The series HTK for continuous operation is ideally suited for high throughput,the series HTC has its optimal application in variable processes and frequent product change. Both types are well suited for homogenising, preparation of solids blends, solid-liquid mixtures up to pastes and slurries and for gentle drying.
In case of the dryers the product is moved along the heated wall of the drum.The bulk blending activity results in a uniform temperature and humidity of the product in the process area. Specially formed paddles guarantee an optimal heat exchange between product and the wall of the drum. The result are short drying times that can be further reduced by operation in reduced pressure.
