Description

Technical Field

[0001] This invention belongs to the field of baking powder moisture evaporation technology, specifically relating to a biological enzyme modified baking powder moisture evaporation device. Background Technology

[0002] Enzyme-modified starch is produced by treating natural starch with specific enzymes. These enzymes break down starch molecules into smaller fragments, thereby improving viscosity, solubility, and other functional properties. Enzyme-modified starch is commonly used in the production of baked goods. Using bio-enzyme-modified baking starch during baking can greatly enhance the taste of food. However, during storage, enzyme-modified starch is easily penetrated by moisture in the air and clumps together. It is necessary to use a moisture evaporation device to evaporate the moisture from the enzyme-modified starch to ensure its quality. Existing moisture evaporation devices can only simply recover and utilize the waste heat of the steam during the evaporation process of enzyme-modified starch, but cannot recover and utilize the heat generated in the steam during the evaporation process, resulting in a great waste of energy and poor evaporation effect of enzyme-modified starch. Summary of the Invention

[0003] The purpose of this invention is to provide a device for drying moisture from bio-enzyme-modified baking powder, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A device for drying moisture from bio-enzyme-modified baking powder includes a modified starch drying tank, a steam heating chamber, and a steam generator. The steam generator is connected to the steam heating chamber via a gas supply pipe, and the steam heating chamber has a protrusion on one side. Steam generated by the steam generator is supplied into the steam heating chamber to heat and dry the enzyme-modified starch inside the modified starch drying tank. A stirring module is fixedly installed in the middle of the modified starch drying tank. While the enzyme-modified starch is being heated and dried by steam, a rotary motor assembly on the stirring module is activated. The rotary motor assembly can be opened through a hollow core... A rotating rod drives the stirring assembly to rotate, which in turn tumbles and stirs the enzyme-modified starch, ensuring even heating and good drying. A guide conveyor module is fixedly installed on one side of the stirring module at the top of the modified starch drying tank, and a first transmission assembly connects the guide conveyor module to the stirring module. While stirring and tumbling, the stirring module can drive the drive rod on the guide conveyor module to rotate via the first transmission assembly. The drive rod, in turn, drives the fan impeller assembly to rotate. The rotation of the fan impeller assembly agitates the enzyme-modified starch inside the modified starch drying tank. The hot air generated during the powder drying process is fed into a steam dryer, which quickly dries the moisture in the hot air. A modified starch filter module is fixedly connected to the bottom of the guide and conveying module. This modified starch filter module intercepts and filters the modified starch mixed in with the hot air, preventing it from escaping from the guide and conveying module. The bottom of the stirring module is rotatably connected to a first air inlet pipe via a bearing. One end of the first air inlet pipe is fixedly connected to a heat exchange module, which is connected to a steam heating chamber via a gas supply pipe. The dried hot air is then passed through... The gas flows into the heat exchange module through the pipe fitting. The heat exchange module can exchange heat between the hot gas generated during the evaporation of enzyme-modified starch and the steam generated during the evaporation. The steam can reheat the hot gas generated during the evaporation of enzyme-modified starch. The heated hot gas is finally blown out from the hot gas outlet on the stirring module. This can quickly and evenly dry the enzyme-modified starch in the modified starch evaporation tank. The top of the heat exchange module is connected to a second air inlet pipe fitting, and the top of the heat exchange module is connected to the flow guiding and conveying module through the second air inlet pipe fitting. A water vapor dryer is connected to the second air inlet pipe fitting.

[0006] A vibration module is installed between the outside of the stirring module and the flow guiding and conveying module. A cleaning component is connected to the bottom of the flow guiding and conveying module, which passes through the modified starch filtration module. An agglomeration crushing device is fixedly installed on the top side of one side of the modified starch drying tank, and a second transmission component connects the agglomeration crushing device to the stirring module. While the stirring module tumbles and stirs the enzyme-modified starch, it can drive the rotating shaft on the agglomeration crushing device to rotate via the second transmission component. The rotation of the rotating shaft drives the crushing blade assembly and the spiral feeder to rotate. The rotation of the crushing blade assembly can crush the added enzyme-modified baking powder, preventing the damp enzyme-modified baking powder from clumping together and affecting the drying process. The rotation of the spiral feeder not only allows for precise control... The feeding speed of the bio-enzyme modified baking powder is improved, and the blockage of the discharge port can be effectively avoided, which would affect the normal feeding of the bio-enzyme modified baking powder. The guide and conveying module can drive the cleaning component to rotate while conveying hot air. The cleaning component can clean the bottom of the modified starch filter module, which can prevent the filter holes at the bottom of the modified starch filter module from being blocked by enzyme-modified starch, thus affecting normal filtration and hot air discharge. At the same time, the vibration module can drive the guide and conveying module to vibrate under the linkage of the stirring module, which can further prevent the filter holes at the bottom of the modified starch filter module from being blocked by enzyme-modified starch. This can effectively increase the hot air discharge efficiency and improve the secondary hot air drying efficiency of the enzyme-modified starch by the recovered hot air.

[0007] Preferably, the stirring module includes a mounting frame and a rotary motor assembly fixedly welded to the top of the modified starch drying tank. A hollow rotating rod is fixedly connected to the end of the output shaft of the rotary motor assembly, and a stirring component is fixedly mounted on the outside of the hollow rotating rod. When the rotary motor assembly on the stirring module is turned on, the rotary motor assembly can drive the stirring component to rotate through the hollow rotating rod. When the stirring component rotates, it can tumble and stir the enzyme-modified starch, so that the enzyme-modified starch is heated evenly.

[0008] Hot air outlets are fixed at equal intervals on the outer side of the hollow rotating rod, and a first filter membrane is provided in the inner cavity of the end of the hot air outlet. The enzyme-modified starch can be intercepted and filtered through the first filter membrane, which can prevent the enzyme-modified starch from entering the hot air outlet.

[0009] Preferably, the stirring assembly includes a mixing component, with crushing blades fixedly arranged at equal intervals inside the mixing component. The side of the mixing component that contacts the modified starch drying tank has a groove that matches the protrusion on the inner wall of the modified starch drying tank. The protrusion increases the heating area during the drying of the enzyme-modified starch, thereby improving the drying efficiency. By providing the groove, which fits the protrusion, the stirring assembly can scrape and clean the inner wall of the modified starch drying tank while stirring the enzyme-modified starch, thus preventing the enzyme-modified starch from adhering to the inner wall of the modified starch drying tank.

[0010] Preferably, the flow guiding and conveying module includes a cylindrical shell and a driving rod. The driving rod and the cylindrical shell are rotatably connected by a bearing, and the cleaning component is fixedly connected to the bottom end of the driving rod. Fan impeller assemblies are fixedly provided at equal intervals on the outside of the driving rod. While stirring and tumbling, the stirring module can drive the driving rod on the flow guiding and conveying module to rotate through the first transmission component. The driving rod can drive the fan impeller assembly to rotate. When the fan impeller assembly rotates, it can transport the hot air generated during the evaporation of enzyme-modified starch inside the modified starch evaporation tank into the water vapor dryer. The water vapor dryer can quickly dry the water vapor in the hot air.

[0011] Preferably, the modified starch filtration module includes a gas collection hood, a support plate is fixedly provided in the inner cavity at the bottom of the gas collection hood, and the support plate is made of stainless steel mesh. A second filter membrane is fixedly provided at the bottom of the support plate. The modified starch mixed in the hot gas can be intercepted and filtered through the second filter membrane, which can prevent the modified starch from being discharged from the guide and conveying module.

[0012] Both the second and first filter membranes are made of polytetrafluoroethylene (PTFE). PTFE air filter membranes are made of polytetrafluoroethylene and are expanded and stretched to form a microporous membrane. They have excellent waterproof, moisture-permeable, breathable, corrosion-resistant, aging-resistant, and high-temperature-resistant properties. Accumulated dust can be easily removed by mechanical vibration or wiping, making cleaning convenient and providing good interception and filtration effects.

[0013] Preferably, the vibration module includes a vibrating disc fitted outside the stirring module and an annular plate fitted outside the flow guiding and conveying module. The vibrating disc has equidistant mounting slots on its outer side, and a hammering vibrator is inserted into the inner cavity of the mounting slot. The vibrating disc on the vibration module rotates rapidly under the drive of the stirring module. While the vibrating disc rotates rapidly, the hammering vibrator on its outer side can hammer the annular plate, thereby driving the flow guiding and conveying module to vibrate. This can further prevent the filter holes at the bottom of the modified starch filtration module from being blocked by the enzyme-modified starch, effectively increase the efficiency of hot air discharge, and effectively improve the efficiency of secondary hot air drying of the enzyme-modified starch by the recovered hot air.

[0014] The hammer vibration component includes a spring assembly, which is fixedly installed at one end inside the mounting slot. The other end of the spring assembly is fixedly connected to an impact component, one end of which passes through the inner cavity of the mounting slot, and the end of the impact component is designed as a smooth arc-shaped structure.

[0015] Preferably, the heat exchange module includes a cylindrical outer shell, with an upper gas collecting box and a lower gas collecting box fixedly connected to its upper and lower ends, respectively. A heat exchange pipe is connected between the upper and lower gas collecting boxes, and heat exchange fins are fixedly provided at equal intervals on the inner wall of the heat exchange pipe. A steam delivery pipe is connected to one side of the top of the cylindrical outer shell. The hot gas generated during the evaporation of enzyme-modified starch flows into the heat exchange pipe through the upper gas collecting box at the top of the heat exchange module. The heat exchange pipe allows for heat exchange between the hot gas generated during the evaporation of enzyme-modified starch and the steam generated during evaporation. The steam can reheat the hot gas generated during the evaporation of enzyme-modified starch. The heated hot gas is finally blown out from the hot gas outlet on the stirring module, which can quickly and evenly dry the enzyme-modified starch in the modified starch evaporation tank.

[0016] Preferably, the agglomeration crushing device includes a starch storage bin. A rotating shaft is rotatably connected to the center of the starch storage bin via a bearing. The top of the rotating shaft is connected to the stirring module via a second transmission assembly. Crushing blade assemblies are fixedly arranged at equal intervals on the outer side of the rotating shaft. A spiral feeding paddle is fixedly arranged below the crushing blade assemblies on the outer side of the bottom end of the rotating shaft. A feeding port and a discharging port are respectively provided at the top and bottom of one side of the starch storage bin, and the spiral feeding paddle passes through the inside of the discharging port. While the stirring module is turning and stirring the enzyme-modified starch, it can drive the rotating shaft on the agglomeration crushing device to rotate through the second transmission assembly. When the rotating shaft rotates, it can drive the crushing blade assembly and the spiral feeding paddle to rotate. The rotation of the crushing blade assembly can crush the added enzyme-modified baking powder, which can prevent the moisture-affected enzyme-modified baking powder from agglomerating and affecting the drying process. When the spiral feeding paddle rotates, it can not only accurately control the feeding speed of the enzyme-modified baking powder, but also effectively prevent the outlet from being blocked, thus avoiding the normal feeding of the enzyme-modified baking powder.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In use, this invention involves evaporating enzyme-modified starch in a modified starch evaporation tank using steam. The stirring module is activated to agitate the enzyme-modified starch, ensuring even heating. Simultaneously, the stirring module drives a flow guiding module via a first transmission component. This flow guiding module, in conjunction with the other components, directs the hot air generated during the evaporation of the enzyme-modified starch into a water-steam dryer for further drying. The dried hot air then flows through pipes into a heat exchange module, where heat is exchanged between the hot air and the steam generated during evaporation. The steam further reheats the hot air, and the heated air is finally blown out from the hot air outlet on the stirring module, thus achieving a second, rapid air-drying process for the enzyme-modified starch in the evaporation tank.

[0019] The flow guiding and conveying module transports hot air while simultaneously driving the cleaning component to rotate. The cleaning component cleans the bottom of the modified starch filtration module, preventing the filter holes at the bottom of the modified starch filtration module from being clogged by the enzyme-modified starch, thus affecting normal filtration and the discharge of hot air. At the same time, the vibration module, in conjunction with the stirring module, drives the flow guiding and conveying module to vibrate, further preventing the filter holes at the bottom of the modified starch filtration module from being clogged by the enzyme-modified starch. This effectively increases the discharge efficiency of hot air and improves the efficiency of the secondary hot air drying of the enzyme-modified starch by the recovered hot air.

The heat exchange module 9 can exchange heat between the hot air generated during the evaporation of enzyme-modified starch and the steam generated during the evaporation. The steam can reheat the hot air generated during the evaporation of enzyme-modified starch. The heated hot air is finally blown out from the hot air outlet 405 on the stirring module 4. The enzyme-modified starch in the modified starch evaporation tank 1 can be dried quickly and evenly. A water vapor dryer 11 is connected to the second air inlet pipe 10.

[0034] A vibration module 12 is provided between the outside of the stirring module 4 and the flow guiding and conveying module 5. The bottom end of the flow guiding and conveying module 5 passes through the modified starch filter module 7 and is connected to a cleaning component 13. A clumping and crushing device 14 is fixedly provided on the top side of the modified starch drying tank 1, and a second transmission component 15 is connected between the clumping and crushing device 14 and the stirring module 4. While the stirring module 4 is turning and stirring the enzyme-modified starch, it can drive the rotating shaft 1402 on the clumping and crushing device 14 to rotate through the second transmission component 15. When the rotating shaft 1402 rotates, it can drive the crushing blade assembly 1403 and the spiral feeder 1404 to rotate. The rotation of the crushing blade assembly 1403 can crush the added bio-enzyme modified baking powder, which can prevent the moisture-affected bio-enzyme modified baking powder from clumping together and affecting the drying process. The spiral feeder 1404... When 404 rotates, it can not only precisely control the feeding speed of the enzyme-modified baking powder, but also effectively prevent the discharge port 1406 from being blocked, thus affecting the normal feeding of the enzyme-modified baking powder. While the guiding and conveying module 5 conveys the hot air, it can also drive the cleaning component 13 to rotate.

Crushing blades 408 are fixedly arranged at equal intervals within the inner cavity of the stirring and mixing component 407. Driven by the rotation of the stirring assembly 404, the crushing blades 408 can perform secondary crushing of the lumps of enzyme-modified starch, further improving the evaporation efficiency of the enzyme-modified starch. The side of the stirring and mixing component 407 that contacts the modified starch evaporation tank 1 has a groove 409 that matches the protrusion on the inner wall of the modified starch evaporation tank 1. The protrusion increases the heat-receiving area during the evaporation of the enzyme-modified starch, thus improving the evaporation efficiency. By providing the groove 409, which fits snugly against the protrusion, the stirring assembly 404 can scrape and clean the inner wall of the modified starch evaporation tank 1 while stirring the enzyme-modified starch, preventing the enzyme-modified starch from adhering to the inner wall of the modified starch evaporation tank 1.

[0038] refer to Figure 2 As shown, the flow guiding and conveying module 5 includes a cylindrical shell 501 and a driving rod 502.

The vibrating disc 1201 on the vibration module 12 rotates rapidly under the drive of the stirring module 4. While the vibrating disc 1201 rotates rapidly, the hammering vibrator 1204 on its outer side can hammer the annular plate 1202, which can drive the flow guiding and conveying module 5 to vibrate. This can further prevent the filter holes at the bottom of the modified starch filtration module 7 from being blocked by the enzyme-modified starch, effectively increase the efficiency of hot air discharge, and effectively improve the efficiency of secondary hot air drying of the enzyme-modified starch by the recovered hot air.

[0042] The hammering vibration component 1204 includes a spring assembly, which is fixedly disposed at one end inside the mounting slot 1203. The other end of the spring assembly is fixedly connected to an impact component, one end of which passes through the inner cavity of the mounting slot 1203 and has a smooth arc-shaped structure. During the hammering of the annular plate 1202, when the hammering vibration component 1204 contacts the annular plate 1202, it will compress the spring assembly on it. At this time, the hammering vibration component 1204 retracts into the mounting slot 1203. When the hammering vibration component 1204 moves away from the annular plate 1202, the impact component on the hammering vibration component 1204 will pop out from the mounting slot 1203 under the elastic force of the spring assembly. This structure allows for rapid hammering vibration of the flow guiding and conveying module 5.

The heat exchange tube 904 can exchange heat between the hot air generated during the evaporation of enzyme-modified starch and the steam generated during the evaporation. The steam can reheat the hot air generated during the evaporation of enzyme-modified starch. The heated hot air is finally blown out from the hot air outlet 405 on the stirring module 4, which can quickly and evenly dry the enzyme-modified starch in the modified starch evaporation tank 1.

[0044] refer to Figure 3As shown, the agglomeration crushing device 14 includes a starch storage bin 1401.

A feeding port 1405 and a discharge port 1406 are respectively provided at the top and bottom of one side of the starch storage bin 1401, and the spiral feeder 1404 passes through the discharge port 1406. The stirring module 4... While the enzyme-modified starch is being turned and stirred, the rotating shaft 1402 on the agglomeration crushing device 14 can be rotated through the second transmission component 15. When the rotating shaft 1402 rotates, it can drive the crushing blade assembly 1403 and the spiral feeder 1404 to rotate. The rotation of the crushing blade assembly 1403 can crush the added enzyme-modified baking powder, which can prevent the damp enzyme-modified baking powder from clumping together and affecting the drying process. When the spiral feeder 1404 rotates, it can not only accurately control the feeding speed of the enzyme-modified baking powder, but also effectively prevent the outlet 1406 from being blocked, thus affecting the normal feeding of the enzyme-modified baking powder.

[0045] Working principle: Steam generated by steam generator 3 is fed into steam heating chamber 2 to heat and dry the enzyme-modified starch in the inner cavity of modified starch drying tank 1. Simultaneously with the steam heating and drying of the enzyme-modified starch, the rotary motor assembly 402 on the stirring module 4 is activated. The rotary motor assembly 402 drives the stirring assembly 404 to rotate via the hollow rotating rod 403. The rotation of the stirring assembly 404 tumbles and stirs the enzyme-modified starch, ensuring even heating. While stirring and tumbling, the stirring module 4 drives the drive rod 502 on the guide conveying module 5 to rotate via the first transmission assembly 6. The drive rod 502 then drives the fan impeller assembly 5. When the fan impeller assembly 503 rotates, it can transport the hot air generated during the evaporation of enzyme-modified starch inside the modified starch evaporation tank 1 into the water vapor dryer 11. The water vapor dryer 11 can quickly dry the water vapor in the hot air. The dried hot air flows into the heat exchange module 9 through the pipe. The heat exchange module 9 can exchange heat between the hot air generated during the evaporation of enzyme-modified starch and the steam generated during evaporation. The steam can reheat the hot air generated during the evaporation of enzyme-modified starch. The heated hot air is finally blown out from the hot air outlet 405 on the stirring module 4, which can quickly and evenly dry the enzyme-modified starch in the modified starch evaporation tank 1.

[0046] While the stirring module 4 is tumbling and stirring the enzyme-modified starch, it can drive the rotating shaft 1402 on the agglomeration crushing device 14 to rotate via the second transmission component 15. When the rotating shaft 1402 rotates, it can drive the crushing blade assembly 1403 and the spiral feeder 1404 to rotate. The rotation of the crushing blade assembly 1403 can crush the added enzyme-modified baking powder, which can prevent the moisture-affected enzyme-modified baking powder from clumping together and affecting the drying process. When the spiral feeder 1404 rotates, it can not only precisely control the feeding speed of the enzyme-modified baking powder, but also effectively prevent the discharge port 1406 from being blocked, thus affecting the enzyme-modified baking process. During normal powder feeding, the guiding and conveying module 5 conveys hot air while simultaneously driving the cleaning component 13 to rotate. The cleaning component 13 cleans the bottom of the modified starch filtration module 7, preventing the filter holes at the bottom of the modified starch filtration module 7 from being blocked by the enzyme-modified starch, thus affecting normal filtration and the discharge of hot air. At the same time, the vibration module 12, in conjunction with the stirring module 4, drives the guiding and conveying module 5 to vibrate, further preventing the filter holes at the bottom of the modified starch filtration module 7 from being blocked by the enzyme-modified starch. This effectively increases the discharge efficiency of hot air and improves the efficiency of the secondary hot air drying of the enzyme-modified starch by the recovered hot air.
