Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and in particular to a beverage concentrate stirring device. Background Technology

[0002] Beverages are products made from one or more edible raw materials, with or without additives, food fortifiers, or other food additives, processed into pre-packaged drinks for direct consumption or reconstitution. These products, containing no more than 0.5% ethanol by mass, are also called beverages or drinks. Examples include carbonated drinks, fruit and vegetable juices and their beverages, protein drinks, and solid beverages. Beverage concentrates require mixing with solutions of varying concentrations. When placed in a container, they are prone to stratification, necessitating a longer stirring time to achieve a uniform consistency.

[0003] Existing stirring devices generally use double or multiple blades for stirring. However, for beverage concentrates, which are mixtures with diverse ingredients and uneven concentrations, different solutions are prone to stratification in the tank due to the influence of solution concentration or density. This results in uneven stirring, low stirring efficiency, and affects the production efficiency of beverages. Utility Model Content

[0004] This utility model addresses the problems in the prior art by providing a beverage concentrate stirring device, which is achieved through the following technical solution:

[0005] A beverage concentrate stirring device includes a tank and a stirring shaft. The stirring shaft is vertically and rotatably installed in the tank. From top to bottom, a top stirring structure, a middle stirring structure, and a bottom stirring structure are installed on the outer ring of the stirring shaft. A motor is fixedly installed on the top of the tank. The output end of the motor passes through the top of the tank and is fixedly connected to the stirring shaft. A feed inlet is opened on one side of the top of the tank. The bottom wall of the tank has a structure that is high in the middle and low on the outer ring. A discharge outlet is opened on one side of the bottom of the tank. A valve is installed on the discharge outlet. A fixing seat is fixedly installed on the bottom of the tank.

[0006] The present invention is further configured such that: the top-level stirring structure includes a spiral sleeve, a blade ring, and multiple blades; the upper outer ring of the stirring shaft is provided with a cross spiral groove for reciprocating movement; a slider is fixedly installed on the inner ring of the spiral sleeve; the slider is slidably installed in the cross spiral groove; the blade ring is rotatably installed on the outer ring of the spiral sleeve; multiple blades are arranged in a ring array and fixed on the outer ring of the blade ring; a limiting rod is fixedly installed on the bottom of the inner top wall of the tank; the limiting rod passes through the side wall of the spiral sleeve and is slidably connected to the spiral sleeve; the bottom of the limiting rod is lower than the bottom of the cross spiral groove.

[0007] The present invention is further configured such that: a threaded groove is provided on the inner side wall of the tank, a sliding rod is fixedly installed on the outer ring of the blade ring, the sliding rod is slidably installed in the threaded groove, and the threaded groove and the cross spiral groove are opened at the same height.

[0008] The present invention is further configured such that: the middle layer stirring structure includes a spiral blade, the spiral blade is spirally installed on the outer ring of the stirring shaft, and the spiral blade is fixedly installed in the middle position of the stirring shaft.

[0009] The present invention is further configured such that: the bottom stirring structure includes a six-bladed inclined blade stirring paddle, which is fixedly installed on the bottom outer ring of the stirring shaft.

[0010] In summary, the beneficial technical effects of this utility model are as follows:

[0011] By sequentially setting a top-layer stirring structure, a middle-layer stirring structure, and a bottom-layer stirring structure on the stirring shaft, the solutions in the upper, middle, and lower parts of the tank are stirred respectively, ensuring uniform stirring and improving stirring efficiency, thereby increasing production efficiency; the paddle blades can move up and down and rotate, stirring the low-concentration solution on the surface to the middle of the tank, further ensuring the stirring effect; the spiral blades can drive the solution to spiral upward along the inner wall of the tank and then converge towards the central cavity, forming an upper and lower convection circulation to achieve the mixing of concentrated slurry; the six-bladed inclined impeller can generate efficient shearing force, making the beverage concentrate form a uniform solution.

[0016] Example

[0017] like Figure 1-2As shown, this utility model discloses a beverage concentrate stirring device, including a tank body 1 and a stirring shaft 2. The stirring shaft 2 is vertically and rotatably installed inside the tank body 1. The outer ring of the stirring shaft 2 is sequentially equipped with a top stirring structure 3, a middle stirring structure 4, and a bottom stirring structure 5 from top to bottom. A motor 6 is fixedly installed on the top of the tank body 1. The output end of the motor 6 passes through the top of the tank body 1 and is fixedly connected to the stirring shaft 2. A feed inlet 7 is opened on one side of the top of the tank body 1. The bottom wall of the tank body 1 has a structure that is high in the middle and low on the outer ring. A discharge outlet 8 is opened on one side of the bottom of the tank body 1. A valve is installed on the discharge outlet 8. A fixing seat 101 is fixedly installed on the bottom of the tank body 1.

[0018] The top-level stirring structure 3 includes a spiral sleeve 301, a blade ring 302, and multiple blades 303. The outer ring of the upper end of the stirring shaft 2 is provided with a cross spiral groove 9 for reciprocating movement. A slider is fixedly installed on the inner ring of the spiral sleeve 301. The slider is slidably installed in the cross spiral groove 9. The blade ring 302 is rotatably installed on the outer ring of the spiral sleeve 301. Multiple blades 303 are arranged in a ring array and fixed on the outer ring of the blade ring 302. A limiting rod 304 is fixedly installed at the bottom of the inner top wall of the tank 1. The limiting rod 304 passes through the side wall of the spiral sleeve 301 and is slidably connected to the spiral sleeve 301. The bottom of the limiting rod 304 is lower than the bottom of the cross spiral groove 9.

[0019] The inner sidewall of the tank body 1 is provided with a threaded groove 10, and a sliding rod 11 is fixedly installed on the outer ring of the blade ring 302. The sliding rod 11 is slidably installed in the threaded groove 10, and the threaded groove 10 and the cross spiral groove 9 are opened at the same height.

[0020] The middle layer stirring structure 4 includes a spiral blade 401, which is spirally mounted on the outer ring of the stirring shaft 2 and fixedly mounted in the middle position of the stirring shaft 2.

[0021] The bottom stirring structure 5 includes a six-bladed inclined blade stirring paddle 501, which is fixedly installed on the bottom outer ring of the stirring shaft 2.

[0022] In this specific implementation example: The raw material solution enters the tank 1 through the inlet 7. The motor 6 drives the stirring shaft 2 to rotate. The rotation of the stirring shaft 2 drives the spiral sleeve 301 to move back and forth along the cross spiral groove 9, thereby driving the blade ring 302 to move up and down. Under the action of the threaded groove 10 and the sliding rod 11, the rotation of the blade ring 302 drives the blade 303 to rotate for stirring. The rotation of the stirring shaft 2 also drives the spiral blade 401 to rotate, causing the solution in the tank 1 to spiral upward along the inner wall of the tank 1 and then converge towards the central cavity, forming an up-and-down convection circulation to achieve the mixing of the concentrated slurry. The rotation of the stirring shaft 2 also drives the six-bladed inclined blade stirring paddle 501 to rotate. The rotation of the six-bladed inclined blade stirring paddle 501 can generate a high-efficiency shearing force, so that the beverage concentrate forms a uniform solution.
