      Product Description

      Our Rapidflow Linear Oven and Industrial Air Fryer is one of our most versatile cooking solutions. While our linear ovens have evolved over the years, the latest model still features the structural durability of an independent inner skin design and extraction system for high-temperature browning applications and multiple independently controlled zones for optimal cooking. With high-velocity airflow at the heart of its process, the Rapidflow offers multidirectional and variable speed fans which enable operation in impingement mode with high velocity airflow or in convection mode, to envelope irregularly shaped products with uniform energy. Air passes through the heat exchanger and is then applied to the cook zone in forward, reversing, or combination patterns to create a perfect thermal atmosphere for rapid, uniform cooking or browning of any product. Recipe controls include temperature, water vapor, residence time, fan speed, and extraction rate, to provide users maximum flexibility and complete control of finished product appearance, texture, and flavor. The Rapidflow is used to process a wide range of products around the world, from crispy golden-brown whole deli turkeys to uniformly browned meat pies. Additionally, the oven’s versatile airflow pattern optimizes rapid and uniform cooking for ready meal components like meatballs, chicken drumsticks, and vegetables.

      Industrial Air Frying: Marlen’s Rapidflow Linear Oven is a perfectly adapted industrial solution that simulates a deep fried product without submerging the product in oil. The impingement air movement within this linear oven circulates hot air at high speed upon the product producing a crispy brown result. An oxygen sensor is integrated with the Oven’s Steam Overheat Protection System designed to reduce the risk of fire and suppress the flash point of the oil. This allows this Industrial Air fryer to operate at higher operating temperatures resulting is faster cooking times. Additionally, accessories such as an air fryer oil applicator, product flip, and exhaust duct fat separator optimize the air frying process.
