Description

The invention relates to apparatus for heating and pasteurizing milk and cream with a heating tank in the form of a water tube boiler. In the proposed apparatus for sequential heating of portions of processed dairy products, two pipe systems are used for the designated product, located one above the other in mutually perpendicular directions and associated with receiving and connecting channels.

In FIG. 1 shows a vertical section, along the line AB in FIG. 2; FIG. 2 - horizontal section of the apparatus.

Pedestal 1 (Fig. 1), which simultaneously serves as a blower, has a vertical water-tube boiler with a combustion chamber 4, an grate 3, hot-water pipes 9 and a combustion door 6. It is supplied with a pipeline 8 for power supply and a drain valve 7 for discharging water. For the purpose of sequential heating of portions of processed dairy products, two systems 11 and 12 pipes were used to heat the product, located one above the other perpendicularly in the upper part of the steam boiler and connected to the receiving chambers 13 and 26: first - for wok, second -dl milk. Cream

enter the apparatus through the valve 14 into the receiving chamber 13, from where they pass through the first series of pipes 11 to the receiving chamber 15, and from there to the second series of pipes 11, which go into the receiving chamber 24, where pasteurized cream is collected. The lid 17 of the chamber 15 is fixed by means of clamping screws 18 and upon completion of the operation of the apparatus can be removed to clean the tubes 11. Milk enters the apparatus through a tap 2b into the receiving chamber 26, from where it passes through the first series of tubes 12 into the chamber 29, and from there in the second series of tubes 12, leaving into the receiving chamber 27, which serves to collect preheated and pasteurized milk. To protect the pipes 11 and 12 from damage that may occur when the upper part of the boiler is removed, to clean the hot-water pipes 9, a ring 31 is provided, fixed in the space between the pipes and rigidly connected by rods 31 to the walls of the boiler. The cover 30 of the chamber 29 is arranged similarly with the spike 17 of the chamber 15.

The subject matter of the invention.

A device for heating and pasteurizing milk and cream, with a heating tube in the form of a water tube

boiler, characterized by the use for successively heating portions of processed dairy products of two pipe systems 11 and 12, for heating the product, located one above the

the other is perpendicular to the upper part of the steam boiler and connected to the ends with the receiving and collecting chambers 13, 26 and 24, 27 and with the connecting chambers 15 and 29.
