Standard export sawdust pellets

Currently, the production of sawdust pellets for export is no longer strange to Vietnamese manufacturers. For each different customer, the requirements for pellet specifications are also quite different.

Currently, the production of sawdust pellets for export is no longer strange to Vietnamese manufacturers. For each different customer, the requirements for pellet specifications are also quite different. But there is a certain common point that the energy generated must be from 4500 - 4800 Kcal / kg and the amount of dry ash must be small, less than 1%, this is a quite popular product in the markets of Korea, Japan, USA, Canada, Europe,..

Energy from sawdust pellets must reach 4500 – 4800 Kcal/kg

To achieve the above specification, the production process usually requires:
Firstly, to produce the required amount of dry ash, the pellets must have a small size that can be 5mm or smaller. Thus, the materials from sawdust must be quite small in size. But when purchasing from wood production facilities, the size of sawdust is not always desirable, especially in the case of buying from many suppliers. Therefore, in order to ensure the requirements, the pellet production facilities must grind all materials through a wood crusher, not as small as possible. But they must be both small and synchronous to make the tablets of satisfactory size.
In the tablet production process, the thing that greatly affects the quality of the finished product is the moisture content of the tablets. Normally, in order for the product to be of suitable quality for export, the pellets must have a moisture content of 13 - 14%, but the moisture content of the raw materials after grinding often fluctuates between 18 -35 %, so it is necessary is to lower the humidity. According to the original production method, it will be sun-dried, so only experienced people know how long it takes to dry and the weather is not always stable. So in the industrial process, people will proceed to dry with the right humidity level.

Finished sawdust pellets
After we have prepared the materials, we put them into the pellet machine with the previous production process, the process can be done manually, but now we do it through a conveyor system, screw conveyor. to ensure that the tablets are uniform in size and more beautiful. When the compression is complete, the temperature of the tablets is quite high, so it is necessary to proceed to the cooling system, if there is no system, we let it cool and then proceed to pack the product.
It can be seen that the process of producing sawdust pellets meeting export standards is not too difficult, but it only requires the producer to pay attention in a few stages to ensure the right quality as required.e name on documents such Natural pebble stone size 2mm-10mm
