本发明涉及一种用于松散材料短时间热处理和/或淬火的方法和装置，并且其可用于化工、食品、木器加工和其它工业。松散材料的脉冲热处理方法包括以下步骤：蒸发表面湿气；快速加热到所需温度并随后通过将颗粒进给到其温度超过100℃的旋转表面上进行冷却，其中在离心力的作用下颗粒与加热表面接触，接触时间和压力通过改变旋转速度来控制；并且颗粒淬火步骤在冷却器表面上通过快速冷却进行，并且收集成品到蓄料器内。移动的松散材料颗粒的处理在可旋转圆柱形和圆锥形热表面上进行，其上过量湿气蒸发步骤和加热到所述温度的步骤结合在一起。材料在重力的作用下沿加热表面的移动时间通过摩擦力控制，摩擦力通过改变旋转速度控制。还公开了一种用于实施所述方法的装置。
The present invention relates to a short heat treatment of bulk material and / or a method and apparatus for quenching, and which can be used in the chemical, food, wood processing and other industries. The method of pulse heat treatment of bulk materials comprising the steps of: evaporating surface moisture; rapidly heated to the desired temperature and then cooled by feeding the particles to a temperature which exceeds 100 ℃ surface of revolution, in which the particles are heated under a centrifugal force surface contact, the contact time and pressure controlled by changing the rotational speed; and particles quenched by rapid cooling step is carried out on the surface of the cooler, and collected into the storage hopper finished. Mobile handling loose material particles on a rotatable cylindrical and conical surface of the heat, which the excess moisture evaporating step and the heating step to the temperature together. Material under gravity along the surface of the heating time by frictional movement control, the frictional force is controlled by varying the rotational speed. Also disclosed is a device for carrying out the method.
