SMOKE PRODUCTION METHOD AND APPARATUS Russian patent published in 2001 - IPC

FIELD: food-processing industry. SUBSTANCE: method involves providing multiple-staged sorption of smoke gas with water at countercurrent and straight flow of contacting media and performing alternate contact of fine-dispersed water particles and flowing water film with smoke gas produced at pyrolysis temperature below 400 C from wood having initial moisture content of 45-70%. Apparatus has housing 1 and transverse internal walls 2 dividing its interior into separate sections arranged in the course of flow of smoke gases. Nozzles 3 and heads 4 are mounted inside housing 1. Smoke gases are initially brought into contact with fine-dispersed water particles in sorption zone (1) first in the course of flow of smoke gases, with following contact of smoke gases with flowing water film in zone adjacent to head 4, with media flowing in straight flow mode. In the second zone (II), smoke gases come into contact with thin water film in head 4, with following contacting with water particles finely dispersed by nozzle 3, with media flowing in countercurrent flow mode. Contacting of smoke gases with water medium in zones III and IV is carried out in the way similar to contacting in zones I and II. Method and apparatus provide for improved contacting of smoke gases with water media and reduced content of hazardous substances in smoke flavoring preparation. EFFECT: increased efficiency and improved quality of smoke meat and fish products. 3 cl, 1 dwg, 2 ex
