Abstract
The present invention refers to filtering method and a filter device for filtering liquids, especially beverages. The filtering method and the filter device are to be reliable and simple without any negative influence on the quality of the filtrate. A filter is produced in a precoating station by precoating with a filter aid, the filters being then removed from the precoating station together with the filter carriers and introduced into a filtering station, where they are stacked up like a tower and pressed together.

A process for filtering liquids comprising the steps of:
- depositing a filtration aid on substantially flat filter carriers (2) to form filters (3) on the filter carriers (2) at a depositation station (1) without adding binding agents to the filtration aid or filters (3);
- then, removing the filter carriers (2) and the deposited filters (3) from the depositation station (1);
- then, introducing the filter carriers (2) and the deposited filters (3) into a filter station (4) and stacking them in a vertical tower;
- then, pressing the stacked filter carriers (2) and filters (3) together;
- thereafter, supplying a liquid to be filtered to the filters (3) which are on the filter carriers (2) in the filter station (4), wherein said liquid flows through an inlet in a sidewall of a respective carrier above the filter, through the filter, and out through an outlet in a sidewall of said respective carrier below the filter;
- and then, removing a filtrate from the filter station (4).
