We produced organic pellets of spent mushroom compost, but this pellets fermented.
Anyone know what may cause the fermentation of pellets? The compost is dried and then granulated, then packed.
Thanks Carlos, but the product before the pelletization, is subjected to a dryer, on tempertures of 250-300 ºC.
then the product is pelletized and packaged.
To have a fermentation, you should have humidity. Did you check the humidity of your pellets in the package?
To have a fermentation, you also need microorganisms.
If you have humidity, your intragranular temperature of your material was not so high than you believe. It is depending of the size of your particles. So some bacteria, sporulating bacteria or spores from mushroom can resist.
So, if your drying is not correct, you have humidity and microorganisms.
Which kind of dryer do you use?
