The factors affecting the roasting quality of peanut roaster machine

Peanut roaster machine is easy to use, efficient and energy-saving, resistant to high temperature, erosion, high thermal efficiency, movable, easy to maintain and widely used. Its structure is relatively simple, cleaning is convenient, and the roasted products are of good quality, hygiene and good taste. Peanut roaster machine is widely favored by investors because of its many advantages.

In the process of using the equipment, what are the factors that affect the roasting quality of peanut roaster machine?

First, the quality of the machine.

Choosing a reliable peanut roasting machine is the key factor to determine the quality of peanut roasting. The peanut roaster machine with stronger heat source can generate enough heat energy, so that the temperature of peanuts can rise rapidly at the beginning of roasting, which is very important for the formation of peanut flavor. Whether the design of peanut roaster machine is reasonable or not directly affects the taste, color and maturity of roasted peanuts.

Second, the situation of peanuts.

Peanut variety, peanut density, humidity and shape will all affect the absorption of heat. Only by knowing the density, water content, shape and size of peanuts can we reasonably calculate the energy required for roasting these peanuts, and then set the roasting amount more accurately through sample roasting to ensure the roasting effect in the final roasting.

Third, the temperature.

Temperature is the main factor affecting the roasting speed. With the increase of temperature, the water pressure in peanuts increases, which is beneficial to promote the flow and diffusion of water in peanuts. The moisture solubility of the medium is improved, and the evaporation rate of water on peanut surface is accelerated. The optimum roasting temperature of peanuts is about 200 degrees, but the discoloration and coking of peanuts caused by too high temperature should be prevented.

Fourth, the relative humidity.

Relative humidity is an important factor affecting roasting speed. Under the condition of the same temperature and air velocity, the higher the relative humidity, the greater the partial pressure of water vapor in the medium, the less easy it is for the water on the surface of peanuts to evaporate into the medium, and the slower the roasting speed; When the relative humidity is low, the surface moisture evaporates quickly and the roasting speed is fast. However, we should also pay attention to the fact that the lower the relative humidity is, the better. If the humidity is too low, the roasting defects such as cracking and honeycomb will occur.

Fifth, air circulation speed.

The air circulation speed is another factor that affects the roasting speed. High-speed airflow can destroy the saturated steam boundary layer on the surface of peanuts, thus improving the heat and mass transfer conditions between the medium and peanuts and accelerating the roasting speed.

To roast high-quality peanuts, it is necessary to choose a reliable peanut roasting machine. However, in addition to a good equipment, other key points that affect the quality of peanut roasting should also be done in place in order to finally roast high-quality peanuts.
