Mecmar grain roasters carry out a delicate, homogeneous and rapid treatment on any type of cereal (soy, beans, field beans, sorghum, corn, etc.), in order to adapt to various needs and always guarantee quality and efficiency.
The product to treat is loaded into the hopper and is dosed inside the roaster through a star valve. The conveyor belt gently accompanies the grains from the entrance to the machine outlet: during this process, the cereal is treated homogeneously by a flow of hot air which passes through a perforated bed, roasting the cereal. Depending on the needs, the heat can be supplied by oil, gas or LPG burners or by a heat exchanger.
To increase efficiency and decrease energy consumption, the hot air leaving the machine is recovered to preheat the air used for roasting. The roasting process is automated thanks to the use of inverters and controlled by a network of sensors that allow to optimize the roasting process and to intervene in complete safety even in case of emergency.
