METHOD FOR THERMAL PROCESSING OF LIQUID PRODUCTS AND APPARATUS FOR PERFORMING THE SAME

FIELD: food-processing industry, in particular, method and equipment for thermal processing of liquid product. ^ SUBSTANCE: method involves heating product by means of steam which is supplied and immediately mixed with product by spraying said product until product droplets are produced, with diameter of droplets being less than 0.3 mm; heating at heating rate less than 1,100 C/s to temperature which does not cause qualitative changes in product, with pressure changing rate for spraying of liquid product being at least 109 Pa/s, and droplet speed making at least 10 m/s; carrying out heating under low pressure conditions by means of unsaturated steam, which is supplied in the same direction. Apparatus has spraying chamber incorporating sprayer, steam generator, cooling chamber and vacuum pump, and is additionally equipped with steam generator. Spraying chamber is further provided with vacuum controlling unit providing for keeping of pressure at the level of 0.25 Pa. ^ EFFECT: provision for desired level of microbiological stability without changing of organoleptical and physicochemical properties of product. ^ 4 cl, 2 dwg, 3 tbl, 3 ex
