Description

Technical Field

[0001] The present invention relates to a dough cradle proofing and conveying unit, belonging to the technical field of food processing. Background Art

[0002] Proofing is an important link in the cooking process. Especially when making pasta such as bread, steamed buns, and steamed stuffed buns, it refers to the process of further placing the preliminarily fermented dough for secondary development. The purpose of this is to allow the gas in the dough to diffuse again, forming a more uniform pore structure, making the dough softer. During the proofing process, the dough will continue to absorb moisture and air in the external environment, which helps the dough to further expand and become softer. At the same time, this process can also make the taste of the dough more delicate and the texture more uniform. The proofing time and temperature also need to be controlled. Too long or too short proofing time, as well as too high or too low temperature, will affect the quality of the final pasta. After proofing, the yeast activity inside the dough is higher and the fermentation effect is better. In the subsequent cooking process, such dough is more likely to form a soft structure, and the final food will have a softer and more delicate taste. Therefore, proofing is an important step indispensable for making high-quality pasta.

[0003] For example, the Chinese utility model patent with the publication number CN222396848U discloses a naan dough proofing box, including a frame, which is used for positioning the naan dough proofing box. One side of the frame is fixedly provided with a dough proofing mechanism, and the inner wall of the frame is fixedly provided with an auxiliary positioning mechanism; the dough proofing mechanism includes a heating pipe, one side of the heating pipe is fixedly connected to one side of the frame, a humidifier is fixedly provided at the bottom end of one side of the frame, a fan fixing frame is fixedly provided at one end of the top of the frame, and a rotor is rotatably provided at the middle position of the fan fixing frame, and blade pieces are fixedly provided on the outer wall of the rotor.

[0004] The above-mentioned solution has the following deficiencies in actual use: This solution uses a rotor and blade pieces to achieve air flow. In actual use, the blade pieces will always blow the hot air to the same position, which will cause uneven heating of the bread cakes in the proofing box. The bread cakes blown by the hot air all the time will be over-proofed, while the bread cakes far away from the blade pieces will not be proofed thoroughly, resulting in uneven proofing degree of the bread cakes in the proofing box, thus affecting the taste and quality of the food.

The dough pieces are carried by the circulating bearing part for circulating movement. The circulating bearing part includes two chains 14 and a number of sprockets 15. The two chains 14 are symmetrically arranged. One chain 14 is in meshing transmission connection with a number of sprockets 15. One chain 14 and the number of sprockets 15 meshing with it form a set of circulating mechanism, with a total of two sets of circulating mechanisms. The two sets of circulating mechanisms are symmetrically arranged. A number of cradle components are provided between the two chains 14. The cradle component includes a U-shaped cradle 17. Sleeve 18 is fixedly provided on the two sides of the U-shaped cradle 17 that are far away from each other.

During the proofing period, the hot air can act on the dough pieces through the bearing flower rack 20. Moreover, during the proofing period, due to gravity, even if the chain 14 moves, the bottom of the U-shaped cradle 17 will always be basically in a horizontal state, so that the dough pieces will not fall.

[0024] In order to be able to make the chain 14 move, as Figures 4 - 6 ,Figure 13 As shown, a connecting shaft 16 is fixedly arranged inside the sprocket wheel 15. One end of a connecting shaft 16 is rotatably connected to the inner wall of the loading outer shell 3, one ends of several connecting shafts 16 are rotatably connected to the inner wall of the unloading outer shell 4, one ends of several connecting shafts 16 are rotatably connected to the inner wall of the box body 1, and one ends of several connecting shafts 16 are rotatably connected to one side of the vertical partition plate 5. A rotating assembly is arranged on one side of the box body 1. The rotating assembly is used to drive the two chains 14 to move synchronously. The rotating assembly includes a transmission shaft 21. The transmission shaft 21 is located between the two chains 14. The transmission shaft 21 is fixed between the two connecting shafts 16. A through hole is arranged on one side of the loading outer shell 3. One connecting shaft 16 connected to the transmission shaft 21 is rotatably connected to the inside of the through hole. All the connecting shafts 16 are in a state where they can only rotate and cannot move, that is, the connecting shafts 16 are all arranged in a rotatably connected and immovable state. A bottom plate 23 is fixedly arranged on the outer wall of the box body 1. An electric motor 24 is fixedly arranged on the upper side of the bottom plate 23. The shaft end of the electric motor 24 is connected to the connecting shaft 16 connected to the inside of the through hole through a belt and a pulley. When in use, when it is necessary to make the chain 14 move to convey the cake blank, only need to control the electric motor 24 to rotate at a constant speed. The electric motor 24 will drive a connecting shaft 16 to rotate through the belt and the pulley. This connecting shaft 16 can drive another connecting shaft 16 to rotate through the transmission shaft 21. The two connecting shafts 16 with rotational power can respectively drive the two chains 14 to move, so that the two chains 14 can move synchronously, and the two ends of the U-shaped swing frame 17 can always be in a flush state, so as to realize the conveyance of the cake blank, prevent the cake blank from staying at the same position for a long time, and further make the degree of heat fermentation of the cake blank uniform. It can convey the cake blank from the loading part to the unloading part, realize the continuous processing of the cake blank, and has a high processing efficiency. The electric motor 24 is externally connected to a power supply and a switch through a wire. A motor cover is fixedly arranged on the upper side of the bottom plate 23. A belt cover is fixedly arranged on one side of the motor cover.

[0025] To provide the temperature and humidity required for the fermentation of the cake blank, such as Figures 3 - 4 、 Figure 14As shown, a heating and humidifying part is provided inside the main body part. The heating and humidifying part is used to increase the temperature and humidity inside the box body 1. The vertical partition board 5 is located between the circulation and bearing part and the heating and humidifying part. The vertical partition board 5 can separate the circulation and bearing part from the heating and humidifying part, so that air can circulate. Several temperature sensors and humidity sensors are fixed inside the box body 1 to assist in the control of temperature and humidity. The heating and humidifying part includes several mounting plates 8. The mounting plates 8 are fixed between the vertical partition board 5 and the back board 2. Mounting holes are provided on the upper side of the mounting plates 8. A fan 9 is fixedly provided inside the mounting holes. An electric heating tube 10 is provided below the fan 9. The electric heating tube 10 is fixed on the back board 2. Two water tanks 11 are provided inside the box body 1. Before use, an appropriate amount of pure water needs to be added to the water tanks 11. An electronic water level gauge is provided inside the water tanks 11. The water tanks 11 are located below the electric heating tubes 10. Several support legs 12 are fixedly provided on the lower side of the water tanks 11. The lower ends of the support legs 12 are fixed on the upper side of the bottom of the box body 1. A heating tube 13 is fixedly provided inside the water tanks 11. The fan 9, the electric heating tube 10 and the heating tube 13 are all externally connected to a power supply and a controller through wires. The electronic water level gauge, the temperature sensors and the humidity sensors are electrically connected to the controller through wires. When proofing the cake blanks, the fan 9, the electric heating tube 10 and the heating tube 13 need to be turned on. The heating tube 13 can accelerate the evaporation of the pure water in the water tanks 11. The air outlet of the fan 9 can generate an air flow. The air flow can pass through the electric heating tube 10 and carry away the heat on the electric heating tube 10, so as to generate hot air. The hot air can carry steam into the lower air duct, and then move upward through the gap between the air dispersion holes 7 and the horizontal partition board 6 and the box body 1, acting on the cake blanks, so as to accelerate the proofing of the cake blanks. After passing through the cake blanks, the hot air will enter the upper air duct and then return to the air inlet of the fan 9, so as to realize automatic circulation, and make the temperature and humidity inside the box body 1 more uniform.

[0026] In order to make the hot air disperse evenly, as Figures 3 - 4 , Figures 7 - 8 , Figures 10 - 12 , Figures 14 - 16As shown, a guide portion is provided on the lower side of the circulating bearing portion, and the guide portion includes a plurality of swing shafts 25. A plurality of evenly distributed through holes are provided on the upper side of the transverse partition 6. The swing shafts 25 are rotatably connected to the inner sides of the through holes respectively. A guide plate 26 and a force block 27 are fixedly provided on the outer periphery of the swing shaft 25. When the chain 14 moves, it can drive the guide portion to swing to change the blowing direction of the hot air. Specifically, a plurality of toggle blocks 22 are fixedly provided on one side of a chain 14, and the straight-line distance between two adjacent toggle blocks 22 is the same. The force block 27 matches the toggle block 22, and the force block 27 can contact the toggle block 22. When the chain 14 moves, it can drive the toggle block 22 to move together. The bottom of the chain 14 is in a horizontal state, so the chain 14 can drive the toggle block 22 below to do translational motion. When the toggle block 22 moves horizontally, it can automatically approach and contact the force block 27. When the toggle block 22 contacts the force block 27 and continues to move, it can push the force block 27 to make the swing shaft 25 rotate. The guide plate 26 is located on the lower side of the diaphragm 6. The two sides of the guide plate 26 that are far away from each other are provided with limit blocks 28. The limit blocks 28 are fixed on the upper side of the bottom of the box body 1. The force block 27 is located above the diaphragm 6. The swing shaft 25 can drive the guide plate 26 to rotate. When the guide plate 26 rotates, it can change the flow direction of the hot air in the lower air duct, and can also ensure that each air diffusion hole 7 will not be without hot air outflow for a long time, thereby achieving: driving the guide part to swing by the circulating bearing part to change the blowing direction of the hot air, which can further make the degree of heating and proofing of the cake blank uniform, and can ensure the quality of the cake blank.

[0027] In order to prevent the guide plate 26 from rotating due to the blowing force of the airflow, Figure 9 As shown, a damping positioning assembly is provided on one side of the guide plate 26, and the damping positioning assembly includes a T-shaped frame 29, a connecting sleeve 30 is slidably provided on the outer periphery of the T-shaped frame 29, a supporting sheet 31 is provided above the T-shaped frame 29, a plurality of springs 32 are fixedly provided between the T-shaped frame 29 and the supporting sheet 31, the connecting sleeve 30 and the supporting sheet 31 are fixed on one side of the guide plate 26, a square frame seat 33 is fixedly provided at the lower end of the T-shaped frame 29, a plurality of hemispherical holes are provided on the lower side of the square frame seat 33, a wear-resistant ball 34 is rotatably provided on the inner side of the hemispherical hole, and a plurality of damping seats 35 are fixedly provided on the inner side of the square frame seat 33 The damping seat 35 matches the wear-resistant ball 34, and the damping seat 35 can contact the wear-resistant ball 34. A wear-resistant guide rail 36 is fixedly provided on the upper side of the bottom of the box body 1. The wear-resistant guide rail 36 is an arc-shaped structure. The wear-resistant guide rail 36 matches the wear-resistant ball 34, and the wear-resistant ball 34 contacts the wear-resistant guide rail 36. The friction between the wear-resistant guide rail 36 and the wear-resistant ball 34 and the friction between the damping seat 35 and the wear-resistant ball 34 can prevent the guide plate 26 from rotating due to the blowing force of the airflow, so that the guide plate 26 has the ability of automatic positioning, and can ensure that the hot air is evenly dispersed.

[0028] In order to speed up the rotation frequency of the guide plate 26 and reset the guide plate 26, as shown in FIG.Figure 12 , Figures 14 - 16 As shown, a reset assembly is provided between two adjacent guide plates 26, and the linear spacing between two adjacent toggle blocks 22 is twice the spacing between two adjacent guide plates 26. In another embodiment, the linear spacing between two adjacent toggle blocks 22 is more than twice the spacing between two adjacent guide plates 26. The reset assembly includes a tilted push rod 37, which can contact the two guide plates 26. A guide seat 38 is slidably sleeved on the outer periphery of the tilted push rod 37, and the guide seat 38 is fixed on the upper side of the bottom of the box body 1. When one guide plate 26 rotates due to the push of the toggle block 22, the tilted push rod 37 can push the other guide plate 26 to rotate or reset, thereby increasing the rotation frequency of the guide plate 26 and enabling the next toggle block 22 to contact the force block 27, thereby ensuring that the guide plate 26 can rotate continuously and intermittently to evenly disperse the hot air.

[0029] The working process of this embodiment is: through the cooperation of the loading part, the circulating carrying part and the unloading part, the continuous proofing of the cake dough is realized. During the proofing process of the cake dough, the temperature and humidity of the cake dough during proofing are guaranteed by the heating and humidifying part. At the same time, the circulating carrying part drives the guide part to swing to change the blowing direction of the hot air, so that the degree of heat and proofing of the cake dough is uniform.
