DEVICE FOR STORAGE OF IMPAIRED PRODUCTS Russian patent published in 2019 - IPC F24F13/06 A01F25/08 

FIELD: food industry.

SUBSTANCE: invention relates to the field of food industry, in particular to engineering equipment of public and industrial buildings, and can be used in warehouses isolated from the external environment and storages of deteriorating and decaying products. Device of room for storage of impaired products includes enclosures from walls, ceiling and floor coatings, recirculation ventilation system, having openings in windows of supply and intake of gas medium filling, respectively, equipped with prechambers and chimneys with guide inserts, main sections in the form of equidistant parallel sleeves with shutoff valves, drive gas pressure plants connected to prechambers and chimneys of branch pipes with distribution grids accordingly inlet and outlet of gas medium, made of metal sheet with holes, diameter d_hol=1–3 mm, having symmetry axis, and installed in at least two consecutive rows of dynamic gas head levelling equalizers, as well as gas medium regeneration system with component filtration units, surface electric heaters and surface coolers, purification-feed and measuring and control systems. At that, dynamic pressure levelers are assembled into detachable installed in openings cassettes, and holes in plates of aligners are made in staggered order with uniform between their axes pitch b=(2.5–4.5) d_hol, inter-sheet distance δ=(1.5–3.5) d_hol, where d_hol is diameter of holes, m, and axes of holes of next sheet are offset relative to axes of holes of previous sheet by S=0.5b, m, with diameter reduction to d_hol1=K⋅d_hol, where K=(0.6–0.9) is a decreasing coefficient. Components of component filtration are arranged in sleeves of main sections of gas ducts, surface electric heaters and surface coolers are built in components of component filtration, cleaning-feeder complex is equipped with own sleeves for selection and make-up of gas components with shutoff-control valves and suction-discharge equipment connected to sleeves of main sections of gas ducts.

EFFECT: invention increases degree of levelling of dynamic pressure of gas medium inside ventilated room with minimization of number and size of non-current circulation zones.
