Pfupiso yeVatungamiriri
Kugadzirwa kwenyama yemombe dzehuku muSaudi Arabia kwakasvika matani angangoita mamiriyoni 1.3 muna 2024, kuwedzera kwe12.9% gore negore zvichikonzerwa nemutemo weVision 2030 wekuchengetedza chikafu wakanangana ne80% yekuzvigadzirira huku (GASTAT, 2024). Kuwedzera uku kunoisa kudiwa kukuru kune vagadziri vezvikafu, kunyanya munguva yezhizha apo tembiricha yemhepo inowanzopfuura 45°C. Al-Riyadh Feed Industries (zita risingazivikanwe nechikumbiro chevatengi), imwe yemakambani mashanu epamusoro ekugadzira nyama dzehuku dzakabatanidzwa muUmambo ane huwandu hwechikafu chegore negore chinodarika matani 280,000, yakatarisana nedambudziko guru rekugadzira: kugara kwenguva refu kwepellet kwakaramba kuchiderera panguva yekupisa kwaMay-Gunyana, kuchidzika kusvika pa91-92% PDI (Pellet Durability Index) zvichienzaniswa nechiyero chemukati chekambani che ≥96%.
Pakati pa2024, kambani yakagadzirisa mitsetse yayo miviri mikuru yepellet mill neHongyang HYPM-series ring die assemblies uye matched roller shells. Mukati memazuva makumi mapfumbamwe ekutanga ekushanda kusvika panguva yekupisa kukuru, mitsetse iyi yakawana PDI yakagara kwenguva refu ye98.2% (± 0.5), yakabvisa zviitiko zvekudzipwa nekupisa, uye yakaderedza frequency yekutsiva ring die neinenge 35% zvichienzaniswa nemafuta aimboshandiswa muEurope. Chidzidzo ichi chinoongorora matambudziko ehunyanzvi ekupisa kwakanyanya, mhinduro yeinjiniya yeHongyang, uye mhedzisiro inogona kuverengerwa yakawanikwa.
Nhoroondo yeIndasitiri neVatengi
Saudi Arabia inoshanda pasi peimwe yenzvimbo dzinopisa zvikuru pasi rose dzekurima zvipfuyo zvakanyanya. General Authority for Statistics yakashuma kuti dunhu reRiyadh rega rakagadzira matani 359,700 enyama yenyama yebroiler muna 2024, ichiteverwa neHail (matani 295,000) neQassim (matani 200,000). Chikafu chemhuka chinomiririra 60-70% yemari yese yekugadzira nyama yemombe, zvichiita kuti mhando yepellet ive shanduko huru yehupfumi.
Al-Riyadh Feed Industries ine minda mitatu yekudyisa mhuka iri mudunhu repakati ichipa chikafu kumapurazi enyama makumi mana nemaviri akabvumiranwa. Musanganiswa wavo mukuru wekugadzira nyama yenyama ndeyechibage-soya ine dhayamita ye3.0 mm pellet, ichitarisa tembiricha yenyama yemombe iri pasi pe88°C panotonhorera. Hongyang isati yatanga kugadzira, kambani iyi yainetseka nemwaka wayo unogara uchichinja: sezvo tembiricha yemhepo yaikwira kupfuura 38°C (kazhinji pakutanga kwaMay), mitoro yemota dzemapellet mill yakava isina kugadzikana, tembiricha yepamusoro yakakwira kupfuura 95°C, uye PDI yepellet yakapera yakaderera pasi pe96% inodiwa kuchengetedza mwero wekurasikirwa kwechikafu padanho repurazi.
Mugumisiro wezvehupfumi waive wakaenzana. Ruzivo rweindasitiri kubva kuInternational Poultry Research Institute runoratidza kuti kuderera kwega kwega kwe1% muPDI kunoenderana nekuwedzera kwe0.4-0.6% mukurasikirwa kwechikafu mumasisitimu ekudyisa chikafu mupan - zvichireva kuti matani angangoita 1,100-1,700 ekuwedzera kwechikafu anorasika gore rega rega pachikero cheAl-Riyadh apo PDI yaidzikira nemwaka.
Dambudziko: Kupisa kwakanyanya uye kuora kwemhando yepellet
Kudya kwenyama yemombe dzehuku kunoshanda mukati mehwindo rakamanikana rethermodynamic. Tembiricha yakanaka yekudzikisa mash iri pakati pe75-90°C, uye tembiricha yekubuda kwayo inochengetwa kusvika 80-90°C. Pamusoro pe95°C, kudzikira kwekupisa kwemavhitamini (A, D, E, K) uye maamino acids ekugadzira (lysine, methionine) kunokurumidza kuyerwa. Panguva imwe chete, Maillard reaction pakati pekuderedza shuga nemaamino acids emahara inotanga kubatanidza lysine muzvinhu zvisingagayike, zvichideredza huwandu hwezvinovaka muviri huripo (Journal of Applied Poultry Research, 2019).
Pamigayo yeAl-Riyadh, kupisa kwezhizha kwakaunza nzira nhatu dzekugadzirisa kutadza:
1. Kusakwana kwesimba rekutonhodza: Mhepo inodziya pa45°C yakaderedza kupisa kwemuchina unotonhodza, zvichiita kuti mapellets asasvike patembiricha yekubuda kwe5°C pamusoro penzvimbo. Mapellets anobuda pakupisa kwakanyanya anochengetedza hunyoro hwasara uye akapfava panguva yekuchengetera.
2. Kupisa kwechinhu chinopisa: Pakupisa kwe45°C kwakaramba kuripo, simba rekupisa remuchina wepellet rakapfuudzwa. Kupisa kwechinhu chinopisa kwakakwira kupfuura 95°C mukati memaminitsi makumi mana nemashanu ekutanga ekushanda nguva dzose, zvikaita kuti pave nekudzima otomatiki pa PLC yekuchengetedza yemuchina.
3. Kutsvedza kweroller shell: Kupisa kwakanyanya kwakaderedza kushanda kwe friction coefficient pakati pe roller shell pamusoro uye conditioned mash, zvichikonzera intermittent roller slippage, kusaenzana kwezvinhu kupararira kumeso kwe die, uye ma die wear patterns.
Mhedzisiro yacho yese: pellet PDI yakaderera kusvika pa91.2% (yakayerwa nenzira yeASAE S269.4 tumbling), kutambisa chikafu mumapurazi kwakawedzera neinenge 2.8%, uye chirimwa chakamanikidzwa kuderedza simba rezvirimwa ne15-20% munguva dzinopisa zvikuru kudzivirira kuvharwa. Hupenyu hwebasa re "ring die" - hwakatove hwakamanikidzwa ne "silica" muchibage chinobva munharaunda - hwakaderera kubva paavhareji yemaawa ekushanda e3,500 muchando kusvika kumaawa e2,200-2,500 muzhizha.
Hongyang Solution
Mushure meongororo yehunyanzvi yakaitwa pamwe chete nechikwata cheinjiniya cheHongyang, kugadziriswa kwezvikamu zvitatu kwakaitwa pamitsetse miviri yemigodhi yepellet:
1. Ring Die Yakagadzirwa Nemhando Yepamusoro Ine Chiyero Chekudzvanya Chakanaka
Hongyang akataura nezve 3.0 mm dhayamita ring die ine compression ratio ye1:12.5 — yakarongwa kuti ishandiswe nevatengi kugadzira broiler finisher (chibage-soybean meal base ine 3.2% yakawedzerwa mafuta uye 14.5% target post-conditioning moisture). Chinhu chakagadzirwa ne die chaive X46Cr13 (DIN 1.4034 / Chinese 4Cr13) martensitic stainless steel, yakagadzirwa kuburikidza ne vacuum hardening pa1,050-1,080°C ichiteverwa ne double tempering pa220-240°C kuti pave nekuomarara kwakafanana kweHRC 52-54 mu die track yese.
Zvakakosha, tekinoroji yeHongyang yekuboorwa kwegomba remadhiraivha yakaboorwa nepfuti — ichishandisa CNC deep-hole drilling ine ±0.02 mm positional tolerance — yakagadzira kufanana kwedhayamita yegomba kubva kune rimwe kuenda kune rimwe yakayerwa pa ≤15 μm variance. Iyi level yekunyatsojeka inoderedza differential flow resistance kumeso kwedhiraivha, chinhu chakakosha mukuchengetedza denderedzwa remadhiraivha epellet panguva yekupisa kunochinja-chinja. Die hole inlet yega yega yaipedzwa ne tapered lead-in chamfer pa 60° kuderedza resistance yekupinda kwezvinhu, zvichideredza simba rinoshandiswa (kWh/ton) rinodiwa kutanga kugadzirwa kwedhiraivha.
2. Musangano weRoller Shell wakabatana une Kugadziriswa kweBearing yekupisa kwakanyanya
Hongyang akapa seti yemagoko eroller akaenzana akagadzirwa nesimbi ye20CrMnTi alloy ine kudzika kwekaburi ye2.0-2.2 mm uye kuomarara kwepamusoro kweHRC 60-62. Patani yecorrugation yakagadzirwa ne 1.2 mm groove pitch uye 0.8 mm groove depth, yakagadziriswa kuti ikwanise kubata zvinhu zvakanyanya mu broiler mash ine mafuta akawanda uye ine low-friction.
Musanganiswa weroller waisanganisira mabheya eroller ane jira rakapfava rakavharika (SKF Explorer-class equivalent, rated to 120°C continuous operating temperature), achitsiva mabheya akajairwa akanga aratidza kuputsika kwemafuta uye kupararira kwemvura panguva yekugadzira kwezhizha. Chisimbiso chine jira rakapfava chine zvinhu zvePTFE lip chakadzivirira kupinda kwemafuta, chinhu chinowanzo kanganisa kana chidimbu chinopisa, chakaoma chikapinda muzvikamu zvemabheya.
3. Die-Roller Gap Calibration Protocol
Chikwata chehunyanzvi chaHongyang chakagadzira mukaha we 0.40 mm (± 0.05 mm), wakayerwa uchitonhora ne feeler gauge panzvimbo nhanhatu dzakaenzana dzakatenderedza denderedzwa re die. Iyi mukaha wakasimba kupfuura westandard unotsiva kuwedzera kwekupisa pakupisa kwekushanda: pa 85°C die surface tembiricha, X46Cr13 die inowedzera ne radially neinenge 0.08-0.12 mm (coefficient yekuwedzera kwekupisa ≈10.5 × 10⁻⁶/K), zvichinyatsovhara mukaha wechando kusvika pa 0.28-0.35 mm pakushanda. Iyi nzira ye pre-compensation inodzivirira mukaha kuti usanyanya kupararira panguva yezhizha, izvo zvaizoderedza simba rekumanikidza pa mash uye kukanganisa huwandu hwe pellet.
