Popular Science Of Hookah Charcoal

The hookah charcoal, as its name implies, is the charcoal used to smoke hookah. This hookah is different from the filter tip cigarettes we usually see. It is somewhat similar to the hookah smoked by rural elders in the past. However, the hookah in China directly ignites the cut tobacco, while the hookah in foreign countries uses a heat source to heat the cut tobacco to produce smoke, and then smokes through a set of hookah bottles. The heat source mentioned here is hookah charcoal. Now, although there is an electronic hookah can be heated by electricity, the friends who often smoke hookah do not like it. They think that the most authentic hookah should be heated by charcoal, just like we eat barbecue and think that the electric barbecue is not as good as the charcoal barbecue. In recent years, hookah has become very popular in the Middle East, Europe and the United States. Now it has spread to Hong Kong and Taiwan. Pumpkin has become a very fashionable pastime. It is expected that it will also become popular in China in the future. Accordingly, as a consumable, the amount of hookah charcoal is also large. Most importantly, its price is very expensive compared with other charcoal, belonging to the nobility of charcoal.
The question is, why did the hookah charcoal become the aristocrat of charcoal?
When pumping smoke, first wrap the cut tobacco and spices with tin foil, and then use toothpicks to prick a few eyes on the tin foil. Then put the ignited hookah charcoal on the cut tobacco, and heat the cut tobacco to produce smoke. This puts forward high requirements for the charcoal that ignites the cut tobacco. It must be hard, non divergent, high-density, easy to ignite, burning time and even heating.
hardness
The hookah charcoal must be hard enough, or it will disintegrate if the heating intensity is not enough during combustion. That is to say, the charcoal must be blocky and not broken during the combustion of hookah charcoal. There are several simple test methods for testing the mechanical strength of hookah charcoal:
1. Throw the hookah charcoal on the cement floor without breaking;
2. Use two hookah chars to collide with each other, without fragmentation or slag falling;
3. If it is easily crushed or broken into powder by hand, it is not a good hookah charcoal.
density
The density of good hookah carbons is relatively high. Generally speaking, the proportion of good hookah carbons exceeds 1.3. We can also detect it through small experiments:
Fill a cup with clean water, and then put the hookah charcoal in. If the hookah charcoal sinks into the water bottom, it means that its specific gravity is greater than 1, and it is qualified; In addition, the hookah charcoal can be kept intact for a long time after entering the water, indicating good quality. On the contrary, if it dissolves into carbon slurry in a short time after entering the water, indicating poor quality.
Ignition time
The hookah charcoal is different from the barbecue charcoal. It is required to be lit quickly, otherwise the customer will smoke and the charcoal will not be lit. This is the most ridiculous.
Burning time
One of the most important indicators of hookah charcoal is the burning time. If the burning time is too short, the charcoal will be replaced during smoking, which will have an impact on the taste of hookah. Therefore, customers will make requirements on the burning time of hookah charcoal. For example, hookah charcoal with cube dimensions of 25 * 25 * 25 should be able to burn for at least 90 minutes.
Combustion characteristics of soot
Good hookah charcoal requires high calorific value and combustion time, and must have the following combustion characteristics:
Temperature and flame stability: 40-50 minutes
Hardness: charcoal is not easy to break when burning
Surface temperature: about 320 ℃
No odor
smokeless
No surface toner
Red flame
Constant flavor when burning
Ash characteristics
Generally, customers who smoke hookah hope that the charcoal ash is white, but in fact, the color of charcoal ash is directly related to the raw materials. However, no matter what the color of ash is after combustion, it has little effect on the quality of hookah charcoal, just the perception is different.
However, the ash content is also one of the indicators to measure the quality of hookah charcoal. The ash content of hookah charcoal with good quality is required to be no more than 6%,
