Description

The invention relates to food industry and agriculture.

Known containers, containers for storing agricultural products (Aut. St. No. 1130249, 676226, 895386), which allow to increase the shelf life while improving the storage quality of products; they usually contain a hermetic container, a gas-selective membrane, inlet and outlet valves.

The main disadvantage of these devices is that the regulated gas environment in them is created by supplying gas from pressurized cylinders, which are Filled in a separate industrial unit.

Closest to the proposed is the capacity for autosw. No. 1414353, consisting of a sealed housing, inlet and outlet valves, a gas-selective membrane, a perforated chamber for the adsorbent.

This capacity improves the quality of storage. by creating the necessary gas medium. However, to fill the tank with the necessary gas, additional cylinders are needed, which require special safety measures, periodic inspection in boiler inspection bodies, and have large weight and size characteristics.

The aim of the invention is to reduce the overall dimensions of the container and ensure the autonomy of its use. This goal is achieved in that the container comprising a housing with a sealed door, inlet and outlet valves, a gas selective membrane, a perforated chamber with adsorbent located inside the container, is additionally equipped with a gas generator, including a gas generating checker consisting of solid compounds releasing a nitrogen-based gas composition during chemical reactions; the gas generator may have a housing generating a checker, a filter, a heat exchanger, an ignition unit; the inlet valve should be placed in the bottom of the container and connected to the gas generator.

Long-term research in the field of storage of agricultural products allowed us to establish the influence of storage factors with various parameters and their combinations on the degree of damage to the fruit by diseases and to develop models for optimizing conditions

storage, therefore, to determine the variety of fruits, you can select the necessary generating composition of the checkers according to the recommendations. The invention significantly simplifies the method of obtaining the necessary gaseous medium, reduces the overall dimensions and gives autonomy of use.

The drawing shows the proposed container.

The container has a housing 1 with a sealed door 2 for loading and unloading products, an inlet valve 3 for supplying

a tank of gas composition and an outlet valve 4 for outputting ehb residues and for taking samples during operation. The container is also equipped with a gas-selective element (membrane) 5, protected from external

exposure to a metal grill to maintain gas exchange of the product with the external environment. Adsorbent 6 is installed inside the container (perforated chamber with alumina, vermiculite and

etc.), which allows, depending on its properties, to provide moisture control and absorption of ethylene-forming components. In order to obtain the required amount of gas, a container is connected

a gas generator, which consists of a generating checker 7, a filter 8 for gas purification, a heat exchanger 9 and an ignition unit 10 from an autonomous source.

Into a container through a sealed

fresh agricultural products are laying the door. Next, a gas generator is connected to the container through the inlet valve 3. When igniting the generating rod 7, the resulting gas passes

through the filter and enters the heat exchanger 9. Then the cooled gas enters the container through the inlet valve 3 located in the bottom of the container. Excess gas during product processing is vented to the atmosphere through outlet valve 4. Upon completion of processing, the gas composition required for storage in the container (98% N2, 2% 02, 2-4% COa) is maintained using a gas selective membrane. To verify such a composition, gas samples can be taken through an outlet valve, thereby establishing the need for re-injection of gas.

Weight and size characteristics

the proposed container is 50-60% less than the prototype.
