Horizontal Peeler Centrifuge

(Horizontal Discontinuous Separation)

Peeler centrifuge operates on the principle of centrifugal force to separate solids from liquids by density difference.

The high rotation speed provides high centrifugal force that allows the suspended solid in feed to settle on the inner surface of drum. The washing processes are performed at the same rotational speed and in same centrifuge vessel.

The unique feature of Peeler Centrifuge Horizontal Peeler Centrifuge is the constant basket speed which allows all operations like feeding drying discharging to be carried out at full basket speed.

Rotofilt Peeler centrifuges are offered both in the batch and continuous centrifuge processes. This process are determined to achieve maximum removal of solid from liquid that may be required to be as pure as possible and not be easily separated by differences their densities.

Application

Horizontal peeler Centrifuges are successfully used in Food Stuff, Pharmaceutical, Plastic, Organic & Inorganic Chemicals Industry for separating solids from solid liquid slurry with 5 to 50% solids contents and particle size ranging from 2 microns to 10 mm. Products which are difficult to filter or decant can be easily separated using Peeler centrifuge.

Peeler Centrifuge is used for:

AlumiAmino acids, benzoic acid, benzene, hexachloride, calcium hypo chloride hexachlorocyclohexane insulin, potassium bisulphate, sodium perborate, penicillin, sulphur, starch, etc.

Process

The unique feature of Horizontal Peeler Centrifuge is the constant basket speed i.e. all operations like feeding, drying discharging etc. are carried out at full-basket-speed. The sequence of Operations can be (either semi or fully automatically) controlled by Electro-hydraulic control panel / PLC controller

Typical Process Cycle

  1. Feeding: The Suspension is fed from the Storage tank to the basket rotating at full operational speed
  2. Removal of mother liquor: Under the influence of the centrifugal force the Liquid is drained from the solids, through filter elements (usually filter cloth). The solids are collected as ‘cake’ in the basket.
  3. Washing:  If required, in order to remove the traces of mother liquor washing facility can be provided to thoroughly wash
    the solids during separation.
  4. Re-drying: After giving wash or other treatment solids are further allowed to dry.
  5. Discharging: Solids are ‘peeled’ off by means of full-basket-width scrapper and is discharged through chute in front cover of
    the machine or conveyed by discharged screw.
