1. Dab tsi 4 mm Qhuav -Type Test Verifies
Lub 4 hli qhuav- hom dev zaub mov ua tshuab kuaj ua haujlwm lub tshuab extruder nrog tus tsiaj tiag- cov qauv zaub mov los xyuaspellet loj qhov tseeb, extrusion stability, pellet kev ntxhib los mos thiab kev ua haujlwm tas lirau 4 hli pellets ua ntej xa khoom.
2. Vim li cas 4 mm Pellet Test Matters
Pellet loj ncaj qha cuam tshuam rau tus tsiaj zom tus cwj pwm, kev zom zaub mov zoo, kev lees txais pub thiab ntim khoom sib xws.
4 hli pellets yog siv rau nruab nrab- cov khoom noj dev loj, cov menyuam yaus noj zaub mov thiab cov tsiaj qhuav sib npaug- khoom noj khoom haus.
3. Txoj Kev Qhuav -Tom Qauv Cai
Ib qho qhuav- hom tsiaj tsiaj extruder sivmechanical kev sib txhuam thiab siablos tsim kom muaj cua sov thaum lub sij hawm extrusion - tsis muaj sab nraud chav boiler system. Cov yam ntxwv: cov qauv yooj yim dua, cov nqi peev qis dua, kev tsim khoom tsim khoom sib cog lus - haum rau cov tsiaj me thiab nruab nrab- khoom noj khoom haus.
4. Rau -Cov txheej txheem xeem
- Raw khoom npaj:pob kws hmoov, soybean pluas mov, nqaij hmoov, ntses pluas noj, vitamin premix; check hmoov fineness, noo noo tshuav nyiaj li cas, cov mis sib xws.
- Pub stability:smooth feeding flow, tsis muaj blockage, ruaj khov ntsia hlau thauj ceev.
- Extrusion siab:compression thiab kev sib txhuam kub; saib xyuas kev ruaj ntseg siab, kub sib xws, nthuav tus cwj pwm.
- 4 hli pellet forming:txoj kab uas hla raug, roundness, nto smoothness, structural sib xws.
- Dryness thiab hardness:hardness sib npaug, tawg tsis kam, noo noo stability.
- Kev khiav tsis tu ncua:lub cev muaj zog kub stability, extrusion continuity, tso zis sib xws, ntsia hlau coj cwj pwm.
5. Qhuav vs ntub Extrusion
| Yam | Hom qhuav | Hom ntub dej |
|---|---|---|
| Thaum tshav kub kub | Kev sib txhuam/siab | Chav txias + kev sib txhuam |
| Boiler | Tsis xav tau | Yuav tsum tau |
| Kev nqis peev | qis | Siab dua |
| Starch gelatinization | Nruab nrab | Siab dua (zoo dua nthuav dav / digestibility) |
| Zoo tshaj plaws | Cov kab me me / nruab nrab | Nruab nrab / loj ntau lawm |
6. Kab hauv qab
Cov qhuav- hom 4 mm extruder yog qhov qis - nqis peev nkag rau cov tsiaj me thiab nruab nrab- cov neeg tsim khoom noj: tsis muaj chav boiler, compact hneev taw thiab txhim khu kev qha pellet zoo thaum kuaj thiab ua haujlwm kom raug. Rau siab dua gelatinization thiab tso zis, ntub - hom tshuab ua pov thawj lawv cov nqi ntxiv.
