J&S Laser Profiles were approached by a client who required a replacement for one of his two charcoal burners which was beginning to deteriorate. The client wanted the new machine to operate with the same type of burning system, which is known as a retort, but the new machine needed to be more durable and longer lasting than his original. With this in mind we designed and manufactured a similar burner to his existing but made the new one completely from stainless steel with thicker gauges and added stiffeners to help to prevent distortion and increase longevity.
This type of charcoal burner is known as a Retort, it’s believed to be more efficient than conventional methods cleaner and more user friendly, they can also be adapted for trailer mobility.
A brief description of the Retort method is that before operation the inner cylinder is loaded with the cut logs and when full the door is closed and sealed, underneath this inner cylinder and between the outer cylinder a fire is lit, this heats and cooks the logs inside the inner cylinder, the outer cylinder then has its door sealed and closed. During the cooking operation of the logs inside the inner cylinder gas is produced this gas is diverted by simple flap valves and ducting in the outlet chimneys back to the fire which increases the heat considerably, the internal heat is monitored by a sensor and adjusted to maintain the required temperature, this is done by adjusting the gas in and out through the flap valves any excess gas is expelled and burnt off out of the chimneys fitted to the cylinders.
When the required cooking time is completed and the retort has cooled the doors are opened and the charcoal removed and bagged.
This replacement burner has been manufactured from Stainless steel grade 304 instead of the originals mild steel and with considerations given to areas that were susceptible to distortion by using thicker stainless steel and adding extra supporting webs.
The overall complete retort including stand weighs in at approximately 3 tonnes.
