摘要:
A method and an apparatus are provided for testing the efficiency of a cleaning procedure for a filter in a filtering system. After the cleaning procedure (21) of the filter, the filter pores contain a fluid (22). The system is pressurized (23), and a decay in pressure over a predetermined time period is measured (24). Based on the pressure decay, it is determined whether or not the cleaning procedure has been effective (25); a pressure decay smaller than a predetermined threshold value indicates that the cleaning procedure has not been effective.

The disclosure relates to a method in the protein fractionation of skim milk by means of microfiltration. The skim milk is pre-treated in that, before the microfiltration, it is heated to between 55 and 65 C and kept at this temperature for between 2 and 15 minutes. Thereafter, the skim milk is caused to pass through one or more microfilters, in which event the skim milk displays a falling or alternatively maintained temperature curve.
