Specific Embodiment

[0028] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the specific embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0029] As Figures 1-9 shown, the present invention discloses a bread production proofing box, which includes a box body 1 in a vertical cylindrical structure and a carrier 2 vertically installed inside the box body 1; a plurality of support feet 11 are annularly and arrayedly installed at the bottom of the box body 1; the carrier 2 includes a rotating shaft 21 vertically rotatably (through a sealed bearing) installed at the axis position of the box body 1 and a plurality of carrier fan blades 22 connected to the circumferential side surface of the rotating shaft 21. The carrier fan blades 22 are in a spiral fan shape (the fan angle is 30-90 degrees), and a plurality of carrier fan blades 22 are spirally distributed along the circumferential side surface of the rotating shaft 21. There is a certain distance between the outer edge of the carrier fan blade 22 and the circumferential side wall of the box body 1; a plurality of electric heating devices 6 are circumferentially and arrayedly arranged at the inner bottom of the box body 1, and a humidifying pipe 42 is fixedly installed on the circumferential inner wall of the box body 1. A plurality of spray holes are opened on the humidifying pipe 42. A humidifying device 4 communicated with the humidifying pipe 42 and a motor 3 drivingly connected to the rotating shaft 21 are fixedly installed outside (at the top) of the box body 1; an arc-shaped box door 12 (vertically narrow) is rotatably installed on the side of the box body 1 through a hinge, and a box door handle 13 is connected to the box door 12; this bread production proofing box further includes a plurality of trays 8 that can be placed on the carrier fan blades 22 and used to carry bread embryos.

[0030] In use, place the bread embryo on the tray 8, place the tray 8 on the corresponding bearing fan blade 22, and close the box door 12; start the electric heating device 6 and the humidifying device 4, and control the motor 3 to drive the bearing frame 2 to rotate, so that the bearing fan blades 22 on the bearing frame 2 rotate slowly. The air in the middle (within the coverage of the bearing fan blades 22) flows downward under the flapping of the bearing fan blades 22, is evenly heated by a number of electric heating devices 6 arranged in an annular array at the bottom, and flows upward from the gap between the bearing fan blades 22 and the circumferential side wall of the box body 1 (the non-covered area of the bearing fan blades 22), and at the same time drives the mist ejected from the humidifying pipe 42 (spray holes) to flow from the top to the middle inside the box body 1, thereby forming a stable and uniform air circulation, making the temperature and humidity distribution inside the box body 1 uniform, avoiding local overheating or overcooling, so that the bread embryos rotating with the bearing fan blades 22 have better fermentation consistency, improving the fermentation quality, and making the temperature and humidity control more accurate under the condition of uniform temperature and humidity distribution. In addition, open the box door 12 through the box door handle 13, and manually rotate the bearing frame 2 to put in and take out the bread embryo (tray 8), making the operation more flexible and convenient, reducing the labor intensity, and effectively reducing the probability of the bread embryo being bumped and damaged, improving the appearance of bread production.

[0031] Among them, a number of temperature and humidity sensors 7 are arranged at intervals on the circumferential side surface of the rotating shaft 21; a control device 5 is fixedly installed at the bottom of the box body 1; the control device 5 is respectively connected to the temperature and humidity sensors 7, the motor 3, the humidifying device 4 and the electric heating device 6 in a signal connection. Through a number of temperature and humidity sensors 7, the temperature and humidity information at different positions and different heights inside the box body 1 can be monitored in real time. Compared with the traditional monitoring method of single-point or a small number of points in the proofing box, this layout can obtain more comprehensive and accurate temperature and humidity data inside the box. The control device 5 can timely and accurately adjust the rotation speed of the motor 3 (thereby adjusting the rotation speed of the bearing frame 2, affecting the uniformity of the bread embryo being heated and wetted, and controlling the adjustment speed), the humidifying amount of the humidifying device 4 and the heating power of the electric heating device 6 according to the accurate data fed back by the temperature and humidity sensors 7, ensuring the consistency and quality of bread production.

[0032] Such as Figure 4As shown, the middle part of the inner bottom surface of the box body 1 is smoothly convex, and there are transition rounded corners between the inner bottom surface of the box body 1 and its side surface; there are transition rounded corners between the inner top surface of the box body 1 and its side surface. The right angles and sharp corners on the inner wall of the box body 1 are reduced, making the hot air and moisture flow more smoothly inside the box body 1, and it is not easy to generate air flow dead corners. Whether it is the hot air rising from the bottom electric heating device 6 or the moisture sprayed from the humidifying pipe 42 circulating and diffusing inside the box body 1, it can be more evenly distributed in all corners of the box body 1, further optimizing the uniformity of temperature and humidity inside the box body 1, helping the bread embryo to ferment more evenly, and improving the consistency and quality of bread production. In addition, the design of the transition rounded corners and the smoothly convex inner bottom surface in the middle effectively reduces the sanitary dead corners, avoiding the situation where impurities such as bread crumbs and water vapor accumulate in the corners and are difficult to clean, providing a cleaner environment for the fermentation of the bread embryo, and indirectly ensuring the quality of the bread.

[0033] Furthermore, a water hole with controllable opening and closing is provided at the lowest position of the bottom surface of the box body 1, which can conveniently discharge the accumulated water at the bottom.

[0034] As Figure 3 、 5 shown, the electric heating device 6 includes a heating body 61 in a U-shape, and the horizontal section direction of the heating body 61 is perpendicular to the radial direction of the box body 1; when the air flowing downward from the middle diffuses outward from the bottom of the box body 1, it flows through the U-shaped heating body 61, so as to achieve sufficient and uniform heating.

[0035] Furthermore, a number of heating fins 62 perpendicular to it are arranged at intervals along the length direction on the horizontal section of the heating body 61. By increasing the contact area with the air through the heating fins 62, the heating efficiency is improved, the heating-up speed is accelerated, and accurate and stable control of the temperature is achieved.

[0036] Among them, the electric heating device 6 adopts a PTC ceramic heating structure, with constant temperature characteristics to avoid overheating, the energy consumption ratio is 20%-30% lower than that of the electric heating tube, there is no risk of dry burning, energy-saving and safe; the heating temperature uniformity is good (error ≤ ±0.5°C).

[0037] Among them, as Figures 3-4 shown, the humidifying pipe 42 is horizontally arranged in a ring on the upper part of the circumferential inner wall of the box body 1, and it is connected to the humidifying device 4 through a connecting pipe 41. The moisture generated by the humidifying device 4 can evenly pass through the annular humidifying pipe 42 and spray out from the spray holes on it. Since the humidifying pipe 42 is surrounded by the upper part of the circumferential inner wall of the box body 1, the sprayed moisture can, under the action of air flow, be more evenly diffused downward from the middle to the periphery of the bread embryo and spread to the entire space of the box body 1, effectively improving the uniformity of the humidity distribution inside the box body 1, avoiding local humidity being too high or too low, and thus ensuring that the bread embryo is in an environment with suitable and uniform humidity during the fermentation process.

[0038] Further, the spray holes on the humidifying pipe 42 are inclined upward and inward, and the included angle between the spray holes and the side wall of the box body 1 is 30 degrees. This causes the moisture ejected from the spray holes to be sprayed upward and toward the middle, and along with the air flowing toward the middle, it diffuses throughout the box body 1 under the action of gravity and the flapping of the bearing fan blades 22. This enables the moisture to have a wider initial diffusion range in the upper part of the box body 1, avoiding the concentration of moisture in local areas and further optimizing the uniform distribution of humidity in the box body 1.

[0039] Among them, the humidifying device 4 uses ultrasonic humidification. It uses ultrasonic high-frequency oscillation to atomize water into micron-sized particles, which are blown into the box body 1 by a blower. Ultrasonic humidification is more delicate (the diameter of the mist particles ≤ 5μm), the humidity can reach 85% - 95%, and the uniformity is good. Moreover, the control is precise, and it can be automatically started and stopped in cooperation with the temperature and humidity sensor 7 (controlled by the control device 5) to avoid over-humidification.

[0040] As shown in FIGS. 6 - 7, an upward side edge 222 is provided on the outer edge of the bearing fan blade 22, an upward lower edge 221 is provided on the lower radial edge, and an inclined guide plate 223 is folded upward on the higher radial edge. The included angle between the guide plate 223 and the horizontal plane is 15 - 30 degrees and is greater than the self-spiral inclination angle of the bearing fan blade 22. The side edge 222, the lower edge 221, and the guide plate 223 can effectively limit the tray 8, preventing it from displacing or slipping, ensuring the stability of the bread embryo during the proofing process, and the guide plate 223 with a larger inclination angle can effectively increase the downward flow of the air current, contributing to the rapid circulation of the air in the box body 1.

[0041] Further, as Figures 8-9 shown, the tray 8 includes a tray bottom plate 81 adapted to the bearing fan blade 22, and a tray edge 82 is folded upward along the edge of the tray bottom plate 81; the inner tray edge 82 is in an arc shape adapted to the rotating shaft 21. The tray 8 can support the bread embryo, the tray edge 82 can limit the bread embryo, and through the fitting of the tray bottom plate 81 with the bearing fan blade 22, the fitting of the inner tray edge 82 with the rotating shaft 21, and the limitation of the tray 8 by the side edge 222, the lower edge 221, etc., the accuracy, stability, and reliability of the placement of the tray 8 are realized.

[0042] Furthermore, a front handle 83 of the tray is connected to the outer side of the outer tray edge protector 82 (higher than the height of the side edge 222); a rear handle 84 of the tray in a T shape is connected to the upper side of the inner tray edge protector 82. The horizontal section of the rear handle 84 of the tray is in an arc shape adapted to the rotating shaft 21, and positioning columns 85 are arranged on the inner sides of both ends of the horizontal section of the rear handle 84 of the tray. Corresponding positions on the side wall of the rotating shaft 21 are provided with clamping grooves (vertically long strip-shaped) that can be clamped and matched with the positioning columns 85. The settings of the front handle 83 and the rear handle 84 of the tray facilitate the staff to grip. Whether taking the tray 8 out of the bearing fan blade 22 or placing the tray 8 on the bearing fan blade 22, it is more labor-saving, convenient, stable and reliable, greatly reducing the labor intensity of the staff; when the tray 8 is placed on the bearing fan blade 22, through the clamping and matching limit of the positioning column 85 and the clamping groove on the rotating shaft 21, and through the adaptation and fitting of the horizontal section of the rear handle 84 of the tray with the rotating shaft 21, the tray 8 can be accurately positioned and reliably placed on the bearing fan blade 22, ensuring that the tray 8 will not shake randomly during the rotation of the bearing rack 2, thereby providing a stable placement environment for the bread embryo, avoiding damage to the bread embryo caused by the shaking of the tray 8, ensuring that the bread embryo can ferment normally, and helping to improve the consistency and quality of bread production.

[0043] When this bread production proofing box is in use, the bread embryo is placed on the tray 8, the tray 8 is placed on the corresponding bearing fan blade 22, and the box door 12 is closed; the electric heating device 6 and the humidifying device 4 are started, and the motor 3 is controlled to drive the bearing rack 2 to rotate, so that the bearing fan blade 22 on the bearing rack 2 rotates slowly. The air in the middle (within the coverage of the bearing fan blade 22) flows downward under the flapping of the bearing fan blade 22, is evenly heated by a plurality of electric heating devices 6 arranged in a bottom annular array, and flows upward through the gap between the bearing fan blade 22 and the circumferential side wall of the box body 1 (the non-covered range of the bearing fan blade 22), and at the same time drives the mist sprayed by the humidifying pipe 42 to flow from the top to the middle in the box body 1, thereby forming a stable and uniform air circulation, making the temperature and humidity distribution in the box body 1 uniform, avoiding local overheating or overcooling, so that the bread embryo following the rotation of the bearing fan blade 22 has better fermentation consistency, improving the fermentation quality, and making the temperature and humidity control more accurate under the condition of uniform temperature and humidity distribution. In addition, by opening the box door 12 through the box door handle 13 and manually rotating the bearing rack 2, the bread embryo (tray 8) can be put in and taken out, making the operation more flexible and convenient, reducing the labor intensity, and effectively reducing the probability of the bread embryo being knocked and damaged, improving the appearance of bread production.
