Abstract

One of the first steps in the beer brewing process is to heat water to a specific temperature before it is mixed with the malt. The purpose of this project was to make a more compact and efficient heating device for the beer brewing process. The output temperature must be between 170⁰F and 180⁰F. The minimum flow rate should be half a gallon per minute with the maximum flow rate of three gallons per minute. The device will also need to mount to a collapsible beer rack being designed by Andrew Kastning. The device will be primarily compromised of two 2 inch steel square tubes welded forming an L shape, a burner, coiled copper pipe and a cover made of stove pipe for the coils that will be mounted to the L shape welded steel square tubes and above the burner. Analysis was completed to determine the optimal size of copper tubing to most efficiently heat the water. Three-eighth inch copper pipe was selected for the coil. Upon testing the device the flow rate was able to be dialed down between one half and three gallons per minute while staying in between the desired temperature range of 170⁰F and 180⁰F.
