Description

Technical Field

[0001] The invention belongs to the technical field of curdlan production, and in particular relates to a drying device and a method for preparing curdlan. Background Art

[0002] As an important microbial polysaccharide, curdlan has broad application prospects in food, medicine, chemical industry and other fields. With the continuous growth of its market demand, different requirements are also put forward for the production quality of curdlan.

[0003] Hot air drying is a commonly used drying method, which removes moisture by blowing hot air across the surface of the material; however, this method has the problem of uneven drying; since the distribution of hot air in the drying chamber is difficult to be completely uniform, the heating and water loss of different parts of the curdlan during the drying process are inconsistent, and some areas may be over-dried, resulting in reduced product quality.

[0004] The Chinese utility model patent with patent application number: CN202022875768.7 discloses a drying equipment for processing shiitake mushrooms, including a drying box body, wherein a plurality of placement racks are hingedly connected linearly and equidistantly in the vertical direction inside the drying box body, and a motor is fixedly installed on one side of the outer wall of the drying box body near the upper end, and one end of the motor is rotatably connected to a turntable, the turntable is located on the upper side of the inner wall of the drying box body, and the end face of the turntable is hinged with a hinged rod, one end of the hinged rod is hinged to one side of the end face of the placement rack, and the side wall of the placement rack is slidably connected with a shiitake mushroom placement plate, and the two side walls of the two placement racks are hinged with transmission rods.

[0005] The above-mentioned existing drying box can dry the materials to be dried. When in use, the motor drives the turntable to drive the hinged rod to rotate eccentrically, and the hinged rod drives the placement rack to swing. Through the cooperation of multiple transmission rods, multiple placement racks are swung synchronously, shaking the materials on the placement racks to improve the drying effect.

[0006] However, with environmental protection requirements becoming increasingly stringent today, traditional drying methods also face challenges in waste gas treatment. For example, the waste gas generated by hot air drying may contain a small amount of curing gum volatiles, water vapor and other organic impurities. If it is discharged directly, it will pollute the atmospheric environment and will not meet the requirements of environmental protection regulations. Therefore, it is necessary to configure external waste gas treatment facilities in the drying process to treat the waste gas generated during the drying process, which greatly increases the production cost and reduces the use effect.

[0007] Moreover, this type of existing drying oven cannot fully utilize high-temperature air, which reduces the use effect and increases energy consumption. Moreover, this type of drying oven can only dry one state of curd rubber in one drying process. When curd rubber in multiple states needs to be dried simultaneously, curd rubber with different requirements needs to be dried in batches, which reduces the use effect and cannot meet the drying requirements of different production stages and processes. Multiple drying equipment needs to be switched and used, which complicates the production process. Summary of the invention

[0018] The present invention also provides a drying method for preparing and producing curdlan, based on the above-mentioned drying device for preparing and producing curdlan, comprising the following steps: Step 1: according to different drying requirements of curdlan, the curdlan to be dried is respectively loaded into the shaking table in the high temperature zone and the low temperature zone; Step 2: When drying begins, start the first air pump to extract external air and deliver it to the heating chamber. The heating chamber is used to quickly heat the air to a set temperature value to meet the high-temperature drying requirements of the curdlan. The high-temperature air output from the heating chamber enters each upper coil and is then evenly sprayed onto the surface of the curdlan on the shaking table in the high-temperature zone through a nozzle to ensure efficient and uniform heating, thereby causing the water in the curdlan to evaporate quickly. At this time, the high-temperature zone is filled with high-temperature air. Step 3: The second air pump of the purification mechanism works to extract the high-temperature gas containing harmful substances such as water vapor and a small amount of colloidal volatiles in the high-temperature zone, and transport it to the aeration pipe in the purification chamber.

At this time, the movement of the through-trough body drives the shaking table in the low-temperature zone to swing through the cooperation of the first connecting plate and the first auxiliary shaft, so that the curd in the low-temperature zone is constantly shaken, thereby improving the drying effect; Step 5: When the first connecting plate moves, it drives the connecting shaft to move synchronously. The movement of the connecting shaft drives the shaking table in the high temperature zone to swing through the cooperation of the second connecting plate and the second auxiliary shaft, so that the curd in the high temperature zone shakes continuously, thereby improving the drying effect.

[0019] The present invention adopts the above technical solution and has the following beneficial effects: 1. The present invention is provided with a high temperature zone and a low temperature zone. The high temperature zone uses the high temperature air generated by the heating mechanism to quickly evaporate the moisture of the curdlan, thereby realizing efficient drying treatment. The purification mechanism introduces the high temperature gas from the high temperature zone into the low temperature zone after purification treatment, and uses the waste heat to further dry the curdlan in the low temperature zone, thereby making full use of energy and reducing overall energy consumption.

[0020] 2. The aeration pipe in the purification mechanism of the present invention can make the high-temperature gas fully contact with the purification liquid, so that the purification liquid can intercept, absorb or dissolve the harmful substances in the high-temperature gas, thereby purifying the high-temperature gas. The temperature of the purified high-temperature gas is reduced and enters the exhaust chamber after being filtered by the filter plate, and then is transported to the lower coil through the extension pipe and evenly sprayed into the low-temperature zone through the nozzle, thereby drying the curd on the shaking table in the low-temperature zone and making full use of the high-temperature gas discharged from the high-temperature zone.

[0021] 3. The present invention can simultaneously dry and process curdlan in different states in the same drying oven; the high-temperature zone can process curdlan with a high water content and a relatively wet initial state, so that the high-temperature gas in the high-temperature zone can quickly remove a large amount of moisture in the curdlan; the low-temperature zone can process curdlan that has undergone preliminary drying or requires further refined drying, and adjust its drying degree and state; thereby, the adaptability and scope of use of the drying device can be improved, and the drying requirements of different production stages and processes can be met, without the need to switch between multiple devices, thereby simplifying the production process and improving the flexibility and convenience of production.

[0022] 4. In the process of purifying and recycling the high-temperature gas, the present invention can not only dry and process the curdlan in different states at the same time, but also use the recycled high-temperature gas as a power to drive the shaking table in the high-temperature zone and the low-temperature zone, so that the shaking table shakes to vibrate the curdlan, thereby achieving a better curdlan drying effect.

[0029] The purification mechanism 6 drives the flipping mechanism 7 to work during operation. At this time, the flipping mechanism 7 works to shake the shaking table 4 in the low temperature area so that the curd on the shaking table 4 can be evenly mixed and fully contacted with the hot air to improve the drying effect.

[0030] The two side surfaces of the shaking table 4 are rotatably connected with fixed shafts 3 near the middle thereof, and the other end of the fixed shafts 3 is fixedly connected to the corresponding inner wall of the drying box 1 .

[0031] With such a design, the fixed shaft 3 can be used to support and place the rocking table 4, and the fixed shaft 3 can also be used to support the rocking table 4 for rocking, which is convenient to use.

[0032] The heating mechanism 5 comprises a heating chamber 501 , which is installed on the top of the drying box 1 , and an air inlet end of the heating chamber 501 is connected to a first air pump 502 , and an air inlet end of the first air pump 502 is connected to the external air.

[0033] A heating element (such as an electric heating wire) is arranged in the heating chamber 501 , and the heating element is used to quickly heat the air so that the temperature of the air is raised to a set temperature value.

[0034] The air outlet end of the heating chamber 501 passes through the drying box 1 and is connected to an upper coil 503. The upper coil 503 is composed of multiple groups, and the multiple groups of upper coils 503 are arranged on the inner wall of the high temperature zone.

[0035] In such a design, after the first air pump 502 is started, it is used to extract external air and transport it to the heating chamber 501; in the heating chamber 501, the air is quickly heated by a specific heating element (such as an electric heating wire) to increase the temperature of the air to a set temperature value to meet the thermal conditions required for drying the curdlan in the high temperature zone; the heated high-temperature air is transported to the high-temperature zone of the drying box 1 through the upper coil 503.

[0036] The upper coil 503 is a coil structure, and a plurality of holes 9 are formed on the outer surface of the upper coil 503 . The plurality of holes 9 are arranged at intervals, and nozzles 10 are respectively installed on the holes 9 .

[0037] With this design, the high-temperature air in the upper coil 503 is uniformly sprayed onto the shaking table 4 in the high-temperature zone through the holes 9 and the nozzles 10, thereby achieving uniform and efficient heating of the curdlan on the shaking table 4 in the high-temperature zone, so that the moisture in the curdlan can evaporate quickly under the action of high temperature, making it easy to use.

[0038] The purification mechanism 6 comprises a second air pump 601 , which is mounted on the outer wall of the drying box 1 , and an air inlet end of the second air pump 601 is connected to the high temperature zone.

[0039] The air outlet of the second air pump 601 is connected to the purification chamber 602 through a heat preservation pipe. The purification chamber 602 is installed on the outer wall of the drying box 1. The air outlet of the purification chamber 602 extends into the low temperature area.

[0040] An extension pipe 603 is provided in the low temperature zone, one end of the extension pipe 603 is connected to the gas outlet end of the purification chamber 602, and the other end of the extension pipe 603 is connected to multiple groups of lower coils 604, which are arranged on the inner wall of the low temperature zone.

[0041] In this design, the second air pump 601 is used to suck the high-temperature gas in the high-temperature zone. At this time, the high-temperature gas in the high-temperature zone contains water vapor and a small amount of colloidal volatiles and other harmful substances. The second air pump 601 transports the high-temperature gas to the purification chamber 602. The purification chamber 602 is used to filter, absorb or dissolve the water vapor and a small amount of colloidal volatiles and other harmful substances in the high-temperature gas to purify the high-temperature gas; the temperature of the purified high-temperature gas is reduced and enters the extension pipe 603, and then is transported to the low-temperature zone through the lower coil 604 to dry the curing agent on the shaking table 4 in the low-temperature zone.

[0042] In this embodiment, a plurality of holes 9 are also formed on the outer surface of the lower coil 604 . The plurality of holes 9 are arranged at intervals, and nozzles 10 are respectively installed on the holes 9 .

[0043] With this design, the purified hot air in the lower coil 604 is uniformly sprayed onto the shaking table 4 in the low temperature zone through the holes 9 and the nozzles 10, thereby achieving uniform and efficient heating of the curdlan on the shaking table 4 in the low temperature zone, so that the moisture in the curdlan can evaporate quickly under the action of high temperature, making it convenient to use.

[0044] In this embodiment, the high-temperature gas in the high-temperature zone is sucked into the purification chamber 602 by the second air pump 601. The high-temperature gas still has a certain temperature after being purified in the purification chamber 602. At this time, the hot air is transported to the low-temperature zone by the lower coil 604. At this time, the residual heat of the hot air can further dry the recyclable rubber in the low-temperature zone. On the other hand, the gas environment in the low-temperature zone can be renewed and circulated, so that the interior of the drying box 1 can simultaneously dry recyclable rubber in a variety of different states.

[0045] The flipping mechanism 7 includes a driving shaft 701, which is rotatably connected to the inside of the extension tube 603, and the axis of the driving shaft 701 is perpendicular to the axis of the extension tube 603. A plurality of annular blades 702 arranged at intervals are fixedly mounted on the outer surface of the driving shaft 701.

[0046] One end of the driving shaft 701 passes through the outer surface of the extension tube 603 and is fixedly connected to the flywheel 703. A rotating shaft 704 is installed on a side wall of the flywheel 703 away from the driving shaft 701. The rotating shaft 704 and the flywheel 703 are eccentrically arranged.

[0047] A synchronization component 8 is installed at the other end of the rotating shaft 704, and the synchronization component 8 is connected to the shaking table 4 in the low temperature zone.

[0048] The synchronization component 8 includes a first auxiliary shaft 801, one end of which is rotatably connected to the outer wall of the shaker 4 in the low-temperature zone close to the flywheel 703, and the other ends of multiple first auxiliary shafts 801 are rotatably connected to the same first connecting plate 802, which is arranged vertically.

[0049] A through slot body 803 is integrally connected to the first connecting plate 802 at a position close to the rotating shaft 704 . A square slot is defined in the through slot body 803 . The square slot passes through two side surfaces of the through slot body 803 .

[0050] One end of the rotating shaft 704 away from the flywheel 703 is arranged in the middle of the square groove of the through groove body 803 .

[0051] A groove 805 is formed on the inner surface of the square groove of the through groove body 803 , and a roller 806 is rotatably connected to the outer surface of the rotating shaft 704 , and the roller 806 is slidably connected to the inside of the groove 805 .

[0052] A second auxiliary shaft 807 is rotatably connected to the outer wall of the shaking table 4 in the high temperature zone near the flywheel 703. The other ends of the multiple second auxiliary shafts 807 are rotatably connected to the same second connecting plate 808. The middle position of the second connecting plate 808 is rotatably connected to the connecting shaft 804.

[0053] The lower end of the connecting shaft 804 slides through the heat insulation board 2 and is connected to a side surface of the first connecting board 802 .

[0054] With this design, the purified gas will impact the blades 702 on the outer wall of the drive shaft 701 when flowing in the extension tube 603, causing the drive shaft 701 to rotate, and the drive shaft 701 drives the flywheel 703 to rotate synchronously, and the flywheel 703 drives the rotating shaft 704 to rotate eccentrically, and the rotation of the rotating shaft 704 drives the through-groove body 803 to move. At this time, the through-groove body 803 drives the shaking table 4 in the low-temperature zone to swing through the transmission action of the first connecting plate 802 and the first auxiliary shaft 801, so that the colloidal silica in the low-temperature zone is continuously shaken, thereby improving the drying effect.

[0055] The first connecting plate 802 drives the connecting shaft 804 to move synchronously when moving. The movement of the connecting shaft 804 drives the shaking table 4 in the high temperature zone to swing through the transmission effect of the second connecting plate 808 and the second auxiliary shaft 807, so that the curd in the high temperature zone is constantly shaken, thereby improving the drying effect.

[0056] In this embodiment, the shaking table 4 in the high temperature zone and the shaking table 4 in the low temperature zone can swing synchronously, so that the curd placed on the shaking table 4 can continuously roll and vibrate, so that the curd is heated evenly, the drying effect is improved, and local overheating or uneven drying of the curd during the drying process is avoided.

[0057] A middle partition 605 is installed inside the purification chamber 602, and a vent is opened at the upper end of the middle partition 605, and a filter plate 608 is fixedly installed at the vent.

[0058] The middle partition 605 divides the inner cavity of the purification chamber 602 into a purification chamber 606 and an exhaust chamber 607 , and the purification chamber 606 and the exhaust chamber 607 are connected through a filter plate 608 .

[0059] The purification chamber 606 contains a purification liquid, which uses a high-boiling-point low-vapor filtered oil body. The purification liquid is used to intercept, absorb or dissolve harmful substances (such as organic volatiles) in the high-temperature gas entering the purification chamber 606.

[0060] In this embodiment, the high boiling point low steam filter oil body is a prior art, and the high boiling point low steam filter oil body has a high boiling point, and the temperature of the high temperature gas will not heat the purified liquid to boiling to generate steam.

[0061] An aeration pipe 609 is arranged in the purification chamber 606 below the liquid surface of the purified liquid, and a plurality of aeration holes are arranged at intervals on the aeration pipe 609 .

[0062] In this embodiment, one end of the aeration pipe 609 is a closed surface, the other end of the aeration pipe 609 is connected to the air outlet of the second air pump 601 , and one end of the extension pipe 603 close to the purification chamber 602 is connected to the exhaust chamber 607 .

[0063] In this embodiment, the aeration pipe 609 is further connected in series with an electromagnetic switch valve 610 , which is used to control the on-off of the aeration pipe 609 to prevent the purified liquid from flowing out through the aeration pipe 609 .

[0064] Designed in this way, the working principle of the purification mechanism 6 is: the second air pump 601 is used to suck the high-temperature gas in the high-temperature zone and send it to the aeration pipe 609, and the aeration holes on the aeration pipe 609 discharge the high-temperature gas. At this time, the high-temperature gas contacts with the purification liquid, which is used to intercept, absorb or dissolve harmful substances (such as organic volatiles) in the high-temperature gas, which is convenient for use.

[0065] Then the purified high-temperature gas enters the exhaust chamber 607 through the filter plate 608. At this time, the filter plate 608 is used to filter the purified high-temperature gas and intercept the moisture in the purified high-temperature gas for easy use. The temperature of the high-temperature air in the exhaust chamber 607 is lower than that of the high-temperature gas in the high-temperature zone. The high-temperature air in the exhaust chamber 607 is transported to the extension pipe 603, and the high-temperature air in the extension pipe 603 is transported to the low-temperature zone through the lower coil 604, so as to realize the drying of the curing agent on the shaking table 4 in the low-temperature zone.

[0066] In this embodiment, the purification liquid contained in the purification chamber 606 adopts a high-boiling-point low-steam filtered oil body, and the boiling point temperature of the oil body is greater than the working temperature of the drying device during operation. The oil body itself is not easy to volatilize, and can be stably stored in the purification bin 602 and continue to play a purification role, ensuring that the purified gas meets the requirements for reuse in the low-temperature zone drying. After the high-temperature gas with impurities in the high-temperature zone is purified by the oil body inside the purification bin 602, the high-temperature gas is converted into a pure gas with a slightly lower temperature. This part of the gas is transmitted into the low-temperature zone. On the one hand, the waste heat of the purified gas is used to further dry the curing agent in the low-temperature zone. On the other hand, the gas environment in the low-temperature zone is updated and circulated, so that the interior of the drying box 1 can simultaneously dry curing agent in different states, which is convenient for use.

[0067] In addition to this embodiment, in order to ensure the flow speed of the purified gas in the extension tube 603, a third air pump can also be connected in series to the extension tube 603. The third air pump is used to pressurize the purified gas flowing in the extension tube 603 to accelerate the flow speed of the purified gas.

[0068] The front side of the drying box 1 is hinged with a switch door, which is used to open or close the inner cavity of the drying box 1, thereby facilitating the taking and placing of the dried curdlan.

[0069] The present invention also provides a drying method for preparing and producing curdlan. Based on the above-mentioned drying device for preparing and producing curdlan, the drying method comprises the following steps: Step 1: according to different drying requirements of curdlan, the curdlan to be dried is respectively loaded into the shaking tables 4 in the high temperature zone and the low temperature zone, and then the switch door on the drying box 1 is closed to seal the inner cavity of the drying box 1.

[0070] Step 2: When drying begins, start the first air pump 502 to extract external air and transport it to the heating chamber 501. The heating chamber 501 is used to quickly heat the air to a set temperature value to meet the high-temperature drying requirements of the curdlan. The high-temperature air output by the heating chamber 501 enters each upper coil 503, and then is evenly sprayed onto the surface of the curdlan on the shaking table 4 in the high-temperature zone through the nozzle 10, ensuring efficient and uniform heating, and promoting rapid evaporation of moisture in the curdlan. At this time, the high-temperature zone is filled with high-temperature air.

[0071] Step three: The second air pump 601 of the purification mechanism 6 works to extract the high-temperature gas containing harmful substances such as water vapor and a small amount of colloidal volatiles in the high-temperature zone and transport it to the purification chamber 602; at this time, after the high-temperature gas enters the purification chamber 602, the harmful substances in the high-temperature gas are absorbed or dissolved when the high-temperature gas passes through the area containing the purification liquid; the temperature of the high-temperature gas after purification is reduced and enters the extension pipe 603, and then it is transported to the lower coil 604 and evenly sprayed into the low-temperature zone through the nozzle 10, so as to achieve the drying of the curing agent on the shaking table 4 in the low-temperature zone.

[0072] Step 4: When the purified gas flows in the extension tube 603, it will impact the blades 702 on the outer wall of the drive shaft 701, causing the drive shaft 701 to rotate, and the drive shaft 701 drives the flywheel 703 to rotate synchronously, and the flywheel 703 drives the rotating shaft 704 to rotate eccentrically, and the rotation of the rotating shaft 704 drives the through-groove body 803 to move. At this time, the movement of the through-groove body 803 drives the shaking table 4 in the low-temperature zone to swing through the cooperation of the first connecting plate 802 and the first auxiliary shaft 801, so that the curing agent in the low-temperature zone is continuously shaken, thereby improving the drying effect.

[0073] Step 5: When the first connecting plate 802 moves, it drives the connecting shaft 804 to move synchronously. The movement of the connecting shaft 804 drives the shaking table 4 in the high temperature zone to swing through the cooperation of the second connecting plate 808 and the second auxiliary shaft 807, so that the curing agent in the high temperature zone is constantly shaken to improve the drying effect.

[0074] In this embodiment, the high-temperature gas in the high-temperature zone is sucked into the purification chamber 602 by the second air pump 601. The high-temperature gas still has a certain temperature after being purified in the purification chamber 602. At this time, the hot air is transported to the low-temperature zone by the lower coil 604. At this time, the residual heat of the hot air can further dry the recyclable rubber in the low-temperature zone. On the other hand, the gas environment in the low-temperature zone can be renewed and circulated, so that the interior of the drying box 1 can simultaneously dry recyclable rubber in a variety of different states.

[0075] The upper coil 503 can ensure the drying efficiency and uniformity of the high temperature zone, and the lower coil 604 can optimize the drying effect of the low temperature zone, thereby improving the drying quality and efficiency of curdlan during the preparation and production process and improving the use effect.

[0076] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
