High pressure steam peeling plant

Versatility
The plant is capable of peeling products such as potatoes, carrots, beets, celery roots and tubers in general, by the use of steam at high pressure.

It consists of:
- wire net elevator with flights
- accumulation and weighing hopper
- steam peeler
- steam expansion vessel for solid waste separation
- scrrew elevator to feed the product to the brushers
- dry brusher with positive screw
- washer brusher with positive screw
- electric control cabinet

High strength, hygiene and reliability
- galvanised steel frame
- wire net elevator and flights in AISI 304 stainless steel
- weighing hopper manufactured in stainless steel 304 with conveyor belt located on the bottom for product discharge into the peeler
- steam peeler in AISI 304 stainless steel
- electro-pneumatic ball valves for inlet and discharge of steam
- pneumatic device for opening and closing the peeler
- automatic instruments for steam pressure control
- steam expansion vessel manufactured in galvanised steel
- AISI 304 stainless steel screw elevator, with large feeding hopper
- brushers with special brushes supported on ball bearings, and positive product feeding screw manufactured in AISI 304 stainless steel
- electric panel board with synoptic and timers, which allow adjustment of the feeding time and steam-product contact time.

Maximum yield, minimum consumption:
- possible high pressure working operation, together with a special steam distribution inside the peeler, allowing a drastic reduction of the product-steam contact time
- consequent increasing of the peeling yield minimising steam consumption
- the weighing hopper guarantees a constant quantity of product inside the peeler, avoiding waste of steam
- the large steam expansion vessel dimensions allow two important effects:
immediate pressure discharge with "shock" effect on the product which helps the separation of the peel "expansion chamber" effect which guarantees a perfect elimination of the solid waste
- the dimensions of the screw elevator hopper provides a buffer stock which enables the line to work continuously and regularly
- the positive screw inside the brushers, allows a precise product timing regulation according to the quality and the ripeness of the raw material
- the two brushers guarantee a perfect peeling operation, even with particular products, and a drastic reduction of the water consumption because the first brusher works practically without water.
