FIELD: food industry.SUBSTANCE: jars filled with compote are sealed, put into the carrier ensuring mechanical air-tightness and subjected to staged heating in a 120°C air flow at a rate of 1,5 -2 m/s and in a 150°C air flow at a rate of 8-8.5 m/s during 10 minutes Then one proceeds with maintenance at a temperature of 105°C during 5 minutes and cooling in an atmospheric air flow at a rate of 7-8 m/sec during 5 minutes Further cooling is performed in an atmospheric air flow with alternate application of a 65-70°C water film on the jar surface during 7 minutes The jar is turned upside down with a frequency equal to 0.133 s.EFFECT: invention ensures enhancement of the product quality and the heat-transfer process efficiency, simplification of the implementation process and the apparatus design. |
