DETAILED DESCRIPTION

[0026] In practical applications, softer dough or dough mixed with potato starch is easy to squeeze out a small amount of water during the calendering operation. In other applications, in order to enhance the flavor of the product, green onion tubes (small pieces of green onion cut into pieces) can be sprinkled on the dough, and when the calendering component performs the calendering operation on the dough, the green onion tubes will also squeeze out water. The products here include but are not limited to biscuits.

[0027] The squeezed water will adhere to the calendering roller. When the roller with water adheres to the dough band performs the calendering operation on the dough band behind, the stickiness of the dough band increases, which is easy to cause the dough band to break. Slightly damaged dough bands will affect the shape of the biscuits, and severe damage will cause some areas of the dough band to be unable to be made into biscuits, thus affecting the biscuit production capacity.

[0028] To address this problem, the present invention provides a calendering device, in which a flour feeding assembly is provided. The flour feeding assembly provides flour to the calendering assembly, and the flour is used to absorb the liquid on the calendering assembly, thereby reducing the occurrence of dough strip breakage and improving production capacity.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] An embodiment of the present invention provides a calendering device, the calendering device comprising:

[0031] A calendering assembly for performing a calendering operation on the facing strip;

[0032] And a flour supply component is used for supplying flour to the calendering component to absorb the liquid on the calendering component.

[0033] Compared with the existing calendering equipment, by adding a flour feeding assembly, flour can be provided to the calendering assembly, and then the flour can be used to absorb the liquid adhering to the calendering assembly to avoid the damage of the dough strip, and finally the production capacity can be effectively improved. The liquid adhering to the calendering assembly includes but is not limited to water, and can also be other liquids, such as oil, sugar solution, etc.

[0034] In a specific implementation, the calendering assembly and the flour feeding assembly may have a variety of structures, which are not limited here.

[0035] Figure 1 It is a schematic diagram of the three-dimensional structure of a calendering device in one embodiment of the present invention. Figure 2 for Figure 1 Cross-sectional view of the side view of the calendering equipment.

[0036] Reference Figure 1 and Figure 2 In one embodiment, the calendering device includes: a calendering component 10 and a flour feeding component 20.

[0037] In a specific implementation, the calendering assembly 10 is used to perform a calendering operation on the dough band 30, that is, the process of thinning the dough band from thick. Taking the biscuit making process as an example, 3 to 4 calendering operations are usually required. If the initial thickness of the dough band is 25 mm, it undergoes 4 calendering operations. After the first calendering operation, the thickness of the band becomes 12 mm, after the second calendering operation, the thickness of the band becomes 5 mm, after the third calendering operation, the thickness of the band becomes 2 mm, and after the fourth calendering operation, the thickness of the band becomes 1 mm. Subsequently, the 1 mm thick dough band is cut into pieces of biscuits using a mold and then baked.

[0038] In a specific implementation, the calendering assembly 10 includes: a first roller 101 and a second roller 102 ; the first roller 101 and the second roller 102 rotate in opposite directions and are located on opposite sides of the dough strip 30 .

[0039] In one embodiment, the first roller 101 and the second roller 102 are placed in a vertical direction. Specifically, the first roller 101 can be located above the dough belt 30, and the second roller 102 can be located below the dough belt 30.

[0040] In another embodiment, the first roller 101 and the second roller 102 may also be placed in the horizontal direction. Specifically, the first roller 101 may be located on the left side of the dough belt 30 , and the second roller 102 may be located on the right side of the dough belt 30 .

[0041] In practical applications, the dough belt 30 can be placed on a conveyor belt. No matter how the first roller 101 and the second roller 102 are placed, the dough belt 30 can be transferred from one side of the calendering assembly 10 to the other side of the calendering assembly 10 through the gap between the first roller 101 and the second roller 102. The first roller 101 is in direct contact with the dough belt 30, and the second roller 102 is also in direct contact with the dough belt 30.

[0042] In a specific implementation, a protective cover 103 may be provided outside the first roller 101, and the protective cover 103 wraps the first roller 101 and rotates synchronously with the first roller 101. The protective cover 103 is used to prevent the dough belt 30 from falling toward the edge of the first roller 101.

[0043] In a specific implementation, the conveying direction of the dough strip 30 matches the rotation direction of the first roller 101 and the second roller 102. Figure 2 Assuming that the conveying direction of the dough belt 30 is direction A, at this time, the first roller 101 should rotate counterclockwise and the second roller 102 should rotate clockwise.

[0044] In a specific implementation, the gap between the first roller 101 and the second roller 102 is adjustable. For example, at least one of the first roller 101 and the second roller 102 may be connected to a driving motor, and the driving motor drives the connected roller to move, thereby changing the gap between the first roller 101 and the second roller 102, so that the gap between the first roller 101 and the second roller 102 matches the required dough strip thickness.

[0045] In a specific implementation, the flour supply assembly 20 may include: a flour storage trough 201, wherein the flour storage trough 201 includes a trough wall and a discharge port surrounded by the trough wall, and flour is provided to the calendering assembly 10 through the discharge port.

[0046] Specifically, the gap between the discharge port and the calendering assembly 10 can be set to be small enough. Flour is stored in the flour storage tank 201. When the dough strip 30 is squeezed by the upper and lower rollers, when liquid adheres to the first roller 101, the adhered liquid will protrude from the surface of the first roller 101. When the first roller 101 adhered with liquid passes through the discharge port of the flour storage tank 201, the liquid on the first roller 101 will stick to some flour from the discharge port, and the sticky flour will absorb or even dry the liquid adhered to the first roller 101.

[0047] In a specific implementation, the flour storage tank 201 can have a variety of implementation methods, which are not limited here.

[0048] Specifically, refer to Figure 1The flour storage trough 201 may include: a first trough wall 201a perpendicular to the rotation direction of the calendering assembly 10, a second trough wall 201b and a third trough wall 201c parallel to the rotation direction of the calendering assembly 10, and a fourth trough wall 201d; the first trough wall 201a is connected to one end of the second trough wall 201b and the third trough wall 201c, the fourth trough wall 201d is connected to the other end of the second trough wall 201b and the third trough wall 201c, and the edges of the first trough wall 201a, the second trough wall 201b, the third trough wall 201c and the fourth trough wall 201d close to the calendering assembly 10 form the discharge port.

[0049] In a specific implementation, the discharge port can be fitted with the surface of the first roller 101, that is, the shape formed by the edge of the first groove wall 201a, the second groove wall 201b, the third groove wall 201c and the fourth groove wall 201d close to the calendering component 10 is the same as the surface shape of the first roller 101, but there is a certain gap between the first groove wall 201a and the fourth groove wall 201d and the first roller 101, and the gap enables the first roller 101 to rotate unimpeded, and when liquid adheres to the surface of the first roller 101, the liquid adhered to the first roller 101 can be made to stick to the flour from the discharge port.

[0050] In one embodiment, the fourth groove wall 201d includes two parts, a vertical part 201d1 and an inclined part 201d2. The vertical part 201d1 is perpendicular to the rotation direction of the first roller 101, and the inclined part 201d2 is inclined from one end of the vertical part 201d1 toward the first roller 101.

[0051] In a specific implementation, the projection of the discharge port on the first roller 101 does not exceed the highest point of the first roller 101 perpendicular to the transmission direction of the dough belt 30, thereby allowing the flour to tilt in the same direction rather than in multiple directions.

[0052] Specifically, refer to Figure 2 The first groove wall 201a can be set to surround the edge of the discharge port, and the projection on the first roller 101 does not exceed the highest point of the first roller 101 in the direction perpendicular to the transmission direction of the dough belt 30. In this way, the flour in the flour storage groove 201 will tilt toward the fourth groove wall 201d.

[0053] In a specific implementation, the flour feeding assembly 20 may further include: a scraper 202 , which is disposed on the trough wall of the flour storage trough 201 and extends toward the first roller 101 .

[0054] Specifically, refer to Figure 2Assuming that the first roller 101 rotates in the counterclockwise direction, a scraper 202 can be provided on the first groove wall 201a of the flour storage groove 201, and the first end of the scraper 202 can be fixed on the first groove wall 201a, and the scraper 202 can extend from the first groove wall 201a to the direction of the first roller 101. The second end of the scraper 202 is close to the surface of the first roller 101, and there is a certain gap between the first roller 101 and the surface, and the second end of the scraper 202 is opposite to the first end. In this way, the scraper 202 can remove the excessively thick flour on the surface of the first roller 101, and prevent the excessive flour from adhering to the surface of the first roller 101, causing waste and affecting the quality of the dough strip.

[0055] In a specific implementation, the width of the scraper 202, i.e., the distance from the first end to the second end of the scraper 202, can be set according to the distance between the edge of the first groove wall 201a surrounding the discharge port and the first roller 101. The length of the scraper 202 can be less than or equal to the length of the first groove wall 201a, and the position of the scraper 202 on the first groove wall 201a can be adjusted according to the position on the surface of the first roller 101 where liquid is easily adhered. There is a gap between the second end of the scraper 202 and the first roller 101, and the gap range is (0, 10mm].

[0056] In a specific implementation, the gap between the second end of the scraper 202 and the surface of the first roller 101 can be fixedly set according to actual needs.

[0057] In one embodiment, the gap between the second end of the scraper 202 and the first roller 101 is adjustable. In practical applications, the gap between the second end of the scraper 202 and the first roller 101 can be adjusted according to the actual adhesion of flour on the surface of the first roller 101.

[0058] Specifically, a scraper driving assembly may be provided on the first groove wall 201 a to drive the scraper 202 to move along the surface of the first groove wall 201 a , thereby changing the gap between the second end of the scraper 202 and the first roller 101 .

[0059] In other embodiments, multiple clamping positions may be symmetrically arranged on both sides of the first groove wall 201 a , and the scraper 202 may be fixed at different clamping positions to change the gap between the second end of the scraper 202 and the first roller 101 .

[0060] In one embodiment, Figure 3 yes Figure 1 Top view of the calendering equipment. Figure 3The flour feeding assembly 20 may further include: a stirring structure 203 located in the flour storage trough 201 , and the stirring structure 203 moves along the rotation direction of the calendering assembly 10 to stir the flour in the flour storage trough 201 .

[0061] In a specific implementation, the stirring structure 203 may include a stirring shaft 203a fixed on the second groove wall 201b and the third groove wall 201c, and a stirring paddle 203b arranged circumferentially along the stirring shaft 203a. The stirring shaft 203a is rotatable, and when the stirring shaft 203a rotates, the stirring paddle 203b can be driven to move circumferentially along the stirring shaft 203a. The stirring shaft 203a can be arranged at a position close to the fourth groove wall 201d, so that when the flour is tilted toward the fourth groove wall 201d, the flour can be stirred to prevent the flour from bridging or hanging.

[0062] In some embodiments, reference Figure 2 The flour supply assembly 20 may further include a flour position sensor 204 , which may be installed in the flour storage trough 201 to monitor the amount of flour in the flour storage trough 201 .

[0063] In a specific implementation, the flour position sensor 204 can be implemented by a sensor. The flour position sensor 204 can be located at a position above the highest point of the stirring structure 203 on the second groove wall 201b and the third groove wall 201c along the direction perpendicular to the dough strip.

[0064] In one embodiment, the flour position sensor 204 may include: a signal transmitting end and a signal receiving end, wherein the signal transmitting end may be arranged on the second slot wall 201b, and the signal receiving end may be arranged on the third slot wall 201c. The signal transmitting end may continuously send a signal to the signal receiving end, and the signal receiving end may receive the signal sent by the signal transmitting end.

[0065] Specifically, when the amount of flour in the flour storage tank 201 is lower than the position of the signal receiving end, the signal receiving end is exposed to the flour, and the signal receiving end can receive the signal. After receiving the signal, the signal receiving end can output a prompt signal to prompt the user to add flour to the flour storage tank 201 to prevent the flour in the flour storage tank 201 from being too little and affecting the quality of the dough. There is no limitation on the specific output method of the prompt signal. For example, the prompt signal can be output by lighting a light or by voice.

[0066] In actual applications, when the calendering component 10 performs a calendering operation on the dough strip 30, a little oil and a little water will adhere to the calendering component 10 on the dough strip 30, specifically adhere to the first roller 101 of the calendering component. After the oil and water are adhered to the first roller 101, performing a calendering operation on the dough strip 30 will affect the integrity of the dough strip 30, thereby affecting the product's production capacity.

[0067] In some applications, in order to enhance the flavor of the product, green onion tubes are sprinkled on the dough belt 30, and when the calendering assembly 10 performs the calendering operation on the dough belt 30, a small amount of green onion tubes will also adhere to the first roller 101. After the green onion tubes are adhered to the first roller 101, the calendering operation is performed on the dough belt 30, which will affect the smoothness of the green onion tubes falling everywhere and calendering, thereby affecting the production capacity of the product.

[0068] To address this problem, in one embodiment of the present invention, the calendering device may further include: a cleaning component for performing a cleaning operation on the calendering component 10. The cleaning component can remove most of the excess material adhering to the calendering component 10. The excess material includes but is not limited to oil, water, green onion tubes, etc. The remaining excess material (mainly liquid excess material) is then adhered to the flour through the flour storage tank 201, so that the flour absorbs or even absorbs the liquid excess material to ensure smooth calendering.

[0069] In a specific implementation, the cleaning component may be implemented in a variety of ways, which are not limited here.

[0070] In one embodiment, referring to Figure 1 and Figure 2 The cleaning component includes: a blade 401 and a recovery groove 402, wherein the blade 401 is used to remove excess material on the calendering component 10, and the recovery groove 402 is used to recover the excess material.

[0071] Specifically, the blade 401 may be located at one side of the first roller 101. During cleaning, the blade edge of the blade 401 may contact the surface of the first roller 101 and be located in the tangent direction of the first roller 101, thereby dropping the excess material from the surface of the first roller 101. The recovery groove 402 is usually located below the blade 401, and the excess material dropped by the blade 401 can fall into the recovery groove 402, thereby avoiding contamination of other components.

[0072] In a specific implementation, the dimension of the first groove wall 201a in the direction perpendicular to the dough strip 30 is substantially the same as the dimension of the vertical portion 201d1 in the direction perpendicular to the dough strip 30. Relative to the first groove wall 201a, the inclined portion 201d2 of the fourth groove wall 201d approaches the first roller 101, and the distance therebetween is between about 1 mm and 3 mm. The blade 401 is disposed below the point B on the surface of the first roller 101, and the line connecting the point B and the center of the first roller 101 is in the horizontal direction.

[0073] During actual production operation, a small amount of flour will fall downward through the gap between the inclined portion 201d2 and the first roller 101 due to its own gravity, and finally fall into the area enclosed between the blade 401 and the first roller 101. Since the gap between the blade 401 and the first roller 101 is small enough, most of the excess material adhering to the first roller 101 can be removed, and the remaining liquid excess material first adheres to the flour falling in the area enclosed between the blade 401 and the first roller 101, and then adheres to the flour again through the flour storage tank 201, thereby improving the flour adsorption effect and ensuring that the calendering assembly 10 is smooth and bright.

[0074] In one embodiment of the present invention, the calendering device may further include: a base, and the calendering component, the flour feeding component and the cleaning component are all fixed on the base.

[0075] Specifically, the first roller 101 and the second roller 102 can span the base and be fixed to the two side walls of the base through corresponding connecting pieces. The flour storage trough 201 can span the base and be fixed to the two side walls of the base through corresponding connecting pieces. The blade 401 and the recovery trough 402 can also span the base and be fixed to the two side walls of the base through corresponding connecting pieces.

[0076] It should be noted that the green onion tube in the embodiment of the present invention refers to the green onion segment formed after fresh green onions are picked, washed, cut off the white part, cut the green onion into small segments, dried, and air-dried, and the length is between 3mm and 6mm.

[0077] By adopting the scheme of the present invention, a flour feeding assembly is arranged in the calendering equipment, so that flour can be provided to the calendering assembly, and the flour is used to absorb the liquid on the calendering assembly, thereby ensuring smooth calendering of the dough band, reducing the damage of the dough band, and ultimately improving the product production capacity.

[0078] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
