Iwo makuru emhando mafomu anoumba biomass particle molding zvimedu zvemhando dzakasiyana siyana, uye hunhu hwekuzadza, kuyerera hunhu uye kudzvanya hunhu hwezvimedu panguva yekumanikidza kune pesvedzero huru pakumanikidza kuumbwa kwebiomass.

Biomass pellet compression molding yakakamurwa kuita nhanho mbiri.

Muchikamu chekutanga, munhanho yekutanga yekudzvanya, kudzvanywa kwepasi kunoendeswa kune iyo biomass mbishi, kuitira kuti yepakutanga yakasununguka yakarongedzerwa yakarongedzerwa dhizaini hurongwa hunotanga kushanduka, uye yemukati void ratio yebiomass inodzikira.

Muchikamu chechipiri, kana kudzvinyirirwa kunowedzera zvishoma nezvishoma, iyo yekumanikidza roller yemuchina webiomass pellet inopwanya zviyo zvakakura-zviyo pasi pekumanikidza, kushanduka kuita zvidimbu zvakapfava, uye deformation kana kuyerera kwepurasitiki kunoitika, zvimedu zvinotanga kuzadza iyo. voids, uye zvimedu zviri kuwedzera compact. Vanobatana pavanenge vachisangana nevhu, uye chikamu chekushushikana kwakasara kunochengetwa mukati mezvikamu zvakaumbwa, izvo zvinoita kuti kubatana pakati pezvikamu zvive zvakasimba.

Iyo yakatsetseka iyo mbishi zvinhu zvinoumba maumbirwo akaumbwa, iyo yakakwirira yekuzadza dhigirii pakati pezvimedu uye yakasimba yekubata; kana saizi yezvikamu zvidiki kune imwe nhanho (mazana kune akati wandei mamicrons), iyo yekubatanidza simba mukati mezvikamu zvakaumbwa uye yekutanga uye yechipiri kunyange ichachinja. Shanduko dzinoitika, uye kukwezva kwema molecular, electrostatic attraction, uye liquid phase adhesion (capillary force) pakati pezvimedu zvinotanga kusimuka kutonga.
Zvidzidzo zvakaratidza kuti kusamira uye hygroscopicity yezvimedu zvakaumbwa zvine hukama nehukuru hwezvikamu. Zvimedu zvine saizi diki ine nzvimbo yakakura chaiyo, uye zvimedu zvakaumbwa zviri nyore kutora hunyoro uye kuwanazve hunyoro. Diki, iyo voids pakati pezvimedu zviri nyore kuzadza, uye iyo compressibility inova yakakura, kuitira kuti yakasara yekushushikana kwemukati mukati mezvimedu zvakaumbwa inove idiki, nekudaro ichideredza hydrophilicity yeakaumbwa zvimedu uye kuvandudza kusamira kwemvura.

Muchidzidzo che particle deformation uye inosunga fomu panguva yekumisikidzwa kwezvidyarwa, iyo particle mechanical engineer yakaita microscope yekutarisa uye particle two-dimensional avhareji yeavhareji kuyerwa kwezvimedu zviri mukati mechivharo chekuumba, uye yakamisa chidimbu che microscopic chinosunga modhi. Mukutungamira kwekunyanya kunetseka kukuru, zvimedu zvinotambanudzira kune zvakatenderedza, uye zvimedu zvinosanganiswa nenzira yekubatana meshing; mugwara pamwe nekunyanya kushushikana kukuru, zvimedu zvinova zvitete uye zvinova maflakes, uye zvidimbu zvezvikamu zvinosanganiswa muchimiro chekubatana.

Zvinoenderana neiyi musanganiswa modhi, zvinogona kutsanangurwa kuti kupfava kwezvikamu zvebiomass mbishi, zviri nyore kuti maviri-dimensional avhareji dhayamita yezvikamu zvinova hombe, uye zviri nyore kuti biomass isimbiswe nekuumbwa. Apo mvura inenge iri mumiti yemiti yakanyanyisa, zvimedu hazvigoni kuwedzerwa zvakakwana, uye zvikamu zvakapoteredza hazvina kubatanidzwa zvakasimba, saka hazvigoni kuumbwa; kana mvura yemukati yakawandisa, kunyangwe zvimedu zvakazara munzira yakanangana nekunyanya kushushikana kukuru, Zvimedu zvinogona kusanganisirwa pamwe chete, asi sezvo mvura yakawanda iri mubibiti yakasimudzwa uye yakagovaniswa pakati pezvikamu zvezvikamu, iyo particle layers haigone kubatanidzwa zvakanyanya, saka haigone kuumbwa.

Zvinoenderana neruzivo ruzivo, mainjiniya akasarudzwa akasvika pakugumisa kuti zviri nani kudzora saizi yechinhu chakabikwa mukati mechikamu chimwe muzvitatu chedhayamita yefa, uye zviri muhupfu hwakatsetseka hazvifanirwe kunge zvakakwirira kudarika. 5%.
