Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of food processing, and particularly relates to a nutrition formula food additive premixing device. BACKGROUND

[0002] Nutrition formula food is food designed for specific groups of people or specific nutritional needs, and its purpose is to provide balanced and comprehensive nutritional support. These foods usually contain a variety of nutrients such as protein, carbohydrates, fats, vitamins, minerals and fiber. They can be used as a supplement or replacement for diet to meet the body's needs for various nutrients. During the processing of nutrition formula food, food additives are often added to the inside to add various elements or necessary ingredients. During the addition of food additives, a premixing device is often used to assist in the mixing of additives.

[0003] At present, the premixing device for food additives mainly consists of a premixing tank and a stirring and mixing assembly. In actual use, various additives are added to the inside of the premixing tank, and the stirring assembly is started to stir the internal raw materials, thereby realizing the mixing and stirring process. Although this stirring method can effectively mix the raw materials, when facing powder-like additives, some powder will adhere to the pipe wall due to the distance between the stirring assembly and the pipe wall, which will affect the overall mixing effect. Therefore, how to compatibly mix liquid and powder-like additives is a problem to be solved.

[0004] During the premixing process of nutrition formula food additives, when the raw materials in the premixing tank are mixed, the raw materials in the premixing tank are discharged and sent to the subsequent mixing tank for secondary mixing. When the raw materials are discharged, some of the raw materials will adhere to the pipe wall. In the batch production process, in order to prevent contamination of the subsequent processing process, the premixing tank and the stirring assembly need to be separated after the first mixing, and manual cleaning is required before they can be used again. However, in batch processing, such frequent disassembly and cleaning of the premixing tank undoubtedly affect the overall efficiency. SUMMARY

[0049] Working principle and use process:

[0050] Before use, it is necessary to ensure that there is no residual additive in the mixing tank 6, and at the same time, the mixing tank 6 needs to be placed below the four premixing tanks 9, ensuring that the bottom ends of the four premixing tanks 9 are located inside the mixing tank 6. At the same time, multiple additives need to be injected into the inlet 10 to enter the inside of the premixing tank 9 for mixing, and at the same time, the power of the device needs to be connected, and the input end of the water inlet pipe 14 needs to be connected with the external water source, and at the same time, it is necessary to ensure that the water inlet pipe 14 can rotate normally, and the preparation before mixing is completed.

[0051] After the preparation is completed, the motor 2 can be turned on to drive the driving gear 3 to rotate, at this time, the multiple driven gears 4 located on the outer side of the driving gear 3 rotate, and at the same time, the bottom end of the main shaft 11 is rotated to provide power for premixing.

[0052] When the liquid raw material enters the inside of the premixing tank 9, the rotation of the main shaft 11 can synchronously drive the circumferential rotation of the mixing assembly 18 on the outer side, at this time, the stirring mechanism composed of the mounting frame 181, the rubber plate 184 and the connecting rod 188 can fully mix the raw materials in the premixing tank 9. When the powder raw material enters the inside of the premixing tank 9, part of the raw material will adhere to the inner wall of the premixing tank 9, at this time, the external water source can be opened to input the water flow into the inside of the water inlet pipe 14 and the liquid storage tank 13, and at the same time, the valve of the water inlet pipe 1812 can be opened to input the water flow into the inside of the water storage pipe 189. With the input of the water flow, the piston plate 1811 is driven by the acting force to displace the piston plate 1811 towards the water inlet pipe 1812, at this time, the piston rod 1810 is synchronously displaced, at this time, the clamping block 1814 slides relative to the clamping groove 186, that is, the clamping block 1814 displaces towards the first fixed seat 182, at the same time, the connecting rod 188 deflects and gives the rubber plate 184 a pushing force, at this time, the rubber plate 184 rotates around the mounting block 185 and approaches the inner wall of the premixing tank 9, until it is attached to the inner wall of the premixing tank 9. At this time, the rubber plate 184 can clean the inner wall of the premixing tank 9 to avoid the adhesion of the raw material, and the mixing process of the powder raw material is completed.

[0053] After the pre-mixing of the additives is completed, the raw materials in the pre-mixing tank 9 can be completely discharged by opening the valve of the discharge valve 15, and at this time the raw materials can enter the inside of the mixing tank 6. Due to the continuous rotation of the driving gear 3, the bottom end of the stirring shaft 7 is rotated synchronously, and at this time the stirring paddle 8 on the outside of the stirring shaft 7 stirs the raw materials in the mixing tank 6 again, so that the raw materials are fully mixed, and the secondary mixing process is completed.

[0054] When the pre-mixing tank 9 is fully mixed, the raw materials in the pre-mixing tank 9 can be completely discharged, and the valve of the discharge valve 15 is closed. If the rubber plate 184 is attached to the inner wall of the pre-mixing tank 9 at this time, the position of the rubber plate 184 is not adjusted, otherwise the rubber plate 184 is adjusted to be attached to the inner wall of the pre-mixing tank 9. When the rubber plate 184 is attached to the inner wall of the pre-mixing tank 9, the piston plate 1811 is located on the left side of the water storage pipe 189 at this time, and the valve of the drain pipe 1813 is opened to output and spray water flow to the inner wall of the pre-mixing tank 9. At this time, due to the rotation of the main shaft 11, the rubber plate 184 can slide relative to the inner wall of the pre-mixing tank 9 synchronously, and the automatic cleaning of the pre-mixing tank 9 can be realized by the action of the water flow and the friction force, and the self-cleaning process is completed.

[0055] Although the embodiments of the present application have been shown and described, it is understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
