Ukuqengqeleka kwetiibhekisa kwinkqubo apho amagqabi eti aqengqeleka abe yimicu phantsi kwesenzo sokunyanzelwa, kwaye izicubu zeseli yeqabunga zitshatyalalisiwe, okukhokelela ekuphuphumeni okuphakathi kwejusi yeti. Yinkqubo ebalulekileyo yokwakheka kweentlobo ezahlukeneyo zeti kunye nokwakheka kwencasa kunye nephunga. Iqondo lokuqengqeleka lidla ngokulinganiswa “ngomlinganiselo wokonakala kwezicubu zeseli”, “umlinganiselo wokuhluma”, kunye “nomlinganiselo weti eyaphukileyo”. Xa uguqa, kubalulekile ukuhlukanisa phakathi kokutshisa okutshisa kunye nokuqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhaqhayo, kwaye uhlawule ingqalelo kwimpembelelo yexesha kunye noxinzelelo ekuqhubeni ngexesha lokusebenza.

Ukuqengqeleka okushushu kunye nokubanda

Oku kubizwa ngokuba yi-hot rolling ibhekisela ekuqengqeni amagqabi abunileyo ngoxa esashushu, ngaphandle kokuwapholisa; Okubizwa ngokuba yi-cold rolling kubhekisela kwinkqubo yokuguqa amaqabunga aluhlaza emva kokuba ekhutshiwe ebhodweni kwaye avunyelwe ukupholisa ixesha elithile de iqondo lokushisa lamagqabi liyehla kwiqondo lokushisa. Ukuqengqeleka kuvumela imixholo yeeseli zamagqabi (ezifana neeprotheni, i-pectin, isitashi, njl. njl.) ukuba zingene kumphezulu wamagqabi. Ezi ziqulatho zine-viscosity kumxholo othile wokufuma, oluncedo ekuqengqeleni amagqabi eti abe yimicu kunye nokulungisa imilo yawo ngexesha lokumisa. Amagqabi anemigangatho eyahlukeneyo yobudala kunye nokuthamba aneempawu ezahlukeneyo zesebe. Amagqabi anesisa esiphezulu athambekele ekwenzeni imicu xa egqitywe ngenxa yomxholo we-cellulose ephantsi kunye nomxholo ophezulu we-pectin; Amagqabi amadala aqulethe isixa esikhulu sestatshi, kwaye ukuwaqengqa ngelixa eshushu kunenzuzo ukuba isitashi siqhubeke ne-gelatinization kwaye sixube kakuhle kunye nezinye izinto, ngaloo ndlela kwandisa i-viscosity yendawo yamagqabi. Ngelo xesha, phantsi kwesenzo sokushisa, i-cellulose iyathambisa kwaye yenza imicu ngokulula. Kodwa into engalunganga yokuqengqeleka okushushu kukuba umbala wegqabi udla ngokuba tyheli kwaye kukho ukutshona kwamanzi. Ke ngoko, kumagqabi athambileyo, aqhele ukwenza imicu ngexesha lokuqengqeleka. Ukuze kugcinwe umbala omhle kunye nephunga, kufuneka kusetyenziswe ukuqengqeleka okubandayo; Kumagqabi amadala asele ekhulile, ukuwaqengqa ngelixa eshushu kunokufikelela inkangeleko engcono. Nangona ukuqengqeleka okushushu kunempembelelo kumbala kunye nevumba, amagqabi amadala sele enevumba elisezantsi kwaye aluhlaza mnyama. I-Hot rolling ilahlekelwa yi-chlorophyll ethile, engenawo umphumo omncinci kumbala wabo, kodwa ngamanye amaxesha yenza ukuba ngaphantsi kwamagqabi kukhanye. Ke ngoko, amagqabi amadala kufuneka abekwe phantsi kwe-hot rolling. Amagqabi amatsha aqhele ukubonwa anethupha elinye, amagqabi amabini, kunye namagqabi amathathu anoburhabaxa obuphakathi kwaye kufuneka axovulwe ngobunono. Amagqabi aluhlaza kufuneka asasazwe kancinci kwaye axove xa eshushu. Ubuchule bokuqengqeleka okushushu kunye nokubanda kufuneka kuxhomekeke kwimeko ethile.

Ixesha lokuqengqeleka kunye noxinzelelo

Ezi zimbini zihlobene ngokusondeleyo kwaye zifanele ziqwalaselwe kunye, kugxininiswe inkalo enye kuphela akwanelanga. Ngokuqhelekileyo, kukho imeko apho ixesha lokuqengqeleka lingekude, kodwa ngenxa yoxinzelelo olugqithisileyo, iziqu kunye namaqabunga ahlukeneyo, kwaye amaqabunga adibeneyo aphuka ngaphambi kokuba abe yimichilo. Ukuqengqeleka kwamagqabi kufuneka kufezekiseke izinga elithile lokuqhekeka kweeseli ngelixa ugcina ingqibelelo yeentambo, kwaye umlinganiselo womcu kufuneka uhlangabezane neemfuno ezichaziweyo. Amathupha athambileyo kunye nezithole ezitsolo kufuneka zigcinwe kwaye zingaphulwa. Ukongeza kwisixa esifanelekileyo samagqabi, kufuneka kube "ixesha kufuneka liqinisekiswe kwaye uxinzelelo kufuneka lufaneleke". Ukuba uxinzelelo alufanelekanga, ngakumbi ukuba lunzima kakhulu, umphumo wokuqengqeleka uya kuba nzima ukuqinisekiswa. Ngenxa yokuba phantsi koxinzelelo olugqithisileyo, i-buds kunye namaqabunga ngokuqinisekileyo aya kuphuka kwaye aphule emva kwexesha elithile. Nangona ixesha lokuqengqeleka kwamagqabi ahamba phambili libekwe kwimizuzu engama-20-30, ngokuqhelekileyo akucebisi ukuba kusetyenziswe uxinzelelo okanye kusetyenziswe uxinzelelo olulula kuphela; Ukuba olu hlobo lwegqabi elihamba phambili liphantsi koxinzelelo olugqithisileyo, luya kubangela imicu yeti engaphelelanga kunye nezithole ezaphukileyo emva kwemizuzu eyi-15-20 yokuxova. Ke, xa uxova amagqabi ethenda, ixesha kufuneka liqinisekiswe ngaphandle kokufaka uxinzelelo okanye ukusebenzisa uxinzelelo olulula, kwaye ixesha lokuxova alinakuba lifutshane kakhulu. Le yindlela ebalulekileyo yokuqinisekisa ukuba “ifuna ukuxovulwa ngokucokisekileyo, iqhekezwe ngokuqhubekayo ibe yimicu, kwaye igcinwe ibukhali”. Ngokuchasene noko, ukuqengqeleka kwamagqabi amadala kunzima ukuhlangabezana neemfuno zokuqengqeleka ngaphandle kokufaka uxinzelelo olunzima.

Ukuze kuphuculwe ukusebenza kakuhle kunye nokunciphisa ukunyanzeliswa kwabasebenzi, uhlobo lweendibano ezininziiti rollerkwaye ngokuzenzekelayo ngokupheleleyoumgca wokuvelisa itiziye zaphuhliswa, ezinokufikelela ekuvuleni okuzenzekelayo, ukulinganisa kunye nokutya, ukuvala, ukuxinzelela, kunye nokukhupha kuyo yonke inkqubo. Iiparamitha zenkqubo nazo zinokuhlengahlengiswa ukwenza umgangatho wokuqengqeleka ulawuleke ngakumbi. Ngokusebenzisa itekhnoloji yolawulo oluzenzekelayo lwe-PLC kunye nokwamkela indlela yonxibelelaniso yoomatshini abaninzi yokuqengqeleka kunye nokujija, inkqubo eqhubekayo yokwenziwa kwe-automation yokondla koomatshini abaninzi kunye nokusebenza komjikelo wokuqengqeleka kuphunyeziwe. Kodwa olu hlobo lokuqengqeleka kunye neyunithi yokujija lusafuna ukuhamba ngokuvala kunye nokutyisa i-blade, kwaye ifezekisa kuphela ukuqengqeleka okungapheliyo.

IINGCEBISO: Ukuqengqeleka kweti eluhlaza kufuna ukwazi umgaqo wokuqengqeleka kancinci kwamagqabi athambileyo kunye nokuqengqeleka okukhulu kwamagqabi amadala
Ubunzima, ubude, kunye nendlela yokuqengqeleka kunempembelelo enkulu kumgangatho weti eluhlaza. Ukuba kusetyenziswe amandla amaninzi, inani elikhulu lejusi yetiyi liya kuphuphuma, kwaye ezinye i-flavonoids zixutywe ngokulula ukwenza izinto ezimnyama ezimnyama, ezinobungozi kumbala wamaqabunga eti; Kwangaxeshanye, ngenxa yokwanda kwesantya somonakalo weseli, umbala wesobho utyebile kodwa awuqaqambi ngokwaneleyo. Ukuba ixesha lokuxova lide kakhulu, izinto ze-polyphenolic ziyakwazi ukusabela kwi-oxidation kwiqondo lobushushu begumbi, okubangela ukuba umbala wesuphu ujike ube tyheli; Nangona kunjalo, ukungonelanga kwe-rolling kubangela incasa elula kunye nombala, ongenakukwazi ukwenza i-tight and linear shape yeti eluhlaza, ukunciphisa umgangatho wayo wangaphandle. Ke ngoko, iindlela ezahlukeneyo zokuqengqeleka kunye nokujija ngexesha lokucubungula zineempembelelo ezahlukeneyo kumgangatho weti.
