Solid barbecue charcoal and preparation method thereof

Abstract

The invention relates to a fuel for burning. A solid charcoal for burning is made of bamboo sawdust, wood sawdust, or the mixture of both bamboo sawdust and wood sawdust. The sources of raw materials in the invention are wide and comprises waste of the wood sawdust and the bamboo sawdust, etc., reclaimed from the factories. The waste is effectively processed into solid core barbecue, the shape of which is the same as that of pure bamboo or solid charcoal. Since the components are pure, the charcoal has no smoke when being burned. The burning time of the charcoal is equal to that of the pure bamboo or solid charcoal. Compared with the composite charcoal, the similar products can extend the burning time for 1-1.5 hours, with small size and low cost. The components are made of natural fuels, without others. The product is with high quantity of heat, little ash and is not easy to be broken off when burning and poking the charcoal. The practicality is high. The invention has a simple technology and can control the performance of the product most effectively. The product can be comparable with the pure natural raw carbon.

Description

Technical field:

[0001] The present invention relates to fuels, especially barbecue fuels. Background technique:

[0002] Barbecue is a delicious food loved by people from all over the world. When making it, the quality of its fuel barbecue charcoal varies greatly. The best is pure solid wood or pure bamboo charcoal. However, at present, forest resources are scarce, not only the source of materials is limited, but also its processing The process also causes waste and high cost. At present, it is gradually being replaced by bamboo charcoal or machine-made charcoal with a shorter growth period. Machine-made charcoal is mostly made of sawdust pressed into sticks and then fired into porous machine-made charcoal. This kind of charcoal is low in cost, but large in size and short in burning time. Chinese patent application 200610052446.4 discloses a machine-made charcoal, which is a solid machine-made charcoal made of bamboo charcoal powder, cornstarch and water. However, the soli...

Examples

Embodiment 1

[0017] according to figure 1 The shown process flow produces 100% pure bamboo sawdust solid body barbecue charcoal, and the specific method is:

[0018] The first step, raw material preparation: Recycle the waste bamboo sawdust from various factories, crush and sieve to obtain particles, then transfer the raw material particles to the drying drum or heating furnace for drying, and then enter the cyclone separator for centrifugal drying to Moisture content is 3%;

[0019] The second step, rod making: transport the above-mentioned prepared raw material particles to the screw extruder, extrude the rod under pressure to make a square cross-section salary rod, and automatically cut the salary rod according to the length requirement;

[0020] The third step, carbonization: the cut-off fire rods are transported to the charcoal kiln for carbonization. The carbonization is staged high-temperature carbonization. The initial carbonization is 550°C for 2.5 hours, and then the temperature...

Embodiment 2

[0022] according to figure 1 The process flow shown produces 100% pure wood sawdust solid barbecue charcoal, and the specific method is:

[0023] The first step, raw material preparation: recycle waste wood sawdust from various factories, crush and sieve to obtain particles, then transfer the raw material particles to a drying drum or a heating furnace for drying, and then enter a cyclone separator for centrifugal drying to Moisture content is 5%;

[0024] The second step, rod making: transport the above-mentioned prepared raw material particles to the screw extruder, extrude the rod under pressure to make a circular cross-section salary rod, and automatically cut the salary rod according to the length requirement;

[0025] The third step, carbonization: the cut fire rods are transported to the charcoal kiln for carbonization. The carbonization is high-temperature carbonization in stages. The initial carbonization is at 600°C for 2 hours, and then the carbonization is carried...

Embodiment 3

[0027] according to figure 1 The shown process produces bamboo and wood mixed solid body barbecue charcoal,

[0028] The first step: prepare bamboo sawdust and wood sawdust according to the raw material preparation method described in Examples 1 and 2;

[0029] The second step, rod making: the above-mentioned prepared bamboo sawdust and wood sawdust are mixed in a weight ratio of 2:1, and the mixed raw material particles are transported to a screw extruder, and extruded under a 15 kilowatt motor to make rods. Make a hexagonal cross-section salary rod, and automatically cut off the salary rod according to the length requirement;

[0030] The third step, carbonization: the cut-off fire rods are transported to the charcoal kiln for carbonization. The carbonization is high-temperature carbonization in stages. The initial carbonization is 600 ° C for 2 hours, and then the temperature is raised to 1000 ° C for 4.5 hours until it is completely carbonized and then it is out of the ki...
