Description

Technical Field

[0001] This utility model relates to the field of coffee bread technology, specifically a coffee bread making tool with adjustable temperature in layers. Background Technology

[0002] In the baking process of coffee bread, the bread's crust and internal structure have significantly different sensitivities to temperature. The crust requires a higher temperature to quickly form a crispy and caramelized outer shell, while the internal structure requires a relatively mild temperature environment to ensure a fluffy and soft texture. Traditional baking equipment with single temperature control can no longer meet its refined baking requirements. Therefore, ovens with multi-layer baking structures and support for different temperature settings are gradually being applied to coffee bread making. By setting different temperature fields in different layers, targeted heating of different parts of the bread can be achieved.

[0003] However, existing multi-layer roasting equipment still has significant drawbacks in actual operation: when coffee bread needs to switch between different temperature environments during the roasting process, such as from the low-temperature shaping stage to the high-temperature browning stage, the operator needs to manually remove the tray carrying the bread from one temperature baking layer and then transfer it to another temperature baking layer. This process relies entirely on manual operation, which not only consumes a lot of physical strength and reduces production efficiency, but also makes it difficult to accurately control the time interval of manual transfer, which can easily cause temperature gaps and further lead to unstable roasting results. Therefore, a coffee bread making tool with layered temperature control has been proposed to solve the above problems. Utility Model Content

This process relies entirely on manual operation, which not only consumes a lot of physical strength and reduces production efficiency, but also makes it difficult to accurately control the time interval of manual transfer, easily causing temperature gaps and further leading to unstable baking results.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This embodiment of a coffee bread making tool with adjustable temperature in layers includes a main body 1, with three coffee bread baking mechanisms 2 inside the main body 1, a control mechanism 3 on the right side of the main body 1, and a coffee bread quick layer changing mechanism 4 on the front of the main body 1.

[0025] The coffee bread quick-layer changing mechanism 4 includes a drive box 401, a dual-axis motor 402, a drive shaft 403, a gear set 404, a lifting box 405, a threaded shaft 406, an L-shaped connecting plate 407, a limiting insert 408, a limiting slot 409, a tray support plate 410, a limiting insertion hole 411, a limiting insert plate 412, and a tray limiting strip 413. The drive box 401 is fixedly installed on the top front of the main body 1. The dual-axis motor 402 is fixedly installed inside the drive box 401. Drive shafts 403 are fixedly installed on the left and right output shafts of the dual-axis motor 402. Gear sets 404 are installed on the ends of the two drive shafts 403 furthest from the dual-axis motor 402. The left and right sides of the front of the main body 1... Each side is fixedly installed with a lifting box 405. The inside of each lifting box 405 is rotatably connected with a threaded shaft 406. The opposite side of each lifting box 405 is slidably connected with an L-shaped connecting plate 407. The top of each L-shaped connecting plate 407 is fixedly installed with a limit pin 408. The inside of each L-shaped connecting plate 407 is opened with a limit slot 409. The top of each L-shaped connecting plate 407 is movably installed with a pallet support plate 410. The left and right sides of the pallet support plate 410 are opened with limit holes 411. The bottom of the pallet support plate 410 is fixedly installed with two limit pins 412. The top of the pallet support plate 410 is fixedly installed with two pallet limit strips 413.

[0026] The coffee bread baking mechanism 2 includes a baking chamber 201, an electric heating element 202, and a bread tray 203. The main body of the equipment 1 has three baking chambers 201 inside. The electric heating element 202 is fixedly installed on the inner top wall and inner bottom wall of each baking chamber 201. The bread tray 203 is slidably connected inside each baking chamber 201.

[0027] The control mechanism 3 includes a central control unit 301, a bread baking mechanism control panel 302, an external cable 303, and a foot switch 304. The central control unit 301 is fixedly installed on the right side of the main body 1. Three bread baking mechanism control panels 302 are fixedly installed on the front of the central control unit 301. An external cable 303 is fixedly installed on the outside of the central control unit 301. A foot switch 304 is fixedly installed on the outside of the external cable 303.

[0028] Specifically, before use, the equipment is initialized through the control mechanism 3. The operator sets different temperatures for the three baking chambers 201 through the control panel 302 of the three bread baking mechanisms on the front of the central control unit 301. For example, the upper baking chamber 201 is set to 220℃ for high-temperature browning, the middle chamber is set to 150℃ for low-temperature shaping, and the lower chamber is set to 180℃ for preheating. The bread tray 203 containing the coffee bread dough is pushed into the middle baking chamber 201. At this time, the electric heating components 202 on the top and bottom walls of the middle baking chamber heat up simultaneously, and the bread dough is baked at a low temperature by radiation heating.

[0029] Specifically, when baking enters the layer-changing stage, the operator pauses the operation of the middle layer electric heating component 202, manually pulls the bread tray 203 horizontally out of the middle layer baking chamber 201, and precisely places it on the top of the tray support plate 410. The distance between the two tray limit strips 413 on the top of the tray support plate 410 is consistent with the width of the bread tray 203, which limits its lateral movement and prevents it from shifting during the transfer process.

[0030] Subsequently, the dual-axis motor 402 is powered on and started. Its left and right output shafts drive the first gear in the gear set 404 to rotate through the drive shaft 403. The first gear meshes with the second gear fixed on the top of the threaded shaft 406 to form a gear transmission pair, driving the two threaded shafts 406 to rotate synchronously in the same direction.

[0031] The thread on the outer surface of the threaded shaft 406 engages with the threaded hole on the connecting rod outside the L-shaped connecting plate 407 to form a threaded transmission structure. Since the sliding groove opened on the opposite side of the lifting box 405 limits the movement direction of the L-shaped connecting plate 407, the L-shaped connecting plate 407 moves vertically up and down along the sliding groove through the connecting rod, thereby driving the pallet bearing plate 410 to move synchronously.

[0032] During the lifting process, the limiting pin 408 at the top of the L-shaped connecting plate 407 is inserted into the limiting pin holes 411 on the left and right sides of the pallet support plate 410, while the limiting pin 412 at the bottom of the pallet support plate 410 is inserted into the limiting slot 409 inside the L-shaped connecting plate 407, forming a double mechanical limit in the vertical direction, ensuring that the pallet support plate 410 maintains a horizontal posture during the lifting process, and avoiding tilting or shaking caused by uneven force.

[0033] Specifically, when the tray support plate 410 rises to a position aligned with the horizontal level of the entrance to the upper baking chamber 201 via the threaded drive, the dual-axis motor 402 stops, and the operator pushes the bread tray 203 into the upper baking chamber 201 along the guide bar 413. At this time, the upper electric heating component 202 automatically starts the high-temperature baking program.

[0034] Throughout the entire layer-changing process, the start and stop of the dual-axis motor 402 are controlled by the foot switch 304.

[0035] In summary, this coffee bread making tool with layered temperature control first pulls the bread tray 203 out of one baking chamber 201 and places it on the tray support plate 410. Then, the dual-axis motor 402 drives the gear set 404 via the drive shaft 403 to rotate the threaded shaft 406. The L-shaped connecting plate 407 rises and falls along the sliding groove of the lifting box 405 via the connecting rod. The tray support plate 410 moves accordingly, moving the bread tray 203 to the corresponding baking chamber 201. Finally, the bread tray 203 is pushed into another baking chamber 201. This design, through mechanical linkage and precise control, enables rapid and seamless transitions between different temperature baking layers for coffee bread. Switching between different temperatures saves time and effort, eliminates time errors and temperature gaps, improves roasting efficiency and product stability, and solves the significant defects that still exist in the actual operation of existing multi-layer roasting equipment: when coffee bread needs to switch between different temperature environments during the roasting process, such as from the low-temperature shaping stage to the high-temperature browning stage, the operator needs to manually remove the tray carrying the bread from one temperature baking layer and then transfer it to another temperature baking layer. This process relies entirely on manual operation, which not only consumes a lot of physical strength and reduces production efficiency, but also makes it difficult to accurately control the time interval of manual transfer, which can easily cause temperature gaps and further lead to unstable roasting results.
