Iwo makuru ezvinyorwa mafomu anoumba biomass particle molding zvimedu zveakasiyana masikisi, 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 yekumanikidza, iyo yakaderera kudzvanywa inoendeswa kune iyo biomass mbishi zvinhu, 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 ezvimedu, 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 zvakare.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 yezvikamu zvakaumbwa zvine hukama nehukuru hwezvikamu.Zvimedu zvine saizi diki ine nzvimbo yakakura chaiyo, uye zvimedu zvakaumbwa zviri nyore kutora unyoro uye kuwanazve hunyoro.Diki, iyo voids pakati pezvimedu zviri nyore kuzadza, uye iyo compressibility inova yakakura, kuitira kuti kusara kwemukati kushushikana mukati mezvimedu zvakaumbwa kuve kudiki, nekudaro kunetesa 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;mukutungamira 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 zvinokura, uye zviri nyore kuti biomass isimbiswe nekuumbwa.Apo mvura inenge iri mumiti yemiti yakaderera zvikuru, zvimedu hazvigoni kuwedzerwa zvakakwana, uye zvikamu zvakapoteredza hazvina kubatanidzwa zvakasimba, saka hazvigoni kuumbwa;kana mvura yemukati yakawandisa, kunyangwe zvimedu zvakazara munzira inoenda kune yakanyanya kushushikana kukuru, Zvimedu zvinogona kusanganisirwa pamwe chete, asi sezvo mvura yakawanda iri mubibiti inoburitswa uye ichigoverwa pakati pezvikamu zvezvikamu, iyo particle layers haigone kubatanidzwa zvakanyanya, saka haigone kuumbwa.

Zvinoenderana neruzivo ruzivo, mainjiniya akagadzwa akasvika pamhedzisiro yekuti zviri nani kudzora saizi yezvakagadzirwa mukati mechikamu chimwe muzvitatu chedhayamita yefa, uye zvirimo muhupfu hwakatsetseka hazvifanirwe kunge zvakakwirira kudarika. 5%.
