Pelletizing maʻamau o biomass laau pellet mīkini lako

1. ʻO ka ʻōpala i ʻoki ʻia: sawdust mai ka sawdust me kahi band saw. ʻO nā pellets i hanaʻia he mau hua paʻa, nā pellets maʻemaʻe, ka paʻakikī kiʻekiʻe a me ka hoʻohana haʻahaʻa.

2. ʻO nā mea liʻiliʻi liʻiliʻi i loko o ka hale hana hale: No ka mea he nui ka nui o ka ʻāpana, ʻaʻole maʻalahi ka mea e komo i ka wili lāʻau, no laila ua maʻalahi ke kāohi i ka wili pellet a haʻahaʻa ka puka. Eia naʻe, hiki ke hoʻopili ʻia nā ʻōpala liʻiliʻi ma hope o ka ʻoki ʻia ʻana. Inā ʻaʻohe kūlana paʻi, hiki ke hoʻohui ʻia he 70% o nā ʻāpana lāʻau a me 30% nā koʻu liʻiliʻi no ka hoʻohana ʻana. Pono e ʻoki ʻia nā ʻōpala nui ma mua o ka hoʻohana ʻana.

3. ʻO ke one polishing pauka i loko o nā hale hana papa a me nā hale hana hale: ʻo ka māmā kikoʻī o ke one polishing pauka he māmā, ʻaʻole maʻalahi ke komo ʻana i ka granulator, a ua maʻalahi ka pale ʻana i ka granulator, e hopena i ka haʻahaʻa haʻahaʻa; ma muli o ka māmā māmā o ke one polishing pauka, pono e hui pū me nā ʻāpana lāʻau a me ka granulate pū. Hiki i kēlā me kēia helu ma kahi o 50% e hoʻokō i ka hopena granulation.

4. ʻO nā koena o nā papa lāʻau a me nā ʻāpana lāʻau: Hiki ke hoʻohana ʻia nā koena o nā papa lāʻau a me nā ʻāpana lāʻau ma hope o ka ʻoki ʻia ʻana. Manaʻo ʻia e hoʻoheheʻe i ka nui o ka ʻāpana a hiki i ka laʻana o ka sawdust particle i ʻoki ʻia e ka band saw, e hoʻohana i ka pulverizer kiʻekiʻe, e hoʻohana i ka chip 4mm, paʻa ka puka ʻana, paʻa ka ʻāpana, kiʻekiʻe ka paʻakikī. emi ka ikehu.

5. Ua maloʻo ka mea maka: ua lilo ke kala i ʻeleʻele, ʻo ka lepo-e like me ka lepo i loaʻa i ka mildew koʻikoʻi, a ʻaʻole hiki ke paʻi ʻia i loko o nā mea waiwai granular kūpono. Ma hope o ka pulupulu, hoʻopau ʻia ka cellulose i loko o nā ʻāpana lāʻau e nā microorganism a ʻaʻole hiki ke paʻi ʻia i loko o nā ʻāpana maikaʻi. Inā pono e hoʻohana ʻia, pono e hoʻohui ʻia ma mua o 50% o nā ʻāpana lāʻau hou a hui pū. A i ʻole, ʻaʻole hiki ke paʻi ʻia i nā pellets kūpono.

6. Mea fibrous: Pono e hoʻomaluʻia ka lōʻihi o ka fiber no ka mea fibrous. ʻO ka maʻamau, ʻaʻole pono ka lōʻihi ma mua o 5mm. Inā lōʻihi loa ka fiber, e ālai maʻalahi ia i ka ʻōnaehana hānai a puhi i ke kaʻa o ka ʻōnaehana hānai. No nā mea fibrous, pono e hoʻomaluʻia ka lōʻihi o nā fiber. ʻO ka maʻamau, ʻaʻole pono ka lōʻihi ma mua o 5mm. ʻO ka hopena, ʻo ia ka hui ʻana ma kahi o 50% o nā ʻāpana lāʻau no ka hana ʻana, hiki ke pale pono i ka ʻōnaehana hānai mai ka hoʻopaʻa ʻana. ʻAʻohe o ka nui i hoʻohui ʻia, pono ʻoe e nānā mau inā paʻa ʻia ka ʻōnaehana. hewa, e pale aku i ka hiki ʻana mai o nā hewa e like me ke ahi a me ka hōʻino ʻana i ka motika o ka ʻōnaehana hānai.
