To be honest I think the big issue we have here is that all the current CIP spray balls are really designed for large commercial tanks that are 1meter in diameter or larger. The issue is the spray ball design not really the pump. In larger breweries they would use a 300-1200watt pump for CIP and this size pump is expensive and really overkill. I my opinion I think what we need is a more efficiently designed CIP spray head that will spin and operate on much lower flow rate and pressure. If we were to design one that is made from plastic and work really well for tanks up to 500 mm in size I really think this is what we need in our opinion so customers can use the current
25watt and
65watt magnetic drive pumps.
It surprises me that nobody has designed a spray ball specifically for lower wattage pumps for smaller tanks.
I know a lot of you guys like stainless steel but if we make the spray ball from stainless we will then have to used bearings and because spray balls can't have lubrication in them they require a bit of pressure to get them spinning due to the resistance. If we design the spray ball from plastic we can use some slippery grades of plastic that slide well without bearing and if its quite light it will spin much more easily than stainless. If we use good quality engineering plastics we can design it to be strong, resist chemicals and boiling water. It's really just the perception of having a plastic spray ball in a nice stainless tank. Some customers just don't like the idea of plastic but I think for this application it's the way to solve the problem. Also plastic lets us use complex shapes that are difficult to machine from stainless and to get the CIP spray head to work in very low pressures we will need some complex shapes to direct the flow efficiently without loss in velocity.
Not a critique but an observation:
I have an SSBrewtech Chronical fermenter, and their 10 gal Brite tank as well. They are 304 stainless construction. Both have diameters of about 380mm.
I have their CIP ball. Checkout Newera’s website, but the same thing is on AliBaba all over the place.
I have a KeglLand bucket blaster too. Awesome bit of kit. Here’s what I do (for the fermenter):
- Whack a scoop of StellarClean into 5 lites of water in the bucket blaster
- take out the riser from the pump on the bucket blaster
- thread a camlock into the pump tee
- run a camlock to camlock hose up to the CIP ball
- put a waste out back into the bucket from the bottom port of the fermenter
- hit the power, RDWAHAHB
15 minutes later, all clean. In cases of extreme soiling, may need a wipe with a scotch brite pad (around the krausen line) and 5 minutes more CIP.
The Brite is pretty much the same, except just invert over the BB, with a line to a liquid in.
So easy. No more soaking. Absolutely clean, every time.
The moral of this story is the bucket blaster pump is adaptable. Adapt it!
