Sheet filtration

Our plate filters are suitable for the filtration of wine, cider, fruit juices, beer, vinegar and, with an appropriate pump, oils. All the filters operate on the same principle: a series of cellulose-based filter sheets is clamped between filter plates in a way that allows each sheet to operate independently - in parallel.

Filter sheets are available in different grades of porosity and it is therefore possible to use the same machine to achieve different grades of filtration - from coarse filtration to remove visible haze to sterile filtration prior to bottling. The working life of the filter sheets, and the amount of product which can be filtered through a given number of sheets, is determined by the condition of the product and the grade of filter sheets. We give an indication of the capacity of each filter: the higher figures refer to coarse filtration and the lower figures to sterile filtration. These figures are reasonable estimates and may vary between products. During use the filter sheets become clogged with the particles being removed from the liquid and must eventually be discarded and replaced. When filtering smaller batches of a product it is possible to use most of our filters with less than the full complement of filter sheets. This reduces wastage of filter sheets.

Our filters are supplied with clear, easily followed instructions and are quite simple to operate.
