Abstract

The invention allows a more uniform cooling of the viscous product over its entire mass. A bundle of heat exchanging tubes 4 forming autonomous sections 5 is placed inside the casing with the inlet pipes 1 and outlet 2 of the product. The tubes of each section are evenly spaced between the axes of the pipes of the adjacent section. Between sections 5 there is a device for mixing the product, made in the form of two plates with holes of conical shape, in contact with each other from the bottom of the cones and adjacent to the ends of the pipes 4 adjacent sections 5. The holes of each plate are coaxial with the pipes 4 of the corresponding section 5 and have a smaller diameter equal to the internal diameter of the pipes 4. At the junction of sections 5, when the heat exchanger is operating, the product flow is divided into separate parts and mixed with the parts of the flow coming out of other pipes 4. 3 Il.

Description

The invention relates to heat exchangers and can be used in the food industry.

The aim of the invention is to more uniformly cool the product throughout its mass.

FIG. 1 shows a heat exchanger; in fig. 2 section A-A in FIG. one;

in fig. 3 section bb in fig. 2

The heat exchanger contains skin.x with nozzles for inlet 1 and outlet 2 of the product and nozzles 3 for the cooling medium. Inside the casing, a bundle of heat exchange tubes 4 forming autonomous sections 5 is located. The axes of the pipes 4 of each section 5 are evenly located between the axes of the pipes 4 of the adjacent section 5. Between sections 5 there is a device for mixing the product, made in the form of two plates with holes of conical shape in contact with each other from the base of the cones and adjacent 4 pipe ends adjacent sections 5. The holes of each plate are coaxial with the pipes 4 of the corresponding section 5 and have a smaller diameter equal to the internal diameter of the pipes 4.

The heat exchanger operates as follows.

The viscous product enters the nozzle 1, fills it and goes further into the pipes 4 of the first section 5, where the product is heat exchanged with a cooling medium washing the pipes 4 outside. At the junction of the first and second sections 5, the product stream passing through one pipe 4 is divided into several equal parts by means of perforated plates. In this case, each pipe 4 of the second section 5 receives equal to 0

The following parts of the product flow from several adjacent pipes 4 of the first section 5. In the following sections 5, a similar process of dividing the flow of each pipe 4 into parts and mixing them with parts of the flow coming from the other pipes 4 of the same section 5 occurs. The finished product is discharged from the heat exchanger through pipe 2.

The use of the invention provides intensive movement of the viscous product between sections 5 or more and its uniform cooling across the entire mass. In addition, the size and weight of the heat exchanger, as well as energy consumption during its operation, are reduced.
