Description

Technical Field

[0001] The present invention belongs to the technical field of brown sugar production, and particularly relates to a brown sugar boiling equipment and a brown sugar boiling process for producing brown sugar. Background Art

[0002] Brown sugar processing is a process of converting sugar-containing raw materials such as sugarcane into brown sugar products through a series of processes. Its basic steps include squeezing sugarcane to obtain sugarcane juice, clarifying to remove impurities, and then boiling. During boiling, the water in the sugar liquid continuously evaporates, and the concentration of sugar gradually increases. During this period, proper stirring is required to make the sugar liquid evenly heated and prevent local overheating and charring; when the sugar liquid reaches a certain concentration, it is cooled and solidified, and then processed through crushing, forming, etc., and finally made into the common brown sugar products on the market.

[0003] However, in the traditional brown sugar boiling process, the production process has a high dependence on manual operation. Taking the discharging link as an example, after the boiling process is completed, the operator has to manually pour the sugar liquid by manpower. Since the brown sugar liquid has a very high viscosity, the flow rate is extremely slow during pouring. The whole process is time-consuming and laborious. The operator needs to maintain a high degree of concentration and a large amount of force for a long time to barely push the sugar liquid out. This operation method not only has extremely low efficiency but also seriously slows down the production progress. Summary of the Invention

Detailed implementation manners

[0018] Referring to "embodiments" herein means that the specific features, structures or characteristics described in connection with the embodiments may be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0019] An embodiment of the present invention provides a sugar boiling device and a sugar boiling process for producing brown sugar, as Figures 1-10As shown in the figure, a sugar-boiling device for producing brown sugar includes: a base plate 1, on which a base box 2 is provided; a sugar-boiling tank 3, which is arranged on the base box 2, and a tank cover 4 is provided on the sugar-boiling tank 3, and an inner tank 5 is arranged therein; a heating device, including an electromagnetic induction heating coil 6 and a far-infrared heating plate 7, the electromagnetic induction heating coil 6 and the far-infrared heating plate 7 are arranged on the sugar-boiling tank 3 and are in contact with the inner tank 5; a pushing mechanism, which is arranged in the inner tank 5 and can move to push the sugar liquid out when the sugar-boiling tank 3 is tilted; a stirring mechanism arranged in the inner tank 5 for stirring the brown sugar material; a tilting mechanism arranged on the base box 2, which is used to control the tilting of the sugar-boiling tank 3; a linkage air supply mechanism arranged on the base plate 1, which is used to supply gas into the air chamber between the pushing plate 8 and the inner tank 5.

[0020] In this embodiment, when the device is started, first, the inner tank 5 in the sugar-boiling tank 3 is heated doubly by the electromagnetic induction heating coil 6 and the far-infrared heating plate 7, and the stirring mechanism is started synchronously to fully mix and boil the brown sugar raw materials. Before the sugar liquid reaches the process requirements, the tank cover 4 remains closed to ensure the tightness and hygiene of the boiling process; when discharging materials, the tilting mechanism drives the sugar-boiling tank 3 to tilt to a preset angle, and at the same time, the linkage air supply mechanism injects high-pressure gas into the air chamber between the pushing plate 8 and the inner tank 5. The pushing plate 8 slides along the inner wall of the inner tank 5 under the action of air pressure, and quickly pushes the high-viscosity sugar liquid to the discharge port; through the coordinated operation of the tilting mechanism and the pushing mechanism, compared with the traditional time-consuming and laborious manual discharging, the discharging efficiency is increased by more than 60%. The double heating device makes the sugar liquid heated evenly, and the air-pushing discharging technology reduces the sugar liquid residue, and the overall energy consumption of the device is reduced by 35%, significantly improving the production environment and operation safety.

[0021] In a further preferred embodiment of the present invention, the adjusting mechanism includes: a pushing plate 8 arranged in the inner tank 5; a spline sleeve 11 rotatably installed on the inner tank 5 through a bearing, and the bottom end of the spline sleeve 11 drives the sugar-boiling tank 3; a spline tube 12 rotatably installed on the pushing plate 8 through a sealed bearing, and the bottom end of the spline tube 12 passes through the spline sleeve 11 and extends outside the sugar-boiling tank 3.

[0022] In this embodiment, when discharging materials, torque is transmitted through the spline tube 12, and the key tooth structure of the spline tube 12 and the spline sleeve 11 realizes axial sliding and circumferential transmission. When the sugar-boiling tank 3 is tilted to a 45-degree discharging angle, the pushing plate 8 slides along the inner wall of the inner tank 5 under the push of air pressure, and at the same time, the spline tube 12 moves synchronously with the pushing plate 8, and its outer spline always remains engaged with the inner spline of the spline sleeve 11; so that the pushing plate 8 can still maintain a straight movement track in the complex movement of the tilted tank body. The axially telescopic spline structure allows the pushing plate 8 to adjust the stroke within a set range.

[0023] In a further preferred embodiment of the present invention, the stirring mechanism includes: a turbine stirrer 13 fixed on the spline tube 12 for stirring the sugar solution; a bracket 9 symmetrically fixed on the spline tube 12 through a connecting block; and a scraper 10 fixed on the corresponding bracket 9 for hanging materials.

[0024] In this embodiment, during the sugar boiling process, the spline tube 12 rotates at a speed of 120 - 180 r / min driven by a driving device, and the turbine stirrer 13 fixed thereon forms a three-dimensional spiral stirring flow field. The scraper 10 and the bracket 9 form a scraping component with an adjustable angle through a connecting block, and its cutting edge always maintains a 0.5 mm gap with the inner wall of the inner tank 5, continuously scraping the attached sugar solution during rotation to prevent sticking to the pan and coking; through the combined movement of the turbine and the scraper, the mixing uniformity of the sugar solution is increased to 99.6%, and the stirring efficiency is 2.3 times higher than that of the traditional paddle type.

[0025] In a further preferred embodiment of the present invention, the pouring mechanism includes: a first rotating rod 14 symmetrically assembled on the base box 2 through a bearing seat; a connecting frame 15 fixed on the first rotating rod 14, and the connecting frame 15 is fixedly connected to the outer wall of the sugar boiling tank 3; a fifth bevel gear 40 fixed on the corresponding first rotating rod 14 for transmission.

[0026] In this embodiment, when it is necessary to pour the sugar solution, the first rotating rod 14 is driven to rotate through the fifth bevel gear 40, and the connecting frame 15 rotates synchronously with the rotating rod 14, so that the sugar boiling tank 3 tilts smoothly around the axis of the first rotating rod 14. The pouring angle can be accurately adjusted within the range of 0 - 90° through a control system. When the sugar solution in the tank reaches the discharging position, the pushing plate 8 moves to form a cooperative discharging mode of mechanical pushing and gravity drainage; through the bevel gear transmission, the maximum tilting angular velocity of the sugar boiling tank 3 is increased, and the pouring efficiency is improved compared with the traditional manual pouring.

[0027] In a further preferred embodiment of the present invention, the linkage air supply mechanism includes: an air tank 20 fixedly installed on the base plate 1, and a first screw rod 21 is rotatably installed in the air tank 20 through a bearing; a piston plate 22 threadedly sleeved on the first screw rod 21; pulley wheels 23 respectively fixedly installed on the first screw rod 21 and the first rotating rod 14, and a transmission belt 24 is sleeved on the corresponding pulley wheels 23; a first telescopic tube 25 fixedly communicated with the air tank 20, and the air outlet end of the first telescopic tube 25 is communicated with the spline tube 12 through a rotary joint 26.

[0028] In this embodiment, when the dumping mechanism drives the first rotating rod 14 to rotate, its pulley 23 drives the first screw rod 21 in the air box 20 to rotate synchronously through the transmission belt 24. The piston plate 22 with a threaded sleeve on the first screw rod 21 is under the guiding and limiting action and moves along the axis direction of the screw rod to compress the air in the air box 20. The high-pressure air flow passes through the first telescopic tube 25 and the rotary joint 26, and is injected into the air chamber between the pushing plate 8 and the inner tank 5 through the hollow channel of the spline tube 12, pushing the pushing plate 8 to advance forward at a speed of 0.3 m / s; the design of the rotary joint 26 allows the spline tube 12 to rotate while maintaining the airtightness of the air path. This linkage air supply mechanism realizes the complete synchronization of the dumping action and the air supply operation through mechanical transmission, and is relatively energy-saving compared with the traditional independent air supply system.

[0029] In a further preferred embodiment of the present invention, a near-infrared spectrum sensor 48 is provided on the inner wall of the tank cover 4, and a pressure gauge for detecting air pressure is assembled on the tank cover 4.

[0030] In this embodiment, during the sugar boiling process, the near-infrared spectrum sensor 48 collects the spectrum data of the sugar solution in real time, penetrates the sugar solution, and analyzes key parameters such as the sugar solution concentration and moisture content through algorithms. The pressure gauge synchronously monitors the change of the air pressure in the tank. When the sugar solution concentration reaches 92% ± 0.5%, the control system is triggered to automatically reduce the heating power by 15% and increase the stirring speed to 200 r / min to ensure uniform supersaturation; this monitoring system realizes the non-contact on-line detection of the sugar solution quality through the near-infrared spectrum sensor 48, and the concentration detection accuracy reaches ±0.3%, which improves the efficiency by 5 times compared with manual sampling inspection. The dynamic monitoring of the pressure gauge improves the operation safety of the equipment, and with the intelligent control strategy, the product qualification rate is improved.

[0031] In a further preferred embodiment of the present invention, a second telescopic tube 47 for exhausting gas is fixedly communicated with the tank cover 4, and a gas valve is provided on the second telescopic tube 47. A temperature controller adapted to the electromagnetic induction heating coil 6 and the far-infrared heating plate 7 is provided on the outer wall of the sugar boiling tank 3.

[0032] In this embodiment, at the initial stage of sugar boiling, the thermostat monitors the temperatures of the electromagnetic induction heating coil 6 and the far-infrared heating plate 7 in real time, and dynamically adjusts the heating power through the PID algorithm, so that the temperature of the inner tank 5 rises to 120 °C within 15 minutes and is stably maintained. At the same time, the air valve on the second telescopic pipe 47 opens at a 15% opening degree to discharge the initial water vapor. When the near-infrared spectrum sensor 48 detects that the sugar solution concentration exceeds 70%, the air valve automatically closes to a 5% micro-discharge state to maintain a slightly positive pressure environment in the tank. Three minutes before discharging, the thermostat reduces the heating power to 30%, and cooperates with the pneumatic pushing action of the pushing plate 8 to reduce the sugar solution temperature gradient to 5 °C / cm. When it is detected that the temperature of the sugar solution at the discharge port is lower than 105 °C, the thermostat automatically triggers the electromagnetic induction heating coil 6 for local compensation heating to ensure the fluidity of the sugar solution. The second telescopic pipe 47 maintains a 10% opening degree throughout the discharging process, and synchronously discharges the trace steam generated during the pushing process. This temperature control and exhaust system realizes precise temperature control through intelligent linkage. Compared with traditional manual temperature adjustment, the temperature deviation is reduced from ±8 °C to ±2 °C, and the caramelization rate of the product is reduced by 62%. The dynamic air valve control of the second telescopic pipe 47 reduces the steam emission by 40%. Combined with the stepped temperature reduction strategy of the thermostat, the overall energy consumption is reduced by 29%. The modular thermostat supports resetting the parameters of the heating device within 5 minutes, and the flexibility of the equipment to adapt to the production of different sugar products is increased by 3 times.

[0033] In a further preferred embodiment of the present invention, an air passage 49 and air holes 50 are provided on the spline tube 12 for supplying gas into the air chamber between the pushing plate 8 and the inner tank 5.

[0034] In this embodiment, during discharging, high-pressure air flows into the annular air chamber on the back of the pushing plate 8 through the air passage 49 of the spline tube 12, and is vertically sprayed onto the inner wall of the inner tank 5 through the uniformly distributed air holes 50 at a pressure of 0.8 MPa. The pushing plate 8 advances at a speed of 0.4 m / s under the drive of air pressure, and cooperates with the sugar boiling tank 3 with an inclination angle of 60° to form a combined discharging power of air pushing and gravity.

[0035] In a further preferred embodiment of the present invention, an adjustable adjusting frame 19 is fixedly installed on the tank cover 4 for controlling the opening and closing of the tank cover 4, and a second bevel gear 31 for transmission is fixedly installed on the spline tube 12.

[0036] In this embodiment, by rotating the adjusting frame 19, the tank cover 4 can be smoothly opened or closed. The spline tube 12 can receive external power through the second bevel gear 31 to realize independent transmission control of the stirring mechanism and the pushing mechanism.

[0037] In order to further improve the use effect of this device, in addition to the above solutions, this solution also has the following embodiments: In another embodiment of the present invention, a power mechanism for providing power is disposed inside the base box 2. The power mechanism includes: a motor 27 and a speed regulator 28 disposed inside the base box 2, an output shaft of the motor 27 being fixedly connected to an input shaft of the speed regulator 28 through a coupling; a first transmission rod 29 assembled inside the base box 2 through a bearing seat, the first transmission rod 29 being fixedly connected to an output shaft of the speed regulator 28 through a coupling; a first bevel gear 30 fixed on the first transmission rod 29, the first bevel gear 30 being engagable with a second bevel gear 31.

[0038] In this embodiment, when the power mechanism is started, the motor 27 drives the speed regulator 28 through a coupling, and power is transmitted to the first bevel gear 30 through the first transmission rod 29; when the second bevel gear 31 meshes with the first bevel gear 30, the spline tube 12 rotates at a speed, synchronously driving the turbine stirrer 13 and the scraper 10 to perform a stirring operation.

[0039] In another embodiment of the present invention, a linkage mechanism for controlling the adjustment frame 19 and the tank cover 4 is disposed on the base box 2. The linkage mechanism includes: an assembly box 16 fixedly installed on the base box 2, a mounting seat 17 being fixedly installed on the assembly box 16, a rotating shaft 18 being rotatably equipped on the mounting seat 17 through a bearing, the rotating shaft 18 being fixedly connected to the adjustment frame 19; a gear 46 fixed on the rotating shaft 18; a second screw rod 42 assembled inside the assembly box 16 through a bearing, a toothed groove plate 41 meshing with the gear 46 being sleeved on the second screw rod 42 through a thread; a guide rod 44 fixed inside the assembly box 16, a sleeve block 45 being slidably sleeved on the guide rod 44, the sleeve block 45 being fixedly connected to the toothed groove plate 41; a sixth bevel gear 43 respectively fixed and installed on the second screw rod 42 and the first rotating rod 14 and meshing with each other; a second transmission rod 32 assembled on the base box 2 through a bearing, a third bevel gear 33 meshing with each other being fixedly installed on a bottom end of the second transmission rod 32 and an output shaft of the motor 27; a second spline shaft 34 fixed on a top end of the second transmission rod 32; an electric telescopic rod 35 fixedly installed inside the assembly box 16, an assembly plate 36 being fixed on an output rod of the electric telescopic rod 35, a spline cylinder 38 being assembled on the assembly plate 36 through a bearing, the spline cylinder 38 being sleeved on the second spline shaft 34 for transmission; a fourth bevel gear 39 fixed on the spline cylinder 38, the fourth bevel gear 39 being engagable and separable from a fifth bevel gear 40.

[0040] In this embodiment, when it is necessary to pour the sugar solution, the electric telescopic rod 35 is controlled to start and extend, the assembly plate 36 descends to make the spline cylinder 38 and the third spline shaft 37 sleeved on the second spline shaft 34, and the fourth bevel gear 39 meshes with the fifth bevel gear 40 synchronously. The power of the motor 27 is transmitted to the second transmission rod 32 through the third bevel gear 33, drives the fourth bevel gear 39 to rotate through the spline cylinder 38, drives the fifth bevel gear 40 to rotate the first rotating rod 14, and tilts the sugar boiling tank 3 to the discharging angle. At the same time, the sixth bevel gear 43 transmits the rotation of the first rotating rod 14 to the second screw rod 42, the toothed groove plate 41 moves along the guide rod 44, and drives the rotating shaft 18 through the gear 46 to open the tank cover 4 prior to the sugar tank 3; After the discharging is completed, the electric telescopic rod 35 contracts to make the spline cylinder 38 sleeved on the third spline shaft 37 again, and the fourth bevel gear 39 is separated from the fifth bevel gear 40. At this time, the power of the second transmission rod 32 drives the second screw rod 42 to reverse through the second spline shaft 34, the toothed groove plate 41 drives the gear 46 to rotate the rotating shaft 18, and the adjusting frame 19 and the tank cover 4 are reset. The sixth bevel gear 43 synchronously converts the rotation of the second screw rod 42 into the linear motion of the guide rod 44 to ensure the precise synchronization of the tank cover opening and the tank body resetting actions; through the power switching design of the electric telescopic rod 35, this linkage mechanism realizes the full-automatic coordinated control of the opening and closing of the tank cover 4 and the tilting action.

[0042] In this embodiment, after the tank cover 4 is closed, the electric telescopic rod 35 starts to extend the output rod, and the spline cylinder 38 descends to a specific height. At this time, the bottom end of the third spline shaft 37 still remains in a sleeved state with the spline cylinder 38. When the second spline shaft 34 rotates with the motor 27, the third spline shaft 37 is driven by the spline cylinder 38 to rotate at a high speed of 1500 r / min, and the fan blade 53 at its top rotates synchronously to generate centrifugal force, exhausting the air in the gas guiding shell 51 through the first air outlet pipe 55, reducing the oxygen in the sugar boiling tank 3 to form a vacuum environment; which is beneficial to subsequent boiling.

[0046] In summary, compared with the related technologies, efficient brown sugar boiling and discharging are achieved through the cooperation of multiple mechanisms. The electromagnetic induction heating coil 6 and the far-infrared heating plate 7 are heated doubly. Combining the turbine stirrer 13 and the scraper 10 of the stirring mechanism, the sugar solution is heated evenly. The near-infrared spectrum sensor 48 and the pressure gauge monitor in real time, and the temperature controller and the second telescopic tube 47 precisely control the temperature and pressure to reduce the caramelization rate; the tilting mechanism drives the sugar boiling tank 3 to tilt, and the linkage air supply mechanism pushes the pushing plate 8 through the air duct 49 and the air hole 50 of the spline tube 12, and combines with gravity to quickly discharge the material, improving the efficiency. The linkage mechanism controls the opening and closing of the tank cover 4 to be synchronized with the tilting of the tank body. The air guiding mechanism evacuates the air to reduce the oxidation rate, and the condensing mechanism recovers the steam, improving the overall production environment.
