In U.S. patent 3946113 described a system of continuous normalization and mixing, in which whole milk with a known composition, is introduced into the separator for the separation of milk components such as fat-free component and a component with a high content of fat, such as cream. The milk enters the separator through a pipeline having a flow meter mounted therein for supplying electrical analog signal corresponding to the fluid flow passing through the pipeline. The separator has an outlet for the non-fat component which is connected to the pipeline for the non-fat component, and an outlet opening for cream, United with the pipeline for cream. A similar flow meter in the pipeline for cream produces output electrical analog signal corresponding to the fluid flow passing through the pipelines is the intention of consumption of milk, the signal from the flow meter designed for measuring the flow rate of cream, and produces a control signal that provides a regulation setting a throttling valve located at the front of the meter to cream on the flow direction. This adjustment provides the ability to control the flow of cream through the pipeline for cream. By adjusting the ratio of flow of raw or whole milk when it enters the separator and flow of cream is used for the separator system regulates the fat content in the cream. Skim milk and adjustable part of the flow of cream can be combined in located further along the reservoir with a constant level for the formation of a dairy product with a specified fat content, which is then pumped from the tank through a part of the system in which the mixing. Various additives can also be mixed with normalized dairy product. It is argued that by using this system you only need to know the original fat cheese or whole milk, and there is no need for analysis of fat content in the fluid flow.

In accordance with U.S. patent 3983257 moth skim milk and cream, and the density of the cream is maintained essentially constant by continuous measurement of the density and use of these density measurements for regulation of one of the individual streams.

Thanks to the present invention can be produced dairy product, which is essentially constant given ratio of components, more economical, as the cost of the necessary equipment can be minimized.

For a more complete and clear description of the invention reference is made to the accompanying drawings, given by way of example, in which:

Fig.1 is a schematic view of a device for production of a dairy product of two components;

Fig.2 is a schematic view of the breast installation, comprising the device according to Fig.1;

Fig.3 is a schematic Nisha least four components.

In Fig.1 shows the tank as the tank 1 filler, for example forming-filling-sealing machine packaging, container 1 is a blending tank, connected directly with reciprocating filling machine. The corresponding components of the milk product is continuously fed to the pipes 2A and 2B. Components can represent whole milk and separated milk for the formation of these consumer milk. The pipes 2A and 2B contain the appropriate flow meters 3A and 3B and placed them on the go trends respective valves 4A and 4C for flow control (i.e. valves that are not on-off valves, as are the valves for regulating the continuous flow) driven by respective motors 5A and 5B. In the pipes 2A and 2B along the following control valves 4A and 4B are respective check valves 6A and 6B. The pipes 2A and 2B are connected in place of the 7 compounds, where the two components begin to mix, and a common duct 8 passes to the mixing device 9 and thence into the container 1. Preferably the device is not Sogno is a static mixer (turbulator), preferably made in the form of sheet metal, which is attached to this form, which enables the creation of turbulence in the product passing through the device. The sensor 10 determines the level of product in the tank 1 and transmits this information via the electric circuit 11 to the Central unit 12 controls with panel 12control and contain the necessary software and hardware for automatic control of the motors 5A and 5B. Similarly, information related to the velocity components by flow meters 3A and 3B, is transmitted to the Central unit 12 to control the respective circuits 13A and 13B, while the Central device control 12 is connected to the motors 5A and 5B, respectively, with electrical circuits 14A and 14B.

When using the device according to Fig.1 set the product level in the tank 1, and the volume ratio between the two components are set with panel 12management. The system has two control circuit, correlated with each other as “master - slave”. The main circuit includes a sensor level 10, Central ustroystvo device 12 control and another control valve 4. The flow through a valve 4 serves primarily to maintain a constant level in the tank 1, while the other valve 4 provides for the maintenance of a constant ratio of the two components. When the Central device control 12 generates signals of impending change product, i.e. rapid replacement of milk for milk with different fat content, the sensor 10 level provides the possibility to downgrade the product level in the tank 1 to the extent feasible, to minimize loss of product.

In the installation for production of a milk product according to Fig.2 filling machine indicated by the position 20, the supply tank 1 is connected with its reciprocating fillers 22, intended for filling cartons With open top, shown under the filler 22. Raw, whole milk is fed via the inlet channels 24A and 24 in the respective devices 26A and 26C, where pasteurized whole milk is fed respectively to the separator 28 and the homogenizer 30. From the separator 28 extra cream out through the outlet 32, while the separated milk passes through the exhaust pipe 34 into the pipe 2A and cloaca passes into the pipe 2B and the valve 4B and optionally a buffer tank 36V, mounted on the pipe 2B. In that case, if the buffer tanks 36A and 36V are provided, they can provide continuous flow through the valves 4A and 4B and, therefore, a continuous supply in the machine 20, even during maintenance or minor repair of any of the elements 26, 28 and 30 and provide the possibility of continuous operation of the elements 26, 28 and 30 even in the case when it comes to maintenance or adjustment of the machine 20. In practice, buffer tanks 36A and 36V are used to supply more than one such machine.

There is a possibility of mixing more than two components in a predetermined volumetric ratio while maintaining the amount of the mixed product in the tank 1 is essentially at a constant level. In Fig.3 shows a device in which the mixing takes place at least four components. In this unit, the pipes 2, flow 3, control valves 4, engine 5, the check valves 6 and the electrical circuits 13 and 14 simply duplicated and marked accordingly positions 102A and B, 103A and V, A and B, 105A and V, A and V and A, B, A and B. Pipes 102A and B connected in place 107, which passes General is or more additional devices, consisting of a flow meter/regulating valve and engine/valve, may be positioned to pipeline 108 in the flow direction and attached.

In this embodiment, the main control circuit also includes a sensor 10level, the Central device 12 and control one of the control valves 4 and 104, and there are three subordinate circuit, each of which includes a flow meter 3 or 103, which is connected with one control valve, and which also include the appropriate flowmeter 3 and 103 connected to the respective other control valves 4 and 104. Each of the three subordinate circuits also includes a Central device control 12 and one control valve 4 or 104. Three slave circuit further includes respective other three regulating valve 4 and 104. And in this case, using the panel 12control enter the data for a given level of product P in the container 1, and set the volume ratio of the four components.

It should be noted that between the device 7-9 for mixing and storage tanks 1 and thereby cardboard boxes With no installations the La mix will be located so close to located in the course followed by the supply tank 1, as you design. Thus, it is possible to minimize product loss during the transition from one type of consumer of milk in the other. The advantage of the device for mixing before spending capacity 1 in the flow direction is that even though the container 1 has a very small volume (about 45 liters) compared to the buffer reservoir 36A or 36V (thousands of liters), this capacity enables reliable filling each cardboard box With a preset volume of consumer milk with a specified fat content when using relatively simple and low-cost labor and management system. The use of control valves such as the valves 4A and 4B) instead of dosing pumps provides for the filing of components at a relatively higher cost of components and a relatively higher speed and shorter response time (hence provide a more accurate filling).
