Pastry Margarine Ntau Lawm Los Ntawm Tubular Chiller 1

Abstract

Pastry margarine yuav tsum yog yas thiab khov kho.Cov technics ntws ntawm kev ua pastry margarine tuaj yeem npaj tau yooj yim heev los ntawm tubularchiller (tubular scraped nto tshav kub exchanger).Thaum lub sij hawm sib sib zog nqus ntawm cov roj, txias muaj qhov cuam tshuam tseem ceeb ntawm crystallization ntawm pastry margarine.Txawv margarine xav tau cov txheej txheem sib txawv thiab tempering.

Cov lus tseem ceeb: pastry margarine;txias nruas;tubular chiller, scraped nto tshav kub exchanger, margarine ntau lawm.

Technical qhia txog tubular chiller

Txawm hais tias flaky margarine cov khoom tau nyob rau hauv ntau lawm ntau xyoo, cov neeg tau sim los txiav txim seb qhov zoo tshaj plaws txoj kev rau cov txheej txheem tej yam kev mob, feem ntau yog nyob rau crystallization ntawm txawv cov khoom formula nyob rau hauv txawv kev ua hauj lwm tej yam kev mob.Ua ntej qhov kev tsim ntawm scraper heat exchanger, los yog raj quenching tshuab, tag nrho cov khoom margarine tau tsim siv nruas quenching thiab kneading tshuab.Vim tias lub raj quenching ua tshuab muaj ntau yam zoo piv nrog rau lwm lub tshuab ua haujlwm, yog li tam sim no cov tuam txhab lag luam margarine siv nws cov khoom ntawm flaky pastry margarine, daim ntawv no ntawm lub raj quenching tshuab ua cov txheej txheem flaky pastry margarine ua qee qhov kev taw qhia.

Cov khoom tseem ceeb ntawm flaky margarine yog nws cov yas thiab ruaj khov.Thaum lub margarine yog folded thiab dov tawm ntau zaus, cov khaubncaws sab nraud povtseg yuav tsum nyob twj ywm unbroken nyob rau hauv lub khob noom cookie, yog li plasticity yog ib qho tseem ceeb;Kev ruaj ntseg kuj tseem ceeb.Yog hais tias lub margarine tsis ruaj txaus los ua mos los yog roj permeable, thiab yog absorbed rau hauv lub khob noom cookie, cov roj txheej ntawm lub khob noom cookie yuav txo tau heev.

Cov qauv ntawm lub nruas quench tshuab yog qhov yooj yim, tsuas yog yuav tsum tau kho ob peb yam hauv kev tsim khoom tuaj yeem tsim cov khoom lag luam margarine.Lub flaky pastry margarine ua los ntawm lub nruas quench tshuab muaj cov yas zoo, tsis yooj yim rau kev nkag mus rau roj, thiab ruaj khov heev hauv qhov kub thiab txias.Tube quenching tshuab tshaj lub nruas quenching tshuab hauv kev ua tau zoo tau ua tiav ntau dua, uas yog qhov tseem ceeb hauv:

(1) Hauv cov khoom lag luam ntim cov yeeb nkab, kev sib khi zoo, kev huv huv yuav txhim kho ntau yam;
(2) Kev paub txog kev ua haujlwm siab, uas yog qhov tseem ceeb tshwj xeeb rau kev tsim cov margarine crisp;
(3) Kev hloov pauv zoo, tuaj yeem hloov pauv ceev, siab, khov lub zog thiab lwm yam kev ua haujlwm.

Tus neeg sawv cev txheej txheem rau kev tsim cov flaky pastry margarine los ntawm raj quenching tshuab yog raws li nram no:
Kev kub siab plunger twj tso kua mis ※ Kev kub siab tubular scraped nto tshav kub exchanger (Unit A) ※ Intermediate crystallizer teeb ※ Stirring ntoo thuv rotor tshuab (Unit B) ※ Loj muaj peev xwm so tube ※ Slice / block packing.

Qhov kev ua haujlwm ntawm qhov nruab nrab crystallizer yog sib npaug rau qhov sib tw kneader.Nws yog nyob rau ntawm lub quench yeeb nkab ntawm lub tshuab ua thiab tsav mus tig los ntawm lub cutter ncej ntawm lub tshuab ua.

Nws yog qhov yooj yim los kho cov kev khiav dej num ntawm cov khoom los tsim flaky pastry margarine nrog raj quenching tshuab.Lub hom phiaj ntawm kev kho cov txheej txheem tuaj yeem ua tiav los ntawm kev hloov pauv hom kev sib txuas ntawm cov yeeb nkab txuas ntawm quenching yeeb nkab pawg (unit A) thiab kneading unit (unit B), uas yooj yim rau kev khiav lag luam.Piv txwv li, lub tshuab kneading chav tsev (unit B) tuaj yeem muab tso rau hauv nruab nrab ntawm cov yeeb nkab quench ntawm chav tsev A, tom qab qhov ntws ntawm A 1 ※A 2 ※ B1 ※ B2 ※ A 3 ※ A 4, lossis hloov mus rau qhov ntws. ntawm A 1 ※ A 2 ※ A 3 ※ A 4 ※ B1 ※ B2.Los ntawm kev hloov cov txheej txheem ua tau yooj yim tuaj yeem txhim kho cov khoom zoo.Nyob rau hauv cov txheej txheem saum toj no, cov txheej txheem ntawm kev muab chav tsev B nyob rau hauv nruab nrab ntawm lub quench raj ntawm chav tsev A yog tshwj xeeb tshaj yog haum rau cov zaub roj formulation raws li xibtes roj, uas tau raug pov thawj ntau zaus nyob rau hauv ntau lawm xyaum.Thiab thaum cov khoom tseem ceeb ntawm cov khoom yog nyuj, cov txiaj ntsig zoo tuaj yeem tau txais los ntawm kev tso chav B tom qab chav A.

Lub peev xwm kneading yog txiav txim siab los ntawm kev tsim cov khoom, piv txwv li, lub peev xwm kneading loj yuav tsum tau siv rau cov roj formulation nrog qeeb crystallization.Nyob rau hauv cov txheej txheem kev ua kom txias txias sai, cov nyhuv kneading yog lub peev xwm ntawm cov pab pawg nruab nrab thiab lub peev xwm ntawm cov crystallizer thiab nplawm lub kneading chav tsev (B) qhov sib npaug ntawm lub peev xwm ntawm chav tsev, yog li thaum muaj kev hloov pauv hauv cov khoom siv mis, xav tau. los kho lub peev xwm ntawm cov txheej txheem kneading, los ntawm B chav tsev muaj peev xwm nce lossis txo qis, tuaj yeem nce lossis txo qis hauv nruab nrab pwm muaj peev xwm, Nws tuaj yeem ua tiav los ntawm kev ntxiv thiab rho tawm tib lub sijhawm, hloov tau yooj yim.
