Small pellet mill, or homemade pellet mill is a very popular topic nowadays. However, first of all you should know that the process of drying material is the most important stage of wood pellet production. The relatively high price of pellets for the moment due to these many costs in their manufacture. A significant proportion of their value is based on the costs associated with the drying process. According to research, these costs can be reduced significantly by using wood waste from sawmills, unsuitable for the production of pellets, such as bark and other wood waste in the processes of heat and electricity. Leaves also can be used as a main material for pellet mill production.

One of the factors determining the quality of pellets, is to provide input to appropriate moisture content. Since in most cases the raw material is significantly greater than allowable moisture is necessary even its pre-drying. The presence of excessive moisture in the feedstock may be a cause of various problems in the production process for developing high temperatures. For example, the feedstock with humidity over 15% of the extrusion process difficult, as difficult to press, especially the use of presses with round matrices. The result is thus poorly granular final product. The content of excess moisture in the wood determines obtain granules with a higher humidity than recommended, which makes them unsuitable for use as fuel pellet boilers.

The recommended humidity of the raw material before delivery to the press is between 8 and 12%. For optimal humidity is taken about 10% + / – 1%. Providing material with similar moisture content suggests that a final product quality.During the production of pellets for drying the raw material used mainly two types of dryers – drum and belt. The choice is determined depending upon the feedstock (wood chips, sawdust), the quality requirements of production and the available heat source.
