TUNNEL FOR BACTERICIDAL TREATMENT OF SERIES PORTIONS OF MEAT PRODUCT Russian patent published in 2005 - IPC

FIELD: equipment for spraying of liquid preparation, in particular, trisodium phosphate solution for bactericidal treatment of meat product portions, in particular, carcasses of newly slaughtered bird.

SUBSTANCE: tunnel for bactericidal treatment of portions of meat product has apparatus for spraying of liquid preparation. Said apparatus has tubular nozzle open at both ends, vessel for solution, supply pipeline for connecting vessel with lower part of nozzle, and pipeline for compressed carrier gas, in particular, compressed air, said pipeline being incised into nozzle in the vicinity of liquid supply pipeline. At least one nozzle is not oriented directly to portions of meat product. Liquid preparation is discharged from each nozzle in the form of fog with diameter of droplets mainly of 0.005 mm. Small sizes of droplets allow risk of disturbing continuity of bird's skin upon collision with aerosol spray to be eliminated. Also, bird's skin is not subjected to thermal processing. Tunnel of such construction allows ecological problems connected with difficulty of catching phosphor-containing sewage to be decided in accordance with official rigidified norms.

EFFECT: increased efficiency by eliminating the possibility of obstructing tunnel owing to small sizes of droplets and improved quality of treatment of bird's carcass.
