Description

Technical Field

[0001] The utility model relates to the technical field of beverage mixing equipment, in particular to a mixing equipment for coffee-type milk beverage. Background Art

[0002] Prepared beverages have developed very rapidly in recent years, especially the application of high-temperature instantaneous sterilization and aseptic packaging in prepared milk-containing beverages, which retain the nutritional components of milk to the greatest extent, making prepared milk-containing beverages characterized by diverse tastes, high nutritional value and convenient drinking. Prepared milk-containing beverages are beverages made from milk or dairy products, water, white sugar and (or) sweeteners, acidulants, fruit juice, tea, coffee, plant extracts, etc. Among them, coffee-type milk beverages not only have the unique bitterness of coffee, but the combination of coffee and milk can also form a smooth taste and good flavor.

[0003] Due to the interaction between milk components and coffee components, and the heat sterilization during beverage manufacturing, the original stable structure of milk products is changed, so that during the storage period (especially during long-term storage), coffee in the formulated milk-containing beverage has the disadvantages of easy precipitation and low stability, and the precipitation leads to quality degradation. For this reason, the applicant solves the problem of coffee precipitation by adding a small amount of thickener and stabilizer for mixing and stirring. At present, the mixing equipment used includes a mixing drum and a stirring blade. The stabilizer is first added to the beverage for stirring and mixing. After the stabilizer stabilizes the various components in the beverage, the thickener is added for stirring and mixing. However, the order of adding the stabilizer and the thickener depends on manual control, and the stabilizer and the thickener are manually added from the top of the mixing drum. It takes a certain amount of time for the stabilizer and the thickener to diffuse downward to the bottom of the mixing drum, resulting in a prolonged stirring time. The increase in stirring time will affect the stabilizing effect of the stabilizer, and there will also be a problem of uneven diffusion, which cannot effectively solve the problem of coffee precipitation during product storage. Utility Model Content

[0004] The utility model aims to provide a mixing device for coffee-type milk beverages to solve the problem that it takes a certain time for stabilizers and thickeners to diffuse downward to the bottom of a mixing barrel in the prior art, resulting in prolonged stirring time and affecting the stabilizing effect of the stabilizer.

[0005] In order to achieve the above object, the utility model provides the following technical solutions:

[0006] A mixing device for a coffee-type milk beverage comprises a mixing barrel, a support plate is provided on the top of the mixing barrel, a stirring shaft is rotatably connected to the support plate, a feeding barrel is also fixedly provided on the support plate, the stirring shaft and the feeding barrel both extend into the bottom of the mixing barrel, and the support plate is provided with a first motor that drives the stirring shaft to rotate; the feeding barrel is evenly spaced from top to bottom with a plurality of through holes, the inner periphery of the feeding barrel is also coaxially rotatably connected with a feeding tube, the outer periphery of the feeding tube is in contact with the inner periphery of the feeding barrel, the feeding tube is coaxially provided with a first feeding chamber and a second feeding chamber extending to the bottom of the feeding barrel, the first feeding chamber and the second feeding chamber are both provided with feeding holes alternately aligned with the plurality of through holes, and the support plate is provided with a second motor that drives the feeding tube to rotate.

[0007] The working principle and beneficial effects of the utility model:

[0008] In this solution, the milk beverage is added into the mixing cylinder. At this time, the feeding holes and the multiple through holes on the first feeding chamber and the second feeding chamber are not aligned, and the inner peripheral wall of the feeding cylinder closes all the feeding holes, so that the first feeding chamber and the second feeding chamber are in a sealed state.

[0009] The stabilizer is added into the first feeding chamber and the thickener is added into the second feeding chamber. Since the feeding cylinder extends to the bottom of the mixing cylinder, the first feeding chamber and the second feeding chamber extend to the bottom of the feeding cylinder, so that the first feeding chamber and the second feeding chamber also extend to the bottom of the mixing cylinder, and the feeding tube is rotatably connected to the inner circumferential wall of the feeding cylinder. Therefore, at this time, the feeding tube is driven to rotate by the second motor so that the multiple feeding holes and the multiple through holes on the first feeding chamber are aligned respectively, and the stabilizer flows into the mixing cylinder through the multiple feeding holes and the multiple through holes, and then the stirring shaft is driven to rotate by the first motor for stirring and mixing; similarly, after stirring and mixing for a period of time, the feeding tube is driven to rotate by the second motor so that the multiple feeding holes and the multiple through holes on the second feeding chamber are aligned respectively, and the thickener flows into the mixing cylinder through the multiple feeding holes and the multiple through holes, and is stirred and mixed with the milk beverage.

[0010] The present solution utilizes a first feeding chamber and a second feeding chamber extending to the bottom of the mixing barrel. When a stabilizer and a thickener are added, they flow out through a plurality of feeding holes and a plurality of through holes. The stabilizer and the thickener diffuse synchronously from the upper, middle and lower layers of the milk beverage. The stabilizer, the thickener and the milk beverage are quickly mixed, thus shortening the mixing time and further shortening the stirring time, improving the stabilizing effect of the stabilizer, and thus solving the problem of coffee precipitation. Furthermore, by driving the feeding tube to rotate by the second motor, the order of adding the stabilizer and the thickener can be controlled.

[0011] Furthermore, the first motor and the second motor are both servo motors. A servo motor is a commonly used mechanical transmission part in the art. It is a motor that can convert an electrical signal into a mechanical motion. It can control the current of the motor to rotate the active end of the motor to a desired position and maintain the position. The servo motor has a self-locking function, and the feeding tube remains stationary under the self-locking effect of the servo motor.

[0012] Furthermore, a drain valve is provided at the bottom of the mixing cylinder, and the milk beverage in the mixing cylinder is drained by the drain valve.

[0013] Furthermore, the number of the through holes is 6 to 12. The stabilizer or thickener is quickly discharged into the mixing barrel through the multiple through holes.

[0014] Furthermore, the through hole is provided with a one-way valve which is connected to the mixing barrel, so that the stabilizer or thickener can flow into the mixing barrel in one direction through the one-way valve, thereby increasing the flow rate of the stabilizer or thickener.

[0015] Furthermore, the support plate is fixed with a cylinder, and the movable end of the cylinder is fixed with a pressing plate for pressing the first feeding chamber and the second feeding chamber downwards. The pressing plate is used to press the stabilizer or thickener so that the stabilizer or thickener is discharged through the through hole at an accelerated speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In the following statements, directional words such as "left", "right", "up", and "down" are all based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0023] Embodiment: A mixing device for a coffee-type milk beverage, such as Figure 1 As shown, it includes a mixing barrel 2, which is fixed with a liquid inlet 4 and a liquid discharge valve 1. A support plate 14 is fixed on the top of the mixing barrel 2, and the support plate 14 is rotatably connected to a stirring shaft 3. The support plate 14 is also fixed with a feeding barrel 8, and the stirring shaft 3 and the feeding barrel 8 both extend into the bottom of the mixing barrel 2. The support plate is fixed with a first motor 5 that drives the stirring shaft 3 to rotate;

[0024] like Figure 2 , the feeding barrel 8 is evenly spaced with 14 through holes 7 from top to bottom, the inner periphery of the feeding barrel 8 is also coaxially connected with a feeding pipe 9, the outer periphery of the feeding pipe 9 is in contact with the inner periphery of the feeding barrel 8, and the feeding pipe 9 is fixed with a partition 13 that divides its internal space into a first feeding chamber 11 and a second feeding chamber 12. The first feeding chamber 11 and the second feeding chamber 12 are both provided with feeding holes 10 that are alternately aligned with the 14 through holes 7, and the support plate 14 is also fixed with a second motor 6 that drives the feeding pipe 9 to rotate. The first motor 5 and the second motor 6 are both servo motors.

[0025] like Figure 2 As shown, in this solution, the milk beverage is added into the mixing barrel 2. At this time, the feeding holes 10 and the 14 through holes 7 on the first feeding chamber 11 and the second feeding chamber 12 are not aligned, and the inner peripheral wall of the feeding barrel 8 closes all the feeding holes 10, so that the first feeding chamber 11 and the second feeding chamber 12 are in a sealed state.

[0026] The stabilizer is added into the first feeding chamber 11, and the thickener is added into the second feeding chamber 12. Since the feeding cylinder 8 extends to the bottom of the mixing cylinder 2, the first feeding chamber 11 and the second feeding chamber 12 extend to the bottom of the feeding cylinder 8, so that the first feeding chamber 11 and the second feeding chamber 12 also extend to the bottom of the mixing cylinder 2, and the feeding pipe 9 is rotatably connected to the inner peripheral wall of the feeding cylinder 8. Therefore, Figure 3 and Figure 4 As shown, at this time, the feeding tube 9 is driven to rotate by the second motor 6, so that the 14 feeding holes 10 and the 14 through holes 7 on the first feeding chamber 11 are aligned respectively, and the stabilizer flows into the mixing barrel 2 through the 14 feeding holes 10 and the 14 through holes 7, and then the stirring shaft 3 is driven to rotate by the first motor 5 for stirring and mixing; similarly, after stirring and mixing for a period of time, the feeding tube 9 is driven to continue to rotate by the second motor 6, so that the 14 feeding holes 10 and the 14 through holes 7 on the second feeding chamber 12 are aligned respectively, and the thickener flows into the mixing barrel 2 through the 14 feeding holes 10 and the 14 through holes 7, and is stirred and mixed with the milk beverage.

[0027] The present solution utilizes the first feeding chamber 11 and the second feeding chamber 12 extending to the bottom of the mixing barrel 2. When the stabilizer and the thickener are added, they flow out through the 14 feeding holes 10 and the 14 through holes 7. The stabilizer and the thickener diffuse synchronously from the upper, middle and lower layers of the milk beverage. The stabilizer, the thickener and the milk beverage are quickly mixed, the mixing time is shortened, and then the stirring time is shortened, the stabilizing effect of the stabilizer is improved, and the problem of coffee precipitation is solved. Moreover, by driving the feeding tube 9 to rotate through the second motor 6, the order of adding the stabilizer and the thickener can be controlled.
