PEAR AND QUINCE COMPOTE STERILISATION METHOD Russian patent published in 2012 - IPC A23L3/04 

FIELD: food industry.

SUBSTANCE: jars filled with compote are sealed and put into the carrier ensuring mechanical air-tightness. Then one performs the jars heating in a heated 120°C air flow at a rate of 2.5-3 m/s during 28 minutes. Then the jars are heated by way of showering with a 100°C hot water during 17 minutes with subsequent staged cooling in baths with 80°C water during 5 minutes, with 60°C water during 5 minutes and with 40°C water during 7 minutes. During the whole heat treatment process the jars are turned upside down with a frequency equal to 0.166 s^-1.

EFFECT: prevention of thermal breakage of jars, simplification of the sterilisation process and the apparatus design.
