Description

Container for canned food.

, 2.

The invention relates to the food industry, namely to the canning industry and can be used in the production of canned food.

Known packaging for a set of food products, including canned food, consisting of lower and upper parts and molded from plastic sheet materials, and food compartments are made in the lower part of the package. The upper and lower parts of the package are hermetically connected to each other, at least along the perimeter of each compartment, by pressing with heat. The upper part is made of two-layer polymer materials, with one layer made of polyethylene and the other made of polyamide. The lower part is also made of two-layer polymer materials, with one layer made of polyvinyl chloride and the other made of polyethylene. (RU 2125009 C1, 01.20.1999, B 65 D 81/32).

Canned cans are known in containers, which, after packing prepared raw materials in containers, are sealed and sterilized (Collection of technological instructions for the production of canned food. T.1, Moscow, Food Industry, 1977, p. 107-130).

Also known are containers for cans, the production of which involves the preparation of components, packaging, evacuation, sealing, sterilization and cooling (RU 2195137 C2, 12.27.2002, A 23L 1/212).

The objective of this utility model is to reduce labor and material costs in the production of containers for canned food for long-term storage, to reduce the cost of canned food, and to improve the quality and organoleptic indicators in the finished product.

and a pressure of from 1200 to 10000 Pa and cooled by showering with cold water with a temperature of from +2 to +6 ° C, the container is made of multilayer, gas-tight, containing sealing and protective layers of the film, molded in the form of a container with a lid, and the container is made of a film with a thickness from 900 to 1500 microns, and the lid is made of a film with a thickness of 200 to 1000 microns, while the lid is hermetically attached to the container by welding.

The multilayer film from which the container and the lid are molded may contain at least three layers made of alternating materials that differ in physical and chemical properties, for example, polypropylene, polyamide and polypropylene, and the layer thicknesses are related as 1 : (0.3 - 1.0): 1.

The lid can be hermetically attached to the vessel by welding for 0.4 - 2.0 seconds with the formation of a seam that is continuous along the vessel’s contour and produces a clear, uniform imprint of the welding element, moreover, welding is performed by the welding element, which creates a temperature from +120 to + + at the place of welding 320 ° С and pressure from 100 kg / m to 3000 kg / m.

The technical result provided by the given set of features is to reduce labor and material costs while increasing the efficiency and manufacturability of the production process through the use of containers made of multilayer films with identified optimal parameters and the use of the identified optimal temperature and pressure modes during autoclaving. The identified optimal parameters and modes can increase the efficiency of sterilization of products during processing in an autoclave, increase the duration of storage while ensuring high quality of stored products, reducing the cost of manufacturing containers and packaging of the product in it.

In this case, the finished product, according to the invention, meets high sanitary and hygienic requirements.

The utility model is illustrated by the following examples, which, however, do not cover and, moreover, do not limit the entire scope of the claims of this utility model.

Example 1

In the production of canned food from poultry meat, a one-hundred-gram capacity is used, formed from a multilayer, gas-tight film containing a sealing and protective layer of film.

The film thickness is 1,500 microns. The film contains three layers, alternating from materials that differ in physical and chemical properties: polypropylene, polyamide and polypropylene. The thicknesses of the layers are correlated as 1: 0.4: 1.

The cover is made of 600 micron film. The thicknesses of the layers are also correlated as 1: 0.4: 1.

The lid is hermetically attached to the container by welding for 0.9 seconds with the formation of a continuous along the contour of the container weld and obtaining a clear uniform print of the welding element. Welding was performed by a welding element that creates a temperature of 200 ° C and a pressure of 1500 kg / m at the welding site.

Then the canned food was autoclaved by heating at a temperature of 150 ° C and a pressure of 4000 Pa for 15 minutes. Cooling of the finished canned food was done by chilling with cold water at a temperature of 4 ° C. In this case, jets of cold water, which, if directed directly to the product to be cooled, could deform the container, were sent to the walls and ceiling and ricocheted created fine dust.

Bacteriological indicators of ready-made canned poultry meat are given in table. 1.

Bacteriological indicators

Name of indicator

The number of mesophilic aerobic and facultative anaerobic microorganisms, CFU in one year

The presence of bacteria, E. coli primers in g of product

The presence of salmonella in 25 g of product

The presence of sulfite-reducing clostridia in 0.01 g of product

The product obtained meets high sanitary and hygienic requirements and retains all its properties for 1 year of storage. The product can be directly heated in a container in a microwave oven.

The implementation of containers in accordance with this technical solution reduced the total cost of canned food production.

Example 2

In the production of canned food from beans with tomato sauce, a three hundred gram capacity is used, formed from a multi-layer, gas-tight, containing; it is sealed; and the protective layers of the film.

Tolsh; ina film is 1200 microns. Nlenka contains three layers, alternating from materials, different; they are physically and chemically related to each other: polypropylene, polyamide and polypropylene. Tolsh; ina layers are correlated as 1: 0.5: 1.
