Description

Technical Field

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

[0002] Vacuum packaging, also known as reduced pressure packaging, is to extract all the air in the packaging container and seal it, maintaining the bag in a highly reduced pressure state. The scarce air is equivalent to the low oxygen effect, which deprives microorganisms of the living conditions, so as to keep the fruit fresh and free from disease and rot. Currently used are vacuum packaging in plastic bags, aluminum foil packaging, glassware, plastic and its composite material packaging, etc. The packaging material can be selected according to the type of item.

[0003] In the prior art, a cover is usually not provided at the upper end of a vacuum packaging device. When the vacuum packaging device is not in use, a large amount of pollutants will enter the interior of the packaging tank, affecting the use effect and service life of the internal components. Some vacuum packaging devices with a cover adopt a flip-top cover, which is often unable to prevent pollutants from contaminating the packaging tank during use, resulting in poor use effect, poor product quality, and little profit. Vegetables generally contain moisture and other substances. When air is extracted, moisture and other substances will enter the interior of the suction pipe, causing the suction pipe to be blocked, affecting normal vacuum packaging, and low packaging efficiency.

[0004] For example, Chinese patent CN208264717U discloses a vacuum packaging device for vegetable processing. A dustproof plate is clamped on the upper end of the packaging groove. When not in use, the packaging groove can be isolated from the outside world, pollutants will not enter the interior of the packaging groove, the internal components will not be damaged, and the service quality and life of the components are improved; elastic parts and fixing parts are provided. When in use, the fixing parts are taken out to pop out the dustproof plate. At this time, packaging work can be carried out, and pollutants will not enter the interior of the packaging groove. The use effect is good, the product quality is high, and the profit is increased.

[0005] However, the device does not have a device for sterilizing and cleaning the packaging tank during use, which causes bacteria in the packaging tank to contaminate the packaged vegetables, affecting product quality.

[0006] For this reason we urgently need to provide a vacuum packaging device for vegetable processing. Utility Model Content

[0012] Preferably, the placement box contains an alcohol solution, and when the brush is located directly above the placement box, the bottom of the brush can extend into the placement box and come into contact with the alcohol. The placement plate and the lower pressure plate are wiped and disinfected by dipping the brush into the alcohol solution in the placement box, thereby preventing the vegetables from being contaminated and improving the quality of vegetable production.

[0013] Preferably, the output end of the vacuum pump is connected to the vacuum packaging device body, and when the cover plate moves down into the vacuum packaging device body, the vacuum pump is started to extract the air inside the vacuum packaging device body, thereby putting the packaging bag in a vacuum state.

[0014] Preferably, the lower pressing plate is located directly below the upper pressing plate. By placing the sealing part of the vegetable packaging bag on the top of the lower pressing plate, when the cover plate moves down into the interior of the vacuum packaging device body, the sealing part is clamped and fixed in cooperation with the upper pressing plate, thereby facilitating vacuum packaging of the vegetables.

[0015] Preferably, limit blocks are fixedly installed on the left and right sides of the top of the cover plate, and the two limit blocks are slidably connected to the left and right sides of the support frame.
