Eksempler på nye udviklinger
• Kontinuerlig anlægsdrift (24/7)
• Avanceret overvågning af anlæg
• Anvendelse af model baseret proceskontrol
• Anvendelse af PAT teknologier
• Komponent udvikling (opskalering)
13

24/7 operation giver mange fordele
• Reduktion af antal start-stop (pulver out of spec. / stand-by energiforbrug)
• 1 start-stop hver 10-14 dage – interval mellem CIP forlænges
• Påvirkning af inddamper og fødesystem skift
• Flere skift – mindre påvirkning ved større anlæg 100% -> 25%
• Optimale skift af inddampere og varmebehandlingssystem – lavere indhold af
termofile bakterier
• Tørrekammer pulverafsætninger reduceres
• Reduktion af farve påvirking af produktet
• Reduktion af uopløselige partikler i produktet
Operatørernes fokus
• Ikke længere start-stop, men optimering af anlæg og produktkvalitet

Milk Processing Trends in Europe
The ”white wave” in EU, as a result of the quota abolition drives investments in
large processing facilities for high quality milk powder and Formulated
Nutritionals.
Focus are powders (milk / various ingredients and nutritionals) all intended for
growing populations with buying power in Asia/ME and Africa
This includes large investments in green field milk / nutritionals powder plants
(7-15 t/h range) and bolt on capacity to existing sites.
GEA delivers a quantum leap to EU dairies
In product quality, througput and efficiency (OEE)
