Experiments
Of course, the above expression model was calibrated and validated by means of experimental results collected at pilot plant scale in a relatively small membrane filter press. It contained five filter plates making 4 filter chambers, each with 2 cross-flow areas of about 40 cm x 40 cm, creating 3 cm wide filter chambers. The flow resistance of the filter cloth was half a mm in thickness and made out of polypropylene. The edible fat crystal aggregate slurry was prepared in an on-site crystallizer and then pumped by a slurry pump into the filter chambers. The liquid produced during the expression process was collected in a bin standing on an electronic balance to register the flow rate.
