Abstract
Description
Technical Field
[0001] This application relates to the field of food preparation technology, and in particular to a processing equipment for dairy meat products. Background Technology
[0002] The creation of alternative meat-like foods, using modern food processing technologies to simulate the texture, flavor, and nutrition of animal meat, is an important research direction in food engineering. Existing meat-like foods are mainly plant-based imitations. However, these plant-based imitations lack some essential amino acids and suffer from insufficient fiber fineness and low sensory realism. The fiber structure produced by existing plant-based imitation processes is typically coarse, showing a significant difference from the fine layering of animal muscle, resulting in insufficient elasticity and chewiness.
[0003] Compared to traditional plant-based meat substitutes, dairy-based meat substitutes offer a richer variety of amino acids and higher nutrient absorption rates. Furthermore, dairy-based meat substitutes are expected to more closely resemble real animal meat products in terms of fiber fineness and sensory realism. Due to the differences in material properties between dairy and plant-based raw materials, existing plant-based meat substitute processing equipment cannot be directly applied to the processing of dairy-based meat products, necessitating the design of specialized equipment for this type of dairy food processing.

[0080] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.
[0081] Embodiments of this application provide a dairy-based meat processing apparatus (hereinafter, sometimes simply referred to as "processing apparatus") for processing dairy products, and in particular, it can be used to process dairy-based alternative meat-like products. Figure 1 As shown, dairy meat processing equipment may include a mixer 10, a conveyor 20, a twin-screw extruder 30, a fiber shaping section 40, a rapid cooling section 50, a vibrating discharge section 60, and a receiving section 70. The mixer 10, conveyor 20, twin-screw extruder 30, fiber shaping section 40, rapid cooling section 50, and vibrating discharge section 60 may be connected sequentially.
[0082] The mixer 10 can be used to mix milk-based materials and other non-milk-based ingredients (milk-based materials may include casein, whey protein, etc., and may also include fermented milk protein materials and enzyme-hydrolyzed milk protein materials, etc.). Here, the mixer 10 mainly mixes powdered materials. Preferably, the mixer 10 can be a high-speed mixer to make the mixing of various materials more uniform.
[0083] The powdered material prepared by the mixer 10 can be fed into the solid material inlet of the twin-screw extruder 30 via the conveyor 20. The solid material inlet can be located on the upper side of the twin-screw extruder 30. Preferably, the conveyor 20 can be a screw conveyor, which has advantages such as good sealing and high conveying accuracy, and can further mix the materials during transportation.
[0084] The twin-screw extruder 30 includes a drive motor 31, a control box 32, a liquid material inlet 33, and a twin-screw extrusion section 34. The drive motor 31 is connected to the twin-screw extrusion section 34 via the control box 32, which can control the output power of the drive motor 31, thereby controlling the working efficiency of the twin-screw extrusion section 34. For example, the control box 32 may include a programmable logic controller (PLC), drivers, sensors, and communicators.
[0085] like Figure 2 As shown, the twin-screw extrusion section 34 may include a first screw 341 and a second screw 342, which can mesh with each other to extrude materials during rotation. Both the liquid material inlet 33 and the solid material inlet can be located at the upstream end of the twin-screw extrusion section 34. Liquid materials (e.g., water and various excipients, food additives, nutritional fortifiers, etc. dissolved in water) can enter the twin-screw extrusion section 34 through the liquid material inlet 33 and then be further processed in the twin-screw extrusion apparatus 30.
[0086] Specifically, the twin-screw extrusion section 34 may include multiple operating sections, and the process temperatures of the multiple operating sections may not be exactly the same. Preferably, the twin-screw extrusion section 34 may include, from upstream to downstream, a material mixing section, a cooking and maturation section, a die pressurization section, and a curing and molding section. The material entering the twin-screw extrusion section 34 may pass through the above-mentioned operating sections in sequence under the action of the first screw 341 and the second screw 342.
[0087] The process includes the following sections: The material mixing section is used for mixing powdered and liquid materials, with an operating temperature of 20 to 25 degrees Celsius. The cooking and maturation section heats the mixed materials to mature them, with an operating temperature of 100 to 150 degrees Celsius, resulting in a core temperature of 80 to 130 degrees Celsius. The die-pressurizing section pressurizes the matured materials, further homogenizing them and removing volatiles and entrained gases. This section operates at 120 to 180 degrees Celsius, achieving a core temperature of 100 to 140 degrees Celsius, and maintains an internal pressure of 4 to 12 bar. The curing and shaping section initially solidifies and shapes the materials, preparing them for downstream fiber texture construction. This section operates at 100 to 150 degrees Celsius, maintaining a core temperature of 90 to 140 degrees Celsius, and maintains an internal pressure of 8 to 20 bar.
[0088] Material processed by the twin-screw extruder 30 can enter the fiber shaping section 40 to construct fiber texture, making its appearance and texture similar to animal meat. For example... Figure 3 As shown, the fiber shaping section 40 may include an extrusion chamber 41 and a stepped extrusion chamber 42. The extrusion chamber 41 may be a quasi-cylindrical chamber structure, and its chamber height (as shown in the figure) is... Figure 1 and Figure 3 The left-right direction (which is the height of the chamber, i.e. the axial direction of the fiber shaping section) is relatively small, so as to further compress the material from the twin-screw extruder 30, thereby promoting the formation of fiber texture in the milk-based material (especially milk-based protein material).
[0089] Preferably, the pressure inside the compression chamber 41 can be 4 to 15 bar.
[0090] More preferably, such as Figure 6 As shown, the extrusion chamber 41 may include a pressure balancing chamber 411 and a pressurized extrusion chamber 412. The pressure balancing chamber 411 may be located radially inner (near the center) of the extrusion chamber 41, and it may communicate with the twin-screw extruder 30. The pressurized extrusion chamber 412 may be located radially outer of the pressure balancing chamber 411. The axial length of the pressurized extrusion chamber 412 may be less than the axial length of the pressure balancing chamber 411, and the internal pressure of the pressurized extrusion chamber 412 may be greater than the internal pressure of the pressure balancing chamber 411, to further extrude the material entering the pressurized extrusion chamber 412.
[0091] The outer edge of the extrusion chamber 41 connects to the stepped extrusion chamber 42, allowing material within the extrusion chamber 41 to enter the stepped extrusion chamber 42 from its outer edge. The stepped extrusion chamber 42 can be formed in the space between two coaxial conical surfaces with a certain distance between them, the diameter of which gradually decreases axially away from the extrusion chamber 41. The inner surface of the stepped extrusion chamber 42 can be a quasi-conical structure (a portion of the conical surface), and at least a portion of its inner surface (here, the opposite sides of the two conical surfaces forming the chamber are both inner surfaces) can form quasi-conical stepped protrusions 421. Exemplarily, the stepped protrusions 421 may be arranged in one or more combinations of the following: disposed on both inner surfaces, disposed on one inner surface, or disposed on a portion of one inner surface.
[0092] like Figure 3 As shown, in the axial section of the fiber shaping section 40, the stepped protrusions may include multiple protrusions, and the radial distance from the multiple protrusions to the central axis of the fiber shaping section 40 gradually decreases in the direction away from the extrusion chamber 41. After being extruded by the extrusion chamber 41 and the stepped extrusion chamber 42, the emulsion material can form a finer fiber texture.
[0093] Preferred, such as Figure 3 As shown, in the vertical axial section of the stepped extrusion chamber 42, the angle α between the extension direction of the stepped protrusion on the inner surface of the stepped extrusion chamber 42 (the axial extension line of the inner surface, i.e., the extension line of the bottom surface of the stepped protrusion, i.e., the line connecting the tips of the stepped protrusions) and the horizontal plane ranges from 18.6 degrees to 42.8 degrees. That is, the apex angle of the conical surface containing the inner surface of the stepped extrusion chamber 42 can be from 37.2 to 85.6 degrees.
[0094] Preferred, such as Figure 3 As shown, stepped protrusions can be formed only on the inner surface of the stepped extrusion chamber 42 near the axis. Multiple protrusions of the stepped protrusions can be evenly distributed on the inner surface of the stepped extrusion chamber 42.
[0095] More preferably, such as Figure 7 As shown, the stepped protrusion 421 may include multiple protrusions, each of which may include a first arcuate portion 4211 and a second arcuate portion 4212. The first arcuate portion 4211 and the second arcuate portion 4212 may be connected, and a valley may be formed at the connection point between the first arcuate portion 4211 and the second arcuate portion 4212 relative to the first arcuate portion 4211. An appropriate drop may be formed between adjacent protrusions (that is, between the second arcuate portion 4212 of one protrusion and the first arcuate portion 4211 of another adjacent protrusion) to form a stepped structure. The above-described stepped protrusion structure is particularly suitable for fiber shaping and extrusion processing of dairy-based raw material foods.
[0096] More preferably, the central angle of the first arcuate portion 4211 can be 34 to 42 degrees, and the central angle of the second arcuate portion 4212 can be 37 to 41 degrees. The radius of curvature of the first arcuate portion 4211 can be 104 to 112 mm, and the radius of curvature of the second arcuate portion 4212 can be 69 to 73 mm. Within the parameter range of the above-mentioned arcuate portions, the stepped protrusions 421 can have good extrusion shaping ability for emulsion-based raw materials.
[0097] After fiber shaping in the fiber shaping section 40, the material can enter the rapid cooling section 50 for cooling. The rapid cooling section 50 may include a coolant inlet 51, a coolant outlet 52, and a cooling chamber 53. The cooling chamber 53 may be a tubular chamber, and a cooling jacket 531 may be provided on the outside of the cooling chamber 53. This structure can increase the heat transfer area between the material and the cooling medium, thereby improving the cooling efficiency and promoting material cooling. The temperature of the cooling chamber 53 can be 0 to 6 degrees Celsius, so that the core temperature of the material can be maintained between 40 and 70 degrees Celsius. In order to ensure that the material is sufficiently cooled, the axial length of the cooling chamber can be 300 to 1200 mm.
[0098] The coolant inlet 51 and coolant outlet 52 can be connected to an external cooling medium source for introducing and discharging cooling medium into and out of the rapid cooling unit 50 (particularly the cooling jacket 531 of the cooling chamber 53). For example, the cooling medium can be cold water. Preferably, the rapid cooling unit 50 can be provided with multiple coolant inlets 51 and multiple coolant outlets 52.
[0099] like Figure 4 and Figure 5 As shown, the vibrating discharge section 60 may include a screen 61, a sprayer 62, an ion air purifier 63, a vibrating motor 64, a liquid collection section 65, and a discharge port 66. The screen 61 may be disposed at the bottom of the vibrating discharge section 60, allowing liquid to flow out through the screen 61, while (most) solid particles are retained by the screen 61. Preferably, the mesh diameter of the screen 61 can be 2 to 4 mm, the length of the screen 61 can be 1400 to 4200 mm, and the width of the screen 61 can be 400 to 900 mm.
[0100] like Figure 4 and Figure 5As shown, the sprayer 62 may include an upper spray nozzle 621 and a lower spray nozzle 622, which are respectively disposed on the upper and lower sides of the screen 61 to fully spray the material on the screen 61. The sprayer 62 may be disposed on the portion of the screen 61 near the rapid cooling section 50, that is, the sprayer 62 may be disposed on the upstream portion of the screen 61. Preferably, the sprayer 62 may include multiple upper spray nozzles 621 and multiple lower spray nozzles 622 to enhance the spraying effect. The horizontal spacing between adjacent spray nozzles on the same side may be 100 to 300 mm. The spray pressure of the sprayer 62 may be 2 to 4 bar. The spray liquid temperature of the sprayer 62 may be 20 to 25 degrees Celsius. The spray liquid used by the sprayer 62 may include pure water, brine, or liquid containing food additives such as preservatives. The number of liquid outlet holes provided in the upper spray port 621 can be greater than the number of liquid outlet holes provided in the lower spray port 622.
[0101] The liquid collection section 65 can be located at the lower part of the screen 61, that is, at the bottom of the vibrating discharge section 60. The liquid collection section 65 can include a liquid collection tank 651 and a liquid outlet 652. The liquid collection tank 651 can be inclined so that the liquid can flow by gravity to the liquid outlet 652, and the liquid outlet 652 can be located at the lowest point of the liquid collection tank 651. The liquid sprayed by the sprayer 62 can pass through the screen 61 and enter the liquid collection section 65 after flowing through the material, and finally flow out from the liquid outlet 652.
[0102] like Figure 4 and Figure 5 As shown, the ion air blower 63 may include an upper blowing port 631 and a lower blowing port 632, which can be respectively arranged on the upper and lower sides of the screen 61 to fully blow and dry the sprayed and moistened material on the screen 61. The ion air blower 63 may be arranged in the portion of the screen 61 away from the rapid cooling section 50, that is, the ion air blower 63 may be arranged in the downstream portion of the screen 61. Preferably, the ion air blower 63 may include multiple upper blowing ports 631 and multiple lower blowing ports 632 to enhance the blowing and drying effect. The horizontal spacing between adjacent blowing ports on the same side can be 150 to 500 mm. The ion air jet pressure of the ion air blower 63 can be 3 to 6 bar.
[0103] It's understandable that ion air drying is gentler and less likely to damage materials compared to traditional hot air drying. Additionally, ion air also has the function of sterilizing and deodorizing materials.
[0104] The vibrating motor 64 can be installed at the bottom of the vibrating discharge section 60 to generate regular vibration. The vibrating motor 64 can drive the screen 61 to vibrate evenly, so that the material on the screen 61 can be evenly distributed to assist in draining and drying, and gradually transfer to the discharge port 66.
[0105] The discharge port 66 can be set at the end of the screen 61 to discharge the material after it has been sprayed and dried by the vibrating discharge section 60.
[0106] Preferred, such as Figure 4 As shown, the vibrating discharge section 60 may further include a spring column 67 and a buffer pile 68. The spring column 67 may be installed at the bottom support leg of the vibrating discharge section 60. The spring column 67 can serve as a load-bearing and elastic vibration isolation component, preventing the working vibration of the vibrating discharge section 60 from being transmitted to the foundation while bearing the load of the vibrating discharge section 60. The buffer pile 68 may be installed between the screen 61 and the bottom plate of the vibrating discharge section 60, for auxiliary support, providing damping and vibration isolation, and limiting vibration displacement.
[0107] The receiving section 70 can be used to collect processed dairy products. It can be connected to the discharge port 66 of the vibrating discharge section 60 through a pipe or the like. Alternatively, the receiving section 70 can be located below the discharge port 66 without being physically connected to it.
[0108] The following is a brief description of some of the beneficial effects of the above-described embodiments of this application.
[0109] The dairy-based meat processing equipment provided in this application improves upon existing plant-based meat processing equipment by enhancing the fiber-forming and water-retention capabilities of dairy-based raw materials, taking into account their material properties. Dairy-based meat products produced using this equipment offer improvements in nutrition, taste, and realism compared to traditional plant-based meat products.
[0110] It is understood that, in this application, when the number of parts or components is not specifically limited, the number can be one or more, where multiple refers to two or more. For cases where the number of parts or components shown in the drawings and / or described in the specification is, for example, two, three, four, etc., this specific number is generally exemplary and not restrictive, and can be understood as multiple, i.e., two or more; however, this does not mean that this application excludes the case of one.
