At a very early stage, the edible oil industry discovered the great advantages
of plate heat exchangers and has employed them in many different process
steps. SIGMA plate heat exchangers are employed with particularly high
temperatures in this case,
up to approx. 220°C.
Specially developed, asbestos-free, compressed fiber gaskets ensure long-term
process safety in these high-temperature applications. For
applications in the medium-temperature range, specially developed soft-lip
gaskets are available, which can also be supplied in the adhesive-free
fixing design.
With our product, all applications in the edible oil industry
sector can therefore be covered. Our customers in this sector have
relied on SIGMA heat exchangers for decades.

Typical areas of application of SIGMA plate heat exchangers in the prduction
process of edible oil are:
- Cooling and heating of edible oil
- Cooling of fatty acids
- Heat recovery in the refining process
- Winterizing of edible oil
Application example: EDIBLE OIL
Pressed edible oil, from various fruits and crops, such as olives
or sunflowers, is heated in tanks for neutralization and cleaning,
as well as remove various odor-causing materials. Over
different stages, the oil achieves the level of purity which is finally
provided to the end user in the supermarket. In order to store the
pure oil again in tanks, it must be cooled down to normal temperature.
This cooling comes about through our SIGMA plate heat exchanger,
using an especially mild handling process and taking up very little
space. A continuous cooling capacity is guaranteed by the parallel
circuit arrangement of several units in this case. |
