Description

Technical Field

[0001] This utility model belongs to the technical field of food processing equipment, specifically relating to a seasoning fermentation tank with temperature control function. Background Technology

[0002] The fermentation process of condiments has strict requirements for temperature stability, raw material uniformity, sealing of the fermentation environment, and smooth discharge. Problems such as temperature fluctuations, raw material clumping, material residues, and sealing failures can directly affect the flavor, quality, and production efficiency of the fermented products. Therefore, the structure of the fermentation tank is crucial to condiment processing.

[0003] Existing seasoning fermentation tanks have several limitations in practical applications: First, temperature control often relies on heating only one tank wall, allowing heat to be conducted from the outside in. Furthermore, the lack of a heat-conducting structure that works in conjunction with stirring results in uneven heating of the materials inside the tank, making it difficult to precisely control the temperature in the core fermentation zone. This leads to inconsistent fermentation levels and poor quality stability. Second, if raw materials clump together during feeding, existing equipment lacks a targeted pre-treatment structure. It either feeds directly, hindering the fermentation of the clumps, or simply uses mechanical crushing, which is ineffective and causes wear on components. It also fails to consider preheating to soften the clumps and reduce crushing difficulty. Third, discharge clumps... The structures are mostly cylindrical or simple funnel-shaped, lacking structures for guiding and cleaning materials at the bottom of the tank. This leads to material accumulation at the bottom of the tank after fermentation, resulting in raw material waste and low discharge efficiency. Fourth, the equipment has insufficient sealing performance. On the one hand, leaks are prone to occur at the connection between rotating parts such as the stirring rod and the heat transfer medium conveying pipeline. On the other hand, the discharge channel lacks a one-way sealing structure, allowing external air and impurities to easily enter the tank, destroying the anaerobic or specific fermentation environment, leading to material contamination or fermentation failure. Fifth, crushing and stirring often use independent drive mechanisms, which not only increases the size of the equipment and energy consumption, but also makes it difficult to achieve coordinated operation of pre-treatment of feed and fermentation stirring in the tank, resulting in poor production process connection and low overall processing efficiency.

[0004] Furthermore, while some existing fermentation tanks have supporting structures, they lack optimization for overall equipment stability. When the stirring and grinding components operate simultaneously, they are prone to shaking, affecting the coordination accuracy of each component and further exacerbating problems such as sealing leaks and uneven material mixing. These shortcomings restrict the large-scale, high-quality production of condiments, thus necessitating a new fermentation tank structure that can solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a seasoning fermentation tank with temperature control function, which aims to solve the core problems of existing seasoning fermentation tanks in the prior art, such as poor temperature control coordination, inefficient handling of raw material clumping, serious material residue, insufficient sealing reliability, and lack of coordination of multi-component drive, resulting in unstable fermentation quality and low production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A seasoning fermentation tank with temperature control function includes:

[0008] A temperature-regulating sleeve is provided, with a feed pipe installed at its top end and a connecting cover fixedly connected to the top end. An inner jacket is installed on the circumferential surface of the temperature-regulating sleeve, and an electric heating device is installed on the circumferential surface of the inner jacket. A stirring rod is rotatably connected inside the temperature-regulating sleeve, and a spiral stirring blade is fixedly connected to the circumferential surface of the stirring rod. A threaded guide groove is provided inside the stirring rod. The stirring rod and the inner jacket are connected by a pipe, and the pipe connection end is rotatably connected to the threaded guide groove through a rotating shaft via a rotary sealing joint. A crushing rod is rotatably installed inside the feed pipe via a bearing seat, and a crushing component is provided inside the feed pipe. The crushing component is used to crush congealed seasonings.

[0009] In a preferred embodiment of this utility model, the crushing assembly includes a crushing wheel and an electric heating device. The electric heating device is fixedly connected to the inner circumferential wall of the feed pipe, and the crushing wheel is fixedly connected to the circumferential surface of the crushing rod. There is a gap between the crushing wheel and the electric heating device. A transmission component is provided on one side of the connecting cover. The transmission component is used to drive the crushing rod and the stirring rod to rotate.

[0010] In a preferred embodiment of this utility model, the transmission component includes a motor, transmission gears, and a toothed belt. There are two transmission gears, which are respectively fixedly connected to the shaft ends of the crushing rod and the stirring rod. The toothed belt is meshed with the circumferential surfaces of the two transmission gears. The motor is fixedly installed on the top of the connecting cover, and the output end of the motor is fixedly installed on the shaft end of the stirring rod.

[0011] As a preferred embodiment of this utility model, a conical collecting hopper is fixedly connected to the bottom end of the temperature regulating sleeve, and a discharge pipe is fixedly installed at the bottom end of the conical collecting hopper.

[0012] As a preferred embodiment of this utility model, a cutting blade is fixedly installed at the shaft end of the stirring rod, and the cutting blade is slidably connected to the inner surface of the conical collecting hopper.

[0013] As a preferred embodiment of this utility model, a one-way valve plate is rotatably installed inside the discharge pipe, and a fixing seat is fixedly installed at the bottom end of the temperature regulating sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this solution, the electric heating device on the surface of the inner jacket enables external heat conduction. At the same time, the heat transfer medium is sent to the threaded guide groove of the stirring rod through the pipeline. With the rotation of the spiral stirring blade, heat is diffused bidirectionally from the outer jacket and the inner stirring rod, completely breaking the limitation of a single heat conduction path. The electric heating device first preheats and softens the agglomerated raw materials to reduce the hardness of the agglomerates. Then, the crushing rod drives the crushing wheel to rotate and impact and crush the agglomerates. A reasonable gap is reserved between the crushing wheel and the electric heating device to avoid interference between the components. At the same time, the synchronous operation of the crushing rod and the stirring rod is achieved by the motor-driven dual transmission gear and toothed belt transmission structure, so that the raw material pretreatment and fermentation stirring in the tank are seamlessly connected.

[0016] 2. In this design, the conical collecting hopper guides the fermented material to the discharge pipe. Combined with the cutting blades at the end of the stirring rod shaft, the cutting blades slide against the inner surface of the collecting hopper when the stirring rod rotates. This not only cuts off any remaining material clumps but also scrapes off any attached material, structurally preventing the accumulation of material at the bottom of the tank. This effectively solves the problem of raw material waste and improves discharge efficiency, allowing fermentation products to be discharged quickly. Attached Figure Description

[0024] Example 1

[0025] Please see Figures 1-4 The present invention provides the following technical solution:

[0026] A seasoning fermentation tank with temperature control function includes:

[0027] A temperature-regulating sleeve 1 is provided, with a feed pipe 101 installed at its top. A connecting cover 103 is fixedly connected to the top of the temperature-regulating sleeve 1. An inner jacket 2 is installed on the circumferential surface of the temperature-regulating sleeve 1, and an electric heating device 201 is installed on the circumferential surface of the inner jacket 2. A stirring rod 3 is rotatably connected inside the temperature-regulating sleeve 1, and a spiral stirring blade 6 is fixedly connected to the circumferential surface of the stirring rod 3. A threaded guide groove is provided inside the stirring rod 3. The stirring rod 3 and the inner jacket 2 are connected by a pipe, and the pipe connection end is rotatably connected to the threaded guide groove through a rotating shaft via a rotary sealing joint. A crushing rod 7 is rotatably installed inside the feed pipe 101 through a bearing seat. A crushing component is provided inside the feed pipe 101, which is used to crush the seasoning that has clumped together.

[0028] In a specific embodiment of this utility model, the temperature-regulating sleeve 1 is the main support structure of the fermentation tank, which accommodates the fermentation of seasonings and is adapted to the installation of components such as the inner jacket 2 and the stirring rod 3, providing an installation foundation and a sealed fermentation space for temperature control and stirring functions.

[0029] The feed pipe 101 is a seasoning raw material feeding channel. The crushing rod 7 is installed through the bearing seat, which provides a pre-operation channel for raw material introduction and agglomeration crushing, ensuring smooth feeding.

[0030] The connecting cover 103 is fixed to the top of the temperature regulating sleeve 1, seals the top of the fermentation tank, supports the installation of components such as the feed pipe 101, and prevents material leakage or external impurities from entering during the fermentation process.

[0031] The inner jacket 2 is set on the circumferential surface of the temperature regulating sleeve 1, carries the electric heating device 201, and transfers heat to the fermentation space.

[0034] The rotary sealing joint connects the pipe end of the stirring rod 3 to the threaded guide groove shaft, ensuring the sealing performance of the stirring rod 3 when it rotates, preventing leakage of the heat transfer medium, and taking into account both rotation and communication functions.

[0035] The crushing rod 7 is rotatably installed in the feed pipe 101 through the bearing seat. It works in conjunction with the crushing component to mechanically crush the condiment raw materials that have clumped together, thereby reducing the particle size of the raw materials.

[0036] The crushing component is located inside the feed pipe 101 and works in conjunction with the crushing rod 7 to break up clumps of seasoning raw materials, preventing large pieces of raw materials from affecting the uniformity of fermentation and improving the fermentation efficiency of raw materials.

[0037] Please refer to the details. Figures 1-4 The crushing assembly includes a crushing wheel 701 and an electric heating device 201. The electric heating device 201 is fixedly connected to the inner circumference of the feed pipe 101, and the crushing wheel 701 is fixedly connected to the circumference of the crushing rod 7.

[0038] In this embodiment: during feeding, the electric heating device 201 in the feed pipe 101 preheats the agglomerated raw material to soften it; the crushing rod 7 drives the crushing wheel 701 to rotate, and crushes the softened agglomerated raw material by impact. The gap avoids interference between components and ensures that the crushed raw material enters the temperature regulating sleeve 1 smoothly.

[0039] Please refer to the details. Figures 1-3 The transmission components include a motor 4, a transmission gear 702, and a toothed belt 703. There are two transmission gears 702, which are fixedly connected to the shaft ends of the crushing rod 7 and the stirring rod 3, respectively. The toothed belt 703 is meshed with the circumferential surfaces of the two transmission gears 702. The motor 4 is fixedly installed on the top of the connecting cover 103, and the output end of the motor 4 is fixedly installed on the shaft end of the stirring rod 3.

[0040] In this embodiment: after the motor 4 starts, the output end drives the stirring rod 3 to rotate. The transmission gear 702 at the shaft end of the stirring rod 3 drives the transmission gear 702 on the crushing rod 7 to rotate synchronously through the toothed belt 703, so that the crushing operation and the stirring operation are carried out in coordination, which not only ensures smooth feeding, but also makes the material heat evenly during fermentation.

[0041] Please refer to the details. Figure 2 The bottom end of the temperature regulating sleeve 1 is fixedly connected to a conical collecting hopper, and the bottom end of the conical collecting hopper is fixedly installed with a discharge pipe 102.

[0042] In this embodiment: Conical collecting hopper: fixed at the bottom of temperature regulating sleeve 1, with a conical structure, it collects the fermented seasonings in temperature regulating sleeve 1 and guides the material to flow to discharge pipe 102 to avoid material residue accumulation.

[0043] The discharge pipe 102 is fixed at the bottom of the conical collecting hopper, serving as a discharge channel for the fermented material. It receives the material guided by the collecting hopper, realizes the centralized discharge of fermentation products, and ensures smooth discharge.

[0044] Please refer to the details. Figures 1-4 A cutting blade 8 is fixedly installed on the shaft end of the stirring rod 3, and the cutting blade 8 is slidably connected to the inner surface of the conical collecting hopper.

[0045] In this embodiment: the cutting blade 8 is fixed to the shaft end of the stirring rod 3, slides against the inner surface of the conical collecting hopper, and rotates with the stirring rod 3 to cut the material clumps attached to the collecting hopper, prevent material residue from accumulating, and assist in smooth discharge.

[0046] Please refer to the details. Figures 1-3 A one-way valve plate 9 is rotatably installed inside the discharge pipe 102, and a fixed seat 5 is fixedly installed at the bottom end of the temperature regulating sleeve 1.

[0047] In this embodiment: the one-way valve plate 9 is rotatably installed inside the discharge pipe 102, allowing only one-way discharge of materials, preventing external air or impurities from entering the temperature regulating sleeve 1, ensuring a sealed fermentation environment, and avoiding material contamination or fermentation failure.

[0048] The fixed base 5 is fixed to the bottom of the temperature regulating sleeve 1, providing stable support for the entire fermenter, distributing the weight of the equipment, preventing the equipment from shaking during fermentation, and ensuring the coordinated operation of all components.

[0049] The working principle and usage process of this utility model are as follows: Before starting the equipment, check the sealing status of the connecting cover 103, the rotary sealing joint, and the flexibility of the one-way valve plate 9 in the discharge pipe 102, and confirm that the fixed seat 5 is installed firmly to avoid shaking during operation; then start the motor 4 at the top of the connecting cover 103, and drive the crushing rod 7 and the stirring rod 3 to rotate synchronously through the meshing transmission of the transmission gear 702 and the toothed belt 703, so that the seasoning raw materials are put into the feed pipe 101. The electric heating device 201 on the inner wall of the feed pipe preheats and softens the lumpy raw materials. After the crushing rod 7 drives the crushing wheel 701 to efficiently crush the raw materials, the raw materials enter the temperature regulating sleeve 1; during the fermentation process, the inner jacket 2 surface The electric heating device 201 conducts heat through a jacket, while the heat transfer medium is sent through a pipe into the threaded guide groove of the stirring rod 3. This, combined with the rotation of the spiral stirring blade 6, achieves dual temperature control and uniform stirring, precisely controlling the fermentation temperature. After fermentation, the material is guided by the conical collecting hopper to the discharge pipe 102. The cutting blade 8 at the shaft end of the stirring rod 3 rotates against the inner surface of the collecting hopper, scraping off residues and cutting clumps. The gravity of the material pushes the one-way valve plate 9 to open, achieving smooth discharge. After discharge, the valve plate automatically resets to ensure sealing. Finally, the motor and electric heating device are turned off. After the equipment cools down, the residual raw material debris in the feed pipe is cleaned, and the wear of the parts is checked to ensure subsequent use.
