DAF3 Candle filter with kieselguhr 2200L/h

 20257 excluding tax

DAF3 Candle filter with kieselguhr 3m2  for beer or cider filtration with dosing equipent and internal auto-rinse . Recommended product flow rate 1500-2200 liters per hour. Candle filter with kieselguhr DAF3 is placed on a rigid frame provided with castor wheels for easy relocation. It is used in beer filtration using of alluvial filter (diatomaceous earth) to the vertical filter candles. The filter is fitted with a metering pump which supplies the diatomaceous earth at regular doses, which ensures a continuous throughput of the filter candles. For visual inspection of filtered beer inside the filter components, the most important sites of the filter are equipped with a flow-through sight glass. The container for the filter candles is constructed using pressure PN10 flanges for easy disassembling.

Beer filtration through the candle filter with kieselguhr is the most common solution of a filtration in a microbrewery of medium and large sizes . Beverage filtration is done through a layer from the filtration material that is flooded on the vertical filter candles . Candle filter with kieselguhr is characterized by high filtration efficiency . The most widely used filter medium is diatomaceous earth (kieselguhr). Depending on the composition of the filter layer different degrees of purity and flow of filtered liquid can be achieved . Ongoing diatomaceous earth dosage by a dosing pump keeps the filter still enough permeable . This allows to achieve high -capacity performance. Cleaning (regeneration ) of the filter is very easy and fast, without disassembling the pressured vessel

candle-filtration-elementThe filter is fitted as standard with the flow-through sight glass at both the inlet and outlet . It can be equipped with various level of automation. The filter is designed as a mobile device placed on travel wheels

How works the filtration of beverages via the candle filters with diatomaceous earth ?

The layer of diatomaceous earth is applied to the support structure of the filter candle.
The candle is a cylindrical element that are made of stainless steel wire with trapezoidal special cross-section design, ensuring high deformation resistance and durability of these carriers.

Hence result a high filtration efficiency – the possibility of using filter for both coarse filtration and fine filtration – before a secondary micro-filtration that is provided on special microfilters.
Filtration by candle diatomaceous filter characterizes a very low cost filter material and very inexpensive operation.

 

IMPORTANT:

Filter performance depends mainly on the parameters of the filtered product – viscosity, amount and nature of the substances contained in the filtered product, on the type of filtration material,on the total filtration surface, and on pressure loss.

 

 

 


Description of the DAF3 filter:

DAF3, the candle kieselguhr filter is placed on a rigid frame provided with castor wheels for easy relocation. It is used in beer filtration using of alluvial filter (diatomaceous earth) to the vertical filter candles. The filter is fitted with a metering pump which supplies the kieselguhr at regular doses, which ensures a continuous throughput of the filter candles. For visual inspection of filtered beer and filter components, are the most important sites of the filter fitted with sight glasses. The container for the filter candles is constructed using pressure PN10 flanges for easy disassembling.


 

The main benefits of this type candle filter with diatomaceous earth  :

  • high filtration efficiency
  • easy filter maintenance in terms of sanitation
  • large number of filter cartridges provide high capacity power
  • filter mobility
  • simple operation
  • small cost of consumables – diatomaceous earth
  • using both primary and secondary filtration – choice of diatomaceous as a filtering material
  • stable flow filtration performance – it does not decrease until fully clogging of the filter layer
  • quick and easy cleaning (regeneration) of the filter without removing the device
  • the possibility of automatized operation

Cleaning of the filter

Rinsing of the candles : it is carried out easy via the water backflow through the filter, without disassembling of the filter or pressure vessel.
Blasting silt with a compressed air : The filtration cake is blasted out from the filter housing and then it is subsequently pushed out from the candle by compressed air – all done via the opening and closing of valves, without a disassembling of the filter or pressure vessel.
