Description

Technical Field

[0001] This invention relates to the field of bio-based material production technology, specifically to a high-efficiency, high-temperature sterilization and rapid cooling bio-based material mixing device. Background Technology

[0002] Bio-based substrates refer to artificially synthesized substrates that include sawdust, bran, cottonseed hulls, straw, leaves, and other main materials, along with additives such as nutrient solutions and disinfectants in a certain proportion. They can be used for planting or breeding under conditions of their form, ratio, density, moisture, and temperature.

[0003] The traditional production process of existing bio-based materials is as follows: the main and auxiliary materials, additives and water are mixed in proportion at room temperature, bagged or left to stand in a sterile room, and then directly sterilized by steam or high-temperature hot air filtration, naturally cooled, and then used for planting or breeding; bio-based materials are packaged in plastic bags to form material sticks for high-temperature sterilization.

[0004] A heating, cooling, and stirring device, with announcement number CN208049735U, is characterized by comprising a stirring shaft and a stirring coil. The stirring shaft is linear, and its upper end has a stirring handle connector for connecting to a rotary motor. The stirring shaft is fixed to the stirring coil and is used to drive the stirring coil to rotate and stir the material. The stirring shaft has bidirectional fluid passages, communicating with both ends of the stirring coil. This device relies solely on a single linear stirring shaft and coil to complete stirring and media heat exchange, resulting in a limited stirring method, poor sterilization penetration, and low cooling efficiency.

[0005] A mixer with steam heating and cooling functions, disclosed in announcement number CN222034632U, includes a machine body and a mixing chamber installed within the machine body. The mixer also includes a steam system and a cooling system, with the steam system connected to the mixing chamber. The mixing chamber is used to mix powdered materials with water to form raw feed. The steam system is used to introduce steam into the mixing chamber to cook the raw feed. The cooling system is used to cool the mixing chamber and the cooked feed. This mixer only has a single-chamber steam cooking and simple cooling function, relying solely on conventional mixing within the mixing chamber. Its function is limited, the material mixing uniformity is insufficient, and sterilization and cooling both depend on a single external heat and cold source.

[0006] The problems with the above methods are as follows: during the sterilization process after bagging, because the packaging bags are made of plastic, the sterilization steam temperature is low and the time is long, making it difficult to penetrate into the material bar; if the bulk material is left to stand in the sterile room and the high-temperature hot air is filtered and then blown directly onto the surface of the base material, it is also difficult to blow through, and it will cause a large amount of dehydration of the base material; and the cooling process takes even longer due to natural cooling, which in turn prolongs the subsequent planting and breeding, resulting in low efficiency, simple mixing structure, and single heat exchange method. Summary of the Invention

[0007] The purpose of this invention is to provide a highly efficient, high-temperature sterilization and rapid cooling bio-based material mixing device to solve the above-mentioned problems and overcome the shortcomings of the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a high-efficiency high-temperature sterilization and rapid cooling bio-based material mixing device, comprising a horizontal silo, a mixing assembly, an external heating assembly, a rotary drive assembly, a rotary support and locking assembly, a gas-liquid flushing pipeline assembly, an internal heating assembly, and a chiller. The horizontal silo has an inlet and an outlet at its top and bottom, respectively. A sealed channel is concentrically arranged on the outside of the horizontal silo. A cooling water outlet pipe, a hot air inlet pipe, a cooling water inlet pipe and a hot air outlet pipe are connected to the sealed channel. The chiller is located at the position of the cooling water inlet pipe. The stirring assembly includes a stirring shaft and spiral blades mounted on the stirring shaft. The stirring shaft rotatably passes through both ends of a horizontal silo. The stirring shaft has a gas-liquid cavity inside, and the shaft wall of the stirring shaft has several gas-liquid spray holes for communicating with the gas-liquid cavity and the interior of the horizontal silo. Both ends of the stirring shaft are provided with gas-liquid flushing pipe assemblies for communicating with the gas-liquid cavity. The rotary drive assembly is located at the end of the stirring shaft and can drive the stirring shaft to rotate. The horizontal silo is provided with a toothed structure that can fix it to the stirring shaft. When the toothed structure fixes the horizontal silo to the stirring shaft, the rotary drive assembly can drive the horizontal silo and the stirring shaft to rotate synchronously under the support of the rotary support locking assembly. The external heating component, in conjunction with a sealed channel, hot air inlet pipe, and hot air outlet pipe, heats the base material from the outer wall of the horizontal silo inward. The internal heating component, in conjunction with a stirring shaft, heats the base material from the inside of the horizontal silo to the outer wall. The chiller, in conjunction with a sealed channel, cooling water outlet pipe, and cooling water inlet pipe, cools the base material inside the horizontal silo.

[0009] The present invention proposes some specific embodiments, wherein the stirring shaft has two coaxially designed stirring shafts, the ends of the two stirring shafts are rotatably connected to each other through a connecting shaft, the spiral blades on the two stirring shafts are arranged to rotate in opposite directions, and the rotation drive assembly has two sets corresponding to the two stirring shafts and can realize independent rotation of the stirring shafts and the spiral blades on them.

[0010] This invention proposes some specific embodiments. The rotary drive assembly includes a motor. The output shaft of the motor is connected to a first toothed pulley via a reducer. A second toothed pulley, corresponding vertically to the first toothed pulley, is fixed on the stirring shaft. The first toothed pulley and the second toothed pulley are connected by synchronous toothed belt meshing.

[0011] This invention proposes some specific embodiments. The toothed structure includes an inner positioning toothed ring fixedly sleeved on the stirring shaft. An outer positioning toothed ring is axially movable on the outer side of the inner positioning toothed ring. Support ears are fixedly provided on both sides of the outer positioning toothed ring. A guide rod is slidably connected through each support ear. One end of the two guide rods is fixedly connected to a horizontal hopper. An electric push rod is fixedly provided on the horizontal hopper. The push rod head of the electric push rod is fixedly connected to the support ear. When the push rod of the electric push rod reaches its maximum stroke, the outer positioning toothed ring and the inner positioning toothed ring separate from each other. When the push rod of the electric push rod reaches its minimum stroke, the outer positioning toothed ring and the inner positioning toothed ring mesh with each other.

[0012] This invention proposes some specific embodiments. The rotary support locking assembly has two or more sets and is located on the lower side of the horizontal silo. The rotary support locking assembly includes a support frame, on which two or more support wheels are rotatably mounted. The outer side of the horizontal silo is provided with a guide wheel ring. The outer side of the support wheel is provided with an annular groove that cooperates with and limits the guide wheel ring. The bottom side of the guide wheel ring is provided with a positioning insertion hole. The support frame is provided with a cylinder. The push rod head of the cylinder faces upward and is fixedly connected to a positioning pin that cooperates with the positioning insertion hole.

[0013] This invention proposes some specific embodiments. The gas-liquid flushing pipeline assembly includes a sealing rotating collar that is rotatably and sealed on the outside of the stirring shaft. The stirring shaft has a communication channel that communicates with the gas-liquid cavity. The side wall of the stirring shaft located inside the sealing rotating collar has several perforations that communicate with the communication channel. One end of the gas-liquid conduit that can communicate with the communication channel through the perforations is connected to the sealing rotating collar. The other end of the gas-liquid conduit is connected to a gas guide pipe and a liquid guide pipe, respectively. An electromagnetic three-way valve is provided between the gas-liquid conduit, the gas guide pipe, and the liquid guide pipe.

[0014] The present invention proposes some specific embodiments, wherein the internal heating assembly includes a temperature controller disposed at the end of the stirring shaft and an electric heating rod disposed in the gas-liquid cavity, wherein the temperature controller and the electric heating rod are electrically connected to each other; The external heating component includes a variable frequency fan installed at the hot air inlet pipe, and a heating element is provided between the variable frequency fan and the hot air inlet pipe.

[0015] The present invention proposes some specific embodiments, wherein the side wall of the horizontal silo is provided with a temperature sensor for detecting the temperature in the closed channel, a pressure sensor for detecting the pressure in the closed channel, a safety valve for providing safety protection in the closed channel, and a camera for observing the closed channel.

[0016] The present invention proposes some specific embodiments in which a drain pipe is provided on one side of the bottom of the horizontal silo, and a solenoid valve is provided on the drain pipe.

[0017] The present invention proposes some specific embodiments in which a spiral guide rib is provided in the sealed channel.

[0018] The beneficial effects are: 1. The system uses a horizontal silo as the main sealed processing unit, with hot air and cooling water circulating through an outer sealed channel. A rotary drive assembly drives the mixing assembly to agitate the materials. Simultaneously, a toothed structure and a rotary support locking assembly allow the mixing shaft to rotate independently or synchronously with the horizontal silo. This system features a dual sterilization structure with both external and internal heating components, along with a chiller for rapid cooling after sterilization. Finally, an air-liquid flushing pipeline assembly ensures ventilation, prevents blockages, and provides internal self-cleaning. The system integrates mixing, sterilization, cooling, rotary positioning, and self-cleaning functions, effectively solving the problems of incomplete sterilization, slow cooling, easy material dehydration, and low operating efficiency associated with traditional equipment.

[0019] 2. This invention uses a horizontal silo as a closed working chamber, surrounded by a closed channel and equipped with a spiral guide rib, which can guide the hot air and cooling water in a spiral manner, extending the heat exchange path of the medium. With the help of temperature sensors, pressure sensors, safety valves, and cameras, it can realize real-time monitoring of temperature and pressure, overpressure safety relief, and real-time monitoring of working conditions. Furthermore, the sterilization effect can be sampled at any time through the detection pipeline, eliminating the drawbacks of traditional judgment based on experience, and greatly improving the controllability of sterilization quality.

[0020] 3. This invention uses a dual stirring shaft with reverse-arranged spiral blades, and achieves flexible linkage between the two shafts by connecting the rotating shaft. It is equipped with two sets of independent rotating drive components, which consist of a motor, a reducer, a first toothed pulley, a synchronous toothed belt, and a second toothed pulley to form a synchronous transmission mechanism. This enables multiple rotation combination modes of the dual shafts to perform bidirectional convection tumbling and stirring of the bio-based material.

[0021] 4. The mixing shaft is equipped with a gas-liquid cavity and gas-liquid spray holes. This can be used in conjunction with the temperature controller and electric heating rod of the internal heating component to conduct heat source inside the shaft, and can also be connected to the gas-liquid flushing pipe assembly to achieve air jet anti-clogging. This results in good mixing uniformity and prevents material accumulation and clogging of the holes.

[0022] 5. This invention uses a chiller in conjunction with a cooling water inlet pipe, a cooling water outlet pipe and a sealed channel to form a closed cooling circulation loop. After sterilization, it can quickly circulate and cool the horizontal silo and the internal base material. At the same time, it is combined with a stirring shaft to continuously turn the material and exchange heat, which changes the defect of the traditional natural cooling cycle being too long. The cooling efficiency is significantly improved, and the base material is effectively prevented from deteriorating and dehydrating due to prolonged static storage.

[0023] 6. The present invention is equipped with a toothed structure and a rotary support locking component that work together. The toothed structure can switch between synchronous rotation of the horizontal hopper and the stirring shaft or rotation of the horizontal hopper alone. Under the support of the rotary support locking component, the horizontal hopper can reciprocate at a certain angle to break up the accumulated materials and reduce the running resistance of the spiral blades. At the same time, it can meet the needs of multiple working conditions such as static sterilization and fixed-point discharge, making the equipment more adaptable.

[0024] 7. The gas-liquid flushing pipeline assembly of the present invention can flexibly switch between air and liquid modes. It can either introduce high-pressure gas to spray air from the gas-liquid nozzle to prevent blockage, or introduce cleaning liquid to spray and clean the chamber and shaft interior in all directions. The cleaning waste liquid can be automatically discharged through the drain pipe and solenoid valve, without the need for manual disassembly and cleaning. It has a high degree of automation and is convenient and hygienic. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] Example 1: See Figures 1-12 As shown, the present invention provides a high-efficiency high-temperature sterilization and rapid cooling bio-based material mixing device, which mainly includes a horizontal silo 1, a mixing component, an external heating component 3, a rotary drive component 4, a rotary support and locking component 5, a gas-liquid flushing pipeline component 6, an internal heating component 7, and a chiller 8.

[0030] The horizontal silo 1 is equipped with a base 10 below it. The base 10 serves as the support base for the entire machine and is mainly used to securely install the rotary drive assembly 4 and the rotary support locking assembly 5. At the same time, a detection pipe 16 is installed through the upper side wall of the horizontal silo 1. The detection pipe 16 can be used to pick up and put in detection rods or test strips, which facilitates the staff to sample and test the single high-temperature sterilization effect of the biological substrate. In order to reduce heat loss in the silo and improve temperature control stability, the outer wall of the horizontal silo 1 is also covered with a heat insulation layer 103, which plays a role in heat insulation, heat preservation, energy saving and consumption reduction.

[0031] Furthermore, the horizontal silo 1 has an inlet 101 at the top center and an outlet 102 at the bottom, which are used for feeding the bio-based material and discharging it after processing, respectively. A closed channel 105 is arranged concentrically around the outside of the horizontal silo 1. This channel is a heat exchange medium circulation cavity. Cooling water outlet pipe 104, hot air inlet pipe 107, cooling water inlet pipe 108 and hot air outlet pipe 109 are respectively connected to the closed channel 105 on the outer wall of the horizontal silo 1 to realize the circulation of hot air and cooling water. The chiller 8 is installed on the cooling water inlet pipe 108. Its main function is to prepare low-temperature cooling water to provide a cold source for the rapid cooling of the bio-based material after sterilization.

[0032] Meanwhile, the device is equipped with a stirring assembly, which mainly consists of a stirring shaft 2 and a spiral blade 17 fixed on the shaft of the stirring shaft 2. The stirring shaft 2 is rotatably mounted on the central axis of the horizontal silo 1. With the help of the spiral blade 17, it can achieve rotational stirring. The interior of the stirring shaft 2 is hollow, forming a gas-liquid cavity 201, which serves as an internal flow channel for gas and liquid media. Furthermore, several gas-liquid spray holes 203 are evenly opened on the shaft wall of the stirring shaft 2 to connect the gas-liquid cavity 201 with the internal cavity of the horizontal silo 1, thereby realizing the functions of media injection, anti-clogging, and auxiliary heat exchange.

[0033] Gas-liquid flushing pipe assemblies 6 are installed at both ends of the stirring shaft 2 to deliver gas or cleaning liquid to the gas-liquid cavity 201. The rotary drive assembly 4 is installed on the outer side of the end of the stirring shaft 2 and is the drive mechanism that provides power output for the rotation of the stirring shaft 2. In addition, a toothed structure 9 is added to the outer side of the horizontal hopper 1 to realize the rigid locking and separation switching between the horizontal hopper 1 and the stirring shaft 2. When the toothed structure 9 is engaged and locked, the rotary drive assembly 4 can drive the horizontal hopper 1 and the stirring shaft 2 as a whole to rotate synchronously under the support and limiting action of the rotary support locking assembly 5 below.

[0034] In addition, the external heating component 3 can work with the sealed channel 105, the hot air inlet pipe 107 and the hot air outlet pipe 109 to form a hot air circulation loop, transferring heat from the outer wall of the horizontal silo 1 inward to achieve external heating and sterilization of the bio-based material; the internal heating component 7 works with the stirring shaft 2 to form an internal heat source conduction path, radiating heat from the inside of the horizontal silo 1 to the outside, achieving dual heating and sterilization inside and outside; the chiller 8 works with the sealed channel 105, the cooling water outlet pipe 104 and the cooling water inlet pipe 108 to form a cooling circulation loop, quickly removing heat from the horizontal silo 1 and the bio-based material, completing the rapid cooling operation after sterilization.

[0035] Example 2: Based on the first example, refer to the appendix of the instruction manual. Figure 2 , Figure 4 and Figure 5 As shown, this embodiment further optimizes the design of the stirring assembly.

[0036] Two mixing shafts 2 are provided. The two mixing shafts 2 adopt a dual-shaft coaxial layout design. The adjacent ends of the two mixing shafts 2 located in the horizontal silo 1 are connected by a connecting shaft 202 to achieve rotational connection, ensuring that the two shafts can rotate relatively flexibly. At the same time, the spiral blades 17 installed on the two mixing shafts 2 are arranged in opposite directions, which can form bidirectional tumbling and convection mixing of the bio-based material inside the horizontal silo 1, greatly improving the mixing uniformity.

[0037] Correspondingly, two sets of rotary drive components 4 are synchronously provided, each independently assembled with one of the two stirring shafts 2, and can drive each stirring shaft 2 and the corresponding spiral blade 17 to rotate autonomously. The dual shafts can realize multiple combination modes of rotation in the same direction and in opposite directions, resulting in four material conveying and stirring methods, which can adapt to the stirring and processing needs of bio-based materials with different viscosities and properties, and have stronger versatility.

[0038] Example 3: Based on the above examples, please refer to the appendix to the instruction manual. Figure 1 and Figure 3 As shown, this embodiment specifically defines the detailed structure and transmission principle of the rotary drive component 4.

[0039] Each set of rotary drive components 4 includes a drive motor 401, a reducer 402, a first toothed pulley 403, a synchronous toothed belt 404, and a second toothed pulley 405. The drive motor 401 is the power source, and its output shaft is connected to the input end of the reducer 402. The reducer 402 plays the role of speed reduction, torque increase, and speed stabilization. The first toothed pulley 403 is fixedly mounted on the output shaft of the reducer 402. In practical applications, an absolute rotary encoder can also be set on the output shaft of the reducer 402 to achieve the rotation angle positioning of the stirring shaft 2.

[0040] The second toothed pulley 405 is fixedly mounted on the outer side of the end of the stirring shaft 2 and is positioned vertically opposite to the first toothed pulley 403. The first toothed pulley 403 and the second toothed pulley 405 are connected by a synchronous toothed belt 404 for transmission. Precise synchronous transmission is achieved by relying on the toothed belt meshing. The transmission is smooth and there is no slippage. It can stably control the uniform rotation of the stirring shaft 2 and ensure the stability of the stirring operation.

[0041] Example 4: Based on the above examples, please refer to the appendix to the instruction manual. Figure 1 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown in the figure, this embodiment details the composition and switching working principle of the tooth structure 9.

[0042] The toothed structure 9 mainly consists of an inner positioning toothed ring 902, an outer positioning toothed ring 901, a support lug 903, a guide rod 904, and an electric push rod 905. The inner positioning toothed ring 902 is fixedly and sealed on the outer wall of the stirring shaft 2, maintaining synchronous rotation with the stirring shaft 2. The outer positioning toothed ring 901 is axially slidably sleeved on the outside of the inner positioning toothed ring 902, and can be moved axially to achieve engagement and disengagement.

[0043] Symmetrical lugs 903 are welded to the left and right sides of the outer positioning gear ring 901. Each lug 903 is vertically slidably fitted with a guide rod 904. One end of each guide rod 904 is fixedly connected to the side wall of the horizontal silo 1 to limit the translation trajectory of the outer positioning gear ring 901 and prevent it from deviating or jamming. An electric push rod 905 is fixedly installed on the outer wall of the horizontal silo 1. The telescopic push rod end of the electric push rod 905 is fixedly connected to the lug 903 and serves as the power drive for the translation of the outer positioning gear ring 901.

[0044] In actual operation, when the electric push rod 905 extends to its maximum stroke, it can pull the outer positioning gear ring 901 to move axially, so that it is completely separated from the inner positioning gear ring 902. At this time, the horizontal hopper 1 remains stationary, and only the stirring shaft 2 rotates independently for stirring. When the electric push rod 905 retracts to its minimum stroke, it can push the outer positioning gear ring 901 to engage and lock with the inner positioning gear ring 902, so that the horizontal hopper 1 and the stirring shaft 2 are connected as one unit, thereby realizing synchronous rotation operation.

[0045] Example 5: Based on the above examples, please refer to the appendix to the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown in the figure, this embodiment details the structure and function of the rotary support locking assembly 5.

[0046] At least two sets of rotary support locking components 5 are provided, symmetrically arranged on the left and right sides of the bottom of the horizontal silo 1 along its axial direction, mainly serving the functions of load-bearing, rotational guidance, and circumferential locking; each set of rotary support locking components 5 consists of a guide wheel ring 501, a support wheel 502, a support frame 503, an annular groove 504, a cylinder 505, a positioning pin 506, and a positioning hole 507.

[0047] The support frame 503 is fixedly installed on the base 10 by bolts or welding, serving as an overall support base. At least two support wheels 502 are rotatably mounted on the upper end of the support frame 503 to support the horizontal silo 1. A guide wheel ring 501 is fixedly fitted on the outside of the horizontal silo 1. The cross-sectional shape of the guide wheel ring 501 is an isosceles trapezoid. The outer circular surface of the support wheel 502 has an annular groove 504, which engages with the outer ring of the guide wheel ring 501 to limit and lock. This not only stably supports the weight of the silo but also guides and limits the rotation of the horizontal silo 1, preventing rotational deviation.

[0048] Meanwhile, positioning holes 507 are evenly opened on the bottom side of the guide wheel ring 501. A cylinder 505 is vertically installed on the support frame 503. The cylinder 505's telescopic push rod is fixedly connected to the positioning pin 506 with its extension rod facing upward. When the horizontal hopper 1 needs to be locked at rest, the cylinder 505 push rod extends, pushing the positioning pin 506 into the positioning hole 507 to achieve circumferential fixation of the hopper. When the hopper needs to rotate synchronously, the cylinder 505 retracts, causing the positioning pin 506 to disengage from the positioning hole 507, releasing the lock so that it can rotate freely. In practical applications, a position sensor can also be set on the support frame 503 to detect the position of the horizontal hopper 1, which is used to facilitate the detection and positioning of the deflection angle of the horizontal hopper 1.

[0049] Example 6: Based on the above examples, see the appendix to the instruction manual. Figure 4 , Figure 7 and Figure 12 As shown in the figure, this embodiment provides a detailed structural description of the gas-liquid flushing pipeline assembly 6.

[0050] The gas-liquid flushing pipeline assembly 6 includes a sealing rotating collar 601, a gas-liquid conduit 602, an electromagnetic three-way valve 603, a gas guide pipe 604, and a liquid guide pipe 605, and works in conjunction with the connecting channel 204 and the perforation 205 inside the stirring shaft 2.

[0051] The sealing rotating collar 601 is fitted on the outer side of the end of the stirring shaft 2, which neither hinders the rotation of the stirring shaft nor prevents leakage of the pipeline. In practical applications, the sealing rotating collar 601 remains stationary, and the stirring shaft 2 rotates in a sealed manner within the sealing rotating collar 601. This can be achieved by connecting and fixing the sealing rotating collar 601 to an external component such as the base 10. The stirring shaft 2 has a connecting channel 204 inside, which communicates with the gas-liquid cavity 201. Several perforations 205 are provided on the side wall of the stirring shaft 2 within the area covered by the sealing rotating collar 601, which are used to connect the gas-liquid conduit 602 and the connecting channel 204 during the rotation or rest of the stirring shaft 2.

[0052] The outer side of the sealing rotating collar 601 is connected to and fixed one end of the gas-liquid conduit 602. The other end of the gas-liquid conduit 602 is connected to the gas pipe 604 and the liquid pipe 605 respectively through the electromagnetic three-way valve 603. By switching the on and off of the electromagnetic three-way valve 603, high-pressure gas can be introduced into the gas pipe 604 and sprayed out from the gas-liquid spray hole 203 through the pipeline and orifice to prevent the base material from clogging the spray hole and assist sterilization. Alternatively, cleaning liquid can be introduced into the liquid pipe 605 to realize automatic spraying and rinsing in the silo and simplify manual cleaning operations. In the above process, in order to adapt to the deflection and rotation of the horizontal silo 1, the connecting pipes of the gas pipe 604 and the liquid pipe 605 to the external gas supply pipe and liquid supply pipe can be flexible pipes.

[0053] Example 7: Based on the above examples, refer to the appendix to the instruction manual. Figure 1 , Figure 4 and Figure 5 As shown, this embodiment defines the specific composition and heating principle of the internal heating component 7 and the external heating component 3.

[0054] The internal heating component 7 consists of a temperature controller 701 and an electric heating rod 702. The temperature controller 701 is installed on the outer side of the end of the stirring shaft 2, and the electric heating rod 702 is installed inside the gas-liquid cavity 201 of the stirring shaft 2. The temperature controller 701 is electrically connected to the electric heating rod 702 and can adjust the heating temperature. The heating rod 702 heats up the entire stirring shaft 2, and then conducts heat to the base material in the chamber through the shaft wall and the gas-liquid spray hole 203 to achieve internal heating and sterilization.

[0055] The external heating component 3 consists of a variable frequency fan 301 and a heating element 302. The variable frequency fan 301 is installed at the front end of the hot air inlet pipe 107, and the heating element 302 is installed between the variable frequency fan 301 and the hot air inlet pipe 107. The airflow delivered by the variable frequency fan 301 is heated into high temperature hot air by the heating element 302 and sent into the closed channel 105 for circulation. It radiates heat from the outer wall of the silo to the inside, forming a double heating effect with the internal heating component, resulting in more uniform sterilization and higher efficiency.

[0056] Example 8: Based on the above examples, this example adds detection, safety and sewage discharge auxiliary components to improve the overall intelligence and safety protection performance of the machine.

[0057] The side wall of the horizontal silo 1 is equipped with a temperature sensor 12, a pressure sensor 13, a safety valve 14, and a monitoring camera 15. The temperature sensor 12 detects the temperature of the medium inside the sealed channel 105 in real time, and the pressure sensor 13 monitors the pressure inside the silo and the sealed channel 105 in real time, providing data support for temperature and pressure control. The safety valve 14 serves as an overpressure safety protection component, automatically releasing pressure when the pressure inside the sealed channel 105 exceeds the standard, preventing equipment damage due to pressure. The monitoring camera 15 captures the working conditions inside the silo in real time, facilitating remote and intuitive observation of the mixing and sterilization status.

[0058] Meanwhile, a drain pipe 11 is opened on the bottom side of the horizontal silo 1 to discharge wastewater and waste liquid from equipment cleaning. A solenoid valve 1101 is installed on the drain pipe 11, which can be electrically controlled to automatically open and close the drain, eliminating the need for manual operation and achieving a high degree of automation. In addition, a spiral guide rib 106 is fixedly installed inside the sealed channel 105, which can guide hot air and cooling water to circulate in an orderly manner along the spiral path, extending the flow path of the heat exchange medium and improving the uniformity of heating and cooling and the heat exchange efficiency.

[0059] Working principle of the invention: During operation, the bio-based material is fed into the horizontal silo 1 through the inlet 101 and discharged through the outlet 102. In practical applications, silo covers are also provided at the inlet 101 and outlet 102 respectively. After closing the silo covers at the inlet 101 and outlet 102, a sealed cavity is formed inside the horizontal silo 1. The motor 401 of the rotary drive assembly 4 is started, and after being reduced in speed and torque by the reducer 402, it drives the first toothed pulley 403 to rotate. The first toothed pulley 403 drives the second toothed pulley 40 through the meshing of the synchronous toothed belt 404. 5. This drives the stirring shaft 2 and the spiral blades 17 fixed on the stirring shaft 2 to rotate. The two sets of coaxially arranged stirring shafts 2 are connected by the rotating shaft 202 and rotate in opposite directions. This allows for bidirectional tumbling and uniform mixing of the bio-based material inside the horizontal silo 1. The two stirring shafts 2 can be driven independently by the corresponding rotating drive components 4. The rotation directions of the two stirring shafts 2 can be in the same direction or in opposite directions. When the two stirring shafts are combined with the spiral blades 17, there are four ways to transfer the bio-based material in the horizontal silo 1. The outer wall of the horizontal silo 1 is covered with an insulation layer 103, and a closed channel 105 is arranged concentrically around the outside. Spiral guide ribs 106 are arranged inside the closed channel 105 to guide the orderly circulation of hot air and cooling medium. Under heating and sterilization conditions, the variable frequency fan 301 of the external heating component 3 delivers air that is heated by the heating element 302 and then sent into the sealed channel 105 through the hot air inlet pipe 107. After circulating and exchanging heat along the outer wall of the horizontal silo 1 along the spiral guide rib 106, the air returns from the hot air outlet pipe 109, achieving external surrounding hot air heating and sterilization. At the same time, the temperature controller 701 of the internal heating component 7 controls the electric heating rod 702 inside the gas-liquid cavity 201 of the stirring shaft 2 to work, thereby heating the stirring shaft 2 internally. The heat is transferred through the stirring... The mixing shaft 2 and the gas-liquid spray hole 203 conduct heat to the base material, forming an internal electric heating sterilization. The combination of internal and external heating greatly improves the sterilization efficiency and uniformity. During the process, the temperature sensor 12 detects the temperature in the sealed channel 105 in real time, the pressure sensor 13 detects the pressure in the cavity in real time, the safety valve 14 plays a role in overpressure safety relief protection, the camera 15 monitors the working conditions in the silo in real time, and the detection pipe 16 set on the side wall of the horizontal silo 1 can insert a detection rod or test paper for convenient sampling and inspection of the sterilization effect.

[0060] After sterilization, the system switches to cooling mode. The chiller 8 introduces low-temperature cooling water into the closed channel 105 through the cooling water inlet pipe 108. The water circulates under the guidance of the spiral guide rib 106 and finally flows back to the chiller 8 from the cooling water outlet pipe 104 to form a closed loop, quickly removing the heat from the horizontal silo 1 and the base material inside. The stirring shaft 2 continuously stirs at low speed, causing the base material to constantly turn over and exchange heat, achieving rapid cooling without dead angles and solving the problems of long time consumption and severe dehydration of the base material in traditional natural cooling.

[0061] The toothed structure 9, through the extension and retraction of the electric push rod 905, drives the support lug 903 to slide along the guide rod 904, controlling the engagement or disengagement of the outer positioning tooth ring 901 with the inner positioning tooth ring 902 fixed on the stirring shaft 2. When engaged, the horizontal silo 1 is rigidly connected to the stirring shaft 2. The rotary support locking assembly 5, through the support wheel 502 on the support frame 503 and the annular groove 504, supports the guide wheel ring 501 on the outside of the horizontal silo 1, realizing the rotatable support of the horizontal silo 1. At this time, the rotary drive assembly 4 can synchronously drive the stirring shaft 2 and the horizontal silo 1 to rotate as a whole. During this process, the horizontal silo 1 reciprocates within 0-90°, realizing the shaking of the material inside. The stirring action ensures uniform material distribution within the hopper. When locking is required, the cylinder 505 pushes the positioning pin 506 into the positioning hole 507 of the guide wheel ring 501, thus fixing the horizontal hopper 1 circumferentially. Then, the electric push rod 905 drives the outer positioning tooth ring 901 to separate from the inner positioning tooth ring 902, allowing the rotary drive assembly 4 to drive the stirring shaft 2 independently, keeping the horizontal hopper 1 stationary. The application scenario of the above function is that under the drive of the spiral blades 17, the material is prone to concentration, which will cause great resistance to the operation of the spiral blades 17. The reciprocating deflection of the horizontal hopper 1 can alleviate this problem. The equipment's self-cleaning and internal heating hot air circulation anti-clogging mechanism is achieved by the gas-liquid flushing pipe assembly 6. A sealing rotating collar 601 is rotatably fitted onto the outer side of the end of the stirring shaft 2. The gas-liquid conduit 602 is switched between the gas conduit 604 and the liquid conduit 605 via an electromagnetic three-way valve 603. The medium enters the gas-liquid cavity 201 of the stirring shaft 2 through the perforation 205 and the connecting channel 204, and is then sprayed into the chamber through the gas-liquid spray nozzle 203, completing internal ventilation and spray flushing operations. During cleaning, the liquid conduit 605 is connected to the gas-liquid conduit 602 for air jet anti-clogging or internal heating introduction. When hot air is used, the air guide pipe 604 and the gas-liquid conduit 602 can be connected. The above application scenario is that when the bio-based material is stirred and mixed, the bio-based material is prone to clogging the gas-liquid nozzle 203. The positive pressure air jet formed by the gas-liquid nozzle 203 can effectively prevent clogging and improve the high-temperature sterilization effect. The wastewater generated during cleaning is finally discharged through the bottom drain pipe 11 of the horizontal silo 1 and the solenoid valve 1101, realizing the self-cleaning of the equipment. The whole process is automated and linked without manual intervention, which greatly shortens the sterilization and cooling cycle of the bio-based material.
