The peanut roasting machine is widely used for nuts such as peanuts, sesame seeds, walnuts, almonds, and sunflower seeds. Featuring a rotating drum structure and multi-layer hot air circulation technology, the equipment utilizes an intelligent temperature control system that ranges from 0 to 300°C, along with an automatic roasting program that lasts 15 to 30 minutes. This ensures uniform heating and precise moisture control, resulting in crispy, flavorful nuts with consistent color and texture.
Compared to traditional equipment, this machine achieves 15–20% energy savings and 2.3 times higher thermal efficiency. It supports flexible switching between four heat sources: electric heating, gas, fuel oil, or coal. With a maximum capacity of 650 kg/h, it is an ideal choice for modern nut processing enterprises and food factories.
Peanut roasting machine application market

Advantages of peanut roasting machine
- High-efficiency energy-saving design: utilizes a multi-layer hot air circulation system, achieving 10-20% greater energy savings than conventional dryers with significantly enhanced thermal efficiency.
- Intelligent temperature and timing control system: equipped with an automatic thermostat and timer, allowing customizable baking settings for different materials. Features automatic alerts to minimize manual intervention.
- Uniform heating, consistent color: the unique drum-style structure continuously tumbles materials during baking, ensuring even heating, no sticking, and no scorching.
- Stable structure, safe and durable: entirely constructed from food-grade stainless steel, it offers high wear resistance, heat tolerance, extended service life, and superior safety.
- Multiple heating options: choose from electric, gas, oil, or coal heating modes based on production conditions to meet diverse energy requirements.
- High automation: one-touch operation system integrated with light-sensing detection and temperature sensing technology precisely prevents overheating or uneven baking, enhancing product consistency.
- Easy maintenance, low operating costs: rational structure, convenient disassembly, minimal component wear, stable operation, and low maintenance expenses.
Peanut roaster structure and working principle
This machine is mainly composed of frame, stir-frying cage, heating device, and control panel.
The working principle is as follows:
The rotating rolling cage inside the peanut roasting machine continuously rotates left and right, so that the materials in the rotating cage can be uniformly heated. Heating methods are divided into gas heating and electric heating. The material will not directly contact an open fire or heating pipe but use the principle of heat conduction and radiation, take air as a medium and apply heat energy to the baked object.
In addition, in the process of baking, the propulsion device in the rotating cage will continuously push the material forward, forming an uninterrupted cycle, so that the material is heated uniformly, effectively guaranteeing the baking quality. The machine is equipped with an automatic temperature control device, which controls the temperature between 100 and 300 degrees Celsius.
Notes for operation and use
- During the heating process, the rotating cage can not stop rotating to prevent deformation at high temperatures.
- The water content of different varieties of peanuts is different, and the time and temperature required for baking are slightly different. Therefore, every time you change the variety of peanuts or sunflower seeds, you should first roast 1-2 ovens and set the data before mass production.
