Preparation

Seed preparation prior to extraction differs according to the seed to be processed.

This step is very important as it affects final oil yield and product quality.

Seed preparation process for many type of seed basically includes:

Cracking

It is used in the preparation of oilseeds prior to expelling or solvent extraction.

It is performed by means of cracking mills, single or double pass, which are composed of corrugated roller mills

Cracking mills carry out the essential first step by breaking raw material into small uniform pieces.

Cooking-Conditioning

It aims at obtaining, by means of cookers-conditioners, the best conditions prior to flaking by heating and adjusting the moisture content of the various oil-bearing materials to be subjected to prepressing or extraction processes for the removal of the fat contained therein.

Flaking

It is performed by means of flaking mills, which are equipped with smooth rolls.

They are particularly suitable for flaking oilseeds (specially soybean) before solvent extraction or pre-pressing in order to obtain a very low residual oil content in the meal after the extraction process.
