ABSTRACT:
In a continuous standardizing and blending system, a liquid (e.g. whole milk) having a known composition is introduced into a separator for separating the milk into components, e.g. a skim (fat-free) component and a high-fat component such as cream. The milk enters the separator through a conduit having a flow meter positioned therein for providing a electrical analog signal corresponding to the flow rate through the conduit. The separator has a skim outlet connected to a skim conduit and a cream outlet connected to a cream conduit. A similar flow meter in the cream conduit generates an output electrical analog signal corresponding to the flow rate through that conduit. A programmed analog control unit compares the signal from the milk flow meter with the signal from the cream flow meter and provides a control signal which regulates the setting of a throttling valve upstream from the cream flow meter. This setting controls the flow rate of cream through the cream conduit. By controlling the ratio between the raw or whole milk flow as it enters the separator and the cream flow as it leaves the separator, the system regulates the fat test of the cream. The skim and a controlled proportion of the cream flow can be recombined downstreaam to form milk products of predetermined fat content, e.g. 1, 2, 3.5%, etc. Various additives can also be blended with the standardized milk product. With this system, one need only know the initial fat content of the raw or whole milk and on-stream fat analysis is not necessary.
