METHOD FOR PRODUCING OF FRIED COFFEE PRODUCTS Russian patent published in 2005 - IPC

FIELD: food-concentrates industry, in particular, method used in processing lines for processing of coffee products, preferably, chicory and coffee beans.

SUBSTANCE: method involves preparing raw material; providing thermal treatment with overheated steam and intermediate moistening of raw material; before thermal treatment, providing preliminary two-staged heating of product within conductive heating chamber: first stage including treatment with used air to temperature of 45-50 C, and second stage including treatment with used overheated steam to temperature of 55-65 C; drying product for one day within drying chamber with air to temperature of 85-95 C; discharging used overheated steam having temperature of 130-140 C into heat-exchanging recuperator for heating air to temperature of 110-120 C, followed by feeding thereof for preliminary heating of product at the second stage; discharging vapors of moisture evaporated from product into condensate accumulating container, from which said vapors are partly directed for intermediate moistening of product in frying chamber and partly into steam generator; heating produced steam in steam superheater and directing to frying chamber in closed cycle mode; discharging 8-10% of non-condensed gases from overheater steam recirculation contour and directing used air having temperature of 90-100 C from drying chamber into heat-exchanging recuperator and further for preliminary heating of product at first stage and directing to drier and further to drying chamber in closed cycle mode.

EFFECT: reduced consumption of power for frying process, improved quality of ready product and provision for creating ecologically safe conditions for producing of fried coffee products.
