Description

Technical Field

[0001] This utility model relates to the field of plant protein beverage production technology, and in particular to a mixing tank for plant protein beverage production. Background Technology

[0002] In the production of plant-based protein beverages, the mixing tank is one of the core pieces of equipment, primarily used for mixing, homogenizing, and adjusting the physicochemical properties of the beverage. Because plant proteins (such as soybeans, oats, and walnuts) have poor solubility in water and are prone to sedimentation or stratification, they require thorough stirring, emulsification, and stabilization in the mixing tank to ensure a uniform taste and high stability. Furthermore, the mixing tank is also used to add adjuncts such as sugars, emulsifiers, and stabilizers to meet the flavor, texture, and shelf-life requirements of the final product. Therefore, the performance of the mixing tank directly affects the quality and production efficiency of plant-based protein beverages.

[0003] However, existing mixing tanks still have the following drawbacks: they are prone to material adhesion and residue problems; plant proteins easily adhere to the tank walls and stirring components, leading to material waste, reduced yield, difficult cleaning, and increased risk of microbial contamination. Secondly, the open feeding method exposes the mixing process to air, making plant proteins prone to oxidation, such as the rancid taste produced by fat oxidation in walnut milk. Furthermore, the internal stirring structure of existing mixing tanks is complex, making subsequent cleaning relatively troublesome. Therefore, further improvements are needed. To this end, we have proposed a mixing tank for the production of plant protein beverages. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a mixing tank for the production of plant protein beverages.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mixing tank for producing plant protein beverages, comprising a tank body, a top cover fixed to the top of the tank body, a top shell fixed to the middle of the upper surface of the top cover, a bushing rotatably connected to the middle of the top cover via a bearing, a stirring assembly passing through the bushing, a plurality of wall scraping assemblies fixed to the bottom of the bushing inside the tank body, a motor for driving the stirring assembly to rotate fixed to the upper surface of the top shell, a linkage assembly installed on the inner side of the top shell, the motor driving the bushing to rotate via the linkage assembly, a feed pipe and a one-way exhaust valve fixed to both sides of the top cover respectively, a first one-way valve installed in the middle of the feed pipe, an air inlet pipe passing through and fixed to the side wall of the bottom of the tank body, a discharge pipe fixed to the middle of the bottom of the tank body, and a controller installed on the upper surface of the top cover.

[0006] Furthermore, an electric heating mechanism is installed inside the tank.

[0007] Furthermore, the bottom of the tank is cone-shaped, and a valve is installed in the middle of the discharge pipe.

[0008] Furthermore, a second one-way valve is fixedly connected to the bottom end of the air intake pipe, and the other end of the air intake pipe is connected to a nitrogen gas supply unit.

[0009] Furthermore, the stirring assembly includes a vertical shaft that passes through the bushing and is rotatably connected to the bushing via a bearing. The top end of the vertical shaft is fixedly connected to the motor output shaft, and the bottom end of the vertical shaft is fixed with stirring blades.

[0010] Furthermore, the linkage assembly includes a side shaft rotatably connected to the top wall of the top shell, with a second gear and a third gear fixedly connected to the top and bottom ends of the side shaft, respectively. A first gear is fixedly connected to the motor output shaft, and a fourth gear is fixed to the surface of the bushing. The first gear meshes with the second gear, and the size of the first gear is smaller than that of the second gear. The third gear meshes with the fourth gear, and the size of the third gear is smaller than that of the fourth gear.

[0011] Furthermore, the wall scraping assembly includes a crossbar fixed to the outer wall of the bushing, and a scraper is fixedly connected to the other end of the crossbar, the scraper being in contact with the inner wall of the tank.

[0012] The beneficial effects of this utility model are: 1. In use, this utility model includes a tank body, a top cover, a bushing, a wall scraping assembly, a stirring assembly, a motor, a linkage assembly, a feed pipe, and a discharge pipe. With the linkage assembly connected, the motor can simultaneously drive the stirring assembly to rotate rapidly and the wall scraping assembly to rotate slowly, thereby achieving automatic wall scraping while stirring, preventing plant proteins (such as soybeans and oats) from adhering to the inner wall of the tank and avoiding material waste. The internal structure of this mixing tank is designed to be simpler, which also facilitates subsequent cleaning.

[0013] 2. When using this utility model, an air inlet pipe and a one-way exhaust valve are provided. The feeding pipe adopts a closed feeding method. Food-grade nitrogen is filled into the tank through the air inlet pipe. The nitrogen is used to squeeze out the air in the tank. When the nitrogen enters from the bottom of the tank, it causes the beverage to tumble, which not only improves the stirring efficiency, but also avoids the oxidation of plant protein, such as the rancid taste produced by the oxidation of fat in walnut milk.

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-3 As shown, a mixing tank for producing plant protein beverages is disclosed, comprising a tank body 1, a top cover 2 fixed to the top of the tank body 1, a top shell 3 fixed to the middle of the upper surface of the top cover 2, a bushing 4 rotatably connected to the middle of the top cover 2 via a bearing, a stirring assembly 6 passing through the bushing 4, a plurality of wall scraping assemblies 5 fixed to the bottom of the bushing 4 inside the tank body 1, a motor 7 for driving the stirring assembly 6 to rotate fixed to the upper surface of the top shell 3, a linkage assembly 8 installed on the inner side of the top shell 3, the motor 7 driving the bushing 4 to rotate via the linkage assembly 8, a feed pipe 9 and a one-way exhaust valve 12 fixed to the two sides of the top cover 2 respectively, a first one-way valve 91 installed in the middle of the feed pipe 9, an air inlet pipe 11 passing through and fixed to the side wall of the bottom of the tank body 1, a discharge pipe 10 fixed to the middle of the bottom of the tank body 1, and a controller 13 installed on the upper surface of the top cover 2.

[0019] In this embodiment, the controller 13 is a controller with a screen. Specifically, the Siemens SIMATIC KP1200 model can be selected: KP1212 Basic PN (6AV2123-2GB03-0AX0). The controller 13 controls the operation of the motor 7 using existing technology. The specific connection circuit and control method are the same as those of existing technology and will not be described again.

[0020] An electric heating mechanism is installed inside tank 1.

[0021] In this embodiment, the electric heating mechanism adopts the same heating method as the existing mixing tank. A sensor is installed inside the tank 1 to monitor the temperature of the beverage inside in real time. After the temperature information is fed back to the controller 13, the controller 13 controls the operation of the electric heating mechanism in reverse to achieve constant temperature. This method also adopts the same temperature control method as the existing mixing tank.

[0022] The bottom of the tank 1 is cone-shaped, and a valve is installed in the middle of the discharge pipe 10.

[0023] After the beverage is processed inside the tank 1, the valve on the discharge pipe 10 can be opened to allow the beverage to be discharged from the discharge pipe 10 at the bottom of the tank 1. The bottom wall of the tank 1 is designed in a cone shape, which is more conducive to the discharge of the beverage.

[0024] A second one-way valve 111 is fixedly connected to the bottom end of the air inlet pipe 11, and the other end of the air inlet pipe 11 is connected to a nitrogen gas supply machine.

[0025] The nitrogen generator can be started and stopped independently, and there are no restrictions on the model of the nitrogen generator. After starting the nitrogen generator, food-grade nitrogen is injected into the tank 1 through the air inlet pipe 11. The nitrogen not only makes the beverage roll inside the tank 1 and improves the stirring efficiency, but also forces the air inside the tank 1 out through the one-way exhaust valve 12, minimizing the contact between the beverage and oxygen in the air, thereby avoiding the oxidation of plant protein.

[0026] The stirring assembly 6 includes a vertical shaft 61 that passes through the bushing 4 and is rotatably connected to the bushing 4 via a bearing. The top end of the vertical shaft 61 is fixedly connected to the output shaft of the motor 7, and the bottom end of the vertical shaft 61 is fixed with a stirring blade 62.

[0027] Motor 7 is a geared motor, and the specific model can be selected according to actual manufacturing. Motor 7 can directly drive the vertical shaft 61 and the stirring blade 62 to rotate, thereby stirring the beverage inside the tank 1.

[0028] The linkage assembly 8 includes a side shaft 81 rotatably connected to the top wall of the top shell 3. The top and bottom ends of the side shaft 81 are respectively fixedly connected to a second gear 82 and a third gear 83. The output shaft of the motor 7 is fixedly connected to a first gear 71. A fourth gear 41 is fixedly fixed to the surface of the bushing 4. The first gear 71 meshes with the second gear 82, and the size of the first gear 71 is smaller than that of the second gear 82. The third gear 83 meshes with the fourth gear 41, and the size of the third gear 83 is smaller than that of the fourth gear 41.

[0029] The wall scraping assembly 5 includes a crossbar 51 fixed to the outer wall of the bushing 4, and a scraper 52 fixedly connected to the other end of the crossbar 51. The scraper 52 is in contact with the inner wall of the tank body 1.

[0030] Through the transmission of the linkage component 8, the motor 7 can also drive the bushing 4 to rotate, thereby driving the scraper assembly 5 to rotate. Since the size of the first gear 71 is smaller than that of the second gear 82, and the size of the third gear 83 is smaller than that of the fourth gear 41, the multiple gears have a speed reduction effect, causing the scraper assembly 5 to rotate slowly and avoiding severe friction between the scraper 52 and the inner wall of the tank 1. The scraper 52 is made of flexible silicone material.

[0031] Working principle: First, plant protein beverage is added into tank 1 through feed pipe 9. Because feed pipe 9 is equipped with a first one-way valve 91, the inner wall of tank 1 is sealed, and some air is forced out through one-way exhaust valve 12. At this time, controller 13 controls motor 7 and the electric heating mechanism inside tank 1 to operate. Motor 7 drives scraper assembly 5 and stirring assembly 6 to rotate simultaneously, thereby stirring the plant protein beverage. Scraper assembly 5 prevents the plant protein beverage from adhering to the inner wall of tank 1. Simultaneously, the nitrogen generator connected to air inlet pipe 11 is started, introducing food-grade nitrogen into tank 1, expelling the remaining air inside tank 1 through one-way exhaust valve 12, reducing contact between the plant protein beverage and oxygen, and preventing oxidation. After preparation, the valve on discharge pipe 10 is opened to discharge the plant protein beverage.

[0032] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
