摘要:
A device for producing a cheese 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 info 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 cream fraction and the permeate are combined to obtain the cheese starting material milk.

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.

The present disclosure includes a method of controlling a centrifuge for the centrifugal production of a milk product. The steps include taking a milk sample at an outlet of the centrifuge from a liquid phase, adding a substance to the milk sample that increases light transmittance of the milk sample, determining the light transmittance of the milk sample by transilluminating the milk sample using a light source and measuring light intensity via a photo cell, determining the fat content from a measurement of the light transmittance, and controlling the centrifuge as a function of the determination of the fat content. The present disclosure also includes a system for controlling the centrifuge.

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.
摘要:
The aim of the invention is to provide a method for the skimming of whey, resulting in better whey cream fat quality and allowing for automatic regulation of the concentration of whey cream. Raw whey is fed into a skimming separator and broken down into a skimmed whey phase and a whey cream phase. Whey cream is discharged through a discharge line and a part thereof corresponding to 0.5-2% of the volumetric flow of the raw whey that is fed into the skimming separator is returned to the feed line of the skimming separator by means of a recirculating device. A density transmitter can be arranged in the recirculating device so that density measurements can be carried out. The density values are transmitted to an evaluation device, enabling regulation of a control valve which is placed in the whey cream discharge line. The method and device for implementing the method are used in the processing of whey which is produced during the production of cheese after the cheese has been separated from the fat during the coagulation of the milk.
