The Bühler PolyCool 1000 is a a high-performance cooling die that, together with an extruder, provides an efficient and flexible solution for food producers creating sustainable plant-based meat or fish alternatives. With the PolyCool 1000 cooling die in combination with an extruder, it is possible to produce wet-textured proteins based on a wide range of raw materials including soy, pulses, oilseeds, upcycled side streams like brewer spent grains, as well as newer ingredients such as microalgae, at throughputs of up to 1,000 kilograms per hour. The PolyCool 1000 enables production of products of different shapes and structures while meeting the standards required by industrial-scale production.
The individual cooling circuits can each be controlled independently to determine the product’s final texture. The high-capacity cooling die can withstand pressures of up to 50 bar as it cools down the melt from some 150 degrees Celsius to below boiling point. With its electropolished surface, the extruder and the PolyCool 1000 are easy to clean and meet all hygienic design standards to maximize food safety. The PolyCool 1000 is also easy to assemble and disassemble.
