Ways to upgrade your industrial batch ovens for improved performance
With routine maintenance, industrial ovens can run flawlessly for years, but sometimes, even the sturdiest equipment eventually needs replacing or refurbishing. A common question in our line of work is “Should we replace our old equipment with a new oven? Or is it more beneficial to repair, refit, or rebuild our current equipment?”.
Budgeting for capital expenses cannot be made without considering the financial & production implications the cost and downtime that replacing equipment can incur.
It is common for industrial batch ovens to be remodelled and improved in accordance with new specification and parameters required.
There are a few ways to upgrade your industrial batch oven’s performance, and we’ve mentioned a few key variables below:
Improve the Temperature Uniformity
A modified oven design will ensure that the heated and recirculated air is properly circulated, improving temperature uniformity. To make sure the air exiting supply ducts is circulated properly, experts at DRYSYS will analyse the oven’s airflow and design the appropriate upgrades for temperature uniformity.
Increase Heating Capacity
One of the biggest design problems is the oven’s heat capacity. A change in a product or process may lead to an increased heat-load. Sometimes, this can be done simply by increasing the heaters output. Other times, however, a new burner or additional heater banks are required.
DRYSYS’ extensive expertise includes redesigning ovens for increased heat output as well as correcting deficiencies in the original oven design, specifications, and manufacturing.
Decrease Part Ramp-Up Time
An oven is commonly thought of as an energy transmission device. However, one effective technique to reduce part ramp-up times is to increase the velocity and volume of air that circulates through the oven chamber, warming up the parts.
It is important that the recirculation system, as well as the supply and return ducts, are well designed, so all surfaces of the product processed in the industrial oven are exposed to fast moving air, and that this air recirculates through the heat source.
Often, the size and length of recirculation ductwork do not match with the static pressure capacity of the recirculation fan in the original design of an industrial oven.
Upgrades to Oven Shell Construction
Some industrial ovens are built with a casing that isn’t strong enough for the equipment’s projected life cycle. This is frequently caused by original manufacturers’ efforts to cut costs in the shell’s construction by reducing the material thickness, number of welds or fasteners.
Manufacturers may fail to allow for ovens expansion and contraction requirements. A corroded or stressed shell is another factor that contributes to the early fatigue of industrial ovens. A galvanised panel, for example, can rust prematurely if exposed to certain chemicals, as opposed to aluminised or stainless steel.
Size, conveyor speeds, and material handling are an integral part of industrial ovens.
