Abstract

See full text

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.
