Description

A constant temperature noodle machine Technical Field

[0001] The invention relates to a constant temperature noodle making machine. Background Art

[0002] A dough mixer is a food machine that evenly mixes flour, water, and other ingredients to form dough suitable for various pasta dishes. However, during the dough mixing process, the high-speed friction between the mixing tool and the drum wall causes the dough temperature to gradually rise. If the dough temperature exceeds 30°C, the yeast in the dough will react, even burning the yeast and causing it to lose its fermentation function, resulting in the dough becoming scrapped and uneaten.

[0003] Conventional dough mixers also include a cooling water guide tray body, which supports the inner wall of the dough barrel. The upper end of the tray body is fixedly connected to the inner wall of the dough barrel, while the lower end or side surface of the tray body engages the outer wall of the dough barrel to seal the heat exchange cavity. The tray body is axially defined with a water inlet hole and a water outlet hole spaced apart from the inlet hole. The inlet hole communicates with the second end of the water inlet channel, while the outlet hole communicates with the second end of the water outlet channel. The upper end of the tray body is recessed to form a water inlet trough and a water outlet trough. One end of the water inlet trough communicates with the water inlet hole, while the other end extends through the side wall of the tray body and communicates with the heat exchange cavity. One end of the water outlet trough is connected to the water outlet hole, while the other end extends through the side wall of the tray body and communicates with the heat exchange cavity. During operation, water flows along the following path: water inlet → water inlet hole → water inlet trough → heat exchange cavity → water outlet trough → water outlet hole → water outlet channel. The water flow is guided by the inlet and outlet troughs, facilitating circulation of cooling water around the bottom of the noodle bucket and providing stable cooling. This ensures the fluidity of the cooling water at the bottom of the noodle bucket's inner wall. However, this type of tray is prone to water flowing through it during inlet and outlet, affecting cooling efficiency. Summary of the Invention

[0033] As shown in Figures 1-8, this embodiment provides a constant temperature noodle machine, including a noodle barrel 10, a rotating shaft 30, a disc 40 and a heat exchange pipe 50, a first heat exchange cavity 20 is formed between the inner wall 101 of the noodle barrel 10 and the outer wall 102 of the noodle barrel 10; the rotating shaft 30 is provided with a water inlet 301 and a water outlet 302, and the first end of the water inlet 301 and the first end of the water outlet 302 both extend along the axial direction of the rotating shaft 30 itself; the upper end surface of the disc 40 is fixedly connected to the inner wall 101 of the noodle barrel 10, and the rotating shaft 30 is fixedly connected to the disc 40, the lower end surface or side surface of the disc 40 is connected to the outer wall 102 of the noodle barrel 10 to cover the first heat exchange cavity 20, and the disc 40 is provided with a water inlet through-hole 401 along its own axial direction, which is spaced apart from the water inlet through-hole 401. The water outlet through-hole 402 is connected to the water inlet through-hole 401 and the second end of the water inlet channel 301, and the water outlet through-hole 402 is connected to the second end of the water outlet channel 302. The upper end surface of the disk body 40 is recessed to form a water inlet groove 403 and a water outlet groove 404. One end of the water inlet groove 403 is connected to the water inlet through-hole 401, and the other end of the water inlet groove 403 passes through the side wall of the disk body 40 and is connected to the first heat exchange cavity 20; one end of the water outlet groove 404 is connected to the water outlet through-hole 402, and the other end of the water outlet groove 404 passes through the side wall of the disk body 40 and is connected to the first heat exchange cavity 20; the heat exchange pipe 50 is laid on the water inlet groove 403, the first end of the heat exchange pipe 50 is connected to the water inlet through-hole 401, and the second end of the heat exchange pipe 50 is connected to the first heat exchange cavity 20.

[0034] On the basis of the above structure, by setting the disk body 40 and the heat exchange pipe 50, the heat exchange pipe 50 is pre-buried in the water inlet tank 403 to avoid water from flowing into and out of the water, thereby ensuring a constant temperature cooling effect.

[0035] Preferably, the first end of the heat exchange pipe 50 is sealedly connected to the water inlet through hole 401, which can effectively prevent water from flowing into and out of the water.

[0036] In this embodiment, the bottom wall of the inner wall 101 of the noodle bucket 10 is fixedly connected to the upper end surface of the tray 40. A dough kneading water supply hole 103 is formed on the bottom wall of the inner wall 101 of the noodle bucket 10. The dough kneading water supply hole 103 is connected to the water outlet 404. This allows water in the water outlet 404 to enter the noodle bucket 10 through the dough kneading water supply hole 103, ensuring that the temperature of the dough kneading water is the same as the internal temperature of the noodle vat, further improving the temperature control effect.

[0037] In this embodiment, the first heat exchange cavity 20 surrounds the entire circumference of the noodle barrel 10 and is enclosed by at least the bottom wall and side walls of the inner wall 101 of the noodle barrel 10 and the bottom wall and side walls of the outer wall 102 of the noodle barrel 10 .

[0038] In this embodiment, the constant temperature noodle making machine further includes a partition 60 disposed within the first heat exchange cavity 20. The partition 60 is circumferentially arranged around the inner wall 101 of the noodle barrel 10 and cooperates with the inner wall 101 of the noodle barrel 10 to form a second heat exchange cavity 70. A first end of the partition 60 is connected to the lower end surface or side surface of the tray 40 to cover the second heat exchange cavity 70. The other end of the water outlet trough 404 extends through the side wall of the tray 40 and communicates with the second heat exchange cavity 70. Thus, by disposing the second heat exchange cavity 70 within the first heat exchange cavity 20, cooling water flowing out of the water outlet trough 404 can enter the second heat exchange cavity 70 to cool the dough within the noodle barrel 10. Since the volume of the second heat exchange cavity 70 is smaller than that of the first heat exchange cavity 20, the amount of cooling water used can be reduced.

[0039] In this embodiment, the second end of the partition 60 is spaced apart from the inner wall 101 of the noodle barrel 10 , thereby facilitating the installation of the partition 60 .

[0040] In other embodiments, the second end of the partition 60 is connected to the inner wall 101 of the noodle barrel 10 , that is, both ends of the partition 60 are fixed to the inner wall 101 of the noodle barrel 10 , thereby improving the fixing effect of the partition 60 .

[0041] In this embodiment, the second end of the partition 60 is bent toward the inner wall 101 of the noodle bucket 10 to form an upper edge 601. This upper edge 601 is spaced apart from the inner wall 101 of the noodle bucket 10. In practice, a small gap is formed between the upper edge 601 and the inner wall 101 of the noodle bucket 10. By bending the upper edge 601 at the second end of the partition 60, the top opening of the second heat exchange chamber 70 is shielded, preventing cooling water from splashing into the first heat exchange chamber 20.

[0042] Preferably, the second end of the partition 60 is bent 90° toward the inner wall 101 of the noodle bucket 10 to form an upper edge 601, so that the upper edge 601 is parallel to the bottom wall, which can improve the shielding efficiency. Of course, the upper edge 601 can also be an inclined upper edge 601 formed by bending the second end of the partition 60 upward or downward relative to the bottom wall to facilitate the manufacture of the partition 60.

[0043] In other embodiments, the upper edge 601 is connected to the inner wall 101 of the noodle barrel 10, so that both ends of the partition 60 are fixed on the inner wall 101 of the noodle barrel 10, thereby improving the fixing effect of the partition 60 and sealing the second heat exchange cavity 70.

[0044] In another embodiment, the second end of the partition 60 is connected to the outer wall 102 of the noodle barrel 10 , thereby increasing the diversity of installation methods of the partition 60 .

[0045] In this embodiment, the first end of the outer wall 102 of the noodle bucket 10 is connected to the side of the tray 40, and the second end of the outer wall 102 of the noodle bucket 10 is inclined toward the inner wall 101 of the noodle bucket 10, forming a beveled edge 104. The beveled edge 104 is separated from the inner wall 101 of the noodle bucket 10. In specific implementation, the beveled edge 104 is formed by bending the second end of the outer wall 102 of the noodle bucket 10 upward relative to the bottom wall. The beveled edge 104 is separated from the inner wall 101 of the noodle bucket 10 by a small gap. While facilitating the fixing of the outer wall 102 and improving heat dissipation efficiency, the beveled edge 104 also shields the top opening of the first heat exchange chamber 20, thereby reducing the ingress of external dust and the like into the first heat exchange chamber 20.

[0046] In other embodiments, the first end of the outer wall 102 of the noodle bucket 10 is connected to the lower end surface of the tray 40, and the oblique edge 104 is connected to the inner wall 101 of the noodle bucket 10. In this way, the fixing effect of the outer wall 102 of the noodle bucket 10 is improved, and the first heat exchange cavity 20 is sealed.

[0047] In this embodiment, the water inlet hole 401 and the water outlet hole 402 are symmetrical about the axis of the disk body 40. This is beneficial for distributing the routes of the water inlet groove 403 and the water outlet groove 404, and makes the rotation of the disk body 40 more in line with dynamic balance requirements.

[0048] In this embodiment, the water inlet trough 403 and the water outlet trough 404 are symmetrical about the axis of the disk body 40. This prevents the water inlet trough 403 and the water outlet trough 404 from intersecting each other, further ensuring that the disk body 40 rotates in a more balanced manner. Furthermore, this arrangement ensures that the ports of the water inlet trough 403 and the water outlet trough 404 are positioned opposite each other. This means that cooling water enters the second heat exchange cavity 70 from the water inlet trough 403 and circulates a certain distance before exiting through the water outlet trough 404, thereby ensuring sufficient cooling effect of the cooling water.

[0049] In this embodiment, the water inlet trough 403 includes several water inlet arc sections 405 and several water inlet connecting sections 406. The ends of adjacent water inlet arc sections 405 are connected by the water inlet connecting sections 406. The radii of the several water inlet arc sections 405 gradually increase from the inside to the outside along the radial direction of the disk body 40. The water outlet trough 404 includes several water outlet arc sections 407 and several water outlet connecting sections 408. The ends of adjacent water outlet arc sections 407 are connected by the water outlet connecting sections 408. The radii of the several water outlet arc sections 407 gradually increase from the inside to the outside along the radial direction of the disk body 40. This further improves the cooling effect of the cooling water.

[0050] In this embodiment, both the water inlet connecting section 406 and the water outlet connecting section 408 are configured as arcuate sections. The water inlet connecting section 406 extends radially along the disk body 40, while the water outlet connecting section 408 extends radially along the disk body 40. The water inlet connecting section 406 at the outermost edge of the disk body 40 extends radially from the inside outward through the sidewall of the disk body 40. The water outlet connecting section 408 at the outermost edge of the disk body 40 extends radially from the inside outward through the sidewall of the disk body 40. The arcuate shape of the water inlet connecting section 406 facilitates the installation of the heat exchange pipe 50, ensuring a closer fit between the heat exchange pipe 50 and the wall of the water inlet trough 403. Furthermore, this configuration not only facilitates the processing and manufacturing of the disk body 40, but also allows the water inlet trough 403 and the water outlet trough 404 to occupy more area of ​​the disk body 40, ensuring that cooling water flows through more parts of the disk body 40. In other embodiments, the water inlet connecting section 406 is set as an arc section and the water outlet connecting section 408 is set as a straight section, or both the water inlet connecting section 406 and the water outlet connecting section 408 are set as straight sections, thereby increasing the diversity of the structural settings of the water inlet connecting section 406 and the water outlet connecting section 408.

[0051] In this embodiment, the constant temperature noodle machine also includes a water inlet pipe and a water outlet pipe. One end of the water inlet pipe is connected to the first end of the water inlet channel 301, and one end of the water outlet pipe is connected to the first end of the water outlet channel 302. The other ends of the water inlet pipe and the water outlet pipe are respectively connected to the output end and the input end of the refrigerator. Thus, the cooling water can be input into the disk body 40 through the rotating shaft 30 to effectively cool the dough in the noodle barrel 10.

[0052] In this embodiment, the constant temperature noodle making machine further includes a driving device 80, which is used to drive the rotating shaft 30 to rotate so as to drive the noodle barrel 10 to rotate synchronously, thereby improving the noodle kneading efficiency.

[0053] Preferably, the drive device 80 includes a motor 801, a driving wheel connected to the motor 801, and a driven wheel 802 connected to the driving wheel. The driven wheel 802 is fixedly sleeved on the rotating shaft 30. The driving wheel can be a gear, sprocket, or other rotating element, as long as it can ensure that the rotating shaft 30 is driven, thereby ensuring that the dough bucket 10 can rotate. The rotation of the dough bucket 10 is conducive to improving dough kneading efficiency. In other words, in the present invention, the rotating shaft 30 does not necessarily need to be able to rotate; the key point is that it can achieve a constant temperature function.

[0054] In addition, the constant temperature noodle making machine further includes a machine base 90 , and the rotating shaft 30 is rotatably mounted on the machine base 90 , thereby achieving the installation and fixation of the rotating shaft 30 , which is beneficial to the rotation of the rotating shaft 30 .

[0055] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
