A heat exchanger is a device built for the efficient transfer of heat from one medium to another. Heat exchangers are very much used in the food and beverage industries for heating and cooling products in sterilizing systems, pasteurizers, enzymatic deactivation, etc. They are also used in auxiliary systems such as water heating systems, steam generations, recovery systems, fluid coolers, etc.
MachinePoint Engineering supplies heat exchangers designed especially for the food and beverage industries. They are built in stainless steel type ASI-314, ASI 316, ASTM 449, ASTM 249, Duplex for marine waters. Our heat exchangers have a hygienic design and they are easily cleaned with CIP systems. They are well-known for their innovative designs and exceptional quality. We manufacture both standard units and custom designs to meet the individual requirements of our customers.
Tubular heat exchangers
This is the simpler heat exchanger. It consists of a straight tube with one or more inner plain or corrugated tubes situated on a shell. They are easy to install, modify and readapt in the future.
They are used for treating products with solids, enzymatic deactivation processes, and products with high viscosity of up to 2000 cps. Used for processes such as fruit sterilization, marmalade processing, vegetable cubes sterilization, etc. They are designed for pressures of up to 50 bars.
Shell and Multi tube heat exchangers
They are used for products with viscosity of up to 500 cps and liquids with small solids. Also used for high pressure applications greater than 30 bar.
They consist of a shell with a bundle of tubes inside. One set of tubes contains the liquid to be treated and the other set of tubes are heated or cooled. The tubes diameter is between 6 to 35 mm. The set of tubes might be composed by several types of tubes.
They are used for example in natural juice pasteurization with high fiber content, indirect UHT systems, etc.
Annular heat exchangers
They consist of a triple tube where the product to be treated goes in the tube in the middle and the cooling and heating liquids in the tubes on the sides.
They are used for high viscosity products such as pastes, sauces, or fruit and vegetable concentrates.
An example of their application is for sterilizing tomato concentrate at 30 brix with 200 bar pressure.
MachinePoint Engineering designs and manufacturers different annular heat exchangers with pressures from 20 to 300 bar.
Scraped surface heat exchangers
These heat exchangers are required in crystallization processes, cooling at very low temperatures or heating of products with high viscosity up to 20.000 cps.
MachinePoint Engineering develops and manufacturers different types of scraped surface heat exchangers.
Plate heat exchangers
It is composed of multiple thin, separated plates with large surfaces, so that the liquid phases through them. They are the best option for heating and cooling liquids without pulp such as apple juice, milk, wine, water, etc.
They are fabricated in stainless steel and customized for each customers and product needs.
