Hi, just wondering if anybody has created an equipment profile for a PBST 5BBL 2-vessel electric brewhouse.
I'll be using a Grainfather for trial batches and scaling the recipes up to the 5BBL production system. So I have made an attempt modify the BS Grainfather profile with the values that I think I can work out, but am open to input from anyone with experience on either pieces of equipment.
Cheers
Brad

- Batch Size: 23.00 L (600 L?)
- Mash Volume: 22.60 L (prob 120 kg grain + 350 L water expressed in L)
- Boil Volume: 28.00 L (650 L?)
- Mash Tun Weight: 9.30 kg (weight of the mash-tun is very hard to calculate/estimate)
- Evaporation Rate: 8.9 % (we will probably have the large exhaust port open to atmosphere)
- Mash Tun Specific Heat: 0.12 cal/g-deg C (this is probably the one that we really can't work out ourselves)
- Boil Time: 60 (this will be standard but may be 90 for pils malt)
- Mash Tun Deadspace: 7.00 L (any qty below the drain-port under the false floor - I haven't seen under the plates yet)
- Top-up for Boiler: 0.00 L (process dependant)
- Equip Hop Utilization: 100.00 % (ie approx 33% of AA isomerised in 60 mins - likely to be higher according to Brad's recent article)
- Losses to Trub/Chiller: 2.50 L (we can calc hose losses between PBST heat exchanger and FV)
- Cooling Loss (%): 4.00 (seems about right for contraction from 100C to 15C for a 10P wort)
- Top up water for Fermenter: 0.00 L (process dependant)
Cheers
