MicroPure Filtration launches mash filter presses for craft brewing efficiency

MicroPure Filtration has introduced mash filter presses designed to improve extraction efficiency and reduce operating costs for craft brewers and liquid processing facilities.

According to the company, the mash filter presses can reduce raw material, energy, and labor costs by 20-40% compared to traditional lauter tuns and other filtration technologies. The systems use membrane plate squeezing and micron-rated filter cloths to separate wort and extract from mash rather than relying on gravity, rakes, and circulation.

MicroPure said the filtration process can achieve extract rates exceeding 98% while supporting faster conversion through fine stripping mills with up to 20% flour. The company also stated that the design allows larger mash loads and shorter cycle times, increasing production throughput.

During operation, mash enters the press chambers through a feed pump while filter cloths retain grain particles and allow wort to pass through the system. After filling is complete, membrane plates expand using compressed air to squeeze additional wort from the grain bed. The system then drains the air pressure before the chambers open for cleaning and grain discharge.

MicroPure said the membrane squeezing process lowers moisture content in the spent grain cake, reducing waste volume and simplifying handling. The company also noted that the deeper membrane chambers require fewer chambers per hectoliter than non-membrane filter presses.

The mash filter presses support multiple brew styles and include automated operation features. Systems are available in capacities ranging from 1 to 200 hectoliters, with screen openings from 0.5 to 200 microns. Maximum squeeze pressure is rated at 100 psig, and maximum operating temperature is 200 degrees Fahrenheit.

MicroPure said the mash filter presses are intended for craft brewers, juice processors, and facilities extracting liquid from mashed or pulped materials.
