Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of food packaging equipment, and specifically relates to a food aseptic heat packaging device. Background Technology
[0002] Food packaging is an important component of food products. It not only protects food from biological, chemical, and physical damage, but also maintains stable food quality, facilitates consumption, and attracts consumers through its design. Food packaging technologies include various methods such as moisture-proofing, vacuum packaging, gas filling, shrink packaging, modified atmosphere packaging, canning, and aseptic packaging.
[0003] Aseptic packaging is a technology that packages sterilized food in a sterile environment, aiming to keep food fresh and safe for an extended period without the addition of preservatives or refrigeration. This packaging technology typically involves the use of specific aseptic packaging materials, such as metal cans, glass bottles, plastic containers, composite cans, paper-based composites, and multi-layered flexible packaging. The key to aseptic packaging is ensuring the sterility of the packaging materials, the product, the environment, and the seal, as well as performing filling and sealing under sterile conditions.
[0004] However, currently, aseptic packaging of food usually involves placing sterilized food in a sealed bag and then vacuum-sealing the bag. In this process, not only is it easy for food to be contaminated with bacteria during transfer, but the sealed bag cannot be sterilized, which may lead to food contamination by bacteria. Utility Model Content
[0005] To address the aforementioned problems, the purpose of this invention is to provide a food aseptic heat packaging device that can simultaneously sterilize the food to be packaged and the packaging film, and can then perform subsequent heat sealing.
[0006] The technical solution of this utility model is: a food aseptic heat packaging device, comprising:
[0007] The casing has a packaging platform at its bottom.
[0008] The first film is attached to the upper surface of the packaging table for placing the food to be packaged.
[0009] The second film is movably positioned above the packaging platform via a lifting assembly;
[0010] A heating sterilization assembly is disposed on the inner side wall of the housing and is used to heat and sterilize the packaged food and to sterilize the opposite sides of the first film and the second film.
[0011] A vacuum sealing device includes a hot press frame connected to the top of the housing via a lifting rod and a vacuum pump disposed inside the housing. A vertical groove is provided on one side of the hot press frame, and a lifting hot press head is slidably disposed in the vertical groove. A telescopic rod is vertically fixed on the outer side of the lifting hot press head. A connecting pipe is provided at the far end of the telescopic rod, and a suction pipe parallel to the telescopic rod is provided at the lower end of the connecting pipe. The suction pipe is connected to the vacuum pump via the connecting pipe.
[0012] Furthermore, the packaging platform is provided with a first roller and a first motor connected to the first roller on both sides. The first motor is used to drive the first roller to rotate, and the two ends of the first film are respectively wound around the first roller.
[0013] Furthermore, the lifting assembly includes:
[0014] Two lifting seats, one of which is located on the outer side of each of the first rollers;
[0015] The second roller is provided at the upper end of each of the lifting seats, and the two ends of the second film are respectively wound around the second roller;
[0016] The second motor is fixedly mounted on the lifting base and is connected to the second roller to drive the second roller to rotate.
[0017] Furthermore, the heating sterilization assembly includes an infrared heater and an ultraviolet sterilization lamp uniformly disposed on the inner sidewall of the housing.
[0018] Furthermore, the connecting pipe and the vacuum pump connection section are flexible connecting pipes.
[0019] Furthermore, a cutting component is movably embedded in the upper surface of the packaging platform, the cutting component comprising:
[0020] A cutting groove is embedded in the upper surface of the packaging table and corresponds to the shape of the hot press frame;
[0021] The cutting blade is movably embedded within the cutting groove;
[0022] A hydraulic lifting rod is installed inside the packaging table, and the cutting blade is installed at the upper end of the hydraulic lifting rod.
[0023] Furthermore, the housing has a movable door on its side.
[0024] The working method of this utility model is as follows: A first motor drives a first roller to rotate, thereby winding a first film between two first rollers and adhering it to the surface of the packaging table. A second motor drives a second roller to rotate, thereby winding a second film between two second rollers and aligning the second film with the first film. Then, a lifting seat raises the second film, creating a certain distance between the second and first films. The food to be packaged is then placed on the first film of the packaging table. The movable door is closed, and the heating sterilization assembly is activated to sterilize the food to be packaged and the opposite sides of the first and second films. During the sterilization process, the true The air pump is turned on to a lower setting to draw out the gas generated by heating inside the shell. After sterilization, the lifting rod drives the hot press frame to descend. At this time, the suction end of the suction tube is located at the lower end of the vertical groove. The hot press frame heat-seales the first and second films around the food to be packaged, except for the suction tube. The vacuum pump evacuates the space between the first and second films through the suction tube. After evacuation, the telescopic rod extends, causing the suction tube to detach from the space between the first and second films. At the same time, the lifting hot press head descends to heat-seal the hole left after the suction tube is removed. Finally, the hydraulic lifting rod drives the cutting blade to rise and cut off the excess film next to the heat-sealed area.
[0025] Compared with existing technologies, the advantages of this invention are as follows: This invention provides a food aseptic heat packaging device. By setting a first film and a second film spaced apart on the packaging platform, and sterilizing the food to be packaged, the first film, and the second film using a heating sterilization component located within the housing, bacteria on the films are prevented from affecting the food. A vacuum pump is also included, which can extract steam and other gases generated during heating and sterilization. Furthermore, when the heat-sealing frame seals the first and second films, a suction tube extracts the gas between the films, placing the food in a vacuum packaging state. In summary, this invention has the advantages of novel structure, convenient use, and good sterilization effect. Attached Figure Description

[0038] The heating sterilization component 4 is disposed on the inner wall of the housing 1 and is used to heat and sterilize the food to be packaged, and to sterilize the opposite side of the first film 2 and the second film 3.
