Abstract: A centrifugal separator, such as a spin dryer that separates water from wet clothing includes a stationary chamber. A perforated basket is arranged to spin within the stationary chamber. A DC or AC motor is arranged below the bottom floor fastened to a mechanical floor. A driveshaft can be connected to the motor output shaft via a flexible coupling and passes through the bottom floor and is connected to the basket. A brake disc is operatively fixed to the output shaft, and a brake caliper is fixed to the mechanical floor to stop the brake disc. A balance ring, having an annular chamber holding a balance fluid, is mounted to an outside of the basket. The centrifugal separator can include a cycle controller that can ramp up or down the basket speed and reverse spinning direction of the basket.

Abstract: An improved spin dryer having an improved braking system, vibration absorbing suspension system, and automatic power shut off system. This spin dryer is safe, inexpensive, and substantially free from vibration and noise. The spin dryer of this invention also contains a spin compartment which will stop spinning typically upon a slight upward movement of the lid and spin once again upon the release of a small downward press on the dryer lid.
