Abstract
A cooler for mixtures of crystals and crystallizing liquid in the production of sugar and related products comprises a bundle of vertical pipes for the passage of such a mixture from a bottom chamber to a top chamber. The vertical pipes are surrounded by a cooling medium, and in the interior of the pipes plungers are provided which have a somewhat smaller diameter than the inner wall of the pipes so as to form a slot-like passage along the inner wall of each pipe. The plungers are moved up and down through the pipes. The cooler is especially adapted for promoting crystallization by a rapid drop of temperature.
