Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices for food processing, specifically a mixing device for flour food processing. Background Technology

[0002] A flour mixing device is a specialized piece of equipment used for mixing and stirring flour paste or dough. It is usually driven by a motor and equipped with replaceable stirring paddles (such as hook type, paddle type, or spiral type). It is suitable for making bread, pastries, noodles, and other flour-based foods. Its core function is to fully integrate flour with water, oil, and other ingredients through uniform stirring to form a paste or dough with a fine texture and suitable elasticity.

[0003] Existing flour food processing mixing devices typically do not have the function of cooling the mixed material. When mixing at high speed for a long time, the mixing paddle will generate heat by friction with the mixed material, which can damage the gluten structure, affect yeast activity, or cause oil to melt prematurely, thereby reducing the taste and quality stability of the food. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where, during prolonged high-speed mixing, the mixing paddle generates heat through friction with the material being mixed, which can damage the gluten structure, affect yeast activity, or cause oils to melt prematurely, thereby reducing the taste and quality stability of the food. The invention proposes a mixing device for flour food processing that features simultaneous mixing and cooling of the mixing paddle. Real-time cooling effectively prevents excessive temperature rise of the mixing paddle due to friction or material heating.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a flour-based food processing mixing device, comprising a housing mechanism, an internally fixed mixing mechanism, and an internally fixed cooling mechanism. The mixing mechanism includes a connecting rod, a connecting sleeve fixedly mounted at the bottom of the connecting rod, a mixing paddle movably mounted at the bottom of the connecting rod via the connecting sleeve, and a splined shaft fixedly mounted at the top of the connecting rod. Liquid cooling tanks are formed inside the connecting rod, the mixing paddle, and the splined shaft. The cooling mechanism includes a rotary connector fixedly connected to the top of the splined shaft, a cooling pipe fixedly connected to one side of the rotary connector, a water tank fixedly connected to the bottom of the cooling pipe, a circulating pump fixedly mounted inside the water tank, and a semiconductor cooling chip fixedly mounted on one side of the water tank. The cooling pipe and the liquid cooling tank form a circulation pipeline, and the splined shaft and the connecting rod form a mixing shaft.

[0007] Furthermore, a heat dissipation fin is fixedly installed on the side of the semiconductor cooling chip away from the water tank, and a cooling fan is fixedly installed on one side of the heat dissipation fin.

[0008] Furthermore, the housing mechanism includes a mounting shell, an air inlet on one side of the mounting shell, an air outlet on one side of the mounting shell, and a dustproof net movably installed on one side of both the air inlet and the air outlet.

[0009] Furthermore, a lifting assembly is fixedly installed at the bottom of the housing mechanism, and a base is fixedly installed at the bottom of the lifting assembly.

[0010] Furthermore, a first gear is fixedly installed on the outer wall of the spline shaft, and a second gear is meshed with one side of the first gear. Both the second gear and the first gear are rotatably installed inside the housing mechanism. The spline shaft is slidably installed inside the first gear. A reciprocating screw is fixedly installed on the inner wall of the second gear, and a mounting block is threadedly connected to the outer wall of the reciprocating screw. The mounting block is fixedly installed on the outer wall of the connecting rod.

[0011] Furthermore, the stirring mechanism also includes a motor, a transmission assembly is fixedly installed on the top of the connecting rod, and the output shaft of the motor is fixedly connected to the top of the reciprocating lead screw via a coupling.

[0012] Furthermore, a shock-absorbing pad is fixedly installed at the bottom of the base.

[0013] The present invention provides a flour mixing device for food processing, which has the following advantages: it has the function of simultaneously mixing and cooling the mixing paddle. Real-time cooling can effectively prevent the mixing paddle from overheating due to friction or material heating, thus avoiding dough denaturation, microbial growth, or equipment deformation. Simultaneous cooling and mixing can maintain a stable processing temperature, improve the uniformity of product texture, and is especially suitable for heat-sensitive materials. At the same time, it reduces mechanical wear, extends the life of bearings and seals, and reduces downtime maintenance costs. This design takes into account both production efficiency and food safety, is suitable for high-load continuous production scenarios, and ensures process stability and energy saving.

[0023] See Figures 1-4A flour processing mixing device includes a housing 1, a mixing mechanism 2 and a cooling mechanism 3 fixedly installed inside the housing 1. The mixing mechanism 2 includes a connecting rod 201, a connecting sleeve 202 fixedly installed at the bottom of the connecting rod 201, a mixing paddle 203 movably installed at the bottom of the connecting rod 201 via the connecting sleeve 202, and a splined shaft 205 fixedly installed at the top of the connecting rod 201. Liquid cooling tanks 204 are provided inside the connecting rod 201, the mixing paddle 203, and the splined shaft 205. The cooling mechanism 3 includes a rotary connector 301 fixedly connected to the top of the splined shaft 205, a cooling pipe 302 fixedly connected to one side of the rotary connector 301, a water tank 303 fixedly connected to the bottom of the cooling pipe 302, and a circulating pump 304 fixedly installed inside the water tank 303. A thermoelectric cooler 305 is fixedly installed on one side of the water tank 303. A heat dissipation fin 306 is fixedly installed on the side of the thermoelectric cooler 305 away from the water tank 303. A cooling fan 307 is fixedly installed on one side of the heat dissipation fin 306. The heat dissipation fin 306 and the cooling fan 307 work together to dissipate heat from the heating surface of the thermoelectric cooler 305. The housing mechanism 1 includes a mounting shell 101. An air inlet 102 is opened on one side of the mounting shell 101. An air outlet 103 is opened on one side of the mounting shell 101. A dustproof net 104 is movably installed on one side of both the air inlet 102 and the air outlet 103. Air is introduced through the air inlet 102 and exhausted through the air outlet 103 to work with the cooling fan 307 to dissipate heat from the thermoelectric cooler 305. The cooling pipe 302 and the liquid cooling tank 204 form a circulation pipeline. The spline shaft 205 and the connecting rod 201 form a stirring shaft.

[0024] A first gear 206 is fixedly mounted on the outer wall of the splined shaft 205. A second gear 207 is meshed with one side of the first gear 206. Both the second gear 207 and the first gear 206 are rotatably mounted inside the housing mechanism 1. The splined shaft 205 is slidably mounted inside the first gear 206. A reciprocating screw 208 is fixedly mounted on the inner wall of the second gear 207. A mounting block 209 is threadedly connected to the outer wall of the reciprocating screw 208. The mounting block 209 is fixedly mounted on the outer wall of the connecting rod 201. The engagement of the second gear 207 and the first gear 206 allows the stirring shaft and the reciprocating screw 208 to rotate synchronously. The mounting block 209 enables the reciprocating screw 208 to rotate synchronously. When rotating, the stirring shaft can move up and down. The stirring mechanism 2 also includes a motor 210. A transmission component 211 is fixedly installed on the top of the connecting rod 201. The output shaft of the motor 210 is fixedly connected to the top of the reciprocating screw 208 through a coupling. The motor 210 and the transmission component 211 provide power for the rotation of the reciprocating screw 208. In summary, the stirring paddle 203 can move up and down and back and forth while rotating, forming a three-dimensional motion trajectory when mixing materials. This can enhance the radial shear force to promote uniform mixing of raw materials and eliminate the stirring dead corner through axial displacement. It is especially suitable for high-viscosity dough or processes that require layered mixing, and greatly improves the mixing efficiency.

A shock-absorbing pad 6 is fixedly installed at the bottom of the base 5 to absorb the vibration generated during the operation of the equipment.

[0026] This utility model discloses a flour processing mixing device: it has the function of simultaneously mixing and cooling the mixing paddle 203. Real-time cooling can effectively prevent the mixing paddle 203 from overheating due to friction or material heating, thus avoiding dough denaturation, microbial growth, or equipment deformation. Simultaneous cooling and mixing can maintain a stable processing temperature, improve the uniformity of product texture, and is especially suitable for heat-sensitive materials. At the same time, it reduces mechanical wear, extends the life of bearings and seals, and reduces downtime maintenance costs. This design takes into account both production efficiency and food safety, is suitable for high-load continuous production scenarios, and ensures process stability and energy saving.

[0027] Specifically, the circulating pump 304 circulates the coolant within the cooling pipe 302, the liquid cooling tank 204, and the water tank 303. The semiconductor cooling chip 305 cools the coolant inside the water tank 303, thereby cooling the agitator 203. During this process, the rotating connector 301 allows the agitator shaft to rotate at the bottom of the cooling pipe 302. The connecting sleeve 202 facilitates the replacement of different types of agitators 203.
