Abstract: A method and apparatus for cleaning candles in a candle filter using a cleaning fluid that flows inside the candle from the side of the filtrate, whereby said fluid is pressed in an opposite direction to the direction of the filtrate from the inside to the outside, through said candles, by a gaseous medium subjected to an overpressure. Water is or can be used as an appropriate cleaning fluid and air is used as a gaseous medium. The prior art teaches nozzle-shaped contractions that are respectively disposed on the outlet end of the candles or deflectors arranged inside the candle at a distance from said contractions, whereby the in-flowing cleaning fluid is deflected towards all sides in the direction of the inner walls of the candles, are provided for distribution of said cleaning fluid.

Abstract: The invention relates to a filter for the deposition filtration of liquids such as juice, wine, beer or the like. A filter packet (28) of plate-type filter elements (25), stacked one on top of the other, is disposed in a container (3), each filter element (25) having a hub (26) that is oriented in its position by a shaft (12) penetrating the filter packet (28). In the hub (26), there is provided an axial inlet line (36) for the material (18) to be filtered, which inlet line feeds by a plurality of inflow channels (46) which are situated to be uniformly distributed in the peripheral direction of each hub (26) and which lead substantially radially outwards. The inflow channels (46) open into an annular distributor space (47), from which the material to be filtered flows out. The material to filtered flows out via an outlet gap (45) situated above the inflow channels (46), radially into the space (29) between adjacent filter elements (25).

Abstract: With the method of processing liquids, fine to very fine organic and/or inorganic granular particles are used, whereby pursuant to the invention the particles are mixed and compressed together in a first step to form an agglomerate that is heated at least to a temperature that is near the melting point thereof. The particles are thereby fixed in place by being subjected to a process similar to sintering for a suitable length of time, whereupon the resulting agglomerate is screened, or reduced in size in a grinder, to a granular size that is suitable for an intended use. This enables stabilizing and filtering aids to be produced with predetermined or predictable physical or chemical properties that are suitable for specific processes.

Abstract: A method of filtering beverages and other liquids. To avoid the considerable ecoproblems encountered with the filter aids of known procedures, which must be thrown away, the filtering active structure of the inventive filter aids is maintained so that they may be reused as often as required. A mixture of filter aids of varying morphological and physical components is used, and constitutes a minimum of two components, namely one component of specifically heavy, chemically stable metal and/or metal oxide and/or carbon particles of fibrous and/or granular structure, and a further component, for building up the filter cake and increasing its volume, of synthetic and/or cellulose fibers having a fiber length of 1 to 5000 .mu.m and a fiber thickness of 0.5 to 100 .mu.m. To increase the filtering efficiency of the filter cake of the aforementioned components, a further component may be added that comprises fibrillated or fanned out synthetic and/or cellulose fibers, preferably having a fiber length of 500 to 5000 .
