Amazon counter-pressure bottler
I'm not ready to keg yet, but I also wasn't happy with using a bottling bucket and priming sugar for carbonation, so I took an intermediate step. Found a guy selling 11 pallets of kegs for $20 each and got two of them that had carbonation stones.
So I did a closed transfer from my Fermzilla to the keg, and set it up for forced carbonation at 30psi (10 for the stone, 18 from a chart based on beer style and temperature, and another 2 just because). However, it was still carbonating after several hours, and I just stopped because I was afraid of over carbonating the beer.
But the main part of this post was to talk about the lever-operated counter pressure bottlers showing up on Amazon. I'd had mine in my list for months, and when I went to buy it the price jumped 15%. That pretty much sucked, and it wasn't noticeable BEFORE it went in the cart. I've had this issue with stuff I've purchased from Amazon before. As it was, it was 50% of the price of a Boel device or clone.
This device has 4 ports, and no instructions in english. Communications with the sellers didn't help, I had to figure it out. Basically, gas goes in the left upper port, beer in the right. The lower left port is for purging the bottle, the lower right port when cracked gets the beer flowing.
A few things this device needs:
- a backlight so you can better see where the beer is in the neck. I'll probably 3d print a mount for some Amazon light.
- a collection jar with a mount to the back to catch the foam. Probably will 3D print that as well.
- a drip tray to mount it to - there's a lot of drippage
- a means to clamp it down. If you have a big enough drip tray it might work without a clamp, but actuating the lever over-centers the device and tips it over.
- a hose to go from the nipple under the seal to the bottom of your bottles.
Other improvements:
- re-designing the linkage so that you can pull the lever from the front
- more common line sizes - all of the lines are 5/16 ID, nearly 1/2" OD. Could not find adapters at Home Depot, our local hardware store, or even McMaster Carr, so I made some by putting 1/4" compression sleeves inside my 5/16 lines, stuffing those into the 1/2" lines and hose clamping them. Worked fine, no leaks.
- instead of the compression connections at the machine for beer and gas, ball locks would have been much easier. And for some reason, they used a duotite fitting instead of a compression on the gas bleed line. if those compression adapters are 1/4 NPT on the machine side this will be an easy fix (but another $20)
Setup requires adjusting the upper clamp bolt (where the lever attaches at the top) to put enough spring pressure on the silicone seal when it sits on the bottle such that it won't lift at the pressure you are bottling at. This takes a bit of trial and error. I started at 20 PSI. Then you adjust the bottom clamp that the mechanism rests on when there's no bottle in it.
To use it you:
- lift the mechanism with the lever and place a bottle under the seal, and release the lever.
- Turn the handle to the left. Gas will enter the bottle
- turn the bleed screw to vent the gas out of the bottle; then close the bleed screw.
- turn the handle to the right. Beer might start flowing slowly, if not, crack the liquid knob on the right. It doesn't take much to really get it going. It is much faster than a bucket wand filler. Close the knob when the beer is just below where you want it, then return the handle to the center position.
- vent the pressure and foam in the bottle using the bleed screw again.
- wrap a towel around the top of the neck and lift the seal with the lever. Tilt the bottom of the bottle towards you and pull it out. Cap as usual.
It takes between 1.5-2 minutes per bottle, including the time it takes to remove several bottles from the fridge, filling, and capping.
So the biggest downside is that the fill level is inconsistent. Sometimes I got a lot of foam and had to push it out, sometimes I didn't. Sometimes when I'd remove the bottle I'd get a lot more foam, sometimes I didn't. As a result my bottles go from filled just at the bottom of the neck to within 1/4" of the top. I really don't have a handle on what the proper keg pressure and pressure to run the device ought to be.
