Floating Fish Feed Extruder Tshuab nthuav dav tus nqi qis dhau: Ua rau thiab kev daws teeb meem

Tus nqi qis qis hauv cov khoom extruder yog ib qho teeb meem zoo tshaj plaws uas tau ntsib thaum extrusion. Nws ua rau cov khoom uas muaj kev ntxhib los mos, saj tsis zoo, thiab lub neej luv luv, uas cuam tshuam rau cov neeg siv khoom txaus siab thiab cov khoom sib tw. Tsis tas li ntawd, nws ua rau cov khoom siv raw khoom pov tseg thiab cov nqi ntau lawm.

I. Cov Phenomena tshwj xeeb ntawm Kev nthuav dav tsis txaus

Phenomenon Description:

• Hard Texture & Tsawg Expansion:Cov khoom zoo li ntom thiab tawv, tsis muaj elasticity, thiab tsis tawg yooj yim thaum nias.
• Hauv qab -Expansion:Lub ntim nthuav dav yog qhov qis dua qhov xav tau, feem ntau hauv qab70%ntawm lub hom phiaj expansion.
• Poor Internal Structure:Cov khoom lag luam tsis muaj cov qauv honeycomb xav tau, muaj ob peb thiab tsis sib xws hauv qhov pores, ua rau muaj qhov sib txuam sib luag -section.
• Unexpanded Particles:Qee qhov xwm txheej, cov khoom siv raw khoom tseem muaj nyob hauv cov khoom, ua rau nws qhuav thiab tsis muaj crispness, tshwj xeeb tshaj yog cov khoom siv hmoov txhuv nplej siab xws lipob kwsthiabmov. Cov khoom no poob qis ntawm cov qauv kev nthuav dav uas yuav tsum tau ua thiab txo cov khoom lag luam zoo.

II. Cov laj thawj tseem ceeb ntawm kev nthuav dav tsis txaus

1. Raw Material Parameters tsis ua raws li cov qauv (45% ntawm cov ntaub ntawv)

• Cov dej noo ntau dhau:Cov khoom nyoos nrog cov ntsiab lus noo noo saum toj no15%nce viscosity tom qab cov hmoov txhuv nplej siab gelatinization, txo cov pa tawm thiab tiv thaiv kom txaus nthuav.
• Cov dej tsis txaus:Cov khoom nyoos nrog cov dej noo hauv qab no12%ua rau tsis zoo flowability thiab tsis sib npaug kub faib thaum lub sij hawm extrusion, uas nyob rau hauv lem tiv thaiv kom raug gelatinization thiab expansion.
• Tsis txaus Particle Loj:Cov ntaub ntawv nyoos uas tsis sib xws lossis dhau lawm - cov khoom loj tsis tuaj yeem ua tiav gelatinize hauv lub extruder, tiv thaiv kom tsis txhob nthuav dav.

2. Cov Khoom Raw Particle loj tsis txaus (45% ntawm cov ntaub ntawv)

• Loj Particles:Cov khoom uas loj dhau tsis tuaj yeem ua kom sov txaus thiab gelatinized hauv lub tshuab extrusion chamber, ua rau kev nthuav dav tsis tiav thiab cov khoom tsis zoo kawg.
• Tsis muaj Uniformity:Cov ntaub ntawv nyoos nrog qhov tsis sib xws ntawm qhov loj me ua rau qhov tsis sib xws ntawm cov cua sov, ua rau qee cov khoom tsis ua tiav, uas cuam tshuam ncaj qha rau qhov nthuav dav.

3. Tsis txaus Chamber Kub & Siab

• Underheated Chamber:Ua tsis tau preheat lub chamber los yog tswj lub chamber kub tsis sib haum, tiv thaiv cov khoom los ntawm ncav cuag qhov tsim nyog gelatinization kub.
• Qhov kub thiab txias:Qhov chaw pub mis yuav tsum yog80-100 degree, compression cheeb tsam120-150 degree, thiab thaj chaw puffing160-200 degree. Kev tswj tsis tau cov kab no tuaj yeem ua rau tsis tiav kev nthuav dav.
• Cov teeb meem khoom siv chav dej:Yog tias chav siab poob qis0.3 MPa rau, yuav tsis txaus siab nyob rau hauv lub chamber kom vaporize ya raws, uas ho txo ​​tus nqi expansion.

4. floating ntses pub pellet extruder tshuab Component Hnav los yog tsis tsim nyog Configuration

• Screw thiab lub tes tsho hnav:Hnav-tawm cov ntsia hlau lossis lub tes tsho txo ​​qis extrusion thiab shearing efficiency, tiv thaiv kom txaus crushing thiab gelatinization ntawm raw cov ntaub ntawv.
• Incorrect Die Orifice Size:Ib qho loj loj tuag orifice tuaj yeem tso siab sai heev, ua rau cov khoom poob nws lub peev xwm nthuav dav ua ntej nws tawm hauv qhov tuag.
• Lub sij hawm nyob tsis txaus:Kev nrawm nrawm ua rau lub sijhawm tsis txaus rau kev tsim nyog extrusion thiab gelatinization, uas cuam tshuam tsis zoo rau cov khoom kawg nthuav dav.

5. Cov txheej txheem tsis tsim nyog Parameter nqis

• Kev pub mis ntau dhau:Kev pub noj ceev ceev ua rau cov khoom siv raw khoom tsub zuj zuj hauv lub extruder, txo lub sij hawm kom zoo cua sov thiab extrusion, uas tiv thaiv kom txaus nthuav.
• Uneven Leavening Agent Ntxiv:Yog hais tias tus neeg sawv cev leavening tsis ntxiv kom zoo los yog tsis sib xws, nws ua rau kev nthuav dav tsis sib xws thiab tsis zoo puffing.
• Malfunctioning Cooling System:Lub tshuab txias txias tsis zoo yuav ua rau muaj cua sov ntau dhau ntawm qee qhov ntawm lub tshuab, scorching qee cov ntaub ntawv raw thaum lwm tus tsis nthuav dav, yog li cuam tshuam rau tag nrho qhov nthuav dav.

III. Cov kev daws teeb meem thiab ntev -Kev Tiv Thaiv Lub Sij Hawm rau Kev nthuav dav tsis txaus

1. Raw Material Management Optimization

• Screen thiab Crush Raw Materials:Ua ntej pub mis, xyuas kom meej tias cov khoom raw yog sib npaug zos (feem ntau dhau los ntawm a60-80 mesh sieve) thiab tsis muaj cov khoom loj lossis impurities.
• Moisture Control:Ntsuam xyuas thiab kho cov dej noo ntawm cov ntaub ntawv raw mus rau qhov zoo ntawm ntau yam12%-15%.
• Yog tias cov dej noo ntau dhau, ziab tuaj yeem ua kom txo tau nws.
• Yog tias cov dej noo tsawg dhau, txau dej thiab sib tov sib npaug.
• Leavening Agent Management:Xyuas kom muaj kev sib xyaw ua ke ntawm cov khoom siv raw thiab cov tshuaj leavening. Lub leavening neeg sawv cev yuav tsum muaj0.5%-2%ntawm raw khoom hnyav.

2. Floating ntses noj Pellet txiag tshuab Parameter hloov

• Preheating:Siab preheat lub extruder chamber ua ntej pib. Xyuas kom qhov kub thiab txias nyob rau hauv txhua cheeb tsam sib xws cov txheej txheem txheej txheem.
• Pub Zone: 80-100 degree
• Compression Zone: 120-150 degree
• Puffing Zone: 160-200 degree
• Chav Siab:Kho lub zog siab rau0.3-0.5 MPakom ruaj khov thiab qhuav chav, xyuas kom cov khoom ncav cuag qhov xav tau gelatinization kub.
• Ntsia Hlau Ceev:Ua kom cov ntsia hlau nrawm kom txuas ntxiv cov khoom siv lub sijhawm nyob hauv lub chamber, kom ntseeg tau tias txaus shearing thiab extrusion kom raug gelatinization.

3. Kev tu thiab cov khoom hloov pauv rau Floating Fish Feed Pellet Ua Tshuab

• Hnav Saib Xyuas:Tsis tu ncua xyuas qhov hnav thiab tsim kua muag ntawm cov khoom tseem ceeb, xws li cov ntsia hlau, lub tes tsho, thiab lub taub hau tuag. Hloov txhua qhov chaw uas hnav hnyav heev kom muaj kev ua haujlwm ntawm extrusion.
• Tuag Lub Taub Hau Loj:Xyuas kom lub cev tuag yog qhov tsim nyog rau qhov yuav tsum tau ua kom tsis txhob muaj kev tso tawm ntau dhau.
• Heating Elements & Temperature Controller:Tsis tu ncua tshuaj xyuas thiab hloov cov khoom cua sov puas lossis ua haujlwm tsis zoo ntawm cov tswj kub.

4. Kev ua kom zoo tshaj plaws thiab kev tswj hwm txhua hnub

• Pub ceev:Kho qhov ceev ceev kom haum rau cov ntsia hlau ceev thiab qhov ntsuas kub kom tsis txhob muaj cov khoom siv raw ntau dhau.
• Kev sim ntau lawm:Thaum siv cov qauv tshiab, ua me me - batch sim ua ntej ntau lawm kom ntseeg tau tias cov nyhuv puffing ua tau raws li qhov xav tau.
• Raw Material Testing:Teem ib lub kaw lus los kuaj qhov me me, cov ntsiab lus noo noo, thiab impurities ntawm raw khoom ua ntej siv. Tsuas yog siv cov khoom siv raw uas ua tau raws li cov txheej txheem teev tseg kom ntseeg tau tias kev nthuav dav zoo.
