Description

Technical Field

[0001] The utility model belongs to the technical field of maltodextrin cleaning and recycling, in particular to a maltodextrin production cleaning and recycling system. Background Art

[0002] Maltodextrin, also known as water-soluble dextrin and enzymatic dextrin, is a powdered product made from starch through low-level hydrolysis by acid or enzyme method, refining, concentration, sterilization, drying and sieving. It is a low-conversion product of starch, and its molar mass is between starch and starch sugar. It is a novel low-sweetness, low-calorie, high-nutrition food and medicine auxiliary material. Maltodextrin is colorless, odorless, slightly sweet, and is often added to food as an auxiliary material. It can be added as a thickener and filler to candies, milk powder, solid beverages, cakes, nutritional supplements, and various liquid beverages such as coconut milk and peanut almond milk to improve the taste of the product and increase the viscosity.

[0003] Maltodextrin comes in two forms: powder and liquid. When the existing powdered maltodextrin is placed, it will clump due to long-term storage in a stack or the influence of a humid environment, which will affect the subsequent sale or use. Therefore, the agglomerated powdered maltodextrin needs to be cleaned and recycled. The existing structure mostly uses a sieve filter, and then the powder blocks are manually crushed and repackaged. However, the maltodextrin recycled by this method is prone to bacteria, which will affect the health of the consumer. Therefore, a maltodextrin production, cleaning and recycling system is needed to solve the above problems. Utility Model Content

Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0020] As attached Figure 1 shown.

[0021] A maltodextrin production, cleaning and recycling system comprises a feeding tank 1 for conveying materials and a cleaning and recycling device 8 for cleaning and recycling, wherein a circular opening is provided on the surface of the feeding tank 1 to form a feeding port for feeding materials, and a sealing cover 2 is provided on the surface of the circular opening, and a user can pour the maltodextrin to be cleaned into the feeding tank 1 through the feeding port. After pouring a certain amount of maltodextrin, if the user does not need to operate the feeding tank 1 anymore, the sealing cover 2 can be covered on the feeding port; at the same time, since the feeding tank 1 is located at a higher position, the user can install a feeding staircase at the rear end of the feeding tank 1 to facilitate the feeding personnel to go up and down.

[0022] In order to improve the stability of the device, a support frame 4 is installed at the bottom end of the device, and the support frame 4 is symmetrically arranged on the lower surface of the device.

[0023] An intelligent control box is installed at the bottom of the device, and a PLC for realizing intelligent control is installed in the intelligent control box.

[0024] Combination Figure 2 A valve is installed at the bottom end of the feeding tank 1, and the valve is an electromagnetic valve. The electromagnetic valve is installed at the output end of the PLC. A circular through hole is arranged on the top surface of the cleaning recovery device 8. After the bottom end surface of the feeding tank 1 extends into the circular through hole, the raw materials in the feeding tank 1 can enter the cleaning recovery device 8 through the feeding tank 1 through the control of the electromagnetic valve.

[0025] Combination Figure 2 A cavity is provided in the cleaning recovery device 8, and rectangular grooves are respectively provided in the middle of the inner walls on both sides of the cavity, and the two rectangular grooves are symmetrically distributed. An upper filter screen 9 is placed in the rectangular groove, and a vibration motor 10 is installed at the bottom end of the upper filter screen 9. A protrusion of at most 2 cm is provided on the inner wall of the long side of the cleaning recovery device 8, and the bottom end surface of the vibration motor 10 is provided on the protrusion.

[0026] Feeding slopes 11 are symmetrically arranged below the upper filter screen 9. The feeding slopes 11 are symmetrically distributed, and the inclination direction of each feeding slope 11 is downwardly inclined from the inner wall position of the cleaning recovery device to the middle position of the inner cavity of the cleaning recovery device.

[0027] A base plate 12 is arranged below the feeding ramp 11. There are two base plates 12 and they are symmetrically distributed. The interior of the base plate 12 is hollow. An electric telescopic rod is installed in the base plate 12. The electric telescopic rod is drivably connected to the output end of the PLC. The front end of one electric telescopic rod is connected to a telescopic groove plate 13, and the front end of the other electric telescopic rod is connected to a telescopic protrusion plate 14. The telescopic groove plate 13 or the telescopic protrusion plate 14 can move forward or backward under the drive of the electric telescopic rod to which they are connected. When they move backward, the outer wall of the telescopic groove plate 13 or the outer wall of the telescopic protrusion plate 14 respectively contacts the inner wall of the base plate 12 at their position.

[0028] A touch sensor is installed inside the telescopic groove plate 13, and the touch sensor can be connected to the input end of the PLC in a feedback manner. When the telescopic groove plate 13 and the telescopic protrusion plate 14 are pushed forward by their respective electric telescopic rods until the groove at the front end of the telescopic groove plate 13 and the protrusion at the front end of the telescopic push plate 14 contact, the surface of the telescopic protrusion 14 contacts the touch sensor in the telescopic groove plate 13, and the touch sensor sends an electrical signal to the PLC. After receiving the electrical signal, the PLC controls the electric telescopic rod to stop working.

[0029] In order to ensure that the device is sealed and connected to the inner wall of the cleaning recovery device 8 when the telescopic groove plate 13 and the telescopic protrusion plate 14 are in contact, a sealing strip for sealing connection is adhered to the inner wall of the cleaning recovery device 8 corresponding to the travel trajectory of the telescopic groove plate 13 and the telescopic push plate 14.

[0030] A forward roller 18 and a reverse roller 17 are arranged below the telescopic groove plate 13, and a drive installation box is arranged at the rear end of the cleaning recovery device 8. A main motor 81 is arranged in the drive installation box. The front end of the rotating shaft of the main motor 81 is connected to a main gear and then passes through the rear wall of the cleaning recovery device 8, and is connected to the rear end of the forward roller 18 in the cleaning recovery device 8.

[0031] On both sides of the main gear, there are meshing gears 84 connected by rotating shafts. A rectangular groove for fixing the connecting piece is provided on the rear wall of the cleaning recovery device 8 through which the meshing gear 84 passes. The exterior of the connecting piece is a rectangular structure and a circular opening for installing the bearing is provided on the surface of the connecting piece. The bearing is pressed in the circular opening of the connecting piece. A transmission shaft is welded to the inner wall of the meshing gear 84, and the transmission shaft passes through the front end bearing and is connected to the rear end of the meshing gear 84. In this way, when the main gear is driven by the main motor 81 to rotate, the meshing gear 84 and the main gear mesh with each other and start to rotate.

[0032] An air inlet 15 is provided on the rear wall of the drive installation box, and a centrifugal fan 82 is installed above the air inlet 15 and on the rear wall of the cleaning recovery device 8. The air outlet of the centrifugal fan 82 is connected to the variable air duct 83 through a gas solenoid valve. An electric heating belt is coiled inside the variable air duct 83. The maximum heating temperature of the electric heating belt does not exceed the melting temperature of maltodextrin. The normal temperature air sucked in by the centrifugal fan 82 is converted into hot air after passing through the inside of the electric heating tube 83. The hot air enters the cleaning recovery device 8 through the air inlet 15.

[0033] A plurality of air outlets 16 are provided on the side wall of the cleaning recovery device 8 , and the surface of each air outlet 16 is connected to an exhaust pipe via a solenoid valve.

[0034] The electric heating belt is connected to the output end of the PLC through the driving module, and the centrifugal fan 82 is also connected to the output end of the PLC. When the touch sensor in the telescopic groove plate 13 detects that the telescopic groove plate 13 and the telescopic protrusion plate 14 are in contact, the centrifugal fan 82 is driven by the PLC to start working. When the centrifugal fan 82 starts working, the electric heating belt located inside the variable air duct 83 starts working at the same time.

[0035] A discharge port 19 is arranged on the bottom end surface of the cleaning recovery device 8, and a hydraulic rod is arranged on the bottom end surface of the discharge port 19. An outlet baffle is installed at the front end of the hydraulic rod. When the hydraulic rod moves forward and drives the outlet baffle forward, the outlet baffle just covers the discharge port 19 so that the material in the cleaning recovery device 8 will not leak out. A sealing strip is arranged at the position where the lower wall of the cleaning recovery device 8 fits the outlet baffle.

[0036] A material receiving bucket 20 is placed below the discharge port 19 .

[0037] Working principle: the user first connects the device to an external control power supply, the control device is powered on to work, the user opens the sealing cover 2, and pours the raw materials into the feeding tank 1 through the opening at the sealing cover 2. After feeding, the user covers the sealing cover 2. At this time, the user starts working by controlling the device through the Bluetooth switch. The solenoid valve at the outlet of the feeding tank 1 is in an open state, and the raw material solenoid valve enters the cleaning recovery device 8. In the cleaning recovery device 8, it first contacts the upper filter screen 9. The vibration motor 10 at the bottom of the upper filter screen 9 starts to vibrate under the drive of the PLC. While vibrating, maltodextrin falls onto the feeding ramp 11. At the same time, the agglomerated maltodextrin is dispersed by the vibration and falls into the interior of the cleaning recovery device 8 through the feeding ramp 11. When the object sensor at one end of the feeding ramp 11 detects that no object has fallen, the electric telescopic rod in the control substrate 12 is extended and retracted. As the two electric telescopic rods move forward, the telescopic groove plate 13 and the telescopic protrusion plate 14 get closer and closer, and finally snap together.

[0038] The side walls of the telescopic groove plate 13 and the side walls of the telescopic protrusion plate 14 are respectively connected to the sealing strips of the inner wall of the cleaning and recovery device 8, so that the telescopic groove plate 13, the telescopic protrusion plate 14 and the inner wall of the cleaning and recovery device 8 form a sealed connection. At the same time, the hydraulic rod located at the discharge port 19 pushes the outlet baffle plate out and seals it in contact with the lower surface of the cleaning and recovery device 8. At this time, the space between the lower part of the telescopic groove plate 13 and the telescopic protrusion plate 14 and the upper part of the lower wall of the cleaning and recovery device 8 is in a sealed state.

[0039] PLC controls the centrifugal fan 82 to start working. The centrifugal fan 82 sends wind into the air change duct 83 through the air inlet 15. The electric belt in the air change duct 83 starts to heat up, and the passing normal temperature wind is converted into hot air and sent into the cleaning recovery device 8. The centrifugal fan 82 works for 2 minutes each time. The solenoid valve on the surface of the air outlet 16 is opened once every 10 minutes. When the air outlet 16 is opened, the hot air is discharged through the air outlet 16. The opening time of the air outlet 16 is 4 minutes. The centrifugal fan 82 starts to work again for 2 minutes, and the air outlet 16 is closed again.

[0040] The user sets the working time of the device through the timing button on the Bluetooth remote control, and the main motor 81 drives the forward roller 18 to start rotating. The meshing gear 84 meshing with the gear on the surface of the main motor 81 rotates under the drive of the main motor 81 and drives the reverse roller 17 connected to its respective front end to start moving. When the forward roller 18 and the reverse roller 17 rotate, hot air is driven to circulate. The maltodextrin in the device is fully contacted with the hot air under the drive of the forward roller 18 and the reverse roller 17. The hot air cleans the maltodextrin, achieving the effect of deodorization and sterilization.

[0041] After the timing of the device ends, the cleaning is completed, the device stops working, the hydraulic rod retracts, driving the outlet baffle to retract, and the discharge port 19 leaks out, and the cleaned maltodextrin is discharged from the discharge port 19 to the receiving barrel 20.

[0044] Working principle: when the user puts the material into the feeding tank 1, the user controls the stirring motor 3 to start rotating through the external switch, and the rotating column 5 drives the crushing blades 6 to start rotating inward, and the large pieces of maltodextrin contact the crushing blades 6 and are squeezed between the crushing blades and the inner wall of the feeding tube 1 to produce crushes.
