Description

Technical Field

[0001] The invention relates to a stirring device, in particular to a mixing and stirring device for preparing mung bean protein gel. Background Art

[0002] Milk is one of the oldest natural beverages. It is rich in nutrients such as protein, fat, vitamins and minerals and is known as white blood. Milk protein contains essential amino acids for the human body, and milk fat is mostly short-chain and medium-chain fatty acids, which are easily absorbed by the human body. Although milk is rich in various nutrients, it is not a food that is easy for everyone to digest and absorb. For special groups with metabolic diseases and allergies (such as lactose intolerance and milk protein allergy), the main treatment method is to eliminate milk intake from the diet.

[0003] Today's consumers are gradually pursuing a healthy diet with low sugar, low salt and low fat. With the increasing attention to nutrients and calories and the increasing prevalence of hypercholesterolemia, more and more people are choosing low-calorie beverages such as plant milk that are rich in dietary fiber, minerals, vitamins and antioxidants and are cholesterol-free.

[0004] Among plant-based milk sources, soy is widely used due to its protein quantity, quality, and functional properties. Compared to traditional animal-based milks, soy milk lacks textural density. The application of soy protein in the food industry has been limited by its abrasive properties, which result in a harsh taste, as well as its poor functional properties, including solubility, gelling ability, and emulsifying activity.

[0005] In order to improve the taste of mung bean protein, the inventors discovered during the experiment that mung bean protein microgel is a solution that can improve the taste. However, the current preparation method is limited to the experimental process. Therefore, a separate stirring device is required for batch production, and further improvements are needed for this purpose. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a mixing and stirring device for the preparation of mung bean protein gel, which can assist in the implementation of experimental projects, provide greater implementation space for projects to improve the taste of mung bean protein drinks, and facilitate the production of mung bean protein drinks.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a mixing and stirring device for preparing mung bean protein gel, comprising a container shell, a stirring assembly disposed within the container shell, a cylindrical filter screen further disposed within the container shell, a plurality of fixed auxiliary blades disposed on the filter screen, the stirring assembly comprising a stirring shaft and stirring blades, the stirring blades being fixed to the stirring shaft and driven to rotate by the stirring shaft; the auxiliary blades having an inclined surface facing the direction of material flow;

[0008] There is a gap between the side of the stirring blade and the auxiliary blade for crushing the material, or

[0009] The auxiliary blade is elastic, and one side of the auxiliary blade corresponding to the stirring blade abuts against the stirring blade, and cooperates with the stirring blade to perform grinding.

[0010] As a further improvement of the present invention, the auxiliary blade is provided with a frosted surface on one side corresponding to the stirring blade, and is attached to the edge of the stirring blade by elastic force, cooperating with each other to grind the material.

[0011] As a further improvement of the present invention, the auxiliary blade is provided with a mesh having the same mesh as the filter screen on the surface facing the material flow direction; the screened material enters between the filter screen and the container shell.

[0012] As a further improvement of the present invention, when the stirring blade rotates, the auxiliary blade intermittently cooperates with each blade to form vibration, so as to shake off the material on the auxiliary blade and the frosted surface.

[0013] As a further improvement of the present invention, the stirring blades are driven by the stirring shaft to rotate and transfer the material upward.

[0014] As a further improvement of the present invention, a surface of the auxiliary blade corresponding to the stirring blade is set as a curved surface, and the curved surface is adapted to the motion trajectory of the outer edge of the stirring blade.

[0015] As a further improvement of the present invention, the distance between the downward end of the auxiliary blade corresponding to the stirring blade and the stirring shaft is smaller than the distance between the upward end and the stirring shaft, and a slope is formed in the cross section; the outer edge of the stirring blade is adapted to the slope formed on the auxiliary blade.

[0016] The beneficial effects of the present invention are that the particles can be crushed by stirring through the stirring device, thereby improving the taste while preventing the particles from being too large and affecting the taste, and the particles can be screened to achieve particle size control, which is suitable for batch production.

[0024] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0025] Reference Figure 1-6 As shown,

[0026] A mixing and stirring device for preparing mung bean protein gel comprises a container housing 1, a stirring assembly 2 disposed within the container housing 1, a cylindrical filter screen 3 further disposed within the container housing 1, a plurality of fixed auxiliary blades 31 disposed on the filter screen 3, the stirring assembly 2 comprising a stirring shaft 21 and stirring blades 22, the stirring blades 22 being fixed to the stirring shaft 21 and driven to rotate by the stirring shaft 21; the auxiliary blades 31 are provided with an inclined surface facing the direction of material flow;

[0027] There is a gap between the side of the stirring blade 22 and the auxiliary blade 31 for crushing the material, or

[0028] The auxiliary blade 31 is elastic and has a side corresponding to the stirring blade 22 that abuts against the stirring blade 22 to cooperate with the stirring blade 22 for grinding.

[0029] In the above scheme, the mixed material that meets the standards can be screened through the filter screen 3 and enter the space between the filter screen 3 and the container shell 1. Since the filter screen 3 has a certain flow resistance, it can limit the screened material from returning to the filter screen 3 to a certain extent. The stirring blade 22 can not only be used to mix the material, but also can make the material flow regularly by stirring, thereby improving the mixing effect. In addition, the inclined surface of the auxiliary blade 31 can provide a guiding effect. And the cooperation relationship between the auxiliary blade 31 and the stirring blade 22 can form the following two schemes:

[0030] 1. There is a gap between the stirring blade 22 and the auxiliary blade 31. Through this solution, the gap can be used to crush the material, achieve uniform mixing of the material, and cooperate with the filter screen 3 to achieve screening.

[0031] 2. The auxiliary blade 31 is elastic and abuts against the edge of the stirring blade 22. This cooperation can achieve grinding. The stirring blade 22 generally has a certain spiral or inclined shape, and its edge can cooperate with the auxiliary blade 31 to scrape and sweep, thereby achieving a grinding effect.

[0032] The above two solutions can quickly mix and break up the materials, improving the stirring effect. The cylindrical filter 3 can be used to throw out the materials under the centrifugal force and filter them together with the filter 3. Generally speaking, the flow rate at the outer diameter position is lower, which can collect the sieved materials to a certain extent.

[0033] The taste of mung bean protein can be improved by adding gel. The stirring device can be used to break up the particles, thereby improving the taste while preventing the particles from being too large. The particles can be sieved to achieve particle size control, making it suitable for batch production.

[0034] The filter screen 3 can be fixed in the container shell 1 by a simple connecting rod, which only needs to be kept relatively fixed without affecting the auxiliary leaves 31 or their own elasticity and deformation.

[0035] In order to improve the grinding effect, the auxiliary blade 31 is provided with a frosted surface 311 on one side corresponding to the stirring blade 22 and is elastically attached to the edge of the stirring blade 22 to cooperate with each other to grind the material.

[0036] The frosted surface 311 can cooperate with the auxiliary blade 31 to grind and achieve particle control. In addition, the frosted surface 311 has a larger resistance and a rough surface, so it can achieve a better grinding effect and alleviate the problem that gel-state materials are difficult to retain and grind.

[0037] In order to further increase the screening area, the auxiliary blade 31 is provided with a mesh having the same mesh as the filter 3 on the front side facing the material flow direction; the screened material enters between the filter 3 and the container shell 1.

[0038] The mesh on the auxiliary leaf 31 can increase the screening area and improve the screening effect. Figure 2 and 3 shown.

[0039] Based on the above-mentioned implementation method of the auxiliary leaf 31 having elastic force, the following effect can also be achieved: when the stirring blade 22 rotates, the auxiliary leaf 31 intermittently cooperates with each blade to form vibration to shake off the material on the auxiliary leaf 31 and the frosted surface 311.

[0040] Since the stirring blade 22 is composed of multiple blades, it will produce intermittent cooperation when cooperating with the auxiliary blade 31. Since the blade and the auxiliary blade 31 are in abutment with each other, vibration will be generated when the two are in contact. At this time, the material on the auxiliary blade 31 and the frosted surface 311 can be shaken off, avoiding blockage of the screening and preventing the frosted surface 311 from being filled with material and affecting the grinding effect.

[0041] In the specific setting, the filter screen 3 is also elastic, the number of auxiliary leaves 31 is 6, and the number of blades of the stirring blade 22 is also 6, and they are all equally divided along the circumference. At this time, when each blade contacts the corresponding auxiliary leaf 31, all the blades will synchronously contact the corresponding auxiliary leaf 31, and because the filter screen 3 and the auxiliary leaf 31 are elastic, and when the auxiliary leaf 31 and the blade are in contact, the auxiliary leaf 31 will be deformed, and the filter screen 3 will be deformed at this time, the vibration range is wider, and the effect of shaking off the material is better. In addition, when the blade is separated from the auxiliary leaf 31, the filter screen 3 and the auxiliary leaf 31 will shake, and another vibration will be formed at this time, further improving the shaking off effect. You can also refer to Figure 6 As shown in FIG, the number of auxiliary blades 31 is 5, and the number of stirring blades 22 is 10, which can also achieve the above technical effects. Figure 4 As shown in the figure, there are 8 auxiliary blades 31 and 10 stirring blades 22. Each time, two auxiliary blades 31 and two stirring blades 22 will be in contact with each other. The vibration frequency formed will be higher and more intense, and the shaking-off effect will be better. Technical personnel in this field can choose according to their needs.

[0042] In order to improve the material mixing effect, the stirring blades 22 are driven by the stirring shaft 21 to rotate and transfer the material upward.

[0043] The solution can convey the material upward to achieve a mixing effect. After the material is shaken off from the filter screen 3 and the auxiliary leaves 31, the material is conveyed upward and circulated and stirred.

[0044] In addition, in order to further improve the coordination between the auxiliary blade 31 and the stirring blade 22, the side of the auxiliary blade 31 corresponding to the stirring blade 22 is set as a curved surface 4, and the curved surface 4 is adapted to the motion trajectory of the outer edge of the stirring blade 22. The design of the curved surface 4 can increase the grinding area and make the stirring and mixing efficiency higher. Figure 5 、 6 shown.

[0045] In a further configuration, the distance between the downward end of the auxiliary blade 31 corresponding to the stirring blade 22 and the stirring shaft 21 is smaller than the distance between the upward end and the stirring shaft 21, and a slope is formed in the cross section; the outer edge of the stirring blade 22 is adapted to the slope formed on the auxiliary blade 31.

[0046] Reference Figure 5 、 6 As shown in , the position of the auxiliary blade 31 corresponding to the stirring blade 22 is inclined in cross section, which can further increase the matching area and also increase the screening area.

[0047] In practice, the auxiliary blades 31 can be formed by directly bending the filter screen 3, and the grinding surface is fixed on the filter screen 3 by welding. The grinding surface can be made of frosted ceramic plates or steel plates, which can cooperate with the blades. This structure is more convenient to produce.

[0048] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
