How to start a potato starch production plant?
Potato starch processing plant
Potato starch is a fine powder made by extracting starch from raw potatoes in potato starch production plant.Potato starch is very refined starch contains typical large granules and minimal protein or fat. This make the potato starch powder with clear white colour, and the cooked starch typical characteristics of neutral taste, good clarity, high binding strength, long texture and a minimal tendency to foaming or yellowing of the solution.
How to produce starch in potato starch production plant?
The production process of potato starch production plant include seveal steps: potato cleaning and washing, potato wet milling, potato starch extraction, starch milk refining, dewatering of refined starch milk and starch drying.
Potato starch processing plant
The description of potato starch production in potato starch production plant:
1. Potato cleaning and washing in potato starch production plant
The washing conveyor and the special designed washing machine will washing the potato and remove the solid impurity, such as sand, small stone during the transportation .
Potato cleaning and washing machine
2. Potato wet milling in potato starch production plant
The potato is always milled by the hammer mill after cutting into small piece.The purpose of the milling process is disruption of cell walls and release as much starch as possible for extracting potato starch .
3. Starch extraction in potato starch production plant
The centrifugal sieves is used to separate the starch milk and the fiber for starch extraction .
4. Starch milk refining in potato starch production plant
For making high quality potato starch, raw starch milk will be purified in the refining process. This involves the removal of small fibers from the starch milk and then the removal of juice water and starch milk condensation. For this purpose, the hydrocyclones are commonly used.
Refining and concentration starch milk by hydro cyclones is the advanced technology in nowadays.
Potato starch processing vacuum dewatering machine
5. Dewatering starch milk in potato starch production plant
Dewatering starch milk is to remove the excess water by rotary vacuum filter, after dewatering,the wet potato starch with moisture content around 38% .
Potato starch drying machine
6. Starch drying in potato starch production plant
The potato starch drying machine will dry the wet starch with hot air in few seconds.Then,the starch is separated from hot air in cyclones. Due to short time of high temperature drying and intensive water evaporation from the starch granules, its surface is heated only to 40 °C. The potato starch after drying with moisture content around 13% .
My company can supply the complete potato starch production plant machine and equipment. We can design the potato starch production plant in full autoamtic or semi-auto according to different customer requirement and budget.
