AI Technical Summary
In the existing technology, during the production of block dry ice, the uneven size of the dry ice particles leads to incomplete compression, which can easily cause problems such as air pockets and affect the formation of high-density block dry ice.
A dry ice production feeding structure was designed. By rotating the rotating plate, the positions of the first and second feeding holes are adjusted to screen out large and small dry ice particles. The particles are kept stable by using an insulation sleeve. After absorbing heat, they sublimate to form particles of a suitable size for compression.
This technology enables uniform screening and temperature control of dry ice particles, ensuring uniform volume of dry ice particles during compression, preventing air pockets, and improving the density and quality of block dry ice.

Description
TECHNICAL FIELD

[0003] The block dry ice is compressed to form high-density block dry ice during production, and the particle size of the granular dry ice needs to be paid attention to during compression. Larger dry ice particles need more pressure to be compressed, and when compressed with small particle dry ice, it is easy to appear that the large particle dry ice is not completely compressed, resulting in problems such as hollow inside the block dry ice, which is not conducive to forming high-density block dry ice.

The dry ice particles of large volume are left on the rotating plate, and the dry ice particles of small volume fall below and can be compressed.
