Description

A continuous sterilizer for cans with cans is known, made in the form of an airtight container divided into U-shaped compartments with heated liquid through which a conveyor with carriers for cans passes.

In the described sterilizer, in comparison with the known one, the possibility of breaking the covers from glass jars with canned food under the influence of internal pressure was eliminated. For this purpose, the carriers for the cans are made in the form of semicircular troughs, divided by partitions into compartments for each individual can, provided with bellows abutting the covers of the cans.

To achieve the required temperature without increasing the pressure in the sterilizer, glycerol was used as the heating medium.

FIG. 1 shows a sterilizer circuit; pas figs. 2 is a carrier diagram for cans with cans.

The sterilizer is a rectangular metal reservoir /, which is divided into compartments of 2, 3, 4, 5, 6, 7 8 V-shaped.

Through the chambers are mixed, the conveyor I on which the carriers 10 for cans P with canned food are hinged. When the conveyor is moving, cans of canned food are always in a horizontal position.

The can carriers 10 are semicircular troughs 12 divided by partitions 13 into compartments, each of which contains sylphs 14, presses a jar lid, thereby preventing the lid from the can from breaking the pressure inside the jar during sterilization. In the case of bo cans during the sterilization process (for one reason or another), the carriers remove broken jars with the product from the sterilizer, without clogging it.

In compartments 2 and 3, the filling water is heated by steam entering through spargers 15. In compartment 4 filled with glycerin, the latter is heated with steam 8-10 atm passing through heating tubular surfaces 16. Compartment 5 is a thermostat, the air in which is also heated by steam of 8-10 atm, passing inside the ribbed tubular heating surface 17.

Through pipe 18, cold water is supplied to compartment 8, from which water passes through circulation pipes 19, 20 and 21, respectively, to compartments 7, 5 and t3. In each zone of the sterilizer, thermostats are installed to maintain the set temperature.

In order to save heat, reuse of hot water is foreseen. The water, heated by passing cans in compartment 6, is supplied to heat the cans in compartment 3. Before the sterilizer is started, the required temperature in each zone is first created in it.

In the compartment 2 cans of canned food are heated in water to 60 °, in compartment 3 to 98-99 °, in compartment 4 - to {with glycerin) up to 120 °. In compartment 5, the temperature is maintained at a level of 120 °.

After compartment 5, banks are cooled: in compartment 6 with water to 100 °, in compartment 7 with water up to 60 ° and in compartment 8 also with water up to 40 °.

Claims (2)

1. A continuous sterilizer for cans with cans, made in the form of an airtight container divided into V-shaped compartments with heated liquid through which a conveyor with can carriers passes, characterized in that in order to prevent disruption from glass lids cans under the influence of internal pressure; carriers for cans are made in the form of semicircular troughs, divided by partitions into compartments for each individual can, fitted with bellows abutted against the can flaps. 2. In the sterilizer according to claim 1, use glycerol as a heating medium in order to achieve the required temperature without an increase in pressure. ° oh "Oj h one.
