Abstract:
A device for producing a skim milk starting material milk is disclosed. The device includes a first centrifugal separator that separates milk into a cream fraction and a skim milk fraction, a microfilter that separates the skim milk fraction into a permeate and a retentate, a second centrifugal separator that separates the retentate into a clean fraction and a high bacteria content sludge, and a means for returning the clean fraction to the microfilter. The permeate is provided as the skim milk starting material milk.
Abstract:
Liquid clarifier and method for clarifying liquid, comprising a liquid reactor which comprises an cylindrical tank having an upper vertical section and a lower tapered section, an inner cylinder extending along at least part of the upper section of the tank and an outlet for clarified liquid at the top of the tank, where the liquid clarifier further comprises a gas compressor adapted to inject compressed gas into the lower region of the cylinder and an inlet for an unclear liquid at the upper region of the cylinder, and at least one partition wall inside the cylinder, where the at least one partition wall create flow channels in the lower region of the inner chamber, where the compressed gas is adapted to be injected through gas inlets in flow channel/s in order to create an upward flow in the flow channel/s having gas inlets, which will create a downward flow in the flow channel/s without gas inlets, where the at least one partition wall extends out of the lower region of the cylinder. The advantage of the invention is that different kinds of liquids can be clarified in an efficient and fast way without the need of specific additives.
Abstract:
The disclosure relates to a method of improving the efficiency of fat separation in the separation of a liquid food product with a certain fat content. The method includes the method step that the liquid food product is caused to pass through a first separator where the product is divided up into a lighter and a heavier phase. The first separator is regulated so that the lighter phase will have a fat content which is less than 15%. The method also includes the method step that the lighter phase is caused to pass through a second separator.
Abstract:
A method of operating a separator to disinfect raw milk or whey by operating the separator within a range of an optimal clarifying effect by recirculating a portion of a disinfected milk phase with an entraining liquid.

Abstract:
A separator for disinfecting raw milk or whey. The separator includes a rotatable drum having a vertical axis of rotation. The separator further includes a disk stack, at least two outlets and an inlet. A method is disclosed for operating the separator.
Abstract:
A method of preventing blockages of flow paths of a separator, the separator processing a fat-containing product such as milk. The method steps include determining a concentration of the fat content of an outflowing product phase from the separator to detect an imminent clogging, and shifting a separation zone in a separator drum of the separator for a defined minimum time period by changing operating parameters.
Abstract:
In a milk processing system wherein heat treated milk is initially separated into high-fat and low-fat milk and subsequently reconstituted by adding a selected proportion of high-fat milk to the low-fat milk, control means are provided for automatically controlling the proportion of high-fat milk mixed with the low-fat milk to provide a milk blend of standardized butterfat content which is then homogenized. The control means includes a photoelectric monitoring system for continuously measuring the butterfat content of a sample of the homogenized milk as the latter flows continuously through the processing system under pressure of the homogenizer in the system. The butterfat content measurement is converted to digital signals which are compared to a pre-set digital signal corresponding to a desired butterfat content level to produce a digital corrective signal which controls a digital valve regulating the proportion of high-fat milk blended with the low-fat milk in the processing system. Means are also provided for calibrating the control means at selected intervals to adjust the pre-set digital signal therein to correspond precisely to the desired butterfat content level.
Abstract:
A method and apparatus for regulating the fat content of milk, including that of cream, by separating whole milk into skim milk and cream, mixing part of the cream with the skim milk, determining the respective densities of the skim milk and of the mixture, and controlling the mixture ratio as a function of the difference between these densities by means of an electronic control unit connected to a dosing pump. The fat content of cream may also be regulated by using a pressure control valve, and the fat content of milk intended for cheese production may be regulated in proportion to the nonfat solids content.
