Table 3 and Table 4 show the mass calculations for each ingredient. This table was

formulated using each ingredient density value from Table 1 along with the total mass in the

system calculated for Screw Design 1 and Screw Design from Table 2. Doing this for the two

assumed screw size ranges can give estimated value for the maximum mass that will be pushed

through the auger screw at any given time. The maximum mass found based on the rudimentary

designs is .6256 pounds for our critical ingredient, brown sugar. This is the load the screw will

have to constantly push at varied rates to output the critical ingredient. This information will help

determine a torque requirement for the motors.
