The Starch Mogul Machine can withstand temperatures up to 150 degrees Fahrenheit. The syrup hopper and the silicone sprays are made of stainless steel, which can withstand high temperatures. The machine is designed for a climate-controlled environment, with a recommended temperature of 68-77 degrees Fahrenheit. If you’re planning to use the machine in an area where the temperature outside is very hot or cold, it’s best to keep it in a climate-controlled room or inside your home where it will be protected from extreme weather conditions.
