Description

The proposed method of the invention relates to the canning industry and can be used in the production of blueberry compote in cans 1-82-500.

Sources that were searched by this method showed that the prototype of the proposed method is a method for producing compote with sterilization in an autoclave [1] according to the mode:

$$\frac{\mathrm{twenty}-8-\mathrm{twenty}}{\mathrm{one\; hundred}}\cdot 118\mathrm{to}P\mathrm{but}$$

where 20 is the duration of the period of heating water to 100 ° C, min;

8 - the length of the period of its own sterilization at 100 ° C, min;

20 - the duration of the cooling period, min;

100 - sterilization temperature, ° C;

118 - back pressure in the autoclave, kPa.

The disadvantages of this method are:

- the need to create backpressure in the apparatus during the heat treatment, which requires additional energy consumption;

- the complexity of the technological equipment for thermal sterilization, due to the fact that it operates under excessive pressure;

- a long duration of the technological cycle, which reduces the performance of sterilization equipment and degrades the quality of the finished product.

The technical result of the proposed method is aimed at creating a method for the production of compote, providing increased productivity of sterilization equipment, reducing the duration of the technological cycle, simplifying the process of thermal sterilization and improving the quality and competitiveness of finished products.

, обеспечивающему равенство конечной температуры охлаждения воды в автоклаве ее начальной температуре, требуемой при загрузке очередной партии консервов, с продолжением охлаждения в другой емкости по режиму $$\frac{5}{50-40}$$

:The specified technical result is achieved due to the fact that the fruits packaged in jars are poured with hot water at a temperature of 85 ° C for 2-3 minutes, then they are replaced with syrup at a temperature of 98 ° C, the jars are sealed with self-extinguishing lids [2] and sterilized in open devices without backpressure on the mode $$\frac{\mathrm{fifteen}-8-\mathrm{fifteen}}{70-\mathrm{one\; hundred}-70}$$

ensuring the equality of the final temperature of water cooling in the autoclave to its initial temperature required when loading another batch of canned food, with continued cooling in another tank according to the regime $$\frac{5}{\mathrm{fifty}-40}$$

:

where 15 is the duration of the period of heating water from 70 to 100 ° C, min;

8 - the length of the period of its own sterilization at 100 ° C, min;

15 - the duration of the period of cooling water in an autoclave from 100 to 70 ° C, min;

70 - the initial temperature of the water in the autoclave before loading the next batch of canned food;

100 - sterilization temperature, ° C;

70 - the final temperature of the water in the autoclave at the end of the cooling process;

5 - the duration of the cooling period of canned food in another container at a water temperature of 50 to 40 ° C, min.

An example implementation of the method.

Before the syrup pouring into syrups for 2-3 minutes, pour hot water at a temperature of 85 ° C into the cans for 2-3 minutes, then replace this water with syrup at a temperature of 98 ° C, roll the cans with self-ejecting lids, place in an autoclave with hot water at a temperature of 70 ° C and subject heating for 15 minutes, increasing the temperature of the autoclave to 100 ° C. Then, for 8 minutes, the cans are sterilized at the achieved water temperature of 100 ° C, followed by cooling of the water in the autoclave for 15 minutes to 70 ° C (the initial temperature of the water when loading another batch of canned food for sterilization) and continue cooling in another container at a water temperature of 50 to 40 ° C for 5 min.

Pouring syrup at a temperature of 98 ° C allows you to significantly save thermal energy due to the fact that the syrup is boiled at a temperature of 100 ° C and when canned according to the proposed method, the syrup is cooled to 98 ° C before pouring into cans, and not to 85 ° C, as provided in the technology manual.

The use of self-ejectable lids ensures the removal of air from the cans during their heating, which, firstly, provides the possibility of carrying out the sterilization process without creating back pressure in the apparatus and, secondly, the removal of air from the cans contributes to a more complete preservation of biologically active substances contained in the product, t .to. the lack of air in the banks significantly reduces their decomposition due to the cessation of oxidative reactions.

Cooling canned food in an autoclave to the initial water temperature required when loading another batch of canned food (70 ° C) provides the possibility of reducing the duration of the canned food production cycle and thereby increasing the performance of sterilization equipment, since the time required (8-10 min) is excluded from the process cycle for heating water from 35-40 ° C (final canned cooling temperature according to the existing method) to 70 ° C (initial temperature of the autoclave water before loading another part and canned). And, in addition, the method saves thermal energy (eliminates heat consumption for heating water from 35-40 ° C to 70 ° C) and cooling water (eliminates the consumption of water for cooling water in an autoclave from 70 ° C to 40 ° C).

Salient features of the proposed method are: preheating fruits in jars before pouring syrup with hot water at a temperature of 85 ° C, which allows pouring syrup into a jar at a temperature of 98 ° C (according to current technological instructions, the temperature of the syrup when pouring 80-85 ° C) [1] ; the cans are sealed with self-extinguishing lids and the heat treatment is carried out without creating back pressure in the apparatus; the canned food in the autoclave is cooled to a water temperature equal to the initial water temperature when loading another batch of canned food for sterilization.

This mode provides a reduction in the duration of the technological cycle, an increase in the productivity of sterilization equipment, energy savings due to the unnecessary creation of back pressure in the apparatus, does not require sophisticated technological equipment for the thermal sterilization of canned food, saving heat energy and improving the quality of finished products by removing air from cans and reducing the duration of heat treatment.
