A complete set of potato starch equipment

1. Raw material reception unit
The unit is the first step of potato starch processing. The main purpose of this unit is to preliminary remove impurity and put them into storage pool.

When unloading potatoes, it is better to use special shovels to prevent the potatoes from damaging. Potato storage time can't exceed half a month. The longer the potatoes are stored, the more adverse for the starch production.

Attention must be taken that potatoes should not be damaged at time of purchase. Damaged potato is perishable, and the rotten potato will affect the potatoes around easily. The quality of potatoes has very big influence on the quality of potato starch.

2. Hydraulic transport unit
The main purpose of this unit is to convey potatoes of the potato storage tank into conveying screw elevator and conveyor by flow conveying, and then convey them to a de-stoner through a flow trough. In the process of conveying, potatoes continuously roll and clash in stream flow to peel off sticky mud of potato, it plays a very good cleaning effect.
In the production of starch, the cover of the flow groove which is near the outlet end of the potato storage tank is opened, and then washing water is pumped into it from the other end of the flow groove. Potatoes enter into the de-stoner evenly through flow conveying along the flow trough. A 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. The bottom of the flow trough designed by us is half round and the slope is reasonable, The flow trough can convey potatoes evenly into the de-stoner. A washing and conveying pump is added separately which can ensure the flow trough not being air-logged under improper operation circumstance.
