Differences between "Direct Pressing," "Dry Ice Pellets," and "Recycled Dry Ice Re-Pressing"

Direct Pressing of Dry Ice: This is a process for manufacturing dry ice pellets (blocks) where a compressor is used to inject liquid carbon dioxide (CO2) into a molding die. The CO2 is then cooled and pressurized to form uniform and regular dry ice pellets (blocks). This process is typically employed for producing high-quality dry ice suitable for various applications, such as food transportation, refrigeration, and special effects. Specialized equipment is often required for different sizes and shapes of dry ice.

Dry Ice Pellets (Dry Ice Particles): Dry ice pellets are generated during the manufacturing of dry ice. These are small particles of solid carbon dioxide, often used for refrigeration and special effects. These particles are usually produced directly through the manufacturing process and may not be perfectly regular in shape, but they are still applicable for various purposes.

Recycled Dry Ice Re-Pressing: This process involves reprocessing used or discarded dry ice fragments to form solid dry ice blocks. It includes repressing waste dry ice shards to create homogeneous blocks. While the primary aim is cost-saving through the reuse of dry ice, this method can lead to irregular shapes and inconsistent quality.

In summary, the dry ice utilized by Trading Excellence undergoes the "Direct Pressing" method, known for its advantages such as slow sublimation, consistent volume with lower weight, and ease of cutting, ensuring customers receive high-quality dry ice.
