Abstract: A method for filtering a dairy product is used in a filter system that includes at least one pump loop having a pump and a filter, with the pump being arranged to feed a feed product to the filter for filtering the feed product and outputting a permeate product and a retentate product. The method includes supplying the feed product to the pump at a feed pressure, during a first operational mode in which the feed pressure is below a first predefined threshold, controlling the pump to operate at a first power that is within a first percentage range of a maximum rated power of the pump, and during a second operational mode in which the feed pressure is above the first predefined threshold, controlling the pump to operate within a second percentage range of the maximum rated power which is higher than the first percentage range.

Abstract: A method for concentrating a substance in a milk product, the method including the steps of: feeding the milk product from a tank to a filtering device, filtering the milk product into a permeate and a retentate: such that the substance is concentrated in the retentate, circulating a first part of the retentate over the filtering device, feeding a second part of the retentate to the tank, repeating the circulations to thereby gradually increase a concentration of the substance in the milk product, and stopping the repeating when the concentration of the substance in the milk product has reached a predetermined value.

Abstract: A support device is provided to facilitate assembly and/or disassembly of a filtration unit of a membrane filtration apparatus, which may be configured for production of a food product, by supporting a membrane element during the assembly and/or disassembly. The support device includes an engagement portion which is configured to detachably engage an end portion of an elongate housing of the filtration unit. The support device further includes a platform portion that projects from the engagement portion and is configured to support the membrane element during loading and/or unloading of the membrane element through an opening in the end portion.
