​Dryers/coolers and peeling equipment

​Disc pastillators

Disc pastillators from ANDRITZ Gouda is an alternative to cooling belts and can be used with advantage if product purity combined with a simple system is required. 

​

The Disc Pastillators consist of one or more horizontal jacketed discs.
The discs are cooled with water or brine in a closed system so product contamination is avoided.

​

As the equipment is integrated in a hermetically sealed housing, either inert gas or dry air can be used to avoid condensation on the cooling plates as well as contamination.

​

The pellets produced are uniform in size and form (normally between 2 - 8 mm in diameter).

Paddle dryers/coolers

The paddle dryers are contact dryers for powder or pasty products, e.g. filter cakes and residual sludge. The machines can be used for both heating and cooling. Thermo oil, steam or water can be used as heating agent.

​

ANDRITZ Gouda’s paddle dryers are produced and sold in Europe under licence from Japanese NARA.

​

The paddle dryers are highly effective machines working with low air flows to prevent dust problems and to ensure low energy consumption.

​

Due to the closed housing the system can work under vacuum and is thus suitable for removal and recovery of solvents.

Drum dryers

From ANDRITZ Gouda we offer drum dryers for drying of viscose, adhesive and pasty products.

​

The drum dryers are continuously working contact dryers. The product to be dried is applied as a thin film onto the steam-heated drum.

​

The dried product film is scraped off the drum and is reduced in size for continuous processing or bag filling.

​

​The typical steam consumption for drying is 1.2 - 1.4 kg steam/kg water evaporation.

Drum dried products normally have a relatively high density.

ANDRITZ Gouda offers mill sifters for coarse size reduction of the dryer film from the drums and also for control sifting.

​

Certain products require pre-cooking or pre-sterilization for which ANDRITZ Gouda's JET-COOKER can be used.

​

For sharpening of scraper knives ANDRITZ Gouda offers special knife sharpeners.
