Is it necessary to install pellet cooler?

The sawdust pellets produced by sawdust pellet making machine can not be packaged or stored directly because of the high temperature and high moisture content after extruding. It needs manual drying or equipped with the pellet cooler. Proper pellet cooler can improve the working efficiency of the sawdust pellet making machine, reduce the processing cost and effectively reduce the waste of labor and pellets, and ensure the continuity production of sawdust pellets.


 
The purpose of equipping pellet cooler for sawdust pellet making machine is to reduce the waste of manual work and the rate of pellet damage and realize continuous operation. Moreover, closed cooling and drying can effectively control the processing cost of sawdust pellets. However, due to the capital difficulties and limited space, some enterprises are confused about the allocation of pellet cooler.
 
Generally speaking, for the sawdust pellet making machine with daily production of 2-3 tons per day and 1-3 hours production time, sawdust pellets produced can be manually dried. Once it is larger than the production time and output, it is necessary to use and configure the pellet cooler. About 30,000 to 40,000 yuan will be paid for two drying labors each year, and it also takes about 40,000 yuan for a small output pellet cooler. However, annual payment is needed for labor input, while the pellet cooler can be used for 4-12 years. The pellet damage rate of manual air drying is about 3-7%, while that of the cooler is about 1-4%. In addition, the work effect of air drying in rainy season is poor, because the air humidity is higher, which needs longer drying time, and the pellets would get damp easily.
