SUBSTANCE: apparatus for cold treatment of products with carbon dioxide recirculation comprises an insulated housing, horizontal cooling pipes, atomisers mounted around the periphery of the apparatus and connected to each other by a liquid cryogenic agent feeding pipe, a cylindrical perforated grille which forms a hollow cylinder. The pipe is connected to a collector for feeding coolant, which is connected to the horizontal cooling pipes. At the centre of the chamber there is an axial vacuum collector with a vacuum pump connected thereto. The apparatus is provided with a collector for outlet of carbon dioxide for recirculation, for which a cascade cooling apparatus is provided.

EFFECT: high efficiency of the apparatus owing to higher intensity of heat exchange.

SUBSTANCE: device designed for keeping the preset temperature of cooled food products has a storage container for food products and a cooling module filled with a cooling agent, which is connected to the cavity made at least in one wall of the container. The wall has through holes on its side directed inward the container and meant for the cooling agent passage inside the container and which connects its cavity to internal space of the container. Storage container for food products is divided into chambers with the wall to the cavity of which the cooling module is connected and which has holes on both sides for the cooling agent to enter the chambers of the food product storage container.

EFFECT: maximum uniform distribution of cold in the food product storage container.

FIELD: refrigerated processing of food products using carbon dioxide.

SUBSTANCE: apparatus has throttle washer with T-shaped passageway and device for feeding of snow-like CO2 into carcass. Snow-like carbon dioxide feeding device is connected through pipe to liquid carbon dioxide feeding pipeline and comprises plates adapted to be automatically opened for further insertion into carcass. Valve is mounted on pipeline and is adapted to be opened simultaneously with opening of plates.

EFFECT: increased amount of snow-like carbon dioxide upon throttling and reduced coolant losses due to effective distribution coolant within interior of bird's carcass.

SUBSTANCE: plant for obtaining cooling units includes a set of at least two cells, each of which is capable of containing and retaining a cover subject to filling; a feed pipe connected in its upstream part to a liquid CO2 source, and a set of at least two injection tubes. Each injection tube is located opposite the cell in which there will be located the cover subject to filling and connected in its upstream part to the feed pipe. Each injection tube includes an injection hole in at least one place along its length. End of each injection tube, which is opposite to the feed pipe, takes the shape of the embedded end in the form of an essentially rounded tip. Each injection hole of the injection tube takes the shape of a threaded hole of specified diameter D, into which there can be screwed in an injection nozzle. The plant includes at least two injection nozzles, each of which takes the shape of a cylindrical element on at least some part of its length, a hollow cylinder, the outside threaded diameter of which is equal to diameter D, at least of one of the threaded holes, at least of one of the injection tubes and the inside diameter d of which is less than D.
