SUGAR COOKIE PREPARATION METHOD Russian patent published in 2013 - IPC A21D13/08 A21D8/02 

FIELD: food industry.

SUBSTANCE: invention relates to food industry. The method envisages preparation of the components recipe mixture in a mixer, the mixture consisting of strained egg melange or egg powder, invert syrup and malt extract. After the components stirring during 2-3 one introduces into the mixture food salt, sugar sand, a dry milk product and sodium bicarbonate; the mixture is stirred for 8-10 minutes; then one introduces into the mixture a preliminarily liquefied fat component, supplies lecithin and additionally stirs the mixture at continuous recirculation of the recipe mixture along the pipeline (where hydrodynamic cavitation conditions are ensured) by means of the pump. Then the recipe mixture is treated in a cavitation installation with a ultrasonic converter installed inside a water-jacketed pipeline under the conditions of combined acoustic and hydrodynamic cavitation within mutually perpendicular planes by way of recirculation by means of a pump via the cavitation installation pipe reactor with two-stage change of the gap formed between the reactor inner wall and the a ultrasonic converter surface. Then the emulsion is delivered into a kneading machine with Z-shaped blades, the working tool rotation frequency equal to 15-30 rpm, and is mixed with a flavouring agent, an ammonium carbon salt and the remaining fat component quantity; after stirring during 4-5 minutes one supplies a mixture of powdery components consisting of wheat flour, starch and recyclable wastes at the operating stroke of the kneading machine; the dough is kneaded during 8-15 minutes till uniform distribution of the components in an amount of 90-92% of the total weight; then dough pieces are moulded of dough with moisture content equal to 15-16.5% and density equal to 1150-1250 kg/m³, baked and cooled.

EFFECT: invention enables elaboration of a progressive emulsion preparation technology, improve the ready products quality indicators, intensify separate process operations and the process flow as a whole.
