PROTECH NZ Rotating Disc with sieving ring Vacuum De-aerator

The vacuum de-aerator is suited for the de-aeration of liquid up to paste-like products, that have not been manufactured under vacuum and therefore contain air. The plant operates continuously and is usually the last unit in a production line.

Air-free products increase the accuracy in dosing of downstream filling units
Higher product density enables to reduce packaging volume
Easy maintenance and cleaning

Dimensions: 600mm OD top of cone tapering down to an 80mm outlet. Overall height 1020mm
Motor: 1.5kW
Sieve perforations: 1.5mm
Disc Diameter: 500mm
Product feed
The product is always fed via a feeding pump. This one can be an eccentric screw pump or a rotary piston pump. The feeding pump is not included but can be purchased separately from PPN.

Distributing system
By its dynamics the distributing system enables to efficiently de-aerate liquid up to paste-like products.

The product is fed via a pump. The product flows on the rotating distributing disc via the feeding pipe. Through the centrifugal force the product regularly spreads forming a thin film. It passes through the sieving ring and is projected against the inside wall of vessel. Under vacuum action in the vessel the air bubbles stretch, burst and are continuously sucked off by the vacuum pump.

The diameter of the perforations of the sieving ring depends on the application; it is comprised between 0.7 and 3 mm. Because the product in form of a thin film first flows along the inside wall of vessel and therefore remains longer in the vessel, an additional effect of de-aeration is attained. Achievable results: gas residual up to 1% and less.

Advantages
Prevention of oxidative modifications such as discolouration, alteration in flavour and aroma occurring especially in fat and oil.

Regular glossy product surface, enhanced long-time stability reached by de-aeration.

System optimally adjustable to the different products:
Air-free products increase the accuracy in dosing of downstream filling units
