Provided is a paddle processor and a method for processing material within the paddle processor. In one example, the paddle processor may include a trough comprising an inlet to receive a feed of material and an outlet for exiting the material after processing, rotational paddles disposed in the trough and configured to rotate about each other to move the material from the inlet to the outlet, an overflow weir disposed in association with the outlet and having a dynamically adjustable height for controlling a rate at which the material exits the trough, and a control system configured to dynamically adjust the height of the overflow weir and/or other dryer parameters based on a temperature of the material within the trough.

A process and apparatus for removing moisture from sludge. The process and apparatus comprise: conveying on a conveyor the sludge on an incline through a housing such that, as the sludge is conveyed, it is deposited onto an exposed portion of the housing; heating the sludge with a heater as it is conveyed on the incline to evaporate moisture in the sludge, whereby the sludge that it is deposited onto the exposed portion of the housing is also heated to thereby evaporate moisture from the sludge; extracting from the housing using a vacuum device an airflow comprising the evaporated moisture, whereby the airflow includes moisture that has been evaporated as a result of the sludge being deposited onto the exposed heated portion of the housing; and discharging from the housing, separately to the extracting of the airflow from the housing, the sludge from which the moisture has been removed.

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.
