CPM Planet Dryers: Side Plenum Conveyor Dryer

CPM Planet Dryers Ltd Two Stage Dryer with Tempering section for cooked corn grits. The Side Plenum Dryer/Roaster machines are designed to process a wide range of food and non- food products. These dryers are extremely versatile and offer a wide range of process dependent features and configurations. DESCRIPTION The Side Plenum machines have been designed to be hygienic using high grade stainless steel. The Side Plenum dryers are modular in construction. This allows for future expansion and makes the machines easy to transport and install with minimal downtimes. The drying chamber is divided into a number of individual zones. Each zone includes an air heater, a circulating fan with an exhaust to control airflow and optimise drying conditions, allowing a counter-flow air system with precise temperature control. The Side Plenum Dryers employ a recirculating air-flow system which provides the necessary drying characteristics to ensure accurate control over moisture levels, temperature uniformity and product consistency in an energy efficient manner. PROCESS Product is fed onto the infeed section and spread across the conveyor bed by a spreader such as a ramshorn, oscillating spreader or a scarf edge conveyor. The conveyor transfers the product through multiple heating zones, consisting of circulating fans which circulate heated air through the product. The air is heated by steam or a gas fired burner with configurable upward or downward airflow. The machines use a controllable recirculating airflow system with a variable exhaust airflow and precise temperature control. Product can then travel through either an ambient air or chilled air cooling section if required. This zone draws in filtered air that has been cooled or chilled. The product then exits through the discharge section of the machine. The conveyor belt speed is controlled by a variable speed drive to allow the required retention time. Zonal temperatures are monitored and controlled by a modulating valve on each burner or heat source. The amount of air recirculating around the system is controlled by the speed of the recirculating fan. For more information please email us at: [email protected]
