Description

Technical Field

[0001] The invention belongs to the field of food processing equipment, and in particular relates to an ultrasonic dough-proofing device. Background Art

[0002] When preparing pasta, the dough needs to be rested after kneading to loosen the internal gluten structure of the dough, facilitate subsequent kneading and shaping, and improve the taste when eaten.

[0003] In order to speed up the dough proofing process and improve the dough proofing quality, as well as to increase the bound water content in the dough after proofing, ultrasonic technology can be introduced to apply ultrasonic vibrations to the dough so that the dough can be efficiently proofed. However, current ultrasonic equipment inserts a probe into the dough for vibration. Since the dough has a soft and fluffy structure, when the dough is large in volume, the vibration caused by the ultrasonic wave is blocked by the fluffy air cavity of the dough, resulting in uneven proofing. In addition, due to the high cost of the probe, it cannot be equipped in large quantities, and the efficiency of ultrasonic proofing is not high. Summary of the invention

[0004] In order to solve the above problems in the prior art, the present invention provides an ultrasonic dough proofing device, which makes the dough proofing uniform and improves the proofing efficiency.

[0005] The specific technical solution adopted by the present invention is:

[0006] The ultrasonic dough proofing device comprises a dough conveyor belt and an ultrasonic device arranged on a frame, wherein a holding mechanism is arranged on the dough conveyor belt, and the holding mechanism passes through the ultrasonic device by virtue of the movement of the dough conveyor belt, the ultrasonic device is a water tank provided with an ultrasonic generator, and the holding mechanism is a clamping plate and a sealing structure with both ends placed on the dough conveyor belt, and when the dough conveyor belt passes through the ultrasonic device, the clamping plate clamps and flattens the dough by virtue of the narrowing of the dough conveyor belt and the dough droops into the water tank of the ultrasonic device.

[0007] The dough conveyor belt is a chain belt type conveyor belt symmetrically arranged on both sides. The clamping plate is provided with two pieces and is hinged in a V shape. The two ends of the clamping plate are connected to the chain belts on both sides of the dough conveyor belt by means of connecting silicone sheets.

[0008] The sealing structure is an elastic silicone sheet, which is arranged at the V-shaped openings on both sides of the clamping plate. The clamping plate is formed into a bucket-shaped structure with an open upper end by means of the elastic silicone sheets arranged on both sides.

[0009] The dough conveyor belt is sequentially arranged into a feeding section, a proofing section and a unloading section along the forward direction; the width between the support rollers of the dough conveyor belts of the feeding section and the unloading section is greater than the width between the support rollers of the proofing section; a trumpet-shaped extrusion section is formed between the feeding section and the proofing section, and a trumpet-shaped opening section is formed between the proofing section and the unloading section.

[0010] The unloading section is also provided with a folding support wheel, and the dough conveyor belt is folded toward the lower side of the frame by means of the folding support wheel.

[0011] The frame is also provided with a feeding conveyor belt, which is located above the feeding section, and a discharging conveyor belt is provided below the discharging section.

[0012] The proofing section of the dough conveyor belt is arranged above the ultrasonic device. With the help of the reduced gap between the supporting rollers of the proofing section, the clamping plate flattens the dough and hangs down into the water tank of the ultrasonic device.

[0013] The beneficial effects of the present invention are:

[0014] The present invention sets a water tank as an ultrasonic device, uses water as a vibration transmission medium and reduces the temperature with the help of water, ensures that the dough is vibrated over a large area and prevents the dough from heating up and maturing due to the ultrasonic vibration. The dough is flattened by clamping the plywood so that both the inside and outside of the dough can receive the ultrasonic vibration, thereby improving the uniformity of proofing and ensuring a better taste of the made pasta.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0020] Specific implementation examples Figure 1 and Figure 2As shown, the present invention is an ultrasonic dough proofing device, comprising a dough conveyor belt 1 and an ultrasonic device 2 arranged on a frame, wherein a holding mechanism is arranged on the dough conveyor belt 1, and the holding mechanism passes through the ultrasonic device 2 by means of the movement of the dough conveyor belt 1, the ultrasonic device 2 is a water tank provided with an ultrasonic generator, and the holding mechanism is a clamping plate 3 and a sealing structure with both ends placed on the dough conveyor belt 1, and when the dough conveyor belt 1 passes through the ultrasonic device 2, the clamping plate 3 clamps the dough flat and droops into the water tank of the ultrasonic device 2 by means of the narrowing of the dough conveyor belt 1.

[0021] The present invention Figure 1 As shown, the dough conveyor belt 1 is supported by a frame so that the dough conveyor belt 1 can rotate relative to the frame. The dough conveyor belt 1 carries the containing mechanism and is immersed in the water tank of the ultrasonic generator. With the help of water as the transmission medium, the dough clamped in the clamping plate 3 is in an ultrasonic vibration environment, and the proofing effect is improved with the help of ultrasonic waves.

[0022] With the help of the narrowing of the spacing between the dough conveyor belts 1, the clamping plates 3 are locked together, thereby forming the dough into a pancake shape, reducing the thickness of the dough and increasing its diameter, thereby facilitating the dough to receive ultrasonic vibrations and improving the uniformity of ultrasonic fermentation of the dough.

[0023] Further, such as Figure 2 and Figure 3 As shown, the dough conveyor belt 1 is a chain-belt conveyor belt symmetrically arranged on both sides, the clamping plate 3 is provided with two pieces and is hinged in a V shape, and the two ends of the clamping plate 3 are connected to the chain belts on both sides of the dough conveyor belt 1 by means of connecting silicone sheets 13.

[0024] like Figure 2 As shown, with the help of the soft and elastic connecting silicone sheet 13, the hard clamping plate 3 can move smoothly on the dough conveyor belt 1 with varying widths. The connecting silicone sheet 13 is made of food-grade silicone. When the spacing of the dough conveyor belt 1 is narrowed, the dough falling between the clamping plates 3 is pulled along with the chain belt with the help of the connecting silicone sheet 13, so that the dough is formed into a pancake under gentle force, which is convenient for ultrasonic penetration.

[0025] Further, such as Figure 3 As shown, the sealing structure is an elastic silicone sheet 4, which is arranged at the V-shaped openings on both sides of the clamping plate 3. The clamping plate 3 is formed into a bucket-shaped structure with an open upper end by means of the elastic silicone sheets 4 arranged on both sides.

[0026] Since water is used as the ultrasonic transmission medium, in order to prevent water from entering between the splints 3 and causing the dough to be soaked in water, an elastic silicone sheet 4 is sealed at the V-shaped opening of the splint 3. When the splint 3 is opened, the elastic silicone sheet 4 is pulled open by the pulling of the splint 3, and together with the splint 3, a bucket-shaped structure is formed, thereby ensuring that the dough does not fall out when the dough falls in. When the splint 3 squeezes the dough, the elastic silicone sheet 4 is blocked at the opening on the side of the splint 3 by its own elasticity, and at the same time accommodates the squeezed out part of the dough. The splint 3 is a hard glass plate, and at the same time, the splint 3 acts as a counterweight to prevent the whole from floating on the water surface. The elasticity of the elastic silicone sheet 4 is used to accommodate the squeezed dough, and at the same time, the contact with water is more direct. Therefore, even if a large amount of dough is squeezed out and it is formed into a ball again, it can also have a good ultrasonic proofing effect.

[0027] Further, such as Figure 2 As shown, the dough conveyor belt 1 is sequentially arranged into a feeding section 5, a proofing section 6 and a unloading section 7 along the forward direction, the width between the support rollers of the dough conveyor belt 1 of the feeding section 5 and the unloading section 7 is greater than the width between the support rollers of the proofing section 6, a trumpet-shaped extrusion section 8 is formed between the feeding section 5 and the proofing section 6, and a trumpet-shaped opening section 9 is formed between the proofing section 6 and the unloading section 7.

[0028] The unloading section 7 is also provided with a folding support wheel 10, and the dough conveyor belt 1 is folded toward the lower side of the frame by means of the folding support wheel 10.

[0029] The frame is also provided with a feeding conveyor belt 11 , which is located above the feeding section 5 , and a discharging conveyor belt 12 is provided below the discharging section 7 .

[0030] The proofing section 6 of the dough conveyor belt 1 is arranged above the ultrasonic device 2. By reducing the gap between the supporting rollers of the proofing section 6, the clamping plate 3 flattens the dough and hangs down into the water tank of the ultrasonic device 2.

[0031] When the present invention is in use, the dough kneading process is connected with the aid of the feeding conveyor belt 11. After the dough is kneaded and cut, it is intermittently fed into the containing device located in the feeding section 5 through the feeding conveyor belt 11, and finally the dough falls onto the clamping plate 3. The dough conveyor belt 1 rotates at a constant speed. When the containing device moves to the extrusion section 8, the dough conveyor belt 1 is narrowed in a trumpet shape. At this time, the flexible connecting silicone sheet 13 is deformed along with the dough conveyor belt 1, and the two hinged clamping plates 3 are pulled to clamp the dough on the clamping plates 3 to form a dough cake. As the excess part of the dough cake is squeezed out of the clamping plate 3, the elastic silicone sheet 13 is supported. Sheet 4 is used to prevent the elastic silicone sheet 4 from being clamped between the clamping plates 3, thereby ensuring the ultrasonic proofing quality of the dough. As the clamping plates 3 are gradually clamped, the clamping plates 3 gradually sag and immerse in the water tank. As the dough conveyor belt 1 continues to move forward, the dough is immersed in the water tank for the required time to proof. When the containing device moves to the opening section 9, the clamping plates 3 are gradually pulled apart and pulled out of the water tank. After passing through the folding support wheel 10, the opened clamping plates 3 face downward, and the dough falls onto the discharging conveyor belt 12, thereby realizing the automatic discharging of the dough, realizing the continuous ultrasonic proofing of the dough, and ensuring production efficiency.
