Skim milk is what remains after cream is removed from raw milk. Cream is removed to bring the fat content of the skim milk as close as possible to the lower limit of a designated range. For this purpose, control of the fat content in the cream and the skim milk is essential. The fat content in the cream and the milk has a direct relationship to their density and is controlled by the measurement thereof. The DM8 vibration liquid density meter has high sensitivity and stability, and a sanitary detector is available upon request. The DM8 enables highly accurate control and is easy to maintain.
In a cream separator the raw milk is separated into lighter cream and heavier skim milk. After passing through sterilization and cleaning processes, the cream is used to make butter and other dairy products, while the skim milk is dried to produce skim milk powder, which is widely used in confectioneries and other foods.
The fat content in the skim milk is controlled by adjusting the flow of the cream at the separator outlet. Liquid density meters are installed at two locations: one in the cream line and another in the skim milk line. The opening of the cream flow regulating valve is controlled according to the measured density values.

Other applications
In addition to milk processing, liquid density meters are well suited for applications such as ice cream manufacturing overrun control.
The DM8 liquid density analyzer measures liquid density of general process liquids with high sensitivity and excellent stability. It has a measuring density range of 0 to 2.0 g/cm3, and unaffected by flow rate and viscosity. Besides general-purpose sensor, sanitary and explosionproof sensor are also available.
