Embodiment 1

[0009] Carry out vacuum packaging on raw grain.

[0010] First build a fully enclosed granary with a sealable door, install a one-way valve on the wall of the granary, install temperature sensors, humidity sensors, pressure sensors, and cooling equipment in the granary. After storing raw grain in the granary, close the door of the granary, connect the vacuum pump to the one-way valve for vacuuming, and monitor the pressure sensor until the pressure of the granary reaches the requirement. The temperature sensor, humidity sensor and pressure sensor are monitored in real time. When the temperature in the granary rises, the cooling equipment is started to cool down; when the humidity or pressure in the granary increases, the granary is vacuumed again.

[0011] The preservation and storage of raw grains is a problem all over the world. Because the traditional vacuum packaging method cannot vacuum pack raw grains, the preservation and storage of raw grains is often carried out by in...

Embodiment 2

[0013] Vacuum packaging of finished grain.

[0014] Existing finished grain packaging is generally packed in fiber woven bags, such as: rice is packed in plastic fiber woven bags, and noodles and miscellaneous grains are packed in cotton fiber woven bags. The disadvantages of this type of packaging are: the outside of the packaging is stained with rice and flour dust, which is unhygienic; the packaging bag is breathable and moisture-permeable, and the rice and noodles are prone to insects and mildew, and the shelf life is very short. The method of the present invention is used to vacuum-pack the finished grain, the packaging bag is made of PVC material, the opening of the packaging bag is made into a sealable bag opening, a one-way valve is arranged on the packaging bag, the finished grain is packed into the packaging bag, and the mouth of the bag is sealed. Seal, then, connect the vacuum pump to the one-way valve for vacuuming. When the food packed in this way is bought by p...

Embodiment 3

[0016] Vacuum pack live fish.

[0017] Put the sterilized live fish into a flexible packaging bag equipped with a one-way valve, and fill the packaging bag with an appropriate amount of water mixed with nutrient solution, then seal the opening of the packaging bag, and then connect the vacuum pump to the Apply vacuum to the one-way valve. The traditional vacuum packaging method cannot vacuum-pack the living body, but the vacuum packaging method of the present invention can be used to vacuum-pack the living body, which greatly prolongs the survival time of the living body during transportation and reduces the probability of infection of the living body during transportation , and reduces the transportation space, reduces the transportation cost.

Abstract

The invention relates to a reverse direction exhaust vacuum packing method and a usage thereof. The packing method comprises: a sealed packing body at a loading hole of a sealable packaged object is provided with one or more exhaust nozzle(s) which can be check valve(s) or sealable exhaust nozzle(s); the packaged object is put into the packing body from the loading hole of the packaged object, and the loading hole of the packaged object is sealed, so that the packing body becomes a closed packing body; evacuating equipment can be connected on the exhaust nozzle(s) for air suction until the air pressure in the packing body reaches the requirement of vacuum packing. The method can be used for food packing, tea packing, textile packing, harmful object packing, raw grain packing, grain finished product packing or living body packing. The invention has the advantages that vacuum package can be made at will, the packing body can be vacuumized for a plurality of times according to the change of air pressure in the packing body, and the application scope of the vacuum package can be greatly expanded. The method for manufacturing the vacuum package is simple, convenient and flexible, and can be used for air change type near vacuum packing for living body.

Description

Technical field: [0001] The invention relates to a reverse exhaust vacuum packaging method and its application. Background technique: [0002] For a long time, the production of vacuum packaging has been completed on a specific assembly line and special equipment. The vacuum packaging method is the forward exhaust vacuum packaging method. The process flow is "exhaust first, then seal". The loading port is exactly the exhaust port of the packaging body. This vacuum packaging method determines that the vacuum packaging can only be vacuumed once, and the vacuum package cannot be vacuumed multiple times. Its poor flexibility and maneuverability, large limitations, and high vacuum packaging cost make this vacuum packaging technology unable to be widely used. Invention content: [0003] The purpose of the present invention is to provide a vacuum packaging method that can be made and used at will, is not limited by the site and equipment, has a wide range of applications, and c...
