Cov Khoom Tswj Khoom:
Cov chaw cia tau khaws cia rau hauv qhov zoo thiab ntawm qhov haum loj. Cov khoom siv tau khaws cia nyob rau hauv qhov tsim nyog nyob rau hauv traceable qhov chaw nrog daim paib kom zoo.
Txias Warehouse Kub Tswj
Qhov kub nyob rau hauv lub warehouse txias yog tswj nyob rau hauv t 2 ~ 8 ° C, thiab saib xyuas kev soj ntsuam system (EMS) uas yog siv tau. Yog tias qhov ntsuas kub tsis pub tshaj, lub kaw lus yuav xa cov tswb rau cov neeg saib xyuas cov khoom siv. Thaum lub tswb txhom, tus neeg teb xov tooj rau lub tsev rau lub tsev rau khoom yuav txav cov khoom lag luam thiab cov khoom siv rau lwm lub tsev muag khoom txias dua. Meanwhile, cov txheej txheem sib txawv yuav raug teeb meem rau kev tshawb nrhiav thiab ntsuas kev ntsuas. Qhov kub hloov tau luam tawm rau cov hneev taw txhua hli
Tuaj Tswj Khoom Siv
Muaj cov txheej txheem sau xov xwm muaj rau kev tau txais daim ntawv tau txais, cim, cais tawm, chaw cia khoom, kev kuaj, kev pom zoo thiab tsis lees paub cov ntaub ntawv. Thaum cov khoom tuaj txog, cov khoom lag luam yuav ua ntej cov ntaub ntawv ntawm lub pob, ntau ntawm cov ntaub ntawv uas tiv thaiv cov chaw muag khoom, cov ntawv xa khoom thiab cov khoom xa tuaj yeem.
