Новое поколение многофункциональной машины для производства барбекю небольшая автоматическая машина приготовления

With increasing pressure on the earth's resources, turning different types of organic waste into clean-burning fuel helps save forests and cuts greenhouse gas emissions by replacing wood, charcoal and fossil fuels for cooking and industrial processes. Aside from being cleaner and easier to handle, biomass briquettes made by Wanqi sawdust screw extruder are also less polluting.

• Key facts related to charcoal rod briquetting machine

1. Many waste materials, from sawdust to rice husks, can be turned into clean-burning, easy-to-handle fuels that cut waste and carbon emissions through Wanqi sawdust screw extruder.

2. High pressure briquetting plant can produce over 50 tons of briquettes per day.

3. About five million tons of biomass pellets used in Europe in 2010.

4. Briquettes and pellets sell for about US $80 and US $300 per ton.

• General introduction of charcoal rod briquetting machine

charcoal rod briquetting machine is used for pressing charcoal powder, which could be carbonized sawdust from corn stalk, corn cob, branches, leaves and other agricultural materials, to briquettes, which are high-volatile fuels, and are widely used in chemical, medical industries, environmental protection and other industrial fields. Charcoal briquettes are also popular in barbecue, hot pot, household heating and other civilian areas. 

• Main features of charcoal rod briquetting machine

1. Simple operation and easy to change consumables


2. Efficient and energy saving


3. Re-compacting the unqualified final products easily

• Raw materials for charcoal rod briquetting machine

The raw materials for charcoal rod briquetting machine could be the following: weed tree, straw, rice straw, rice bran powder, peanut shells, pine wood residues, floor powder, bamboo powder, hemp fiber, waste paper, reed canary grass, sunflower husk, seed shell, switch grass, sawdust, wood, wood branches, leaves, coconut shell, peanut shell, rice husk, corn stalk, grain stems and other agriculture wastes.

The feeding size of raw materials for charcoal making machine should be less than 5mm. If the raw materials are bigger in size, they must be crushed firstly.

The feeding moisture of raw materials must be less than 12%, otherwise the outlet briquettes are easy to be broken, and have crevice. So before briquetting, the over wet materials should be dried before putting them into sawdust screw extruder.

• End Products for charcoal rod briquetting machine

The end products from charcoal rod briquetting machine can be round, rectangular, hexagonal stick and other customized shape. And they can be 50-80mm in diameter, and 15-80cm in length. The end products from sawdust screw extruder have the features of high density, easy to restore, small in size, etc.

• Technical parameters of charcoal rod briquetting machine

• Working principles and the classification of charcoal rod briquetting machine

There are two approaches to briquetting, both of which require the loose biomass to be ground into a coarse powder like sawdust.

High pressure briquetting

High pressure briquetting uses a power-driven press to raise the pressure of dry, powdered biomass to about 1,500 bar (150 MPa). This compression heats the biomass to a temperature of about 120°C, which melts the lignin in the woody material. The press forces the hot material through a die at a controlled rate. As the pressure decreases, the lignin cools and re-solidifies, binding the biomass powder into uniform, solid briquettes.

The three main types of high-pressure briquetting machine are as following.

1. The piston press, which uses an oscillating piston to compress the biomass, and produces cylindrical briquettes, 50 to 100 mm in diameter.

2. The screw press, which uses a tapered screw, and produces longer, hollow briquettes. Wanqi sawdust screw extruder is the one of this type.

3. The pellet mill, which compresses the biomass between rollers and makes smaller cylindrical pellets (similar to animal feed pellets) 6 to 12 mm in diameter.

The dies and moving components in the machines need to be made from hardened steel, because they are worn down by the biomass at the high pressures used. Even so, they need to be replaced quite often. Lower pressures can be used if the die is heated, but this requires additional energy. The good news is that, as a professional manufacturer of briquetting machine, Wanqi supplies all the spare parts for our sawdust screw extruder.

Wanqi sawdust screw extruder is produced in a wide range of sizes. Wanqi provides a range capable of processing 130 kg/hour to 500 kg/hour. The powder required to run a sawdust screw extruder is only about 5% of the heat produced by the briquettes, which is range from 11 to 22 Kw.

Low pressure briquetting

Low pressure briquetting can be used for materials with a low amount of lignin, such as paper, and can also make use of charred residues and charcoal dust. Low-pressure briquetting machines can be electrically powered, but are often hand operated, using a lever that drives a piston to compress the paste.

• Benefits of charcoal rod briquetting machine

charcoal rod briquetting machine makes use of biomass residues that would otherwise go to waste, this can bring a useful income stream to the farms and sawmills that produce residues.  By replacing the use of wood and charcoal (often produced unsustainably) and fossil fuels, briquettes cut greenhouse gas emissions and deforestation.

Briquettes made by Wanqi sawdust screw extruder are easier to store and use for cooking than wood or charcoal, because they are uniform in size and composition. They are cleaner to handle than charcoal or coal, and produce less local air pollution.

There are some concerns about using field waste for briquettes, because they are also valuable as a soil improver. However, residues like sawdust and rice husk have limited agricultural use and can be a fire hazard, as can pine needles.

In many countries there are significant resources of biomass residues, which are not needed for agriculture. Thus as the cost of conventional fuels increases, the use of biomass briquettes and pellets is likely to grow with the assistant of Wanqi sawdust screw extruder.
