Technical Field
[0001] This utility model relates to the field of pastry processing equipment technology, and in particular to a fermentation pastry proofing box. Background Technology
[0002] Currently, proofing boxes are commonly used in pastry production to proof fermented dough. These boxes typically have support plates on both sides to hold proofing trays. Traditionally, proofing trays are simply slid in or pulled out of the support plates when placed or removed, resulting in significant frictional resistance between the trays and the plates. Over time, this not only makes operation laborious but also easily causes wear and tear on the trays and support plates, reducing their lifespan. Furthermore, due to the lack of a positioning structure, the trays may shift during proofing, affecting the proofing effect. Therefore, there is an urgent need for a fermentation box for pastries that can reduce frictional wear between the trays and support plates, improve ease of operation, and enhance equipment durability. Utility Model Content
[0003] The purpose of this invention is to provide a fermentation box for pastries that can reduce friction and wear between the fermentation tray and the support plate, ensuring the service life of the equipment. At the same time, it can position the fermentation tray placed on the support plate to ensure the stability of the pastries during fermentation and ensure the fermentation effect.
[0004] The present invention adopts the following technical solution:
[0005] A fermentation box for pastries includes support plates spaced apart on the inner walls of both sides of the box. A proofing tray is movably mounted on the support plates, and rollers are rotatably mounted on both sides of the proofing tray. The proofing tray is movably positioned on the support plates via the rollers. The support plates have positioning grooves, and when the proofing tray is placed on the support plates, the rollers are located in the positioning grooves.

[0021] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:
[0022] like Figures 1 to 5As shown, the fermentation box for pastries described in this utility model includes support plates 2 spaced apart on the inner walls of both sides of the fermentation box 1. Multiple sets of support plates are spaced apart along the height direction of the fermentation box 1. Fermentation trays 3 are movably mounted on two support plates 2 in each set. Rollers 4 are rotatably mounted on both sides of the fermentation trays 3. The fermentation trays 3 are movably placed on the support plates 2 by the rollers 4, which facilitates the placement and removal of the fermentation trays 3 on the support plates 2 and reduces wear between the fermentation trays 3 and the support plates 2. In addition, the support plates 2 have positioning grooves 5. When the fermentation trays 3 are placed on the support plates 2, the rollers 4 are located in the positioning grooves 5. The positioning grooves 5 position the rollers 4, which can ensure the stability of the fermentation trays 3 during operation.
[0023] Each side of the proofing tray 3 has two rollers 4 rotatably mounted along its length to provide stable support. Preferably, the two rollers 4 on each side of the proofing tray 3 are at different distances from the side wall of the proofing tray 3; the positioning grooves 5 on the support plate 2 are positioned corresponding to the positions of the rollers 4. The arrangement of the two rollers 4 on each side of the proofing tray 3 one in front of the other relative to the side wall of the proofing tray 3, and the arrangement of the two positioning grooves 5 on the support plate 2 one in front of the other along the width of the support plate 2, ensures that when the proofing tray 3 moves onto the support plate 2, the roller 4 located on the inner side of the proofing tray 3 avoids the position of the positioning groove 5 on the front side, thus enabling the proofing tray 3 to be smoothly placed and removed from the support plate 2.
[0024] In this embodiment, the length of the positioning groove is less than the diameter of the roller 4, which not only limits the movement of the roller 4 but also reduces the area of the roller 4 entering the positioning groove, facilitating the removal of the proofing tray 3. Furthermore, a support groove 6 is provided at the top of the proofing tray 3 corresponding to the position of the roller 4. The support groove 6 allows for the stacking of two proofing trays 3 when pastries are placed in them, by placing the roller 4 within the support groove 6, thus reducing the amount of horizontal space occupied. The length of the support groove 6 is less than the diameter of the roller 4 to ensure sufficient spacing between adjacent proofing trays 3, providing adequate storage space for the pastries.
[0025] Furthermore, each roller 4 can be adjusted along the height of the proofing tray 3 to adjust the height of the proofing tray 3 relative to the support plate 2 according to different needs, thereby adjusting the spacing between two adjacent proofing trays 3. This embodiment satisfies the requirement of placing pastries of different shapes and sizes in two adjacent proofing trays 3. In this case, the support plate 2 can be fully utilized, i.e., as many proofing trays 3 as possible can be placed, avoiding the situation in the prior art where proofing trays 3 need to be placed at intervals on the support plate 2 to avoid interference between the upper and lower layers of pastries. It is worth noting that this embodiment is only applicable to the prior art. During the procedure, the pastries in the upper proofing tray 3 are smaller in size, while those in the lower proofing tray 3 are larger. Placing the proofing trays 3 directly on the two adjacent support plates 2 with a small gap would cause interference, while placing them with a support plate 2 between them would result in too large a gap. By finely adjusting the height of the rollers 4, the height of the upper proofing tray 3 is moved upward relative to the height of the lower proofing tray 3. This allows for the placement of slightly larger pastries in the lower proofing tray 3, making full use of the space inside the fermentation box and avoiding the waste of internal space in the fermentation box 1 caused by arranging the proofing trays 3 at intervals on the support plates 2.
[0026] Specifically, the roller 4 is rotatably mounted on the L-shaped shaft 7, and the proofing tray 3 is equipped with a buffer sleeve 8. The buffer sleeve 8 is a sleeve structure that runs vertically through the shaft. The vertical section of the shaft 7 moves out of the buffer sleeve 8 and is elastically positioned at the top with a positioning toothed plate 9. Figure 4 As shown, a support block 10 is provided at the top of the rotating shaft 7. A receiving cavity 11 is formed within the support block 10. A positioning toothed plate 9 is connected to the receiving cavity 11 via a second spring 12. A positioning toothed groove 13 is formed on the side wall of the proofing box 1. The positioning toothed plate 9 engages with the positioning toothed groove 13. One end of the positioning toothed plate 9, away from the positioning toothed groove 13, extends out of the receiving cavity 11. When adjusting the roller 4, the operator pulls the positioning toothed plate 9 along its axial direction to disengage it from the positioning toothed groove 13, thus adjusting the height of the roller 4. Furthermore, the rotating shaft 7 is elastically positioned within a buffer sleeve 8 to assist in the reset of the roller 4. Specifically, a first spring 14 is sleeved on the rotating shaft 7. The bottom of the first spring 14 is fixedly connected to the inner bottom wall of the buffer sleeve 8, and the top of the first spring 14 is fixedly connected to a limiting plate on the rotating shaft 7.
[0027] This invention, through the installation of rollers 4, replaces the sliding contact between the proofing tray 3 and the support plate 2 with a rolling contact, which not only improves the convenience of placing and removing the proofing tray 3, but also greatly reduces the friction and wear between the proofing tray 3 and the support plate 2, ensuring the service life of the equipment components and improving the ease of operation. By setting a positioning groove 5 on the support plate 2, when the proofing tray 3 is placed on the support plate 2, the rollers 4 are located in the positioning groove 5, which can ensure the stability of the proofing tray 3. The structure is simple, easy to operate and use, and highly practical.
