Tetra Pak has reduced the energy use of its separators by 40%, by incorporating a breakthrough pressure management technology, Encapt™, into the systems’ design.
The Encapt technology lowers the atmospheric pressure around the spinning bowl using a low-pressure pump, and the system is supervised by sensors that keep air friction minimal. Less friction means less energy required.
Combined with a unique AirTight design inside the bowl, where the whole system is hermetically sealed to ensure no air enters. With the inlet at the bottom, and the outlet at the top it saves the centre for outlet flow, and so requires less energy.
The Hydrohansu-type rotating cleanflow magnet recently introduced by Goudsmit Magnetic Systems BV of Waalre (NL) was developed in collaboration with producers of top-tier food products.
The driving force behind the development was a pressing need for removal of very fine iron (Fe), AISI 304 and 316L particles in the dairy industry, for products such as baby food, yet it is also suitable for use in the sugar and lactose industry. Rotating magnets prevent the accumulation of fatty powders on the magnetic bars and guarantee a high level of separation. The new magnet system is hygienically designed in accordance with the EHEDG guidelines and can be cleaned semi-automatically.
