Description

  The present invention relates to a quantitative take-out apparatus for taking out a certain amount of granular dry ice.

  When frozen foods, ice confectionery, cakes, etc. are purchased at general retail stores, supermarkets, department stores, etc., they are usually handed with dry ice as a cold insulation material. Recently, granular dry ice such as cylindrical pellets has come to be used frequently because of the convenience that the required amount can be easily obtained and there are advantages in terms of safety and handling.

  In addition to such convenience, it has many advantages such as being able to store a considerable amount at once and hygienically, reducing loss due to sublimation, being economical and having sufficient weighing control. Therefore, this type of quantitative take-out apparatus that can take out granular dry ice with a simple operation and under accurate weighing tends to be used in relatively large-scale stores such as supermarkets and department stores.

As such a quantitative dry ice taking-out apparatus, for example, there is one shown in FIG. 7 according to the proposal of the present applicant (Patent Document 1).
This conventional granular dry ice dispensing device has a flat-bottomed pan-shaped housing (52) inside a granular dry ice storage chamber (51) formed in a heat insulating structure, and is rotatably accommodated in the housing (52). A rotary weighing device (55) having a disk-shaped housing (53) formed in a heat insulating structure and an upper surface plate (54) covering the upper surface of the housing (53) is disposed and disposed. A stirrer (57) provided with a plurality of rotating blade-shaped stirring blades (56) is disposed directly above the face plate (54), and the stirrer (57) and the casing (53) are synchronized. It is configured to be rotatable, and a granular dry ice introduction port having a partially arc-shaped cross section at a phase position different from the opening portion of the granular dry ice discharge passage (58) in a part near the periphery of the upper surface plate (54) ( 59), while the granular dry ice is positioned at a position corresponding to the granular dry ice discharge path (58) of the bottom plate of the housing (52) coaxially. A granular dry ice outlet (60) having an opening area smaller than that of the chair discharge path (58) is opened, and the granular dry ice inlet (59) and the granular dry ice are partly located near the periphery of the casing (53). A granular dry ice metering hole (61) having a size corresponding to the granular dry ice introduction port (59) is provided at a position corresponding to the ice outlet port (60) coaxially, and the granular dry ice storage chamber ( The granular dry ice take-out container (62) is arranged so as to be able to be taken in and out from the front side at a position corresponding to the granular dry ice discharge path (58) immediately below 51).

  The conventional granular dry ice taking-out apparatus shown in FIG. 7 allows the granular dry ice to be taken out as described below. The granular dry ice metering hole (61) formed in the rotary casing (53) matches the dry ice inlet (59) with the granular dry ice filled and accommodated in the granular dry ice storage chamber (51). At this time, the granular dry ice flows down to the granular dry ice metering hole (61) to store a certain amount of granular dry ice, and the granular dry ice measuring hole (61) is further rotated to rotate the granular dry ice measuring hole (61). ) And the dry ice outlet (60) coincide with each other, the granular dry ice is taken out by a fixed amount in a state where the granular dry ice is measured by the volume of the granular dry ice measuring hole (61).

In the case of this removal, since the stirring tool (57) that rotates in synchronization with the rotation of the housing (53) is disposed in the granular dry ice storage chamber (51), the stirring tool (57) Will rotate in the granular dry ice storage chamber (51), and therefore the stirring tool (57) that rotates even if the granular dry ice may cause a crosslinking phenomenon in the granular dry ice storage chamber (51). The bridge will be destroyed.
