Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically a preparation process for a cream-like product, bone broth, and related preparation equipment. Background Technology

[0002] Most bone broth seasonings on the market currently use the protein in the product to directly coat the oil during the production process. As a result, the oil content of the products produced is relatively low, and the taste is slightly bland, lacking in richness and aftertaste. If a large amount of oil is added, the protein in the material has limited coating ability and cannot completely coat the oil, resulting in poor enhancement of the oil flavor and richness of the product. In addition, the product has poor stability and is prone to oil separation.

[0003] Furthermore, in the production of cream-like products, the raw materials are first emulsified using mixing tanks and emulsifiers. The emulsified mixture is then homogenized in a homogenizer. Because the stirring and emulsification processes cannot completely ensure the raw materials are thoroughly dispersed, filtration is required before homogenization. In industrial production, mesh filters are typically used, which often results in slurry-like material clogging the mesh. Avoiding mesh clogging can reduce the amount of starch added, but the flavor and texture of the product will slightly decrease. Therefore, general homogenizing equipment is insufficient for homogenizing the aforementioned mixture. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a preparation process for a cream-like product that can form a stable fat encapsulation system. This cream-like product is suitable for bone broth seasoning packets. This invention also provides related preparation equipment for the aforementioned cream-like product.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In the first technical solution, a preparation process for a cream-like product includes, According to the weight ratio, add 90-110 parts of warm water at about 60℃ and 18-22 parts of starch to the mixing tank and stir and emulsify thoroughly; draw in 45-50 parts of melted lard, control the temperature at 50±2℃, and emulsify thoroughly; then draw in the remaining 32 parts of lard, and emulsify thoroughly until the product is a uniform emulsion without obvious oil separation; keep the temperature constant and homogenize the above materials at a homogenization pressure of 40-45Mpa to obtain a silky cream-like product.

[0006] In the second technical solution, a bone broth base uses a cream-like product, which is a cream-like product obtained using the preparation process of the cream-like product as described in the first technical solution.

[0007] In the third technical solution, a homogenizing valve includes... A housing, the interior of which includes a cavity, the housing having an inlet pipe communicating with the cavity, and an outlet pipe communicating with the cavity and located on the side of the inlet pipe of the housing. A blocking element is disposed in the cavity, and an annular first gap is formed between the blocking element and the inner wall of the housing. The first gap is located between the feed pipe and the discharge pipe, and the axis of the first gap coincides with the axis of the discharge pipe. The inner wall of the shell, corresponding to the area between the first gap and the discharge pipe, is a flow surface with a gradually decreasing cross-sectional diameter and a smooth transition.

[0008] In the third technical solution, as a preferred embodiment, a plurality of prisms arranged in a ring array are provided on the flow surface. The first end of the prism is located near the outlet pipe port, the prism extends along the flow surface, and the second end faces the first gap.

[0009] In the third technical solution, preferably, the cross-section of the prism is conical.

[0010] In the third technical solution, as a preferred embodiment, a support member is further provided between the discharge pipe and the blocking member, and the four sides of the support member are connected to the first end of the prism.

[0011] In the third technical solution, preferably, a supporting surface is provided near the first end of the prism, and the supporting surface of all the prisms is part of a spherical surface. The blocking member is a spherical member and can be stably placed on the spherical surface.

[0012] In the third technical solution, preferably, the blocking member is a spherical member.

[0013] In the third technical solution, as a preferred embodiment, the housing includes a first housing and a second housing, the connection between the first housing and the second housing is located between a first gap and a feed pipe, and the inner wall of the housing is a complete and continuous curved surface in the portion between the first gap and the discharge pipe.

[0014] In the fourth technical solution, a homogenizing unit includes a buffer and at least two homogenizing valves as described in any one of the third technical solutions. The buffer includes a container and an exhaust pipe, with homogenizing valves connected in series. The container is positioned between the discharge pipe of the upstream homogenizing valve and the inlet pipe of the downstream homogenizing valve. A flow sensor is installed inside the container. The first end of the exhaust pipe is connected between the container and the upstream homogenizing valve, and the second end of the exhaust pipe is a free end. A solenoid valve is installed on the exhaust pipe, and the solenoid valve is signal-connected to the flow sensor.

[0015] The beneficial effects of using this invention are: This invention uses lard, starch, and water through pre-emulsification and homogenization processes to form a stable fat encapsulation system. The raw materials are simple, the production method is convenient and easy to operate, and the product is stable and easy to use. Adding this product to bone broth products can significantly enhance the flavor, make the aftertaste more fragrant and mellow, and make the product stable, delicate and silky, thereby improving the quality of the products used and appropriately reducing the product cost.

[0016] The homogenizing valve proposed in this invention homogenizes high-pressure fluid mixtures. It accelerates the fluid flow rate through a first gap and achieves homogenization through fluid convergence and collision. When encountering particles or insufficiently mixed materials, the blocking component can move to avoid them, eliminating the need for a filter screen. Insufficiently mixed materials are crushed by collision, which facilitates the smooth progress of the homogenization process and improves the stability of the homogenization process.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0028] A process for preparing a cream-like product includes: adding 90-110 parts of warm water at approximately 60°C and 18-22 parts of starch to a mixing tank by weight, and stirring and emulsifying thoroughly; drawing in 45-50 parts of melted lard, controlling the temperature at 50±2°C, and emulsifying thoroughly; then drawing in the remaining 32 parts of lard, and emulsifying thoroughly until the product is a uniform emulsion without obvious fat separation; keeping the temperature constant, homogenizing the above-obtained material under a homogenization pressure of 40-45 MPa to obtain a silky cream-like product.

[0029] The specific operation process is as follows: 1) First, put 100 parts of warm water at about 60℃ into the mixing tank, then add 20 parts of starch, stir and emulsify for 10-15 minutes, and check that the starch solution is uniform and free of lumps.

[0030] 2) Add 48 parts of melted, transparent lard, keep the overall temperature at 50±2℃, and emulsify for 10-15 minutes; then add the remaining 32 parts of lard in the same state and emulsify for 15-20 minutes to make the product a uniform emulsion without obvious oil separation.

[0031] 3) Keep the temperature constant and transport the material into another mixing tank through a high-pressure homogenizer. The homogenization pressure is 40-50 MPa. The material is a silky paste-like cream product with good fat coating. After packaging, the finished product is obtained.

[0032] This invention uses lard, starch, and water through pre-emulsification and homogenization processes to form a stable fat encapsulation system. The raw materials are simple, the production method is convenient and easy to operate, and the product is stable and easy to use. Adding this product to bone broth products can significantly enhance the flavor, make the aftertaste more fragrant and mellow, and make the product stable, delicate and silky, thereby improving the quality of the products used and appropriately reducing the product cost.

[0036] 3) Keep the temperature constant and transport the material into another mixing tank through a high-pressure homogenizer. The homogenization pressure is 40 MPa. The material is a silky paste-like cream product with good fat coating. After packaging, the finished product is obtained. Example 2

[0037] An embodiment of the preparation process for the above-mentioned cream-like product can be carried out according to the following steps.

[0040] 3) Keep the temperature constant and transport the material into another mixing tank through a high-pressure homogenizer. The homogenization pressure is 45 MPa. The material is a silky paste-like cream product with good fat coating. After packaging, the finished product is obtained. Example 3

[0043] 2) Pump in 72 kg of melted, transparent lard, maintain the overall temperature at 50°C, and emulsify for 20 minutes; then pump in the remaining 48 kg of lard in the same state, emulsify for 20 minutes, so that the product is a uniform emulsion without obvious oil separation.

[0044] 3) Keep the temperature constant and transport the material into another mixing tank through a high-pressure homogenizer. The homogenization pressure is 45 MPa. The material is a silky paste-like cream product with good fat coating. After packaging, the finished product is obtained. Example 4

[0045] In the aforementioned process for preparing cream-like products, even after emulsifying the mixture of water, starch, and lard as thoroughly as possible, it is still impossible to guarantee a completely ideal mixture. When lumps or large inclusions are present in the mixture, conventional filtration using a mesh screen is necessary. However, due to the viscosity of the mixture, the flow rate through the mesh screen decreases, and the screen is prone to clogging. Furthermore, using a plunger pump to pressurize and transport the material for homogenization presents difficulties. Therefore, this invention also proposes homogenization-related equipment to address the problems encountered in the production of the aforementioned cream-like products. It should be noted that the homogenization-related equipment proposed in this invention can also be used for homogenization processes of other materials, particularly suitable for homogenizing colloids or viscous fluids. In this embodiment, the homogenization-related equipment is the core component of the homogenization equipment: the homogenization valve 1.

[0046] Specifically, a homogenizing valve 1 includes a housing 10, which has an internal cavity. The housing 10 has an inlet pipe 111 communicating with the cavity and an outlet pipe 121 communicating with the cavity and located on the side of the housing 10 opposite to the inlet pipe 111. A blocking member 20 is disposed in the cavity, and an annular first gap A is formed between the blocking member 20 and the inner wall of the housing 10. The first gap A is located between the inlet pipe 111 and the outlet pipe 121, and the axis of the first gap A coincides with the axis of the outlet pipe 121. The area of ​​the inner wall of the housing 10 corresponding to the first gap A and the outlet pipe 121 is a flow surface with a gradually decreasing cross-sectional diameter and a smooth transition.

[0047] like Figure 1 As shown, the homogenizing valve 1 in this embodiment mainly includes a housing 10 and a blocking member 20. The housing 10 includes a first housing 11 and a second housing 12. Both the first housing 10 and the second housing 12 have hemispherical or near-hemispherical inner walls. The tail of the first housing 11 is provided with an inlet pipe 111, and the tail of the second housing 12 is provided with an outlet pipe 121. The first housing 11 and the second housing 12 can be connected to each other through their external connecting structures to form a spherical or near-spherical cavity inside the housing 10. In this embodiment, the outer wall of the open port at the front of the first housing 11 has a threaded structure, and the open port at the front of the second housing 12 is slightly open outward to form a stepped structure. The inner ring surface of the stepped structure also has a threaded structure. The first housing 11 and the second housing 12 can be connected to each other through the threaded structure to form a structure such as Figure 1 As shown in the diagram. After the first housing 11 and the second housing 12 are combined, their inner walls are connected and the connection is smooth. Ideally, the connection between the two housings forms a continuous surface. At this time, the feed pipe 111, the discharge pipe 121, and the cavity inside the housing 10 are coaxial.

[0048] In this embodiment, the blocking member 20 is a spherical structure. In other embodiments, the blocking member 20 may also be a structure with a cylindrical center and a curved surface near the end of the discharge pipe 121. The maximum lateral outer diameter of the blocking member 20 is A, and the inner diameter of the cavity of the housing 10 corresponding to the maximum outer diameter of the blocking member 20 is B. A and B satisfy the relationship 1.6mm ≤ (BA) ≤ 2.0mm. When the blocking member 20 is placed in the cavity inside the housing 10, an annular first gap A with a width between 0.8mm and 1.0mm is formed between the blocking member 20 and the inner wall of the housing 10.

[0049] like Figure 4 As shown, the area between the first gap A and the discharge pipe 121 on the inner wall of the shell 10 is a flow surface with a gradually decreasing cross-sectional diameter and a smooth transition. Several annularly arranged prisms 122 are arranged on the flow surface. The first end of each prism 122 is located near the port of the discharge pipe 121, and the second end of the prism 122 extends along the flow surface and faces the first gap A. When the mixture flows into the cavity from the feed pipe 111, it passes through the first gap A. The total area of ​​the first gap A is less than the total cross-sectional area of ​​the other cavities within the shell 10. Therefore, the mixture flows faster due to the Venturi effect. After being guided by the flow surface, the mixture changes direction and collides at the collision zone C, achieving both cavitation and impact effects, thus ensuring sufficient homogenization of the mixture.

[0050] like Figure 5 As shown, when the mixture contains incompletely emulsified materials, such as larger particles, entering the first gap A through the feed channel 112, the blocking member 20 can tilt or move to one side, changing the width of the first gap A—that is, increasing the width on one side and decreasing the width on the other. Therefore, larger particles can pass through the first gap A without clogging it. Additionally, as... Figure 5 As shown, after the blocking member 20 moves to the right, the width of the first gap A on the left increases and the width of the first gap A on the right decreases. The speed at which the mixture passes through the first gap A on the right increases slightly. After the mixture on both sides collides in the collision zone C, it can also crush larger particles to a certain extent and finally flow out through the discharge channel 123.

[0051] Preferably, since the mixture travels at a very high speed after passing through the first gap A, to avoid the mixture impacting the prism 122 and causing it to break, as follows: Figure 3 As shown, the cross-section of prism 122 is conical.

[0052] In addition, such as Figure 2As shown, due to the setting of prism 122, a second gap B is formed above the flow surface and between two adjacent prisms 122. The second gap B decreases in diameter from the outside to the inside, which can further increase the outflow velocity of the mixture, make the collision of the mixture more intense, and optimize the homogenization effect.

[0053] A support member 1221 is also provided between the discharge pipe 121 and the blocking member 20. The four sides of the support member 1221 are connected to the first end of the prism 122. The support member 1221 has two main functions: first, it serves as a support platform for the blocking member 20; second, it forms a baffle above the collision zone C to prevent the mixture from interfering with the position of the blocking member 20 after colliding in the collision zone C.

[0054] In this embodiment, the housing 10 includes a first housing 11 and a second housing 12. The connection between the first housing 11 and the second housing 12 is located between the first gap A and the feed pipe 111. The inner wall of the housing 10 between the first gap A and the discharge pipe 121 is a complete and continuous curved surface. To avoid difficulty in achieving the required machining precision at the connection between the first housing 11 and the second housing 12, a connection is formed. To prevent the connection from interfering with the flow direction control of the mixture after passing through the first gap A, the connection between the first housing 11 and the second housing 12 can be as close as possible to the feed pipe 111, so that the inner wall of the housing 10 is an integral surface from the first gap A to the discharge pipe 121. Example 5

[0055] This embodiment is based on the homogenizing valve 1 in embodiment 4, but changes the structure of the prism 122 in the homogenizing valve 1 and fixes the buffer 2.

[0056] like Figure 6 and Figure 7 As shown, a support surface 1222 is provided near the first end of the prism 122. The support surface 1222 of all prisms 122 is part of a spherical surface. The blocking member 20 is a spherical member and can be stably placed on the support surface 1222. Therefore, the second gap B is relatively fixed. Although it cannot allow the blocking member 20 to swing, it can stabilize the cross-sectional area of ​​the second gap B, so that the mixture collides in a fixed area. Example 6

[0057] like Figure 8As shown, this embodiment proposes a homogenizing unit, including a buffer 2 and at least two homogenizing valves 1 used in the above embodiments 4 or 5. The buffer 2 includes a container 21 and an exhaust pipe 22. The homogenizing valves 1 are connected in series. The container 21 is located between the discharge pipe 121 of the upstream homogenizing valve 1 and the inlet pipe 111 of the downstream homogenizing valve 1. A flow sensor 211 is installed inside the container 21. The first end of the exhaust pipe 22 is connected between the container 21 and the upstream homogenizing valve 1. The second end of the exhaust pipe 22 is a free end. A solenoid valve 221 is installed on the exhaust pipe 22. The solenoid valve 221 is signal-connected to the flow sensor 211. The homogenizing valve 1 and the buffer 2 can be connected by a flange 3.

[0058] In this embodiment, the homogenizing unit ensures that the feed pipe 111 of the downstream homogenizing valve 1 is always filled with the mixture, preventing air from entering the feed pipe 111. If air is mixed into the feed, the mixture will splash when passing through the first gap A, making it impossible to ensure that the mixture collides with the other side in the collision zone C. Therefore, the added buffer 2 solves this problem.

[0059] Open the solenoid valve 221 to ensure that the exhaust pipe 22 is unobstructed. After the mixture enters the downstream homogenizing valve 1, the air is first discharged from the exhaust pipe 22. When the liquid level of the mixture gradually rises to the flow sensor 211, the flow sensor 211 forms a control signal, and the system issues a command to control the solenoid valve 221 to close, so that the entire homogenizing unit can operate smoothly.

[0060] like Figure 9 As shown, in other embodiments, multiple homogenization units can be connected in parallel to increase the speed of the homogenization process.

[0061] The above content is only a preferred embodiment of the present invention. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the ideas of the present invention. As long as these changes do not depart from the concept of the present invention, they all fall within the protection scope of this patent.
