General Information:
The HopRocket
tm
can be used as a hop-back, an inline hop infuser (Randalizer) and a general purpose
particulate filter. However, the product is intended for whole hops only. Pellet hops will pass through
the filter screen and in excessive quantities will plug it. For this reason we do not recommend it for
recirculation type chilling systems since all of the particulates and trub will be forced through the hops
in the HopRocket and may lead to plugging of the unit. Please use the following guide for capacity and
flow recommendations for successful operation of the product. Since hops and individual systems vary
significantly some experience and adjustments of flow and technique may be needed.
Hop-back operation: use of the cylindrical insert is recommended in this application to increase flow
capability through the product. A maximum of 3oz of whole hops is allowed with the insert in place.
Using more hops than this will damage the product as the hops swell. In addition, limit flow to a
maximum of 1 GPM (3.8L/min) to avoid compacting the hop bed which will plug the unit.
Hop Infuser: it is not necessary to use the cylindrical insert in this application since the hops are much
less restrictive and less likely to compact at cold temperatures. Max capacity without the insert is 4oz
for this application. It is recommended that the 4” stud be installed so that hop particles don’t pass
through the stud hole in the screen. Particles of this size may plug a 3/16” ID beer hose.
General filtration: flow rate will be highly dependent on the type and quantity of material being filtered.
Experimentation with your specific system and process will be required.
Sanitation:
Caution:
do
NOT
use any cleaner or sanitizer containing
chlorine
such as bleach. Over time, this
will pit and erode stainless steel.
Any other non-chlorine sanitizer is acceptable to use. Iodophor
TM
or StarSan
TM
both work very well and
do not require rinsing.
Disassemble all parts and soak in sanitizer. It is not necessary or recommended to soak the band
clamp or t-bolt in sanitizer since these parts do not contact the wort. Over time this can damage the
threaded surfaces of the clamp.
To assemble the HopRocket
tm
it is easiest to use a carboy drainer/stacker to rest the canister on in an
inverted position as shown in Fig 2. Install the threaded stud into the hole in the fine perforated screen
using the hex nut and the wing nut as shown in Fig 3. Then install the perforated cylinder and cap over
the stud and secure with the remaining wing nut as shown in Fig 4.
Caution:
DO NOT over tighten the wing nut or you may damage the product! A slight pressure is all
that is needed to hole the cylinder securely in place.
Lastly, install the black silicone wiper seal onto the fine perforated screen and insert it into the canister
pushing it all the way down until it seats on the ledge at the bottom of the canister as shown in Fig 5.
TIP:
It is easier to install the assembly into the canister walls if they are still wet from the sanitizer.
