A vibration unit assembly for a belt conveyor has a vibration element, and vibration generator and a connection assembly. The vibration generator is operatively connected to the vibration element for inducing vibrations in the vibration element. The connection assembly connects the vibration element to the belt conveyor so that the vibration element may move relative to the belt conveyor. A contact surface of the vibration element engages a material to vibrate and compress the material as it is transported on the belt conveyor. The vibration element may include a plate or a roller. A method for treating a material involves applying a vibration force and applying a compressive force to compact the material. A method for drying a material involves applying a vibration force to the material to release fluid and applying a compressive force to compact the material.

A method and apparatus for the continuous sublimation of a substance includes cascading a material containing a substance capable of sublimation, such as water, between a plurality of trays vertically stacked within a processing zone provided within a processing chamber. A substantially atmospheric environment is maintained within the processing zone at a temperature whereby the substance sublimes forming a sublimate within the environment. The environment containing the sublimate is contacted with a drying agent such as a desiccant to maintain the environment whereby the substance sublimes at substantially atmospheric pressure and at the controlled temperature.

An initial processing of natural raw rubber through an initial processing machine, comprising the steps of: (a) providing a coagulated latex which contains water and volatile compositions; (b) dewatering the coagulated latex through a screw-pressing process to remove free water; (c) forming a first pretreated latex material; (d) aging the first pretreated latex material through an aging process to remove water and volatile compositions; and (e) forming a final product of aged latex material. The screw-pressing process makes use of the temperature and pressure increase along the elongated channel structure. The aging process makes use of the further temperature and pressure increase of the rubber materials, together with the screwing effect of the screw-shaft component, the squeezing effect of the nozzle and additional heating at a particular location, which is around the mouthpiece of the nozzle to complete the aging process, which is energy saving, effective and efficient.
