A peanut roasting machine is an essential piece of equipment for peanut processing. It uses controlled heat to roast raw peanuts evenly, improving their flavor, aroma, color, and texture. Roasting is an important step in the production of peanut butter, roasted peanuts, peanut snacks, peanut powder, and other peanut products.
Depending on production capacity and processing requirements, peanut processors can choose different roasting systems. The two common types are the rotary drum peanut roaster and the continuous chain roasting and cooling machine.
The rotary drum peanut roaster is suitable for small and medium-scale peanut processing, while the continuous chain roasting and cooling machine is designed for large-scale and continuous production.
What Is a Peanut Roasting Machine?
A peanut roasting machine is a food processing machine designed to roast peanuts at a controlled temperature. During the roasting process, raw peanuts are heated evenly until they reach the required moisture content, color, aroma, and taste.
Compared with traditional manual roasting, a commercial peanut roaster provides:
More uniform roasting
Accurate temperature control
Higher production efficiency
Lower labor requirements
Better product consistency
Cleaner and more hygienic processing
Easy integration into peanut processing lines
The roasted peanuts can then be cooled and sent to the next processing stage, such as peeling, grinding, seasoning, packaging, or peanut butter production.
Types of Peanut Roasting Machines
Our peanut roasting equipment mainly includes two solutions:
Rotary Drum Peanut Roaster
Continuous Chain Roasting and Cooling Machine
Both machines can provide efficient and uniform roasting, but they are designed for different production requirements.
Peanut roasting machine
Type 1: rotary drum peanut roaster
Thispeanuts roasting machine is mainly used for baking peanut kernels. It adopts the advanced structure of the drum, which is cutting-edge technology. The heating source can be electricity or gas. A thermostat is installed to adjust the temperature.
The temperature can reach 240-260 Celsius degrees in an electricity-heated roaster, 220-240 in a gas-heated model. The roasting time can be set.
Working Principle
Put raw materials into the inlet, and the drum rotates continuously. In the process, roasted food moves up and down, left and right, back and forth, and is fully stereoscopic. Thus, the drum roasting machine heats peanuts uniformly.
When the time is up, the peanut roaster machine discharges roasted nuts. This machine is applied in baking peanuts, almonds, sesame, and other nuts.

| Gas consumption (kg) | 2-3 | 3-6 | 6-9 | 9-12 | 12-15 |
Type 2: continuous chain roasting and cooling machine
A continuous chain roasting machine is widely used to process peanuts, cashews, walnuts, pistachios, almonds, broad beans, and other granular nuts. The equipment heats the materials evenly and efficiently. It can realize continuous feeding and discharge with high efficiency.
The baking temperature and time are both controllable. Equipped with a circulating air device, the machine cools the roasted material after roasting. The machine capacity ranges from 100kg/h to 1ton/h. Its heating source can be gas or electricity.The process from infeed to discharge takes just half an hour; the baking zone operates at 140–180°C, and the product temperature upon exit is 10°C above ambient. This integrated chain-plate baking and cooling machine features high air pressure and delivers superior baking quality.

Peanut Roasting Machine for Peanut Butter Production
For peanut butter manufacturers, roasting quality directly influences the flavor and quality of the final product.
A typical peanut butter production process is:
Peanut Cleaning → Roasting → Cooling → Peanut Peeling → Sorting → Grinding → Mixing → Filling → Packaging
The rotary drum peanut roaster is suitable for smaller peanut butter production projects, while the continuous chain roasting and cooling machine is more suitable for larger automated production lines.
By combining the peanut roaster with peanut peeling and grinding equipment, manufacturers can establish an efficient peanut butter processing line.
