Re: What is this hole for?

I lay a penny on top of the hole. It's useful when you start cooking a batch. When the wash starts boiling, the column is full of air. When the vapor first starts up the column, it pushes the air out (the air doesn't condense). When this happens the penny will dance a little. This is a good indicato...

The slick and bad smell is probably because the corn was too wet. I usually soak the corn for about 24 hours totally covered in water. Then spread the kernels out on a tray lined with a few layers of paper towel. I sprinkle water on the paper towel to keep it moist. The corn is only touching water o...

Water is almost a perfect substance for this. It's nonflammable. It requires a large amount of heat to boil (ie. it transfers a lot of heat without moving a lot of water). It's easy to find and practically free. The downside to water is there's a lower limit on temperature due to freezing. For low t...

I didn't see where you mentioned the diameter of your column. The proper wattage has little to do with the type of wash. The proper wattage should be scaled according to your cross-section area of your column. I run 1500watts on a 50mm diameter column.

Actually you can use any liquid which has a reasonable boiling point. For water you'd have to draw a vacuum so the water will boil at your operating temperature (unless you want to operate at 100C then you'd have water near one atmosphere pressure). If you operate above 100C you need to be sure the ...

I think the resistance of heating elements changes a lot when they heat up. So the resistance you measured when cold probably isn't useful for computing the current draw and power. You didn't mention if your multimeter is a true RMS reading meter. If not then the 252 volts may not be correct. You wa...

You could get rid of all the water and just use cooking oil. Be very careful not to let it get too hot. The cooking oil should be good to 400F. The wash in the boiler should be able to draw out as much power as you put into the oil, but you'll want to keep a thermometer in the oil to be sure you are...

What's the column diameter? I'm guessing it's a 2 inch diameter. 2400 watts is probably too much for a 2 inch diameter column. You'll want the extra power for getting up to boiling temperature, but after the boil starts you'll want 2000 watts or less to avoid flooding. I use 1500 watts on a 2 inch. ...

I'd also recommend using a valved head. The cooling jacket will produce reflux which might tend to flow down the walls of the column and be useless. I'd recommend a head which returns the reflux to the center of the column. I think a coil style condenser is more compact and "tidy". This is just a pe...

On water distillers the cooling water output from the condenser is usually fed to the boiler via some sort of cup with an overflow tube.

You want the column as tall as you can get it. If you are operating indoors this typically limits you to a total height of 8 feet. Your keg will probably be near 2.5 feet tall. The crab cooker is (guessing) about 2 feet tall. The condenser with 1/4 inch coiled tubing can be less than 1 foot long. So...
