Description

Technical Field

[0001] This invention relates to the field of fruit wine brewing technology, specifically to a high-efficiency solid-liquid separation brewing equipment for hawthorn fruit wine. Background Technology

[0002] Hawthorn fruit wine is a type of fruit wine made primarily from hawthorn fruit through fermentation. Its brewing process involves several key steps, including solid-liquid separation of the fruit residue and fermentation liquid, stirring during fermentation, and waste removal. Because hawthorn fruit is rich in pectin, cellulose, and polyphenols, the fruit residue easily absorbs water and swells during fermentation, forming a viscous, pulpy mixture. This makes solid-liquid separation significantly more difficult than for other types of fruit wine.

[0003] Currently, traditional equipment used for hawthorn wine brewing mostly employs a tank structure with a side-entry or top-entry agitator. During the fermentation stage, to promote the dissolution of effective components in the pulp and prevent the pomace from floating and forming a crust, the agitator needs to be activated periodically to stir the materials inside the tank. However, the blades of conventional agitators are usually fixed on the stirring shaft, allowing only a fixed-axis rotation within a single height plane. This limits the stirring range and makes it difficult to effectively agitate the dense layer of pomace deposited at the bottom of the tank. This results in uneven mixing of the materials inside the tank, and the pomace at the bottom, unable to fully contact the fermentation liquid for a long time, suffers from incomplete extraction, leading to raw material waste. Furthermore, pomace soaked for extended periods is prone to spoilage, affecting the flavor and quality of the wine.

[0004] In the solid-liquid separation and slag discharge stages, existing equipment generally employs manual slag removal with an open lid or direct discharge via a bottom valve. Manual slag removal with an open lid is not only labor-intensive and creates a harsh working environment, but also allows a large amount of outside air to enter the tank during the opening process, causing oxidation and browning of the fermentation liquid, resulting in a significant loss of the distinctive bright red color and fruity aroma of hawthorn wine. While the direct discharge via a bottom valve is relatively convenient, the high fiber content, viscosity, and poor flowability of hawthorn slag make it prone to bridging and blockage at the discharge port. Frequent manual stirring or reverse pressurization is required to barely remove the slag, resulting in low efficiency and potential hygiene and safety hazards.

[0005] Furthermore, in existing equipment, the stirring drive and slag discharge drive are usually set up independently, driven by different motors and reduction mechanisms, resulting in a bulky overall structure, high manufacturing costs, and large space occupation. Although some equipment attempts to use the same power source for switching between stirring and slag discharge, the switching mechanism is complex and relies heavily on precision components such as electromagnetic clutches or hydraulic directional valves. This leads to a high failure rate in humid and acidic fermentation environments and makes maintenance difficult. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a high-efficiency solid-liquid separation brewing device for hawthorn fruit wine, solving the problems mentioned in the background art.

[0007] The solution of the present invention to the above-mentioned technical problems is as follows: This invention provides a high-efficiency solid-liquid separation brewing device for hawthorn fruit wine, comprising: The tank body is mounted on a support frame. A stirring mechanism is rotatably installed inside the tank. The stirring mechanism includes a drive shaft, a threaded guide rod disposed at the lower end of the drive shaft, and a stirring blade fitted on the threaded guide rod. The stirring blade and the threaded guide rod are engaged by a helical transmission structure. A locking switching mechanism is connected to the drive shaft. The locking switching mechanism is configured to allow the drive shaft to remain circumferentially locked and allow the stirring blade to rotate downward along the threaded guide rod in a first operating condition, and to lock the circumferential rotation of the stirring blade to drive the drive shaft to rotate synchronously in a second operating condition. A slag discharge drive mechanism is provided at the bottom of the tank body. The slag discharge drive mechanism is connected to the bottom end of the threaded guide rod to drive the slag discharge assembly located above the slag discharge pipe to operate when the drive shaft rotates.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, a fixed seat is provided on the outside of the tank body, and the tank body is mounted on the support through the fixed seat. The bottom end of the support is provided with a support leg, and the support is supported by the support leg. The top of the tank is provided with a manhole, and the tank is provided with an air inlet pipe and an air outlet pipe on both sides of the manhole. The tank body is equipped with a slag discharge pipe at the bottom end, and a blind flange is installed at the bottom end of the slag discharge pipe.

[0010] The beneficial effects of adopting the above-mentioned further solutions are: The tank is mounted on a support frame with legs using a fixed base, creating sufficient operating space between the bottom of the tank and the ground. This facilitates the disassembly and maintenance of the slag discharge pipe and blind flange by operators, while also providing sufficient height for slag discharge, making it convenient for waste slag collection and transfer. A manhole at the top of the tank provides convenient access for operators during loading, cleaning, and maintenance, ensuring the feasibility of equipment maintenance. The air inlet and outlet pipes are symmetrically or separately located on either side of the manhole, ensuring a rational layout, preventing interference between pipelines, and facilitating the even distribution or rapid extraction of gas within the tank. A blind flange is installed at the bottom of the slag discharge pipe, ensuring the overall sealing of the tank during fermentation and stirring. It is only opened when slag discharge is required, effectively preventing the intrusion of outside air and bacteria.

[0011] Furthermore, the locking switching mechanism includes a ratchet, a cylinder, a piston plate, a cone spring, a sleeve, and a transmission mechanism; The tank body is equipped with a retainer, one end of which is fitted with the ratchet, and the other end of which is fitted with the cylinder away from the ratchet. The drive shaft passes through the cage and the cylinder and is connected to the ratchet, so as to restrict the circumferential rotation of the drive shaft under the first working condition by means of the ratchet; The piston plate is elastically mounted inside the cylinder by the conical spring, the conical spring being located below the piston plate, and the piston plate being connected to the transmission mechanism through the sleeve; The intake pipe is connected to the cylinder and is located above the piston plate.

[0012] The beneficial effects of adopting the above-mentioned further solutions are: The ratchet and cylinder are integrated into a single module inside the tank using a retainer, resulting in a compact structure that facilitates pre-assembly and disassembly. The intake pipe is connected above the piston plate, allowing high-pressure gas to directly act on the upper surface of the piston plate. The direction of the thrust is opposite to and collinear with the return force of the cone spring, ensuring efficient power transmission and smooth movement. The ratchet's engagement with the drive shaft, in the first operating condition, unidirectionally locks the drive shaft's rotational freedom, ensuring that the stirring blade rotates only along the threaded guide rod during downward movement without driving the drive shaft, providing the necessary constraint for the passive spiral motion of the stirring blade. The cone spring, positioned below the piston plate, has an elastic coefficient matched to the cylinder stroke, providing sufficient return force to drive the transmission mechanism to switch operating conditions while also buffering the mechanical shock caused by sudden pressure changes, extending the service life of the seals and transmission components.

[0013] Furthermore, the inner surface of the bushing of the stirring blade is provided with a helical slider, and the helical slider and the threaded guide rod form the helical transmission structure; The upper surface of the bushing of the stirring blade is provided with an elastic pin, and a limit plate is connected to the bushing of the stirring blade; A cage is connected to the outside of the multiple stirring blades, and the multiple stirring blades are connected into a whole through the cage.

[0014] The beneficial effects of adopting the above-mentioned further solutions are: A helical slider and threaded guide rod are installed on the inner surface of the stirring blade bushing to forcibly convert the axial linear displacement of the stirring blade into circumferential rotational motion. This allows the stirring blade to achieve high-speed rotation without additional power during descent, greatly simplifying the stirring power mechanism and reducing energy consumption. The elastic pin and limit plate provide a reliable mechanical circumferential locking interface for the stirring blade. The switching between free rotation and locked states of the stirring blade is quickly completed by the extension and retraction of the pin, with fast response and simple control logic. Multiple stirring blades are connected into a whole by a cage, allowing each layer of stirring blades to synchronously perform helical descent or locked rotation movements. This ensures uniform coverage of the stirring force along the axial direction of the tank, avoids localized dead zones in stirring, and enhances the overall rigidity and operational synchronization of the stirring assembly.

[0015] Furthermore, the transmission mechanism includes a pressure cap, a lower pressure ring, and an adapter plate; The pressure cap is connected to the sleeve, and the pressure cap has a pressure plate inside and a slot at the opening of the pressure cap. The stirring blade is sequentially limited by the limiting plate to the lower pressure ring and the adapter plate. The lower pressure ring is located below the pressure cap, and the bottom end of the lower pressure ring is provided with a top rod. The adapter plate has a through hole, and the outer side of the adapter plate has locking teeth that cooperate with the slot. In the second operating condition, the elastic pin is inserted into the through hole, connecting the stirring blade and the adapter plate as one unit, and the stirring blade and the pressure cap are circumferentially fixed by the engagement of the locking teeth and the locking groove.

[0016] The beneficial effects of adopting the above-mentioned further solutions are: The axial thrust of the cylinder is precisely converted into vertical top pressure to control the extension and retraction of the elastic pin through a separate assembly structure of the pressure cap, lower pressure ring, and adapter plate. The push rod at the bottom of the lower pressure ring corresponds one-to-one with the through holes on the adapter plate, ensuring simultaneous force application at multiple points. This allows the elastic pin to smoothly disengage or insert into the through holes, avoiding jamming caused by uneven force. The groove at the opening of the pressure cap engages with the teeth on the outer side of the adapter plate, forming a reliable circumferential rigid connection in the second operating condition. This makes the stirring blade, adapter plate, and pressure cap a single rotating component, thus converting the upward movement of the stirring blade into torque to drive the drive shaft. This purely mechanical clutch and locking structure requires no electrical sensors or solenoid valves, has strong anti-interference capabilities, and operates stably and reliably in humid and acidic fermentation tank environments.

[0017] Furthermore, the slag discharge drive mechanism includes a speed change mechanism, and the slag discharge assembly includes an auger; The speed change mechanism is located inside the tank above the slag discharge pipe, and the bottom end of the threaded guide rod is rotated and supported by the speed change mechanism. The transmission mechanism includes an internal gear ring, a planet carrier, planet gears, and a sun gear fixed to the bottom end of the threaded guide rod; The internal gear ring is supported by a support rod and mounted on the bottom of the tank. The planet carrier is rotatably mounted on the bottom of the internal gear ring. The planet gears are rotatably mounted on the planet carrier, and the planet gears mesh with the internal gear ring and the sun gear respectively for transmission. The auger is connected to the bottom end of the planetary carrier.

[0018] The beneficial effects of adopting the above-mentioned further solutions are: A planetary gear transmission is used as the speed change mechanism, which reduces the input speed and increases the output torque at the bottom of the threaded guide rod before transmitting it to the auger. Due to the planetary gear system's small size, large transmission ratio, and high load-bearing capacity, this speed change mechanism can be compactly arranged within the limited space at the bottom of the tank, without occupying additional tank volume. The auger is directly connected to the bottom of the planetary carrier, allowing the output torque to act directly on the slag discharge spiral blades, avoiding energy loss in intermediate transmission links. When the auger is pushing high-viscosity, high-fiber hawthorn pomace, even if it encounters a sudden increase in resistance, the multi-tooth meshing characteristics of the planetary gear system can effectively distribute the load, preventing the auger from jamming or the drive shaft from breaking, ensuring the continuity of slag discharge operations and the safe operation of the equipment.

[0019] Furthermore, under the first operating condition, the gas introduced through the air inlet pipe pushes the piston plate downward, the pressure cap drives the lower pressure ring downward, and the push rod presses the elastic pin out of the through hole and retracts it into the bushing of the stirring blade, so that the stirring blade rotates and moves downward along the threaded guide rod under the guidance of the spiral transmission structure to perform stirring.

[0020] The beneficial effects of adopting the above-mentioned further solutions are: The piston plate is driven downward by air pressure, which then forces the elastic pin to release the circumferential lock on the stirring blade using a push rod. This process can be completed simply by controlling the opening and closing of the air inlet valve, making operation extremely simple. After the stirring blade loses its circumferential constraint, it moves spirally downward along the threaded guide rod under the combined action of its own gravity and the downward pressure of the cylinder, achieving full-depth three-dimensional mixing from the top to the bottom of the tank. This mixing method not only effectively disperses the fruit pomace suspended in the middle and upper layers, but also agitates the dense fruit pomace layer that has settled to the bottom, making the convective mixing of the entire tank material more thorough and significantly shortening the extraction time of the active ingredients.

[0021] Furthermore, in the second operating condition, the gas in the cylinder is discharged, the cone spring pushes the piston plate to reset, the pressure cap is reset, the elastic pin loses the pressure of the push rod and inserts into the through hole to lock the rotation of the stirring blade and drive the transmission shaft to rotate against the locking force of the ratchet, thereby driving the threaded guide rod to drive the auger to rotate and discharge slag through the speed change mechanism.

[0022] The beneficial effects of adopting the above-mentioned further solutions are: After the cylinder exhausts air, no external power input is required. The elastic potential energy stored in the cone spring alone is enough to push the piston plate back to its original position and cause the push rod to disengage from the elastic pin, thus automatically locking the agitator blade. This design ensures that the slag discharge power comes entirely from the reaction torque generated when the agitator blade attempts to rise as the cone spring is released, achieving an endogenous switching of the power source. The process of the drive shaft rotating to drive the auger to discharge slag is synchronized with the agitator blade resetting process. That is, while the agitator tool is being returned to its original position, the waste slag deposited at the bottom of the tank is being removed simultaneously. The processes are closely linked, and the equipment's operating cycle is more efficient and compact.

[0023] Furthermore, the air outlet pipe is connected to an air storage tank via an external air pump, and the air storage tank is connected to the air inlet pipe via a valve; The cylinder, the sleeve, and the drive shaft are sealed together by a seal.

[0024] The beneficial effects of adopting the above-mentioned further solutions are: High-pressure gases such as carbon dioxide produced during fermentation are extracted and stored instead of being directly emitted, which is both environmentally friendly and achieves secondary energy utilization. The gas storage tank is connected to the air inlet pipe via a valve, allowing operators to use the stored gas to drive the cylinder to complete the stirring action as needed according to the fermentation process, eliminating the need for an additional air compressor and reducing equipment operating energy consumption. Seals are installed between the cylinder, sleeve, and drive shaft to effectively prevent pressurized gas from leaking into the tank, avoiding disturbance or contamination of the fermentation liquid, and also preventing the fermentation liquid from seeping into the cylinder and causing corrosion or jamming, ensuring the long-term stable operation of the pneumatic actuator.

[0025] Furthermore, during fermentation, the high-pressure gas inside the tank is extracted through the gas outlet pipe, creating a negative pressure inside the tank; when stirring is required, the gas in the gas storage tank is introduced into the gas inlet pipe to drive the locking switching mechanism to switch to the first working condition.

[0026] The beneficial effects of adopting the above-mentioned further solutions are: During fermentation, the extraction of gas creates negative pressure, which not only inhibits unwanted microorganisms and promotes the precipitation of dissolved substances from the fruit pomace cells, but also converts the waste gas that would otherwise require energy treatment into a power reserve for stirring operations. When stirring is needed, the gas recovered from the storage tank is used directly for propulsion, forming a self-sufficient closed-loop pneumatic control system. This design makes the gas path management throughout the brewing cycle highly logical and energy-efficient, simplifying the configuration of external power sources, shortening process response time, and achieving intelligent coordination between the fermentation process and mechanical actions.

[0027] As can be seen, the hawthorn fruit wine high-efficiency solid-liquid separation brewing equipment provided by this invention has the following beneficial effects: By designing a locking and switching mechanism consisting of a ratchet, cylinder, piston plate, elastic pin, and transmission mechanism, the interlocking switching between stirring and slag discharge functions under a single power path is achieved. In the first working condition, i.e., the stirring condition, the ratchet locks the transmission shaft, the cylinder presses down to release the circumferential constraint of the stirring blade, and gravity and air pressure cause the stirring blade to rotate spirally. In the second working condition, i.e., the slag discharge condition, the conical spring resets and locks the stirring blade, and the reaction force drives the transmission shaft to rotate, thereby driving the auger to discharge slag. This design cleverly utilizes the same transmission shaft and threaded guide rod, which serve as both the guide support shaft during stirring and the main power shaft during slag discharge, avoiding the drawbacks of traditional equipment that requires separate motors and reducers for the stirrer and slag discharger. Therefore, the overall mechanical structure of the equipment is more compact, the number of parts is significantly reduced, which not only reduces the manufacturing cost and maintenance difficulty of the equipment, but also greatly reduces the footprint of the equipment.

[0028] During the stirring stage, this invention utilizes the gas pressure generated during fermentation. The high-pressure gas produced during fermentation is extracted and stored in a gas storage tank, serving as a power source for driving the cylinder's movement and thus being recycled. This eliminates the need for an additional high-power stirring motor, achieving internal energy recovery and reuse. During stirring, the stirring blades, freed from circumferential locking, descend using a combination of gravitational potential energy and cylinder-assisted thrust. As the stirring blades move downwards along the threaded guide rod, they are forced to rotate at high speed. This combined descent and rotation trajectory effectively cuts and tumbles the fruit pomace and liquid layers from top to bottom within the tank. Compared to traditional stirring methods that rely solely on fixed-axis blade rotation, this invention's spiral descent stirring method more effectively breaks down the suspended stratification and bottom compaction of hawthorn fruit pomace, significantly increasing the contact area and exchange frequency between the solid fruit pomace and liquid juice. This allows for more complete dissolution of phenolic compounds, aroma components, and pigments from the fruit pulp, significantly improving fermentation efficiency and wine quality.

[0029] To address the industry challenge of high fiber content, high viscosity, poor flowability, and bridging blockage at the discharge port of hawthorn pomace, this invention introduces a planetary transmission mechanism between the bottom of the threaded guide rod and the auger. This mechanism utilizes the cooperation of the sun gear, planetary gears, and internal gear ring to convert the high-speed, low-torque input of the drive shaft during stirring and resetting into the low-speed, high-torque output of the planetary carrier. This speed reduction and torque amplification effect gives the auger tremendous rotational thrust, easily squeezing and pushing the high-density, high-viscosity pomace mixture accumulated at the bottom of the tank into the discharge pipe. Even with uncrushed hawthorn seeds or tough peels, the auger can reliably discharge them, greatly improving the smoothness of discharge and the operational reliability of the equipment, avoiding downtime for cleaning due to poor discharge.

[0030] The entire fermentation, stirring, and sludge removal process is carried out in a closed, circulating tank. During fermentation, negative pressure is created inside the tank by extracting gas. This inhibits the activity of aerobic bacteria, reducing the risk of fermentation failure. Furthermore, the negative pressure environment promotes the micro-expansion and rupture of the fruit pomace cell walls, accelerating juice extraction. Since no opening is required during stirring and sludge removal, the contact between outside air and the internal wine is completely isolated, effectively preventing browning and aroma loss caused by oxygen exposure, thus preserving the original fruit aroma and vibrant color of the hawthorn to the greatest extent. In addition, the negative pressure, combined with the forced extrusion of the auger, results in a clearer and purer wine, reducing the load on subsequent filtration processes. This allows for efficient brewing and initial clarification within a single unit.

[0031] At the moment of switching between slag discharge and operation modes, the elastic restoring force of the conical spring not only drives the piston plate to return to its original position, but its flexible elastic release characteristic also acts as a buffer. When the elastic pin re-inserts into the through hole of the adapter plate to lock the stirring blade, the conical spring provides gradual elastic pressure rather than rigid impact, effectively avoiding violent collisions of the transmission components during mode switching. At the same time, the planetary gear transmission system operates smoothly, sharing the sudden load on the auger. This design, combining flexible drive and buffering mechanism, significantly reduces the mechanical wear of the ratchet, drive shaft, and stirring blade helical pair, extends the service life of the core transmission components, and ensures the stability of the equipment in long-term, high-frequency brewing operations.

[0035] 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.

[0036] Please see Figures 1 to 9 As shown, the embodiments provided by the present invention are as follows: Example 1 A high-efficiency solid-liquid separation brewing device for hawthorn fruit wine includes: Tank 1 is mounted on bracket 2; The stirring mechanism 3 is rotatably installed inside the tank 1. The stirring mechanism 3 includes a drive shaft 305, a threaded guide rod 306 disposed at the lower end of the drive shaft 305, and a stirring blade 301 fitted on the threaded guide rod 306. The stirring blade 301 and the threaded guide rod 306 are engaged by a helical transmission structure. A locking switching mechanism is connected to the drive shaft 305. The locking switching mechanism is configured to allow the drive shaft 305 to remain circumferentially locked and allow the stirring blade 301 to rotate downward along the threaded guide rod 306 in a first operating condition, and to lock the circumferential rotation of the stirring blade 301 in a second operating condition to drive the drive shaft 305 to rotate synchronously. The slag discharge drive mechanism is located at the bottom of the tank 1. The slag discharge drive mechanism is connected to the bottom end of the threaded guide rod 306 to drive the slag discharge assembly located above the slag discharge pipe 104 when the drive shaft 305 rotates.

[0037] Example 2 To achieve stable equipment installation and convenient maintenance, optimize tank and pipeline layout, and construct a fermentation gas recycling system, for example, such as Figures 1 to 9 As shown, the present invention also includes: A fixed seat 202 is provided on the outside of the tank body 1. The tank body 1 is mounted on the support 2 through the fixed seat 202. The bottom end of the support 2 is provided with a support leg 201. The support 2 is supported by the support leg 201. The top of the tank body 1 is provided with a manhole 101, and the tank body 1 is provided with an air inlet pipe 102 and an air outlet pipe 103 on both sides of the manhole 101. The tank 1 has a slag discharge pipe 104 at its bottom, with a blind flange installed at the bottom. The tank 1 is mounted on a support 2 with legs 201 via a fixing seat 202, creating sufficient operating space between the bottom of the tank 1 and the ground. This facilitates the disassembly and maintenance of the slag discharge pipe 104 and the blind flange by operators, and also provides a suitable height for slag discharge, facilitating the collection and transfer of waste slag. A manhole at the top of the tank 1 provides convenient access for operators during loading, cleaning, and maintenance, ensuring the feasibility of equipment maintenance. The air inlet pipe 102 and air outlet pipe 103 are symmetrically or separately located on either side of the manhole, ensuring a rational layout and preventing interference between the pipes. This also facilitates the uniform distribution or rapid extraction of gaseous media within the tank. The blind flange installed at the bottom of the slag discharge pipe 104 ensures the overall sealing of the tank 1 during fermentation and stirring. It is only opened when slag discharge is required, effectively preventing the intrusion of external air and bacteria.

[0038] The air outlet pipe 103 is connected to an air storage tank via an external air pump, and the air storage tank is connected to the air inlet pipe 102 via a valve; The cylinder 107, sleeve 111, and drive shaft 305 are sealed with a seal. High-pressure gases such as carbon dioxide generated during fermentation are extracted and stored instead of being directly emitted, which is both environmentally friendly and achieves secondary energy utilization. The gas storage tank is connected to the air inlet pipe 102 via a valve, allowing operators to use the stored gas to drive the cylinder 107 to perform the stirring action as needed during fermentation, eliminating the need for an additional air compressor and reducing equipment operating energy consumption. The seal between the cylinder 107, sleeve 111, and drive shaft 305 effectively prevents pressurized gas in the cylinder 107 from leaking into the tank 1, avoiding disturbance or contamination of the fermentation liquid, and also preventing the fermentation liquid from seeping into the cylinder 107 and causing corrosion or jamming, ensuring the long-term stable operation of the pneumatic actuator.

[0039] High-pressure gas inside tank 1 is extracted through the outlet pipe 103, creating negative pressure inside tank 1. When stirring is required, gas from the storage tank is introduced into the inlet pipe 102 to drive the locking switching mechanism to switch to the first working condition. During fermentation, the extracted gas creates negative pressure, which not only inhibits miscellaneous bacteria and promotes the precipitation of dissolved substances within the fruit pomace cells, but also converts the waste gas that would otherwise require energy treatment into a power reserve for stirring operations. When stirring is needed, the gas recovered from the storage tank is used directly for driving, forming a self-sufficient closed-loop pneumatic control system. This design makes the gas path management throughout the brewing cycle highly logically correlated and energy-efficient, simplifying the configuration of external power sources, shortening the process response time, and realizing intelligent coordination between the fermentation process and mechanical actions.

[0040] Example 3 To achieve reliable mechanical one-way locking and elastic reset switching between stirring mode and slag discharge mode, and to ensure that the drive shaft remains circumferentially fixed when the stirring blade moves downward, for example, such as Figures 1 to 9 As shown, the present invention also includes: The locking switching mechanism includes a ratchet 106, a cylinder 107, a piston plate 108, a cone spring 109, a sleeve 111, and a transmission mechanism 110; The tank body 1 is provided with a retainer 105 inside. A ratchet 106 is installed at one end of the retainer 105, and a cylinder 107 is installed at the end of the retainer 105 away from the ratchet 106. The drive shaft 305 passes through the cage 105 and the cylinder 107 and is connected to the ratchet 106 so as to limit the circumferential rotation of the drive shaft 305 under the first working condition by means of the ratchet 106; The piston plate 108 is elastically mounted in the cylinder 107 by a cone spring 109. The cone spring 109 is located below the piston plate 108. The piston plate 108 is connected to the transmission mechanism 110 through a sleeve 111. The intake pipe 102 is connected to the cylinder 107 and is located above the piston plate 108. The ratchet 106 and cylinder 107 are integrated into a single module inside the tank 1 using a retainer 105, resulting in a compact structure that facilitates pre-assembly and disassembly. Connecting the intake pipe 102 above the piston plate 108 allows high-pressure gas to directly act on the upper surface of the piston plate 108. The direction of the thrust is opposite to and collinear with the return force of the cone spring 109, ensuring efficient power transmission and smooth movement. The ratchet 106's engagement with the drive shaft 305, under the first operating condition, can unidirectionally lock the rotational freedom of the drive shaft 305. This ensures that when the stirring blade 301 moves downward, it can only rotate along the threaded guide rod 306 without causing the drive shaft 305 to rotate, providing the necessary constraint for the passive spiral motion of the stirring blade 301. The cone spring 109 is located below the piston plate 108. Its elastic coefficient matches the stroke of the cylinder 107. It can provide sufficient reset force to drive the transmission mechanism 110 to switch working conditions, and can also buffer the mechanical impact caused by sudden changes in air pressure, thus extending the service life of the seals and transmission pairs.

[0041] Example 4 To precisely transmit the axial driving force of the cylinder to the circumferential locking structure of the stirring blade, and to achieve smooth insertion and disengagement of the elastic pin in the through hole, thus forming a reliable mechanical clutch and circumferential fixed connection, for example, such as Figures 1 to 9 As shown, the present invention also includes: The transmission mechanism 110 includes a pressure cap 114, a lower pressure ring 115, and an adapter plate 116; The pressure cap 114 is connected to the sleeve 111. The pressure plate 112 is provided inside the pressure cap 114, and the opening of the pressure cap 114 is provided with a slot 113. The mixing blade 301 is sequentially limited by the limiting plate 308, with a lower pressure ring 115 and a transition plate 116. The lower pressure ring 115 is located below the pressure cap 114, and a top rod 119 is provided at the bottom end of the lower pressure ring 115. The adapter plate 116 has a through hole 117, and the outer side of the adapter plate 116 has a locking tooth 118 that mates with the locking groove 113. In the second operating condition, the elastic pin 309 is inserted into the through hole 117, connecting the stirring blade 301 and the adapter plate 116 as a whole. Through the engagement of the locking teeth 118 and the locking groove 113, the stirring blade 301 and the pressure cap 114 are circumferentially fixed. The separate assembly structure of the pressure cap 114, the lower pressure ring 115, and the adapter plate 116 precisely converts the axial thrust of the cylinder 107 into a vertical top pressure that controls the extension and retraction of the elastic pin 309. The push rod 119 at the bottom of the lower pressure ring 115 corresponds one-to-one with the through hole 117 on the adapter plate 116, ensuring simultaneous force application at multiple points. This allows the elastic pin 309 to smoothly disengage or insert into the through hole 117, avoiding jamming caused by uneven force. The slot 113 at the opening of the cap 114 engages with the teeth 118 on the outer side of the adapter plate 116, forming a reliable circumferential rigid connection in the second operating condition. This allows the stirring blade 301, the adapter plate 116, and the cap 114 to form a single rotating component, thereby converting the upward tendency of the stirring blade 301 into torque that drives the drive shaft 305 to rotate. This purely mechanical clutch and locking structure requires no electrical sensors or solenoid valve control, has strong anti-interference capabilities, and operates stably and reliably in humid and acidic fermenter environments.

[0042] Example 5 To achieve passive high-speed rotation of the stirring blades during axial displacement and synchronous linkage of multiple stirring blades, and to provide deceleration and torque-increasing power output during the slag discharge process to prevent slag discharge blockage, for example, such as Figures 1 to 9 As shown, the present invention also includes: The inner surface of the bushing of the stirring blade 301 is provided with a spiral slider 310, and the spiral slider 310 and the threaded guide rod 306 form a spiral transmission structure; The upper surface of the bushing of the stirring blade 301 is provided with an elastic pin 309, and a limit plate 308 is connected to the bushing of the stirring blade 301. Multiple stirring blades 301 are connected to a cage 302 on their outer sides, and the multiple stirring blades 301 are connected into a whole through the cage 302. A spiral slider 310 is set on the inner surface of the bushing of the stirring blade 301, which cooperates with the threaded guide rod 306 to forcibly convert the axial linear displacement of the stirring blade 301 into circumferential rotational motion. This allows the stirring blade 301 to achieve high-speed self-rotation without additional power during descent, greatly simplifying the stirring power mechanism and reducing energy consumption. The setting of the elastic pin 309 and the limit plate 308 provides a reliable mechanical circumferential locking interface for the stirring blade 301. The switching between the free rotation state and the locked state of the stirring blade 301 can be quickly completed by the extension and retraction of the pin. The response speed is fast and the control logic is simple. The multiple stirring blades 301 are connected into a whole through the cage 302, so that each layer of stirring blades 301 can perform spiral descent or locked rotation actions synchronously. This ensures that the stirring force is evenly covered in the axial direction of the tank 1, avoids the occurrence of local stirring dead zones, and enhances the overall rigidity and operational synchronization of the stirring assembly.

[0043] The slag discharge drive mechanism includes a speed change mechanism 304, and the slag discharge assembly includes an auger 303; The speed change mechanism 304 is located inside the tank 1 above the slag discharge pipe 104, and the bottom end of the threaded guide rod 306 is rotated and supported by the speed change mechanism 304. The transmission mechanism 304 includes an internal gear ring 314, a planet carrier 311, planet gears 313, and a sun gear 307 fixed to the bottom end of the threaded guide rod 306. The internal gear ring 314 is supported by the support rod 312 and mounted on the bottom of the tank body 1. The planet carrier 311 is rotatably mounted on the bottom of the internal gear ring 314. The planet gear 313 is rotatably mounted on the planet carrier 311, and the planet gear 313 meshes with the internal gear ring 314 and the sun gear 307 respectively for transmission. The auger 303 is connected to the bottom end of the planetary carrier 311, and uses planetary gear transmission as the speed change mechanism 304. This mechanism reduces the input speed and increases the output torque from the bottom of the threaded guide rod 306 before transmitting it to the auger 303. Because the planetary gear system 313 has the characteristics of small size, large transmission ratio, and strong load-bearing capacity, this speed change mechanism 304 can be compactly arranged in the limited space at the bottom of the tank 1 without occupying additional tank volume. The auger 303 is directly connected to the bottom end of the planetary carrier 311, allowing the output torque to act directly on the slag discharge spiral blades, avoiding energy loss in intermediate transmission links. When the auger 303 is pushing high-viscosity, high-fiber hawthorn pomace, even if there is a sudden increase in instantaneous resistance, the multi-tooth meshing characteristics of the planetary gear system 313 can effectively distribute the load, preventing the auger 303 from jamming or the drive shaft 305 from breaking, ensuring the continuity of slag discharge operations and the safe operation of the equipment.

[0044] Example 6 To clarify the specific linkage control method of the equipment under the first and second operating conditions, and to achieve efficient connection and automatic switching between the mixing and slag discharge processes, for example, such as... Figures 1 to 9 As shown, the present invention also includes: In the first operating condition, gas is introduced through the air inlet pipe 102, pushing the piston plate 108 downward. The pressure cap 114 drives the lower pressure ring 115 downward, and the push rod 119 pushes the elastic pin 309 out of the through hole 117 and retracts it into the bushing of the stirring blade 301. This allows the stirring blade 301 to rotate and move downward along the threaded guide rod 306 under the guidance of the spiral drive structure, thus performing stirring. The piston plate 108 is driven downward by air pressure, and the push rod 119 forcibly releases the circumferential lock of the elastic pin 309 on the stirring blade 301. This process can be completed simply by controlling the opening and closing of the air inlet valve, making the operation extremely simple. After the stirring blade 301 loses its circumferential constraint, it moves downward spirally along the threaded guide rod 306 under the combined action of its own gravity and the downward pressure of the cylinder 107, achieving full-depth three-dimensional stirring from the top to the bottom of the tank 1. This stirring method can not only effectively disperse the fruit pomace suspended in the middle and upper layers, but also turn over the dense fruit pomace layer that has settled to the bottom, making the convection mixing of the entire tank of materials more thorough and significantly shortening the extraction time of the active ingredients.

[0045] In the second operating condition, the gas in cylinder 107 is discharged, the conical spring 109 pushes the piston plate 108 to reset, the pressure cap 114 resets, and the elastic pin 309, freed from the pressure of the push rod 119, inserts into the through hole 117 to lock the rotation of the stirring blade 301 and drive the transmission shaft 305 to rotate against the locking force of the ratchet 106. This, in turn, drives the threaded guide rod 306 to drive the auger 303 to rotate and discharge slag through the speed change mechanism 304. After the gas in cylinder 107 is discharged, no external power input is required; the elastic potential energy stored in the conical spring 109 alone is sufficient to push the piston plate 108 to reset and drive the push rod 119 to disengage from the elastic pin 309, thus completing the automatic locking of the stirring blade 301. This design ensures that the slag discharge power comes entirely from the reaction torque generated when the stirring blade 301 attempts to rise as the conical spring 109 is released, achieving an endogenous switching of the power source. The process of the drive shaft 305 rotating to drive the auger 303 to discharge slag is carried out simultaneously with the resetting process of the stirring blade 301. That is, while the stirring tool is being returned to its original position, the waste slag deposited at the bottom of the tank is being removed at the same time. The process is closely connected, and the working rhythm of the equipment is more efficient and compact.

[0046] Working principle: Before fermenting the hawthorn pomace, ensure that tank 1 is sealed, with the bottom discharge pipe 104 closed by a blind flange. Place the hawthorn raw material to be fermented into tank 1 through the manhole 101 at the top. Once fermentation begins, the decomposition of the pomace generates a large amount of gas, causing the pressure inside the tank to rise. At this time, the control system activates an external air pump, continuously extracting the high-pressure gas from tank 1 through the air outlet pipe 103, and storing the extracted gas in an external gas storage tank. As the gas is discharged, a negative pressure environment is created inside tank 1. This negative pressure not only facilitates the rapid separation of juice and pomace but also inhibits the growth of unwanted bacteria, improving the fermentation quality of the fruit wine. The extracted gas is temporarily stored in the gas storage tank as a power source for recycling in subsequent stirring processes.

[0047] As fermentation progresses, the fruit residue in tank 1 will gradually stratify and settle. When solid-liquid mixing and stirring are required to promote the release of effective components, the equipment switches to the first operating mode, namely the stirring mode.

[0048] When starting under this operating condition, the valve connecting the air tank and the air intake pipe 102 is opened. High-pressure gas enters the cylinder 107 through the air intake pipe 102 and acts on the space above the piston plate 108. Driven by the air pressure, the piston plate 108 moves downward against the elastic resistance of the cone spring 109 below it. The downward movement of the piston plate 108 transmits the thrust to the pressure cap 114 in the transmission mechanism 110 through the sleeve 111.

[0049] When the pressure cap 114 is pressed, it moves downward, thereby pushing the lower pressure ring 115 located below it. The push rod 119 at the bottom of the lower pressure ring 115 then applies force to the elastic pin 309 on the upper surface of the agitator blade 301 bushing. The push rod 119 forcibly pushes the elastic pin 309 out of the through hole 117 of the adapter plate 116, causing the elastic pin 309 to retract into the bushing of the agitator blade 301. At this time, the circumferential locking relationship between the agitator blade 301, the adapter plate 116, and the pressure cap 114 is released.

[0050] Meanwhile, since one end of the drive shaft 305 is connected to the ratchet 106 on the cage 105, the one-way locking characteristic of the ratchet 106 restricts the circumferential rotation of the drive shaft 305. Therefore, when the stirring blade 301 loses its circumferential constraint, under the combined action of its own gravity and the downward thrust of the cylinder 107, the stirring blade 301 tends to move downward along the axial direction. Under the helical transmission cooperation between the spiral slider 310 on the inner surface of the stirring blade 301 bushing and the threaded guide rod 306, the downward movement of the stirring blade 301 is forcibly converted into a spiral motion of rotating and descending. During this process, multiple stirring blades 301 connected as one unit by the cage 302 rotate and move downward within the tank 1, effectively agitating and churning the fruit pomace liquid at different depths in the tank, breaking up the sedimentation and compaction of the fruit pomace, and making the solid and liquid phases remix uniformly.

[0051] After one mixing cycle is completed, the equipment switches to the second operating mode, namely the slag discharge mode. At this time, the air inlet pipe 102 is closed, and the compressed gas inside the cylinder 107 is discharged outward through the valve. After the air pressure is unloaded, the previously compressed cone spring 109 begins to release its elastic potential energy, pushing the piston plate 108 to return to its original position along the inner wall of the cylinder 107.

[0052] The resetting action of the piston plate 108 causes the pressure cap 114 to move upward through the sleeve 111, separating the pressure cap 114 from the lower pressure ring 115. This causes the push rod 119 at the bottom of the lower pressure ring 115 to release its pressing force on the elastic pin 309. The elastic pin 309 automatically pops out under the action of its internal elastic element and re-inserts into the through hole 117 of the adapter plate 116. This action reconnects the stirring blade 301 and the adapter plate 116 into a whole. At the same time, the retaining teeth 118 on the outside of the adapter plate 116 engage with the retaining groove 113 at the opening of the pressure cap 114, thereby completely locking the circumferential rotational freedom of the stirring blade 301 through the connection structure between the pressure cap 114 and the sleeve 111.

[0053] Since the stirring blade 301 can no longer rotate relative to the threaded guide rod 306 at this point, and the restoring force of the cone spring 109 gives the stirring blade 301 an upward displacement tendency, the circumferential reaction force generated by this tendency forces the drive shaft 305 to overcome the locking force of the ratchet 106 and begin to rotate synchronously. At this point, the power transmission path changes, switching from the downward rotation of the stirring blade 301 to the overall rotation of the drive shaft 305.

[0054] The rotation of the drive shaft 305 drives the threaded guide rod 306 at its lower end to rotate synchronously. The sun gear 307, fixed at the bottom end of the threaded guide rod 306, starts to rotate as the driving gear, and the planet gears 313 meshing with it perform a combined motion of revolution and rotation under the constraint of the fixed internal gear ring 314. The revolution of the planet gears 313 drives the planet carrier 311 to rotate. The planet carrier 311, as the output end, has a significantly lower speed than the speed at the input end of the drive shaft 305, and the torque is correspondingly increased, forming a planetary transmission mechanism 304 that reduces speed and increases torque.

[0055] The rotation of the planetary carrier 311 directly drives the auger 303 connected to its bottom to rotate. The spiral blades of the auger 303 guide the waste residue accumulated at the bottom of the tank 1 due to gravity settling and the agitation process to the central slag discharge area, and forcefully squeeze and push it into the slag discharge pipe 104. By periodically opening the blind flange at the bottom of the slag discharge pipe 104, the operator can efficiently clean the waste residue without interrupting the sealed environment of the tank 1.
