The Duravant family of operating companies serve the food processing, packaging and material handling segments.

What Does Marlen Mean When We Say High Performance Industrial Oven?


It’s important that thermal processing technology such as high performance industrial food processing ovens and smokehouses deliver uniformity and efficiency for quality, uniform product. Robust sanitary construction and an efficient mechanical design, including fans, ducts, air plenum and alternating dampers working together to enhance airflow are major factors in achieving consistent processing conditions for precise repeatable results, day after day.

Reliable Industrial Ovens and Smokehouses with Uniform Processing Conditions Necessary for High Quality Cooked or Smoked Meats

Permanent air balance of supply and return air results in full control of the all-important “breakpoint” – the physical point at which the high velocity air mass collides with the low velocity air mass. Marlen’s permanently balanced system ensures that the breakpoint stays where it is supposed to be which is essential for repeatable process and quality, uniform product. When Marlen designed its industrial oven and smokehouse, a programmable encoder was a key feature to enable control (pause, stop or accelerate) over rotating dampers for precise control of breakpoint. Errant movement of the breakpoint can result in product that varies in weight, appearance, and internal temperature so programmable controls is a must. Breakpoint is everything. We suggest seeking more information related to optimizing oven process repeatability to ensure you source an oven that contributes to and delivers optimal repeatability.

Ease of Operation and Maintenance is Key in High Performance Industrial Ovens and Smokehouses

Efficient air handling systems eliminate the need for balancing or adjustment of any kind while control is made easy with Powis Corporation technology, the most responsive and intelligent computer control system in the industry. An ‘Auto-Report’ feature collects, and emails completed cook-cycle data so that plant management can stay in the loop, even when they are not in the plant. This helps when following HACCP guidelines required for manufacturing finished food products. Maintaining a food processing oven should not have to involve shutting down operations or performing gymnastics to reach serviceable areas. Marlen’s ovens and smokehouses feature a generous service access area enables change-out of wet bulb wicks while the oven is loaded with product. This all equates to easier operation and maintenance.

High Performance Industrial Ovens Consume Less Energy

Marlen batch ovens and smokehouses feature a unique design that requires 20-25% less horsepower to deliver the same air flow as other single fan ovens and up to 50% less horsepower than multi-fan ovens. Efficient management of process air ensures that product and process dictate energy consumption.

Custom Designed Industrial Ovens and Smokehouses for Unique Food Products

Every Marlen processing oven is custom designed with the food processor’s operational and application needs in mind to gain a full understanding of the oven’s key components that contribute to and delivery optimal repeatability. Internally and externally, every facet of every Marlen oven outperforms the competition. Energy saving heating and air handling system, permanent factory air balance, sanitary monolithic floor and pitched roof as well as precision process controls all add up to the lowest possible cost of ownership all while achieving the highest food product quality. It’s the company behind the machine that makes the difference. Marlen is recognized as a global manufacturer of highly engineered food processing equipment and systems.
