Transfering from FV to BBT

Transfering from FV to BBT

Some customer asked: when we need to transfer the beer to bright beer tank from
fermentation tank. if it would be best to use a pump or CO2 to do so and if you could
also give us details on the steps that we need to take.

And there are 3 method used by our other customers:

1. How to set up the hoses and pump
Set up
Have a stainless T on each tank. Place a valve on the one side of each T (preferably the
perpendicular side). These valves are used as drains. Connect the pump to the straight
side of the T next to the FV. Then brewers hose (using an elbow if the pump points
vertically).

Steps
1) Sanitize your BT
2) Drain the sanitizer from the bright to the FV. Not into the FV but out the drain you set
up with the T and valve. You can use the excess sanitizing fluid for your parts buckets or
just dump it.
3) When the hose is completely full of sani close the drain next to the FV. Then open the
drain next to the BT to release the remaining fluid. This ensures that your hose is full of
sanitizer and there is no air!
4) Reverse the process with beer. Run the beer from the FV to the BT. Not into the tank but
out the valve on the T. Wait until the sani turns to beer then swap the valves and fill your BT.

2. using a pump to transfer beer tank to tank.
I recommend purging the brite tank with CO2 or Nitrogen and then building up a head pressure
in the brite tank. The pressure should be the same or a Little higher as in the FV and high enough
to Keep the dissolved CO2 in the beer. (which in your case with flat beer won't be high).

We then connect the headspaces of the two tanks with a length of small diameter hose and let
the head-pressures in the two tanks equilibrate. Then we pump the beer from tank to tank, the
pressure remains equal in each tank and high enough to prevent foaming and loss of CO2.
At the same time the beer in the FV is displaced by the air/CO2 mix from the Brite tank and air
uptake in the beer in reduced.

We use a pump with a frequency variable drive, and always lower the pump Speed when the
Level of the beer in the FV reaches the conus of the FV. We do this to reduce the formation
of a vortex as the tank then empties. The vortex is often a source of air uptake in the
transferred beer. If you don't have a fvd on the pump then slow the transfer speed with the
butterfly valve on the pressure (brite tank ) side.

3. use CO2 to transfer
If I'm just transferring beer (rather than filtering) then I use CO2 to transfer. I feel it's
gentler (more gentle?) for the beer. After sanitizing and purging the Brite tank and transfer
hose I bring the pressure in the Brite to 7-10 psi, then bring the Fermenter to 10-12 psi and
slowly open the racking arm valves. The 2 tanks will equalize pretty quickly, so I then begin
to bleed CO2 from the Brite tank. Depending on how quickly you feed CO2 into Fermenter
and how quickly you bleed from Brite, you can control how quickly the transfer goes.
