CheesemakingOver the past several years, I have become quite interested in cheesemaking as a hobby and have made a wide range of cheeses, both soft and hard. I am the founder and president emeritus of Queso Diego - San Diego's Cheese Club.
My Cheesemaking SystemFor aging cheeses, I made a cheese cave from a 4.4 cu ft mini fridge. Temperature is controlled using an external digital controller. Humidity is contrlled with an external controller and a small ultrasonic humidifer.
For smaller batches, I usually just use a couple large pots on the stove as a 2-4 gallon double boiler.
For larger batches, I use a homemade electric cheesemaking system that also doubles as my homebrew system. It consists of a 15.5 gallon heated outer pot made from a converted sanke keg and a 5-7.5 gallon inner pot (interchangeable), along with a March pump and control box.
The outer pot has 2 electric water heater elements mounted into it, providing a combined 3500 watts of heating power. For recirculation, it has a stainless ball valve with camlock quick disconnects. A March pump (with quick disconnects) is used to pump water from the bottom of the pot to a recirculating arm near the top, creating a whirlpool around the inner pot to maintain even temperatures. A RTD thermocouple is mounted into the pot as part of the temperature control system. A thermometer and sight glass are included for convenience.
The control system is a custom-designed PID control box that I built, which controls 2 separate 120V circuits that power the heating elements. An Auber auto-tuning PID is used to control the temperature by duty-cycling power to the heating elements in the outer pot based on the reading from the RTD probe. A switched auxiliary outlet is provided on the control box for easy control of the March pump and any other accessories.
When I use it, I can simply dial in the temperature I want on the PID controller and the outer pot will hit that temperature and hold it. I can ramp up the temperature as needed. With the 5 gallon inner pot, the usable capacity is about 4 gallons; with the 7.5 gallon pot, 6+ gallons should be possible. A future upgrade will be to switch to a PID with the ramp/soak feature, which will allow me to program in the temperature steps and ramps for the entire cheesemaking session at the start.
