Description

Technical Field

[0001] The invention relates to the technical field of Chinese herbal medicine slice production equipment, in particular to fermentation equipment for Chinese herbal medicine slice production and a fermentation method for processing pinellia tuber. Background Art

[0002] Chinese herbal medicines are processed according to the theory and processing methods of traditional Chinese medicine and can be directly used in clinical Chinese medicine. Banxiaqu is a special dosage form of Chinese medicine in the classification of Chinese herbal medicines, and its production process involves food fermentation. When making Banxiaqu, the pinellia or the processed pinellia is ground into powder, and then flour and other ingredients are added to mix and fermented. This process needs to be carried out under aerobic conditions to ensure that the microorganisms can fully grow and reproduce to produce various aroma substances and other effective ingredients in Banxiaqu.

[0003] In a Chinese patent with publication number CN113106002B, a pollution-proof fermentation machine for Chinese herbal medicine slices and a working method thereof are disclosed. By setting a pre-treatment box, the gas entering the fermentation chamber can be treated to prevent bacteria from contaminating the fermentation product.

[0004] In order to achieve better heat conduction and temperature control effects, the above-mentioned fermentation machine is provided with a heating jacket and a threaded protrusion. By arranging a partition strip that spirals up along the cylinder wall in the heating jacket, the flow of the heating liquid is increased, thereby improving the heat exchange efficiency. However, since this method has a long heat exchange stroke, in order to ensure that the temperatures of the upper and lower ends are close, a faster liquid flow rate is required, that is, a larger liquid pressure needs to be provided, and therefore, a higher power consumption is required. At the same time, an air vent is provided on the stirring paddle provided in the above-mentioned device. Since the pressure on the air vent varies with the increase in the depth of the fermentation product in the fermentation chamber, the air outlet on the stirring paddle at the bottom has a small air output, which makes it difficult to promote the movement and mixing of the surrounding fermented materials, resulting in insufficient stirring effect of the stirring device and difficulty in quickly stirring the fermented materials evenly.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Embodiment 1

[0052] See also Figure 1 - Figure 3The present invention provides a fermentation device for producing Chinese herbal medicine slices, comprising a tank body 1, a tank cover 2 is installed on the upper end of the tank body 1, a spiral feeding mechanism 3, a stirring mechanism 4 and a defoaming mechanism 5 are installed inside the tank body 1, the spiral feeding mechanism 3 comprises a straight tube 31, a spiral auger 32 and an auger shaft 33, the straight tube 31 is fixedly installed inside the tank body 1, the spiral auger 32 is sleeved inside the straight tube 31, and the spiral auger 32 is fixedly installed on the auger shaft 33, the auger shaft 33 is rotatably installed inside the straight tube 31, the outer surface of the spiral feeding mechanism 3 is provided with a temperature control tube 6, both ends of the temperature control tube 6 are penetrated to the outside of the tank body 1, the stirring mechanism 4 comprises an upper rod 41, a lower rod 42 and an upper and lower reciprocating component 43, the upper rod 41 is rotatably installed inside the tank body 1, the upper end of the lower rod 42 is slidably connected to the lower end of the upper rod 41, the upper and lower reciprocating component 43 includes a movable block 438, the movable block 438 is rotatably connected to the lower rod 42, and the movable block 438 reciprocates up and down as the upper rod 41 rotates, the defoaming mechanism 5 includes a defoaming rotating rod 51 and a defoaming plate 52, the defoaming rotating rod 51 is rotatably installed inside the tank body 1, the defoaming plate 52 is slidably installed on the defoaming rotating rod 51, and a driving motor 7 is installed on the top of the tank cover 2, and the driving end of the driving motor 7 drives the auger shaft 33, the upper rod 41 and the defoaming rotating rod 51 to rotate at different speeds through the driving mechanism 8.

[0053] As can be seen from the above, when using the fermentation equipment, the fermentation substrate is put into the fermentation equipment from the feed port 21, and then the sealing door is closed; atomized clean water is injected from the liquid inlet end of the annular spray pipe 22 to control the fermentation humidity inside the tank body 1, and according to the fermentation temperature of the fermentation substrate, water of suitable temperature is circulated into the temperature control tube 6 to change the temperature inside the tank body 1; then the drive motor 7 is started to make the drive mechanism 8 work, driving the auger shaft 33, the upper rod 41 and the defoaming rotating rod 51 to rotate at different speeds, so that the fermentation substrate of Pinellia ternata can be more fully mixed inside the tank body 1; after the fermentation is completed, the valve of the discharge port 11 is opened to allow the prepared viscous liquid fermentation product to flow out.

[0054] In addition, due to the provision of a spiral feeding mechanism 3, the fermentation substrate at the bottom of the tank body 1 can be transported to the top, and the provision of the stirring mechanism 4 can better mix the fermentation substrate. By providing a temperature control tube 6 wound around the straight tube 31, the temperature control tube 6 can control the temperature of the fermentation substrate transported inside the straight tube 31 and the fermentation substrate near the center of the fermentation tank. The water flow in the temperature control tube 6 is short, which reduces the power consumption of heat exchange and can better exchange heat, so that the fermentation temperature inside the fermentation equipment reaches a suitable fermentation temperature. At the same time, since an upper and lower reciprocating component 43 is provided in the stirring mechanism 4, when the movable block 438 reciprocates up and down as the upper rod 41 rotates, it brings The lower rod 42, which is rotatably connected to the movable block 438, moves back and forth up and down together. At the same time, since the upper end of the lower rod 42 is slidably connected to the lower end of the upper rod 41, when the upper rod 41 rotates, the lower rod 42 can rotate and move up and down at the same time, so that the stirring mechanism 4 can stir the fermentation substrate in a wider range, thereby being able to better mix the fermentation substrate; and, since the driving mechanism 8 can make the auger shaft 33, the upper rod 41 and the defoaming rotating rod 51 rotate at different speeds, the auger shaft 33 and the defoaming rotating rod 51 can be prevented from rotating too fast, resulting in severe heating inside the fermentation equipment due to excessive mechanical movement, thereby adversely affecting the control of the fermentation temperature.

[0055] Embodiment 2

[0056] like Figure 4 - Figure 7 and Fig. 9 - Fig.12 As shown, the difference between this embodiment and the above embodiment is that a guide slot 411 is provided at the lower end of the upper rod 41, a connecting rod 421 is fixedly installed at the upper end of the lower rod 42, a guide slider 422 is fixedly installed at the upper end of the connecting rod 421, and the guide slider 422 is slidably installed in the guide slot 411, and the upper and lower reciprocating components 43 include a sealing box 431, which is fixedly installed in the tank body 1, and a cam 432 is rotatably installed on one side of the sealing box 431, and an oblique ring groove 433 is provided on the side of the cam 432, and a swing ring 434 rotatably connected to the oblique ring groove 433 is sleeved on the oblique ring groove 433, and the swing ring 434 is rotatably connected to the swing ring 434. A round rod 435 is fixedly installed on one end of 34, a pin 436 is movably provided on one end of the round rod 435, the pin 436 is rotatably installed inside the movable block 438, and a telescopic slide groove 437 adapted to the round rod 435 is opened on one side of the pin 436, a rotating block 423 is fixedly installed on the connecting rod 421, a connecting block 424 is rotatably connected to the rotating block 423, one end of the connecting block 424 is fixedly connected to the side of the movable block 438, sealing rings 439 are respectively provided at the connection positions of the sealing box 431 and the upper rod 41 and the lower rod 42, and the lower end of the upper rod 41 and the upper end of the cam 432 are connected through a transmission pulley 47.

[0057] As can be seen from the above, by providing the guide slide groove 411, the connecting rod 421 and the guide slider 422, since the guide slider 422 fixedly installed on the upper end of the lower rod 42 through the connecting rod 421 is slidably connected with the guide slide groove 411 provided at the bottom of the upper rod 41, the lower rod 42 can rotate with the upper rod 41 and can also move up and down within a certain range; since the movable block 438 is rotatably connected to the lower rod 42 through the rotating block 423, when the movable block 438 moves up and down, it will drive the lower rod 42 to move up and down; since the oblique ring groove 433 provided on the cam 432 is rotatably connected to the swing ring 434, therefore, the lower rod 42 can be fixedly installed on the swing ring 434. The end of the round rod 435 at one end of the ring 434 away from the swing ring 434 can change its height as the swing ring 434 rotates on the oblique ring groove 433. At the same time, since the cam 432 is rotatably installed inside the sealing box 431, the round rod 435 can be made to swing up and down in a vertical plane by rotating the cam 432 and restricting the swing ring 434 from rotating. At this time, the end of the round rod 435 away from the swing ring 434 makes an arc motion; and since the round rod 435 is slidably connected to the pin 436 through the telescopic slide groove 437, and the pin 436 is rotatably installed inside the movable block 438, the round rod 435 is affected by the The upper rod 41 is restricted in different directions by the cam 432 and the movable block 438 and cannot rotate. Therefore, when the cam 432 rotates, the round rod 435 drives the movable block 438 to move up and down, thereby driving the lower rod 42 to reciprocate up and down. In addition, since the upper rod 41 and the cam 432 are connected by the transmission pulley 47, when the upper rod 41 rotates, it can also drive the cam 432 to rotate. Therefore, under the action of the up and down reciprocating component 43, when the upper rod 41 rotates, it drives the lower rod 42 to rotate and also makes the lower rod 42 reciprocate up and down, so that the upper stirring blade 44 and the lower stirring blade 45 can move up and down while rotating. The stirring blades 42 are movable, thereby expanding the stirring range of a single stirring blade and avoiding the slow flow rate of the fermented product between two adjacent stirring blades. Without adding an additional power structure to the inside of the tank body 1, the stirring blades can rotate and move up and down, and the up and down reciprocating components 43 that drive the stirring blades to move are arranged above the liquid level of the fermented product inside the tank body 1, which is not easily contaminated by the fermented product and thus hindered in movement. The transmission pulley 47 mentioned in this embodiment is a transmission mechanism commonly used in the prior art, including a transmission wheel and a transmission belt structure. By setting the diameters of the two transmission wheels to be different, the speed of the up and down reciprocating movement of the lower rod 42 can be changed.

[0058] Embodiment 3

[0059] like Figure 2 , Figure 4 and Fig.11As shown, the difference between this embodiment and the above embodiment is that an upper stirring blade 44 and a lower stirring blade 45 are fixedly mounted on the lower rod 42, the upper stirring blade 44 is arranged on the side of the straight tube 31, and the lower stirring blade 45 is arranged below the straight tube 31, and the length of the lower stirring blade 45 is greater than the length of the upper stirring blade 44.

[0060] As can be seen from the above, the upper stirring blades 44 can stir the fermentation bottom on the side of the straight tube 31 , and the lower stirring blades 45 can stir the fermentation substrate below the straight tube 31 .

[0061] A pressure plate 46 is fixedly mounted on the lower end of the lower rod 42 , and a stirring blade 461 is disposed on the outer side of the pressure plate 46 . The pressure plate 46 is disposed below the lower stirring blade 45 and close to the upper end of the discharge port 11 .

[0062] As can be seen from the above, by setting the pressure plate 46, when the lower rod 42 reciprocates up and down, the bottom of the pressure plate 46 squeezes the fermentation substrate downward or sucks the fermentation substrate upward, so that the pressure of the tank body 1 near the discharge port 11 can be continuously changed, making the discharge port 11 not easily blocked. At the same time, the setting of the stirring piece 461 makes the pressure plate 46 also have a stirring effect.

[0063] A discharge port 11 is provided at the bottom of the tank body 1, and a valve is provided on the discharge port 11. A sight glass 12 is also provided on one side of the tank body 1. An annular ventilation pipe 13 is installed at the inner bottom of the tank body 1. The air inlet end of the annular ventilation pipe 13 penetrates the inner wall of the tank body 1 and extends to the outside of the tank body 1, and the jet end of the annular ventilation pipe 13 is evenly arranged on the lower surface of the ring. The annular ventilation pipe 13 is arranged between the lower stirring blade 45 and the pressure plate 46. A feed port 21 is installed on one side of the tank cover 2, and a sealing door is provided on the feed port 21. An annular spray pipe 22 is provided inside the tank cover 2, and the liquid inlet end of the annular spray pipe 22 penetrates the inner wall of the tank cover 2 and extends to the outside of the tank cover 2.

[0064] As can be seen from the above, by setting the discharge port 11 and the valve, the fermented material is discharged, by setting the sight glass 12, it is convenient to observe the fermentation situation inside the tank body 1, by setting the annular ventilation pipe 13, it is convenient to pass the gas into the tank body 1, which can improve the contact between the fermentation substrate and oxygen, by setting the annular ventilation pipe 13 between the lower stirring blade 45 and the pressure plate 46, the gas sprayed from the annular ventilation pipe 13 can be dispersed by the lower stirring blade 45 and the pressure plate 46, which is more conducive to the uniform contact between the gas and the fermentation substrate, by setting the feed port 21, it is used to put the fermented material into the tank body 1, and by setting the annular spray pipe 22, it is used to supplement the catalyst and water.

[0065] Embodiment 4

[0066] like Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, the difference between this embodiment and the above embodiment is that the defoaming plate 52 includes a sliding disk 521, a cone head rod 522 and a floating block 523. The sliding disk 521 is slidably installed on the defoaming rotating rod 51, and the cone head rod 522 is fixedly installed in a ring array on the lower surface of the sliding disk 521. The floating block 523 is arranged between two adjacent rows of cone head rods 522, and the floating block 523 is fixedly connected to the lower surface of the sliding disk 521, and the thickness of the floating block 523 is less than the length of the cone head rod 522.

[0067] As can be seen from the above, by setting the sliding disk 521 and the defoaming rotating rod 51 in sliding connection, the defoaming plate 52 can only move up and down but cannot rotate relative to the defoaming rotating rod 51. Therefore, when the defoaming rotating rod 51 rotates, the defoaming plate 52 can rotate accordingly. By setting the floating block 523, since the floating block 523 is lighter and can float on the liquid surface, the defoaming plate 52 can always float above the liquid surface of the fermentation substrate. Therefore, when the defoaming rotating rod 51 rotates, the defoaming plate 52 floating on the liquid surface rotates accordingly. By fixing the cone head rod 522 at the bottom of the sliding disk 521, when the sliding disk 521 rotates, the cone head rod 522 will contact the approaching foam during rotation and crush and eliminate the foam.

[0068] Embodiment 5

[0069] like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Fig. 9 , Fig.11 and Fig.13 As shown, the difference between this embodiment and the above embodiment is that the driving mechanism 8 includes a driving bin 81, which is fixedly mounted on the inner top of the tank body 1, and the upper ends of the auger shaft 33, the upper rod 41 and the defoaming rotating rod 51 all penetrate the bottom wall of the driving bin 81 and are rotatably connected to the driving bin 81, and the auger shaft 33, the upper rod 41 and the defoaming rotating rod 51 are respectively fixedly mounted with a shaft driven gear 82, a driving gear 83 and a rotating rod driven gear 84, and the driving gear 83 is simultaneously connected with the shaft driven gear 82 and the rotating rod 54. The rod is driven by a gear 84, and the two sides of the interior of the driving bin 81 are rotatably installed with a shaft driving double-layer gear 85 and a rotating rod driving double-layer gear 86. The large diameter side of the shaft driving double-layer gear 85 is meshed with the driving gear 83, and the small diameter side of the shaft driving double-layer gear 85 is meshed with the shaft driven gear 82. The large diameter side of the rotating rod driving double-layer gear 86 is meshed with the driving gear 83, and the small diameter side of the rotating rod driving double-layer gear 86 is meshed with the rotating rod driven gear 84.

[0070] It can be seen from the above that since the driving gear 83 is simultaneously connected to the shaft driven gear 82 and the rotating rod driven gear 84, the auger shaft 33 and the defoaming rotating rod 51 both rotate with the upper rod 41. Due to the setting of the shaft driving double-layer gear 85 and the rotating rod driving double-layer gear 86, the angular velocity of the auger shaft 33 and the defoaming rotating rod 51 is smaller than the angular velocity of the upper rod 41, thereby preventing the auger shaft 33 and the defoaming rotating rod 51 from rotating too fast, resulting in severe heating inside the fermentation equipment due to excessive mechanical movement.

[0071] The upper end of the upper rod 41 passes through the top wall of the driving bin 81 and extends to the top of the driving bin 81 and is fixedly installed with a gear plate 87. The driving shaft of the driving motor 7 passes through the top wall of the tank cover 2 and extends to the interior of the tank cover 2 and is fixedly installed with a gear plate 88. The lower surface of the gear plate 88 is meshed with the upper surface of the gear plate 87.

[0072] Due to the arrangement of the toothed platform 87 and the toothed disc 88, when the tank cover 2 is removed, the toothed disc 88 is naturally separated from the toothed platform 87. When the tank cover 2 is removed, there is no need to remove the drive motor 7, so the tank cover 2 can be easily removed, thereby facilitating the cleaning of the inside of the tank body 1. When the tank cover 2 is installed, the toothed disc 88 is naturally contacted and engaged with the toothed platform 87, thereby realizing transmission.

[0075] By providing the jacket 14, a heat preservation effect can be achieved, thereby reducing the influence of the ambient temperature on the interior of the fermentation equipment.
