invention, the jigging device further includes a geared motor fixedly installed at the center of the bottom of the jigging plate. The output shaft of the geared motor movably passes through the jigging plate and extends into the interior of the first-stage jigging diaphragm. A sealed bearing is provided between the output shaft of the geared motor and the through hole of the jigging plate, and a first-stage impeller is fixedly installed at the upper end of the output shaft of the geared motor.

[0011] As a preferred embodiment of the present invention, the jigging device further includes a cross fixedly installed on the inner wall of the bottom of the hopper. The cross is located at the top of the jigging inlet. A bushing is fixedly installed at the center of the bottom of the cross. The middle part of the secondary jigging diaphragm covers the outer periphery of the bushing and is locked by a hose clamp. A vertical shaft is rotatably installed inside the bushing. A sealed bearing is provided between the vertical shaft and the bushing. The vertical shaft passes through the cross. A secondary impeller is fixedly installed at the top of the vertical shaft. A turbine is fixedly installed at the bottom of the vertical shaft. A gap is provided between the bottom of the turbine and the top of the primary impeller.

[0012] As a preferred embodiment of the present invention, a sheet metal induction plate is fixedly installed on one side of the jigging plate, and two slotted photoelectric switches distributed vertically are fixedly installed on the side of the base near the sheet metal induction plate, with the positions of the slotted photoelectric switches corresponding to the positions of the sheet metal induction plate, and the distance between the two slotted photoelectric switches matching the stroke of the jigging plate as it jumps up and down.

[0013] As a preferred embodiment of the present invention, a valve is fixedly installed at the output end below the outer side of the hopper, and a material pipe is fixedly installed at the output end of the valve.

[0014] A method for preparing Pleurotus ostreatus extract using an apparatus, comprising the following steps: S1. Place the mushrooms used to prepare Pleurotus ostreatus extract into the fermentation zone inside the silo. S2. Add specific amino acids to the hopper to promote the fermentation of Pleurotus ostreatus. The fruiting body of Pleurotus ostreatus is intercepted by the base, while the liquid extract of Pleurotus ostreatus produced by fermentation enters the collection area through the filter holes opened on the base. S3. The power unit drives the jigging device to operate. The secondary jigging diaphragm of the jigging device swings up and down, causing the liquid extract of Pleurotus ostreatus collected by the silo collector to jig up and down.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes the up-and-down movement of the jigging plate to create periodic pressure changes in the jigging liquid within the sealed cavity structure between the primary and secondary jigging membranes. These periodic pressure changes cause the secondary jigging membrane to periodically compress the *Mushroom simonii* extract liquid collected in the collection area inside the hopper. This causes the *Mushroom simonii* extract liquid to flow periodically up and down through the filter plate. As the *Mushroom simonii* extract liquid flows upward through the filter plate, it also prevents impurities from accumulating on the filter plate surface and causing blockages, ensuring the continuous and stable operation of the filtration process. This improves the overall efficiency and extraction quality of the preparation equipment. Simultaneously, it allows for better mixing and fermentation of *Mushroom simonii* and amino acids in the fermentation zone. As the *Mushroom simonii* extract liquid flows downward through the filter plate, its flow characteristics carry the precipitated *Mushroom simonii* extract downwards, further collecting it at the bottom of the equipment for subsequent collection.

[0016] 2. This invention uses a geared motor to drive a primary impeller to rotate, stirring the jigging liquid located between the primary and secondary jigging membranes. This disperses the jigging liquid as it jiggles upwards, thereby compressing the bottom of the secondary jigging membrane as a whole and improving the jigging effect of the secondary jigging membrane on the liquid extracted from *Pleurotus ostreatus* in the collection area inside the silo.

[0017] 3. When the first-stage impeller of this invention rotates under the drive of the geared motor, it not only stirs the jigging liquid and disperses it upwards, but also, due to the gap between the bottom of the turbine and the top of the first-stage impeller, the airflow or liquid flow generated by the rotation of the first-stage impeller drives the turbine to rotate, which in turn drives the second-stage impeller to rotate through the vertical shaft. The rotation of the second-stage impeller further enhances the dispersion effect of the Pleurotus ostreatus extract liquid, making the jigging process more thorough and uniform, thereby further improving the jigging separation effect of the Pleurotus ostreatus extract liquid.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-10 The technical solution provided by the present invention specifically includes the following embodiments: A device for preparing Pleurotus ostreatus extract includes a hopper 100, a base 200, a filter plate 300, and a jigging device 400. The base 200 is provided at the bottom of the hopper 100 to support it. Pleurotus ostreatus for preparing the extract is placed inside the hopper 100. The filter plate 300 divides the hopper 100 into upper and lower sections. The upper section of the filter plate 300 is the fermentation zone for the Pleurotus ostreatus extract, and the lower section is the fermentation zone for the Pleurotus ostreatus extract. In the collection area of ​​the mushroom extract, the filter plate 300 has multiple vertically formed filter holes to allow the extract of *Pleurotus ostreatus* to pass through. A jigging device 400 is fixedly installed at the bottom of the silo 100 and extends into the silo 100 to the bottom of the filter plate 300 to promote the fermentation and collection of the *Pleurotus ostreatus* extract. A jigging port 101 is formed through the bottom of the silo 100 to allow the jigging device 400 to enter. A power unit 500 is fixedly installed at the bottom of the jigging device 400 to provide power to it. *Pleurotus ostreatus* mushrooms used to prepare the extract are placed into the fermentation area inside the silo 100. Specific amino acids are then added to the silo 100 to promote fermentation. The fruiting bodies of the *Pleurotus ostreatus* mushrooms are intercepted by the base 200, while the liquid extract produced during fermentation enters the collection area through the filter holes on the base 200. The power unit 500 drives the jigging device 400, causing the liquid extract collected in the silo 100 to jiggle up and down, improving the fermentation effect.

[0022] For further details, please refer to [link / reference]. Figure 4 , Figure 5 , Figure 9 As shown: The jigging device 400 includes a secondary jigging diaphragm 401 fixedly installed on the inner wall of the bottom of the silo 100, and a primary jigging diaphragm 402 fixedly installed at the bottom of the silo 100. Both the secondary jigging diaphragm 401 and the primary jigging diaphragm 402 are made of flexible rubber. Both the secondary jigging diaphragm 401 and the primary jigging diaphragm 402 are located outside the jigging port 101, and a closed cavity structure is formed between the secondary jigging diaphragm 401 and the primary jigging diaphragm 402 through the jigging port 101. The closed cavity structure is filled with an appropriate amount of jigging liquid. A jigging plate 403 is fixedly installed at the bottom of the primary jigging diaphragm 402. The power unit 500 includes two U-shaped plates 501 fixedly installed at the bottom of the jigging plate 403. The two U-shaped plates 501 are symmetrically distributed about the central axis of the jigging plate 403, and each U-shaped plate 501 is hinged to a connecting rod 502 at its bottom via a spherical bearing. The power unit 500 also includes two bearing seats 503 fixedly mounted via a base 200. A drive shaft 504 is rotatably mounted between the two bearing seats 503. Two eccentric wheels 505 are fixedly mounted along the axial direction on the outer wall of the drive shaft 504. Rods 502 are rotatably mounted on the periphery of two eccentric wheels 505. The power unit 500 also includes a power motor 507 fixedly mounted on the base 200. A pulley 508 is fixedly mounted on the output shaft of the power motor 507. A driven pulley 506 with the same specifications as the pulley 508 is also fixedly mounted on the outer wall of the transmission shaft 504. The diameter ratio of the driven pulley 506 to the diameter of the pulley 508 is 3:1, and several power belts 509 are sleeved between the driven pulley 506 and the pulley 508. When the equipment is running, the power motor 507 starts, driving the driven pulley 506 to rotate via the pulley 508 and the power belt 509. Since the driven pulley 506 is fixedly connected to the drive shaft 504, the drive shaft 504 rotates accordingly, and the two eccentric wheels 505 on the drive shaft 504 also rotate. This, in turn, drives the jigging plate 403 to move up and down reciprocally via the connecting rod 502 and the U-shaped plate 501. The up and down movement of the jigging plate 403 causes periodic pressure changes in the jigging liquid within the sealed cavity structure between the primary jigging diaphragm 402 and the secondary jigging diaphragm 401. These periodic pressure changes cause the secondary jigging diaphragm 401 to collect the contents inside the hopper 100. The liquid extract from the golden cap mushroom collected in the collection area undergoes periodic compression, causing it to flow up and down periodically through the filter plate 300. As the liquid flows upward through the filter plate 300, impurities are prevented from accumulating and clogging the plate, ensuring a continuous and stable filtration process. This improves the overall efficiency and extraction quality of the equipment and allows for better mixing and fermentation of the golden cap mushrooms and amino acids in the fermentation zone. Conversely, as the liquid flows downward through the filter plate 300, its flow characteristics carry the precipitated extract downwards, further collecting it at the bottom of the equipment for easier subsequent collection.

[0023] For further details, please refer to [link / reference]. Figure 5 , Figure 8 As shown: Linear bearings 404 are fixedly installed at each of the four corners of the jigging plate 403, and guide shafts 405 are vertically fixedly installed at each of the four corners of the bottom of the hopper 100. The linear bearings 404 are slidably installed around the guide shafts 405. Through the cooperation between the linear bearings 404 and the guide shafts 405, the jigging plate 403 can maintain a stable motion trajectory during its up-and-down reciprocating motion, avoiding deviation or shaking. This ensures the uniformity and periodicity of the jigging liquid pressure change, enhancing the structural stability and reliability of the entire preparation equipment.

[0024] For further details, please refer to [link / reference]. Figure 9 As shown: The jigging device 400 also includes a geared motor 406 fixedly installed at the center of the bottom of the jigging plate 403. The output shaft of the geared motor 406 movably passes through the jigging plate 403 and extends into the interior of the primary jigging diaphragm 402. A sealed bearing is provided between the output shaft of the geared motor 406 and the through hole of the jigging plate 403, and a primary impeller 407 is fixedly installed at the upper end of the output shaft of the geared motor 406. As the jigging plate 403 moves upward, the geared motor 406 drives the primary impeller 407 to rotate, stirring the jigging liquid located between the primary jigging diaphragm 402 and the secondary jigging diaphragm 401. This disperses the jigging liquid during the upward jigging process, thereby compressing the bottom of the secondary jigging diaphragm 401 as a whole, improving the jigging effect of the secondary jigging diaphragm 401 on the liquid extracted from *Pleurotus ostreatus* in the collection area inside the silo 100.

[0025] For further details, please refer to [link / reference]. Figure 7 As shown: The jigging device 400 also includes a cross 408 fixedly installed on the inner wall of the bottom of the hopper 100. The cross 408 is located at the top of the jigging inlet 101. A bushing 409 is fixedly installed at the center of the bottom of the cross 408. The middle part of the secondary jigging diaphragm 401 covers the outer periphery of the bushing 409 and is locked by a hose clamp. A vertical shaft 4010 is rotatably installed inside the bushing 409. A sealed bearing is provided between the vertical shaft 4010 and the bushing 409. The vertical shaft 4010 passes through the cross 408. A secondary impeller 4011 is fixedly installed at the top of the vertical shaft 4010. A turbine 4012 is fixedly installed at the bottom of the vertical shaft 4010. A gap is provided between the bottom of the turbine 4012 and the top of the primary impeller 407. When the first-stage impeller 407 rotates under the drive of the geared motor 406, it not only stirs the jigging liquid and disperses it upwards, but also, because there is a gap between the bottom of the turbine 4012 and the top of the first-stage impeller 407, the liquid flow generated by the rotation of the first-stage impeller 407 drives the turbine 4012 to rotate, which in turn drives the second-stage impeller 4011 to rotate through the vertical shaft 4010. The rotation of the second-stage impeller 4011 further enhances the dispersion effect of the Pleurotus ostreatus extract liquid, making the jigging process more thorough and uniform, thereby further improving the jigging separation effect of the Pleurotus ostreatus extract liquid.

[0026] For further details, please refer to [link / reference]. Figure 10 As shown: A sheet metal induction plate 600 is fixedly installed on one side of the jigging plate 403. Two slotted photoelectric switches 700 are fixedly installed on the side of the base 200 near the sheet metal induction plate 600, with their positions corresponding to the positions of the sheet metal induction plate 600. The distance between the two slotted photoelectric switches 700 matches the stroke of the jigging plate 403 as it jumps up and down. The two slotted photoelectric switches 700 are electrically connected to the geared motor 406. When the jigging plate 403 moves up and down, the sheet metal sensing plate 600 moves accordingly. When the jigging plate 403 rises to its highest point or falls to its lowest point, the sheet metal sensing plate 600 passes through the sensing areas of the two slotted photoelectric switches 700. At this time, the slotted photoelectric switches 700 receive the sensing signal and transmit the signal to the geared motor 406. The geared motor 406 starts or stops according to the received signal, ensuring that the geared motor 406 starts every time the jigging plate 403 moves upward and stops every time the jigging plate 403 moves downward.
