METHOD FOR FOOD LIQUID DISINFECTION AND INSTALLATION FOR METHOD IMPLEMENTATION Russian patent published in 2015 - IPC A23L3/15 

FIELD: food industry.

SUBSTANCE: food liquid disinfection method involves food liquid treatment with excessive pressure with subsequent depressurisation to atmospheric value; food liquid treatment with excessive pressure is performed in a sprayed state with liquid particles size equal to no more than 100 mcm. Food liquid treatment with excessive pressure is performed by way of liquid recirculation with subsequent depressurisation to atmospheric value in three stages; at the first one the excessive pressure is 2-3 atm, at the second - 4-5 atm, at the third - 6-7 atm; the treatment duration at each stage is 5-10 minutes. The food liquid disinfection installation consists of a device for liquid treatment with excessive pressure which is represented by an airtight vessel equipped with a safety drain valve. On the upper part outside, the airtight vessel is equipped with an air delivery nipple connected (through a controllable valve and an air purification bio-filter and by means of a pipe-line) to the compressor, a solenoid valve for excessive pressure release and a manometer; inwardly, the upper part of the airtight vessel is equipped with a baffle hood; under the latter a jet, ensuring liquid spraying till particles are sized no more than 100 mcm, is installed, connected (by means of the pipe-line) to the pump supplying untreated liquid from the accumulation vessel into the airtight vessel for treatment; outwardly, the lower part of the airtight vessel is equipped with a nipple, connected (by means of the pipe-line) to the pump supplying liquid into the airtight vessel and ensuring liquid recirculation, and with a disinfected fool liquid drainage nipple connected (through the valve and by means of the pipe-line) to a receptacle vessel for food liquid disinfection.

EFFECT: invention allows to achieve a high level of disinfection and food liquid treatment duration reduction 2-3 times.
