Imveliso yeMajarini yePastry yiTubular Chiller 1

Abstract

Imajarini yepastry kufuneka ibe yiplastiki kwaye izinzile. Ukuhamba kobugcisa bokuvelisa imajarini ye-pastry kunokucwangciswa ngokulula kakhulu nge-tubularchiller (i-tubular ekhutshiweyo yokutshintshisa ubushushu bomhlaba). Ngexesha lokucutshungulwa nzulu kwe-oyile, ukupholisa kunempembelelo enkulu kwi-crystallization ye-pastry margarine. Imajarini eyahlukileyo ifuna inkqubo eyahlukileyo kunye nemeko yokuthambisa.

Amagama angundoqo : imajarini ye-pastry; igubu elipholileyo; i-tubular chiller, i-scraped surface heat exchanger, imveliso yemajarini.

Ukwaziswa kobugcisa be-tubular chiller

Nangona iimveliso ze-margarine ezinqabileyo ziye zaveliswa iminyaka emininzi, abantu baye bazama ukufumana indlela efanelekileyo yeemeko zenkqubo, ngokukodwa kwi-crystallization yefomyula yemveliso eyahlukeneyo phantsi kweemeko ezahlukeneyo zokucubungula. Ngaphambi kokuveliswa kwe-scraper heat exchanger, okanye umatshini wokucima i-tube, zonke iimveliso ze-margarine zaveliswa kusetyenziswa ukucima i-drum kunye noomatshini bokuxova. Ngenxa yomatshini wokucutshungulwa kombhobho uneengenelo ezininzi xa kuthelekiswa nabanye oomatshini bokusetyenzwa, ke ngoku abavelisi bemajarini basebenzisa imveliso yayo yemajarini ethambileyo yepastry, eli phepha kumatshini wokucoca ityhubhu yokucima ukuvelisa inkqubo yemajarini ethambileyo yepastry ukwenza intshayelelo ethile.

Iimpawu eziphambili ze-margarine ezinqabileyo ziyiplastiki kunye nokuzinza. Xa i-margarine igoqwe kwaye iqhutywe ngokuphindaphindiweyo, iileyile kufuneka zihlale zingaphumi kwintlama, ngoko iplastiki ibalulekile; Uzinzo nalo lubalulekile. Ukuba i-margarine ayiqini ngokwaneleyo ukuba ibe yinto ethambileyo okanye i-oil permeable, kwaye ifakwe kwintlama, i-oyile ye-oyile phakathi kweengqimba zentlama iya kuncitshiswa kakhulu.

Ulwakhiwo lomatshini wokucima umgqomo we-rotary lulula, kufuneka kuphela ukulungelelanisa iiparitha ezimbalwa kwimveliso inokuvelisa iimveliso zemajarini ezihlwahlwazayo. I-margarine ye-pastry ene-flaky eveliswa ngumatshini wokucima i-drum ine-plasticity enhle, akulula ukungena kwioli, kwaye izinzile kakhulu kwiqondo lokushisa elikhulu. Umatshini wokucima umbhobho kunomatshini wokucima igubu ekusebenzeni wenze inkqubela enkulu, ebonakaliswa ikakhulu kwi:

(1)Kwimveliso yokulungiswa kwemibhobho etywiniweyo, ukutywinwa okulungileyo, iimeko zococeko nazo ziyakuphucula kakhulu;
(2)Ukuphunyezwa kokusebenza koxinzelelo oluphezulu, olubaluleke kakhulu ekuveliseni imajarini ecocekileyo;
(3) Ukuguquguquka okuhle, kunokutshintsha ngokukhawuleza isantya, uxinzelelo, amandla okukhenkceza kunye nezinye iimeko zokusetyenzwa.

Inkqubo emele ukuveliswa kwemajarini ethambileyo yepastry ngomatshini wokucima ityhubhu yile ilandelayo:
Impompo yeplunger yoxinzelelo oluphezulu ※ Uxinzelelo oluphezulu lwe-tubular olukhuhla umphezulu wokutshintsha ubushushu (Iyunithi A) ※ Iseti yekristali ephakathi ※ Umatshini wokujikeleza wepayina oshukumisayo (Iyunithi B)※ ityhubhu enkulu yomthamo ※ Isilayidi/ukupakishwa kwebhloko.

Umsebenzi we-crystallizer ephakathi ulingana ne-kneader evuselelayo. Itholakala kumbhobho wokucima umatshini wokucubungula kwaye uqhutywe ukujikeleza nge-cutter shaft yomatshini wokucubungula.

Kukulungele ukulungelelanisa ukuhamba kwemveliso ukuvelisa imajarini ye-pastry ene-flaky nge-tube quenching machine. Injongo yokulungelelanisa inkqubo inokufezekiswa ngokuguqula indlela yokudibanisa yombhobho wokudibanisa phakathi kweqela lombhobho wokucima (iyunithi A) kunye neyunithi yokuxova (iyunithi B), ekulula ukuyisebenzisa. Ngokomzekelo, iyunithi yokuxova (iyunithi B) inokufakwa phakathi kombhobho wokucima iyunithi A, ilandela ukuhamba kwe-A 1 ※A 2 ※B1 ※B2 ※A 3 ※A 4, okanye ukutshintsha ukuhamba. ye-A 1 ※A 2 ※A 3 ※A 4 ※B1 ※B2. Ngokutshintsha nje inkqubo yokucubungula kunokuphucula umgangatho wemveliso. Kule nkqubo ingentla, inkqubo yokubeka iyunithi B phakathi kwityhubhu yokucima iyunithi A ifanelekile ngokukodwa kwi-oyile yemifuno esekelwe kwioli yesundu, ebonakaliswe ngamaxesha amaninzi kwimveliso yokuvelisa. Kwaye xa izinto eziphambili zemveliso ziyinkomo, iziphumo ezingcono zinokufumaneka ngokubeka iyunithi B emva kweyunithi A.

Umthamo wokuxova ugqitywe ngokuqulunqwa kwemveliso, umzekelo, umthamo omkhulu wokuxova kufuneka usetyenziswe ekuqulunqweni kweoli kunye ne-crystallization ecothayo. Kwinkqubo yokuvelisa umbhobho wokupholisa ngokukhawuleza, umphumo wokuxova ngumthamo weqela eliphakathi kunye nomthamo wekristallizer kunye nokubetha iyunithi yokuxova (B) isixa somthamo weyunithi, ngoko xa utshintsho kwifomyula yemveliso, kufuneka. ukulungelelanisa umthamo wenkqubo yokuxova, mhlawumbi ngokunyuka kweyunithi ye-B okanye ukuncipha, kunokunyusa okanye ukunciphisa umthamo ophakathi kokungunda, Inokuthi yenziwe ngokudibanisa kunye nokukhupha ngexesha elifanayo, bhetyebhetye kakhulu.
