Peanut Roasting Machine Heating Methods: Electric, Gas, Hot Air & Infrared Compared

In the process of peanut processing, roasting is a crucial link, which not only affects the flavor of peanuts, but also directly affects the quality and market competitiveness of products. As the key equipment to realize this process, the heating methods of peanut roasting machine is particularly important.

At present, the heating methods of peanut roasting machine are mainly divided into the following types:

Electric Heating Peanut Roasting Machine

Electric heating is a common and environmentally friendly heating method. Heat is generated by resistance wires or electric heating plates, and the temperature can be accurately controlled by electric heating, which is suitable for occasions with high requirements on roasting temperature. In addition, the electric heating equipment has simple structure and convenient maintenance, but its operating cost is high, which is suitable for small and medium-sized processing plants.

Gas Heating Peanut Roasting Machine

Gas heating uses natural gas, liquefied petroleum gas, etc. as fuel, and generates heat through combustion to heat peanuts. This method has the characteristics of high heating speed and high thermal efficiency, and can meet the needs of large-scale production lines. However, because gas equipment needs to be equipped with special pipelines and safety measures, its initial investment cost is high. In addition, the gas heating mode has certain requirements for fuel quality and supply stability.

Hot Air Circulation Roasting Technology

Hot air circulation heating is an advanced heating method, which blows hot air evenly into the peanut roasting machine through a circulating fan, so that peanuts are heated more evenly. This method can not only effectively reduce the roasting time, but also ensure that the surface and interior of peanuts can reach the ideal roasting degree. Hot air circulation heating is usually combined with electricity or gas as heat source, which is a more efficient and energy-saving choice at present.

Infrared Heating Peanut Roasting Machine

Infrared heating uses infrared radiation to directly act on the surface of peanuts, which makes them heat up rapidly. This way can reduce heat loss, improve energy utilization rate, and make peanut roasting more uniform. However, infrared heating equipment is usually expensive and suitable for processing scenes with high requirements on product quality.

Different heating methods have their own advantages and disadvantages. Enterprises should comprehensively consider their own production scale, cost budget and product demand when choosing peanut roaser machines. With the development of science and technology, heating technology is also improving. It is believed that more innovative heating methods will be applied to peanut roasting in the future, bringing consumers a better product experience.
