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:
The device has one valve body that can be set at a constant minimum cross-section and another valve body that is not activated until the pressure in a supply connection becomes too high. The valve bodies are accommodated in separate and parallel-streamed valve housings. Since the design allows free selection of the cross-section in the valve housings, extremely wide fluctuations in the concentration of cream can be mastered in accordance with controls technology by means of the second valve body.
Abstract:
A process for separation of raw milk by centrifugal separation into cream, which is cooled in a first heat exchanger, and into skim milk which is heated to pasteurization and cooled by regenerative heat exchange in a second heat exchanger, is described. The characteristic feature is that the feed of raw milk is separated into two part streams, of which the first is heated in the second heat exchanger to separation temperature, while the second part stream is heated in the first heat exchanger and is then combined with the first part stream and centrifugally separated.
Abstract:
An improvement in the method and apparatus for obtaining the specific fat content of milk wherein whole milk and skimmed milk are mixed together as they flow, and the amount of skimmed milk is added according to the previously determined fat content of the whole milk, the fluid quantities of the whole milk and skimmed milk being continuously measured. The method and apparatus are improved by continuously taking samples of the whole milk and continuously determining their fat content, and in between taking the samples and the admixture of the skimmed milk while the whole milk is retained in its supply line for the period of time between the taking and/or evaluation of the particular sample and the controlling of the skimmed milk admixture.
Abstract:
A continuous on-stream milk standardizing and blending system. Whole milk having a known fat content is introduced into a centrifugal separator for separating the milk into its skim and cream components; the milk entering the separator through a conduit having a flow meter positioned therein for providing a digital output signal corresponding to the flow rate therethrough. A digital control unit compares the input signal from the milk flow meter with an input signal received from a similar flow meter positioned in the cream conduit downstream from an air-operated throttling valve; the control unit providing a control signal which regulates the setting of the throttling valve. This setting controls the flow rate of cream through the cream conduit and, thus, establishes the fat test of the cream based on the known fat test of the whole milk. A portion of the cream is then recombined with the skim component in an amount controlled by the digital control unit so as to provide a standardized milk product of the desired fat content (e.g. 3.5% milk). Various additional additives (e.g. condensed skim milk) can also be blended with the standardized milk product.
Abstract:
A method for discharge control of a separator comprises an inlet for a dairy product, a first outlet conduit for a first processed dairy product, and a second outlet conduit for a second dairy product. The first processed dairy product having a higher fat concentration than the second processed dairy product. The method involves detecting a flow rate of the first processed dairy product in the first outlet conduit, controlling the flow rate of the first processed dairy product in the first outlet conduit by regulating an opening degree of a regulating valve connected to the first outlet conduit, detecting the opening degree of the regulating valve, and discharging the separator when the opening degree of the regulating valve exceeds a predetermined value. The invention also relates to a separator for separating a dairy product into a first processed dairy product and a second processed dairy product.
Abstract:
A method of improving the efficiency of fat separation in the separation of a liquid food product with a certain fat content. The method comprises the liquid food product is caused to pass two separators connected in parallel, a first and a second, in which 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 lighter phase from the first of the separators connected in parallel is led into the inlet conduit to the second of the separators connected in parallel.
Abstract:
A system, processes, and milk-based food products made from the system and processes, in which cream is separated from milk to produce an ultra-low fat milk product. The milk product is microfiltered to produce a retentate that is ready to drink and is high in protein and has no or substantially no fat. The permeate from the microfiltration process is ultrafiltered to produce a retentate that is high in protein with few other solids. The permeate may be used to provide protein fortification to other food and beverage products, and is especially useful in its liquid form for such fortification.
Abstract:
A process and system for controlling fat content in standardized milk and standardized cream. Whole milk is separated in a centrifuge into high-fat cream and low-fat milk. The high-fat cream leaving the centrifuge and the non-fat milk leaving the centrifuge are controlled to maintain the compositions of each constant. A portion of the high-fat cream is added to a portion of the non-fat milk to produce standardized milk and a portion of the non-fat milk is added to a portion of the high-fat cream to produce standardized cream. The fat content of the standardized cream is regulated by controlling the amount of the non-fat milk added to the high-fat cream.
