Повышение эффективности процесса сушки зерна за счет модернизации сушильных камер

Abstract

The authors consider the stage of grain drying as part of a technological process for obtaining biodiesel fuel. The drying process is associated with a number of disadvantages that affect the quality and cost of biodiesel fuel. One of them consists in the difficulty of uniform heating and maintaining the desired temperature under minimal energy costs. Following a review of international experience in this field, the authors propose a method for modernizing the existing systems of grain heating. Mathematical calculations were carried out to determine variations in the temperature field versus time; full-scale experiments were performed to identify the optimal number of heating sources, taking the drying chamber dimensions into account. The proposed engineering solution makes it possible to form a uniform temperature field, thereby providing for uniform grain heating and preventing high operational costs associated with oil leakage from the grains.
