The peanut roasting machine is mainly used for roasting or drying groundnuts, walnuts, almonds, beans, coffee beans, melon seeds, beans, and other granular materials and powders.

This machine uses electric heating, oil, gas, or coal as the heat source; it adopts a rotating drum, heat conduction, and heat radiation principles, and uses coal as fuel; the production cost is low, and the machine has the advantages of easy use, high efficiency, energy saving, and durability. The baked products are of good quality, hygienic taste, and can meet export standards.

How the peanut roaster machine works

The working principle of the peanut roasting machine is divided into the following steps:


Raw peanuts are placed at the entrance of the machine and enter the baking chamber through a conveyor belt or other means.


Before the peanuts enter the baking chamber, the machine will preheat briefly. This ensures that the entire system is at the proper temperature for an efficient baking process to begin. Generally set at room temperature 300 degrees.


Raw peanuts are roasted for a certain period in the baking chamber through hot air or radiant heating. The control of temperature and time is very critical to ensure that the peanuts are heated evenly and achieve the desired taste and color.


After baking, the peanuts need to be cooled in the machine. This stage helps stabilize the temperature of the peanuts while ensuring they don’t overheat and affect their quality.


The cooled peanuts finally leave the machine and can be collected by conveyor belts or other systems or entered into subsequent processing stages.
