Nortek HDT filter: the perfect balance between traditional filtration technology vs. novel construction concept.

Nguyen, M.-T.

Abstract
An automatic thin bed mash filter, featuring recessed polypropylene plates (to which the filter cloth is internally fitted using a new method which is claimed to facilitate more thorough CIP and thus improve hygiene), mash inlets at both top and bottom (designed to combine low oxygen uptake with balanced filling of all compartments) and an automatic spent grains discharge system is described. It is stated that this mash filter can process 12 brews in 24 hours and achieve brewhouse wort yields equalling or even exceeding the laboratory extract yield.
