Njira Yopangira Margarine China Manufacturer

Kanema Wopanga:https://www.youtube.com/watch?v=Zar71w0TUzM 

Kupanga margarine kumaphatikizapo magawo awiri: kukonza zinthu zopangira ndi kuziziritsa ndi pulasitiki. Zipangizo zazikulu zimaphatikizapo matanki okonzekera, HP pump, votator (scraped surface heat exchanger), pin rotor machine, firiji unit, margarine filling machine ndi zina zotero.

Njira yoyamba ndi kusakaniza gawo la mafuta ndi gawo la madzi, muyeso ndi kusakaniza kwa gawo la mafuta ndi gawo la madzi, kuti akonze chakudya cha zinthuzo kuti zigwiritsidwe ntchito pomaliza. Njira yomaliza ndi kuziziritsa pulasitiki mosalekeza ndi kulongedza zinthu.

Njira yokonzekera margarine ikuwonetsedwa pa Chithunzi 1:

1. 1.Mkaka wofufumitsa

Fomula ina ya margarine yowonjezera mkaka, ndi mkaka pambuyo pa kuyaka kwa lactic acid mabakiteriya ukhoza kupanga kukoma kofanana kwa kirimu wachilengedwe, kotero kuti fakitaleyo imapanga mkaka wofufumitsa ndi madzi osakaniza.

1. 2.Kusakaniza madzi

Madzi ndi zowonjezera zosungunuka m'madzi zomwe zili mu fomula ya margarine, monga mkaka woviikidwa, mchere, zosungira, ndi zina zotero, zimawonjezeredwa ku kusakaniza kwa gawo la madzi ndi thanki yoyezera muyeso wokhazikika kuti zisakanizidwe, kotero kuti zigawo za gawo la madzi zisungunuke kukhala yankho lofanana.

1. 3.Kusakaniza gawo la mafuta

Mafuta osaphika okhala ndi mawonekedwe osiyanasiyana amasakanizidwa kaye mu thanki yosakanizira mafuta malinga ndi kuchuluka komwe kwaperekedwa, kenako zowonjezera zosungunuka ndi mafuta, monga emulsifier, antioxidant, pigment yosungunuka ndi mafuta, cellulose yosungunuka ndi mafuta, ndi zina zotero, zimawonjezedwa ku gawo la mafuta malinga ndi kuchuluka kwake, kusakanikirana ndi thanki yoyezera, ndikusakanizidwa kuti apange gawo la mafuta lofanana.

1. 4.Emulsion

Cholinga cha emulsification ya margarine ndikupanga gawo lamadzi kukhala lofanana komanso lokhazikika mu gawo la mafuta, ndipo kuchuluka kwa kufalikira kwa gawo lamadzi kumakhudza kwambiri ubwino wa chinthucho. Chifukwa kukoma kwa margarine kumagwirizana kwambiri ndi kukula kwa tinthu ta madzi, kufalikira kwa tizilombo toyambitsa matenda kumachitika mu gawo la madzi, kukula kwa mabakiteriya ambiri ndi 1-5 microns, kotero madontho amadzi mu 10-20 microns kapena mocheperako amatha kuchepetsa kufalikira kwa mabakiteriya, kotero kufalikira kwa gawo la madzi kumakhala kocheperako, tinthu ta madzi ndi tating'ono kwambiri kungapangitse margarine kutaya kukoma; Kufalikira sikokwanira, tinthu ta madzi ndi tating'ono kwambiri, kungapangitse margarine kukhala woipa. Ubale pakati pa kuchuluka kwa kufalikira kwa gawo lamadzi mu margarine ndi mtundu wa chinthucho ndi motere:

Zitha kuwoneka kuti ntchito ya emulsification iyenera kufikira pamlingo winawake wofunikira pakufalikira.

Cholinga chosakaniza gawo la madzi ndi gawo la mafuta padera komanso mofanana ndi gawo lapitalo ndikuwonetsetsa kuti emulsion yonse ikugwirizana bwino pambuyo pa emulsification ndi kusakaniza magawo awiri a mafuta ndi madzi. Kusakaniza kwa emulsification ndi, vuto la ntchito ndi madigiri 50-60, gawo la madzi limawonjezeredwa ku gawo loyezedwa la mafuta, mu makina osakaniza kapena kupompa, kusakaniza ndi gawo la madzi lomwe limafalikira mokwanira mu gawo la mafuta, kupanga latex. Koma mtundu uwu wa latex wamadzimadzi ndi wosakhazikika kwambiri, kusakaniza koyima kungakhale pa malo osewerera mafuta ndi madzi kulekanitsidwa.

Pambuyo poti emulsion yosakanikirana yaperekedwa, njira yozizira ndi pulasitiki imachitika mpaka chinthucho chitapakidwa.

Emulsion iyenera kuziziritsidwa ndi kupakidwa pulasitiki kuti ipange margarine wosinthasintha. Pakadali pano, imagwiritsa ntchito chipangizo chotsekedwa chozimitsira pulasitiki, kuphatikiza chovota kapena chotchedwa scraped surface heat exchanger (unit A), makina ozungulira pin kapena makina okanda (unit C) ndi chubu chopumulira (unit B). Njira yaukadaulo ikuwonetsedwa pa Chithunzi 2:

Zida izi zili ndi makhalidwe awa:

1. Kuthamanga kopanda mpweya kopitilira muyeso

Emulsion yosakanikirana bwino imalowetsedwa mu silinda yozimitsira ndi pampu yothamanga kwambiri ya votator. Kuthamanga kwambiri kumatha kuthana ndi kukana mu chipangizo chonsecho, kuwonjezera pa kugwira ntchito mothamanga kwambiri kungapangitse kuti chinthucho chikhale chopyapyala komanso chosalala. Kugwira ntchito motsekedwa kumatha kuletsa mpweya ndi mpweya chifukwa cha kuzimitsa ndi kuzizira kwa madzi osakanikirana ndi emulsion, kuonetsetsa kuti zinthuzo ndizofunikira paumoyo, komanso kuchepetsa kutayika kwa firiji.

2. Kuzimitsa ndi kusakaniza emulsification

Emulsion imazimitsidwa ndi ammonia kapena Freon mu votator kuti emulsion izizire mwachangu, kotero kuti kupanga tinthu tating'onoting'ono ta kristalo, nthawi zambiri ma microns 1-5, kuti kukoma kukhale kosavuta. Kuphatikiza apo, chokokera chomwe chili pa shaft yozungulira mu votator chimagwirizana kwambiri ndi khoma lamkati la silinda, kotero chokokera chomwe chikugwira ntchito sichimangokanda kristalo nthawi zonse chomwe chimamatira kukhoma lamkati, komanso chimapangitsa emulsion kufalikira kuti ikwaniritse zofunikira za emulsification ya kamvekedwe.

3. Kukanda ndi kuchotsa makulidwe (makina ozungulira pini)

Ngakhale kuti emulsion yoziziritsidwa ndi wovotator yayamba kupanga makristalo, ikufunikabe kukula pakapita nthawi. Ngati emulsion iloledwa kuuma ikapuma, netiweki ya makristalo olimba a lipid imapangidwa. Zotsatira zake n'zakuti emulsion yoziziritsidwayo ipanga misa yolimba kwambiri yopanda plasticity. Chifukwa chake, kuti mupeze zinthu za margarine zokhala ndi plasticity inayake, kapangidwe ka netiweki kayenera kusweka pogwiritsa ntchito makina asanayambe kupanga netiweki yonse, kuti akwaniritse zotsatira zochepetsa kukhuthala. Kukanda ndi kuchotsa makulidwe kumachitika makamaka mu makina ozungulira pin.

Unit A (votator) kwenikweni ndi chipangizo choziziritsira cha scraper. Emulsion imayendetsedwa mu unit A yotsekedwa (votator) ndi pampu yamphamvu kwambiri. Zinthuzo zimadutsa mu ngalande pakati pa silinda yozizira ndi shaft yozungulira, ndipo kutentha kwa zinthuzo kumatsika mofulumira chifukwa cha kuzimitsa kwa choziziritsira. Mizere iwiri ya zoziritsira imayikidwa pamwamba pa shaft. Makristalo opangidwa mkati mwa votator amachotsedwa ndi choziritsira champhamvu kuti nthawi zonse awonetse malo atsopano ozizira ndikusunga kutentha koyenera. Emulsion imatha kufalikira pansi pa ntchito ya choziritsira. Zinthuzo zikadutsa mu unit A (votator), kutentha kumatsika kufika madigiri 10-20, komwe kumakhala kotsika kuposa malo osungunuka a mafuta. Ngakhale mafuta ayamba kuuma, sakhala olimba. Pakadali pano, emulsion imakhala yozizira ndipo ndi madzi okhuthala.

Mzere wozungulira wa unit A (votator) umakhala wopanda kanthu. Pakagwiritsidwa ntchito, madzi otentha a madigiri 50-60 amathiridwa pakati pa mzere wozungulira kuti ateteze kuti makristalo asamamatire ndi kuchiritsidwa pa mzerewo ndikupangitsa kuti atsekeke.

Chigawo C (makina ozungulira pin) ndi chipangizo chokanda ndi kuchotsa makulidwe, monga momwe zasonyezedwera pachithunzi pamwambapa. Mizere iwiri ya maboluti achitsulo yayikidwa pa shaft yozungulira, ndipo mzere wa maboluti achitsulo okhazikika wayikidwa pakhoma lamkati la silinda, omwe amazunguliridwa ndi maboluti achitsulo pa shaft ndipo sakhudzana. Shaft ikazungulira mofulumira kwambiri, maboluti achitsulo pa shaft amadutsa mpata wa maboluti achitsulo okhazikika, ndipo zinthuzo zimakanda kwathunthu. Pogwiritsa ntchito izi, zimatha kulimbikitsa kukula kwa makristalo, kuwononga kapangidwe ka netiweki ya kristalo, kupanga makristalo osapitirira, kuchepetsa kusinthasintha, ndikuwonjezera pulasitiki.

Unit C (makina ozungulira pin) imagwira ntchito yokanda mwamphamvu usiku wozizira kwambiri, kotero imangofunika kusungidwa kutentha ndipo siifunika kuziziritsidwa. Popeza kutentha kwa crystallization kumatulutsidwa (pafupifupi 50KCAL/KG), ndi kutentha komwe kumapangidwa ndi kukangana kwa kneading, kutentha kwa discharge ya unit C (pin rotor macjhine) kumakhala kokwera kuposa kutentha kwa chakudya. Pakadali pano, crystallization imakhala pafupifupi 70%, koma imakhalabe yofewa. Chomaliza chimatulutsidwa kudzera mu valavu yotulutsira, ndipo chidzakhala cholimba pakapita nthawi inayake.

Margarine ikatumizidwa kuchokera ku C unit (makina ozungulira pin), imafunika kutenthedwa pa kutentha kwina. Nthawi zambiri, mankhwalawa amaikidwa pa kutentha kwa madigiri 10 pansi pa kutentha kwa maola opitilira 48. Mankhwalawa amatchedwa kucha. Mankhwala ophikidwawo amatha kutumizidwa mwachindunji ku fakitale yopangira chakudya kuti akagwiritsidwe ntchito.
