Abstract:
A device for separating dense particles contained in blood or one or more proteins contained in blood plasma by utilizing a separating arrangement. The separation arrangement includes a feed duct, at least two discharge ducts, a pump for producing a pressure in order to introduce the blood or blood plasma into the separating device, a measuring device provided with the discharge ducts, and a control arrangement connected to the measuring device. The separation arrangement also includes a respective arrangement changing the cross section of at least one of the two discharge ducts and connected to the control arrangement.
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.
Abstract:
A separator for separating raw milk into a skimmed milk phase, a cream phase and an ejection phase that comprises solid impurities is disclosed. The separator includes an ejection port arranged at a periphery of the separator to eject the ejection phase. A cyclone is connected to the ejection port to receive and decelerate the ejection phase, and a vessel in fluid communication with an ejection phase outlet of the cyclone to receive and collect the ejection phase from the cyclone. The cyclone includes a port that is open to the atmosphere, such that pressure build-up created in the cyclone when the ejection phase is ejected from the separator into the cyclone is released.
Abstract:
There is also provided a method of producing a natural cheese having improved melt characteristics from a quantity of raw milk. The method includes separating the raw milk into a cream portion and a reduced fat milk portion. A portion of the cream portion is emulsified in a machine with a mild homogenate process producing reduced size fat globules. All of the cream portion and the reduced fat milk portion is combined into a cheese fluid and pasteurized. A coagulating agent is added to the cheese fluid and processed to produce a natural cheese having improved melt characteristics from the cheese fluid including the emulsified cream portion.
