Description
Technical Field
[0001] The present application relates to the technical field of red yeast rice slice production, and specifically discloses a drying device for red yeast rice slice production. Background Art
[0002] Red yeast rice slices are made from the traditional Chinese medicinal ingredient red yeast rice (made from glutinous rice fermented with Monascus purpureus). They are processed through a series of processes, including cleaning, slicing, and drying. After fermentation and cutting, red yeast rice slices typically have a high moisture content (approximately 10%-15%). If not dried promptly, they are prone to mold growth and mildew. Drying is necessary to reduce the moisture content of the slices, ensuring the stability of their active ingredients, microbiological safety, and long-term storage.
[0003] The drying process is not easy, and the red yeast rice slices are often not easy to be dried.
[0004] Therefore, in view of this, the present invention provides a drying device for the production of red yeast rice slices to solve the above problems. Summary of the Invention
[0005] The purpose of the present invention is to solve the problem that in the traditional red yeast rice slice drying process, part of the red yeast rice slices are in contact with the placement rack, and there are some dead corners that cannot be reached by hot air, resulting in incomplete drying of the red yeast rice slices.
[0006] In order to achieve the above-mentioned object, the basic solution of the present invention provides a drying device for producing red yeast rice slices, comprising: The drying box has a door on one side, a hot air pipe connected to the bottom of the drying box, and an exhaust port on the top of the drying box; The drying rack provided in the drying box includes a plurality of connecting racks uniformly arranged vertically in the drying box, wherein the connecting racks are rotatably connected to a plurality of placement bars, the placement bars are provided with placement grooves, the thickness of the placement grooves is between the single thickness and the double thickness of the red yeast rice slices, and the side walls and the bottom of the placement bars are provided with a plurality of air holes connected to the placement grooves; A driving mechanism for driving each placement bar to move back and forth.
[0007] The principles and effects of this basic solution are: Compared with the prior art, the present invention uses a driving mechanism to drive each placement bar to move back and forth while drying the red yeast rice slices in the placement trough, so that the two side surfaces of the red yeast rice slices are in contact with the two inner walls of the placement trough in an alternating manner, thereby promoting the uniformity of heating on the two sides of the dried slices and preventing the red yeast rice slices from being in continuous contact with the placement trough to avoid the occurrence of drying dead corners. This effectively solves the problem of incomplete drying of the red yeast rice slices in the traditional drying process, in which part of the red yeast rice slices are in contact with the placement rack, and there are some dead corners that cannot be reached by hot air.
[0008] Furthermore, air guide gaps are formed between the placement bars, and the placement bars and the air guide gaps are vertically staggered in the drying box. The placement bars are vertically staggered so that the hot air forms an S-shaped flow path in the drying box, thereby promoting contact between the hot air and the red yeast rice slices, thereby improving the drying effect of the red yeast rice slices.
[0009] Furthermore, the driving mechanism includes: Power parts; A slide plate which is laterally slidably connected to the drying box and driven by a power member; a rack provided on the slide; A gear located at the end of the placement bar and meshing with the rack.
[0010] The power part is used to drive the slide to move back and forth, thereby driving the rack to move back and forth, so that the gear and the placement bar are moved back and forth, which causes the two side surfaces of the red yeast rice slices to contact the two inner walls of the placement groove alternately, promoting uniform heating on both sides of the dried slices.
[0011] Furthermore, the racks include an upper rack located at the top of the slide and a lower rack located at the bottom of the slide, and the racks on the vertically adjacent placement bars mesh with the upper rack and the lower rack, respectively. This arrangement allows the vertically adjacent placement bars to be reciprocated in opposite directions, so that during the movement of the placement bars, the air guide gaps are staggered vertically, horizontally, and diagonally, thereby preventing the hot air from flowing directly vertically, horizontally, or diagonally, thereby increasing the hot air flow path, that is, promoting contact between the hot air and the red yeast rice slices, and thereby improving the drying effect of the red yeast rice slices.
[0012] Furthermore, the driving mechanism further includes a cam driven to rotate by the plurality of power members, a push rod provided at one end of each slide plate and capable of being compressed by the cam, and a first spring provided at the other end of each slide plate. The cam compresses the push rod and slide plate, and the elastic potential energy of the first spring is used to drive the slide plate to slide back and forth.
[0013] Furthermore, the cam's offset increases vertically, and the drive mechanism also includes a linear drive member that drives the cam's vertical motion. The output shaft of the power member is spline-connected to the camshaft of the cam. The drive member drives the camshaft and cam to move, so that different positions of the cam contact the push rod, which in turn drives the push rod and the placement block to move at different amplitudes, facilitating the placement, drying, and removal of the red yeast rice slices from the placement slot.
[0014] Furthermore, the drying box is provided with a feed bin at the top, a plurality of longitudinal guide plates at the bottom thereof, longitudinal guide gaps being formed between the longitudinal guide plates, and a plurality of transverse guide plates at the bottom thereof, transverse guide gaps being formed between the transverse guide plates. This improves the uniformity of the distribution of the red yeast rice slices within the drying box, allowing more red yeast rice slices to fall into each placement slot.
[0015] Furthermore, a collecting box is provided on one side of the drying box near the door thereof, which is slidably connected to the bottom of the drying box, so as to collect the red yeast rice slices that have not fallen into each placement slot and the dried red yeast rice slices.
[0016] Based on the same inventive concept, the present invention discloses a drying method for the production of red yeast rice slices, comprising using the above-mentioned drying device to perform a drying process on the sliced red yeast rice slices.
[0017] Further, the steps of using the above-mentioned drying device to dry the sliced red yeast rice slices are as follows: Step S1, placing each red yeast rice slice into each placement slot in a single arrangement; Step S2, hot air is introduced into the drying box to dry the red yeast rice slices in the placement grooves, and at the same time, the driving mechanism drives each placement bar to move back and forth so that the two sides of the red yeast rice slices are staggered and contact the two inner walls of the placement grooves, thereby promoting uniform heating of the two sides of the dried slices; Step S3, taking out the dried red yeast rice slices.
[0018] This method effectively solves the problem that in the traditional red yeast rice slice drying process, part of the red yeast rice slices are in contact with the placement rack, and there are some dead corners that cannot be reached by hot air, resulting in incomplete drying of the red yeast rice slices.

DETAILED DESCRIPTION
[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0022] The figure marks in the drawings of the specification include: drying box 1, feeding bin 2, box door 3, collecting box 4, transmission box 5, motor 6, cylinder 7, first placement bar 8, second placement bar 9, guide sleeve 10, upper gear 11, lower gear 12, slide plate 13, baffle 14, first spring 15, output shaft 16, camshaft 17, cam 18, base circle end 1801, connecting hole 1802, keyway 1803, roller end 1804, red yeast rice slices 19, first connecting frame 20, sleeve 21, lever 22, protrusion 23, connecting shaft 24, and second spring 25.
[0023] A drying device for producing red yeast rice slices, for example Figure 1As shown: it includes a drying box 1, a drying rack arranged in the drying box 1 and a driving mechanism, wherein the front side of the drying box 1 is provided with a box door 3 and a collecting box 4 slidingly connected to the bottom of the drying box 1, the rear side of the bottom of the drying box 1 is connected with a hot air duct, the top of the drying box 1 is provided with an exhaust port and a feed bin 2, the bottom of the feed bin 2 is provided with a plurality of longitudinal guide plates, longitudinal guide gaps are formed between the longitudinal guide plates, and a plurality of transverse guide plates are provided at the bottom of the longitudinal guide plates, transverse guide gaps are formed between the transverse guide plates; the gap widths of the longitudinal guide gaps and the transverse guide gaps increase from top to bottom, and extend evenly to the front and back sides and left and right sides of the drying box 1, thereby improving the uniformity of the distribution of the red yeast rice slices 19 in the drying box 1.
[0024] The drying rack includes a plurality of connecting racks uniformly arranged vertically in the drying box 1, wherein the connecting racks are arranged in groups, including a first connecting rack and a second connecting rack adjacent to each other vertically, such as Figure 2 As shown, a plurality of first placement bars 8 and second placement bars 9 are rotatably connected to the first connecting frame 20 and the second connecting frame respectively. The first placement bars 8 and the second placement bars 9 are provided with placement grooves. The side walls and bottoms of the first placement bars 8 and the second placement bars 9 are provided with a plurality of air holes connected to the placement grooves. In this embodiment, the thickness of the placement grooves is between the single thickness and double thickness of the red yeast rice slices 19, preferably 1.5 times the thickness of the red yeast rice slices 19. An air guide gap is formed between the placement bars, and the air guide gap is the same as the thickness of the placement grooves.
[0025] like Figure 3 As shown, the driving mechanism includes a power member, a cam 18 driven to rotate by the power member, a linear driving member that drives the cam 18 to move vertically, and a plurality of slides 13 that are laterally slidably connected to the drying box 1, wherein one end of the slide 13 is provided with a push rod that can be squeezed by the cam 18, one end of the slide 13 is provided with a guide shaft, and the side wall of the drying box 1 is provided with a guide sleeve 10, one end of the guide shaft is slidably connected to the guide sleeve 10, and the other end of the guide shaft is provided with a baffle 14, and a first spring 15 is provided between the baffle 14 and the guide sleeve 10; the top and bottom of the slide 13 are respectively provided with an upper rack and a lower rack, and the side walls of the first placement bar 8 and the second placement bar 9 are respectively provided with an upper gear 11 and a lower gear 12 that mesh with the upper rack and the lower rack.
[0026] like Figure 3 and Figure 4As shown, the base circular end 1801 of cam 18 lies in the same vertical direction, the roller end 1804 of cam 18 gradually increases in thickness, and a connecting hole 1802 and a keyway 1803 are provided within cam 18 to mate with camshaft 17. The offset of cam 18 increases vertically. The linear drive element is a cylinder 7, the piston rod of cylinder 7 and the camshaft 17 of cam 18 are connected via a connecting seat. The power element is a motor 6, and the output shaft 16 of motor 6 is spline-connected to camshaft 17. A transmission case 5 is provided on the outside of drying box 1 to protect cam 18, and a protective box is provided inside drying box 1 to protect the upper and lower racks, upper gear 11, and lower gear 12.
[0027] The offset of the cam 18 has at least three different gears, which are used to place the red yeast rice slices 19 into the placement slot, dry them in the placement slot, and pour them out of the placement slot. The position of the camshaft 17 is adjusted by the cylinder 7, so that different positions of the cam 18 contact the push rod, which in turn pushes the push rod to different degrees of rotation, driving the placement block to move by different amplitudes. This structure is not only easy to control, but also does not require the reciprocating rotation of the motor 6 to increase energy consumption. Correspondingly, a control box and controller are set outside the box to control the motor 6, cylinder 7, and the hot air blower on the hot air pipe.
[0028] like Figure 5 As shown, when the placement bar is moved, the side surfaces of the red yeast rice slices 19 are staggered to contact the two inner walls of the placement groove, which promotes the uniformity of heating on both sides of the dried slices and prevents the red yeast rice slices 19 from being in continuous contact with the placement groove to avoid the occurrence of drying dead corners.
[0029] like Figure 6 As shown, the connecting frame is also provided with a screening mechanism that allows each first placement bar 8 and second placement bar 9 to move back and forth. Taking the first placement bar 8 as an example, the gear shaft of the upper gear 11 of the first placement bar 8 is rotatably and slidably connected to the first connecting frame 20, and a sleeve 21 is provided through the first connecting frame 20, and a shift rod 22 is provided on the sleeve. The first connecting frame 20 is provided with a plurality of protrusions 23 that can squeeze the shift rod. A connecting shaft 24 is provided in the protective box, and the sleeve 21 is slidably connected to the connecting shaft 24, and a second spring 25 is provided on the connecting shaft to reset the sleeve 24 and the first placement bar 8. In the process of the first placement bar 8 being driven back and forth by the upper gear 11, the shift rod 22 cooperates with the protrusion 23, and the elastic potential energy of the second spring 25, so that the first placement bar 8 performs reciprocating screening back and forth, thereby making the red yeast rice slices 19 more evenly distributed in the placement groove. Of course, the height of the protrusion 23 is less than the tooth width of the upper gear 11 and the upper rack to prevent the first placement bar 8 from causing the upper gear 11 to disengage from the upper rack.
[0030] Based on the same inventive concept, the present invention discloses a drying method for producing red yeast rice slices, comprising using the above-mentioned drying device to dry the sliced red yeast rice slices, and the steps are as follows: Step S1, placing each red yeast rice slice in a single-piece arrangement into each placement groove, specifically, pouring the red yeast rice slices from the feed bin 2 into the drying box 1, and starting the driving mechanism at the same time, the cylinder 7 operates so that the end of the cam 18 with a smaller offset contacts the push rod, thereby driving the placement bar to perform a low-amplitude toggle, and the toggle amplitude is 10-30°. The red yeast rice slices pass through the longitudinal guide gap and the transverse guide gap in sequence and fall into the placement groove. After the red yeast rice slices are present in the placement groove, the subsequent red yeast rice slices either fall into the placement groove and are arranged in a row, or fall into the placement groove below from the air guide gap, until most of the placement grooves are arranged with red yeast rice slices, and the red yeast rice slices that fall to the bottom of the drying box 1 are collected and taken out through the collecting box 4; Step S2, hot air is introduced into the drying box 1 through the hot air blower and the hot air pipe to dry the red yeast rice slices in the placement groove, and at the same time, the end of the cam 18 with a more moderate offset contacts the push rod, thereby driving the placement bar to perform a medium amplitude toggle, and the toggle amplitude is 30-60 degrees so that the two side surfaces of the red yeast rice slices are staggered and contact the two inner walls of the placement groove, thereby promoting the uniformity of heating on the two sides of the dried slices, and in this process, when the placement bar is toggled, the air guide gaps are staggered with each other in the vertical, horizontal and oblique directions to avoid direct vertical, horizontal or oblique flow of hot air, thereby increasing the circulation path of the hot air, that is, promoting the contact between the hot air and the red yeast rice slices, thereby improving the drying effect of the red yeast rice slices; Step S3, after the drying is completed, the cylinder operates so that the end of the cam 18 with a larger offset contacts the push rod, thereby driving the placement bar to move significantly, the movement amplitude is greater than 180°, so that each placement frame opens downward, pours out the red yeast rice slices inside, and collects and takes them out through the collection box 4.
[0031] Obviously, the present invention uses a driving mechanism to drive each placement bar to move back and forth while drying the red yeast rice slices in the placement trough, so that the two side surfaces of the red yeast rice slices are in contact with the two inner walls of the placement trough in an alternating manner, thereby promoting the uniformity of heating on the two sides of the dried slices, and at the same time preventing the red yeast rice slices from being in continuous contact with the placement trough, so as to avoid the occurrence of drying dead corners, and effectively solves the problem of incomplete drying of the red yeast rice slices in the traditional drying process, in which part of the red yeast rice slices are in contact with the placement rack, and there are some dead corners that cannot be reached by hot air.
[0032] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any indirect modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
