Description

Technical Field

[0001] The present invention relates to the technical field of bread processing, and particularly to a fabric fermentation device and method for bread processing. Background Technique

[0002] Fermentation refers to the process in which people rely on the life activities of microorganisms under aerobic or anaerobic conditions to prepare the microorganisms themselves, or directly metabolites or secondary metabolites. In the process of bread processing, fermentation is an essential link, usually carried out in a fermentation box. The fabric is placed on a stainless steel bracket and then sent into the fermentation box.

[0003] However, in this process, since the brackets of traditional fermentation boxes are mostly fixed multi-layer structures, and the racks for placing trays inside the fermentation box are stacked layer by layer. Therefore, when placing the fabric at the highest position, climbing is required. During the climbing or placing process, it is very easy for the stainless steel bracket to tilt. On the one hand, it will increase the operation difficulty and reduce the operation efficiency. On the other hand, it may cause the fabric to move or even fall, resulting in low operation safety.

Two symmetrically distributed openings are formed at one end of each of the first tray racks, and the connecting blocks are movably arranged in the openings. Bayonets are penetrated through the walls of the plurality of connecting blocks, and clamping posts are inserted into the plurality of bayonets. The clamping posts are driven to move horizontally by the rotating member.

[0010] In a preferred embodiment: the rotating member includes a cavity, a rotating motor, a ball screw and a nut sleeve.

One end of the clamping post away from the connecting block is fixedly connected to the nut sleeve.

[0011] In a preferred embodiment: The installation component includes a first storage cavity, a fixing plate, fastening bolts, and threaded grooves. First storage cavities are formed on the upper end walls of the first tray rack and the second tray rack. The tray is slidably disposed in the first storage cavity.

Fastening bolts are threadedly connected in the threaded grooves. Second storage cavities are formed at the lower ends of the first tray rack and the second tray rack. Baffles are fixedly connected to the upper ends of two of the second tray racks and two of the first tray racks on both sides.

[0012] In a preferred embodiment: The triggering component includes a resisting post, a third storage cavity, a sliding plate, a gravity sensor, and a resetting member.

The plurality of laser rangefinders are staggered in the vertical plane. An induction plate is installed in the first tray rack at a position corresponding to the laser rangefinder. The laser rangefinder is electrically connected to the rotating motor.

[0014] A method for using a bread processing fabric fermentation device is as follows: S1. Install the trays on the first tray rack and the second tray rack respectively through the installation component, and then evenly place the weighed bread fabric in the trays. S2. After placing, start the driving member. The driving member drives the sprocket to rotate through the transmission member, and then drives the chain to rotate through the sprocket. The chain drives the first tray rack to slide in the fermentation chamber through the connecting block, and adjust the height of the first tray rack according to actual needs to move the first tray rack to a suitable position. S3. Close the fermentation box and perform the fermentation operation on the bread dough. After fermentation is completed, open the fermentation box. Similarly, start the driving member to reverse, causing the three upper first tray racks to move downward. When the lowermost first tray rack moves above the second tray rack and continues to move downward, the abutting column abuts against the sliding plate and slides upward until the gravity sensor contacts the inner wall of the upper end of the third storage cavity. The value of the gravity sensor changes, causing the rotating motor to rotate in the reverse direction. The ball screw rotates synchronously with the rotation direction of the rotating motor, and the two screw sleeves approach each other, causing the clamping column to disengage from the bayonet. At this time, the lowermost first tray rack is placed on the second tray rack. And so on, the three first tray racks are stacked in sequence, reducing the height of the three first tray racks. Then take out the fermented dough.

[0015] Through the transmission system composed of the adjustment components, the present invention can accurately and stably drive the chain to rotate, thereby driving the connecting block and the first tray rack to slide in the fermentation box. The operator does not need to climb to a high place to place the dough. Just start the driving motor to flexibly adjust the height of the first tray rack according to the needs. For example, when placing the dough, the first tray rack can be adjusted to a suitable lower position, which is convenient for the operator to easily place the dough on the tray, greatly reducing the operation difficulty. During the placement process, since the first tray rack is in a lower and stable position, the risk of the bracket tilting caused by climbing in the traditional method is avoided, effectively preventing the dough from moving or falling, and significantly improving the operation efficiency and safety. Through structures such as the abutting column, sliding plate, gravity sensor, and return spring, after fermentation is completed, multiple first tray racks are automatically placed and stacked. This automated operation does not require manual disassembly and stacking of the tray racks, saving labor and time costs. When the first tray rack needs to be reset later, the cooperation of the laser rangefinder and the induction plate can accurately control the first tray rack to return to the initial position, ensuring the convenience and accuracy of the device operation.

[0016] The first storage cavity opened on the first tray rack and the second tray rack of the present invention provides an accurate installation and positioning space for the tray. The tray is firmly installed on the first tray rack and the second tray rack through the cooperation of the fixing plate, threaded groove, and fastening bolt, and also facilitates the disassembly of the tray, which is convenient for the regular cleaning of the tray. The casters installed at the bottom of the fermentation box enable the entire device to have flexible mobility. In the bread processing workshop, according to the adjustment of the production layout, equipment maintenance, or different production requirements, the fermentation box can be easily pushed to the designated position without the aid of other handling equipment, greatly improving the convenience of using the device.

The chain (5) drives the first tray rack (3) to slide in the fermentation box (1) through the connecting block (6), and adjusts the height of the first tray rack (3) according to actual needs to move the first tray rack (3) to a suitable position; S3, Close the fermentation box (1) and perform the fermentation operation of the bread flour. After the fermentation is completed, open the fermentation box (1). Similarly, start the driving member (4) to reverse, so that the upper three first tray racks (3) move downward. When the lowermost first tray rack (3) moves above the second tray rack (7), as the first tray rack (3) continues to move downward, the abutting post (27) abuts against the slide plate (29) and slides upward until the gravity sensor (30) contacts the inner wall of the upper end of the third storage cavity (28), the value of the gravity sensor (30) changes, causing the rotation motor (19) to rotate in the reverse direction, and the ball screw (20) rotates synchronously with the rotation direction of the rotation motor (19), and the two screw sleeves (21) approach each other, so that the clamping post (17) disengages from the bayonet (16). At this time, the lowermost first tray rack (3) is placed on the second tray rack (7). By analogy, the three first tray racks (3) are stacked in sequence to reduce the height of the three first tray racks (3), and then the fermented flour is taken out.
