Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically a grinding machine for processing oat beverages. Background Technology

[0002] With the popularization of healthy eating concepts, oat drinks, rich in dietary fiber, protein, and various trace elements, have gradually become one of the nutritious beverages favored by consumers. In the processing of oat drinks, grinding is a key step. Its main purpose is to thoroughly grind oats and other grain raw materials and mix them with water to form a uniform slurry, providing a foundation for subsequent blending, homogenization, and sterilization processes.

[0003] Traditional grinding equipment typically employs a single-feed structure and a fixed water injection ratio, which has several shortcomings. For example, in terms of water injection control, existing grinding machines usually use manual or constant-flow water injection methods, which cannot flexibly adjust the water injection volume according to the type of raw materials, moisture content, and process requirements. This results in excessively high or low slurry concentration, affecting the quality of subsequent processing. Furthermore, uneven water injection can easily cause material clumping and pasting, affecting pulping efficiency and finished product quality. In addition, during continuous operation, the motor in traditional grinding equipment generates a large amount of heat over long periods. Poor heat dissipation can not only affect motor performance but also shorten the equipment's lifespan and increase maintenance costs. Therefore, a grinding machine for oat beverage processing is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a grinding machine for processing oat beverages, which has the advantages of precise water flow adjustment and efficient motor heat dissipation, and solves the problems of uneven water injection and poor heat dissipation in existing equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding machine for processing oat beverages, comprising a grinding machine body, wherein a water injection mechanism is provided on the grinding machine body;

[0006] The main body of the grinding mill includes a feeding hopper, a casing, a motor, stirring blades, a moving grinding disc, and a fixed grinding disc. The feeding hopper is installed at the upper end of the casing, the motor is fixedly installed inside the casing, the moving grinding disc and stirring blades are fixedly installed on the output shaft of the motor, and the fixed grinding disc is fixedly installed at the bottom of the feeding hopper. A buffer chamber is provided inside the casing, and a discharge pipe is provided at the bottom of the buffer chamber. The water injection mechanism includes a water storage tank, a submersible pump, a water supply pipe, a water outlet pipe, a diversion valve, and an annular guide pipe. The water storage tank is fixedly installed at the bottom of the casing, the submersible pump is installed inside the water storage tank, the diversion valve is installed between the water supply pipe and the water outlet pipe, the bottom of the water supply pipe is connected to the outlet of the submersible pump, the top of the water outlet pipe is connected to the side wall of the annular guide pipe, and drain outlets are evenly provided at the bottom of the annular guide pipe.

[0007] As a preferred embodiment of the oat beverage processing mill of this utility model, the diversion valve includes a valve body and a valve core. A first return pipe is provided on the side end face of the diversion valve. The valve core is installed in the valve body and rotatably connected thereto. The valve core is provided with a first valve port, a second valve port and a third valve port that cooperate with the water supply pipe, the water outlet pipe and the first return pipe.

[0008] As a preferred embodiment of the oat beverage processing mill of this utility model, the motor end is provided with a heat dissipation jacket, which is made of aluminum alloy.

[0009] As a preferred embodiment of the oat beverage processing mill of this utility model, a spiral flow channel is provided inside the heat dissipation jacket, the bottom of the spiral flow channel is connected to the first return pipe, and the top of the spiral flow channel is provided with a second return pipe connected to the water storage tank.

[0010] As a preferred embodiment of the oat beverage processing mill of this utility model, the top of the water storage tank is provided with a water inlet.

[0011] As a preferred embodiment of the oat beverage processing mill of this utility model, the front end face of the valve core is provided with a vertical plate.

[0012] As a preferred embodiment of the oat beverage processing mill of this utility model, the side end face of the moving grinding disc and the inner end face of the fixed grinding disc are conical structures, and the distance between the fixed grinding disc and the moving grinding disc gradually decreases from top to bottom.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model achieves precise control of water injection flow rate through the diversion valve design of the water injection mechanism. The cooperating annular guide pipe uniformly injects water into the raw materials, improving the grinding quality and avoiding the problems of uneven mixing and slurry caused by single-point water injection. During operation, rotating the valve core can adjust the fit between the second valve port and the water outlet pipe, thereby flexibly controlling the amount of water injected into the grinding zone and directly adjusting the slurry concentration to meet different process requirements. At the same time, excess water flows back to the water storage tank through the first return pipe, avoiding pressure accumulation in the submersible pump due to excessive pipeline resistance. This design solves the problem of fixed water injection ratio and inability to adjust the concentration in real time in traditional grinding machines, and effectively prevents water pump overload damage, significantly improving production adaptability and equipment reliability.

[0015] 2. This utility model adds an aluminum alloy heat dissipation jacket to the motor end. Its internal spiral flow channel, together with the first return pipe of the diversion valve and the second return pipe of the water storage tank, forms a closed-loop water circuit. The low-temperature water returning from the diversion valve enters the spiral flow channel, absorbs heat evenly along the motor surface, and finally flows back to the water storage tank. The spiral structure extends the water flow path and enhances the uniformity of heat dissipation, while the recycling of the return water avoids additional cooling energy consumption. This structure completely solves the problem of shortened motor lifespan due to overheating, and is especially suitable for continuous processing scenarios. Combined with the continuous replenishment of cold water from the water inlet at the top of the water storage tank, the low temperature of the tank is further maintained, forming a sustainable temperature control system.

[0024] The main body 1 of the pulp mill includes a feeding hopper 101, a casing 102, a motor 103, a stirring blade 104, a moving grinding disc 105, and a fixed grinding disc 106. The feeding hopper 101 is installed at the upper end of the casing 102. The motor 103 is fixedly installed inside the casing 102. The moving grinding disc 105 and the stirring blade 104 are fixedly installed on the output shaft of the motor 103. The fixed grinding disc 106 is fixedly installed at the bottom of the feeding hopper 101. A buffer chamber 107 is provided inside the casing 102, and a discharge pipe 108 is provided at the bottom of the buffer chamber 107. The water injection mechanism 2 includes a water storage tank. 201, submersible pump 202, water supply pipe 203, water outlet pipe 205, diversion valve 204, and annular guide pipe 206. The water storage tank 201 is fixedly installed at the bottom of the casing 102. The submersible pump 202 is installed inside the water storage tank 201. The diversion valve 204 is installed between the water supply pipe 203 and the water outlet pipe 205. The bottom of the water supply pipe 203 is connected to the outlet of the submersible pump 202. The top of the water outlet pipe 205 is connected to the side wall of the annular guide pipe 206. The bottom of the annular guide pipe 206 is evenly provided with drain outlets 2061.

[0025] Furthermore, the diversion valve 204 includes a valve housing 2041 and a valve core 2042. A first return pipe 207 is provided on the side end face of the diversion valve 204. The valve core 2042 is installed inside the valve housing 2041 and rotatably connected to it. The valve core 2042 is provided with a first valve port 2043, a second valve port 2044 and a third valve port 2045 that cooperate with the water supply pipe 203, the water outlet pipe 205 and the first return pipe 207.

[0026] The submersible pump 202 pumps water into the diversion valve 204 through the first valve port 2043. By adjusting the overlap between the second valve port 2044 and the outlet pipe 205 through the knob valve core 2042, the water injection rate of the equipment is adjusted and the pulp concentration is adjusted. Pressure is released through the first return pipe 207 to prevent the submersible pump 202 from being damaged due to excessive resistance.

[0027] Furthermore, a heat dissipation jacket 208 is provided at the end of the motor 103, and the heat dissipation jacket 208 is made of aluminum alloy.

[0028] The heat dissipation jacket 208 increases the heat dissipation rate of the motor 103, preventing the motor 103 from overheating and being damaged during long-term processing, thereby extending the service life of the motor 103.

[0029] Furthermore, a spiral flow channel 210 is provided inside the heat dissipation jacket 208. The bottom of the spiral flow channel 210 is connected to the first return pipe 207, and the top of the spiral flow channel 210 is provided with a second return pipe 209 that is connected to the water storage tank 201.

[0030] The cold water returning through the first return pipe 207 is cooled by the spiral flow channel 210 and the heat dissipation jacket 208. Finally, it returns to the water storage tank 201 through the second return pipe 209, thereby further increasing the temperature of the motor 103. The spiral structure also improves the uniformity of heat dissipation, thus extending the service life of the motor 103.

[0031] Furthermore, a water inlet 211 is provided on the top of the water storage tank 201.

[0032] Cold water is continuously supplied through the water inlet 211 to meet the needs of long-term production and to keep the water in the water storage tank 201 at a low temperature for a long time.

[0033] Furthermore, a vertical plate 2046 is provided on the front end face of the valve core 2042.

[0034] The upright plate 2046 facilitates the rotation of the valve core 2042, thereby adjusting the position of the second valve port 2044 and the reflux ratio, thus improving the ease of operation.

[0035] Furthermore, the side end face of the moving grinding disc 105 and the inner end face of the fixed grinding disc 106 are conical structures, and the distance between the fixed grinding disc 106 and the moving grinding disc 105 gradually decreases from top to bottom.

[0036] Grain raw materials are gradually ground into powder particles by the fixed grinding disc 106 and the moving grinding disc 105. After being mixed with water, a slurry is formed. Only after the particle size meets the standard can it pass through the gap between the fixed grinding disc 106 and the moving grinding disc 105.

[0037] When using this pulping machine, cold water is first added through the water inlet 211 at the top of the water storage tank 201 to meet the needs of long-term production and maintain a low water temperature. The submersible pump 202 is then started, and water is pumped into the diversion valve 204 through the water supply pipe 203 and the first valve port 2043. By rotating the vertical plate 2046 on the front end of the valve core 2042, the overlap between the second valve port 2044 and the outlet pipe 205 is adjusted to control the water injection rate and pulping concentration. Simultaneously, pressure is released using the first return pipe 207. Next, raw materials such as oats are added from the feeding hopper 101, and the motor 103 is started. The motor 103 drives the stirring blades 104 to stir the raw materials, while simultaneously... The moving grinding disc 105 rotates and cooperates with the fixed grinding disc 106. The conical structure and gradually decreasing spacing are used to grind the raw material into powder particles. The particles are mixed with water injected into the drain port 2061 of the annular guide pipe 206 to form a slurry. During the grinding process, the heat dissipation jacket 208 at the end of the motor 103 can improve the heat dissipation rate. The cold water returning from the first return pipe 207 is cooled by the spiral flow channel 210 in the heat dissipation jacket 208 and then returned to the water storage tank 201 through the second return pipe 209 to further improve the heat dissipation effect of the motor 103. The ground slurry falls into the buffer chamber 107 in the machine casing 102 and is finally discharged from the bottom discharge pipe 108.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
