CREAM SEPARATOR
Mora Marco milk separators of the open type series are specially designed to skim, standardize and clarify milk, cream and whey. These separators are studied and manufactured to permit very high rotation speed of the bowl and to obtain the best separation efficiency of solid/heavy parts with very small diameters (fat, dirty, spore and bacteria, etc.). Product feeding comes under pressure by a soft inflow system and is accelerated to separation speed without damaging the fat globules.
This is a very important feature for the treatment of cow’s goat’s milk or sheep’s milk. The wide working surface, the high centrifugal force and the expulsion extremely fast sludge guarantee a great efficiency of separation and cleaning. No recovery pumps are necessary because the skimmed product and the cream exit under pressure.
Cream separator with maintenance tools and spare parts
– Capacity: 1000L/H
– Make/Brand: Mora Marco
– Model/Type: Open Type
– Country of origin: Italy
– Oil level sight glass blasted for transmission
