Rotary Cooker

Rotary Cooker About

RCN STEAM ROASTING / COOKING PROCESS:

• Capacity: As per customer requirements
• Example Capacities: 300 / 600 / 1000 / 1200 kg per batch cooker capacity
• Fuel: Steam from boiler through Non-IBR piping and fittings

APPLICATION & PROCESS:

• Graded RCN gunny bags are fed into a ground-level hopper in the pit and transferred through a vertical conveyor to the water washing system. This process eliminates large stones, metals, scraps, and other impurities.
• The washed RCN is directly transferred to a vibro-mechanism with fan mounting to drain excess water.

Important Note:

RCN must be cooked within 1 hour after water washing; otherwise, the kernel quality may be affected.

• Cashew steaming / roasting helps to cut, break, and separate the shell and kernel easily by making the outer shell hard and brittle.
• After steaming, the nuts are air-cured by spreading them on the floor in shade, gunny bags, curing trolleys, or curing vertical bins. Vertical curing bins can be customized based on project requirements.
• System capacities can vary from 4 MT RCN to 50 MT RCN depending on project requirements.

FULLY AUTOMATIC LOCUS COOKER OPERATIONS CONSIST OF THE FOLLOWING FEATURES:

• This fully automated RCN cooking system is entirely controlled by a Programmable Logic Controller (PLC) panel. It features automatic cut-off weighing, automatic start and stop steam flow, and all doors are pneumatically operated.
• The RCN, originating from a Vibro-mechanism output, is directly fed into a hopper and a vertical conveyor that transfers RCN to an overhead hooper situated above the cooker. The overhead hooper is equipped with a load cell that monitors the RCN load. Upon reaching the desired capacity, the PLC panel initiates the stopping of the entire backward feeding line, comprising the vertical conveyor, Vibro-mechanism, and the autoloading destoner washing system. This action effectively eliminates any contact between RCN and water.
• In the RCN cooking process, steam input is automatically controlled by a timer input provided in the PLC panel.
• All three doors, the overhead hooper output, the cooker input, and the cooker output are pneumatically controlled, eliminating the need for manual intervention.
• Upon the completion of the cooking cycle, the cooked RCN is transferred to a hopper, which is subsequently conveyed on a vibratory mechanism comprising perforated sheets to remove excess moisture and a cooling fan to reduce the temperature of the cooked RCN.
• Subsequently, the cooked RCN is fed into the hopper and a vertical conveyor through which transports it into curing bins where it undergoes curing for the remainder of the day.  Pneumatically operated conveyor outlet doors to select desired section of partition.
• LOCUS cooker design achieves more than 95% efficiency for uniform cooking throughout the batch, improving the quality and performance of downstream machinery stages.
