    • 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.
    • 通过初始加工机器对天然生橡胶进行初始加工,包括以下步骤:(a)提供含有水和挥发性组合物的凝结胶乳; (b)通过螺旋压制法将凝固的胶乳脱水以除去游离水; (c)形成第一预处理胶乳材料; (d)通过老化过程使第一预处理胶乳材料老化以除去水和挥发性组合物; 和(e)形成老化胶乳材料的最终产品。 螺旋挤压工艺利用沿着细长通道结构的温度和压力增加。 老化过程利用橡胶材料的进一步的温度和压力增加,以及螺杆轴部件的拧紧效应,喷嘴的挤压效果和在特定位置附近的附加加热,其位于 喷嘴完成老化过程,这是节能,有效和高效的。
