The charcoal of kebabs is generally what kind of wood burns charcoal, is not as long as it is

Machine-made charcoal, also known as artificial charcoal, recycled charcoal, and smokeless clean charcoal, is a carbonaceous rod made of extrusion from wood scraps. The raw materials of cob charcoal are extensive, such as rice husks, peanut husks, cotton husks, corn cobs, corn stalks, sorghum stalks, etc., which can be used as raw materials to produce cob charcoal, with sawdust, shavings, and bamboo chips as the best. It has high density, high calorific value, smokeless, tasteless, pollution-free, non-polluting, non-combustible, and is internationally recognized as a green and environmentally friendly product.

Mechanism charcoal features:

1. Environmental protection: do not cut down trees, use bamboo and wood products waste production, and turn waste into treasure. The production of ordinary charcoal requires cutting down trees and destroying the ecological environment.

2. High energy: the fixed carbon content is about 80%, and the calorific value is 7500-8000kcal kg, while the fixed carbon content of charcoal is low, and the calorific value is about 6500kcal kg.

3. Cleanliness and hygiene: smokeless, no charcoal, no sparks in combustion, the residual ash will fall naturally during combustion and will not float up, and the ash content will be less and flammable after burning about 3% or 6%.

4. Regular shape, reasonable structure, easy to use: there is a uniform length and size, hollow or solid structure, which is conducive to combustion and use.

5. Low water content, within 5%: Ordinary charcoal has a large water content.

6. The product does not contain chemical substances, is non-toxic, has no peculiar smell, is non-polluting, and has the advantages of long combustion time.

Disadvantages: not easy to ignite, slightly higher.

It is recommended that friends who do barbecue buy mechanism carbon will be much better, not to mention the long burning time, the most important thing is that the carbon itself has no smoke. The reason why barbecue is accused by many people of being too dirty actually has a lot to do with the carbon we usually use. If we can improve this, I believe that the barbecue will still be eaten by many people.

Li Mu. However, if you don't have one, you can replace it with another fruit tree.

Pour in a little alcohol and other accelerants to allow the charcoal to fully absorb and start a fire.

After 10-15 minutes of burning, the open flame gradually decreases or disappears, and white ash appears on the surface of the charcoal, which indicates that the ideal grilling temperature has been reached, and the charcoal can be spread evenly and you can start to grill and eat.

Since the special flavor of charcoal-grilled food comes from the aroma of grilled food when charcoal is hot, choosing good charcoal is the basis for enjoying deliciousness. Therefore, the choice of charcoal fire is the first important thing. When choosing charcoal, you must not try to be cheap, some inferior charcoal is not enough fire, or even does not burn at all, and some will produce a lot of smoke to pollute the food after burning.

The charcoal is generally neater and heavier, so the charcoal burns for a long time and the fire is very good.

There are several types of charcoal, and what kind of charcoal is used for barbecue.

At present, there are three main types of charcoal used for barbecue on the market: flammable carbon, ordinary charcoal, and machine-made carbon. 1. The most advanced mechanism carbon on the market is the traditional charcoal and coal processing synthesis, this carbon has the advantages of long burning time, uniform firepower, smokeless, etc., used for barbecue can make the food evenly heated, not easy to appear baked paste or half-cooked love bush branches; Moreover, the smoke-free nature is also conducive to maintaining the original flavor of the ingredients; More importantly, mechanism carbon also has the advantages of environmental protection, high energy and low energy.

2. Ordinary charcoal is the way used in traditional barbecue, but the disadvantages of ordinary charcoal are more obvious, the burning power is uneven, it is easy to roast the food, the burning time is short, and the smoke is burned. 3. Although flammable carbon is also a very practical barbecue carbon, the advantages are also obvious, but the disadvantage alone is that it is more expensive and not suitable for mass consumption.

There are several reasons why charcoal is used for barbecue:

1.High combustion temperature: The calorific value of charcoal is high, and the combustion temperature can reach more than 1000, which can quickly heat up, making the barbecue more rapid and uniform.

2.Long burning time: Charcoal burns for a relatively long time, which can provide a long-lasting heat source for the roast, ensuring the doneness and taste of the roast.

3.The smoke from burning tastes good: When charcoal is burned, it produces a smoky flavor that adds a unique aroma and texture to the roast.

4.Easy to carry and store: Compared with electrical equipment such as gas and electric grills, charcoal is lighter, easy to carry and store, suitable for outdoor activities and picnics.

Therefore, charcoal is one of the commonly used fuels for barbecue, and its high temperature, long burning time, and smoky taste are its advantages.

Reasons for using charcoal for barbecue:

Charcoal is fired, generally pine Qi Xi stool after firing and processing charcoal is the best, there is no smell of smoke, and at the same time, the food roasted by Lu Zhao has a unique smoke fragrance of pine.

In addition, charcoal is easy to ignite, the burning temperature is high, and the brigade is not too high, so it is not easy to burn the food.

The charcoal used for barbecue is made of clay to build a kiln, filled with wood, and burned from the kiln door or fire door to make the wood charred in the kiln, and the volatiles escape and the charcoal remains.

According to the raw materials used for charcoal burning, it can be divided into:

Hard broad charcoal. It is mainly composed of hard broad-leaved woods such as Quercus and Quercus spp., and the secondary ones are Birch. Such as water green gang, birch, hemp oak, bitter oak, elm, maple and so on.

Broadleaf charcoal. Charcoal made from a mixture of hard and soft hardwood. Such as poplar, linden, willow and so on.

Pine charcoal. Charcoal fired from pine or other coniferous wood. Such as masson pine, Korean pine, spruce, etc.

All high-quality or qualified firewood is suitable for sitting on charcoal.

Pine trees are not good, because they are extremely non-flammable, and they are smoking, and pine trees cannot be used as firewood, which will clog the kang holes.

Linden trees and poplars are not good, because the texture is loose, so it will drop the slag, and the slag is the powder is flying and smoking, and it is not resistant to burning, most of the other numbers in Jilin Province are suitable for making charcoal, if it is a mechanism charcoal, it is simple, bud rice sticks, rice bran, straw, sawdust, all kinds of garbage can be.

Charcoal, wood piled into a sealed kiln, let him simmer in isolation from oxygen.

It used to be wood, but now there is bamboo charcoal on the market, and the composition is bamboo.

Wood is burned with fire, and after it has been burned, it is charcoal.

Analysis: Activated charcoal.

activated carbon

Activated black porous solid carbonaceous. It is generally powdered, granular or pellet-like, and the main component is carbon, and it also contains a small amount of oxygen, hydrogen, sulfur, nitrogen, and chlorine. In the early days, the raw materials for the production of activated carbon were wood, hard fruit husks or animal bones, and later coal was mainly used, and the production methods were:

Steam and gas activation method. Carbon is activated at 850 900 using water vapor or carbon dioxide. Chemical activation.

Activated carbon can be obtained by using the gas released by the activator or by impregnating the raw materials with the activator, and after high temperature treatment.

Activated carbon has a microcrystalline structure, the arrangement of microcrystals is completely irregular, and there are micropores (radius less than 20 angstroms 10-10 meters), transition pores (radius 20 1000), macropores (radius 1000 100000), so that it has a large internal surface, with a specific surface area of 500 1700 meters 2 grams. This determines that activated carbon has good adsorption, which can adsorb metal ions, harmful gases, organic pollutants, pigments, etc. in wastewater and exhaust gas. The industrial application of activated carbon also requires high mechanical strength, good wear resistance, stable structure, and low energy required for adsorption, so as to facilitate regeneration.

Activated carbon is used for decolorization, deodorization, gas separation, solvent** and air conditioning of oils and fats, rolling beverages, food, drinking water, and is used as an adsorbent for catalyst carriers and gas masks.

The charcoal used to roast lamb, which is made from the dry distillation of trees, is a fuel. The general method of burning charcoal is to stack wood in the kiln, and after ignition, when the charcoal kiln reaches a certain temperature, close the air inlet of the charcoal kiln, and let the waste heat dry the wood, and then get charcoal. Zhang Side, who served the people of the Great People's Congress, died when the charcoal kiln collapsed when he burned charcoal.

Charcoal should be divided into two kinds, one is the log charcoal made directly from broken wood or logs, and the other is the machine-made charcoal made by using a charcoal machine.

The old-fashioned process is to burn charcoal, that is, the trees are cut into sections, ignited in the charcoal kiln, burned to a certain extent, the charcoal kiln air is closed, the waste heat continues to heat the wood for dry distillation, the water and wood tar are boiled out, and the wood is carbonized into charcoal. This is similar to the past when families burned firewood and held charcoal.

At present, there is a method of processing charcoal using wood chips and other waste materials, pressing these waste materials into shape, heating them indirectly in a furnace for dry distillation, and carbonizing these raw materials into charcoal.

Barbecue charcoal introduction

First of all, you have to dig a charcoal kiln. The kiln is filled with half-dried whole firewood. Then seal the kiln, and then burn the small kiln into the kiln with a large fire from the fire hole dug when digging the kiln for a day or two. The principle is to carbonize firewood at high temperature in an oxygen-deficient environment.

The principle is the same, it is all oxygen-free carbonization in the kiln, but there is not much left of the earthen kiln with the ban in recent years, so the charcoal burners will lock their eyes on the carbonization furnace. Airflow carbonization furnace and dry distillation carbonization furnace are two different equipment. The dry distillation carbonization furnace can be more effective in the flue gas and meet the requirements of environmental protection.

Any charcoal can be used for barbecue, and the common charcoal on the market is flammable charcoal, charcoal, and machine-made charcoal. Flammable charcoal is available in outdoor stores and is available in square and pie shapes. There is a flammable layer on the surface of flammable charcoal, which is easier to ignite than ordinary charcoal, and the disadvantage is that it is more expensive.

The price of ordinary charcoal four kilograms is only 20 yuan, but the size of the inside is different, it is easy to have uneven fire power when grilling, and the burning time is short, and the charcoal must be continuously added during the roasting process. Machine-made carbon is actually made by mixing carbon and coal, and is pressed into a hollow polygonal shape, which can be seen from the carbon ash containing coal.

This kind of charcoal has a uniform size, a long burning time, uniform firepower, smokeless, and inexpensive, many professional barbecue restaurants choose this kind of charcoal, but the process of ignition is more laborious.
