The starch undergoes thorough dehydration to meet the standards of the commercial product, as it needs dewatering of up to 20% of moisture. Potato starch production line sluice valve is equipped in the outlet end of the flow trough, by regulating valves open degree to control the proportion of potatoes and water in the whole flow trough and evenly conveying them into the de-stoner to ensure efficient working of the de-stoner. In order to guarantee potatoes to be able to pass flow trough smoothly, a jet of water from circulating pond is pumped to impact and convey potatoes, to ensure the potatoes won't be jammed. Smoothness, shape and slope of a flow trough are crucial for the drifting of potatoes.
Features of POTATO STARCH PRODUCTION LINE:
1,when design air flow drying system,we fully considered each factor of turbulent flow ,cyclone separating and heat exchange ect.,so that each collocation and parameter have definite theory basis.

2, part control with starch is made of stainless steel.

3, the product quantity and precision are greatly improved.

4, the feeding quantity and inlet steam volume can be automatic adjusted ,thus the water content of product could reach the technology requirement.

5. this kind airflow dryer not only suitable to all kinds potato starch production line to be dried ,but also adaptable to the drying of corn starch and wheat starch.
The handling of the potato starch production line in this stage is a complex process, since it has to be dewatered without using high temperatures, in order to avoid gelatinisation – the destruction of its granular structure. Dewatering is usually a two-stage process: first the excess water is removed using a rotating vacuum filter, followed by further drying the starch without pasting it, by using a pneumatic dryer. High temperatures may be used in this last stage, at the end of which starch loses the final percentage of water, to achieve 20% moisture.
