Description

The invention relates to storage vessels for perishable products of vessels supplied with refrigerators or external side coolers placed inside them. The proposed can is intended for the storage and transportation of milk and other perishable products subjected to sterilization during the extraction of air and at the same time artificial cooling. The can is a prismatic shaped vessel with a throat with cylindrical refrigerators installed in the angular sinuses and a nipple placed on the lid of the throat.

In FIG. 1 shows a side view of a can; FIG. 2 - its top view; FIG. 3 is a section along the line AISDS in FIG. 2

The material for the vessel 1 prismatic shape (Fig. 1, 2 and 3) with refrigerators placed at the corners is tinplate or galvanized iron. The body and the bottom of the can make one, and the walls 2 and the bottom 3 should be angular, able to press or bulge. On top of the vessel is closed by a removable bottom 4 with flanges 5, and rubber gaskets are used for tight closing. The bottom 4 has a neck 6, closed with a cone-shaped lid 7 with a nipple 8 for connecting the can to the air extraction device. The lid 7 is also mounted on a rubber gasket, but sometimes, both the upper bottom 4 and the lid 7 are soldered to the vessel 1. Removable upper bottom 4 is used when the vessel is intended to be filled with solid products. Four chambers 9 are placed inside the vessel at its corners by soldering the corners to the entire height of the vessel, into which cylinders of porous clay are inserted, filled with some kind of cooling mixture (sodium hydroxide with hydrochloric acid or dilute nitric acid, etc.) g The chambers 9 are closed with a plug. They are covered with lids 10 having openings. In order to protect vessel I during transportation from damage and from the influence of the outside air temperature, the vessel is covered with felt, straw, etc., and is inserted into the wooden wrap.

For storage or transportation, milk and liquid are poured through the neck of the can, and solid products are placed in the can, for which the top bottom is removed. Then by pump: the air is pumped out of the can, as a result of which the bottom and sides of the can are pressed and pressed against the liquid so that there is no empty space inside, which is necessary for transportation, as it protects, for example, milk from churning. Dry products should be poured with sawdust, straw, etc. After pumping out air, if desired, carbon dioxide is admitted through a special nipple, and cooling mixtures are poured into the porous cylinders in chambers 9.

The subject matter of the invention.

1. A canister for storing and transporting milk and other perishable products, prismatic in shape and with a throat, characterized by replacing in its angular sinuses cylindrical refrigerators 9 of porous mass, filled with a cooling mixture. a nipple 8 for pumping out air or admitting carbon dioxide (Fig. 1-3).

2. With the use of a removable top bottom as specified in item 1 for filling with solid material.
