Тube Heat Exchangers

“Shell and Tube” Heat Echangers

Suitable for heating of  slightly viscous products such as crashed tomatoes, fruit and vegetable pulps and semi concentrates.

They are build of pipes mounted in tube plates in both ends. The so formed bundle is mounted inside a stainless steel body and is closed with covers at both sides.   There are bafflers in the covers, which are changing the direction of the fluid and determine the number of the strokes.

A steam is fed into the space between the pipe bundle and the body.

“Tube inTube” Heat Exchangers

Consist of concentrically mounted pipes.

To increase the efficiency of the heat transfer a “tube in tube in tube” system is used, especially for more viscous products. Three pipes are concentrically mounted.

 In the inner tube and in the space between the outside and the middle tubes a heating (or cooling) agent is fed.  In the middle space  - between the second and the third pipes the product is passing in a thin layer.

The tube heat exchangers are mounted on own legs or of frame.

They can be completed with steam and condensate valves and pipes etc. and with system for product  temperature regulation as well.

Installations with Tube Heat Exchangers

Thermohran Eng.”designes and manufactures installations with tube heat exchangers as follows:

• Installations for deae-ration and hot filling of juices nectars, puree including baby food. The capacity of installations from 1000 up to  5000 l/h
• Installations for  fillings preparation.Capacity from 1000 up to 3000 l/h.

These installations are applied in the canning industry for preparation and heating of fillings for conservesand juices. The fillings can be clear ( acid or salt  solutions) , sugar solutions, fruit or vegetable  pulps.

All installations are completed with the necessary thermometers, system for temperature regulation and control panel.

Sterilizing Cooling Installations with Tube Heat Exchangers

They are suitable for sterilization and cooling of products with low or medium viscosity such as fruit and vegetable puree and semi concentrates.

The sterilizing section is “shell and tube” heat exchanger. The heating agent is steam with high pressure. The range of heating varies between 105 up to 130 oC depending on the product.

The cooling module is “tube in tube” heat exchanger. In the outer pipe a cooling water is fed, the product is passing in the inner pipe.. The range of cooling is up to 35 oC

For better mixing of product through the pipes, static mixing spirals can be put inside the product pipe.

The installation is able to work either in line for aseptic filling of tanks or in “bag in drum” aseptic filling system.

The capacity varies from 1000 up to 6000 kg/h

They are completed with automation - system for automatic regulation of temperature, registration device, automatic recirculation of product if sterilization temperature is not reached.

Тhe company developed  and designed sterilizing installations “tube in tube in tube”.

Scraped Surface Heat Exchanger

Used for heating and cooling of viscous food liquids. Provide uniform product  heating in the whole volume. Consist of heat exchanger, frame and drive. The body (pos.3) is jacketed cylinder in wich the working fluid is feeded. A rotor (pos.2) with blades (pos.1) is mounted in the cylinder. The blades are mixing and scraping the product. The rotor bears on ball bearings mounted in the two caps (pos.4).
