Reducing the rate of broken rice and increasing the rate of whole rice have become a way to improve the comprehensive economic benefits of enterprises. The higher the temperature of the rice mill is, the more broken rice is produced. This is a common phenomenon in rice factories. In the process of rice milling, the sand roller grinds the surface of the rice grain to remove the crust layer and the rice grains in the whitening chamber are subjected to friction and collision, which will generate a large amount of heat, so that the surface temperature of the rice grain is increased.
Due to the poor thermal conductivity of the rice grains and the slower inward transfer of the surface temperature of the rice grains, a temperature gradient (temperature difference) is formed from the outside to the inside. A large temperature difference causes thermal stress to be generated inside the rice grains, and the thermal stress exceeds the inherent strength of the rice grains. The rice ruptures or bursts. The structure of the traditional rice machine determines that the rice machine has a large ventilation resistance, and the air volume passing through is small, and it is difficult to suppress the rice temperature from rising during the rice milling process to produce broken rice. Achieving low-temperature rice milling and inhibiting the rise of rice temperature is an effective method to reduce cockroaches.
Durch Erhöhung der Luftmenge, die in die Weißkammer eindringt, ist es möglich, den Temperaturanstieg zu senken und die Reismenge zu erhöhen. Niedertemperatur-Reis ist die Verwendung des in die Weißkammer gesprühten Winds, um durch die Reisschicht zu strömen und die beim Mahlen erzeugte Wärme abzutransportieren, um den Anstieg der Reistemperatur zu unterdrücken. Daher besteht die Schlüsseltechnologie der Niedertemperatur-Reismühle darin, den Luftdruck und das Luftvolumen des integrierten Gebläses der Reismühle zu erhöhen, den Widerstand des Winds, der in den vorderen Teil der Weißkammer gesprüht wird, zu verringern und die Belüftungsmenge des beweglichen Weißbereichs pro Produktionseinheit zu erhöhen.
