Ngokukhuthazwa kunye nokusetyenziswa kwesondlo se-pellet kwimfuyo kunye neenkukhu, imboni ye-aquaculture, kunye namashishini asakhulayo afana nesichumisi esihlanganisiweyo, i-hops, i-chrysanthemum, i-chips yenkuni, i-peanut shells, kunye ne-cottonseed meal, iiyunithi ezininzi ngakumbi zisebenzisa i-ring die pellet mills. Ngenxa yokwahluka kwefomula yesondlo kunye nomahluko wengingqi, abasebenzisi baneemfuno ezahlukeneyo zefidi yeepellet. Umenzi wesondlo ngamnye ufuna umgangatho olungileyo wepellet kunye nowona mgangatho uphezulu wokupelitha kwifidi yeepellet eziyivelisayo. Ngenxa yeefomyula zefidi ezahlukeneyo, ukukhethwa kweeparamitha zokufa kweringi xa ucinezela ezi feed pellet ukwahluka. Iiparamitha zibonakaliswa ikakhulu ekukhethweni kwezinto eziphathekayo, i-pore diameter, i-pore shape, i-aspect ratio, kunye nomlinganiselo wokuvula. Ukukhethwa kweeparamitha zokufa kweringi kufuneka kumiselwe ngokokwakheka kweekhemikhali kunye neempawu ezibonakalayo zezinto ezahlukeneyo ekrwada ezenza ifomyula yokutya. Ukwakhiwa kweekhemikhali zezinto eziluhlaza kubandakanya iprotheni, isitashi, amafutha, i-cellulose, njl. njl.

Ukutya kwemfuyo kunye neenkukhu ikakhulu kuqulethe ingqolowa kunye nombona, kunye nomxholo ophezulu westatshi kunye nomxholo ophantsi wefayibha. Kukutya okunesitatshi esiphezulu. Ukucofa olu hlobo lokutya, kufuneka kuqinisekiswe ukuba isitashi sigcwele i-gelatinized kwaye sihlangabezane nobushushu obuphezulu kunye neemeko zokucubungula. Ubukhulu bomsesane wokufa ngokuqhelekileyo bubunzima, kunye nokuvula Uluhlu lubanzi, kwaye umlinganiselo we-spectional uphakathi kwe-1: 8-1: 10. Iinkukhu zebroiler kunye namadada kukutya okune-eneji ephezulu kunye nomxholo ophezulu wamafutha, igranulation elula, kunye nobude besiqingatha esikhulu kunye nobukhulu phakathi kwe-1:13.

Ukutya kwasemanzini ikakhulu kubandakanya ukutya kwentlanzi, ukutya kwe shrimps, ukutya kofudo oluthambileyo, njl njl. -iprotheni yokutya. Izinto zasemanzini zifuna uzinzo lwexesha elide lwamasuntswana emanzini, idiameter engaguqukiyo kunye nobude obucocekileyo, obufuna ubungakanani bamasuntswana acolekileyo kunye neqondo eliphezulu lokuvuthwa xa izinto zigranyuliwe, kwaye iinkqubo zangaphambi kokuvuthwa nasemva kokuvuthwa zisetyenziswa. Ububanzi bokufa kwendandatho esetyenziselwa ukutya kweentlanzi ngokuqhelekileyo phakathi kwe-1.5-3.5, kwaye uluhlu lwe-spection ratio luphakathi kwe-1: 10-1: 12. Uluhlu lwe-aperture ye-ring ring esetyenziselwa ukutya kwe-shrimp phakathi kwe-1.5-2.5, kunye nobude bobude ukuya kwi-diameter ratio buphakathi kwe-1: 11-1: 20. Iiparameters ezithile zomlinganiselo wobude ukuya ku-diameter zikhethiwe Kufuneka kunqunywe ngokwezibonakaliso zesondlo kwifomula kunye neemfuno zabasebenzisi. Kwangaxeshanye, uyilo lwemilo yomngxuma wokufa ayisebenzisi imingxuma enyathelweyo kangangoko kunokwenzeka phantsi kwemeko yokuvumela amandla, ukuze kuqinisekiswe ukuba amasuntswana esikiweyo anobude obufanayo kunye nobubanzi.

Ifomula yesichumisi esihlanganisiweyo ikakhulu inesichumisi esingaphiliyo, isichumisi esiphilayo kunye neeminerali. Izichumisi ezingaphiliyo kwizichumisi ezidibeneyo ezifana ne-urea zigqwesa ngakumbi kwi-ring ring, ngelixa iiminerali ziyingozi kakhulu kumngxuma wokufa kunye nomngxuma wangaphakathi we-cone we-ring die, kwaye amandla e-extrusion aphezulu kakhulu. enkulu. Ububanzi bomngxuma we-compound yesichumiso sokufa bukhulu ngokubanzi, ukusuka kwi-3 ukuya kwi-6. Ngenxa ye-coefficient yokunxiba enkulu, umngxuma wokufa kunzima ukuwukhupha, ngoko ke umlinganiselo wobude ukuya kububanzi buncinci, ngokubanzi phakathi kwe-1: 4 -1 : 6 . Isichumisi siqulethe ibhaktheriya, kwaye iqondo lokushisa akufanele lidlule i-50-60 degrees, ngaphandle koko kulula ukubulala ibhaktheriya. Ke ngoko, isichumiso esihlanganisiweyo sidinga ubushushu obuphantsi begranulation, kwaye ubukhulu becala ubukhulu bodonga lweringi buncinci. Ngenxa yokuguga okuqatha kunye nokukrazuka kwesichumisi esidityanisiweyo kumngxuma wokufa weringi, iimfuno kwidayamitha yomngxuma azikho ngqongqo kakhulu. Ngokuqhelekileyo, i-ring die ichithwe xa i-gap phakathi kwee-roller zoxinzelelo ayikwazi ukulungiswa. Ngoko ke, ubude bomngxuma onyathelweyo busetyenziselwa ukuqinisekisa umlinganiselo we-aspect ratio kunye nokuphucula ubomi bokugqibela benkonzo ye-ring die.

Umxholo wefiber ekrwada kwiihops uphezulu kwaye uqulathe iingxaki, kwaye iqondo lobushushu alinakudlula idigri ezingama-50, ngoko ke ubukhulu bodonga lweringi bufa ngenxa yokucinezela iihops buncinci, kwaye ubude kunye nobubanzi bufutshane, ngokubanzi malunga ne-1: I-5, kunye ne-particle diameter inkulu kwi-5-6 phakathi.

I-Chrysanthemum, amaqokobhe e-peanut, ukutya kwe-cottonseed, kunye ne-sawdust iqulethe isixa esikhulu sefayibha ekrwada, umxholo wefiber ekrwada ungaphezulu kwe-20%, umxholo we-oyile uphantsi, ukuxhathisa kokukhuhlana kwezinto ezidlula kumngxuma wokufa kukhulu, igranulation. ukusebenza kumbi, kwaye ubulukhuni begranules bufuneka. Ephantsi, kunzima ukuhlangabezana neemfuno ukuba inokubunjwa ngokubanzi, i-particle diameter ikhulu kakhulu, ngokubanzi phakathi kwe-6-8, kunye ne-aspect ratio ngokubanzi malunga ne-1: 4-1: 6. Ngenxa yokuba olu hlobo lokutya lunoxinano oluncinci lwesambuku kunye nobubanzi obukhulu bomngxuma wokufa, iteyiphu kufuneka isetyenziswe ukutywina isangqa sangaphandle sendawo yomngxuma wokufa ngaphambi kwegranulation, ukuze izinto zizaliswe ngokupheleleyo kumngxuma wokufa kwaye zenziwe. , kwaye ke iteyiphu iyakrazulwa.

Xa kusenziwa igranulation yezixhobo ezahlukahlukeneyo, imfundiso yonqulo ayinakulandelwa ngqongqo. Kuyimfuneko ukuba ukhethe iiparamitha ezichanekileyo zokufa kweringi kunye neemeko zokusebenza ngokweempawu zegranulation zezinto kunye neempawu ezithile zomenzi ngamnye wokutya. Kuphela ngokuziqhelanisa neemeko zasekuhlaleni kunokuveliswa ukutya okukumgangatho ophezulu.

Uhlalutyo lwesizathu kunye neNdlela yoPhuculo lweNcam ezingaqhelekanga

Iiyunithi zemveliso yokutya zihlala zineepellets ezingaqhelekanga xa zivelisa ukutya, okuchaphazela inkangeleko kunye nomgangatho wangaphakathi weepellets, oko kuchaphazela ukuthengiswa kunye nodumo lwefektri yokutya. Oku kulandelayo luhlu lwezizathu zamasuntswana angaqhelekanga ahlala esenzeka kwiindawo zokusila kunye noluhlu lweendlela zokuphucula ezicetyiswayo:
