Potato

By-products:

The major constituents of the potato are:

Fibre (cell walls, peel)
Starch
Juice

Rasping & Extraction

Crude Starch Milk Pulp Pulp is the residue after starch extraction.

The pulp is an excellent cattle feed.

Concentration

Concentrated
Crude Starch Milk

Fruit Juice 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

Pure Starch Milk Fruit Water 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

Dried Starch

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.
