Chill Tea or Supplies Quickly With This DIY Submersible Chiller

The submersible chiller quickly cools hot liquids by passing cold water through a spiral copper tube immersed in the liquid. You can make this model with your own hands in any size that suits you.

If you are preparing large batches of broth, pickle, or tea, you know how long it will take to cool before you put it in the refrigerator. Do not refrigerate it while it is hot, because so much hot liquid can raise the temperature inside. And you don’t want to leave the stock on long enough to cool down first, because you don’t want to stimulate bacterial growth.

The submersible chiller cools a gallon of liquid in just a few minutes. Assembly requires some effort. You will need to heat the pipe (a kind of copper pipe designed for plumbing) with a propane torch or other heat source to be flexible enough to bend. Then you wrap the tubing in a spiral around a shape (such as a paint can) of the size you want. When the coil is ready, you simply attach the hoses and it is ready to use.

You can buy submersible chillers designed for brewers, but they tend to be quite large, usually sized for a 5 gallon bucket. If you do it yourself, you can make it exactly the size you need to fit in your favorite pot and use it right in the kitchen. And if you’re worried about wasting water, just collect it at the other end and use it for whatever you want. It only comes into contact with the inside of the clean copper pipe.
