Filtration diatomaceous earth (kieselguhr) for the beverage filtration
How filtration based on diatomaceous earth works
The filter medium – diatomaceous earth (kieselguhr) is prepared in the mixing bowl. The basic filter layer is layered onto the surface of the filtration candle (made of stainless steel, in the shape of a spiral with a trapezoidal cross-section of the wire) by means of a circulating pump, when a kieselguhr is applied to the outer surface of the filtration candle in the stream of liquid (beverage) and creates a temporary filtration layer on it.
Diatomaceous earth filters – filters for diatomaceous earth filtration of drinks from our production
The filtered drink is driven by a circulation pump through a filter layer made of diatomaceous earth, in which turbidity-forming mechanical particles and yeast are trapped. In order for the filtration cycle to have sufficient volumetric capacity and economic efficiency, more and more diatomaceous earth on the candles is supplied continuously and in a controlled manner during filtration using a dosing pump. This maintains the filter layer in a permeable state with a relatively constant flow rate and filtration efficiency for a specified defined time. After the end of filtration, the filter layer of diatomaceous earth is removed from the candles by counterflow manually, semi-automatically, or fully automatically (depending on the equipment of the diatomaceous earth filter). Diatomaceous earth filtration is characterized by very low operating costs per volumetric unit of filtered liquid and high productivity and efficiency.
