QUINCE COMPOTE STERILIZATION METHOD Russian patent published in 2018 - IPC A23L3/04 A23L2/42 

FIELD: food industry.

SUBSTANCE: quince compote sterilization method involves the installation of cans with the product after being rolled into the carrier, preventing the lids from breaking off during the heat treatment. Jars are cooled in the top row of the first heat treatment zone with water at temperature of 40 °C for 12 min. Water, when the jars are cooled, can be heated to 58–60 °C and it flows down to the jars in the bottom row of the first zone, heating them. Jars are transferred to the second zone, where the jars are cooled in the upper row with the water temperature of 60 °C, which heats up to 78–80 °C and flows down, heating the jars in the bottom row of the second zone for 12 minutes. Jars are transferred to the third zone, where the jars are cooled in the upper zone with water temperature of 80 °C, which is heated to 95–98 °C and flows down, heating the jars in the bottom row of the third zone for 12 minutes. Jars are transferred to the fourth zone where the heating is carried out with air at a temperature of 150 °C and a speed of 8.0 m/s for 20 minutes. Then the jars 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 cover at a frequency of 0.33 s^-1.

EFFECT: invention provides higher quality of final product.
