Description

Technical Field

[0001] The invention relates to the technical field of food additive production equipment, in particular to a constant-temperature fermentation tank for an enzyme preparation used as a food additive. Background Art

[0002] As an important food additive, enzyme preparations are widely used in the food industry. In the production process of enzyme preparations, fermentation is one of the key links. The fermentation process has extremely strict requirements on temperature. Temperature fluctuations will significantly affect the activity and fermentation efficiency of the enzyme, thereby affecting the quality and yield of the enzyme preparation.

[0003] In the prior art, such as Chinese patent publication number: CN111925916B, a production device for a solid-state fermentation enzyme preparation and a working method thereof are disclosed, including a fermentation tank, wherein the four corners of the bottom of the fermentation tank are fixedly connected to support legs, and the two sides of the bottom of the fermentation tank are symmetrically provided with support platforms, and the two support platforms are symmetrically fixedly connected to the supporting plates on the opposite sides of the tops of the two support platforms, and the other sides of the two support platforms are symmetrically provided with fixed plates, and the top and bottom of the fixed plates close to the supporting plates are symmetrically fixedly connected with positioning columns, and the middle of one side of the fixed plate is fixedly connected with a shock-absorbing spring, and the middle of the other side of the fixed plate is provided with a fixing bolt, and the center of the inner wall of the bottom of the fermentation tank is fixedly connected with a support platform. The present invention heats the reaction liquid at a constant temperature by an electric heating plate to accelerate the fermentation reaction of the reaction liquid, drives the rotating shaft to rotate by a driving motor, drives the rotating column to rotate on the support platform, and the stirring column stirs the reaction liquid to make the heated liquid evenly diffuse.

[0004] In the prior art, existing fermentation tanks used for enzyme preparation production have certain deficiencies in constant temperature control. Although some fermentation tanks are equipped with temperature control systems and are insulated by setting corresponding insulation structures on the outside of the fermentation tanks, when performing insulation operations, they mostly rely on the circulation of hot water to achieve insulation. When the hot water circulates to the rear section, it is easy for the water temperature in the rear section to drop due to excessive heat exchange between the water flowing in the front and the outside or the fermentation product, which will affect the insulation operation of the fermentation tank.

[0005] Therefore, we propose a constant temperature fermentation tank for enzyme preparation of food additives in order to solve the problems raised in the above background technology. Summary of the Invention

[0006] The object of the present invention is to provide a constant temperature fermentation tank for enzyme preparations for food additives, so as to solve the problem that although the fermentation tank proposed in the above background technology is provided with a temperature control system and is insulated by arranging a corresponding insulation structure on the outside of the fermentation tank, when it is performing the insulation operation, it mostly relies on the circulation of hot water to achieve insulation. When the hot water circulates to the rear section, it is easy to cause the temperature of the water in the rear section to drop due to excessive heat exchange between the water flowing in the front section and the outside or the fermented material, which will affect the insulation operation of the fermentation tank.

[0009] Preferably, a leg assembly is fixedly connected to the bottom end surface of the support mechanism, and there are two leg assemblies in total. The two leg assemblies are fixedly connected in a longitudinal array at the front and rear sides of the bottom end surface of the support mechanism. A fermentation assembly of a horizontal fermentation tank structure is fixedly connected to the inner side of the support mechanism, and a discharge pipe is fixedly connected to the bottom end of the outer peripheral surface of the fermentation assembly.

[0010] Preferably, a feed pipe is fixedly connected to the top of the outer peripheral surface of the fermentation component, and the feed pipe and the discharge pipe are staggered. A servo motor A is fixedly connected to the left end surface of the fermentation component, and a screw is installed on the right output shaft of the servo motor A.

[0011] Preferably, the servo motor A and the spiral member together form a stirring and feeding structure, and the circulation mechanism is a spiral structure. There are two circulation mechanisms in total, and the two circulation mechanisms are arranged in a linear array on the left and right sides of the outer surface of the fermentation component.

[0012] Preferably, the front end of the circulation mechanism is fixedly connected with a liquid inlet pipe and a liquid outlet pipe in a linear array, the liquid inlet pipe is connected with the liquid outlet pipe through the circulation mechanism, and the outer sides of the liquid inlet pipe and the liquid outlet pipe are fixedly connected with a control valve A.

[0013] Preferably, the front ends of the two liquid inlet pipes are both installed with connecting elbows through flanges, the front ends of the two liquid outlet pipes are both fixedly connected to connecting branches through flanges, and a hot water pipe is fixedly connected to the front end surface of the constant temperature heating tank. The hot water pipe is connected to the two connecting elbows.

[0014] Preferably, a return pipe is fixedly connected to the front end of the outer periphery of the constant temperature heating tank, the return pipe is connected to two connecting branches, and the outer sides of the return pipe and the hot water pipe are fixedly connected to an extraction pump.

[0015] Preferably, the middle section of the circulation mechanism is fixedly connected to a taking-over mechanism, a control valve B is installed inside the taking-over mechanism, a temperature measuring component is fixedly connected to the front end surface of the control valve B, and when the circulation mechanism is sleeved on the outside of the fermentation component, the temperature measuring component is in a state of contact with the outer wall of the fermentation component for detection.

[0016] Preferably, an extraction tube and a liquid pumping tube are fixedly connected in a linear array on the outer peripheral surface of the circulation mechanism. The extraction tube and the liquid pumping tube are separated by a control valve B. The extraction tube is used to extract liquid from the interior of the circulation mechanism, and the liquid pumping tube is used to supply liquid to the rear section of the circulation mechanism. The interior of the extraction tube and the liquid pumping tube are both fixedly connected with a spring component, and one end of the spring component is fixedly connected with a baffle assembly and a plug assembly. The baffle assembly and the plug assembly are squeezed and discharged through the injection tube.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is used, the mechanical positioning structure of the transmission screw and the slider is used to ensure that the injection pipe and the circulation mechanism are accurately docked, and the mechanical pumping force of the drainage pump is used to force the hot water to flow in a directional manner, forming a mechanical circulation link of "front-end high-pressure injection and end-end negative pressure reflux". Compared with the traditional gravity circulation, this design eliminates the hysteresis of fluid self-flow through rigid mechanical connection, significantly improves the hot water flow rate in the circulation mechanism, ensures that the temperature uniformity of the periphery of the fermentation component is significantly improved, and avoids enzyme protein denaturation and inactivation due to local overheating.

[0018] 2. When the present invention is used, the metal abutment rod of the temperature measuring component is in rigid contact with the outer wall of the fermentation component through the spring pin, and the temperature change is directly converted into mechanical displacement to drive the sliding valve action of the control valve B: when the temperature exceeds the threshold, the mechanical connecting rod pushes the sliding valve to open the extraction tube, and the high-temperature section fluid is discharged by the suction of the drainage pump; the low-temperature section is injected with preheated fluid through the mechanical connection between the pump liquid pipe and the hot water pipe. The conical sealing structure of the spring part and the plug assembly realizes leak-free docking through the mechanical extrusion of the injection pipe. The entire system can complete the entire process of "temperature measurement-conduction-regulation" without electricity, and can still maintain the temperature control function in the event of power outage or control system failure, meeting the stringent requirements for equipment reliability in food production.

[0019] 3. When the present invention is used, the long axis structure of the horizontal fermentation component is combined with the variable pitch blade design of the spiral component to generate a compound motion of "axial pushing + radial stirring" during mechanical rotation: the axial thrust causes the material to move along the entire length of the tank body, and the 45° inclination angle of the radial blade forces the material to produce tumbling shear. At the same time, the spiral channel of the circulation mechanism applies a reverse circumferential torque to the tank body, forming a mechanical coupling effect of "positive rotation of the stirring shaft and slight reverse vibration of the tank body", further tearing the material agglomerates, and the mixing uniformity is naturally guaranteed by the mechanical structure design, without relying on sensor feedback adjustment.

[0020] 4. When the present invention is used, a fully mechanical positioning system is constructed by cooperating the dovetail groove of the transmission screw and the slider, and the screw transmission of the servo push rod and the sliding block. The screw part and the servo motor A are driven by the rigid gears of the gear reducer, which avoids the risk of slipping of the belt drive and can still maintain stable torque output in a high-humidity fermentation environment. The pure mechanical connecting rod transmission between the temperature measuring component and the control valve B eliminates the hidden dangers of electrical faults such as electromagnetic interference and line aging, and is particularly suitable for the complex electromagnetic environment of food processing workshops.

[0021] 5. When the present invention is in use, the support mechanism and the base mechanism can be quickly disassembled and assembled through the bolt group, and the fermentation component can be lifted off as a whole for deep cleaning; the liquid inlet pipe and the liquid outlet pipe of the circulation mechanism adopt a clamp-type quick-release flange, and the pipeline separation can be completed within seconds, which is convenient for regular removal of biofilm on the inner wall of the pipeline. The mechanical quick-plug interface of the injection pipe and the drainage pipe adopts a spring locking structure. During maintenance, you only need to press the lock to disconnect it, and no tools are required. The bearing seat of the spiral part adopts a split design. The bearing assembly can be disassembled by loosening the bolts. The replacement cycle is shortened from hours of the traditional integral structure to minutes, which significantly improves the equipment utilization rate.

[0022] 6. When the present invention is in use, mechanical limit blocks are set at both ends of the transmission screw. When the moving component reaches the limit position, the limit block is in rigid contact with the retaining edge of the support mechanism to prevent overload damage; the shaft of the spiral component is equipped with a shear pin overload protection device. When the viscosity of the material is too high and the torque exceeds the set value, the shear pin breaks and cuts off the power transmission to avoid motor burning. The spiral pipe and the connecting mechanism of the circulation mechanism adopt a dual fixing process of expansion + welding to extend the service life of the equipment to more than years. The spring parts are treated with anti-corrosion coating, and the stainless steel material of the plug assembly reduces the occurrence of rust. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] For example 1, please refer to Figures 1-8 As shown, the present invention provides a technical solution: a constant temperature fermentation tank for enzyme preparation for food additives, comprising a bottom plate mechanism 1, a bracket assembly 101 fixedly connected to the top surface of the bottom plate mechanism 1, and a constant temperature heating tank 1011 with an electric heating structure placed inside the bottom plate mechanism 1 and the bracket assembly 101; The left side of the bracket assembly 101 is fixedly connected to the support mechanism 2, and a transverse groove is provided on the rear side of the support mechanism 2. A servo motor B3 is installed on the left end face of the support mechanism 2. A transmission screw 301 is installed on the right output shaft of the servo motor B3 through a coupling. A moving assembly 3011 is installed inside the transverse groove on the rear side of the support mechanism 2. A screw hole matching the transmission screw 301 is provided inside the moving assembly 3011, and sliders 3012 with raised structures are fixedly connected to the upper and lower sides of the moving assembly 3011. A longitudinal groove is provided inside the moving component 3011, and a longitudinal servo push rod 3013 is fixedly connected to the interior of the longitudinal groove. A sliding block 3014 is fixedly connected to the front end of the servo push rod 3013. Two connecting plates 3015 are fixedly connected to the upper and lower sides of the sliding block 3014 in opposite directions. The inner sides of the two connecting plates 3015 are fixedly connected to injection pipes 3016. The outer circumference of the injection pipe 3016 is provided with injection holes 3017 in a ring array. One side is also fixedly connected with a drainage pipe 3018, and the outside of the drainage pipe 3018 is fixedly connected with a drainage pump 3019. The side of the drainage pipe 3018 away from the injection pipe 3016 is connected to the constant temperature heating tank 1011. There are two drainage pipes 3018. The drainage pipe 3018 on the lower side is used to obtain hot water from the inside of the constant temperature heating tank 1011, and the drainage pipe 3018 on the upper side is used to extract cold water from the inside of the circulation mechanism 4 and return it to the constant temperature heating tank 1011. The outer peripheral surface of the constant temperature heating tank 1011 A cold water inlet pipe 1012 for feeding liquid into the constant temperature heating tank 1011 is fixedly connected on the right side. The support mechanism 2 is a rectangular frame structure. A leg assembly 201 is fixedly connected to the bottom end face of the support mechanism 2. There are two leg assemblies 201 in total. The two leg assemblies 201 are fixedly connected in a longitudinal array at the front and rear sides of the bottom end face of the support mechanism 2. A fermentation assembly 2011 of a horizontal fermentation tank structure is fixedly connected to the inner side of the support mechanism 2. A discharge pipe 2012 is fixedly connected to the bottom end of the outer peripheral surface of the fermentation assembly 2011.

[0026] In this embodiment, when in use, the constant temperature heating tank 1011 is injected with liquid medium through the cold water inlet pipe 1012, the internal electric heating structure is started, and the liquid is stored in the tank after being heated. After the servo motor B3 is energized, it drives the transmission screw 301 to rotate. The moving component 3011 engages with the transmission screw 301 due to the internal screw hole, and moves horizontally along the horizontal groove on the rear side of the support mechanism 2 through the upper and lower sliders 3012 until the injection pipe 3016 is aligned with the front end of the circulation mechanism 4. The lower drainage pipe 3018 is connected to the constant temperature heating tank 1011. After the drainage pump 3019 is started, the heated liquid in the tank is sprayed into the inlet end of the circulation mechanism 4 through the injection holes 3017 of the annular array on the outer periphery of the injection pipe 3016, forming a high-pressure jet to push the liquid forward; The temperature of the liquid at the end of the circulation mechanism 4 is reduced after heat exchange, and the upper drainage pipe 3018 draws the low-temperature liquid back to the constant temperature heating tank 1011 through the drainage pump 3019 for reheating, realizing a closed circulation path of "front-end heat injection-end cold return". The core of the mechanical connection: the transmission screw 301 and the moving component 3011 are threaded together to achieve lateral positioning, and the servo push rod 3013 pushes the sliding block 3014 to adjust the longitudinal height of the injection pipe 3016 to ensure alignment with the interface of the circulation mechanism 4; the drainage pipe 3018 is rigidly connected to the constant temperature heating tank 1011 and the injection pipe 3016 through a flange to ensure fluid sealing.

[0027] Example 2, as Figures 1-6 As shown, a feed pipe 2013 is fixedly connected to the top of the outer peripheral surface of the fermentation component 2011, and the feed pipe 2013 and the discharge pipe 2012 are staggered. A servo motor A2014 is fixedly connected to the left end surface of the fermentation component 2011, and a screw 2015 is installed on the right output shaft of the servo motor A2014. The servo motor A2014 and the screw 2015 together constitute a stirring and feeding structure, and the circulation mechanism 4 is a spiral structure. There are two circulation mechanisms 4. The two circulation mechanisms 4 are in a linear array and are sleeved on the left and right sides of the outer peripheral surface of the fermentation component 2011. The front end of the circulation mechanism 4 is fixedly connected to the liquid inlet pipe 401 and the liquid outlet pipe 4011 in a linear array. The liquid inlet pipe 401 is connected to the liquid outlet pipe 4011 through the circulation mechanism 4. The outside of the liquid inlet pipe 401 and the liquid outlet pipe 4011 are fixedly connected to the control valve A4012.

[0028] In this embodiment, when in use, the fermentation assembly 2011 is arranged horizontally with the horizontal axis as the center, and is bolted to the C-shaped bracket of the support mechanism 2 through flanges at both ends. The leg assembly 201 at the bottom of the bracket adopts an adjustable foot structure, and the horizontality of the tank body is fine-tuned by rotating the screw. The servo motor A2014 is fixed to the left end of the support mechanism 2 through an L-shaped cast iron bracket, and its output shaft is rigidly connected to the solid shaft of the screw member 215 through an elastic coupling. The coupling has a built-in cross sliding block structure. The right end of the screw member 2015 is supported by a sliding bearing seat, and the bearing seat and the tank end cover are matched with a stopper. The feed pipe 2013 and the discharge pipe 2012 are diagonally distributed and are both connected to the tank body with flanges. The feed pipe 2013 has a built-in gate valve, which is opened and closed by a handwheel driving the screw nut mechanism; the discharge pipe 2012 has a built-in ball valve, and the valve stem is linked to the worm gear reducer. The opening can be adjusted by a large angle rotation through the handle. An elliptical manhole is opened on the top of the tank body, and the manhole cover is connected to the tank body by a hinge. When closed, the rubber sealing ring is compressed by the surrounding bolts to achieve sealing. The servo motor A2014 is decelerated by a gear reducer. The reducer input and output shafts are driven by helical gears. The reducer housing and motor bracket are fixed with locating pins to ensure the coaxiality of the shaft system. The surface of the screw 2015 shaft is rolled with anti-slip grooves, forming an interference fit with the keyway of the blade inner hole. It is fixed with a set screw to prevent the blade from axial movement. When the motor is started, the screw 2015 rotates clockwise, the blades in the feeding section push the material to the right, and the serrated blades in the mixing section generate centrifugal force as their diameter increases, throwing the material toward the tank wall. At the same time, the double-lead structure forces the material to be axially compressed, forming an extrusion force to break up the agglomerates; the left-handed blades in the discharge section push the material on the right side back to the left, forming an offset with the pushing force of the feeding section, and the material forms a vortex zone in the middle of the tank, extending the retention time; When hot water flows into the circulation mechanism 4 from the liquid inlet pipe 401, the spiral pipe forces the fluid to generate a clockwise swirl. The friction of the fluid on the inner wall of the pipe forms a counterclockwise reaction torque, which is transmitted to the tank body through the clamp, causing the tank body to oscillate slightly. This oscillation forms a mechanical coupling with the rotation of the spiral member 2015: the oscillation of the tank body causes the material to produce radial displacement, and the axial thrust of the spiral blades maintains the axial flow of the material. The two work together to form a compound motion of "axial pushing + radial oscillation", which prevents the material from forming stratification in the tank. The bracket of the support mechanism 2 is connected to the bottom plate mechanism 1 by bolts, and can be lifted away from the tank body as a whole when dismantling; the bearing seat of the spiral member 215 is a split structure, and the upper cover can be removed by loosening the top bolts to remove the shaft system assembly; the clamp of the circulation mechanism 4 adopts a quick-release retaining spring design, which can be released by pressing the retaining spring, making it easy to dismantle and clean the pipeline; The flange connections of the feed pipe 2013 and the discharge pipe 2012 are both provided with guide grooves to prevent residual materials from dripping during disassembly; a scraper is provided on the inside of the manhole cover, which can automatically scrape off materials adhering to the tank wall when opened, reducing the cleaning workload.

[0029] Example 3, as Figure 5-Figure 8As shown, the front ends of the two liquid inlet pipes 401 are both installed with connecting elbows 4013 through flanges, the front ends of the two liquid outlet pipes 4011 are both fixedly connected to connecting branches 4014 through flanges, and a hot water pipe 4015 is fixedly connected to the front end surface of the constant temperature heating tank 1011. The hot water pipe 4015 is connected to the two connecting elbows 4013. The front end of the outer periphery of the constant temperature heating tank 1011 is fixedly connected to a return pipe 4016, which is connected to the two connecting branches 4014. The outsides of the return pipe 4016 and the hot water pipe 4015 are both fixedly connected to an extraction pump 4017. The middle section of the circulation mechanism 4 is fixedly connected to a connecting mechanism 5. The control valve B501 is installed inside the connecting mechanism 5. The front end surface of the control valve B501 is fixedly connected to a temperature measuring component 5011. When the circulation mechanism 4 is sleeved on the outside of the fermentation component 2011, the temperature measuring component 5011 is in contact with the fermentation component 2011. In the detection state of the outer walls abutting each other, an extraction tube 5012 and a pump liquid tube 5013 are fixedly connected in a linear array on the outer peripheral surface of the circulation mechanism 4, and the extraction tube 5012 and the pump liquid tube 5013 are separated by a control valve B501. The extraction tube 5012 is used to extract liquid from the interior of the circulation mechanism 4, and the pump liquid tube 5013 is used to supply liquid to the rear section of the circulation mechanism 4. The interior of the extraction tube 5012 and the pump liquid tube 5013 are both fixedly connected with a spring component 5014, and one end of the spring component 5014 is fixedly connected with a baffle assembly 5015 and a plug assembly 5016. The baffle assembly 5015 and the plug assembly 5016 are squeezed and discharged through the injection tube 3016.

[0030] In this embodiment, when in use, the temperature measuring component 5011 adopts a bimetallic mechanical sensor. One end of its temperature sensing element is fixed to the housing of the takeover mechanism 5, and the other end is connected to the valve core of the control valve B501 through a connecting rod. The bimetallic strip is made of brass and steel sheets. When the temperature rises, it bends toward the steel sheet, pushing the valve core axially through the connecting rod; when the temperature drops, it bends in the opposite direction, driving the valve core to reset. The connecting rod and the valve core are hinged by a pin shaft, and torsion springs are set at both ends of the pin shaft to ensure that there is no gap in the transmission chain. When the injection pipe 3016 approaches the takeover mechanism 5, the outer conical surface first contacts the plug assembly 5016, and continues to push to make the conical surface fit, while squeezing the spring member 5014. When the set stroke is reached, the valve core of the control valve B501 completes the switch, realizing the synchronous action of "mechanical docking-valve opening". When evacuating, the elastic force of the spring member 5014 pushes the plug to reset, the injection pipe 3016 and the plug are separated, and the channel is automatically closed. The spiral stirring of the horizontal fermentation tank is transmitted with constant torque through a gear reducer. The fluid reaction torque of the circulation mechanism 4 forms a mechanical vibration coupling with the tank body, which can enhance the mixing effect without additional power. It realizes the integrated mechanical linkage of "stirring-heat transfer-temperature control", completely abandons the complexity of traditional electronic control systems, and improves the equipment's anti-interference ability in high humidity and dust environments. At the same time, the detachable design of the purely mechanical structure significantly reduces the difficulty of maintenance, meeting the strict requirements of food processing equipment for hygiene and reliability.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
