Regenerative beer stabilisation solution for small breweries

20 September 2019

Regenerative beer stabilisation technology, from KHS is now also available for smaller breweries with yearly outputs of up to 70,000 hectoliters with the launch of the ECOSTAB family. 

The Innopro ECOSTAB product line offers regenerative stabilisation using polyvinylpolypyrrolidone (PVPP) in a process that removes some of the haze-forming polyphenols from beer. 

First, a frequency-controlled pump doses PVPP into the product line. The beer is then stabilised in a small module where the PVPP is retained by bound tannin molecules. "Since the PVPP doesn't remain in the beer, the result is low mixing phases, low media consumption and reliable production," said Gerold Tandler, head of product management process technology at KHS. The PVPP in the modules is then regenerated and returned to the dosage tank where it is ready for the next stabilisation cycle. Regeneration improves the use of raw materials significantly.

To date, this technology was intended for large and medium-sized breweries: developed for continuous stabilisation, the Innopro ECOSTAB C with an output of 150 to 600 hectoliters per hour is suited for companies with an output of more than 400,000 hectoliters per year. The Innopro ECOSTAB B stabilises between 50 and 240 hectoliters per hour in batches and is thus the suitable solution for companies with yearly outputs of more than 50,000 hectoliters.

With the Innopro ECOSTAB S, KHS now offers its customers its tried-and-tested solution in a smaller size. Thanks to its compact design and movable base, the Innopro ECOSTAB S is mobile and can be flexibly integrated as required into the production process.
