Description

Technical Field

[0001] This utility model relates to the field of mixing technology, and in particular to a stirring device that enables the recycling of food raw materials. Background Technology

[0002] In the food processing industry, the mixing device is the core equipment for mixing and homogenizing raw materials. The design of its discharge section directly affects production efficiency and product quality. The discharge pipes of traditional mixing devices mostly adopt a straight cylindrical structure, which is simple to design and easy to manufacture.

[0003] Currently, the discharge pipes of commonly used mixing devices on the market are usually straight pipes with a fixed diameter, installed vertically or nearly vertically. These straight pipes can generally handle low-viscosity food raw materials with good flowability, such as watery beverages and thin sauces. However, when dealing with high-viscosity raw materials or materials containing particles, such as red bean paste or peanut butter, the high-viscosity materials easily adhere to the inner wall of the straight pipe. As the number of production batches increases, the residual material will continue to accumulate, not only wasting raw materials but also potentially affecting the quality of subsequent products due to material deterioration. At the same time, the straight pipe lacks effective guidance for the material, making the material flow poorly during the discharge process and easily forming blockages in the pipe, especially when the material contains large particles. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a stirring device that can realize the circulation of food raw materials. It can solve the problem that when dealing with low-viscosity food raw materials with good flowability, such as watery beverages and thin sauces, the straight-cylinder discharge pipe can basically complete the discharge task. However, when dealing with high-viscosity raw materials or materials containing particles, such as red bean paste and peanut butter, the high-viscosity materials are very easy to adhere to the inner wall of the straight-cylinder pipe. As the production batches increase, the residual materials will continue to accumulate, which not only wastes raw materials, but may also affect the quality of subsequent products due to material deterioration. At the same time, the straight-cylinder pipe lacks effective guidance for materials, which makes the materials flow poorly during the discharge process and easily forms blockages in the pipe, especially when the materials contain large particles.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stirring device for realizing the circulation of food raw materials, comprising a stirring tank, a control panel, a feed pipe, a first motor and a conveying pipe, wherein the stirring tank is provided with an inclined discharge pipe assembly; The inclined discharge pipe assembly includes a discharge pipe, a fixed sleeve, and two fixed sliders.

The two T-shaped block slides each have a first fixing bolt groove inside, and the two slides each have a second fixing bolt groove inside. The outer walls of the two fixed sliders are each threaded with two fixing bolts, and the inside of the fixed sleeve is fixedly installed with a guide slide plate.

[0006] Preferably, the discharge pipe is conical and the fixing sleeve is conical; The interior of the mixing tank is connected to the interior of the discharge pipe.

[0007] Preferably, the two slide grooves are used in conjunction with the corresponding T-shaped block slide grooves, and the outer walls of the two fixed sliders are slidably connected to the interior of the corresponding slide grooves. The four fixing bolts are arranged in pairs.

[0008] Preferably, the ends of both sets of fixing bolts near the fixing sleeve are threaded into the T-block groove and the interior of the groove, and are respectively connected to the internal threads of the corresponding second fixing bolt groove and the first fixing bolt groove; When the guide plate component is a flat guide plate, it is used in conjunction with the fixing sleeve.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This stirring device, which enables the circulation of food raw materials, features a tapered discharge pipe in its inclined discharge pipe assembly.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Example 1: Reference Figure 1-4 Example of conventional solid food raw material discharge (planar guide slide plate + conical discharge pipe) This embodiment is applicable to the scenario of mixing conventional solid food raw materials such as flour and rice flour. Through the basic combination of a planar guide slide and a conical discharge pipe, the raw materials are discharged evenly and stably, meeting the needs of daily food processing.

[0023] Structural fit and discharge process: The discharge pipe 10 and the fixed sleeve 12 are both made of 304 stainless steel and have a 30° conical structure to expand the discharge port area. The guide plate 17 is a flat guide plate (thickness 5mm) that fits against the inner wall of the fixed sleeve 12. The fixed slider 8 is locked to the discharge pipe and the fixed sleeve by four fixing bolts 14 (M8 specification) (tightening torque 12N・m).

[0024] During discharge, the raw materials in the mixing tank slide down quickly to the discharge port under the action of gravity along the planar guide slide plate. The conical structure reduces the accumulation of raw materials (accumulation height ≤ 2cm). The discharge speed is stable at 5kg / min. When changing raw materials, loosen the fixing bolts and pull out the fixing sleeve and guide slide plate for cleaning (the whole process takes ≤ 2 minutes).

[0025] Application effects: Suitable for bakeries, rice noodle processing plants and other places, with high output efficiency and no residue, reducing raw material waste rate by 15%, and meeting the continuous output needs of conventional solid food raw materials.

[0026] Example 2: Reference Figure 5 Example of anti-clogging discharge for high-viscosity food raw materials (porous guide slide plate + serrated discharge pipe) This embodiment is designed for mixing highly viscous food ingredients such as red bean paste and jam. It uses a porous guide slide plate and a serrated discharge pipe to prevent the ingredients from sticking and clogging, ensuring smooth discharge.

[0027] Anti-clogging structure optimization: The flow guide plate 17 is replaced with a porous flow guide plate 18 (pore diameter 3mm, opening rate 40%) to disperse the raw material pressure and avoid local adhesion. The inner wall of the discharge pipe 10 is equipped with serrated protrusions (height 2mm, spacing 5mm) to break the sticky structure of the raw material. The clearance between the fixing sleeve 12 and the discharge pipe is increased to 1mm to reduce frictional resistance. The fixing bolt 14 is replaced with a lock nut to prevent vibration from loosening.

[0028] When discharging high-viscosity raw materials, the porous design ensures uniform material flow rate (fluctuation ≤10%), and the serrated protrusions reduce viscous resistance by 30%, increasing the discharge speed to 3kg / min. During equipment operation, the frequency of material blockage is reduced from 3 times per week to 0 times. During cleaning, the high-pressure water gun can quickly remove the residue in the porous structure.

[0029] High viscosity scenario effect: Effectively solves the problem of discharging high viscosity food raw materials, and is suitable for scenarios such as pastry filling processing plants and jam production lines.

[0030] Furthermore, when using this device, the food raw materials to be processed are fed into the mixing tank 1 through the feed pipe 3. The operator starts the device through the control panel 2, and the first motor 4 starts working, driving the stirring shaft 9 to rotate inside the mixing tank 1 to stir the raw materials, thus initially mixing them. Simultaneously, if the raw materials need to be heated to improve fluidity or meet process requirements during the stirring process, the heating tubes arranged in a spiral pattern inside the mixing tank 1 can be activated through the control panel 2. The heating tubes heat the raw materials inside the mixing tank 1, and the continuous stirring of the stirring shaft 9 ensures uniform heating of the raw materials. Then, to achieve sufficient circulation and avoid insufficient mixing in certain areas, the second motor 6 starts under the control of the control panel 2, driving the spiral conveying shaft 7 inside the conveying pipe 5 to rotate. Since the lower end of the conveying pipe 5 is connected to the lower end of the mixing tank 1, when the spiral conveying shaft 7 rotates, its spiral blades push the raw materials from the lower end of the mixing tank 1 into the conveying pipe 5, and convey them upwards along the conveying pipe 5. Finally, the materials are sent back to the upper end of the mixing tank 1 through the connecting pipe at the upper end of the conveying pipe 5, creating a circulation flow between the mixing tank 1 and the conveying pipe 5, ensuring that all raw materials are thoroughly mixed. The raw materials are thoroughly mixed. Once mixing is complete and discharge is required, the mixed materials, under gravity, flow from the mixing tank 1 into the discharge pipe 10, which is connected to the tank's interior. Because the discharge pipe 10 is conical, the raw materials flow towards the discharge port guided by the conical structure. Simultaneously, the guide slide plate 17 within the fixed sleeve 12 further guides the material flow. If a planar guide slide plate is used, material residue and blockage within the discharge pipe 10 can be reduced. If a porous guide slide plate 18 is used, the material is dispersed as it passes through its holes, and larger particles or impurities are filtered out, improving the discharge quality. In practical use, depending on the characteristics of the raw materials and the discharge requirements, when disassembling the fixing sleeve 12, loosen the fixing bolt 14 on the fixing slider 8 so that the fixing bolt 14 disengages from the first fixing bolt groove 11 and the second fixing bolt groove 13. Then push the fixing sleeve 12, and the fixing slider 8 slides along the T-shaped block groove 15 and the groove 16. After the fixing sleeve 12 reaches the appropriate position, retighten the fixing bolt 14 so that the fixing bolt 14 screws into the corresponding first fixing bolt groove 11 and the second fixing bolt groove 13 to fix the fixing sleeve 12, ensuring a stable and efficient discharge process.

[0031] The discharge pipe 10 in the inclined discharge pipe assembly has a conical structure. Under the action of gravity, the material can automatically flow towards the outlet along the inclined pipe wall, reducing the contact area between the material and the pipe wall. With the help of the guide plate component 17 in the fixed sleeve 12, whether it is a flat guide plate or a porous guide plate 18, it can guide the material in a directional manner, so that the material can slide out of the pipe more smoothly during the discharge process, avoiding the accumulation of material in corners or on the pipe wall, reducing raw material waste, and is especially suitable for processing high value-added raw materials, thus reducing production costs.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
