Modernization of a production line and replacement of the heat exchanger intended for the cooling of ketchup
A company involved in the design, manufacture and installation of equipment for the pharmaceutical and food industries has contacted SACOME to request assistance in the supply of a heat exchange system. Their client wants to address the modernization of their production line and, among other improvements, they want to replace the heat exchanger intended for the cooling of ketchup and expand its capacity.
Currently, they use a scraped surface heat exchanger that, since its start-up, does not meet expectations; the required cooling temperature is not reached, and the costs and maintenance times are higher than expected. Knowing the strong economic investment of this type of heat exchange system, and in the face of dissatisfaction with the current operation, the client wants to analyze alternative options to scratched surface heat exchangers.
In close collaboration with the installation company, SACOME analyzes the current problem and studies in detail the rheological characteristics of the product; it is a ketchup sauce with a clear Non-Newtonian behaviour, having high content of seeds and dissolved grains.
Based on its extensive expertise in the cooling of sauces, the technical department of SACOME proposes an annular space heat exchanger. In particular, our model S-TF40A-D with axial product inlet and fully removable tubes.
After acquiring this tubular heat exchanger, the client confirms that the desired cooling temperature is now reached and is very satisfied with the technical advice received.

The importance of rheology in the design of any processing plant is crucial since the sizing of many of the elements composing it is very dependent on this “resistance”, also taking special relevance with food products: heat exchangers, pipes, valves, pumps, mixers, etc.
To design a heat exchanger it is necessary to have certain data, such as the process flow rate, the temperature and the physical properties of products.
Hairpin heat exchangers have a more efficient and economical design compared to a multiple pass heat exchanger when the process requires a temperature crossing between the cold and hot fluid.
