PPC Series Horizontal Corn Starch Peeler Centrifuge

Product introduction

PPCS siphon centrifuge is a new type of product that is developed on the basis of the ordinary peeler centrifuge. Based on the siphon principle, this product discharges the filtrate out via a siphoning device or skimming device. The filtering impetus can be changed by adjusting the liquid level at the suction inlet of the siphon pipe (skimming pipe) to further regulate the filtering rate, handling capacity, cake moisture and washing effect. A back-flushing device is configured to realize regeneration of the filter cloth and improve the separation effect. With back-flush, scouring, siphoning and other functions by configuring special devices, the filter cloth can be regenerated completely.
The siphon-type peeler centrifuge is applicable to the occasions involving large-scale production and requiring low cake moisture and sufficient washing, and therefore is commonly used for the separation of starch, sodium bicarbonate, potassium chloride, calcium phosphate and other materials. Currently, it has been widely applied in such industries as pharmaceutical production, food production, bioengineering and chemical engineering.

Advantages

Horizontal structure and floating platform damping system adopted to ensure stable operation and suppress noise.
Back-flushing Device Residual cake and filtering medium soaked and flushed reversely to realize regeneration of filter cloth.

Working principle

Except centriufgal force like the other common centrifuges,siphon centrifuge also has a kind of siphon draught force similar to vacuum pipe.
When the centrifuge is of no load,the counter-pulse pipe feeds the liquid to siphon chamber and the liquid is forced to the clearance through the via hole on the drum of siphon chamber,Then air of siphon pipe is eliminated and a layer of liquid forms on the filtering media,so as to make the feeding more even ,then feeding starts ,the siphon pipe rotates to a certain position and it turns to a lower position required after a certain position and it turns to a lower position required after a certain period when the feeding is finshed.The siphon pipe turns to the lowest position (Max diameter place of siphon chamber)After the suspension liquid comes into the drum,solid products are left on the filter cloth while the liquid is forced to go through the filter cloth and internal drum and collected in the clearance between internal and external drum.Then it flows into the siphon chamber through drum and via hole ,Next,the liquid will be draught by siphon pipe and deposited solid will be dewatered and scraped by scraper which is driven by oil cylinder and then the solid falls out through hopper ,When discharging is finished,centrifuge begins to clean the mesh.The siphon centrifuge not only washes the filter cloth in the drum,but also feeds the washing water to siphon pipe,liquid can counter-pulse wash the filter mesh from the internal drum.The washing duration and times are decided by product characteristic and when the washing is finished ,carry out the next circulative processing cycle.
