PLANT FOR STORAGE OF AGRICULTURAL PRODUCTS Russian patent published in 1995 - IPC

FIELD: refrigerating engineering. SUBSTANCE: chamber 1 is charged with agricultural product using batcher 15 controlled by control system 18, and optimal temperature 19, moisture 20 and carbon oxide concentration 1 are maintained. Apparatuses are interposed between the first 4 and second 5 compressor stages of a cooling machine. The apparatuses are used for condensation gas in cooler 6 and separating water in water separator 7 after compressing gas mixture in the first stage 4. Carbon oxide is condensed in vortex pipe 8 and separated in cyclone 10. Fresh air is added to cold air which flows from gas-expansion machine 3 through air intake 16, water is added through a pipe line for draining water from moisture separator 7, and gas is added through control valve 17 inside batcher 15. Regenerator 13 and ejector 11 return a part of used energy to coolant of the cooling machine. EFFECT: enhanced preservation of agricultural product. 1 dwg
