Rasping & Extraction |
|
|
 |
 |
Pulp is the residue after starch extraction. The pulp is an excellent cattle feed. |
Concentration |
|
|
Concentrated
Crude Starch Milk |
 |
The crude starch milk is concentrated and excess potato juice isolated. Potato juice
contains the soluble nutrients of the potato.
The juice is an excellent fertiliser and is recycled to
farmland.
The juice has also been used for animal feeding |
|
|
|
 |
 |
The residual juice is removed from the concentrated crude starch milk by washing with
pure water. The residual juice is diluted with the washing water as "fruit
water".
Fruit water is an excellent fertiliser. |
Dewatering & Drying |
|
|
 |
Exhaust Drying Air |
The purified starch milk is dewatered and dried ready for a multitude of application
in food and technical industries. Starch is a pure, renewable and versatile polymer. |
