METHOD AND APPARATUS FOR PRODUCTION OF A LOW DENSITY WAFER PRODUCT Russian patent published in 2017 - IPC A21D13/00 

FIELD: food industry.

SUBSTANCE: invention relates to the production of wafers, and more particularly to a method for aerating the batter to maintain an aerated structure of wafers during their production. Disclosed is a method for production of wafers, which comprises the following steps: (i) providing a batter mix comprising at least flour and water; (ii) subjecting the batter mix to aeration treatment, wherein aerating comprises wherein the aeration treatment involves preparation of a primary foam followed by injection of the foam into the batter mix to produce the batter mix; (iii) optional subjecting the aerated batter mix to mixing; (iv) feeding the mixed and aerated batter mix to a heated baking surface through a batter depositor; and (v) baking the mixed and aerated batter mix to obtain a wafer, wherein the aeration treatment in step (ii) is down-stream along the process flow from any direct pumping of the method, with the help of a lobe pump or impeller pump, or progressive cavity pump, or diaphragm pump, or peristaltic pump, or gear pump. Apparatus for making wafers, as well as produced wafers are also proposed.

EFFECT: invention allows to produce a product having a lower effective density of at most 0,16 g/cm³, and with sufficient strength to be able to remove them from the wafer baking plates.
