The Standard of wood pellets for export
Update: 11/15/2017At present, the production of sawdust pellets for export is no longer unfamiliar to Vietnamese producers. For each customer, the requirements for tablet formulations are quite different. But there is a common point that the energy generated must be 4500 - 4800 Kcal / kg and dry ash must be small, less than 1%, this is quite popular products in the markets of Korea, Japan, America, Canada, Europe
To achieve the above specifications, the production process usually requires:
First, to achieve the required amount of dry ash, the pellets should have a small size of 5mm or smaller. This requires that the material from the saw is relatively small in size. But when buying from wood production facilities, the size of the saw is not always desired, especially in the case of buying from many suppliers. Therefore, to ensure the requirement, the pellet production facilities must crush all the ingredients through the wood crusher, not as small as possible. They have to be both small and have the new synchronicity to make the tablets have the required size.

In the process of producing tablets, the major influence on the finished product quality is the moisture content of the tablet. Normally, in order for the product to be of good quality for export, the tablet must have a moisture content of 13-14% but the humidity of the material after milling usually fluctuates between 18 and 35%. It is to lower the humidity. In the original aquascaping, the sun will be exposed, so only experienced people know how long it is exposed and the weather is not always stable. So in the industrial process people will be drying with the moisture level in accordance with the standard
nce the raw materials have been prepared, they are fed to the pelletizer with the previous production process. The process of filling can be done by hand, but nowadays we use the conveyor system, the loading screw to ensure the tablet size is more uniform and beautiful. When the compression is finished, the temperature of the tablet is quite high, so it should be put into the cooling system, if there is no system, then let cool and then pack the product.
It can be seen that the production process of sawdust pellets meeting the export standards is not too difficult, but it requires only the producers to note in a few steps to ensure the required quality.
