Tempereja bilong kondensa na mak bilong wara
Kondensa em i wanpela bikpela samting bilong wanpela 'freeze dryer', long wanem, tempereja bilong en i save mekim wok bilong 'sublimation' na 'drying effect'. Planti taim, sapos tempereja bilong kondensa i go daun, strong bilong en long holim wara steam, na dispela i mekim na prodak i drai hariap na i gat gutpela kwaliti bilong prodak.
Dispela 'vacuum freeze dryer' i yusim wanpela 'external cold trap' disain. Dispela i no inap long mekim wok bilong rausim wara long ol ikwipmen tasol em i save rausim gut ol samting we kol trap inap kamapim long ol samting i ais pinis, na long dispela rot em i mekim ol samting i kamap ais i kamap wankain na i gat gutpela kwaliti na tu i mekim wok bilong ais-draim i go hariap na i no yusim planti pawa.
Vacuum Degree
Digri bilong 'vacuum' em i wanpela mak bilong presa bilong ges insait long 'freeze-drying envairomen, we i save afektim stret 'rate' bilong wara 'sublimation' na 'uniformity' bilong 'drying'. Ol hai-kwaliti fris draia i save holim wanpela hai vekim digri bilong 10^-3 Pa i go inap 10^-4 Pa, na dispela i mekim na ol i rausim wara hariap na wankain long sempel. Folem wanpela stadi long 'freeze-draim ol redi-long-kaikai sis, olgeta oda bilong mak bilong inkris long 'vacuum degree' inap long daunim taim bilong draim long samting olsem 30%, na tu, dispela inap long mekim gutpela moa long 'rehydration properties' na teis bilong prodak.
Refrigeration System na Hiting Method
Gutpela na strong bilong 'refrigeration system' i save makim stret hamas eneji i yusim na gutpela wok bilong 'freeze-drying process. Nau yet, ol 'freeze dryers' we i yusim ol 'ennvironment friendly refrigerants' na tupela-stej o 'cascade' 'refrigeration systems' em ol i save laikim moa, long wanem, ol i no save yusim gut pawa na tu ol i ken senis long bikpela tempereja. Long sait bilong ol rot bilong hatim, 'radiation heating', 'contact heating', na 'induction heating' i gat ol gutpela na nogut bilong ol; ol kampani i mas makim gutpela rot bilong hatim haus bihainim ol pasin bilong ol samting.
Kontrol Sistem na Otomesen Level
Ol 'freeze dryers' bilong nau i save gat ol gutpela kontrol sistem, olsem PID kontrol na SCADA sistem, long kisim stretpela kontrol na 'real-monitoring bilong ol samting olsem tempereja na 'vacuum', na mekim wok i kamap gen. Ol 'freeze dryer' we i gat planti masin i ken mekim ol wok olsem 'program presetting', 'fault alarm', na 'data logging', na dispela i mekim wok bilong prodaksen na menesmen i kamap gutpela moa.
Olsem wanpela ki pis bilong teknoloji ikwipmen insait long hai-tek fil, seleksen bilong ol pefomens paramita bilong ol 'vacuum freeze dryers' i save afektim stret kwaliti bilong prodak na prodaksen efisiensi. Taim ol i kisim gutpela save long ol bikpela samting olsem 'condenser temperature', 'vacuum level', 'refrigeration system', na 'control system', na bungim dispela wantaim ol eksampel bilong yusim, ol kampani i ken stretim ol nid bilong ol yet na stretim ol hevi bilong indastri long makim ol 'vacuum freeze dryers'.
