Description

Technical Field

[0001] The present invention relates to the field of food processing equipment, and particularly to a pasta proofing device. Background Art

[0002] In the pasta making process, the proofing stage is one of the key steps determining the final quality of pasta. During the proofing process, in a suitable temperature and humidity environment, microorganisms such as yeast can fully ferment, causing the dough to expand and its texture to become soft, thereby enhancing the taste and flavor of the pasta. Currently, there are various types of pasta proofing equipment on the market. However, these devices generally have some problems that need to be solved urgently:

[0003] Problem of uneven temperature distribution. The air duct design of traditional proofing equipment is often not reasonable enough. Many devices use the method of directly blowing hot air downward by a top fan. Since hot air has the property of rising, it is difficult for the heat to be evenly distributed to the bottom area of the equipment during the heat transfer process. This makes the dough placed at the bottom unable to obtain the same proofing conditions as the upper dough, ultimately resulting in inconsistent proofing effects of the pasta. Some dough may be over-proofed while some are under-proofed, seriously affecting the overall quality of the pasta. For example, in a large proofing box used in some bakeries, the volume and softness of the bottom layer of bread are significantly inferior to those of the upper layer of bread, which is caused by uneven temperature.

[0004] Problem of humidity control. Some proofing equipment has defects in humidity control. On the one hand, some devices rely on external humidifying devices to maintain the humidity of the proofing environment. However, in actual operation, it is not easy to precisely control the humidity. If the humidity is adjusted improperly, problems such as cracking on the surface of the dough or stickiness on the surface of the dough and bacteria growth due to excessive humidity may occur. On the other hand, although some devices try to maintain the humidity of the dough itself by means of sealing, due to unreasonable structural design, they cannot effectively prevent the loss of humidity, causing the dough to gradually dry out during the proofing process, affecting the activity of yeast and the expansion effect of the dough.

[0005] In summary, the existing pasta proofing equipment has many deficiencies in temperature distribution and humidity control, and cannot meet the requirements of modern pasta making for high quality and high efficiency. Therefore, it is of great practical significance and market value to develop a new type of pasta proofing device that can solve the above problems. Summary of the Invention

[0036] The present invention will be introduced in detail and specifically below through specific embodiments to better understand the present invention. However, the following embodiments do not limit the protection scope of the present invention.

[0037] Embodiment 1

[0038] This embodiment discloses a pasta proofing device.

[0039] As Figures 1 to 3As shown in the figure, this embodiment includes a device main body 1, which is composed of a box body 2 and a heating and circulation system 3. The box body 2 serves as the outer shell of the device, playing a role in accommodating and protecting the internal components, and at the same time providing a relatively enclosed space for the proofing of pasta. The heating and circulation system 3 is the core part for realizing temperature control and hot air circulation, and can create suitable temperature conditions for the proofing of dough.

[0040] Ventilation duct 31: The ventilation duct 31 is arranged in the middle of the box body 2 and is the key to achieving uniform temperature distribution. The ventilation duct 31 includes an air inlet pipe 311, a horizontal pipe 312, and an air outlet pipe 313. The air inlet pipe 311 and the air outlet pipe 313 are arranged vertically, and the horizontal pipe 312 connects the bottom of the air inlet pipe 311 and the bottom of the air outlet pipe 313 to form a continuous hot air channel. There are hot air holes 34 on both sides of the ventilation duct 31, specifically including horizontal holes 341 and vertical holes 342. The horizontal holes 341 are arranged on both sides of the horizontal pipe 312, and the vertical holes 342 are arranged on both sides of the bottom of the air inlet pipe 311 and both sides of the bottom of the air outlet pipe 313. This layout enables hot air to be evenly blown into the interior of the box body 2 from multiple directions, ensuring that heat can be fully and evenly transferred to all corners of the box body 2, effectively solving the problem of uneven temperature distribution in traditional devices.

[0041] Heater 32: The heater 32 is arranged at the bottom of the ventilation duct 31, specifically fixed on the inner wall of the top of the horizontal pipe 312. There is a maintenance opening 314 at the bottom of the horizontal pipe 312, and the maintenance opening 314 is arranged below the heater 32. Such a design not only ensures that the heater 32 can effectively heat the air but also facilitates quick maintenance and replacement when the heater 32 fails, improving the maintainability of the device.

[0042] Fan 33: The fan 33 is arranged at the top of the box body 2, fixed to the bottom of the top plate 21. There is an air outlet 331 on the fan 33. There is a fixing hole 22 in the middle of the top plate 21, and a motor 11 is arranged on the fixing hole 22. The motor 11 is connected to the fan 33 to provide power for the fan 33. The function of the fan 33 is to blow the hot air generated by the heater 32 into the interior of the box body 2 through the ventilation duct 31 and promote the circulation of hot air in the box body 2, further enhancing the uniformity of temperature.

[0043] Components of the box body 2: The box body 2 includes multiple components such as a front panel, a rear panel 23, a top panel 21, side panels 28, a support frame 27, and a door panel 25. The front panel includes a door frame 24 and a door panel 25. The door panel 25 is arranged on the left and right sides of the door frame 24, and a handle 26 is provided on the door panel 25 to facilitate the operator to open and close the prover. The air inlet pipe 311 is fixed on the inner wall of the rear panel 23, and the air outlet pipe 313 is fixed on the inner wall of the door frame 24. The side panels 28 are arranged on the left and right sides of the box body 2. The side panels 28, the top panel 21, and the rear panel 23 are fixed on the support frame 27, and the door panel 25 is rotatably connected to the support frame 27. This structural design makes the box body 2 structurally stable and facilitates installation and use.

[0044] Other components: A fixing rod 35 is provided between the air inlet pipe 311 and the air outlet pipe 313. The fixing rod 35 is arranged below the fan 33 and plays a role in strengthening and stabilizing the ventilation duct 31, ensuring that the ventilation duct 31 does not shake or displace during operation. An electric control box 12 is provided on one of the side panels 28. The electric control box 12 is electrically connected to the heater 32 and the motor 11 and is used to control the working states of the heater 32 and the motor 11 to achieve precise adjustment of temperature and air volume and meet the needs of different pasta provers.

[0045] Specific usage method of this embodiment

[0046] Connect the power supply of the device, open the electric control box 12, and set appropriate parameters such as temperature and the rotation speed of the fan 33 according to the type and requirements of the pasta to be proved. For example, for proving steamed buns, generally set the temperature at 35 - 38 degrees Celsius and the rotation speed of the fan 33 at a moderate gear; for proving bread, the temperature may need to be set at 38 - 40 degrees Celsius, and the rotation speed of the fan 33 can be fine-tuned according to the actual situation. Place the pasta to be proved on the tray inside the prover, and pay attention not to overstack to ensure that the hot air can fully contact each dough. Close the door panel 25 to ensure good sealing of the box body 2.

[0047] Start the device, the heater 32 starts to work and heats the air in the ventilation duct 31. At the same time, the fan 33 starts to operate driven by the motor 11, and blows the heated hot air into the box body 2 through the ventilation duct 31. The hot air uniformly blows out from the hot air holes 34 of the ventilation duct 31, circulates in the box body 2, fully contacts the dough, provides a suitable temperature environment for the dough, promotes yeast fermentation, and realizes the proving of the dough. During the proving process, the operator can monitor the temperature and the operating state of the fan 33 in real time through the electric control box 12 and make fine adjustments according to the actual situation. For example, if it is found that the temperature is too high or too low, the power of the heater 32 can be appropriately adjusted; if it is found that the hot air circulation is uneven, the rotation speed of the fan 33 can be adjusted.

[0048] Regularly check the operating status of the equipment, including the heating effect of the heater 32, the operation of the fan 33, and whether the control function of the electric control box 12 is normal. Regularly clean the sundries in the ventilation duct 31 to prevent the hot air holes 34 from being blocked, which may affect the uniform distribution of hot air. Check the sealing performance of the box body 2 to ensure that heat and humidity will not be lost during the proofing process. For the heater 32, conduct a comprehensive inspection every once in a while (such as every six months). If a fault is found, it can be repaired or replaced through the maintenance port 314 at the bottom of the horizontal pipe 312. At the same time, check whether the connection parts of the motor 11 and the fan 33 are loose to ensure the safe and stable operation of the equipment.
