I created a yeast bio-reactor consisting of 4 main parts. The first part is the feeder, the blue unit, which will hold the nutrients within the. Below are multiple red units that will allow the first fermenting stage to occur. The middle part is the heater that keep the red units at the appropriate temperature for the yeast. The red unit also has filters at the bottom that can be opened when filtration into the second fermenter is needed The last unit is where the final fermentation stage will occur. This unit has a heating element underneath. It also has rods in the middle to keep water contained and also to feed the yeast.
