    • A raw material (11), which is formed of a cellulose acylate and an additive, is placed in a hopper (20). The pellet raw material (11) is supplied from the hopper (20) to an extruder (12), melted therein and extruded as a strand (21) in a water vessel (13) to cool the strand (21). The strand (21) is then fed into a cutting unit (14). Washing water is supplied from a water supply unit (31) to a cutting section (14a) of the cutting unit (14). The strand (21) is cut into pellets by the cutting section (14a) and the generated powder is recovered by a powder separation unit (32). After the pellets are separated by a pellet/water separation unit (35), they are fed to a sieve unit (16) to further remove powder by the sieve (18). The pellets (23) from which the powder is removed is fed to a vessel (17) and stored as a pellet aggregate (24).
    • 将由纤维素酰化物和添加剂形成的原料(11)放入料斗(20)中。 颗粒原料(11)从料斗(20)供给到挤出机(12)中,在其中熔化并在水槽(13)中作为股线(21)挤出,以冷却线材(21)。 股线(21)然后被送入切割单元(14)。 洗涤水从供水单元(31)供应到切割单元(14)的切割部分(14a)。 通过切割部分(14a)将股线(21)切割成颗粒,并通过粉末分离单元(32)回收生成的粉末。 通过颗粒/水分离单元(35)分离出颗粒后,将它们进料到筛单元(16),以进一步通过筛子(18)除去粉末。 将去除粉末的颗粒(23)进料到容器(17)中并作为颗粒聚集体(24)储存。
