The latest update to the Litchfield equipment is a RollSeal door that has been installed on the large batch oven. We replaced the old metal double-door with this “garage” type RollSeal door and have been impressed with the improvements.
This is a unique improvement that AFI hasn’t tried in the past, but has a few advantages. The first advantage is that this door seals the oven much better than the conventional doors. The pliable fabric of the RollSeal is pushed against the oven door frame by the pressure inside of the oven. This covers all of the small cracks in the frame creating a better seal. The improved seal not only saves us money on the gas bill, but also helps keep the temperature more even throughout the oven. This allows us to feel confident that especially long parts are being baked evenly. The second big advantage is that the door can be opened and closed remotely, just like a garage door. This advantage allows the operator to stay on the fork lift and moving the load around while the door is opening. It also reduces the amount of time that the door is open letting heat escape because the operator isn’t spending time jumping on and off the forklift.
We will continue to look for opportunities in the future, big or small, to improve our process and equipment!
