Embodiment 1

[0011] Embodiment 1—Carry out ventilation type quasi-vacuum storage to raw grain.

[0012] The preservation and storage of raw grains is a problem all over the world. Since the traditional vacuum method cannot vacuum store raw grains, the value-preserving storage of raw grains is generally stored by increasing the ventilation of the granary. If the storage is not good, it is very susceptible to moisture, insects, and mildew. The resulting losses are enormous. In the humid areas of our country, the shelf life of raw grain is shorter. It is slightly better in the northern region, but the water loss of the raw grain in the north is very serious. Generally, a batch of raw grains will lose at least 4-8 percentage points from storage to delivery. Each grain depot must store at least hundreds of thousands of tons of raw grain, and if the loss of 5% is calculated, tens of thousands of tons will be evaporated. Calculated at 0.8 yuan per catty, the direct loss is more than 16 milli...

Embodiment 2

[0014] Embodiment 2-carry out vacuum packaging to finished grain.

[0015] Most of the packaging of today's finished grains is packaged in traditional woven bags. Because of its air permeability, it is easy to cause large dust, damp, insects and mildew on the packaging surface. Excessive volatilization and drying will lead to the loss of nutrients. There are also vacuum packaging on the market, which can avoid the above problems. However, when the consumer buys it home and opens the package, the vacuum effect is immediately lost. The rest of the food can only be stored naturally, which has the same nature as the woven bag packaging.

[0016] After the finished grains packaged by the method of the invention are opened and used by consumers, the remaining products can be conveniently made into vacuum packaging. Extend the shelf life by more than 1-2 times. There is no need to worry about insects, damp and mold, and it can ensure that the nutrients will not be lost.

Embodiment 3

[0017] Embodiment 3-to tea and food packaging.

[0018] Most of today's tea packaging is stored in natural air-permeable packaging. Due to uncontrollable factors such as moisture and oxidation, the quality of tea leaves changes, so it is old tea after the lunar calendar year. Vacuum packaging is also used in the market, but when the tea packaging is opened, the remaining products can only be stored naturally.

[0019] By adopting the method of the invention to pack the tea leaves, the tea leaves can be taken and vacuumed at will, and the quality of the tea leaves can be guaranteed for a long time. The concept of old tea is postponed for more than one or two years. The present invention can also be used for taking, using and vacuuming in various food packages. It can also be used in refrigerator food storage isolation bags, etc., to completely solve the problem of refrigerator odor and pollution.

Abstract

The invention relates to a packaging method for a vacuum package which can be repeatedly manufactured and used, which is characterized in that a sealing packaged article outlet is arranged on a packaging body with a sealing packaged article inlet, a self-sealing unidirectional exhausting nozzle or a check valve is arranged on the outlet or the packaging body, when the packaged article is packaged in the packaging body through the inlet, the inlet is sealed; gas in the packaging body is pumped by connecting a portable vacuum pump with the unidirectional exhausting nozzle or the check valve, thereby manufacturing vacuum package. The present invention can repeatedly manufacture or use the vacuum package, can randomly adjust pressure according to requirement of packaging body, greatly develops application range of the vacuum package, is simple, convenient and flexible, fully increases recycling value of package, reduces pollution, saves more than half of package amount, improves the package quality more than double, and can be reclaimed for other use.

Description

technical field [0001] The invention relates to a packaging method for vacuum packaging that can be replicated for use, and belongs to the field of vacuum packaging. Background technique [0002] The vacuum packaging on the market today is all disposable vacuum packaging. This kind of packaging must be produced under a specific production environment and equipment, which greatly limits the scope of use of vacuum packaging, and the production cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a packaging method for vacuum packaging that can be replicated for use. The vacuum packaging made by the method of the present invention is simple, convenient and flexible. The reuse value of the packaging body can be fully improved and the pollution to the environment can be reduced. [0004] The purpose of the present invention is achieved in the following manner: [0005] The packaging method of the present invention is as follows:...
