Description

Technical Field

[0001] The utility model belongs to the field of food processing technology equipment, and more specifically, relates to a double-sided rolling and kneading machine used in the dough strip rolling technology stage of high-water-added noodle product processing. Background Art

[0002] Industrialized production is a major development trend in the noodle processing industry, and calendering is a key process in noodle production. Only through the rolling action of rollers can the loose, scattered gluten in the dough after kneading form a continuous network structure, resulting in a dough sheet with a certain toughness and strength. The calendering ratio is a key factor affecting the processing properties of the dough sheet and the quality of the noodles. A too low calendering ratio hinders the full development of the gluten, while a too high calendering ratio introduces excessive energy into the dough sheet, disrupting the gluten network. Therefore, as the calendering ratio increases, the storage modulus and loss modulus of the dough sheet first increase and then tend to remain constant. An appropriate number of calendering cycles ensures that the starch in the dough sheet is tightly bound to the gluten network, creating a dense and stable gluten network structure, thereby improving the mechanical properties of the dough sheet and enhancing its elasticity, fracture stress, and fracture strain. Traditional calendering methods use multiple calendering rollers to gradually thin the dough sheet to the desired thickness for noodle production. This method has little effect on improving noodle quality and taste, and is significantly inferior to hand-rolled noodles. High-quality calendering of high-moisture dough or dough sheets is also a challenge facing existing technologies. Utility Model Content

[0003] In order to solve the problem that the quality and taste of noodles in traditional calendering are not significantly improved, the utility model provides a double-sided rolling and kneading method, which draws on and imitates the traditional manual rolling method, incorporates the rolling and kneading technology into the processing, and improves the gluten network structure in the noodle strip by multiple rolling and kneading on the front and back sides, while making the micropore structure more uniform, thereby improving the quality of the noodle strip.

[0004] The technical solutions adopted are as follows:

[0005] A double-sided rolling and kneading machine includes a frame and calendering rollers arranged on the frame, the calendering rollers include a first calendering roller and a second calendering roller arranged in parallel, the first calendering roller is located above the second calendering roller, and the dough sheet passes through the first calendering roller and the second calendering roller in sequence, the first calendering roller kneads one side of the dough sheet, and the second calendering roller kneads the other side of the dough sheet.

[0006] Furthermore, the first calendering roller includes a rolling roller I and a support roller I, the rolling roller I is located on the upper side of the support roller I, and is used to roll and knead the upper side of the surface strip, and the second calendering roller includes a rolling roller II and a support roller II, the rolling roller II is located on the lower side of the support roller II, and is used to roll and knead the lower side of the surface strip.

[0007] Furthermore, the driving end of the rolling and kneading roller I is provided with a driving motor I, the driving end of the rolling and kneading roller II is provided with a driving motor II, a gear transmission is formed between the rolling and kneading roller I and the supporting roller I, and a gear transmission is formed between the rolling and kneading roller II and the supporting roller II.

[0008] Furthermore, the first calendering roller and the second calendering roller are respectively provided with encoders for calculating and regulating their corresponding rotational speeds.

[0010] Preferably, the outer layers of the first calendering roller and the second calendering roller in contact with the dough strip are food-grade polytetrafluoroethylene anti-sticking layers.

[0011] Preferably, the support roller I and the support roller II are cylindrical pressure rollers with smooth or textured surfaces.

[0012] The technical solution of this utility model has the following advantages:

[0013] A. This double-sided rolling and kneading machine draws inspiration from the traditional artisan rolling and kneading techniques used in traditional handmade noodle making. After the dough sheet passes through two sets of calendering rollers, the rolling and kneading rollers sequentially form single-sided transverse corrugations on both the upper and lower surfaces, simulating manual kneading. This kneading process promotes the formation of the gluten network within the dough sheet, resulting in a smoother and more delicate surface and a chewy, elastic texture. Conveyor belts are installed at the entrance and exit of the dough sheet, and the speed of the dough sheet is adaptively matched and controlled at each location, ensuring smoother rolling and kneading.

[0014] B. The outer layers of all the dough rollers included in the first calendering roller and the second calendering roller in the present invention are made of food-grade polytetrafluoroethylene anti-stick material to prevent high-moisture dough from adhering to the calendering roller.

[0027] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1 and Figure 2As shown, the present invention provides a double-sided rolling and kneading machine, comprising a frame 1 and calendering rollers mounted on the frame 1. The calendering rollers include a first calendering roller 2 and a second calendering roller 3 arranged in parallel. The first calendering roller 2 is located above the second calendering roller 3. A dough sheet 4 passes through the first calendering roller 2 and the second calendering roller 3 in sequence. The first calendering roller 2 rolls and kneads one side of the dough sheet 4, while the second calendering roller 3 rolls and kneads the other side of the dough sheet 4, thereby kneading both sides of the dough sheet. In the present invention, the first calendering roller is preferably positioned above the frame 1, and the second calendering roller 3 is positioned below the frame 1. Two sets of calendering rollers are arranged above and below the frame 1. The first calendering roller 2 includes a rolling and kneading roller I21 and a support roller I22. The rolling and kneading roller I21 is located above the support roller I22 and is used to roll and knead the upper side of the dough sheet 4. The second calendering roller 3 includes a rolling and kneading roller II31 and a support roller II32. The rolling and kneading roller II31 is located below the support roller II32 and is used to roll and knead the lower side of the dough sheet 4. Rolling roller I21 is driven by a drive motor I23, while rolling roller II31 is driven by a drive motor II33. A gear transmission is formed between rolling roller I21 and support roller I22, and between rolling roller II31 and support roller II32. Both drive motors I23 and II33 are variable-frequency motors. Drive motor I23 controls the first calendering roller 2, its speed calculated and regulated by the speed signal of the preceding dough sheet. Drive motor II33 controls the second calendering roller 3, its speed calculated and regulated by the encoder signal of the first calendering roller 2. The encoder signal on the second calendering roller 3 is transmitted to subsequent equipment. Support rollers I22 and II32 are cylindrical rollers with smooth or textured surfaces, serving as a support platform for the dough sheet during rolling.

[0029] As a further preferred embodiment of the present invention, a plurality of cylindrical curved surfaces a are respectively provided on the roller surfaces of the rolling and kneading roller I21 and the rolling and kneading roller II31 along their axial directions. The cylindrical curved surfaces a are arranged at intervals along their circumferential surfaces, similar to manual rolling pins. The radius of the curved surface is preferably 18 mm. When the rolling and kneading rollers rotate, the dough strip 4 is rolled and kneaded to form unilateral transverse corrugations of the dough strip 4.

[0030] After the dough belt 4 passes through two sets of calendering rollers, single-sided transverse corrugations are formed on the upper and lower surfaces in turn under the action of rolling and kneading rollers I21 and II31, simulating the manual kneading method, rolling and kneading the front and back sides of the dough belt 4, promoting the formation of the gluten network inside the dough belt 4, making the surface of the dough belt 4 smoother and more delicate, and at the same time giving the noodles a chewy and elastic taste.

[0031] During use, conveyor belts are installed at the dough sheet entrance and exit (b) and exit (c) of the rolling and kneading machine. Adaptive matching and control of the dough sheet speed at each location ensure smoother rolling and calendering of the dough sheet. The entrance conveyor belt is located on the upper right side of the first calendering roller. The dough sheet enters the rolling and kneading machine from above via the entrance conveyor belt, passes through the first and second calendering rollers in sequence, and after being kneaded and calendered by both sets of calendering rollers, enters the next processing stage and is delivered via the exit conveyor belt. The utility model alternates the two pairs of rolling and kneading rollers, forming upper corrugations on the surface of the dough sheet 4 after passing through the first calendering roller 2 and lower corrugations on the surface after passing through the second calendering roller 3. This achieves double-sided rolling and kneading of the dough sheet 4, with a calendering ratio of 40% on the upper side and 30% on the lower side.

[0032] As a further preferred embodiment of the present invention, encoders 5 for calculating and controlling the corresponding rotational speeds are respectively provided on the first calendering roller 2 and the second calendering roller 3. This effectively controls the rolling and kneading speed and improves the quality of the dough sheet 4. The encoder on the first calendering roller 2 is mounted on a gear at one end of the rolling and kneading roller I, while the encoder on the second calendering roller 3 is mounted on a gear at one end of the support roller II 32.

[0033] As a further preferred embodiment of the present invention, the outer layer of the first calendering roller 2 and the second calendering roller 3 in contact with the dough strip 4 is a food-grade polytetrafluoroethylene anti-stick layer, which is used for calendering dough strips with a moisture content of 36-42% and an applicable thickness of 10-60 mm.

[0034] Any matters not described in this utility model are applicable to the prior art.

[0035] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
