Description

Technical Field

[0001] The invention belongs to the field of glutinous rice lotus root production equipment, and in particular relates to a preparation device and a preservation method for honey lotus root. Background Art

[0002] Glutinous rice lotus root is a delicacy in the Jiangnan region that can be used as a dish or a snack. It not only has multiple nutritional values ​​such as protein and vitamin C, but also has the effects of moistening the lungs and relieving coughs, replenishing the middle and strengthening qi, and relieving fatigue. When making glutinous rice lotus root, the glutinous rice needs to be fully soaked and then stuffed into the lotus root holes.

[0003] The existing publication number CN114451570B discloses a filling device for processing glutinous rice and lotus root, which includes a working box body, a conveyor belt is arranged inside the working box body, and the conveyor belts are extended to the outside to facilitate the loading and unloading of lotus root segments. A temporary storage component for temporarily fixing the lotus root segments is also fixed on the belt surface of the conveyor belt, a fixed seat is arranged on the rear side of the input end of the conveyor belt, a servo motor 1 is fixedly connected to the top surface of the fixed seat by screws, and the output end of the servo motor 1 is fixedly connected to the input end of the conveyor belt, a glutinous rice storage tank is also fixed on the top surface of the working box body, a rice injection tube is slidably connected to the bottom end of the glutinous rice storage tank, a servo motor 2 is fixed to the middle part of the outer top surface of the glutinous rice storage tank by screws, a rotating rod is fixed to the output end of the servo motor 2, and a stirring paddle is fixed to the upper outer wall of the rotating rod. The device has stable operation, a high degree of filling automation, and good compactness of the glutinous rice after filling, thereby providing a certain guarantee for the beauty of the glutinous rice and lotus root.

[0004] The existing device also has the following deficiencies:

[0005] 1. The lotus root is fixed when the existing device is filling glutinous rice. Since the lotus root holes are of different sizes and the flow rate of glutinous rice is relatively fixed, the tightness of the glutinous rice in the large lotus root hole and the small lotus root hole is inconsistent after the filling is completed, which affects the taste of the finished product.

[0006] 2. When the existing device is filling glutinous rice, the glutinous rice is directly squeezed into the lotus root segment by rotating the auger. During the squeezing, the glutinous rice grains above the lotus root hole will be squeezed into the lotus root hole. After filling, the glutinous rice has good compactness. However, during the squeezing, the glutinous rice grains above the lotus root meat will exert greater pressure on the lotus root meat, which will cause the glutinous rice grains to be embedded in the lotus root meat or even break the lotus root, affecting the integrity and taste of the finished product.

[0007] 3. After the glutinous rice filling is completed, there are usually residual glutinous rice grains on the top of the lotus root. The existing device lacks a device for cleaning the residual glutinous rice grains, which requires manual cleaning and has low work efficiency.

[0008] 4. Honey lotus root is a cooked cereal product and is currently sold on a freshly made basis. It cannot be stored for a long time. Also, since syrup is applied to the surface of the honey lotus root, improper storage can easily cause the sugar to become sour and the glutinous rice to deteriorate. For these reasons, the honey lotus root has become a seasonal product and cannot meet the demand for consumption all year round. Summary of the invention

[0009] The purpose of the present invention is to provide a preparation device and preservation method of honey lotus root in view of the problems raised in the above background technology.

[0010] To achieve the above object, the present invention adopts the following technical scheme: a preparation device for honey lotus root, comprising:

[0015] Furthermore, the rotating component includes a mounting plate fixed on the supporting column, a mounting rod fixed on the mounting plate, a second column gear meshing with the first column gear fixed on the mounting rod, a second hydraulic telescopic rod fixed on the mounting plate, an L-shaped plate fixed on the second hydraulic telescopic rod, and a rack meshing with the second column gear fixed on the L-shaped plate.

[0016] Furthermore, the vibration component includes a wire reel fixed on the mounting rod, a rope is wound around the wire reel, and one end of the rope away from the wire reel is fixed on the clamp.

[0017] Furthermore, a cleaning assembly is provided on the support plate, and the cleaning assembly includes a vertical plate fixed on the support plate, a scraper is provided at the bottom end of the vertical plate, and the scraper includes a first rotating shaft rotatably connected to the bottom end of the vertical plate, two connecting plates are rotatably connected to the first rotating shaft, and a second rotating shaft is rotatably connected to the connecting plate, and rotating rollers are fixed on the first rotating shaft and the second rotating shaft, and rubber plates are sleeved on the two rotating rollers.

[0018] Furthermore, a ratchet gear is fixed on the first rotating shaft, and a ratchet pawl cooperating with the ratchet gear is provided on the vertical plate.

[0019] The present invention also provides a method for preserving honey lotus root, comprising the following steps:

[0020] S1. After the glutinous rice is filled into the lotus root hole, an electric fan is used to blow air at a speed of 1420 rpm for 2 hours;

[0021] S2. Use a 5mm thick, four-sided breathable corrugated cardboard box for packing. When packing, stack the cereal cooked food products honey lotus root crosswise for sealed packaging;

[0022] S3. Place the sealed finished product in a -19.3°C cold room for quick freezing for 4 hours and then adjust the cold room temperature to -18.6°C for long-term storage for one year without adjusting the cold room temperature during this period;

[0023] S4, taking out the glutinous rice lotus root stored for one year from the refrigerator and placing it in a pot, and adding 19° C. tap water into the pot to thaw the honey lotus root;

[0024] S5. Put the thawed water directly into a fire, add sugar and rock sugar and cook until done to achieve the desired effect.

[0025] Compared with the prior art, the advantages of the present invention are:

[0026] 1. The present invention sets a rotating component. When the glutinous rice is unloaded, the second hydraulic telescopic rod drives the rack to move back and forth, thereby driving the second column gear and the first column gear to rotate back and forth, and finally realizing the reciprocating rotation of the lotus root. The glutinous rice above the small lotus root hole can be made to enter the large lotus root hole, so that the tightness of the glutinous rice in the large and small lotus root holes is consistent after the glutinous rice filling is completed, thereby improving the taste of the finished product.

[0027] 2. The present invention sets a vibration component. When the second column gear reciprocates, it drives the reel to rotate reciprocally. Under the action of the rope, the clamp is driven to move up and down to produce a vibration effect, so that the glutinous rice in the lotus root hole is more compact. Compared with the prior art, this method will not damage the lotus root, thereby ensuring the integrity and taste of the finished product.

[0028] 3. The present invention provides a cleaning component, and when the lotus root filled with glutinous rice passes under the scraper, the scraper automatically cleans the residual glutinous rice above the lotus root, thereby saving the time of manual cleaning and improving work efficiency.

[0029] 4. The present invention provides a ratchet gear and a pawl. When the lotus root passes under the scraper, it pushes the first rotating shaft, the second rotating shaft, the connecting plate and the rubber plate to rotate counterclockwise around the axis of the first rotating shaft, and there is no relative rotation between the first rotating shaft, the connecting plate and the rubber plate. After the lotus root moves out from under the scraper, the second rotating shaft, the connecting plate and the rubber plate rotate clockwise around the first rotating shaft under the action of gravity. At this time, the pawl and the ratchet gear are stuck, and the first rotating shaft drives the rubber plate and the connecting plate to rotate relative to each other, so that the rubber plate can clean the residual glutinous rice at different positions each time, thereby improving the cleaning effect.

[0030] 5. The preservation method provided by the present invention preserves the honey lotus root through specific cold wind, specific packaging and specific refrigerator temperature. It has been verified through experiments that the cereal cooked food products can achieve the optimal preservation time, so that the honey lotus root, which is a seasonal product, can meet the needs of the public in any season of the year.

[0045] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0046] like Figure 1-Figure 7 As shown, a preparation device for honey lotus root comprises:

[0047] Conveyor belt 1, four support rods 11 are fixed above the conveyor belt 1, a support plate 12 is fixed on the top of the support rod 11, a lower hopper 13 is fixed on the support plate 12, a material guide pipe 14 is rotatably connected to the discharge port of the lower hopper 13, and a solenoid valve is provided on the material guide pipe 14. After the lotus root is transported to the bottom of the material guide pipe 14, the conveyor belt 1 stops running and the solenoid valve automatically opens. After the unloading is completed, the solenoid valve automatically closes the conveyor belt 1 and continues to run. The material guide pipe 14 extends to the bottom of the support plate 12. A collecting trough 15 is provided under the conveyor belt 1. A plurality of evenly distributed fixed components are provided on the surface of the conveyor belt 1. When working, the fully soaked glutinous rice is placed in the lower hopper 13, and then the washed lotus root is cut off from one end, the cut lotus root is fixed in the clamp 33, and a collecting container is placed at the end of the collecting trough 15.

[0048] A material unloading component is provided below the support plate 12, and the material unloading component includes a first hydraulic telescopic rod 21 fixed on the support plate 12. When the lotus root is transported to the bottom of the guide tube 14, the first hydraulic telescopic rod 21 automatically extends, and the first hydraulic telescopic rod 21 automatically shortens after unloading is completed. A supporting ring 22 is fixed to the output end of the first hydraulic telescopic rod 21, and a bellows 23 is rotatably connected to the supporting ring 22. The top of the bellows 23 is rotatably connected to the guide tube 14, and an annular airbag 24 is fixed to the bottom end of the bellows 23. The air inlet of the airbag 24 is connected to an air pump. When the lotus root is transported to the bottom of the guide tube 14, the first hydraulic telescopic rod 21 automatically extends, and then the air pump inflates the airbag 24. After unloading is completed, the air pump extracts the gas in the airbag 24, and then the first hydraulic telescopic rod 21 automatically shortens.

[0049] During specific operation, after the lotus root is transported to the bottom of the guide pipe 14, the conveyor belt 1 stops running and the first hydraulic telescopic rod 21 automatically extends. The extension of the first hydraulic telescopic rod 21 drives the supporting ring 22 and the airbag 24 to move downward, and then the air pump inflates the airbag 24 to wrap the top of the lotus root, and then the solenoid valve automatically opens to start unloading. After unloading is completed, the solenoid valve automatically closes, and the air pump extracts the gas in the airbag 34, and then the first hydraulic telescopic rod 21 shortens to separate the lotus root from the airbag 34.

[0050] The fixing assembly includes a first column gear 31 arranged above the conveyor belt 1, a through hole 311 is opened in the center of the first column gear 31, an annular groove 312 is opened on the lower surface of the first column gear 31, a plurality of support columns 32 are slidably connected in the annular groove 312, the cross-section of the annular groove 312 is T-shaped, a limiting plate is fixed to the top of the support column 32, the bottom end of the support column 32 is fixed on the conveyor belt 1, a clamp 33 is slidably connected in the through hole 311, the clamp 33 adopts the existing technology and is not described here, a slide rail is fixed on the side wall of the clamp 33, a slide groove adapted to the slide rail is opened on the side wall of the through hole 311, an elastic member 34 is provided below the clamp 33, and the fixing assembly also includes a rotating component and a vibrating component.

[0051] The elastic member 34 includes a sleeve 341 fixed on the conveyor belt 1, a piston plate 342 is slidably connected inside the sleeve 341, a piston rod 343 is fixed on the piston plate 342, the top end of the piston rod 343 passes through the sleeve 341 and is fixed on the clamp 33, a spring 344 is sleeved on the piston rod 343, and the spring 344 is located in the sleeve 341 and above the piston plate 342.

[0052] The rotating component includes a mounting plate 41 fixed on the support column 32, a mounting rod 42 is fixed on the mounting plate 41, a second column gear 43 meshing with the first column gear 31 is fixed on the mounting rod 42, a second hydraulic telescopic rod 44 is fixed on the mounting plate 41, when the solenoid valve is turned on, the second hydraulic telescopic rod 44 automatically starts to reciprocate and telescope, an L-shaped plate 45 is fixed on the second hydraulic telescopic rod 44, and a rack 46 meshing with the second column gear 43 is fixed on the L-shaped plate 45.

[0053] The vibration component includes a wire reel 51 fixed on the mounting rod 42 . A rope 52 is wound around the wire reel 51 . One end of the rope 52 away from the wire reel 51 is fixed to the clamp 33 .

[0054] During specific operation, after the solenoid valve is turned on, the second hydraulic telescopic rod 44 automatically starts to reciprocate and retract and drives the L-shaped plate 45 to reciprocate, thereby driving the rack 46 to reciprocate, and the reciprocating movement of the rack 46 drives the second column gear 43 to reciprocate, thereby driving the first column gear 31 and the clamp 33 to reciprocate, and finally realizes the reciprocating rotation of the lotus root. The reciprocating rotation of the lotus root can make the glutinous rice above the small lotus root hole enter the large lotus root hole;

[0055] When the second column gear 43 rotates, it drives the mounting rod 42 and the wire reel 51 to rotate reciprocatingly. When the wire reel 51 rolls up the rope 52, it pulls the clamp 33 upward, thereby driving the piston rod 343 to move upward and compressing the spring 344. When the wire reel 51 releases the rope 52, the piston rod 343 drives the clamp 33 to move downward under the elastic force of the spring 344. In this way, the clamp 33 and the lotus root can be reciprocated up and down. The reciprocating up and down movement of the lotus root causes the lotus root to vibrate, thereby making the glutinous rice in the lotus root hole tighter.

[0056] A cleaning assembly is provided on the support plate 12, and the cleaning assembly includes a vertical plate 61 fixed on the support plate 12, a scraper 62 is provided at the bottom end of the vertical plate 61, the scraper 62 includes a first rotating shaft 621 rotatably connected to the bottom end of the vertical plate 61, two connecting plates 622 are rotatably connected to the first rotating shaft 621, and a second rotating shaft 623 is rotatably connected to the connecting plate 622, rotating rollers 624 are fixed on the first rotating shaft 621 and the second rotating shaft 623, and rubber plates 625 are sleeved on the two rotating rollers 624.

[0057] A ratchet gear 6211 is fixed on the first rotating shaft 621 , and a ratchet pawl 611 cooperating with the ratchet gear 6211 is provided on the vertical plate 61 .

[0058] During specific operation, when the lotus root passes under the scraper 62, it pushes the first rotating shaft 621, the second rotating shaft 623, the connecting plate 622 and the rubber plate 625 to rotate counterclockwise around the axis of the first rotating shaft 621, and there is no relative rotation between the first rotating shaft 621, the connecting plate 622 and the rubber plate 625. After the lotus root moves out from under the scraper 62, the second rotating shaft 623, the connecting plate 622 and the rubber plate 625 rotate clockwise around the first rotating shaft 621 under the action of gravity. At this time, the pawl 611 and the ratchet gear 6211 are stuck, and the first rotating shaft 621 drives the rubber plate 625 and the connecting plate 622 to rotate relative to each other, so that the rubber plate 625 cleans the residual glutinous rice at different positions each time.

[0059] like Figure 8 As shown, the present invention also provides a method for preserving honey lotus root, comprising the following steps:

[0060] S1. After the glutinous rice is filled into the lotus root hole, an electric fan is used to blow air at a speed of 1420 rpm for 2 hours;

[0061] S2. Use a 5mm thick, four-sided breathable corrugated cardboard box for packing. When packing, stack the cereal cooked food products honey lotus root crosswise for sealed packaging;

[0062] S3. Place the sealed finished product in a -19.3°C cold room for quick freezing for 4 hours and then adjust the cold room temperature to -18.6°C for long-term storage for one year without adjusting the cold room temperature during this period;

[0063] S4, taking out the glutinous rice lotus root stored for one year from the refrigerator and placing it in a pot, and adding 19° C. tap water into the pot to thaw the honey lotus root;

[0064] S5. Boil the thawed water directly on fire, add white sugar and rock sugar and cook until done to achieve the desired effect (the thawed water cannot be replaced, as it contains a large amount of lotus root powder, which helps thicken the soup).

[0065] The working principle of the present invention is as follows:

[0066] During operation, the fully soaked glutinous rice is placed in the lower hopper 13, and then the cleaned lotus root is cut from one end, the cut lotus root is fixed in the clamp 33, and a collection container is placed at the end of the collecting tank 15, and then the conveyor belt 1 is turned on;

[0067] The conveyor belt 1 drives the lotus root to move toward the end of the conveyor belt 1. When the lotus root is transported to the bottom of the guide pipe 14, the conveyor belt 1 stops running and the first hydraulic telescopic rod 21 automatically extends. The extension of the first hydraulic telescopic rod 21 drives the supporting ring 22 and the air bag 24 to move downward. Then the air pump inflates the air bag 24 to wrap the top of the lotus root, and then the solenoid valve automatically opens to start unloading.

[0068] After the solenoid valve is turned on, the second hydraulic telescopic rod 44 automatically starts to reciprocate and retract and drives the L-shaped plate 45 to reciprocate, thereby driving the rack 46 to reciprocate. The reciprocating movement of the rack 46 drives the second column gear 43 to reciprocate, thereby driving the first column gear 31 and the clamp 33 to reciprocate, and finally realizes the reciprocating rotation of the lotus root. The reciprocating rotation of the lotus root can make the glutinous rice above the small lotus root hole enter the large lotus root hole, so as to achieve the consistency of the tightness of the glutinous rice in the large and small lotus root holes after the glutinous rice filling is completed, thereby improving the taste of the finished product;

[0069] When the second column gear 43 rotates, it drives the mounting rod 42 and the wire reel 51 to rotate reciprocally. When the wire reel 51 rolls up the rope 52, it pulls the clamp 33 upward, thereby driving the piston rod 343 to move upward and compressing the spring 344. When the wire reel 51 releases the rope 52, the piston rod 343 drives the clamp 33 to move downward under the elastic force of the spring 344. In this way, the clamp 33 and the lotus root can be reciprocated up and down. The lotus root is vibrated by the reciprocating up and down movement, so that the glutinous rice in the lotus root hole is more compact. In addition, this method will not damage the lotus root, thereby ensuring the completion and taste of the finished product.

[0070] After the glutinous rice is filled, the solenoid valve is automatically closed, the second hydraulic telescopic rod 44 stops moving, and the air pump extracts the gas in the airbag 34. Then the first hydraulic telescopic rod 21 is shortened to separate the lotus root from the airbag 34, and the conveyor belt 1 continues to operate to drive the lotus root filled with glutinous rice to move to the end of the conveyor belt 1.

[0071] When the lotus root passes under the scraper 62, it pushes the first rotating shaft 621, the second rotating shaft 623, the connecting plate 622 and the rubber plate 625 to rotate counterclockwise around the axis of the first rotating shaft 621, and there is no relative rotation between the first rotating shaft 621, the connecting plate 622 and the rubber plate 625. After the lotus root moves out from under the scraper 62, the second rotating shaft 623, the connecting plate 622 and the rubber plate 625 rotate clockwise around the first rotating shaft 621 under the action of gravity. At this time, the pawl 611 and the ratchet gear 6211 are stuck, and the first rotating shaft 621 drives the rubber plate 625 and the connecting plate 622 to rotate relative to each other, so that the rubber plate 625 cleans the residual glutinous rice at different positions each time, and the residual glutinous rice is automatically cleaned by the scraper 62, which saves the time of manual cleaning and improves the work efficiency. The design of the ratchet gear 6211 and the pawl 611 improves the cleaning effect.

[0072] When the lotus root is transported to the outside of the support plate 12, the lotus root filled with glutinous rice is taken off. As the conveyor belt 1 runs, the residual glutinous rice that is cleaned and falls on the conveyor belt 1 eventually falls from the collecting trough 15 into the collecting container for further use, thus avoiding waste.

[0073] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
