RU73310U1 - GAS-EXCHANGE DEVICE FOR STORAGE OF PLANT PRODUCTS IN SEALED TANKS - Google Patents

Abstract

The utility model relates to the food industry and can be used to store food plant products in the warehouses of wholesale bases and individual stores. Technical result achieved:

- improving the efficiency of the gas exchange device,

- increasing the working area of the gas-selective membrane without increasing the size of the gas exchange device. The essence of the utility model is as follows: The gas exchange device for storing plant products in sealed containers contains a housing (1) with an opening (2), a perforated cover (3) fixed to it, and a gas-selective membrane located between them (4). In the housing (1), an annular abatement (5) is made with protrusions located on its surface with rounded peaks (6), on which a gas-selective membrane (4) rests. In this case, the height of the protrusions with rounded peaks (6) is equal to the depth of the annular collapse (5).

Description

The utility model relates to the food industry and can be used to store food plant products in the warehouses of wholesale bases and individual stores.

A gas exchange device is known for storing plant products in sealed containers, containing a perforated body, a perforated lid fixed on it and a gas selective membrane located between them, see USSR author's certificate for invention No. 1018892 class V65D 39/04, published on 05/23/1983 in the Bulletin No. 19. In it, the membrane is made of a hydrophobic polymer ultrafiltration film, and the housing is designed for connection with a glass jar, which leads to a small storage volume of products.

Also known is a gas exchange device for storing plant products in sealed containers, comprising a housing with a hole, a perforated lid fixed on it and a gas-selective membrane located between them, see the Russian Federation patent for utility model “44638, class B65B 39/04, published March 27, 2005 years in bulletin No. 9. In it, the housing has a tubular wedge-shaped fastening element with an annular protrusion on its outer surface, and the lid has annular protrusions on the lower surface, pressing the membrane to the housing.

The disadvantage of this gas exchange device is the following:

- low efficiency of the gas exchange device

- small working area of the gas selective membrane.

In this utility model, the task is to create such a gas exchange device, which would determine:

- increasing the efficiency of the gas exchange device

- increasing the working area of the gas-selective membrane without increasing the size of the gas exchange device.

The solution to this problem is provided due to the fact that in the gas exchange device for storing plant products in sealed containers, containing a housing with a hole, a perforated lid fixed to it, and a gas-selective membrane located between them, the housing has an annular abatement with protrusions located on its surface with rounded the peaks on which the gas-selective membrane rests, while the height of the protrusions with rounded peaks is equal to the depth of the annihilation of the annular deposition.

The utility model is illustrated using the attached drawing. Figure 1 of the drawing shows a General view of the gas exchange device.

The utility model device is as follows:

A gas exchange device for storing plant products in sealed containers contains a housing (1) with an opening (2), a perforated cover (3) fixed to it, and a gas-selective membrane (4) located between them. The casing (1) has an annular lowering (5) with protrusions located on its surface with rounded peaks (6), on which a gas-selective membrane (4) rests. In this case, the height of the protrusions with rounded peaks (6) is equal to the depth of the annular collapse (5). The protrusions (6) can be made in the form of cones or cylinders with rounded vertices.

When operating a gas exchange device connected to a container for storing plant products, an additional working area of the gas selective membrane is used located above the annular lowering (5) between the protrusions with rounded peaks (6), which increases the efficiency of the gas exchange device.

The applicant made prototypes of the proposed gas exchange device, tests of which confirmed its advantages over known analogues.

Claims (1)

A gas exchange device for storing plant products in sealed containers, comprising a housing with an aperture, a perforated lid fixed thereon, and a gas-selective membrane located between them, characterized in that the housing has an annular contraction with protrusions located on its surface with fastened peaks on which the gas-selective rests the membrane, while the height of the protrusions with rounded peaks is equal to the depth of the annular lowering.
