HESHAN® peanut roasting production line is an automated, continuous processing system designed to uniformly roast, cool, season, and process peanuts at scale. Capacities typically range from 100 kg/h to 1,000 kg/h or more, offering large-scale snack and butter production lines.
The Heshan seasoned peanut roasting production line uses a process of spraying seasoning liquid and coating powder to combine syrup, peanuts, and mixed powder. This is followed by a continuous roasting process, which matures the peanut and reduces their moisture content to around 3%, resulting in crispy and tasty seasoned peanut. The production line is fully automated, ensuring high production efficiency, uniform coating, stable roasting temperature, and finished products that meet European and American standards. The roasting production line is CE certified.
Production Line Process Flow
Production Line Process Flow
An automatic peanut roasting line involves several linked machines. The specific steps vary based on the desired end-product, such as dry-roasted snack peanuts or base material for peanut butter.
The peanut roasting machine is a new type of multifunctional roasting (drying) machine for peanuts, grains, and nuts. Its advantages include a high degree of automation, automatic temperature regulation, and multiple heating methods, such as electric heating and gas heating. By using a circulating fan to exchange heat, it achieves strong airflow roasting, enhancing both roasting efficiency and quality. The machine has a cooling zone at the end, allowing for integrated roasting and cooling in a compact structure. It can process various granular foods, including five-spice peanuts, milky peanuts, sesame-coated peanuts, almonds, cashews, and buckwheat.
Feeding & Elevating: Raw peanuts are loaded into hoppers and fed into the roaster using automated bucket or pneumatic elevators.
Roasting: Peanuts pass through a roasting machine (electric or gas-fired) with continuous temperature controls from 0°C to 300°C.
Cooling: Roasted peanuts drop into a cooling belt, utilizing high-pressure fans to reduce the core temperature of the nuts.
Peeling (Optional): If making peanut butter or peeled roasted nuts, the cooled peanuts are passed through a peeling or skin-removing machine.
Seasoning & Coating (Optional): Automatic seasoning machines tumble the peanuts with flavoring liquids or spices to create products like roasted salted peanuts.
Packaging: Finished peanuts are packaged into containers using automated weighers and fillers.
