Claims (1)
いて、原料を計量し可塑化スクリユに供給するに
際し、空気等のガス状物は通すが、パウダー等の
原料は通さない多孔質材を用い、同多孔質材部よ
り原料中に含まれた空気を脱気することを特徴と
する脱気式原料供給装置。 In plasticizing equipment for raw materials containing a large amount of fine powder, when measuring and feeding the raw materials to the plasticizing screw, a porous material is used that allows gaseous substances such as air to pass through, but does not allow raw materials such as powder to pass through. A degassing type raw material supply device characterized in that air contained in the raw material is degassed from a porous material part.
