Chifukwa cha kusunga zakudya zabwino komanso kusungirako bwino komanso mayendedwe, shrimp yowuma ndi chinthu chodziwika bwino cham'madzi kuchokera ku Southeast-Asia ndipo chimagulitsidwa kwambiri ku China, Japan, South Korea, Europe ndi North America kuti tipeze zokhwasula-khwasula za m'nyanja, zosakaniza za supu zowumitsidwa ndi zakudya zophikidwa kale. Komabe, chifukwa chokhala ndi mapuloteni ambiri am'madzi am'madzi, shrimp imakhala ndi kulekerera kochepa. Mapurosesa ambiri amakumana ndi zolakwika zomwe zimaphatikizira kuchepa kwa voliyumu, mawonekedwe olimba a nyama, kuchepa kwa madzi m'thupi komanso kuchulukana kwamadzi. Kuti mupeze shrimp yowuma kwambiri yowuma ndi ntchito yabwino yobwezeretsa madzi m'thupi, kuwongolera mosamalitsa kuyenera kuyendetsedwa kudzera mukukonzekera, kuzizira, kuzizira, ndi kuyanika kwa desorption.
Kukonzekera koyambirira kumayala maziko a khalidwe. Shrimp yaiwisi iyenera kutsukidwa, kuchotsedwa ndikutsuka bwino. Kukonzekera kwa enzyme ndikofunikira kwambiri. Kutentha kwa madzi ndi nthawi yonyowa ziyenera kuyendetsedwa mosamalitsa. Kusakwanira kwa blanching kumasiya mapuloteni-ma enzyme akugwira ntchito ndipo kumabweretsa kuwonongeka kwakanthawi pakusungidwa; Kuchuluka kwa blanching kumayambitsa kuchepa kwa mapuloteni komanso nyama yolimba yolimba. Pambuyo pa blanching, kuziziritsa mwachangu ndi kukhetsa kwathunthu kwa madzi opanda madzi kumafunika. Madzi ochulukirapo aulere - amakulitsa nthawi yowumitsa ndikuyambitsa kuzizira pakati pa shrimp. Sakanizani shrimp mumsewu umodzi pa trays ndipo pewani kutukuka kwambiri ndi kufinya.
Kuziziritsa kusanakhale: Kuzizira kozama kwambiri kumafunika kuti shrimp ikhale ndi mapuloteni ambiri. Kusazizira kokwanira kusanakhale kozizira kapena nthawi yogwira kumasiya gawo lina lamadzi lamkati kukhala losazizira. Kusungunuka pang'ono kumachitika pansi pa vacuum ya sublimation ndipo kumabweretsa kuchepa kwakukulu ndi mawonekedwe olimba. Nthawi yogwira isanazindike iyenera kusiyanasiyana malinga ndi kukula kwa shrimp; Nsomba zazikuluzikulu zimafunikira nthawi yotalikirapo kuti zitsimikizire kuzizira kwathunthu pa shrimp core.
Pa kuyanika sublimation, mosamalitsa kulamulira alumali Kutentha kugunda ndi kupewa mofulumira kutentha kukwera. Kutentha kwamphamvu kumayambitsa kusinthika kwa mapuloteni komanso mawonekedwe oyipa. Sungani vacuum yokhazikika popanda kusintha pafupipafupi kuti mupewe kuwonongeka kwa zinthu. Ayezi adzatsika ndi kuthawa pang'onopang'ono m'malo mwa kuphulika kwa nthunzi.
Mu gawo la desorption-drying, madzi omangika amachepetsedwa kukhala mulingo woyenera wotsalira-chinyontho. Chinyezi chotsalira chochuluka kwambiri chimachititsa kuti chinyonthocho chiyamwe komanso kuwonongeka paulendo wautali wapanyanja komanso kusungirako kutentha kwambiri ndipo kumachepetsa moyo wa alumali. Komabe, kuyanika kwa nthawi yayitali kwambiri kumawonjezera kuchepa kwa nyama. Chinyontho chakumapeto chidzakhazikitsidwa molingana ndi nthawi yomwe ikuyembekezeka.
Kupatula apo, shrimp yoyambira ndi makulidwe osiyanasiyana sangathe kugawana njira imodzi yokhazikika. Mafakitole adzamanga malo osungiramo zinthu zakale omwe amagwiritsidwa ntchito kawirikawiri. Mukamaliza, malizitsani zotsekera zodzaza ndi nayitrogeni mwachangu momwe mungathere kuti mulekanitse mpweya ndi chinyezi ndikutsimikizira kuti zinthu zili bwino pakadutsa malire a nyanja.
