Làm thế nào để sản xuất than shisha chất lượng cao?

In the world of hookah enthusiasts, the quality of charcoal determines everything. A piece of charcoal that burns for an extended period, emits no smoke or odor, and leaves only a layer of snow-white ash after combustion is regarded as a top-tier treasure. It can bring an exceptional reputation and higher prices to a brand.

So what secrets lie hidden in the transformation from ordinary coconut shells or bamboo powder into a high-quality hookah charcoal block?

The answer lies in meticulous control over every production detail. Today, we reveal the three core technological factors that determine hookah charcoal quality and show you how to master them using professional equipment.

Selection and proportion of adhesives

Hookah charcoal powder requires a binder to be compressed into shape. This is the most error-prone step and the one that most clearly distinguishes between high-quality and inferior products.

• Poor choice: using chemical binders or low-grade starch. This produces unpleasant odors and harmful smoke during combustion, directly causing headaches and nausea for users while completely ruining the hookah’s fruity flavor.
• Good choice: must use food-grade, pure natural plant starches like cornstarch or tapioca starch. These burn colorless and odorless, preserving the hookah’s natural aroma.
• Golden ratio: binder proportion is critical.
  • Too little: loose charcoal structure breaks easily during transport and fractures during combustion.
  • Too much: charcoal blocks become excessively hard, difficult to ignite, and produce more ash during combustion.
  • Mastering the process: a high-performance mixer is essential. It must blend precisely measured adhesive and water with charcoal powder to achieve an extremely uniform mixture, ensuring every particle of charcoal powder is coated with the appropriate amount of adhesive. Only this guarantees consistent performance across the entire batch.

Pressure of the tablet press

The density of charcoal briquettes directly determines their burn time and hardness. Density, in turn, is entirely dependent on the pressure the tablet press can deliver.

• Insufficient pressure: produces low-density briquettes with numerous internal voids. This leads to:
  1. Rapid combustion: increased oxygen exposure accelerates consumption, requiring frequent briquette replacement.
  2. Fragility: high breakage rates during packaging and transportation.
  3. High ash content: incomplete combustion produces more ash residue.
• Ideal pressure: a powerful hydraulic press machine delivers stable, immense pressure. Under high pressure, charcoal powder is tightly compressed into high-density briquettes. Benefits:
  1. +30%+ longer burn time: more fuel packed into the same volume.
  2. Durable and robust: products resist fragmentation and produce a crisp sound upon impact.
  3. Reduced ash content and whiter appearance: indicates more complete and purer combustion.

The Art of Drying Processes

Freshly pressed charcoal briquettes contain approximately 30-35% moisture and must undergo drying to become the final product.

Incorrect drying: rapid heating and rushing the process. This causes excessive temperature differences between the interior and exterior of the briquettes.

Internal moisture rapidly vaporizes and expands, shattering the partially dried outer shell and creating numerous cracks. Cracked briquettes are considered defective.

Proper drying: a phased, gradual drying process is essential.

• Low-temperature preheating stage (approx. 6-8 hours): use lower temperatures to slowly evaporate surface moisture, forming a slightly hardened outer shell.
• Medium-temperature heating stage (approx. 10-12 hours): gradually increase the temperature, allowing heat to penetrate the interior and slowly force out core moisture.
• High-temperature setting phase (approx. 4-6 hours): finally, use high temperatures to completely remove residual moisture, fully drying and setting the charcoal blocks.
  • How to achieve: a professional drying room is essential. It must be equipped with a programmable temperature control system and forced hot-air circulation fans to ensure uniform temperature throughout the chamber. Strict adherence to the preset temperature curve guarantees a yield rate exceeding 99%.
