The main difference between a proofer and a holding cabinet is the operating temperature range. Holding cabinets are designed to maintain temperature of 140F and above, while proofers are designed to hold at 90 to about 110F with humidity. This is important. The proofer typically employs a simple “cal” rod to provide the heat. The heater is in the water tank so it provides both temperature and humidity. While you can operate these without wate, the life of the cal rod is significantly reduced. The heated holding cabinet, on the other hand, does quite well when operated without water. Do keep in mind that you local health department might want to check the temperature in your holding cabinet as part of their routing inspection, if it isn’t as hot as they would like it to be, you may have a problem on your hands it you’re using a proofer (anybody wanna buy a good, slightly used proofer?). I’m here in Manhattan, Kansas, and I can say that one of the top priority things our health department checks for is the holding temperature of anf food item. Coolers, freezers, holding cabinets, self serve food bars (buffets). The reason I know is because we can read about them in the local news paper along with all of their other food safety violations, that’ll get your attention as an owner/operator.
