Abstract

Use: for heating or cooling food. The inventive rotor 7 is located inside the housing 1, which receives rotation through a V-belt drive 8 from the electric motor 9. Easily removable knives 11 are mounted on the brackets 10 of the rotor 7 and the radial flow turbulators T2 are fixed. When the rotor 7 rotates, the coolant is supplied to the jacket 4 through the nozzle 5, and the product is delivered through the tangentially installed nozzle 2, counterclockwise to the rotation of the rotor 7. The tangential introduction of the product into the heat exchanger housing prevents the product from rotating together with the rotor and allows intensively turbulent flow at the bottom of the case. 3 ill. in I

Description

The invention relates to the food industry, in particular to heat exchangers.

The purpose of the invention is the intensification of the heat transfer process.

In FIG. 1 shows the proposed heat exchanger with radial flow turbulators, a longitudinal section; in FIG. 2 is an embodiment of a heat exchanger with axial turbulators; in FIG. 3 is a section AA in FIG. 1.

The heat exchange device consists of a housing 1 with a tangentially mounted nozzle 2 for supplying the processed product and a nozzle 3 for removing the product, a jacket for the heat carrier 4 with nozzles 5 and b for its supply and removal. A rotor 7 is located inside the housing 1, which receives rotation through a V-belt drive 8 from the electric motor 9. Easily removable knives 11 are installed on the brackets 10 of the rotor 7. The heat exchanger is also equipped with radial 12 and (or) axial 13 flow turbulators.

The heat exchange device operates as follows.

With a rotating rotor 7, the coolant is fed into the jacket through the nozzle 5, and the product is transferred to the heat exchanger through the tangentially installed nozzle 2, opposite the rotation of the rotor 7. The tangential introduction of the product into the housing of the heat exchanger prevents the product from rotating together with the rotor and allows intensively turbulizing the flow into bottom of the case.

Rising from the bottom up, the product heats up (or cools), while the knives 11 repeatedly clean the heat exchange surface, constantly exchanging layers

product near the walls of the housing 1 of the heat exchange device. However, in the radial direction, the knives 11 do not provide turbulence for all product layers, because only the wall layer is turbulized.

In this design of the heat exchange device, radial and (or) axial flow turbulators installed in the Zone between the rotor 7 and the knives 11 are provided

12 and 13, which intensively mix all layers of the product with each other. One or another design of flow turbulators or their combination is selected depending on the size of the heat exchanger and

physical characteristics of the heated (or cooled) product.

The product is discharged from the heat exchanger through the pipe 3.

Using the device will allow for

due to intensive turbulization of the product volume, increase the heat transfer coefficient from the wall to the product and between the product layers and thus intensify the heat transfer process by 15 ... 20%.
