Description

Technical Field

[0001] This application relates to the field of dough mixing equipment technology, specifically to a vacuum dough mixer. Background Technology

[0002] Traditional dough kneading processes involve manual kneading or the use of ordinary machines. This often results in dough containing air bubbles, hindering the formation of protein gluten and leading to lower elasticity and tensile strength, making noodles or dough sheets prone to breakage. To address this issue, those skilled in the art have developed vacuum dough mixers, such as CN2877306Y, CN205213982U, and CN207400284U. However, existing vacuum dough mixers typically require removing the dough from the upper opening after kneading, which is inconvenient. Furthermore, existing vacuum dough mixers first create a vacuum before adding water, causing the flour to become fluffy. While this allows for faster mixing, the resulting dough is more mushy, with a weaker gluten network that is easily damaged during mixing, affecting its elasticity. This makes them unsuitable for kneading doughs requiring different elasticity levels, and the separate water supply process prolongs the overall kneading time. Utility Model Content

[0003] In view of this, this application provides a vacuum dough mixer to solve the technical problems of inconvenient dough handling and low controllability of dough elasticity.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A vacuum dough mixer includes a movable body, a control module and an operation panel disposed within the body, a dough mixing cylinder that is rotatably mounted on the body, and a cylinder cover that can be opened and closed at the cylinder opening. The cylinder cover is provided with a negative pressure interface connected to a negative pressure system. A dough mixing structure is installed inside the dough mixing cylinder, and the dough mixing structure is connected to a power structure disposed within the body. The body is provided with a locking structure that acts on the dough mixing cylinder. When the cylinder opening faces upward, dough mixing can be performed. When the dough mixing cylinder is rotatably mounted, the kneaded dough can be easily removed.

[0006] Furthermore, the cylinder head is hinged to the engine block.

[0007] Furthermore, a sealing structure is provided between the cylinder head and the kneading cylinder, and an inductive switch is provided on the cylinder head to detect whether the cylinder head is closed.

[0008] Furthermore, the locking structure includes a handle mounted on the kneading cylinder, the handle having a sliding lock head and an elastic element for pushing the lock head closer to the machine body, and the machine body having a locking hole that can be inserted and engaged with the lock head.

[0009] Furthermore, the control panel has a start button, a stop button, and a manual control button.

[0010] Furthermore, the machine is equipped with an emergency stop button.

[0011] Furthermore, the machine body has a mounting cavity for installing the dough kneading cylinder, and the mounting cavity has a placement platform located below the dough kneading cylinder.

[0012] Furthermore, a handle is provided on the cylinder head.

[0013] Furthermore, after the cylinder head is closed, a magnetic structure is used to reliably close the cylinder head at the opening of the kneading cylinder, and a manual pressure relief valve is provided on the cylinder head.

[0014] Furthermore, the sealing structure is a sealing strip, which has a T-shaped fixing part connected to the kneading cylinder and two concentric lips. A lip groove is formed between the two lips, and the lip groove matches the arc-shaped lip protrusion provided on the cylinder cover. The lips can press against the cylinder cover.

[0015] As can be seen from the above technical solution, the advantages of this utility model are:

[0016] The machine is mobile: This facilitates the transfer of equipment between different work scenarios and improves the utilization rate of the equipment.

[0017] The dough mixing bowl can be flipped: Compared to the traditional method of taking the dough out of the bowl, this greatly improves the convenience of taking out the dough, reduces operation time and labor intensity, and reduces the risk of contamination or damage to the dough during the removal process.

[0018] The storage platform design features a storage platform located below the kneading cylinder, which can directly receive the dough that has been turned over, making the receiving process convenient. The storage platform can also hold a dough receiving tray, facilitating dough transfer and subsequent processing, thereby improving production efficiency.

[0019] The cylinder head is easy to operate and has a good sealing performance: the cylinder head is hinged and equipped with a handle, which allows the operator to easily control the opening and closing of the cylinder head, improving the convenience and comfort of operation; the cylinder head does not rotate when the kneading cylinder rotates, avoiding accidental closure, making it more convenient and safer to use; the special structure of the sealing strip can achieve multiple seals, resulting in good sealing performance and stable negative pressure during kneading.

[0020] When using this application for dough kneading, it is safe to use, highly efficient, and the dough elasticity is controllable, making it suitable for kneading dough with different requirements. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0031] refer to Figures 1 to 7 ,like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a vacuum dough mixer, which mainly consists of a movable body 1, a control module and an operation panel 5 housed within the body 1, a dough mixing cylinder 2 that is flipped and mounted on the body 1, and a cylinder cover 3 that can be opened and closed and located at the opening of the dough mixing cylinder 2. The cylinder cover 3 is provided with a negative pressure interface 31 connected to the negative pressure system. This structural design gives the dough mixer significant advantages in terms of ease of operation, dough processing efficiency, and adaptability to the production needs of different dough products. The mobility of the body 1 facilitates the transfer of the equipment between different working scenarios and improves the utilization rate of the equipment.

[0032] Specifically, the machine body 1 serves as the basic support structure of the entire dough mixer. The bottom of the machine body 1 is equipped with wheels for movement. It contains a control module to precisely control various operating parameters of the equipment, ensuring the stability and accuracy of the dough mixing process. The machine body 1 has an installation cavity 11 for mounting the dough mixing cylinder 2. The installation cavity 11 has a placement platform 12 located below the dough mixing cylinder 2. When the dough mixing cylinder 2 is flipped over to remove the kneaded dough, the placement platform 12 can directly receive the dough, making the dough receiving process convenient and avoiding damage or contamination caused by the dough falling directly.

[0033] Preferably, a dough receiving tray can be placed on the storage platform 12, which further facilitates the transfer and subsequent processing of the dough and improves production efficiency.

[0034] In this application, the dough mixing cylinder 2 is rotatably mounted on the machine body 1. A dough mixing and stirring structure is installed inside the dough mixing cylinder 2, movably mounted within it via bearings. This structure is connected to a power structure located within the machine body 1. Driven by the power structure, the dough mixing and stirring structure can thoroughly mix the flour, water, and other necessary materials placed in the dough mixing cylinder 2, ensuring the dough is evenly mixed. The rotatable action of the dough mixing cylinder 2 is independent of the action of the dough mixing structure. When the opening of the dough mixing cylinder 2 faces upwards, dough mixing can be performed. After the dough mixing cylinder 2 is rotatably mounted, the rotation of the dough mixing structure allows for quick removal of the dough. The process of removing the dough is easy and labor-saving with minimal manual assistance, making it convenient and easy to remove. This rotatable design is a major innovation of this application. Compared to the traditional method of removing dough from the opening of a vacuum dough mixer, it greatly improves the convenience of dough removal, reduces operating time and labor intensity, and also reduces the difficulty of removing the dough.

[0035] In this application, the bottom of the dough mixing bowl 2 is arc-shaped, which can be well matched with the dough mixing structure to avoid dead corners where flour residue will affect the uniformity of dough mixing.

[0036] The cylinder head 3 is hinged to the machine body 1 and can rotate relative to the machine body 1, thereby opening or closing the kneading cylinder 2. When the kneading cylinder 2 rotates, the cylinder head 3 does not rotate with it, thus avoiding the possibility of accidental closure of the cylinder head 3 during the rotation of the kneading cylinder 2, making it more convenient and safer to use. To further facilitate the operation of the cylinder head 3, a handle 32 is provided on the cylinder head 3. When it is necessary to open or close the cylinder head 3, the operator only needs to operate the handle 32 to easily control the rotation of the cylinder head 3 relative to the kneading cylinder 2, thereby controlling the opening and closing of the cylinder head 3, improving the convenience and comfort of operation.

[0037] A sealing structure is provided between the cylinder head 3 and the kneading cylinder 2. This sealing structure effectively improves the sealing performance between the cylinder head 3 and the kneading cylinder 2, resulting in better negative pressure. During the kneading process, good sealing ensures the normal operation of the vacuum system, providing a stable environment for vacuuming and degassing after the flour and water are mixed. Simultaneously, the cylinder head 3 is equipped with a sensor switch to detect whether it is closed. Preferably, this sensor switch is a push-button switch used in conjunction with the kneading cylinder 2. When the cylinder head 3 is not fully closed, the sensor switch will send a signal, preventing the equipment from initiating vacuuming or other operations. This avoids safety accidents caused by an unclosed cylinder head and improves the safety of equipment operation.

[0038] In order to make the kneading cylinder 2 tiltable and able to maintain a stable kneading position, such as Figure 5 As shown in the present application, one structure of the locking structure 4 is as follows: the locking structure 4 includes a handle 41 installed on the kneading cylinder 2, the handle 41 is provided with a sliding lock head 43 and an elastic member 44 for pushing the lock head 43 toward the machine body 1, and the machine body 1 is provided with a locking hole 13 that can be inserted and cooperate with the lock head 43.

[0039] Specifically, one end of the dough kneading cylinder 2 is mounted on the main body of the machine body 1 via a bearing, and the other end of the dough kneading cylinder 2 is mounted on the pin lug of the machine body 1 via a bearing. The handle 41 is located outside the pin lug, the locking head 43 slides axially, and the locking hole 13 that works in cooperation with the locking head 43 is located on the pin lug. Preferably, in this application, there are two locking holes 13, which are used to lock the dough kneading position and the dough reversing position of the dough kneading cylinder 2 respectively.

[0040] In this application, another structure of the locking structure 4 is as follows: The locking structure 4 includes a handle 41 hinged to the kneading cylinder 2. When the cylinder opening of the kneading cylinder 2 faces upward, the handle 41 can swing up and down. A limiting block 42 that engages with the fork of the handle 41 is fixed on the machine body 1 to prevent the kneading cylinder 2 from flipping. Preferably, the limiting block 42 is located on the axial tangential plane. When the fork of the handle 41 engages with the limiting block 42, the kneading cylinder 2 can be stably stopped in the kneading position, ensuring that the kneading cylinder 2 will not automatically flip during the kneading process, thus ensuring the stability of the kneading and mixing process. Quality; In order to make the handle 41 more stably cooperate with the limit block 42, the end of the handle 41 that cooperates with the limit block 42 is provided with a counterweight or the hinge of the handle 41 is provided with a torsion spring. In this way, even if the handle 41 is vibrated, it is not easy to separate from the limit block 42, which further improves the reliability of the locking structure. When driving the dough mixing cylinder 2 to flip, one hand can hold the handle 41 to control the flipping angle of the dough mixing cylinder 2. After the handle 41 rotates with the dough mixing cylinder 2 at a certain angle, it can re-cooperate with the limit block 42 or cooperate with other limiting structures to lock in the reverse position.

[0041] In actual use, the locking structure 4 can also be a sliding rod set on the machine body 1. The dough mixing cylinder 2 has a hole that cooperates with the sliding rod. The hole is parallel to the axis of the dough mixing cylinder 2. An elastic force acts on the sliding rod so that the sliding rod can be stably inserted into the hole, so that the dough mixing cylinder 2 is stably kept in the dough mixing position.

[0042] In order to ensure that the cylinder cover 3 can reliably close onto the kneading cylinder 2 after closing, thus providing a certain degree of sealing to the kneading cavity, the cylinder cover 3 is reliably closed at the opening of the kneading cylinder 2 using a magnetic attraction structure 7. The magnetic attraction structure 7 provides a certain pre-tightening force to the cylinder cover 3 after closing. The cylinder cover 3 is equipped with a manual pressure relief valve. After kneading is completed, the kneading cavity can be quickly connected to the outside through the manual or automatic pressure relief valve, allowing the kneading cavity to return to normal pressure and facilitating the opening of the cylinder cover 3.

[0043] like Figure 6 and Figure 7 As shown, in order to improve the sealing performance of the joint between the cylinder head 3 and the kneading cylinder 2, reduce the energy consumption of the negative pressure system, and achieve a stable negative pressure effect, the sealing structure is a sealing strip 8. The sealing strip 8 has a T-shaped fixing part 81 connected to the kneading cylinder 2 and two concentric lips 82. The T-shaped fixing part 81 ensures the stable installation of the sealing strip 8. A lip groove 83 is formed between the two lips 82. The lip groove 83 cooperates with the arcuate lip protrusion 33 provided on the cylinder head 3, and the lips 82 can press against the cylinder head 3. The cooperation between the lips 82 and the cylinder head 3, and the cooperation between the arcuate lip protrusion 33 and the lip groove 83, make the joint between the cylinder head 3 and the kneading cylinder 2 a multi-seal state with good sealing effect. Even when the sealing strip 8 has slight wear, the multi-seal characteristics can still make the sealing strip 8 have a good sealing effect and extend the service life of the sealing strip 8.

[0044] In this application, the operation panel 5 has a start button, a stop button, and a manual control button. Operators can flexibly control the start and stop of the equipment and perform manual operation through these buttons according to different kneading needs, so as to meet diverse production requirements. The machine body 1 is also equipped with an emergency stop button 6. In case of an emergency, the operator can quickly press the emergency stop button 6 to stop the equipment immediately, so as to ensure the personal safety of the operator and the safety of the equipment.

[0045] When using this application, since only a negative pressure adsorption structure is set on the cylinder cover 3, flour and water are added before the cylinder cover 3 needs to be closed. The flour and water are mixed and stirred before vacuuming and degassing. The technical advantages of this process are: during the vacuuming process, air is released and negative pressure is generated, which accelerates the penetration of water into the flour particles. This premixing method shortens the water penetration path, increases the water penetration speed, ensures rapid and uniform water distribution, avoids local over-wetness or over-dryness, and improves the consistency of the dough. Moreover, by controlling the vacuum degree, the elasticity of the dough can be flexibly controlled. For example, when making steamed buns, reducing the vacuum degree can reduce the elasticity of the dough and prevent the finished product from shrinking; when making dried noodles, increasing the vacuum degree can enhance the gluten strength and shorten the dehydration time. It can be used for dough and flour with different needs, which greatly improves the versatility and adaptability of the equipment. Furthermore, this vacuum system only requires degassing the mixed dough. Since the dough itself occupies a certain space, this reduces the space required for subsequent vacuum processing. Compared to the process of adding flour first, then vacuuming, then adding water and kneading (which causes the dough to fluff due to negative pressure, prolonging the degassing time), this reduces energy consumption and minimizes flour leakage in a vacuum environment, improving the working environment. Moreover, because the dough forms a gluten network in the early stages of mechanical mixing, this dough mixer uses a process of mixing first and then vacuuming. Compared to the traditional method of mixing while the flour is fluffy, the dough produced by this invention has a denser and stronger gluten network. After the initial formation of the gluten network through mechanical mixing, the vacuum environment further promotes water penetration, making the gluten network even more complete. This synergistic effect ensures efficient gluten formation and avoids damage to the gluten network caused by mixing during the initial stretching under negative pressure, helping to maintain the dough's elasticity and chewiness, and improving the texture and quality of the finished products.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
