Description

The proposal relates to the packaging industry, in particular to the packaging of products or materials in special conditions of the gas environment by introducing gas into the container using nozzles.

Food spoilage is caused by the development of microorganisms and the oxidation of product components. A prerequisite for both processes is the presence of molecular oxygen. One of the methods for protecting products from microbial and oxidative damage is their storage in a modified gas environment.

In a modified gas environment, the air inside the package is replaced by a mixture of inert gases (usually nitrogen and carbon dioxide), which excludes or slows down the process of oxidation (spoilage) of food. Low oxygen levels prevent the development and reproduction of fungi, bacteria and other microorganisms.

The use of a modified gas environment is a natural and environmentally friendly technology for preserving the product and increasing its shelf life; it is used by many food industry enterprises.

This is the most modern way to preserve the quality and freshness of food products, allows you to increase the shelf life by several times without freezing, and also eliminate the use of chemical additives and preservatives. The essence of packaging in a modified gas environment is to replace atmospheric air with a mixture of gases, which inhibits the growth of microorganisms. The gases that make up atmospheric air - nitrogen, oxygen and carbon dioxide, are used in the required proportions to produce a gas mixture in which fresh food is stored.

After changing the composition of the medium inside the container, to maintain the constancy of its composition, it is necessary to ensure the tightness of the closed container for gases, liquids, and other elements of the external environment.

Thus, the necessary technological processes for ensuring the storage of the product in a mixture of gases of a given composition are the displacement of atmospheric air from the container with the product, filling it with gas, the subsequent hermetic closure of the container.

A prior art device is known for packing cotton candy products (patent No. RU 2165149 dated July 3, 2000, according to claim 8) containing a frame on which a device for welding the edges of the shells of a thermoplastic film is mounted and a device for sealing the packaging and input air to create excess pressure, including a needle-duct, while the device for welding the edges of the shells includes a ring table with an elastic gasket and two diametrically located brackets, on the bottom of which is a spring-loaded traverse hinged, supporting a gimbal-type heater and equipped with a handle with a groove for interacting with the hook axis located on the other bracket, and an electromagnet kinematically connected to the traverse handle in its closed position, while the device for introducing air the package and its sealing contains an annular table with a wire electrode fixed to it, a control unit for air supply through the needle-duct, and a control unit for the sealing process, contains a housing with a button for turning on the electrode and a clip spring-loaded to the handle and equipped with an elastic element for pressing the package to the electrode, the needle-duct, clip and handle pivotally mounted on the housing on one axis, and a two-arm lever pivotally attached to the housing to provide kinematic connection of the handle and buttons for turning on the electrode.
