TECHNICAL FIELD

[0001] The present application relates to the technical field of food leavening equipment, in particular to a food leavening device with a circulating structure. BACKGROUND

[0002] The leavening of food snacks is a key link that determines the quality of finished products. During the leavening process, the yeast in the dough will use sugars for aerobic respiration to produce carbon dioxide gas. These gases are evenly distributed inside the dough, forming countless tiny air chambers, which promote the expansion and volume increase of the dough.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0043] Embodiment one

[0044] Referring to Figure 1 and Figure 2 , the application provides a technical solution: a dough fermentation device with a circulation structure, comprising a double-chamber fermentation box 1, a partition plate is fixed in the middle of the double-chamber fermentation box 1, heating wires 101 are installed on the inner wall surface of the back side of the double-chamber fermentation box 1, and clean water trays 102 are arranged on the bottom wall of the inner side of the double-chamber fermentation box 1; the heating wires 101 are connected with the two clean water trays 102 at the same time, the air inside the double-chamber fermentation box 1 and the clean water in the clean water trays 102 are heated by the heating wires 101, symmetrical air diffusers 103 are installed on the top of the double-chamber fermentation box 1, a split box door is movably connected to one side of the double-chamber fermentation box 1, and a control panel is arranged on the adjacent side of the double-chamber fermentation box 1 close to the split box door.

[0045] In this embodiment, the heating wires 101 are controlled by the control panel to reach a suitable temperature for fermenting dough, the air inside the double-chamber fermentation box 1 and the clean water in the clean water trays 102 are heated, the temperature and humidity inside the double-chamber fermentation box 1 can reach a sufficient level, and the temperature and humidity are monitored by the control panel, then the air diffusers 103 on the top of the double-chamber fermentation box 1 are started to guide the hot air inside the double-chamber fermentation box 1 outwards, so that the hot air can circulate and flow in the double-chamber fermentation box 1.

[0046] Since the split box door is arranged on one side of the double-chamber fermentation box 1, when one of the box doors is opened, dough can be taken out or put into one of the chambers of the double-chamber fermentation box 1, and the fermentation of dough can continue in the other chamber, so that the double-chamber fermentation box 1 can intermittently ferment dough with different putting-in times.

[0047] Referring to Figures 1-4 , a driving turntable 2 is rotatably connected in the partition plate in the middle of the double-chamber fermentation box 1, driven turntables 3 are symmetrically connected to the inner walls on both sides of the double-chamber fermentation box 1, a central shaft for synchronous rotation is fixed between the driving turntable 2 and the driven turntables 3, a speed reducer 202 is embedded in the bottom of the double-chamber fermentation box 1, a belt wheel 201 is connected to the output end of the speed reducer 202, and a belt 203 that simultaneously sleeves the driving turntable 2 and the belt wheel 201 is arranged in the partition plate in the middle of the double-chamber fermentation box 1.

[0048] In this embodiment, the speed reducer 202 is started to drive the belt wheel 201 to rotate, then the belt wheel 201 drives the driving turntable 2 to rotate in the partition plate in the middle of the double-chamber fermentation box 1 through the belt 203, and the driving turntable 2 rotating in the partition plate in the middle of the double-chamber fermentation box 1 drives the driven turntables 3 on both sides to rotate through the central shaft.

[0049] Referring to Figures 1-4 , Figure 7 and Figure 8Rotating rods 4 are movably connected to both sides of the active turntable 2 and one side of the driven turntable 3. A support mechanism 6 that rotates with the rotating rods 4 is set at an equal angle between the active turntable 2 and the driven turntable 3. The support mechanism 6, which rotates with the rotating rods 4, prevents the dough to be proofed from falling. The support mechanism 6 includes a hanging seat 601 that is connected to the rotating rod 4. A tray 602 for holding the dough is installed between two adjacent hanging seats 601 by screws. The hanging seat 601 consists of an inverted U-shaped hanging rod fixed to the rotating rod 4 and a fixed seat installed at the bottom of the inverted U-shaped hanging rod.

[0050] In this embodiment, when the active turntable 2 and the driven turntable 3 rotate together, the rotating rod 4, which is movably connected to the active turntable 2 and the driven turntable 3, will suspend the supporting mechanism 6 through the hanging seat 601. Due to the force of gravity, when the rotating rod 4 rotates with the active turntable 2 and the driven turntable 3 to different angle positions, the supporting mechanism 6 will always be in a suspended state through the rotating rod 4, and the opening of the tray 602 will always face upward, so that the dough to be proofed can be placed through the tray 602.

[0051] Please see Figures 1-3 , Figures 5-7 The tray 602 has equally spaced blocks 603 inside, and the tray 602 is divided into multiple non-stick chambers for holding dough by the equally spaced blocks 603. The two sides of the blocks 603 are designed with symmetrical bevels, which makes it more convenient to pick up and put down the dough.

[0052] In this embodiment, the tray 602 is divided into multiple non-sticky compartments for holding dough by the baffle 603. Therefore, the workers can place the dough in the multiple compartments of the tray 602 at intervals. When the dough is proofing, the baffle 603 can separate adjacent doughs as they expand in volume, preventing the two adjacent doughs from sticking together.

[0053] Please see Figures 5-9 The tray 602 is provided with a support component 604 for directly fitting and holding the dough. The support component 604 includes arc-shaped support strips 6041 that symmetrically run through both sides of the block 603.

[0054] An adjustment port 6031 is provided in the middle of the stop block 603. An elliptical support bar 6042 is slidably connected inside the adjustment port 6031. The arc-shaped support bar 6041 and the elliptical support bar 6042 are distributed in an arc shape. There are gaps between two adjacent arc-shaped support bars 6041, two adjacent elliptical support bars 6042, and between the arc-shaped support bar 6041 and the elliptical support bar 6042.

[0055] In the embodiment, since gaps are left between the two adjacent arc-shaped struts 6041, the two adjacent elliptical struts 6042, and the arc-shaped struts 6041 and the elliptical struts 6042, when the dough is placed in the cavities of the tray 602, the dough can be separated from the inner wall of the tray 602 by the arc-shaped struts 6041 and the elliptical struts 6042, so that the dough does not contact the inner wall of the tray 602, and the gaps can make the air flow between the arc-shaped struts 6041 and the elliptical struts 6042, so that the bottom wall of the dough can be in contact with the air. The adjusting openings 6031 are arranged in the middle of the stopper 603, so that the air between the bottoms of the adjacent cavities can flow, and the arc-shaped struts 6041 and the elliptical struts 6042 are arranged in an arc shape, so that the arc-shaped struts 6041 and the elliptical struts 6042 can prevent the dough from rolling and deviating when the dough is in contact with the arc-shaped struts 6041 and the elliptical struts 6042. The stopper 603 can be disassembled, so that the supporting assembly 604 can be disassembled and cleaned regularly.

[0056] Please refer to Figures 1-3 , Figures 5-9 , the surface of the tray 602 is equidistantly provided with air guide slits 6021 for air flow.

[0057] The bottom of the tray 602 is provided with a saucer 605, and the tray 602 and the saucer 605 are provided with V-shaped flow channels for air flow.

[0058] In the embodiment, when the hot air carrying water vapor flows in the double-cabin proofing box 1, the hot air can flow through the air guide slits 6021 on the surface of the tray 602, so that the hot air can flow below the arc-shaped struts 6041 and the elliptical struts 6042, and the hot air can also flow along the V-shaped flow channels between the tray 602 and the saucer 605. Therefore, the hot air can exchange and flow in the air guide slits 6021, the adjusting openings 6031, the arc-shaped struts 6041, the elliptical struts 6042, and the V-shaped flow channels, so that the supporting mechanism 6 for supporting the dough can make the dough and the air circulate efficiently.

[0059] The saucer 605 at the bottom of the tray 602 can not only make the supporting mechanism 6 suspended and placed more stably by increasing the weight, but also can hold the falling flour and water droplets from the air guide slits 6021, so that the dough rotating on the upper side does not affect the dough on the lower side.

[0060] Please refer to Figure 9 and Figure 10 , the inner ends of the two ends of the elliptical struts 6042 are inserted with elastic eccentric columns 6043, and the eccentric shafts of the elastic eccentric columns 6043 are movably connected to the inner walls of the tray 602.

[0061] In the embodiment, since the cross section of the elliptical strut 6042 is in the shape of a hollow ellipse, the elliptical strut 6042 has a sufficient supporting capacity, and when the dough is concentratedly placed at a local position of the elliptical strut 6042, the elliptical strut 6042 will not be elastically deformed;

[0062] Since the elliptical strut 6042 is slidingly connected in the adjusting opening 6031 of the stopper 603, when the elliptical strut 6042 slides along the adjusting opening 6031, the elliptical strut 6042 will drive the elastic eccentric column 6043 to overcome the gravity and be deflected and lifted, at this time, the gravity generated by the elastic eccentric column 6043 itself will pull the elliptical strut 6042 to reset, so as to ensure that the rotatable elastic eccentric column 6043 can pull the elliptical strut 6042 to reset and fall back, and under the double actions of the dough extrusion and the reset rotation of the elastic eccentric column 6043, the sliding and lifting elliptical strut 6042 can be quickly reset.

[0063] Please refer to Figures 4-9 , Figures 11-13 , the top pushing mechanism 7 is arranged between the hanging seat 601 and the tray 602, and the top pushing mechanism 7 is used for improving the air flowability by driving the supporting assembly 604 to cyclically extrude the bottom wall of the dough, the top pushing mechanism 7 comprises an arc-shaped sliding groove 701 arranged at two ends of the tray 602 and a toothed column 702 rotatably inserted in the middle of the hanging seat 601, and the toothed column 702 is connected with a toothed disc 703 at one end penetrating to the tray 602.

[0064] The arc-shaped sliding groove 701 is slidingly connected with an arc-shaped toothed plate 704 engaged with the toothed disc 703, one side of the arc-shaped toothed plate 704 extending into the tray 602 is provided with an extension, the extension of the arc-shaped toothed plate 704 is below the elliptical strut 6042, and a driving piece for pushing the elliptical strut 6042 is clamped and installed above the extension of the arc-shaped toothed plate 704, so as to facilitate replacement of the driving piece.

[0065] In the embodiment, the toothed disc 703 is rotated by rotating the toothed column 702, so that the toothed disc 703 is engaged with the arc-shaped toothed plate 704 to drive, since the arc-shaped toothed plate 704 is slidingly connected in the arc-shaped sliding groove 701 arranged at two ends of the tray 602, when the arc-shaped toothed plate 704 slides in the arc-shaped sliding groove 701, the driving piece on the extension can push the elliptical strut 6042 along the arc-shaped track, so that the elliptical strut 6042 can extrude and push the bottom wall of the dough.

[0066] Please refer to Figures 1-4 , Figure 7 , Figure 8 and Figure 13The surfaces of the driving disc 2 and the driven disc 3 are fixed with the guide ring 5 coaxial with the rotating rod 4, the inside of the guide ring 5 is provided with an annular cavity, the tooth column 702 of the hanging seat 601 is inserted into the annular cavity of the guide ring 5;

[0067] The inner surface of the inner ring of the annular cavity is provided with the inner clamping tooth 501 for driving the tooth column 702 to rotate forward, the outer surface of the outer ring of the annular cavity is provided with the outer clamping tooth 502 for driving the tooth column 702 to rotate reversely, and the inner clamping tooth 501 and the outer clamping tooth 502 are distributed in a staggered manner in the annular cavity of the guide ring 5.

[0068] In the embodiment, when the driving disc 2 and the driven disc 3 drive the supporting mechanism 6 to rotate 360°, the supporting mechanism 6 at different positions is always hung and placed, so that the tooth column 702 inserted into the hanging seat 601 moves along the annular cavity inside the guide ring 5, when the tooth column 702 engages with the inner clamping tooth 501 on the inner surface of the inner ring of the annular cavity, the tooth column 702 rotates forward and drives the arc-shaped tooth plate 704 to move forward along the arc-shaped sliding groove 701 through the tooth disc 703, when the tooth column 702 engages with the outer clamping tooth 502 on the outer surface of the outer ring of the annular cavity, the tooth column 702 rotates reversely and drives the arc-shaped tooth plate 704 to move reversely along the arc-shaped sliding groove 701 through the tooth disc 703.

[0069] Please refer to Figure 9 and Figure 12 The driving member for pushing the elliptical supporting bars 6042 is the double convex pushing block 706, the convexes on the surface of the double convex pushing block 706 are designed in a separated manner, and the distance between the two separated convexes is enough to hold two adjacent elliptical supporting bars 6042, and the arc-shaped tooth plate 704 is used for spacing and pushing the elliptical supporting bars 6042 through the double convex pushing block 706 on the extension part.

[0070] In the embodiment, when the arc-shaped tooth plate 704 moves forward or reversely along the arc-shaped sliding groove 701, the arc-shaped tooth plate 704 pushes the elliptical supporting bars 6042 in one direction through the separated double convex pushing block 706 on the extension part, so that the two spaced elliptical supporting bars 6042 can be alternately pushed upward, and the bottom wall of the dough to be leavened can be alternately and spaced pressed, so that the position of the dough pressed can be locally shaken and pressed in a non-adjacent position, and the elliptical supporting bar 6042 between the two elliptical supporting bars 6042 can be separated from the dough to be leavened, when all the elliptical supporting bars 6042 are lifted upward, the elliptical supporting bars 6042 can reduce the adhesion degree with the dough, so that the dough is not excessively adhered to the elliptical supporting bars 6042 when the leavened dough is taken out, and the dough is not excessively remained when the dough is taken out;

[0071] When the tooth column 702 moves in the guide ring 5 and alternately engages with the inner clamping tooth 501 and the outer clamping tooth 502 in the forward and reverse directions, the arc-shaped tooth plate 704 can complete the reciprocating forward movement and reverse movement along the arc-shaped sliding groove 701, so that the pushing mechanism 7 can drive the oval struts 6042 to continuously shake and press the bottom wall of the dough, which can gradually separate the bottom wall of the dough from the oval struts 6042 and can make the bottom wall of the dough fully circulate with the air, facilitating efficient proofing of the dough.
