Description

Technical Field

[0001] The utility model relates to vacuum extraction equipment, in particular to a continuous food vacuum extraction device. Background Art

[0002] Some foods (such as konjac and meatballs) need to remove bubbles during processing. Vacuuming food to remove bubbles can make the inside of the food more uniform and reduce the uneven texture caused by the presence of bubbles, thereby improving the overall quality and shelf life of the food. For liquid or semi-liquid foods (such as sauces, olive oil, sauces, etc.), removing bubbles can make the product more delicate and smoother, improving the consumer's eating experience; bubbles often contain oxygen, which is an important participant in food oxidation reactions. By removing bubbles by vacuuming, the direct contact between oxygen and food can be reduced, thereby slowing down the oxidation rate of food and extending the shelf life; the vacuum environment can inhibit the growth and reproduction of aerobic microorganisms, because these microorganisms are difficult to survive in an environment without oxygen; therefore, vacuum packaging with bubbles removed can reduce the risk of microbial contamination and further extend the shelf life of food; during storage and transportation, if the bubbles in the package expand due to heat, it may cause the package to rupture or deform. Removing bubbles can avoid this and improve the stability of the product; for certain foods with high shape requirements, removing bubbles can help maintain the original shape of the product and prevent deformation or collapse caused by bubbles. Therefore, in actual production, appropriate vacuum packaging technology and equipment should be selected according to food types and processing requirements.

[0003] At present, vacuum extraction mainly adopts table-type vacuum extraction equipment, that is, a vacuum chamber that can be raised and lowered is set on the table. However, the two sides of the vacuum chamber of this equipment are driven by cylinders of different paths to lift and lower, resulting in asynchronous lifting and lowering of the two sides and the front and back of the vacuum chamber. The mold on the table is generally a silicone plate or a stainless steel mold with a product model cavity on the surface, which easily causes the vacuum chamber to be not airtight around the silicone plate on the table, affecting the vacuum effect and product quality. In addition, workers are required to constantly take out and put in the products, which makes the vacuum extraction process discontinuous and is not conducive to improving production efficiency. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a continuous food vacuum extraction device.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a continuous food vacuum extraction device, comprising a conveyor belt and a lifting vacuum chamber arranged at one end of the conveyor belt, the four corners of the lifting vacuum chamber are respectively driven to rise and fall by a lifting cylinder, the cylinder air pipe of each lifting cylinder is respectively connected to a diversion tank, and one end of the diversion tank is connected to the cylinder control air path through a main pipe.

[0006] Furthermore, the conveyor belt and each lifting cylinder are respectively fixed on the top of the frame, and the diversion tank is located in the frame.

[0007] Furthermore, a vacuum pump for lifting and evacuating the vacuum chamber is provided at the bottom of the frame.

[0008] Furthermore, the four sides of the frame are covered with protective baffles.

[0009] Furthermore, the vacuum pump and the diversion tank are fixed on the crossbar at the bottom of the frame.

[0010] Furthermore, the roller shaft at one end of the conveyor belt is driven to rotate by an RV reduction motor.

[0011] Furthermore, support plates are respectively fixed to the frames on both sides of the upper part of the conveyor belt.

[0012] Through the above arrangement, when the utility model is working, the plate-shaped silicone mold is placed on the feeding end of the conveyor belt, and the product raw materials are injected into the molding cavity on the surface of the silicone mold, and the conveyor belt drives the silicone mold to move to the bottom of the lifting vacuum chamber. The lifting vacuum chamber descends under the drive of the four-path lifting cylinders. The mold is located in the vacuum chamber and is evacuated by an internal or external vacuum pump, so that the product raw materials in the molding cavity are evacuated, and the bubbles in the raw materials are extracted, so that the texture of the product after forming is more uniform, thereby improving the overall quality and shelf life of the food, and can make the product more delicate and smoother in taste.

[0013] After the silicone mold is evacuated, the lifting vacuum chamber is lifted and sent out from the other end of the conveyor belt, and can be sent to sterilization, packaging and other processes, realizing continuous vacuum processing of the product and greatly improving production efficiency. In addition, the cylinder air pipes of the lifting cylinders at the four corners of the lifting vacuum chamber are respectively connected to the diversion tank, and one end of the diversion tank is connected to the cylinder control air path through the main pipe, so that the air pressure of the four lifting cylinders at the diversion tank is balanced, thereby forming a stable and synchronous lifting structure at each corner of the lifting vacuum chamber, which is beneficial to the full and close contact between the edge of the vacuum chamber and the work surface after the lifting vacuum chamber falls, and the sealing effect is better, which helps to vacuum and remove bubbles, thereby improving the quality of the product.
