Dab tsi yog cov txheej txheem ntawm cov hmoov txhuv nplej siab cassava?

Kev tsim cov hmoov txhuv nplej siab muaj cov txheej txheem los tshem cov hmoov txhuv nplej siab los ntawm cov hauv paus cassava. Ntawm no yog cov ncauj lus kom ntxaws txog covcassava starch txheej txheem kab:

Harvesting thiab Peeling:

Harvesting: Mature cassava cag yog sau los ntawm teb.

Peeling: Cov hauv paus qoob loo raug ntxuav kom tshem tawm cov av thiab cov khib nyiab, thiab tom qab ntawd tev kom tshem tawm cov tawv nqaij. Peeling yuav ua tau manually los yog mechanically, siv lub tshuab peeling.

Sib tsoo:

Kev Sib Tsoo: Cov noob qos yaj ywm peeled yog muab tso rau hauv ib lub pulp. Qhov no tuaj yeem ua tiav siv rauj mills lossis disc mills. Cov txheej txheem sib tsoo ua rau cov phab ntsa ntawm tes ntawm cov qos yaj ywm hauv paus, tso cov hmoov txhuv nplej siab granules.

Rinsing thiab Sieving:

Rinsing: Lub hauv av cassava pulp yog tov nrog dej los ua ib tug slurry. Cov slurry no ces yaug kom tshem tawm fiber ntau thiab lwm yam impurities.

Sieving: Lub slurry yog dhau los ntawm ib tug series ntawm sieves cais cov hmoov txhuv nplej siab granules los ntawm fiber ntau thiab lwm yam khoom hais.

Sedimentation:

Kev daws teeb meem: Cov hmoov txhuv nplej siab nplua nuj slurry raug tso cai nyob rau hauv cov dej xau. Cov hmoov txhuv nplej siab hnyav dua nyob rau hauv qab, thaum cov khoom siv fiber ntau tseem raug tshem tawm hauv dej.

Decantation: Cov kua ntshiab, hu ua supernatant, yog decanted los ntawm cov hmoov txhuv nplej siab.

Dewatering:

Centrifugation: Cov concentrated starch slurry yog ntxiv dewatered siv centrifuges. Qhov no tshem tawm cov dej ntau dhau thiab ua rau lub ncuav mog qab zib moist.

Qhuav: Lub ncuav mog qab zib moist yog qhuav kom txo cov dej noo. Qhov no tuaj yeem ua tiav siv ntau txoj kev ziab khaub ncaws, xws li lub hnub ziab, qhov cub kom qhuav, lossis tshuaj tsuag kom qhuav.

Milling thiab Sifting:

Milling: Cov hmoov nplej qhuav yog milled kom tau cov hmoov zoo.

Sifting: Lub milled starch yog sifted kom tshem tawm tej coarse hais thiab impurities.

Ntim:

Ntim: Cov hmoov txhuv nplej siab ua kom zoo yog ntim rau hauv ntau qhov ntau thiab tsawg, xws li hnab lossis ntim ntim ntau, rau kev faib thiab muag.

Yam tseem ceeb cuam tshuam rau Cassava Starch Zoo:

Cassava Ntau Yam: Ntau yam ntawm cassava siv tuaj yeem cuam tshuam rau cov hmoov txhuv nplej siab thiab zoo.

Lub sij hawm sau qoob loo: Kev sau qoob loo raws sij hawm tuaj yeem ua kom pom cov hmoov txhuv nplej siab thiab zoo.

Cov Txheej Txheem Ua Haujlwm: Cov yam ntxwv zoo li kev sib tsoo kub, pH, thiab ziab ziab tuaj yeem cuam tshuam cov khoom kawg.

Kev Kho Cov Khoom Siv: Kev saib xyuas cov cuab yeej ua haujlwm kom zoo yog qhov tseem ceeb rau kev tsim khoom zoo thiab zoo.

Los ntawm kev ua tib zoo tswj cov xwm txheej no, nws muaj peev xwm tsim tau cov hmoov txhuv nplej siab zoo uas ua tau raws li qhov xav tau ntawm ntau yam kev lag luam.
