Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and in particular to a drying equipment for rice noodle processing. Background Technology

[0002] The drying process in rice noodle processing is one of the key steps to ensure the quality of rice noodles. The purpose of drying is to remove excess moisture from the rice noodles, thereby extending their shelf life and improving their texture and flavor. The usual method for drying rice noodles is to place them in a drying room, then introduce hot air into the drying room. The hot air is circulated through a system to blow the hot air onto the surface of the rice noodles, thus removing the moisture from them.

[0003] The drying methods for rice noodles and rice vermicelli are similar; they are typically placed in a drying room while hanging on drying rods. Patent CN220771679U discloses a drying rack for dried rice vermicelli, including a base plate. Fixed support vertical rods one, two, three, and four are fixedly attached to the top surface of the base plate. Multiple fixed side rods are horizontally fixed between the adjacent sides of fixed support vertical rods one and two, and multiple fixed side rods are horizontally fixed between the adjacent sides of fixed support vertical rods three and four. The rice vermicelli hanging rods in this patent are used to suspend the rice vermicelli, ensuring even exposure to air for better drying.

[0004] However, there are some problems when using drying racks to hang rice noodles and rice vermicelli for drying. For example, the bends of the hanging rice noodles may stick to the drying rack, and the side that is sticking to the drying rack cannot directly contact the hot air, resulting in poor drying effect. Since the hot air usually blows downwards from the top of the drying room, the rice noodles hanging on the upper layer may block the rice noodles on the lower layer, preventing the hot air from blowing directly to the rice noodles on the lower layer. These problems will cause the rice noodles to dry unevenly, resulting in inconsistent quality of rice noodles produced in batches and affecting the overall quality of the rice noodles. Summary of the Invention

[0005] This invention provides a drying device for rice noodle processing to solve the technical problems of uneven drying and inconsistent quality of rice noodles in the prior art.

[0006] To solve the above problems, the present invention provides a drying device for rice noodle processing, which adopts the following technical solution:

[0007] A drying device for rice noodle processing, comprising:

[0008] The drying room is equipped with a hot air system at the top and an exhaust system at the bottom.

[0009] The suspension module is located in the drying room and comprises a hanger and a plurality of drying rods, the plurality of drying rods are arranged in two layers spaced apart in the up-down direction on the hanger, and each layer comprises a plurality of drying rods arranged in the front-back direction and extending in the left-right direction;

[0010] The suspension module further comprises two groups of scissors arms symmetrically arranged on the left and right sides of the hanger, the scissors arms can be extended and retracted in the front-back direction, each group of scissors arms comprises a plurality of scissors groups connected in sequence in the front-back direction by hinges, and each group of scissors comprises two scissors rods connected by a hinge in the middle;

[0011] A vertical extension link rod one is connected to the hinge shaft between each two groups of scissors in the front-back direction, the link rod one is slidingly installed in the front-back direction on the hanger, and the bottom end of the link rod one is located below the scissors arm;

[0012] A vertical extension link rod two is connected to the hinge shaft between the two scissors rods in each group of scissors, the link rod two is slidingly installed in the front-back direction on the hanger, and the top end of the link rod two is located above the scissors arm;

[0013] A drying rod is connected between the bottom ends of each two link rods one in the left-right direction and between the top ends of each two link rods two in the left-right direction;

[0014] The drying rod is hollow inside and is provided with left-right extension grooves in the circumferential direction, and strip-shaped holes extending in the left-right direction are formed in the bottom of the grooves;

[0015] The bottom end of the link rod one and the top end of the link rod two are connected with support pieces, each two support pieces in the left-right direction are symmetrically arranged, the support piece comprises a support plate, an air guide pipe and a moving block, the air guide pipe is slidingly installed on the support plate in the left-right direction, the two ends of the drying rod are respectively inserted into the two air guide pipes symmetrically arranged in the left-right direction, the moving block is connected to the side of the support plate away from the drying rod, the support piece is slidingly installed on the hanger in the front-back direction through the moving block, the moving block is connected with a vertical arrangement of a pushing inclined plate, the side of the air guide pipe facing the moving block is connected with a bearing piece, and in the contraction process of the scissors arm, the corresponding front-back adjacent support pieces are driven to move close to each other, the pushing inclined plate is in contact with the bearing piece on the adjacent support piece and pushes the bearing piece to drive the air guide pipe to move away from the drying rod.

[0016] When the rice powder is dried, the drying rod with the rice powder is first connected between each two groups of support pieces in the left-right direction, and then the scissors arm is driven to extend, so that the rice powder in each layer is uniformly arranged in the front-back direction, and because the link rod one is connected to the hinge shaft between the two adjacent groups of scissors and the link rod two is connected to the hinge shaft between the two scissors rods in the scissors, the two layers of drying rods are automatically staggered after being arranged, so that the two layers of drying rods can be directly blown by the hot air, and the drying effect is better.

[0017] The drying rods are arranged more uniformly by using the scissor arms to drive the drying rods to be arranged in sequence, compared with manually arranging the drying rods in sequence, and the positions of the upper and lower drying rods are more easily controlled to ensure that the drying rods are in an upper and lower staggered state. The scissor arms are initially in a retracted state, the interval between the two adjacent support members is small, and the support members are concentrated on the same side of the hanger. At this time, the drying rods are connected to the support members, and the operator does not need to move back and forth greatly, but only needs to move in a small range on one side of the hanger to complete the installation of the drying rods, so that the installation efficiency is higher and more labor-saving.

[0018] The drying rod is provided with a groove, and a strip-shaped hole is arranged at the bottom of the groove. When the rice flour is hung, the rice flour does not completely cover the groove, so that the hot air blown in can flow in the groove, thereby increasing the area of the side of the rice flour that contacts the hot air, and the strip-shaped hole enhances the passing property of the hot air through the drying rod, thereby enhancing the drying effect of the rice flour that contacts the drying rod. The strip-shaped hole is arranged at the groove bottom instead of being arranged on the area of the drying rod that is not provided with the groove, so that the contact area between the drying rod and the rice flour is not too small to cause stress concentration and cause the rice flour to be easily broken.

[0019] The hot air can be blown into the air guide pipe, blown into the drying rod from the end of the drying rod through the air guide pipe, and blown out to the rice flour through the strip-shaped hole on the drying rod, thereby further enhancing the flow property of the hot air at the drying rod, enhancing the drying effect of the area of the rice flour that contacts the drying rod, and enabling the rice flour to be more uniformly dried. The diameter of the drying rod is smaller than the pipe diameter of the air guide pipe, and the flow rate of the hot air increases when the hot air enters the drying rod through the air guide pipe, which is conducive to blowing the hot air from the two ends of the drying rod to a position closer to the center of the drying rod. The air guide pipe serves as a fixing member for fixing the drying rod and a guide member for guiding the hot air, which is a clever structure, one thing with multiple uses, and simplifies the structure.

[0020] When the scissor arms are retracted to the limit position, in each of the two adjacent support members, the thrusting inclined plate thrusts the bearing member in the other support member, thereby driving the air guide pipe to move away from the drying rod, and the drying rod is separated from the air guide pipe. At this time, the two ends of the drying rod are unrestricted, which facilitates the removal of the drying rod and the dried rice flour from the hanger.

[0021] Further, the air guide pipe vertically extends and the bottom surface abuts against the top surface of the support plate. The side of the air guide pipe facing the drying rod is provided with a socket, and the two ends of the drying rod are respectively inserted into the sockets on the two air guide pipes that are symmetrical to each other.

[0024] Further, one end of each insertion section away from the airing section is conical.

[0025] By adopting the technical scheme, the insertion sections can be aligned with the insertion openings when the airing rod is installed, and the insertion sections are guided to be inserted into the insertion openings. The size of the conical section is small, and the effect of increasing the flow rate of airflow is more obvious when the airflow passes through the air duct and enters the inner cavity of the insertion section, so that the airflow can be blown to a position closer to the center of the airing section.

[0026] Further, the bottom of the hanging frame is provided with a collecting mechanism, the collecting mechanism comprises a collecting disc and a pushing member, the collecting disc is located at the bottom of the hanging frame and is used for collecting the rice powder falling from the airing rod, and the pushing member is slidingly installed on the hanging frame and is connected with the connecting rod located at the front end of the scissor arm, so that the pushing member can be moved backward when the scissor arm is retracted backward, and the pushing member can push the rice powder collected in the collecting disc to the rear end of the collecting disc.

[0027] By adopting the technical scheme, the collecting disc can collect the rice powder falling in the drying process due to various reasons, and the pushing member can push the rice powder falling on the collecting disc to the rear end of the collecting disc, so that the falling rice powder can be collected in a centralized manner.

[0028] Further, the collecting disc comprises a fixed disc section and a movable disc section, the fixed disc section is fixedly connected to the bottom of the hanging frame, a space is arranged between the fixed disc section and the bottom surface of the drying room, the rear end of the fixed disc section is provided with an accommodating opening penetrating in the up-down direction, and the movable disc section is a box body structure with an open top end, the movable disc section can be adaptively placed below the accommodating opening by penetrating through the accommodating opening, and the movable disc section can also slide in the front-rear direction below the accommodating opening.

The locking hook 191 is opposite to the above-mentioned locking hole 141 in front and behind, the width dimension of the above-mentioned locking hole 141 in the up-down direction is greater than the maximum width dimension of the locking hook 191 and the locking rod 19 in the up-down direction, the top end of the locking hook 191 is higher than the top hole wall of the locking hole 141, and the bottom end is lower than the top hole wall of the locking hole 141.

[0085] During the process of moving forward of the movable disc segment 14, the top hole wall of the locking hole 141 pushes the locking hook 191 downward through the slope on the locking hook 191, so that the rear side wall plate of the movable disc segment 14 is clamped on the front side of the locking hook 191 to lock the movable disc segment 14 at the position. During the process of the scissor arm elongation and the forward movement of the pushing piece, the pushing block 16 moves to the movable column 10 and pushes the movable column 10 downward through the hemispherical part on the top of the movable column 10, drives the locking hook 191 to move downward, so that the locking hole 141 and the locking hook 191 correspond to each other in the up-down direction, and the movable disc segment 14 is pushed to the initial position under the action of the elastic piece 17.

[0086] As shown in Figure 1 The air guide mechanism comprises air guide plates 3 and a lifting driving mechanism. The air guide plates 3 are provided with four pieces, and each of the left and right sides of each hanger 1 is provided with an air guide plate 3. The air guide plates 3 extend in the front-rear direction and are inclined downward from top to bottom towards the corresponding hanger 1. The two air guide plates 3 located between the two groups of hangers 1 are connected into an integral structure. Each air guide plate 3 is slidingly installed in the drying room 2 in the up-down direction through two guide rods 20 on the front and rear sides.

[0087] The lifting driving mechanism comprises a transmission motor and three transmission lead screws 21. The transmission motor is installed on the top of the drying room 2. The three transmission lead screws 21 all extend in the up-down direction and are all rotationally installed in the drying room 2. The two air guide plates 3 on the left and right sides are respectively in screw transmission connection with the two transmission lead screws 21, and the two air guide plates 3 in the middle which form an integral structure are in screw transmission connection with the other transmission lead screw 21.

[0088] The transmission lead screw 21 in the middle and the transmission lead screws 21 on the two sides are opposite in screw rotation direction. The transmission motor is in transmission connection with the transmission lead screw 21 in the middle. The transmission lead screw 21 in the middle is in transmission connection with the transmission lead screws 21 on the two sides through two belt transmission assemblies, so as to drive the transmission lead screws 21 on the two sides to rotate through the two belt transmission assemblies when the transmission motor drives the transmission lead screw 21 in the middle to rotate. The three lead screws rotate in the same direction, but the transmission lead screw 21 in the middle and the transmission lead screws 21 on the two sides are different in screw rotation direction, so the up-down movement directions of the two air guide plates 3 in the middle and the two air guide plates 3 on the two sides are different. The transmission motor and the belt transmission assemblies are conventional settings and are not shown in the figure.

[0089] In the initial state, the two middle air deflectors 3 are located at the top of the transmission screw rod 21, and the two air deflectors on both sides are located at the bottom of the transmission screw rod 21. After the transmission motor is started, the transmission screw rod 21 drives the two middle air deflectors 3 to move from top to bottom, and the two air deflectors on both sides move from bottom to top. When the two middle air deflectors 3 move to the bottom of the transmission screw rod 21, the transmission motor starts to reverse to drive the air deflectors 3 to move in the opposite direction. This cycle continues, so that the hot air blown by the hot air system at the top is guided to the rice flour from the side of the rice flour during the drying process, thereby enhancing the drying effect of the rice flour. The two middle air deflectors 3 and the two air deflectors on both sides are staggered up and down, so as to avoid the air flow on both sides of the rice flour from colliding and causing the rice flour to shake, thereby avoiding the risk of the rice flour sticking together or breaking.

[0090] The air deflector mechanism starts to operate after the rice flour is dried for a certain period of time and the shape can be kept fixed, thereby avoiding the hot air from being blown to the rice flour from the side of the rice flour when the rice flour is in a wet and slippery state.

[0091] In the use process of the present application, the scissors arm is in a contracted state at the beginning, at this time, the interval between the adjacent front and rear supporting members 6 is relatively close, and the installation of the drying rod 15 may cause the rice flour to stick together. Therefore, the scissors arm is first controlled to be initially expanded by a distance, so that the interval between the adjacent front and rear supporting members 6 is maintained at an appropriate distance, and then the drying rod 15 with rice flour is installed on the hanging rack 1. Before installation, the operator pushes the movable disc segment 14 forward with his foot, so that the locking hook 191 is inserted into the locking hole 141 to lock the movable disc segment 14, and at the same time, the space at the rear end of the hanging rack 1 is left out, so that the operator can stand at the accommodation opening to install the drying rod 15.

[0092] The operator installs the drying rod 15 between the two supporting members 6 on the left and right from front to back. When installing the drying rod 15, one end of the drying rod 15 is first inserted into the socket on the air guide pipe 602 on the corresponding side, and then the drying rod 15 pushes the air guide pipe 602 on the side to move outward, so that the other end of the drying rod 15 moves to the side of the air guide pipe 602 on the other side which is provided with a socket, and the other end of the drying rod 15 is inserted into the socket on the corresponding side of the air guide pipe 602, thereby completing the installation of the drying rod 15.

[0093] After the drying rod 15 is installed, the scissors arm is driven to stretch forward, and in the stretching process, the drying rods 15 with rice flour are gradually separated from front to back, and since the upper drying rods 15 are connected to the supporting members 6 on the connecting rod two 4 and the lower drying rods 15 are connected to the supporting members 6 on the connecting rod one 5, the rice flour on the upper and lower sides will automatically stagger, so that the air blown by the hot air system can be directly blown from top to bottom to the rice flour on the upper and lower layers, thereby making the drying of the rice flour on the upper and lower layers more uniform.

[0094] Meanwhile, when the scissors arm is just stretched out, the pushing block 16 is driven to move forward to pass above the movable column 10, and the movable column 10 is pressed downward, and the locking hook 191 is driven to move downward, and the locking hook 191 moves downward to correspond to the locking hole 141 in the up-down direction, and the movable disc segment 14 is driven to move backward to reset under the action of the elastic member 17.

[0095] After the drying room 2 is closed, the rice flour is dried, and when the rice flour is dried to a certain degree, the lifting driving mechanism drives the air deflector 3 to reciprocate up and down, and the hot air system blows the wind from the side of the rice flour to the rice flour, and the drying effect on the rice flour is further strengthened.

[0096] In the drying process, since the recess 153 is arranged on the airing rod 15, and the strip-shaped hole 154 is arranged at the groove bottom of the recess 153, when the hot air blows on the airing rod 15, the hot air can enter the recess 153, and then flows in the recess 153, and contacts the side of the rice flour which faces the airing rod 15, and the drying effect on the side of the rice flour which faces the airing rod 15 is improved. The hot air which blows into the air guide pipe 602 from top to bottom can enter the inner cavity of the airing rod 15 from the two ends of the airing rod 15, and then blows out from the strip-shaped hole 154 to the rice flour, and the drying effect on the side of the rice flour which faces the airing rod 15 is further improved, and the rice flour is more evenly dried.

[0097] After the drying is completed, the scissors arm is driven to contract to the limit position, and in the process, the pushing inclined plate 607 on the supporting member 6 pushes the vertical rod in the bearing pushing member 606, and drives the air guide pipe 602 to move away from the other air guide pipe 602 which is opposite to the air guide pipe 602, so that the two ends of the airing rod 15 are separated from the air guide pipe 602 and fall on the supporting plate 603. The pushing rod 22 can push the airing rod 15 out of the air guide pipe 602 when the airing rod 15 is synchronously moved by the air guide pipe 602, so that the airing rod 15 can be separated from the air guide pipe 602. After the airing rod 15 is separated from the air guide pipe 602, the airing rod 15 and the rice flour which is hung on the airing rod 15 can be taken off from the hanging frame 1, and the drying process is completed.

[0098] In the process of the scissors arm contraction, the pushing block 16 is driven to move backward, and the pushing block 16 pushes the rice flour which falls in the fixed disc segment 11 during the airing process backward, and finally all the rice flour is pushed into the movable disc segment 14, and at this time, the operator can take out the movable disc segment 14 from the containing opening, and pour the collected broken rice flour into the special collecting box, and the broken rice flour can be repeatedly processed to make other products, and the waste is avoided.

[0099] The present application can make the rice flour on the upper and lower layers in the drying room 2 be more evenly dried, and can make the rice flour on the same airing rod be more evenly dried, and the quality of the rice flour is ensured. The present application can collect the broken rice flour, and the waste is avoided.

[0100] In the embodiment, the airing rod 15 is of sectional structure, comprising an airing section 151 and a plug-in section 152. In other embodiments, the airing rod 15 can be made of integral structure, in which case more attention should be paid to the cleaning of the airing rod 15 to ensure that the dead corners are cleaned.

[0101] In the embodiment, the bottom end of the first connecting rod 5 and the top end of the second connecting rod 4 are connected with the support 6, and the airing rod 15 is connected between the two left and right support 6. In other embodiments, the bottom end of the first connecting rod 5 is vertically connected with a support plate, the top of the support plate is provided with a groove 153-1, and the two ends of the airing rod 15 between the two first connecting rods 5 are arranged in the groove 153-1 on the left and right support plates, and the top end of the second connecting rod 4 is provided with a groove 153-2, and the two ends of the airing rod 15 between the two second connecting rods 4 are arranged in the groove 153-2 on the left and right second connecting rods 4.

[0102] In the embodiment, the first connecting rod 5 is an elastic telescopic rod, and the top end of the first connecting rod 5 is connected to the lower hinge shaft I in a sleeved manner. In other embodiments, the first connecting rod 5 is a common straight rod that cannot be telescopic, the top of the first connecting rod 5 is provided with a vertical long hole, the length of the long hole is greater than the interval between the two hinge shafts I in the scissors arm when it is contracted to the limit position, and the first connecting rod 5 is sleeved outside the two hinge shafts I through the long hole, thereby being connected with the hinge shaft I.
