METHOD FOR DRYING GELATIN BROTH IN THE PRODUCTION OF DRY GELATIN Russian patent published in 2021 - IPC C09H9/02 A23J1/10 A23J3/06 A23L3/54 

FIELD: food industry.

SUBSTANCE: gelatin broth is evaporated to a concentration of dry substances of C=14-24%. The broth is foamed, it is applied to a work surface and blown with air with relative humidity of W=50-60%. The broth is dried at atmospheric pressure in a gelatinized state in the form of rods of square or rectangular cross-section with cross-section sides h₁=2-4 mm or in the form of a layer with the thickness of h₂=2-4 mm. The air temperature during drying does not exceed the gelatinization temperature and the air flow velocity v=4-5 m/s, where the air flow direction is parallel to rods. At the same time, the broth is dried under bilateral infrared irradiation of rods with the density of heat flux falling from one side of the rod of E=0.95-2.45 kW/m², which begins after a period of time t=0.03-0.15 h after the start of the drying process of the foamed broth.

EFFECT: invention makes it possible to increase the specific intake of dry gelatin (0.136-0.807 kg/(m²·h)).
