Manual charring machine for barrels from 53 gallons up to 132 gallons. Electronic ignition pilot with safety valve. Manual carriage with gas burner approximately 40". The barrel is manually loaded onto rollers. The barrel is turned during the charring session using four drive wheels and has a VDF to determine the speed of the turning. The ignition switch moves in and out. When it is ready to char, it moves in closer to the barrel and then chars based on the program you determined. It does need the metal piece to protect the croze. MIT recommends keeping the head on one end while charring. You can use either natural gas or propane, we just needs to know which you prefer.The charring timing is programmable. The intensity of the gas and oxygen of the flame inside the barrel is manually regulated. Will process approximately 5-8 barrels per hour.
