Description

Technical Field

[0001] The invention relates to the technical field of dough kneading equipment, and in particular to a continuous automatic dough kneading equipment and a dough kneading process. Background Art

[0002] Kneading dough is an important step in making pasta, which is to add water to the flour and stir or knead it to make it sticky. The flour and water are fully combined to form a smooth dough. This process helps to activate the gluten in the flour, making the dough more elastic and tough, so that it can be better shaped, fermented and cooked in the subsequent production. Since the process of kneading dough is the process of kneading flour and water, the process is relatively laborious to implement. Therefore, for pasta production companies, in order to reduce the labor intensity of employees and improve production results, dough kneading equipment is usually used for dough kneading;

[0003] As a type of dough mixer, a spiral dough mixer uses a motor as a power source to drive the spiral blades to rotate and drive the flour and water in the dough mixing box to mix with each other, thereby achieving the purpose of dough mixing. At present, in order to improve the taste of the dough, the dough is kneaded twice. At the same time, in order to ensure the continuity of the dough mixing and improve the dough mixing efficiency, the first and second dough mixing can be carried out simultaneously. For example, the authorization announcement number CN118104694 B discloses a continuous automatic dough mixing process and dough mixing equipment. However, in the prior art, when the second dough mixing is carried out after the first dough mixing, the position of the dough of the first dough mixing needs to be changed. When changing the position, the machine is usually stopped for operation, and the weight of the dough is used to leave the position of the first dough mixing, resulting in poor continuity during operation. At the same time, because the dough is sticky, it is easy for the dough to adhere to the dough mixing box due to its stickiness and cannot be smoothly changed under the action of gravity. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

[0011] The beneficial effects of the continuous automatic dough kneading device of the present invention are as follows: the spiral blades are driven to rotate by the dough kneading motor, and when the dough kneading is completed once inside the dough kneading box corresponding to the front of the partition, the electric push rod drives the two plug plates to move outward, so that the internal space of the dough kneading box corresponding to the front of the partition is communicated with the internal space of the dough kneading box corresponding to the rear of the partition, and the dough that has been kneaded once can be transported to the interior of the dough kneading box corresponding to the rear of the partition for secondary kneading under the conveying action of the spiral blades. During the secondary kneading process, an appropriate amount of new flour and water can be poured into the interior of the dough kneading box corresponding to the front of the partition for primary kneading. Compared with the prior art, the spiral blades can knead the flour and water in front of the partition once and the flour and water in the rear of the partition once when rotating. The dough after kneading is kneaded for the second time, so that the first kneading and the second kneading are carried out synchronously. At the same time, there is no need to stop the machine for operation when the dough after kneading is replaced. In addition, the spiral blades are used to realize the conveying and kneading effect of flour and water. The taking out of the dough after kneading for the second time is also achieved by the spiral blades, which makes it convenient to take out the dough after kneading for the second time, improves the continuity during kneading, and makes it possible to change the position of the dough after kneading for the first time without stopping the machine, which solves the problem that the prior art usually stops the machine for operation when changing the position, and uses the weight of the dough to leave the position of the first kneading, resulting in poor continuity during operation. At the same time, the prior art is prone to the problem that the dough sticks to the kneading box due to its stickiness and cannot be smoothly replaced under the action of gravity.

[0012] Considering that after the dough mixer is used, for hygiene reasons, it is necessary to clean the residues adhering to the inner wall of the dough mixer to ensure the cleanliness of the inner wall of the dough mixer, the prior art scrapes the residues on the inner wall of the dough mixer by moving a scraper after the dough is kneaded, but the spiral blades provide power for flour and water to knead the dough and also adhere to the residues. The residues on the spiral blades need to be cleaned manually, which increases the labor intensity when cleaning the residues. Therefore, a continuous automatic dough mixer is further improved.

[0013] As a preferred solution of a continuous automatic dough kneading device of the present invention, an electric telescopic rod is fixed at the middle position of the upper wall of the connecting box, a U-shaped mounting bracket is fixed to the upper end of the electric telescopic rod, a moving block is fixed to the lower end of the mounting bracket, a sliding rod and a threaded rod are respectively provided inside the two moving blocks with clearance fit, and connecting plates are fixed to the outsides of the threaded rod and the two ends of the sliding rod corresponding to the side walls of the dough kneading box, the threaded rod is rotatably connected to the corresponding connecting plate through a bearing, the sliding rod is fixedly connected to the corresponding connecting plate, a driving motor is fixed to the front wall of the side plate in front of the threaded rod, and the power output shaft of the driving motor is fixedly connected.

[0014] As a preferred solution of a continuous automatic dough kneading device of the present invention, duckbill nozzles are fixed on both the front and rear sides of the lower wall of the connecting box; an electromagnet is fixed on the lower wall of the connecting box at the position of the cleaning box corresponding to the lower wall of the connecting box, and a protrusion is fixed on the lower wall of the electromagnet, which is plugged into the interior of the corresponding cleaning box; semi-threaded bolts are penetrated on both the upper and lower sides of the scraper, and the semi-threaded bolts are threadedly connected to the cleaning box, and an elastic part is arranged on the interior of the cleaning box at the position of the scraper corresponding to the cleaning box, and the two ends of the elastic part are respectively abutted against the scraper and the cleaning box.

[0015] Another beneficial effect of the continuous automatic dough kneading device of the present invention is that the corresponding position of the spiral blade is located inside the installation groove by moving the cleaning box. When the cleaning box is separated from the magnetic adsorption from the electromagnet, the upper side of the cleaning box is matched with the gap between the dough kneading box and the dough kneading box, so that when the spiral blade rotates, the cleaning box is driven to move. When the cleaning box moves, the cleaning box can clean the corresponding position of the inner wall of the dough kneading box, and at the same time, clean the residue on the surface of the spiral blade. Since the scraper bar is also in contact with the inner wall of the dough kneading box, the scraper bar can scrape the residue on the corresponding position of the inner wall of the dough kneading box. At the same time, since the lower wall of the cleaning box is in contact with the outer peripheral wall of the rotating rod, the cleaning box can also scrape the residue on the outer peripheral wall of the rotating rod. Compared with the prior art, the cleaning box is driven to move by the rotation of the spiral blade, so that the residue on the surface of the spiral blade, the inner wall of the dough kneading box and the outer peripheral wall of the rotating rod can be scraped off, without the need for manual residue cleaning operations, thereby solving the problem that the residue on the spiral blade needs to be cleaned manually, which increases the labor intensity when cleaning the residue.

[0016] After the residues in the dough kneading equipment are cleaned, in order to further improve the cleaning effect, the dough kneading equipment needs to be further cleaned. However, most of the existing technologies use manual injection of water into the dough kneading equipment for cleaning. At the same time, the residual water in the dough kneading equipment after cleaning dries slowly and is easy to breed bacteria. Therefore, a further improvement is made to a continuous automatic dough kneading equipment.

[0017] As a preferred solution of a continuous automatic dough kneading device of the present invention, the lower wall of the water tank is provided with a perforation, a fan is fixed on the water tank corresponding to the lower side of the perforation, a protective net is fixed on the lower wall of the fan, legs are fixed at the four corners of the lower wall of the water tank, a solenoid valve 1 is fixed on the air duct, a solenoid valve 2 is fixed on the delivery pipe at the water outlet of the water pump, and an audible and visual alarm is fixed on the upper wall of the water tank.

[0018] As a preferred solution of a continuous automatic dough kneading device of the present invention, a water inlet pipe is fixed to the upper wall of the water tank on one side of the sound and light alarm, a liquid inlet pipe is fixed to the upper wall of the water tank on one side of the water inlet pipe, a pipe cover is connected to the external thread of the liquid inlet pipe, a stirring motor is fixed at the middle position of the upper wall of the water tank, a mounting rod is fixed on the power output shaft of the stirring motor, and a plurality of stirring rods are evenly fixed to the outer peripheral wall of the mounting rod.

[0019] Another beneficial effect of the continuous automatic dough kneading device of the present invention is: the inner wall of the dough kneading box, the surface of the spiral blades and the outer peripheral wall of the rotating rod are cleaned by utilizing the water pump, and then the airflow generated by the fan is used to carry the heat generated by the heating wire to form a hot air flow that passes through the duckbill nozzle until it acts on the inner wall of the dough kneading box, the surface of the spiral blades and the outer peripheral wall of the rotating rod, and the driving motor is used to drive the duckbill nozzle or move back and forth multiple times for rapid drying, thereby preventing moisture from remaining on the inner wall of the dough kneading box, the surface of the spiral blades and the outer peripheral wall of the rotating rod for a long time. Compared with the prior art, it can realize the cleaning operation inside the dough kneading box without excessive manual intervention, thereby reducing the labor intensity during cleaning. At the same time, the inside of the dough kneading box can also be quickly dried, thereby solving the problem that most of the prior art uses manual injection of water into the dough kneading device for cleaning, and the residual moisture in the dough kneading device after cleaning dries slowly, which is easy to breed bacteria.

[0020] The present invention also provides a dough kneading process of a continuous automatic dough kneading device, which is operated according to the following steps:

[0021] S1. First, check the state of the continuous automatic dough kneading device before kneading, operate the automatic controller to make the dough kneading motor work to drive the rotating rod to rotate, so that the spiral blade rotates;

[0022] S2, when kneading the dough once, pour appropriate amounts of flour and water into the corresponding dough kneading box in front of the partition in sequence, and the spiral blades rotate to mix the flour and water and continuously transport them in the direction of the plug plate;

[0023] S3. After the dough is kneaded once, the automatic controller controls the electric push rod to retract, so that the two side plates drive the two plug plates to move away from each other. Under the action of the driving force generated by the rotation of the spiral blade, the dough that has been kneaded once is pushed to the rear of the partition. Under the action of the spiral blade behind the partition, the dough that has been kneaded once is pushed to the rear end of the dough kneading box. In this way, the dough that has been kneaded once is continuously conveyed to achieve secondary kneading of the dough that has been kneaded once.

[0024] S4. During the operation of S3, when the dough after the first kneading enters the dough kneading box behind the partition, the operation of S2 is executed to realize the continuous and synchronous operation of the first kneading and the second kneading. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0044] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , which is the first embodiment of the present invention, provides a continuous automatic dough kneading device, through the rotation of the spiral blade 109, the flour and water in front of the partition 107 can be synchronously kneaded once and the dough after the first kneading behind the partition 107 can be kneaded twice, and the spiral blade 109 is used to realize the transportation and kneading of flour and water, which is convenient for conveying the dough after the first kneading and the dough after the second kneading. At the same time, there is no need to stop the machine for operation when replacing the dough after the first kneading, thereby achieving the effect of improving the continuity of dough kneading.

[0045] Specifically, the dough kneading mechanism 1 includes a dough kneading box 101, a spiral blade 109 arranged inside the dough kneading box 101 and arranged along the length direction of the dough kneading box 101, a plug plate 111 symmetrically arranged and plugged into the left and right side walls of the dough kneading box 101 and having a clearance fit with the dough kneading box 101, and a box door 106 arranged at the rear of the dough kneading box 101, the bottom of the dough kneading box 101 is adapted to the spiral blade 109, and the lower wall of the plug plate 111 is in contact with the lower wall of the dough kneading box 101 to avoid leakage. The dough kneading box 101 is configured to be divided into a primary dough kneading area in front of the partition 107 and a secondary dough kneading area behind the partition 107 by making the two plug plates 111 contact each other. When the dough after the primary dough kneading is subjected to secondary dough kneading, the two plug plates 111 are moved away from each other, and the dough after the primary dough kneading can be transported to the secondary dough kneading area for secondary dough kneading with the cooperation of the spiral blades 109. The equipment cleaning mechanism 2 provided on the inner side of the dough kneading mechanism 1 includes a hollow I-shaped connecting box 203, a connecting box 203 provided on the connecting box 203, and a connecting box 203 provided on the connecting box 203. The cleaning box 205 is convexly shaped and arranged at the bottom of the front and rear ends, and the scrapers 206 are arranged on the left and right side walls of the cleaning box 205. The above arrangement can drive the cleaning box 205 to move by rotating the spiral blade 109, so as to scrape off the residues on the surface of the spiral blade 109, the inner wall of the dough box 101 and the outer peripheral wall of the rotating rod 114; and the equipment cleaning mechanism 3 is arranged on the left side of the dough mixing mechanism 1, including a water tank 301, a fan 309 arranged on the lower wall of the water tank 301, and a fan 309 arranged above the fan 309 and fixed on the The heating wire 308 inside the water tank 301 and the water pump 303 arranged on the upper wall of the water tank 301, the above arrangement, transports water through the water pump 303, and passes through the duckbill nozzle 203a to act on the surface of the spiral blade 109, the inner wall of the dough box 101 and the outer wall of the rotating rod 114 for flushing. At the same time, during the drying operation, the airflow generated by the fan 309 carries the heat generated by the heating wire 308 to achieve rapid drying of the surface of the spiral blade 109, the inner wall of the dough box 101 and the outer wall of the rotating rod 114.

[0046] Read in detail Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a dough kneading motor 102 is fixed to the front wall of the dough kneading box 101 at the position where the spiral blade 109 is located, and a rotating rod 114 with a circular cross section located inside the dough kneading box 101 is fixed on the power output shaft of the dough kneading motor 102. The rotating rod 114 is fixedly connected to the spiral blade 109. An electric push rod 104 is arranged outside the dough kneading box 101. A gear 113 is arranged below the dough kneading box 101. The front and rear of the gear 113 are meshed and connected with racks 112.

[0047] With the above arrangement, when the dough kneading motor 102 is working, it drives the rotating rod 114 to rotate, causing the spiral blade 109 to rotate, and the corresponding side plate 111a moves through the operation of the electric push rod 104, thereby causing the corresponding rack 112 to move, and with the cooperation of the gear 113, the other rack 112 moves, thereby achieving the effect of making the two plug plates 111 move synchronously outward or inward, thereby achieving the effect that the electric push rod 104 can control the synchronous movement of the two plug plates 111.

[0048] Read in detail Figure 2 As shown, an automatic controller 101a is fixed to the front wall of the dough mixing box 101, which is used to automatically control the electrical appliances in the continuous automatic dough mixing device. The single-chip microcomputer in the automatic controller 101a is pre-implanted with dough mixing, cleaning and cleaning programs. The above method is a prior art and can be achieved by purchasing in the market or customizing. No further details are given here. A plurality of screw sleeves 101b are fixed along the edge of the lower wall of the dough mixing box 101. The internal threads of the screw sleeves 101b are connected to the screw rod 103, and the lower end of the screw rod 103 is fixed to the bottom plate 103a;

[0049] With the above arrangement, when installing the present continuous automatic dough kneading device, the corresponding screw 103 is rotated by operating the bottom plate 103a. Since the screw 103 is threadedly connected to the corresponding screw sleeve 101b, the height of the screw 103 changes when it rotates, which drives the height of the corresponding bottom plates 103a to change, until all the bottom plates 103a are in contact with the ground. At this time, the present continuous automatic dough kneading device is stably connected to the ground, and this method can be used for installation on uneven ground.

[0050] Read in detail Figure 3 As shown, a partition 107 is fixed above the inserting plate 111 corresponding to the inner wall of the dough kneading box 101. The partition 107 and the inserting plate 111 cooperate to divide the interior of the dough kneading box 101 into two parts, so as to facilitate the primary dough kneading and the secondary dough kneading. A convex strip 107a is fixed to the lower wall of the partition 107. A groove 111b adapted to the convex strip 107a is provided on the upper wall of the inserting plate 111 at the position where the convex strip 107a is located. The convex strip 107a is located inside the groove 111b.

[0051] With the above arrangement, when two plug boards 111 that are far away from each other move and approach each other, the convex strip 107a is located inside the groove 111b. The cooperation between the convex strip 107a and the groove 111b can improve the stability of the plug board 111 during use and prevent the plug board 111 from moving backward due to force.

[0052] Read in detail Figure 3 , Figure 4 and Figure 5As shown, a side plate 111a is fixed to the outer side wall of the plug plate 111, and the inner end of the electric push rod 104 is fixedly connected to the corresponding side plate 111a. A fixed plate 101c arranged in an L shape is fixed to the outer end of the electric push rod 104. The fixed plate 101c is fixedly connected to the dough box 101. A guide rod 101f is provided in the internal clearance of the side plate 111a away from the electric push rod 104. The inner end of the guide rod 101f is fixedly connected to the dough box 101. The corresponding side plate 111a can be guided by the guide rod 101f, so that the side plate 111a can only move inward or outward. A round rod 101g is fixed to the lower wall of the dough box 101 inside the gear 113, so that the gear 113 can rotate at a fixed position. The gear 113 is rotatably connected to the round rod 101g through a bearing. The two racks 112 are respectively fixedly connected to the corresponding side plates 111a, so that both racks 112 move outward or inward.

The two plug plates 111 are in contact with the rotating rod 114, so that the two plug plates 111 can also limit the rotating rod 114 to prevent the rotating rod 114 from bending and deforming due to uneven force on the spiral blade 109 when rotating. The rear wall of the dough box 101 is provided with a discharge hole 101 e. After the box door 106 is opened, the dough after the second kneading is discharged from the discharge hole 101e under the action of the spiral blade 109. A limiting sleeve 110 is provided in the discharge hole 101e, which is clearance-matched with the rotating rod 114. The outer portion of the limiting sleeve 110 is fixed with limiting rods 110a in a circumferential array. The outer end of the limiting rod 110a is in contact with the dough kneading box 101. The front of the limiting sleeve 110 is fixed with a limiting ring 114b corresponding to the outer portion of the rotating rod 114, which is used to limit the limiting sleeve 110 to prevent the limiting sleeve 110 from moving toward the spiral blade 109 when in use;

[0054] In the above arrangement, the limiting rod 110a is used to support the limiting sleeve 110, and when the rotating rod 114 rotates, the limiting sleeve 110 can limit the rear end of the rotating rod 114 to avoid deformation of the rotating rod 114 due to uneven force. In addition, in order to ensure the integrity of the dough when the secondary kneading is taken out, the limiting sleeve 110 is detachable. When the secondary kneading dough is taken out, the limiting sleeve 110 is first separated from the rotating rod 114, and before closing the door 106, the limiting sleeve 110 is sleeved on the outside of the rotating rod 114 and then the door 106 is closed.

When the door 106 is open, the block 105 is passed through the groove 101d-1 by operating the handle 108, and then the handle 108 is rotated to prevent the door 106 from rotating. The door 106 can be closed. When the door 106 is closed, the door 106 is in contact with the dough box 101.

[0057] Furthermore, the present continuous automatic dough kneading device does not limit the spiral direction of the spiral blade 109 and the rotation direction of the power output shaft of the dough kneading motor 102. It is only necessary to achieve the state in which the spiral blade 109 can rotate to drive the dough kneaded once and the dough kneaded twice to move backward. At the same time, the two spiral blades 109 shown in the figure have the same pitch and the same diameter. In addition, the cross-section of the bottom of the dough kneading box 101 is an arc-shaped setting that matches the spiral blade 109. Example 2

[0072] This embodiment is the fourth embodiment of the present invention. This embodiment provides a dough kneading process of a continuous automatic dough kneading device, which is operated according to the following steps:

[0073] S1. First, check the state of the continuous automatic dough kneading device before kneading, operate the automatic controller 101a to make the dough kneading motor 102 work to drive the rotating rod 114 to rotate, so that the spiral blade 109 rotates;

[0074] S2, when kneading dough for the first time, appropriate amounts of flour and water are poured into the interior of the dough kneading box 101 corresponding to the front of the partition 107, and the spiral blade 109 rotates to mix the flour and water and continuously transport them in the direction of the insert plate 111;

[0075] S3, after the dough is kneaded once, the automatic controller 101a controls the electric push rod 104 to retract, so that the two side plates 111a drive the two plug plates 111 to move away from each other, and under the driving force generated by the rotation of the spiral blade 109, the dough that has been kneaded once is pushed to the rear of the partition 107, and under the action of the spiral blade 109 behind the partition 107, the dough that has been kneaded once is pushed to the rear end of the dough kneading box 101, so that the dough that has been kneaded once is continuously conveyed to achieve secondary kneading of the dough that has been kneaded once;

[0076] S4, during the operation of S3, when the dough after the first kneading enters the dough kneading box 101 behind the partition 107, the operation of S2 is performed to achieve continuous and synchronous kneading of the first and second kneading;

[0077] S5. After the second dough kneading is completed, the container for holding the dough is placed under the discharge hole 101e. At this time, the operating handle 108 is rotated to drive the connecting rod 108a and the block 105 to rotate, and the block 105 and the through groove 101d-1 are in a horizontal overlapping state, and the box door 106 can be opened. Under the push of the spiral blade 109, the dough after the second dough kneading passes through the discharge hole 101e and falls into the container for holding the dough. In this process, the limiting sleeve 110 will be separated from the rotating rod 114 and fall off. When closing the box door 106, the operating limiting sleeve 110 is located outside the rotating rod 114, and then the box door 106 is closed and the block 105 passes through the through groove 101d-1 and is in the initial state;

[0078] S6, then cyclically executing the operations of S3, S4 and S5 in sequence until the required flour and water are kneaded;

[0079] S7. During cleaning, the automatic controller 101a controls the dough kneading motor 102 to rotate until the spiral blade 109 is at a suitable preset angle, and then the dough kneading motor 102 stops rotating. Then the automatic controller 101a controls the driving motor 207 to drive the threaded rod 207a to rotate, thereby driving the mounting frame 201a, the electric push rod 104, the connecting box 203, and the electromagnet 208 to move until the cleaning box 205 moves to the top of the front end of the spiral blade 109. The automatic controller 101a controls the electric telescopic rod 201 to extend and drive the cleaning box 205 to move downward and make the corresponding position of the spiral blade 109 located in the mounting groove 205a. At this time, the electromagnet 208 of the automatic controller 101a is powered off and loses its magnetism. The automatic controller 101a retracts the electric telescopic rod 201 and drives the connecting box 203 to move upward. Then the automatic controller 101a also controls the dough kneading motor 102 to drive the spiral blade 109 to rotate. The upper side is in clearance with the dough box 101. At this time, the spiral blade 109 rotates and drives the cleaning box 205 to move backward. In this process, the lower side of the cleaning box 205 scrapes the residue on the surface of the spiral blade 109, and the two side walls of the upper side of the cleaning box 205 and the scraping strip 206b scrape the residue on the inner wall of the dough box 101. In the cleaning process, the automatic controller 101a controls the driving motor 207 to make the connecting box 203 move with the cleaning box 205. When the cleaning box 205 moves to the position where the cleaning is finished, the automatic controller 101a extends the electric telescopic rod 201 to drive the electromagnet 208 to descend until the protrusion 208a on the lower wall of the electromagnet 208 is inserted into the interior of the cleaning box 205. The automatic controller 101a then controls the electromagnet 208 to energize to generate magnetic adsorption of the cleaning box 205, and then controls the electric telescopic rod 201 to retract to drive the cleaning box 205 to break contact with the spiral blade 109 to complete the cleaning.

[0080] S8. During the operation of S1-S7, by observing the transparent window 301e, when the liquid level inside the water tank 301 is low, a proper amount of water is added into the water tank 301 through the water inlet pipe 301c, and the automatic controller 101a turns on the power of the heating wire 308 to make the heating wire 308 work, and the heat generated acts on the heat conducting plate 301g to heat the water in the water tank 301. At the same time, the pipe cover 305a is opened to add a proper amount of detergent into the water tank 301, and the automatic controller 101a starts the stirring motor 306 to drive the mounting rod 307 and the stirring rod 307a to rotate. The cleaning agent and water in the water tank 301 are mixed. After the cleaning operation is completed, the automatic controller 101a controls the dough motor 102 and the water pump 303 to work, the electromagnetic valve 2 304a is closed, the electromagnetic valve 1 302a is opened, and the water pump 303 transports the water inside the water tank 301 to the connection box 203, and then acts on the inner wall of the dough box 101, the surface of the spiral blade 109 and the rotating rod 114 through the duckbill nozzle 203a for washing. At the same time, the automatic controller 101a controls the driving motor 207 to drive the connection box 203 to move for single or multiple washings;

[0081] S9. After the flushing is completed, the box door 106 is opened to drain the water inside the dough box 101, the automatic controller 101a controls the water pump 303 to stop working, the fan 309 starts working, the solenoid valve 2 304a is opened, and the solenoid valve 1 302a is closed. At this time, the airflow generated by the fan 309 carries the heat generated by the heating wire 308 into the connecting box 203, and then passes through the duckbill nozzle 203a to act on the inner wall of the dough box 101, the surface of the spiral blade 109 and the rotating rod 114 for drying. At the same time, the automatic controller 101a controls the driving motor 207 to drive the connecting box 203 to move for single or multiple flushing.
