Description

Technical Field

[0001] The present invention belongs to the technical field of separation equipment, and in particular relates to a high-speed modulated milk separator for dairy product processing and a use method thereof. Background Art

[0002] In dairy processing, the purity and uniformity of formula milk play a crucial role in product quality and taste. High-speed separators can effectively remove impurities and cell debris from formula milk, improving product purity. Furthermore, by precisely separating fat, dairy products with varying fat contents can be produced to meet diverse consumer needs. The high-speed separator operates based on centrifugal separation technology. When formula milk enters the separator, the centrifugal force generated by high-speed rotation causes the different densities within the emulsion to separate radially. Specifically, less dense fat globules are pushed toward the axis of rotation, forming cream, which flows downward and is discharged; the denser skim milk flows outward and is discharged through the upper nozzle; while denser mechanical impurities settle on the inner wall of the separator.

[0003] Traditional formula milk centrifuges consist of a rotating drum, a slag discharge mechanism, a drive system (motor, reducer), and a control system. However, the high viscosity of the emulsion leads to poor fluidity, affecting separation efficiency. Furthermore, impurity deposits can clog the filter or hinder slag discharge. The mechanical forces of high-speed agitation and separation can disrupt the fat globules and protein structure in the milk, while also drawing air into the liquid to form tiny bubbles and foam, affecting the taste of the formula milk. Furthermore, the equipment is not airtight and is prone to leakage.

[0004] Chinese invention patent CN216149563U (publication date April 1, 2022) discloses a high-speed modulated milk separator, including a separator body, a main body support frame, an auxiliary support platform, a rotating machine body, a hand buckle slot, and a cross hand support plate. The main body support frame is fixedly installed around the bottom of the separator body, and the auxiliary support platforms are fixedly installed on the left and right sides of the main body support frame. The top of the auxiliary support platform is fixedly installed on the bottom of the separator body. It is equipped with a sealing fixing ring, a soft rubber slot, a sealing soft rubber ring, and a soft rubber ring fixing plate. The above structures are combined to achieve the purpose of sealing the inside of the separator through the soft rubber slot and the sealing soft rubber ring during use, so as to prevent the modulated milk from seeping out from the gap under high-speed rotation. A foam collector is provided at the bottom of the separator body, and the foam collector is used to separate the generated foam from the modulated milk.

[0005] While the above-mentioned prior art solves the separator's sealing problem and achieves foam separation, the foam is composed of fat and protein, and simply separating the foam actually reduces the utilization rate of the formula milk raw materials. Reducing foam production can reduce waste while improving the taste of the formula milk. Furthermore, the cleaning problem of the separator's inner wall remains to be solved. In view of this, the present application provides a high-speed formula milk separator for dairy processing and its use method. Summary of the Invention

[0006] The present invention addresses the problems of foam generation and impurity cleaning on the inner wall of the high-speed separator in the existing technology of dairy product processing, and provides a high-speed modulated milk separator for dairy product processing. The separator can reduce the excessive foam generated during the separation process that affects the fineness of the finished product, achieve the effect of efficient separation, save materials and is easy to operate.

[0007] A high-speed modulated milk separator for dairy product processing comprises a separator body, a driving mechanism, a central shaft, a stirring mechanism, a self-cleaning mechanism and a supporting mechanism.

[0008] The driving mechanism is provided on the top of the separator body, a feed port is provided at the bottom of the separator body, and a discharge port is provided at the top; the upper end of the central shaft is fixedly connected to the motor output end of the driving mechanism, and the lower end of the central shaft is fixedly connected to the stirring mechanism; the self-cleaning mechanism is provided on the upper part of the separator body and below the driving mechanism; the supporting mechanism is provided at the bottom of the separator body;

[0009] The stirring mechanism includes a circular base, multiple stirring rods, and a spherical end. One end of the multiple stirring rods is evenly fixed to the circular base, and the other end spirals down and converges at the end. The stirring mechanism is generally larger in the middle and smaller at both ends.

[0010] The supporting mechanism consists of a circular base and a plurality of supporting frames.

[0011] Preferably, the multiple stirring rods of the stirring mechanism are made of cylindrical stainless steel and are integrally formed with the end;

[0012] The self-cleaning mechanism includes a water tank, a nozzle, and a slag discharge port at the bottom of the separator body, the nozzle spraying high-pressure water along the inner wall of the separator to remove the residue attached to the inner wall of the separator; the slag discharge port is used to discharge the residue and is arranged outside the feed port and below the feed port;

[0013] Furthermore, the direction of the nozzle can be adjusted so as to clean the inner wall and the stirring mechanism in all directions.

[0014] The present invention also provides a method for using a high-speed modulated milk separator for dairy product processing, the specific steps of which are as follows:

[0015] Step S1: feeding: open the feeding valve and inject the prepared milk from the feeding port at the bottom of the separator;

[0016] Step S2: stirring and separating; the driving mechanism is started, and the stirring mechanism rotates at a high speed under the drive of the driving mechanism; the skim milk with a higher density flows outward and upward and is discharged through the discharge port; the fat with a lower density flows outward and downward and is discharged through the slag discharge port; impurities adhere to the inner wall of the machine body due to poor fluidity;

[0017] Step S3: After step S2 is completed, cleaning is performed; the self-cleaning mechanism is started, and the nozzle of the self-cleaning mechanism sprays high-pressure water from the top to clean the inner wall of the separator and the stirring device.

[0018] Compared with the prior art, the technical solution of this application has the following advantages and effects:

[0019] 1. Existing high-speed milk separators generate intense shearing, impact, and friction due to the high-speed rotation of the stirring mechanism, causing the milk protein to produce a large amount of foam. This application optimizes the structure of the separator's stirring mechanism into a streamlined spiral structure, forming a flexible boundary during the stirring process, reducing shear and friction on the milk surface, thereby reducing foam generation, ensuring a smooth taste while saving raw materials.

[0020] 2. Existing high-speed milk separators are prone to clogging the machine body and inlets and outlets, affecting separation efficiency, as the separated residue adheres to the inner wall and the connections of the stirring mechanism are difficult to clean. This optimized stirring mechanism is spiral-shaped, and the integrated connection method reduces gaps that easily harbor dirt and grime. A self-cleaning mechanism is also incorporated, with high-pressure water nozzles installed along the top and around the inner wall of the separator, allowing for rapid discharge of waste through the bottom discharge port, enabling rapid cleaning of the machine body.

[0021] The above is only an overview of the technical solution of the present application. In order to enable the technical means of the present application to be implemented in accordance with the contents of the specification and to make the above-mentioned and other purposes, features and advantages of the present application more clearly understood, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
