4.2 Insertion of Filter Sheets

  • Filter Sheets should be inserted with one sheet between each set of plates. The sheets have a rough and a smooth side. The “smooth” side appears to have a very fine crosshatch pattern to it while the “rough” side appears similar to frothy milk. The sheets need to be inserted into the machine in a rough-smooth-smooth-rough pattern, starting with a rough side facing the end plate at the pump side.
  • Each of the plates has a barb which accepts an included 4 mm rubber gasket to seal the system. There are two thinner, 2 mm gaskets included as well. These gaskets are inserted between the terminal filter plates and the steel endplates which are part of the frame of the filter, at the Pressure Regulator (13, Sec 2.1) and the handwheel-side plug (9). Once everything is in place, tighten the handscrew so that there is sufficient pressure to seal the system while it is running – this will need to be pretty tight.
*Note: Do not leave any spaces between the plates empty. If you run short of pads, remove the appropriate number of plates so that the filtering set up runs sheet-plate-sheet-plate all the way through. Failure to “fill” the filter with sheets will result in leakage during use.

4.3 Use of a Double Filtration Plate

  • MoreWine!’s plate filters can be outfitted with a Double Filtration Plate (WE915 / WE916) which allows you to create two “chambers” where filter pads of different micron ratings can be used in serial to one another.
  • Note that due to the need for the extra end plates on either side of the separation plate, it may not be possible to fit as many pads into the filter.
  • Also note how the position of the Plug / Stopper (9, see 2.1) and the Barb for the Outlet Tube (12) have changed position to accommodate the double filtration
  • DO NOT use pads with different micron ratings in the same “chamber” during double filtration.

4.4 Connecting and Running the Filter

It may be helpful to you to refer to the diagrams in section 2.1 (p.X) while reading this part of the instructions. The different parts of the machine will be referred to with the same numbers that they are listed as earlier in this paper. It is important to double check that all connections are tight and there are no leaks prior to running your actual product through the filter. Circulating a sanitizing agent is a great way to do this. We recommend the use of SaniClean (CL27) for this procedure. Note that a small amount of seepage is normal during the filtering process, as this is part of how the system stays sealed. Seepage will collect in the drainage tray underneath the filter plates.
  • To connect the filter, attach your hose from the vessel containing the product to be filtered to the Product Inlet (15), and connect a tube leading from the Product Outlet (12) to whatever vessel you wish the filtered product to wind up in.
  • Remove the cap to the Priming Reservoir (14) and fill. Replace and re-tighten the cap.
  • Close the Pressure Regulator (13) about half way.
  • Turn on the motor.
  • Open the Sampling Valve (8) and allow the air to be evacuated from the filter. Close the valve only once there is no more air being discharged.
  • By adjusting the Pressure Regulator (13), set the pressure to about 4 psi (0.3 bar), maintain this pressure for 10–15 sec. Now adjust the regulator until it reads the correct operating pressure for the filter pads you are using
  • During operation, periodically check to ensure that the Pressure Gauge (11) is still reading correctly and consistently. Small adjustments may be necessary and are normal. 

If the product is not dispersed within a few moments of switching on the pump, double check to make sure that the Inlet Tube is correctly connected and that no air had made its way into the system.

  • When you’re finished filtering, or if the pads become clogged, turn off the pump motor and unplug the machine. Wait at least 3 minutes before loosening the handwheel to ensure that all pressure has dissipated out of the system. Using the Drain Valve (6), empty the collection tray.

4.5 Filtering Carbonated Products

One of the attractive features of a plate filtering system is that it is possible to filter carbonated products such as bright beer or sparkling wine. The essential part of this is that the receiving tank needs to be pressurized so that you do not lose too much of the carbonation of the beverage in the process. You will always lose a little bit of the carbonation, but it can be minimized. Here’s an example which lays out the principles – it’s pretty easy to do:
Let’s say that your beverage is already carbonated to 15 psi, just pressurize the receiving tank to 10–12psi and make sure that you run the filter at 1 bar (14 psi) or higher. Because the filter assembly seals by positive pressure, your beverage has no lower-pressure place to let its bubbles out into. By keeping the receiving tank at a slightly lower pressure than the delivery tank, you encourage any carbonation which is scrubbed out of the liquid on its way through the filter pad to travel down the pressure gradient and dissolve back into the product. This also encourages good product flow through the system. Once all of the beverage is in the receiving tank, turn the pressure up to whatever level of carbonation you desire in it. It is important to use reinforced tubing for the outlet when filtering a carbonated product.

4.6 Regular Maintenance

Before carrying out any maintenance or repair operation, be sure the machine has been turned off, allowed to cool and is disconnected from electrical power. Failure to observe these measures could result in serious injury or death.
  • The filter unit should be cleaned thoroughly after each use to remove any deposits from the product being filtered. MoreWine! recommends the use of hot water and PBW (CL25) for this procedure. Be sure to rinse thoroughly after the administration of a cleaning product. MoreWine! reminds you that observance of strict cleaning protocols in the brewery / winery is the most effective tool in preventing the infection of future batches.
  • It is possible to steam sterilize the system after rinsing it only if you are using NORYL plates. Standard MOPLEN plates cannot be steam sterilized.
