Bamboo Pellet Mill Plant In Thailand

RICHI MACHINERY

overview

In order to meet market demand, the project client, a bamboo products company, invested 220,000 US dollars to build a new project with an annual output of 3,000 tons of machine-made charcoal and 7,000 tons of bamboo pellets. It comprehensively utilizes local bamboo processing waste to produce bamboo charcoal, turning waste into treasure, opening up a new way for bamboo processing waste treatment, and achieving economic and environmental benefits.

Thailand has a warm and humid climate, which is suitable for bamboo growth. It has a large number of bamboo forests, which provide sufficient raw materials for processing. Bamboo chips can generally be used for fuel, papermaking, processing bamboo fiber, bamboo charcoal, etc. Among them, papermaking and processing bamboo fiber have higher costs and relatively more pollution; while processing bamboo charcoal has lower costs and relatively less pollution.

Bamboo charcoal is mainly used as activated carbon and barbecue fuel. It also has super strong adsorption capacity and releases negative ions. It has significant adsorption and decomposition effects on formaldehyde, benzene, ammonia and other major pollutants in indoor air and car air. The product has a wide range of applications and has good development prospects.

The total number of people in this bamboo pellet mill plant in Thailand project is 12, including 2 managers and 10 production workers, with an annual production day of 250 days. The crushing, drying and extrusion processes are produced for 8 hours a day, no production at night, and the carbonization process is produced continuously. The managers live in the factory, and the other 10 do not eat and stay in the factory.

Why is Thailand suitable for bamboo pellet processing business?

In addition to its own rich bamboo resources, the Thai government encourages the development of renewable energy and environmental protection industries.

As a green industry, bamboo pellet processing may receive policy benefits. With the increase in global demand for renewable energy, bamboo pellets, as a biomass energy, have broad market prospects and are in demand in both the local and international markets in Thailand.

Thailand’s labor costs are relatively low, and bamboo grows rapidly, and the cost of raw materials is also low, which is conducive to reducing production costs. Bamboo pellet processing helps reduce dependence on fossil fuels, reduce carbon emissions, and is in line with environmental protection trends. Thailand has a certain amount of technical accumulation in the fields of agriculture and biomass energy, and can provide technical support for bamboo pellet processing.

Processing technology design of Thai bamboo pellets

Description of bamboo pellet process flow:

1. Crushing: Place irregularly shaped and sized raw materials (bamboo chips, with a moisture content of about 50%) into a crusher and crush them into bamboo chips with uniform fineness of about 3mm.
2. Drying: Use a dryer to dry the crushed particles to a moisture content of between 6% and 12%.
3. Rod making: The crushed and dried raw materials are made into hollow strip semi-finished firewood sticks under the high temperature and high pressure of the rod making machine. The size of the firewood stick is: 2~6cm in diameter and 40~50cm in length.
4. Carbonization: Stack the semi-finished firewood sticks neatly in the carbonization pool, seal the air inlet, ignite, control the oxygen intake during combustion, and carbonize into charcoal. The carbonization process can generally be divided into three stages:
   • Drying stage: The project ignites the formed bamboo chips sticks. From the ignition to the furnace temperature rising to 160℃, the moisture contained in the machine-made sticks mainly evaporates by external heat and the heat generated by its own combustion. The chemical composition of the machine-made sticks has hardly changed.
   • Initial stage of carbonization: In this stage, the heat is mainly generated by the combustion of the sticks themselves, which raises the kiln temperature to between 160 and 280°C. At this time, the bamboo material undergoes thermal decomposition reaction, and its composition begins to change. Among them, unstable components, such as hemicellulose, decompose to produce CO2, CO and other substances.
   • Full carbonization stage: In this stage, the bamboo material undergoes rapid thermal decomposition, and a large amount of liquid products such as bamboo tar and bamboo vinegar are generated. In addition, combustible gases such as methane and ethylene are also generated. The combustible gas (gas product) actually generated during the carbonization and pyrolysis process of this project enters the pipeline for drying and combustion. During the pipeline transportation process, due to cooling, there will be condensed liquid products, namely bamboo vinegar and bamboo tar.
5. Pelletization: The dried wood chips are sent to the biomass bamboo pellet machine for extrusion molding.
