APRICOT COMPOTE STERILISATION METHOD Russian patent published in 2018 - IPC A23L3/04 A23L2/42 

FIELD: food industry.

SUBSTANCE: apricot compote sterilization method involves the installation of cans with the product after being rolled into a carrier, preventing the lids from being torn off during the heat treatment. Cans are cooled in the upper row of the first heat treatment zone with water of 40 °C for 6 min. Water can be heated to 58–60 °C and flows down to the banks in the bottom row of the first zone, heating them. Banks are transferred to the second zone, where the cans are cooled in the upper row with water of 60 °C, which heats up to 78–80 °C and drains by heating the cans in the bottom row of the second zone for 6 minutes. Banks are transferred to the third zone, where the cans are cooled in the upper zone by water at a temperature of 80 °C, which heats up to 95–98 °C and flows down by heating the jars in the bottom row of the third zone for 6 min. Cans are transferred to the fourth zone where the heating is carried out by air at a temperature of 150 °C and a speed of 8.0 m/s for 5 minutes. Then the banks enter the upper row of the third zone to continue the heat treatment. Water after heating in the first and second zones is used for cooling in the upper row of second and third zones. Water after heating in the third zone is used to mix and heat water to the required temperature in all cooling zones. During the heat treatment, the cans with the product rotate from the bottom to the lid at a frequency of 0.13 s^-1.

EFFECT: invention provides higher quality of final product.
