Document Type and Number:
WIPO Patent Application WO/2016/084508
Kind Code:
A1
Abstract:
[Problem] To provide a dry ice freezer and crusher from which homogenized pulverized samples can be obtained more efficiently.
[Solution] A dry ice freezer and crusher formed from: a crushing container (1) which is provided with a container main body (3) constituted of a bottom plate (5) and a side plate (6) standing up from the peripheral edge of the bottom plate (5), having an upper surface opening (B), and provided internally with a pulverizing blade (C) and is provided with a cover body (4) which closes off the upper surface opening (B) and in which a gas release hole (7) is formed; and a crusher main body (2) which is provided with a drive device (D) for rotating the pulverizing blade (C). The side plate (6) of the container main body (3) is formed by a vacuum double-wall structure by vacuum evacuating an internal space (S1) formed by metal plates (P1A, P1B) that face each other. A radiant heat transfer prevention body (Q1) is provided that serves as a mirror in the internal space (S1). The insulating properties of the container main body (3) are extremely high; therefore, the inside surface temperature for the side plate (6) is not increased by the effects of ambient temperature when crushing a sample at room temperature, so no part of the sample adheres to the inside surface of the side plate (6) during crushing.
