Description

Technical Field

[0001] This utility model relates to the field of dairy processing technology, and in particular to an additive mixing and stirring device for dairy processing. Background Technology

[0002] In dairy product production, various additives are often added and thoroughly mixed. Chinese Patent CN209696719U discloses a mixing and stirring device for dairy product processing, including a placement rack, a mixing tank, a control panel, a top cover, and a rotary motor. The mixing tank is threaded to the top of the placement rack. The control panel is fixedly mounted on the surface of the mixing tank. The top cover is placed on top of the mixing tank, and the rotary motor is welded to the center of the top cover. A return block is fixedly installed inside the placement rack at the top. An electrically controlled valve is fixedly installed at the bottom of the mixing tank. A stirring shaft is vertically positioned below the rotary motor. A filling port is welded through the surface of the top cover. A protective sleeve covers the outer periphery of the stirring shaft. The return block prevents dairy products from entering the gap between the top cover and the mixing tank and causing bacterial growth when the raw materials rise and are stirred inside the mixing tank. It allows the raw materials to flow back to the center of the mixing tank, improving mixing efficiency. This device is suitable for the production and use of mixing and stirring equipment in dairy product processing and has good development prospects.

[0003] The aforementioned patent lacks a cooling function during use. During stirring, the dairy products gradually heat up, and if not cooled in time, some nutrients in the dairy products will be destroyed. Furthermore, the patent lacks a degassing function; during stirring, a lot of air mixes into the dairy products, forming bubbles and affecting the quality after stirring. Therefore, in view of the above situation, there is an urgent need to develop a dairy processing additive mixing and stirring device that is convenient for stirring and mixing dairy products, can cool them during stirring to prevent excessive heating and spoilage, has a bubble-eliminating function, and improves the quality of the stirred dairy products, in order to overcome the shortcomings of current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide an additive mixing and stirring device for dairy processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mixing and stirring device for dairy processing additives includes a mixing tank, a mixing mechanism, a cooling mechanism, and a bubble elimination mechanism. The mixing mechanism extending into the mixing tank is mounted on its top. A cooling mechanism extending into the mixing tank is located on one side of the mixing tank. The cooling mechanism includes a spiral tube, a water tank, a water pump, a semiconductor cooling chip, and heat dissipation fins. The spiral tube is installed inside the mixing tank. The inlet of the water pump is connected to the water tank, and the outlet of the water pump is connected to the lower end of the spiral tube via a pipe. The upper end of the spiral tube is connected to the water tank via a pipe. The water storage tank is filled with water, and multiple semiconductor cooling chips are installed on the side of the water storage tank. The hot end of the semiconductor cooling chip is equipped with heat dissipation fins. A bubble elimination mechanism is installed on the top of the mixing tank and communicates with it. The mixing and stirring mechanism includes: a stirring shaft, a synchronous pulley, a synchronous belt, and a drive mechanism. Three stirring shafts are evenly distributed on the mixing tank. The stirring shafts are rotatably connected to the mixing tank. Each stirring shaft is fixed with a synchronous pulley. The three synchronous pulleys are connected by a synchronous belt drive. A drive mechanism for driving the stirring shafts to rotate is installed on the mixing tank.

[0007] Preferably, both the heat dissipation fins and the spiral tube are made of copper.

[0008] Preferably, the driving mechanism includes a motor, a first gear, and a second gear. The motor is fixed to the top of the mixing tank, the first gear is fixed on the output shaft of the motor, and a second gear meshing with the first gear is provided on one side of the first gear. The second gear is fixed on the stirring shaft.

[0009] Preferably, the bubble elimination mechanism includes a vacuum pump, a conduit, and a pressure sensor. The vacuum pump and the pressure sensor are both installed on the top of the mixing chamber. The suction end of the vacuum pump is fitted with a conduit that is inserted into the mixing chamber, and the detection head of the pressure sensor is inserted into the mixing chamber.

[0010] Preferably, the mixing chamber has a feed inlet at the top, a plug is detachably installed on the feed inlet by means of threads, and a discharge port is provided at the bottom of the mixing chamber, with a valve installed on the discharge port.

[0011] The beneficial effects of this utility model are as follows: When using this additive mixing and stirring device for dairy processing, dairy products and additives are added to the mixing chamber. A motor drives the first and second gears to rotate, which in turn drives the stirring shaft. The stirring shaft mixes the dairy products and additives. Simultaneously, a semiconductor cooling chip cools the water in the storage tank, and a water pump delivers the cold water to the spiral tube. The spiral tube absorbs the heat generated during mixing, thus preventing overheating of the dairy products. After mixing, a vacuum pump is activated to evacuate the mixing chamber to a vacuum state, allowing air bubbles in the dairy products to escape, thereby ensuring the quality of the dairy products. In summary, this utility model facilitates the mixing of dairy products, allows for cooling during mixing to prevent excessive heating and spoilage, and has the function of eliminating air bubbles, thus improving the quality of the mixed dairy products.
