Chemical Peeler Centrifuge (HX)

Chemical Peeler Centrifuge (HX)

The Chemical Peeler Centrifuge is designed for high throughput industrial liquid or solid separation applications.

The Chemical Peeler Centrifuge offers fast and efficient filtration for chemical applications on an industrial scale, in an automatic and sealed environment. It is designed for high throughput industrial liquid/solid separation applications.

The peeler centrifuge is used for the production of chemical products where it is absolutely necessary to avoid contact between the product and the operators.

This version for the chemical industry, with a perforated basket or with rotating siphon, is normally used on products with good filterability. The cycle (loading, washing, centrifuging and cutting) can be performed at maximum speed, for high production rates while reaching lower residual liquid (or moisture).

Production Cycle and Design Advantages

Typical Applications

  • Petrochemical
  • Intermediates
  • Catalysts
  • Chlorides
  • Calcium Compounds
  • Sodium Compounds
  • Amino Acids
  • Agrochemical
    • Fertilizers
    • Herbicides
    • Pesticides
    • Fungicides
    • Active Ingredients

Highlights

  • Ideal for chemical applications
  • Horizontal basket assures even loading and uniform cake distribution
  • Lower residual cake moisture due to high centrifugal forces
  • Perforated basket or rotary siphon basket
  • Cake peeling at full rotational speed, obtaining a high hourly production
  • Laser cake detector (external to the process chamber)
  • Visual access to the process area from the front door and inspection ports
  • No contact between the operator and product during operation
  • Excellent wash result
  • Increased filtration capacity. The creation of a vacuum beneath the filter cloth increases the filtration pressure and boosts the filtration rate (fast filtration) (rotary siphon centrifuge)
  • Regeneration of the residual heel by backwash through the filter media increases the heel filterability without removing it (rotary siphon centrifuge).
  • Sizes range from 500mm (19.7 in.) diameter to 2000mm diameter (78.7 in.)

Discharge

  • Discharge at maximum speed
  • Knife scraper blade (peeler)
  • Steep solids discharge chute or screw conveyor
  • Heel removal assist with optional reverse blow back

Cleaning

  • The highly effective C.I.P. system (Clean-in- Place) uses a Washing Machine Effect cycle and spray balls.
  • Multi-purpose application: The C.I.P. system avoids cross-contamination between products from one campaign production to another, which makes the machine suitable for multi-purpose applications
  • Washing Machine Effect
    • The centrifuge is filled with the washing liquid up to a predetermined height and is put in rotation. During the automatic washing sequence, the basket rotates both clockwise and counterclockwise. The knife goes in and out so that the washing liquid reaches all points of the process area, including the discharge chute.
  • Cleaning with spray balls
    • The washing liquid is sprayed through spray balls on all the surfaces of the process area to completely remove any residue of product still present.

Machine Characteristics

  • Pressure tight to 400mm H20 (0.6 psig)
