Carb Stone - SFC series 1.5”tri Clamp Fitting micro bubble diffuser stone for beer brewing – HENGKO

How to use the diffusion stone

1.The “stone” sits inside the keg near the bottom.

2.A hose barb attaches it to a length of tubing (generally about 2 feet of 1/4” ID thick wall vinyl hose) which is affixed to the short downtube under the “in” or “gas side” post.

3.When the CO2 is connected, it sends a tremendous number of gas bubbles out through the beer. The miniscule bubbles create a huge amount of surface area to help absorb CO2 rapidly into the beer. This is actually a miniature version of a device used by commercial breweries everywhere.

4.Carbonation should be virtually instantaneous, though the manufacturer recommends carbonating your beer at least a few hours before serving.

◆  HENGKO SS air stone is commonly used to aerate wort before fermentation, which helps ensure a healthy start to the fermentation process. The HENGKO 2.0 micron oxygen stone can be used to oxygenate wort using an oxygen regulator. The holes in the 0.5 stone are too fine to use it to aerate the wort with an aeration pump.

The 2 micron HENGKO inline carbonation stone have millions of tiny pores ,so that this diffusion stone will quickly oxygenate wort & carbonate beer/soda prior to fermentation,to lower fermentation times & not easily get clogged.

 Different micron stones produce very small bubbles, which are ideal for efficient absorption of the gas into your wort.

The most common use for this specific stone is to build an inline oxygenation assembly where the stone is threaded into a 1/2" NPT TEE, so chilled wort passes the stone on the way to the fermenter. It's important to limit the flow of oxygen in this setup to avoid over saturating the wort.

HEGNKO diffusion stone can be installed into the 1/2″ FPT fitting or 1/4″ diameter ,1/4" barb or other custom connector, to connect with compressed oxygen tanks , air pumps or kettle&wort chiller by hose.

The detail attention :
After carbonation, you can shake the beer keg. If do that, you beer can reach the best mouth-feel.high gravity beers may require more time because oxygen does not dissolve as easily in liquids with a high specific gravity.
It's important to clean and sanitize diffusion stones thoroughly before each use and after use. Install an air filter, ensure a clean air source or the air being fed into the stone is clean, to prevent contaminants from clogging the stone or infecting the wort.

To properly sanitize your stones, we recommend you run it in a sanitized solution for 5 minutes. If the stone becomes clogged we recommend boiling the stone for 1-3 minutes to sanitize & unclog the pores , help break down anything within it. If boiling is not an option, we recommend soaking in Star San. Star San will remove a majority of surface contamination/bacteria, but will not sanitize the interior of the stone which may or may not be contaminated. If the pores in aeration stone get blocked from handling give a 15 seconds dip in hydrochloric acid before rinsing with water.

Use sanitized gloves, don’t touch the porous surface body of diffusion stone by hands, the oils on fingers can clog the small pores in the stone.
