Description

Technical Field

[0001] This invention relates to the field of konjac production equipment technology, specifically to a coupled processing equipment and method for konjac with low-temperature gradient enzyme inactivation and activity stabilization. Background Technology

[0002] Konjac is a perennial herbaceous plant belonging to the genus Amorphophallus in the family Araceae. Its tuber is the main part used and is rich in unique components such as glucomannan. It has extremely high edible, medicinal and industrial value. In the process of konjac production, it is necessary to carry out low-temperature enzyme inactivation and activity stabilization operations. Therefore, coupled processing equipment is required to achieve the corresponding operations.

[0003] Traditional enzyme inactivation equipment often directly raises the temperature to the enzyme inactivation temperature to inactivate the enzymes in konjac. While this method effectively inactivates the enzymes, the high temperature causes the konjac's own substances to lose their activity, thus affecting its edible value and presenting certain limitations. Furthermore, the subsequent activity stabilization of the konjac requires separate equipment for mixing and stirring, increasing production costs. Summary of the Invention

[0012] As a preferred embodiment of the present invention: the outer wall of the first bevel gear meshes with the outer wall of the second bevel gear, the outer wall of the driven sprocket meshes with the outer wall of the drive chain, and the top of the spreading disc corresponds to the bottom of the feeding plate.

[0013] As a preferred embodiment of the present invention: the two ends of the outer wall of the heat-conducting pipe are respectively connected to the outer walls of the inlet pipe and the outlet pipe, and the power output shaft of the drive motor is connected to the outer wall of the stirring shaft.

[0014] A method for a coupled processing device for konjac with low-temperature gradient enzyme inactivation and activity stabilization includes the following steps:

[0015] S1: When it is necessary to perform low-temperature enzyme inactivation on konjac, the temperature needs to be maintained at a gradient increase, so that the temperature in the inner cavity of the mixing tank rises from 20 degrees Celsius to 35 degrees Celsius, and then from 35 degrees Celsius to 50 degrees Celsius, in order to perform low-temperature gradient enzyme inactivation on konjac. First, warm water at 20 degrees Celsius is introduced into the inner cavity of the water inlet chamber through the No. 2 water outlet pipe. At this time, the water inlet tank in the inner cavity of the rotating plate is connected to the guide tank, so that the water at 20 degrees Celsius enters the inner cavity of the heat conduction pipe, thereby raising the temperature of the konjac in the inner cavity of the mixing tank to 20 degrees Celsius.

[0016] S2: Subsequently, the temperature inside the mixing tank needs to be gradually increased to raise the temperature of the konjac inside the mixing tank to 35 degrees Celsius. At this time, the rotating plate is rotated in the inner cavity of the water inlet chamber, so that the position of the water inlet tank corresponds to that of the No. 3 water outlet pipe. The inner cavity of the water inlet tank will be connected to the inner cavity of the No. 3 water outlet pipe. At this time, water at 50 degrees Celsius can be introduced into the inner cavity of the water inlet chamber under the action of the No. 3 water outlet pipe. Under the control of the metering pump, the amount of water introduced is equal to the amount of water at 20 degrees Celsius introduced into the No. 2 water outlet pipe. With the water at 50 degrees Celsius neutralized, the water in the inner cavity of the heat conduction pipe will be at 35 degrees Celsius, so that the konjac inside the mixing tank is at the condition of 35 degrees Celsius.

[0017] S3: Raise the temperature inside the mixing tank again, and rotate the rotating plate so that the position of the water inlet tank corresponds to the position of the No. 1 water outlet pipe. The temperature inside the mixing tank needs to be raised to 50 degrees Celsius. At this time, the temperature of the water inside the mixing tank is 35 degrees Celsius. Water at 65 degrees Celsius is introduced into the inner cavity of the water inlet chamber through the No. 1 water outlet pipe. The amount of water introduced at this time is the sum of the amounts of water introduced in the previous two times, so that the water is fully mixed and water at 50 degrees Celsius is obtained. This achieves a stepwise increase in the temperature inside the mixing tank to inactivate the enzymes in the konjac inside the mixing tank.

[0018] S4: Next, an active stabilizer needs to be added to the inner cavity of the mixing tank. The active stabilizer is added to the inner cavity of the feeding hopper, and the amount of active stabilizer added to the inner cavity of the mixing tank is calculated based on the capacity of the inner cavity of the feeding hopper. The amount of active additive obtained by the feeding roller in one revolution is then calculated based on the capacity of the inner cavity of the feeding hopper. Thus, the feeding roller is rotated the corresponding number of revolutions under the drive of the servo motor to quantitatively add active additive to the inner cavity of the mixing tank.

[0019] S5: As the feeding roller rotates, it drives the drive sprocket to rotate. Under the transmission of the drive chain, the driven sprocket rotates, and under the action of the second bevel gear, it drives the first bevel gear, causing the spreading disc to rotate in the inner cavity of the mixing tank. When the spreading disc rotates, it spreads the active stabilizer from the feeding plate outward, so that the active additive comes into more uniform contact with the konjac, thereby completing the enzyme inactivation and activity stabilization of the konjac.

[0020] The present invention has the following beneficial effects:

[0021] 1. The coupled processing equipment and method for low-temperature gradient enzyme inactivation and activity stabilization of konjac utilizes a rotating plate installed in the inner cavity of the water inlet chamber. By rotating the rotating plate, water outlet pipes No. 1, No. 2, and No. 3 are connected to the water inlet chamber, thereby supplying water of different temperatures to the water inlet chamber and water outlet pipes. This allows the temperature in the inner cavity of the heat-conducting pipe to rise in a gradient. As the temperature rises in a gradient, low-temperature gradient enzyme inactivation of konjac in the inner cavity of the mixing tank is achieved without raising the temperature too high at once, thus avoiding damage to the effective components of konjac.

[0022] 2. The coupled processing equipment and method for low-temperature gradient enzyme inactivation and activity stabilization of konjac utilizes a feeding hopper set on the top of the top cover and a feeding roller set in the inner cavity of the feeding hopper. As the feeding roller rotates, the activity stabilizer is released to the feeding plate, and under the action of the rotating spreading disc, the activity stabilizer is evenly spread into the inner cavity of the mixing tank, so that the activity stabilizer can be well mixed with konjac evenly under the premise of quantitative addition.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1 - Figure 11 A coupled processing device for low-temperature gradient enzyme inactivation and activity stabilization of konjac includes a mixing tank 1, a support platform 2 installed at the bottom of the mixing tank 1, a heat-conducting pipe 3 installed in the inner cavity of the mixing tank 1, a water inlet component 4 and a drainage component 5 provided on the outer wall of the heat-conducting pipe 3, a top cover 6 installed on the top of the mixing tank 1, a feeding component 7 and a sprinkling component 8 provided on the top of the top cover 6, and a drive motor 9 fixedly mounted at the bottom of the mixing tank 1. A stirring shaft 10 is fixedly mounted on the power output shaft of the drive motor 9.

[0041] In the above structure, the drive motor 9 is installed at the bottom of the mixing tank 1, and the stirring shaft 10 is installed in the inner cavity of the mixing tank 1. By connecting the power output shaft of the drive motor 9 to the stirring shaft 10, the stirring shaft 10 is rotated under the action of the drive motor 9. The stirring shaft 10 stirs the konjac in the inner cavity of the mixing tank 1 and performs gradient heating to inactivate the enzymes in the konjac.

[0042] In a preferred embodiment: the water inlet assembly 4 includes a water inlet chamber 401, an inlet pipe 402 fixedly mounted on the outer wall of the water inlet chamber 401, a sealing plate 407 installed on the outer wall of the water inlet chamber 401, a first outlet pipe 403 installed on the outer wall of the sealing plate 407, a metering pump 404 fixedly mounted on the outer wall of the first outlet pipe 403, a second outlet pipe 405 installed on the outer wall of the sealing plate 407, and a third outlet pipe 406 installed on the outer wall of the sealing plate 407. A fixing ring 408 is fixedly assembled on the wall. An indicator groove 409 is opened on the outer wall of the fixing ring 408. A guide groove 4010 is opened in the inner cavity of the water inlet chamber 401. A rotating plate 4011 is rotatably connected to the inner cavity of the water inlet chamber 401. A water inlet groove 4012 is opened in the inner cavity of the rotating plate 4011. A fixing pipe 4013 is fixedly assembled on the outer wall of the rotating plate 4011. A drive spring 4014 is installed in the inner cavity of the fixing pipe 4013. An indicator rod 4015 is movably sleeved in the inner cavity of the fixing pipe 4013.

[0043] In the above structure, the water inlet chamber 401 set on the outer wall of the heat pipe 3 allows warm water to be introduced into the inner cavity of the heat pipe 3. After entering the inner cavity of the heat pipe 3, the warm water raises the temperature of the konjac in the inner cavity of the mixing tank 1, thereby sterilizing the konjac at a low temperature. Furthermore, the first drain pipe 403, the second drain pipe 405, and the third drain pipe 406 set on the outer wall of the water inlet chamber 401, respectively, allow the rotating plate 4011 to rotate. This causes the water inlet tank 4012 in the inner cavity of the rotating plate 4011 to connect with the first drain pipe 403, the second drain pipe 405, and the third drain pipe 406, respectively. This supplies hot water of different temperatures into the inner cavity of the water inlet pipe 402, resulting in a gradient increase in temperature within the inner cavity of the heat pipe 3.

[0044] In a preferred embodiment: there are three guide grooves 4010, and the three guide grooves 4010 are respectively opened in the inner cavity of the water inlet chamber 401. The inner cavity of the water inlet groove 4012 is connected to the inner cavity of the water inlet pipe 402. The opening position of the indicator groove 409 corresponds to the opening position of the guide groove 4010. The two ends of the outer wall of the drive spring 4014 are in contact with the outer wall of the indicator rod 4015 and the inner wall of the fixing tube 4013, respectively. The drive spring 4014 is made of high carbon steel.

[0045] In the above structure, the water inlet groove 4012 opened in the inner cavity of the rotating plate 4011 allows the water inlet groove 4012 to communicate with the inner cavity of the guide groove 4010 when the rotating plate 4011 is rotated. This allows hot water in the pipe corresponding to the guide groove 4010 to be introduced into the inner cavity of the water inlet pipe 402. Under the action of the water inlet pipe 402, the hot water is introduced into the inner cavity of the heat conduction pipe 3, causing the temperature gradient in the inner cavity of the heat conduction pipe 3 to increase. When the rotating plate 4011 is rotated, the indicator rod 4015 will rotate along the inner wall of the fixed ring 408 and enter the indicator groove 409, thereby better judging the rotation angle of the rotating plate 4011.

[0046] In a preferred embodiment: the drainage assembly 5 includes a water outlet pipe 501, a fixed cylinder 502 is fixedly mounted on the outer wall of the water outlet pipe 501, a limit rod 503 is fixedly mounted on the inner wall of the fixed cylinder 502, a return spring 504 is movably sleeved on the outer wall of the limit rod 503, a movable plate 505 is movably sleeved on the outer wall of the limit rod 503, and a sealing plate 506 is fixedly mounted on the outer wall of the movable plate 505.

[0047] In the above structure, the water outlet pipe 501 provided on the outer wall of the heat pipe 3, and the movable plate 505 and the sealing plate 506 provided in the inner cavity of the water outlet pipe 501, under the drive of the return spring 504, will cause the sealing plate 506 to enter the inner cavity of the water outlet pipe 501, thereby sealing the inner cavity of the water outlet pipe 501 and preventing external debris from entering the inner cavity of the heat pipe 3.

[0048] In a preferred embodiment: the feeding assembly 7 includes a feeding bin 701, a feeding bin 702 is fixedly mounted at the bottom of the feeding bin 701, a feeding roller 703 is rotatably connected to the inner cavity of the feeding bin 702, a servo motor 704 is fixedly mounted at the top of the top cover 6, a feeding groove 706 is opened on the outer wall of the feeding roller 703, a feeding plate 705 is fixedly mounted at the bottom of the feeding bin 702, a drive sprocket 707 is fixedly mounted on the outer wall of the feeding roller 703, and a drive chain 708 is meshed on the outer wall of the drive sprocket 707;

[0049] In the above structure, the feeding bin 701 provided on the top of the top cover 6 and the picking bin 702 provided at the bottom of the feeding bin 701 drive the picking roller 703 to rotate under the action of the servo motor 704. Through the feeding groove 706 opened on the outer wall of the picking roller 703, the active stabilizer in the inner cavity of the feeding bin 701 can be added to the picking bin 702 during the rotation of the picking roller 703, and released into the inner cavity of the mixing tank 1 along the picking bin 702 and the feeding plate 705.

[0050] In a preferred embodiment: the power output shaft of the servo motor 704 is connected to the outer wall of the picking roller 703, the shape of the outer wall of the picking roller 703 matches the shape of the inner wall of the picking bin 702, and the inner cavity of the picking bin 702 communicates with the inner cavities of the feeding bin 701 and the feeding plate 705 respectively.

[0051] In the above structure, through the feeding groove 706 opened on the outer wall of the feeding roller 703, the active stabilizer in the inner cavity of the feeding bin 701 will enter the inner cavity of the feeding plate 705 and be added to the bottom of the spreading disc 802 under the action of the feeding plate 705. During the rotation of the spreading disc 802, the active stabilizer is rotated and spread into the inner cavity of the mixing tank 1, so that the active stabilizer can be added to the konjac in the inner cavity of the mixing tank 1 more evenly, so that the konjac can better contact the active stabilizer with the konjac.

[0052] In a preferred embodiment: the spreading assembly 8 includes a rotating rod 801, a spreading disc 802 is fixedly mounted on the outer wall of the rotating rod 801, a first bevel gear 803 is fixedly mounted on the top of the rotating rod 801, a second bevel gear 804 is rotatably connected to the top of the top cover 6, and a driven sprocket 805 is fixedly mounted on the outer wall of the second bevel gear 804.

[0053] In the above structure, the rotating rod 801 set in the inner cavity of the top cover 6 drives the drive sprocket 707 to rotate as the material taking roller 703 rotates. Under the action of the drive chain 708, the power is transmitted to the driven sprocket 805, so that the second bevel gear 804 rotates with the rotation of the driven sprocket 805, and drives the rotating rod 801 to rotate, so that the spreading disc 802 rotates in the inner cavity of the mixing tank 1. Under the action of the spreading disc 802, the active stabilizer is spread into the inner cavity of the mixing tank 1, so that the active stabilizer comes into more uniform contact with the konjac.

[0054] In a preferred embodiment: the outer wall of the first bevel gear 803 meshes with the outer wall of the second bevel gear 804, the outer wall of the driven sprocket 805 meshes with the outer wall of the drive chain 708, and the top of the spreading disc 802 corresponds to the bottom of the feeding plate 705.

[0055] In the above structure, by meshing the outer wall of the second bevel gear 804 with the outer wall of the first bevel gear 803, when the driven sprocket 805 rotates with the rotation of the drive sprocket 707, power can be transmitted to the second bevel gear 804, and the second bevel gear 804 drives the rotating rod 801, so that the rotating rod 801 rotates in the inner cavity of the mixing tank 1, so as to drive the spreading disc 802 and spread the active stabilizer evenly.

[0056] In a preferred embodiment: the two ends of the outer wall of the heat pipe 3 are connected to the outer walls of the water inlet pipe 402 and the water outlet pipe 501 respectively, and the power output shaft of the drive motor 9 is connected to the outer wall of the stirring shaft 10.

[0057] In the above structure, the stirring shaft 10 is installed in the inner cavity of the mixing tank 1, and the drive motor 9 is installed at the bottom of the mixing tank 1. The drive motor 9 drives the stirring shaft 10, so that the stirring shaft 10 rotates in the inner cavity of the mixing tank 1. The stirring shaft 10 continuously stirs the konjac in the inner cavity of the mixing tank 1, so that the konjac is fully mixed with the active stabilizer after the enzyme inactivation at low temperature is completed.

[0058] A method for a coupled processing device for konjac with low-temperature gradient enzyme inactivation and activity stabilization includes the following steps:

[0059] S1: When it is necessary to perform low-temperature enzyme inactivation on konjac, the temperature needs to be maintained at a gradient increase, so that the temperature in the inner cavity of mixing tank 1 rises from 20 degrees Celsius to 35 degrees Celsius, and then from 35 degrees Celsius to 50 degrees Celsius, so as to perform low-temperature gradient enzyme inactivation on konjac. First, warm water at 20 degrees Celsius is introduced into the inner cavity of water inlet chamber 401 through water outlet pipe 405. At this time, the water inlet tank 4012 in the inner cavity of rotating plate 4011 is connected to guide tank 4010, so that water at 20 degrees Celsius enters the inner cavity of heat conduction pipe 3, thereby raising the temperature of konjac in the inner cavity of mixing tank 1 to 20 degrees Celsius.

[0060] S2: Subsequently, the temperature inside the mixing tank 1 needs to be gradually increased to raise the temperature of the konjac inside the mixing tank 1 to 35 degrees Celsius. At this time, the rotating plate 4011 is rotated. The rotating plate 4011 rotates inside the water inlet chamber 401, so that the position of the water inlet tank 4012 corresponds to that of the third water outlet pipe 406. The inner cavity of the water inlet tank 4012 will be connected to the inner cavity of the third water outlet pipe 406. At this time, water at 50 degrees Celsius can be introduced into the inner cavity of the water inlet chamber 401 under the action of the third water outlet pipe 406. Under the control of the metering pump 404, the amount of water introduced is equal to the amount of water at 20 degrees Celsius introduced into the second water outlet pipe 405. With the water at 50 degrees Celsius neutralized, the water in the inner cavity of the heat conduction pipe 3 will be at 35 degrees Celsius, so that the konjac inside the mixing tank 1 is at the condition of 35 degrees Celsius.

[0061] S3: Raise the temperature in the inner cavity of mixing tank 1 again, and rotate the rotating plate 4011 so that the position of the water inlet tank 4012 corresponds to the position of the first water outlet pipe 403. The temperature in the inner cavity of mixing tank 1 needs to be raised to 50 degrees Celsius. At this time, the temperature of the water in the inner cavity of mixing tank 1 is 35 degrees Celsius. Water at 65 degrees Celsius is introduced into the inner cavity of the water inlet chamber 401 through the first water outlet pipe 403. The amount of water introduced at this time is the sum of the amounts of water introduced in the previous two times, so that the water is fully mixed and water at 50 degrees Celsius is obtained. This achieves a stepwise increase in the temperature in the inner cavity of mixing tank 1 to inactivate the enzymes in the konjac in the inner cavity of mixing tank 1.

[0062] S4: Subsequently, an active stabilizer needs to be added to the inner cavity of the mixing tank 1. The active stabilizer is added to the inner cavity of the feeding hopper 701, and the amount of active stabilizer added to the inner cavity of the mixing tank 1 is calculated based on the capacity of the inner cavity of the feeding trough 706. The amount of active additive obtained by the feeding roller 703 rotating once is then calculated based on the capacity of the inner cavity of the feeding trough 706. Thus, the feeding roller 703 is rotated the corresponding number of times under the drive of the servo motor 704 to quantitatively add active additive to the inner cavity of the mixing tank 1.

[0063] S5: As the feeding roller 703 rotates, it drives the drive sprocket 707 to rotate. Under the transmission of the drive chain 708, the driven sprocket 805 rotates and, under the action of the second bevel gear 804, drives the first bevel gear 803, causing the spreading disc 802 to rotate in the inner cavity of the mixing tank 1. When the spreading disc 802 rotates, it spreads the active stabilizer from the feeding plate 705 outward, so that the active additives come into more uniform contact with the konjac, thereby completing the enzyme inactivation and activity stabilization of the konjac.

7. The method for processing konjac using a coupled low-temperature gradient enzyme inactivation and activity stabilization processing device according to claim 6, characterized in that: Includes the following steps: S1: When it is necessary to perform low-temperature enzyme inactivation on konjac, the temperature needs to be maintained at a gradient increase so that the temperature in the inner cavity of the mixing tank (1) rises from 20 degrees Celsius to 35 degrees Celsius, and then from 35 degrees Celsius to 50 degrees Celsius to perform low-temperature gradient enzyme inactivation on konjac. First, warm water at 20 degrees Celsius is introduced into the inner cavity of the water inlet chamber (401) through the second water outlet pipe (405). At this time, the water inlet tank (4012) in the inner cavity of the rotating plate (4011) is connected to the guide tank (4010), so that the water at 20 degrees Celsius enters the inner cavity of the heat conduction pipe (3), thereby raising the temperature of the konjac in the inner cavity of the mixing tank (1) to 20 degrees Celsius. S2: Subsequently, the temperature inside the mixing tank (1) needs to be gradually increased to raise the temperature of the konjac inside the mixing tank (1) to 35 degrees Celsius. At this time, rotate the rotating plate (4011). The rotating plate (4011) rotates inside the water inlet chamber (401) so that the position of the water inlet tank (4012) corresponds to that of the third water outlet pipe (406). The inner cavity of the water inlet tank (4012) will be connected to the inner cavity of the third water outlet pipe (406). At this time, water at 50 degrees Celsius can be introduced into the inner cavity of the water inlet (401) under the action of the No. 3 water outlet pipe (406), and under the control of the metering pump (404), the amount of water introduced is equal to the amount of water at 20 degrees Celsius introduced into the No. 2 water outlet pipe (405). Under the neutralization of the water at 50 degrees Celsius, the water in the inner cavity of the heat conduction pipe (3) will be at 35 degrees Celsius, so that the konjac in the inner cavity of the mixing tank (1) is at the condition of 35 degrees Celsius. S3: Raise the temperature in the inner cavity of the mixing tank (1) again, and rotate the rotating plate (4011) so that the position of the water inlet tank (4012) corresponds to the position of the first water outlet pipe (403). The temperature in the inner cavity of the mixing tank (1) needs to be raised to fifty degrees Celsius. At this time, the temperature of the water in the inner cavity of the mixing tank (1) is thirty-five degrees Celsius. Water at sixty-five degrees Celsius is introduced into the inner cavity of the water inlet chamber (401) through the first water outlet pipe (403). The amount of water introduced at this time is the sum of the amount of water introduced in the previous two times, so that the water is fully mixed and fifty degrees Celsius water is obtained. The temperature in the inner cavity of the mixing tank (1) is raised in stages to inactivate the enzymes of the konjac in the inner cavity of the mixing tank (1). S4: Subsequently, an active stabilizer needs to be added to the inner cavity of the mixing tank (1). The active stabilizer is added to the inner cavity of the feeding hopper (701), and the amount of active stabilizer added to the inner cavity of the mixing tank (1) is calculated based on the capacity of the inner cavity of the feeding trough (706). Thus, under the drive of the servo motor (704), the feeding roller (703) rotates the corresponding number of times to quantitatively add the active additive to the inner cavity of the mixing tank (1). S5: As the feeding roller (703) rotates, it drives the drive sprocket (707) to rotate, which in turn drives the driven sprocket (805) to rotate under the transmission of the drive chain (708). The driven sprocket (805) is driven by the second bevel gear (804) to drive the first bevel gear (803), which causes the spreading disc (802) to rotate in the inner cavity of the mixing tank (1). When the spreading disc (802) rotates, it spreads the active stabilizer out of the feeding plate (705) to the outside, so that the active additives come into contact with the konjac more evenly, thereby completing the enzyme inactivation and activity stabilization of the konjac.
