Description

Technical Field

[0001] The utility model relates to the technical field of food packaging equipment, in particular to a packaging device for food processing. Background Art

[0002] Food processing refers to the process of treating raw food ingredients through a series of processing techniques and technologies to change their physical, chemical and microbiological properties, extend the shelf life of food, improve taste, increase nutritional value and increase food diversity. Food processing includes steps such as cleaning, cutting, pickling, cooking, freezing and baking, aiming to ensure the safety and quality of food. After processing, food will be transported to various distributors for sale. In order to ensure that the food still has good quality when it is sold, food processing plants usually use vacuum packaging. In a vacuum environment, the oxygen content in the food is greatly reduced, thereby slowing down the rate of oxidation reaction, delaying the deterioration of food, and allowing the food to remain fresh for a longer time. Secondly, vacuum packaging can also prevent food from spoiling and corruption. Since vacuum packaging reduces the oxygen content in the air, the growth and reproduction rate of microorganisms are inhibited, thereby reducing the possibility of food being contaminated by bacteria and mold. In addition, vacuum packaging can also maintain the taste and nutrition of food. Since vacuum packaging can effectively prevent oxidation reactions and the growth of microorganisms, the texture, taste and nutritional components of food can be maintained, allowing consumers to enjoy better taste and nutrition when eating. Therefore, the application of vacuum packaging equipment in the food processing process not only helps to extend the shelf life of food and reduce the risk of food spoilage and corruption, but also can maintain the taste and nutrition of food and improve the quality and sustainability of food.

[0003] To this end, the utility model patent with publication number CN213292816U discloses a food vacuum packaging device for food processing, including a packaging box, a first installation box and a bottom pad, the first installation box is fixedly installed in the middle of the lower surface of the bottom pad, a vacuum pump is fixedly installed inside the first installation box, one end of the vacuum pump is fixedly connected to an air pipe, one end of the air pipe is fixedly connected to a connecting pipe, the connecting pipe is located inside the bottom pad and passes through the upper and lower surfaces of the bottom pad, the packaging box is fixedly installed on the upper surface of the bottom pad, the connecting pipe is connected to the bottom of the packaging box, and the second installation box is fixedly installed on the upper surface of the packaging box. The device can filter out internal impurities during vacuuming by installing a filter net to prevent impurities from entering the packaging box and contaminating the food. In addition, the device is also provided with an ultraviolet sterilization lamp to disinfect and sterilize the food inside the box, thereby increasing the safety of the equipment.

[0004] However, this patent requires that the entire packaging box be vacuumed before the sealed door is opened to take out the food. However, after the vacuum is drawn, the packaging box is in a negative pressure state, and it is difficult to open the sealed door under atmospheric pressure. In actual use, it is troublesome to open the sealed door, which affects the packaging efficiency. Utility Model Content

[0005] The utility model aims to provide a food processing packaging device to solve the above-mentioned deficiencies in the prior art, which can effectively prevent negative pressure from affecting the reinforcement efficiency.

[0007] Preferably, the fixing device includes a fixed card block, which is fixedly installed in the vacuum chamber, a movable card block is provided on one side of the fixed card block, a slide groove is opened on one side of the movable card block, a connecting block is slidably arranged in the slide groove, one end of the connecting block is fixedly connected to the movable card block, and the other end is fixedly connected to a cross bar, a threaded hole is opened in the middle of the cross bar, a threaded column is threadedly connected in the threaded hole, one end of the threaded column is fixedly connected to the inner wall of the box, and the other end is fixedly connected to the motor, and the stator part of the motor is fixedly connected to the inner wall of the box.

[0008] Preferably, the sealing device includes a cylinder, which is fixedly mounted on the top inner wall of the vacuum chamber, a telescopic end is fixedly mounted on one side of the cylinder, a heating block is fixedly mounted on the bottom of the telescopic end, a pad is provided under the heating block, and the pad is fixedly mounted on the bottom of the inner wall of the vacuum chamber.

[0009] Preferably, an indicator sign is provided in the vacuum chamber.

[0010] Preferably, universal wheels are fixedly mounted on the bottom of the supporting legs.

[0011] Preferably, a lock is provided inside the protective door.

[0012] The utility model is simple and convenient to use. It only requires placing the food packaging bag to be vacuumed in the vacuum chamber according to the indicator sign, and then starting the motor. The rotation of the motor drives the threaded column to rotate, and then drives the cross bar to move, so that the connecting block drives the movable clamping block to move, and then the movable clamping block pushes the food packaging bag to move and make it contact with the fixed clamping block to complete the fixation. Then, the opening of the food packaging bag is aligned with the straw and the vacuum pump is started to vacuum it. After the extraction is completed, the cylinder is started, and the cylinder pushes the heating block to squeeze the food packaging bag and then heat it, so that the food packaging bag melts and then is sealed. After the sealing is completed, the motor is started to reverse and the food packaging bag can be taken out to complete the packaging.

[0013] Compared with the prior art, the beneficial effect of the utility model is that after the food packaging bag is restricted by a fixing device, a straw is inserted into the food packaging bag for vacuuming, which can reduce the scope of vacuuming, save resources, and avoid the formation of a large negative pressure space that affects subsequent packaging. The universal wheels also facilitate the movement of the device, thereby improving the convenience of the device. BRIEF DESCRIPTION OF THE DRAWINGS
