Oil & Fats Refining - Neutralizing

Crude oils are neutralized either by physical or chemical means:

In the first case the fatty acids are steam stripped, whereas in the second case they are converted into soap with caustic soda.

Alkali neutralizing

C.M. BERNARDINI process is fully continuous and automated with all in-line controls and continuous measurement of the oil loss in the soapstock.

The plant is designed for utmost versatility, trouble-free operation and for coping with feedstock from the most different sources and with the widest range of acidity.

The plant is composed of the following main sections:

The number of centrifuges ranges, according to the process steps required , from 2 to 3 with the first centrifuge being normally of the self-cleaning type.

Combined cold neutralizing and winterizing

This plant has been specially designed by C.M. BERNARDINI to process sunflower and corn oils. It allows to perform alkali neutralizing and winterizing in a single step only.

The process is fully automatic and continuous. Moreover , as neutralizing takes place in the cold phase, it requires only two centrifuges:

The sunflower oil processed in this unit, where no filter aid is required, passes a cold test of over 48 hours at 0 °C.
