[0001] This utility model relates to the field of food processing technology, and in particular to a high-efficiency vacuum food processing mixing tank. Background Technology
[0002] A vacuum food processing mixing tank is a piece of equipment used in food production. It combines a vacuum environment with a mixing function, primarily to improve the efficiency and quality of food processing. It removes air from a sealed container, creating a negative pressure environment. This reduces oxidation, inhibits microbial growth, and maintains food freshness, while ensuring uniform texture and color during mixing. It is commonly used in the production of jams, condiments, and meat products to improve food quality and extend shelf life.
[0003] Existing vacuum food processing mixing tanks mainly rely on motor-driven single-axis stirring components for internal mixing. However, this single-axis driving method has limitations in practical operation, such as uneven mixing, resulting in incomplete food mixing and difficulty in achieving efficient vacuum processing.
[0004] Therefore, those skilled in the art have provided a high-efficiency vacuum food processing mixing tank to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency vacuum food processing mixing tank. This tank utilizes a dual mixing mechanism formed by the rotation of the mixing drum and the stirring rod, effectively improving the uniformity and fineness of food mixing and solving the problem of uneven mixing in a single axis. Simultaneously, vacuum evacuation technology reduces oxidation and microbial growth inside the mixing drum, ensuring food quality and extending shelf life.

[0015] 1. This utility model proposes a high-efficiency vacuum food processing mixing tank.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 An embodiment of this utility model provides: a high-efficiency vacuum food processing mixing tank, including a main frame 1 and a mixing drum 2. A round shaft 3 is fixedly connected to the center of the rear end face of the mixing drum 2. The middle part of the shaft body of the round shaft 3 is fixedly set in the middle of the upper end face of the rear side of the main frame 1 through a bearing. A first motor 4 is fixedly set in the middle of the lower end face of the rear side of the main frame 1. A stirring mechanism 5 is set at the center of the front end face of the mixing drum 2. Two rollers 6 are symmetrically fixedly set on the upper end face of the front side of the main frame 1. An annular groove 7 is opened on the outer surface of the mixing drum 2 near the front end. The outer surfaces of the two rollers 6 are in contact with the bottom surface of the groove of the annular groove 7. A vacuum pump 10 is fixedly set at the upper end of the rear end face of the mixing drum 2. An air pipe 12 is fixedly connected to the output end of the vacuum pump 10. The air pipe 12 passes through the rear end face of the mixing drum 2 and leads to the interior. A pressure relief port 11 is opened at the rear end of the upper end of the mixing drum 2.
[0026] Specifically, the first motor 4 drives the mixing drum 2 to rotate. When the mixing drum 2 rotates, it will roll on the two rollers 6 because the annular groove 7 is opened on the outer surface of the drum body near the front end. In this way, it provides support for the front end of the mixing drum 2 and provides stable guidance for the rotation of the mixing drum 2. In addition, in order to prevent the mixing drum 2 from falling off the rollers 6 due to excessive speed, the first motor 4 adopts low speed drive. Furthermore, a filter screen is installed at the opening of the air pipe 12 inside the mixing drum 2 to prevent food from clogging the air pipe 12 and causing the vacuum pump 10 to be unable to pump air. The pressure relief port 11 is a manual valve.
[0027] Reference Figure 2 , Figure 3 , Figure 5 The output end of the first motor 4 and one end of the round shaft 3 are respectively fixed with pulleys, and a belt is connected between the two pulleys. The upper middle part of the mixing drum 2 is provided with a feeding port 8, and the lower middle part of the mixing drum 2 is provided with a discharge port 9. The four corners of the lower end of the main frame 1 are all fixed with support legs 13.
[0028] Specifically, both the feeding port 8 and the discharge port 9 adopt a sealed valve switch design to prevent the vacuum state inside the mixing drum 2 from being destroyed due to possible air leakage. In order to prevent the belt from slipping during use, the inner surface of the belt is made of anti-slip material.
[0029] Reference Figure 3 , Figure 4 The stirring mechanism 5 includes a second motor 501, which is fixedly installed at the center of the front end face of the stirring drum 2. The output end of the second motor 501 passes through the front end face of the stirring drum 2 and extends into the interior. A long rod 502 is fixedly installed at the output end of the second motor 501. One end of the long rod 502 is rotatably installed at the center of the rear inner wall of the stirring drum 2. Multiple stirring rods 503 are fixedly installed on the long rod 502 and are evenly distributed along the long rod 502.
[0030] Specifically, the second motor 501 drives the long rod 502 to rotate, which in turn drives multiple stirring rods 503 to continuously stir and tumble the food inside the stirring drum 2. The stirring rods 503 are arranged in alternating long and short positions to cover different stirring depths, and the speed of the second motor 501 can be selected according to the needs of the operator.
[0031] Working principle: The operator first opens the valve of the feeding port 8, then puts the food to be processed into the inside of the mixing drum 2, and then closes the valve. Then the power is turned on, and the first motor 4, the second motor 501 and the vacuum pump 10 start to work. The first motor 4 drives the pulley at its output end to rotate, and the pulley drives the pulley on one end of the round shaft 3 to rotate through the belt, which in turn drives the round shaft 3 to rotate with the bearing as the support point. The rotation of the round shaft 3 will drive the mixing drum 2 to rotate, so that the food inside the mixing drum 2 will continuously tumble. When the mixing drum 2 rotates, the annular groove 7 opened at the front end of its outer surface will roll in contact with the two rollers 6. At the same time, the second motor 501 drives the long rod 502 to rotate with the center of the rear inner wall of the mixing drum 2 as the fulcrum. The rotation of the long rod 502 will drive the multiple stirring rods 503 on its rod to stir and process the food inside the mixing drum 2. With the continuous tumbling of the mixing drum 2 and the continuous stirring of the stirring rods 503, the food is processed and stirred efficiently.
[0032] Secondly, when the vacuum pump 10 starts working, the vacuum pump 10 will evacuate the air inside the mixing drum 2 through the air pipe 12 to form a vacuum state. Then, after processing is completed, the operator turns off the power, releases the pressure by opening the pressure relief port 11, and then opens the valve of the discharge port 9. The processed food is discharged from the discharge port 9.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
