Kev tswj xyuas meej ntawm buoyancy thiab dab dej ua rau nws tsim nyog rau kev ua liaj ua teb ntses thoob plaws txhua qib dej. Lub tshuab ua zaub mov ntub dej tuaj yeem ua tau yooj yim tsim peb hom pub- ntab, dab dej, thiab ib nrab- ntab- los ntawm kev kho tus nqi ntawm chav ntxiv, ntsia hlau ceev, thiab extrusion siab. Cov khoom buoyancy thiab sinking stability deb tshaj ntawm cov extruders qhuav. Thaum tsim cov khoom noj ntab, chav dej ua kom muaj kev sib txuam ntau dua ntawm cov khoom siv raw, stabilizing cov qauv hauv qhov pore ntawm cov khoom, ua tiav cov buoyancy tus nqi ntau dua 95%. Cov zaub mov tuaj yeem nyob twj ywm ntawm qhov dej rau 8-12 teev yam tsis muaj kev tawg, ua rau nws haum rau nruab nrab- mus rau-sab saum toj- qib ntses xws li ntses bass thaj tsam thiab tilapia. Thaum tsim cov khoom noj dab dej, qhov extrusion siab thiab cov pa ntxiv tuaj yeem txo qis, tswj cov particle ntom ntawm 1.1-1.3 g / cm³, tso cai rau nws maj mam ntws mus rau hauv qab, ua rau nws haum rau hauv qab-cov ntses xws li nyom carp thiab cov carp. Tsis tas li ntawd, nws cov dej tsis kam yog 10% -15% siab dua li cov extruder qhuav. Piv nrog rau qhov tsawg precision ntawm buoyancy thiab sinking tswj thiab lub siab nyiam rau "semi-floating, semi-sinking" tshwm sim nyob rau hauv qhuav extruders, ntub extruders muaj ntau dua cov khoom sib xws thiab muaj peev xwm ua tau raws li tus cwj pwm pub mis ntawm ntau hom ntses.

Optimizing pellet hardness thiab palatability kom haum rau ntau theem aquaculture. Qhov qis -kub extrusion thiab cov txheej txheem humidification ntawm cov ntses ntub dej extruder tshuab tso cai rau kev tswj tau yooj yim ntawm pellet hardness ntawm 1.5-4 kg, ua tau raws li qhov xav tau ntawm cov theem sib txawv ntawm cov aquaculture theem ntawm kib rau cov neeg laus ntses. Thaum tsim cov khoom noj kib, lub siab extrusion thiab kub tuaj yeem txo los tswj cov pellet hardness ntawm 1.5-2 kg, uas ua rau cov ntaub ntawv xoob uas yooj yim zom thiab zom, tsis txhob muaj kev puas tsuaj rau lub qhov ncauj. Thaum tsim cov ntses pub rau cov neeg laus, lub siab extrusion yog nce, kho lub hardness mus rau 3-4 kg, txhim khu lub pellet lub chewability thiab dej tsis kam. Nyob rau tib lub sijhawm, chav humidification ua kom muaj kev sib xyaw ua ke ntawm cov khoom siv raw, ua rau cov pellet du nto thiab cov qauv compact, txo tus nqi tawg (tsawg dua lossis sib npaug li 3%). Piv nrog rau cov khoom siv extruder qhuav (kev tawg tus nqi 5% -8%), pub cov khoom pov tseg yog txo los ntawm ntau tshaj 40%. Tsis tas li ntawd, lub tshuab ua haujlwm maj mam khaws cov khoom qub ntawm cov khoom siv raw, txhim kho kev noj zaub mov kom zoo thiab nce kev noj zaub mov ntau dua 95% rau cov tsiaj ua liaj ua teb.

Cov pellets muaj kev ruaj ntseg siab, ncua lawv lub sijhawm cia thiab siv sijhawm. Cov khoom noj pellets ua los ntawm cov tshuab ntub dej ntub dej muaj cov qauv sib xws thiab cov dej noo ruaj khov (12%-14%). Tsawg-kev ua haujlwm kub txo cov roj oxidation ntawm cov pellet nto, ua rau lawv tsis tshua muaj pwm thiab clumping thaum lub sij hawm cia, ncua lawv lub neej txee los ntawm 1-2 lub hlis piv rau cov khoom extruder qhuav. Hauv aquaculture, lawv cov dej ua haujlwm zoo heev txo cov khoom noj khoom haus thiab dej paug, txo cov nqi dej huv. Piv txwv li, nyob rau hauv high-density aquaculture, siv sinking pub uas tsim los ntawm ntub extruders yuav txo tau ammonia nitrogen theem nyob rau hauv dej los ntawm ntau tshaj 20%, thaum tseem txo tau cov khoom pov tseg thiab txhim kho tag nrho aquaculture efficiency. Cov txiaj ntsig zoo ntawm lub cev no ua rau cov ntses ntub dej pellet ua tshuab ua cov khoom siv rau cov khoom noj hauv dej.

hais txog peb

MIKIM cov ntses pub pellet cov kab ntau lawm thiab cov tshuab txhawb nqa muaj txiaj ntsig zoo rau cov nyiaj. Tsis yog lawv pheej yig xwb, tshem tawm cov neeg lag luam nruab nrab thiab tso cai rau me thiab nruab nrab- cov lag luam me (SMEs) thiab cov neeg ua liaj ua teb ntses los yuav cov khoom ua tiav ntawm tus nqi tsim nyog, tab sis lawv kuj khav theeb tshwj xeeb. Cov txheej txheem automated tag nrho, los ntawm cov khoom siv raw crushing thiab meej cov khoom sib xyaw rau extrusion pelleting thiab maturation, yog ua tiav nyob rau hauv ib tug nruam ntws. Qhov no ua rau muaj cov hmoov txhuv nplej siab gelatinization thiab cov txheej txheem pellet zoo, txhim kho kev tsim khoom thiab kev noj zaub mov zoo, ua tiav "tus nqi qis, siab tso zis." Xaiv MIKIM ntses pub pellet ntau lawm kab txhais tau hais tias muaj kev txaus siab ua ntej- muag thiab tom qab- kev muag khoom, suav nrog 24-teev kev txhawb nqa cov neeg siv khoom hauv online, ib- xyoo lav rau tag nrho lub tshuab, kev teeb tsa hauv chaw, commissioning, thiab kev saib xyuas, thiab cov khoom seem ruaj khov. Cov neeg siv khoom tuaj yeem yuav nrog kev ntseeg siab thiab siv nrog kev thaj yeeb ntawm lub siab, nrog rau cov nqi zoo thiab kev pabcuam zoo !!!
