CMF3-300 : Candle mechanic beverage filter with 3 candles and capacity 300 L/h

CMF3-300 is a mechanic filter with three housings for filtration elements in the candle shape intended for 3-stage filtration of water, beer, cider, wine, kombucha or other beverages. The filtration extends lifetime of the beverages. Filtration capacity is up to 300 liters per hour.

Mechanical filtration consists of three filter housings in which are placed three types of special polypropylene microfiltration elements with a permeable surface at the level of microfiltration with porousity 5.0 μm (to remove rests of the yeast) and 2.4 μm (to remove the proteins).
Third filter 1.0  μm is intended for the water filtration during the self-cleaning and sanitizing process – when the back flow is used.
The entire mechanical filtration set is mounted on a mobile stainless steel frame made of AISI 304 material.

Delivered with one set of the filtration elements (see bellow)

A special polypropylene microfilter meets all the requirements for food production in the EU (1935/2004 / EC) and the USA (CFR Title 21).

How to use the filter in the beverage production process :

Frequently asked questions:

How long is lifetime of the filtration material (filtering candles) ?

• If you will use only chemical sanitizing and you will not use hot steam then lifetime of the filtration elements is appoximally 1000 sanitizing cycles.
• Number of the filtration cycles is not limited.
• Then you have to purchase new filtration elements (candles). Its price is approximally € 995,- for one filtration candle.

How to do the cleaning, sanitizing and sterilizing of the filtration candles and the filter ?

• You need use a CIP station for the chemical cleaning and sanitizing of the filter. We produce this CIP station that fully suits this purpose :

• CIP-52 : Cleaning and sanitizing station 2×50 liters

Description of sanitizing cycle :

1. Countercurrent rinsing of candles with filtered water (through third filtration element).
2. Sanitation in the direction of filtration with alkalic and acidic solution.
3. Desinfection with Peristil (remove the filtration elements from the housings and put them to the Peristil solution, let them there up to next use).

Filtration scheme (two options):

1. Only with overpressure – without a pump: source tank with higher pressure > filter > target tank with lower pressure (or stainless steel keg)
2. No overpressure – using a pump: source tank > pump > filter > target tank (or stainless steel keg)

Does the filter clog during the filtration process and what is the procedure for cleaning the filter?

• The clogging rate of the filtering candles and the length of the filtering cycle depend on the amount of yeast in the beverage.
• If the filtering candles become clogged, it is necessary to perform a back-flushing  with water, which is filtered through a water filter (third small candle).
• If this does not help then the cleaning and sanitation with a CIP station, an alkaline and acidic sanitizing solution, is necessary to do, and sterilize them with Peristil.

What are loses of the beverage product when is filtered ?

• Product losses are almost zero. It depends on the amount of yeast in the tank from which it is filtered.

Is there a problem with the loss of CO2 after the filtration of the beverage, or is it necessary to saturate the beverage?

• Beverage is filtered almost no loss – with overpressure – the pump can also be used.

Is it possible to add another candle with a porosity of 0.45μm due to the microfiltration of the beverage?

• Yes, we can modify the design of the candle holder, add one extra housing with a 0.45μm candle for microfiltration of the beverage (removing of bacteria and colloidal substances). Price is + € 1190,-
