Heinen Freezing of Germany has introduced compactduo, a more powerful version of its compact. Rather than a single drum system (types c11, c15, c18 and c21), the compactduo has a double drum (types c22, c30, c36 and c42), three different layout versions and a capacity of up to 1.500 kg/h. The dimension are small at 2,800 x 3,100 x 10,600 mm. The entire system can be delivered at short notice and set up in five days, a company statement said. They installed four of the new systems in 2005 and say customers have found them to be a good solution for small and medium capacities at an attractive price.
Heinen says it can also add optional features to their basic models, e.g. a programmable, air-cooler, rinsing device for the Arctic series, This now does
two jobs for one: the warm water sprinkling on the air cooler allows a considerable reduction in the defrost cycle in all freezing systems. Secondly,
the connection to the programmable cleaning means the air-cooler hood is automatically cleaned, meaning less labour costs and better hygiene.
The same applies to the design of the
air flow against the air cooler. Heinen patented this in 2004. The effect is to provide more surfaces for distribution of snow and ice deposits, giving longer production without a defrost. It lessens the potential for freezers to operate at the threshold of shift-defrost, frequent-defrost, and avoids having to install other aids such as snow blow-off or the use of the industrial version of defrost – the “sequential” defrost. When production demand goes up, one can upgrade with the usual systems (snow blow-off system or sequential defrost).
Heinen says it is working on more improvements, e.g. a condition-monitoring-system (CMS) for particularly big industrial systems -shift.
