Large Production Automatic Bottom Discharge Sugar Separating Centrifugal Machines with Bag-pulling
Brief introdcution
PPSBD centrifuge is a kind of vertical centrifuge with PLC control automatic filtration type and down scraping discharging, which adopts continuously running and intermittent discharge.
Driven by the motor, the basket revolves step by step to the speed suitable for feeding, then the products which is to be separated enter to the revolving basket through feeding pipe. Centrifuge would stop feeding if the products' volume amounts reach to the predetermined date and the speed raises higher for separation.
Suspension's separation can be made possible by filter cloth(or filter net)under the effect of centrifugal force. Liquid phase is draught out through filter layer and thrown into the empty chamber and finally discharged from the liquid outlet while the solid phase reminds on the drum to from bucket-shaped filter cake which will be washed in the following steps. When filter cake meets the requirement of separation, centrifuge will be slowed down to the discharging speed.
The scraper begins to take effect and scrape the filter cake from inner wall to the products outlet of centrifuge.
Working principle
▷ When predetermined target is met and basket speed is suitable for feeding, feeding valve will be open automatically and product level detection begins to work.
▷ When layer thickness is thick enough to reach the product detection slab, feeding valve closes to stop feeding.
▷ Under the effect of centrifugal force, most of the liquid in suspension is thrown out through filter cloth and then flows into mother liquid tank through horizontal liquid outlet.
▷ With product dehydration going on, centrifuge will automatically slow down to washing speed according to technical requirement for washing.
▷ Washing valve opens automatically. With washing liquid rising to a certain height, washing valve closes and centrifuge speeds up automatically for further dehydration(secondary filter).
▷ After operation, product will be fully dried. Then discharging valve opens and discharging cylinder begins to work when
centrifuge automatically slows down to predetermined speed.
▷ With scraper rising spirally and automatically,solid product is scraped down into the hopper equipped with spiral discharger: With constant motion of spiral discharger, product is pushed out and discharged through valve.
▷ Scraper rises closer to filter cloth with a certain distance till the bar on scraper device approaches proximity switch to stop scraper rising then retreats quickly after a short stay(about 15s)then enters next cycle.

Main characteristics
♦ It is fully conformed to GMP CGMP Norm and meet the requirements of asepsis raw medicine production.
♦ With absolute isolation between power area and process area.It is suitable for occasion when customer requires high quality cleaning to avoid the contamination to product.
♦ The out shell bucket can be opened, so the whole internal parts can be observed and easy for touch wiping and cleaning.
♦ Perfect CIP system can be carried out to wash the internal parts of centrifuge to avoid cross contamination which are not easy to clean.
♦ Unique pneumatic counter-pulse device is equipped, which can remove remnant filter cake as much as possible.
♦ Totally-enclosed structure equipped with inert gas protection is adopted to be used in ex-proof 1 section.
♦ The automatic residual cakes removing device is optional (have owned the national patent).
