RU2450568C2 - Cherry compote sterilisation method - Google Patents

Abstract

FIELD: food industry.

SUBSTANCE: invention relates to food industry. Jars filled with compote are put into the carrier ensuring their air-tightness and heated in 70°C water during 3 minutes with subsequent transfer into 85°C water for 5 minutes and then - into 100°C water for 12-15 minutes. Then one performs the jars cooling in 18-20°C air flow at a rate of 3-4 m/s during 5 minutes with further continuation of cooling in an air flow with application of a 65-70°C water film on the jar surface during 8 minutes. During the heat treatment process the jars are turned upside down with a frequency equal to 0.1 s^-1.

EFFECT: invention allows to reduce thermal treatment duration and decrease treatment non-uniformity.

Description

The proposed method for the invention relates to the canning industry and can be used for sterilization of cherry compote in cans 11-68-350.

Sources that were searched for by this method showed that the prototype of the proposed method is a method for sterilizing cherry compote [1], according to which the cans after seaming are installed in a special carrier that provides mechanical tightness of the cans and are heated in water at a temperature of 70 ° C, for 5 minutes, followed by transfer to water at a temperature of 85 ° C for 5 minutes and then to water at a temperature of 100 ° C for 12-15 minutes, after which it is cooled in a stream of air at a speed of 3-4 m / s for 20 min and in the process heat treatment cans rotate from the bottom to the lid with a frequency of 0.1 s ^-1 .

The disadvantages of this method are:

- long duration of the process;

- high consumption of thermal energy.

The aim of the proposed method is to save thermal energy, reducing the duration of the process and thereby improving the quality of the finished product.

This goal is achieved due to the fact that the cans after seaming are installed in a special carrier that provides mechanical tightness of the cans and are preheated in a bath with water at a temperature of 70 ° C for 3 minutes, followed by transfer to a bath with water at a temperature of 85 ° C for 5 minutes and 100 ° C for 12-15 minutes, followed by cooling in a stream of air with a temperature of 18-20 ° C at a speed of 3-4 m / s for 5 minutes and further cooling in a stream of air with application to the surface of the can water film t at a temperature of 65-70 ° C min for 8 min and during the heat treatment, the cans rotate from the bottom to the lid with a frequency of 0.1 s ^-1 .

An example of the method

After sealing, the cans with compote are installed in a carrier that provides mechanical tightness (preventing caps from tearing off during heat treatment) and placed in a hot water bath at 70 ° C for 3 minutes. After 3 minutes, the carrier with the cans is transferred to a bath of water with a temperature of 85 ° C for 5, followed by transfer to a bath of water with a temperature of 100 ° C for 12-15 minutes. After this time, the banks are cooled in the air stream at a temperature of 18-20 ° C at a speed of 3-4 m / s for 5 minutes and then continued cooling in the air stream with a water film at a temperature of 65-70 ° C min during 8 minutes and during the heat treatment, the cans rotate from the bottom to the lid with a frequency of 0.1 s ^-1 .

Salient features of the proposed method are: three-stage heating of compote in water at temperatures of 70, 85 and 100 ° C, respectively, 3, 5 and 12-15 min, followed by cooling in an air stream at a temperature of 18-20 ° C at a speed of 3-4 m / s for 5 and further cooling in the air stream with the application of a water film on the surface of the can with a temperature of 65-70 ° C min for 8 min and during the heat treatment, the cans rotate from the bottom to the lid with a frequency of 0.1 s ^-1 .

The total duration of the sterilization process according to the proposed method is 33-36 minutes, which is 9 minutes less compared to the prototype.

This mode provides a reduction in the duration of the process and thereby improving the quality of finished products, saving heat energy.
