Abstract
Description
Technical Field
[0001] This utility model relates to the field of separation and screening technology, and in particular to a separation and screening device for a debittering enzyme used in the preparation of Majia pomelo juice. Background Technology
[0002] The debittering enzyme for Majia pomelo juice contains multiple enzyme systems, among which naringinase plays a major role. Naringinase is a complex enzyme composed of α-L-rhamnosidase and β-D-glucosidase. It is used as an important enzyme for hydrolyzing bitter substances in citrus juices. The hydrolysis process involves rhamnosidase first hydrolyzing naringin, a flavanone glycoside compound in citrus juice, into rhamnose and purine. The bitterness of purine is about 1 / 3 that of naringin, thus reducing the bitterness. Purine can then be further converted into non-bitter citrus glycosides and glucose under the continued action of β-D-glucosidase. Currently, naringinase is mainly produced by microbial fermentation, both domestically and internationally, and is mostly produced by fungi, such as Aspergillus niger, Penicillium, and Aspergillus oryzae. In the debittering enzyme production process, it is necessary to isolate and screen the strains carrying naringinase to remove impurities, dust, and debris. Existing separation and screening equipment mostly only allows for single-pass screening. After separation, impurities, dust, and smaller strains contained in the strains are mostly discharged and piled up together. If the smaller strains contained in the impurities are screened again, it becomes quite troublesome. Moreover, the dust contained in the strains is easily scattered during the screening process, affecting the staff's observation of the screening effect. Furthermore, the flying dust can easily be inhaled by the staff, causing harm. In addition, existing separation and screening equipment mostly requires the staff to manually pour the screened strains into the equipment. If there are many machines, manual feeding is time-consuming and labor-intensive. Therefore, those skilled in the art provide a separation and screening device for preparing debittering enzyme for Majia pomelo juice to solve the problems mentioned in the background art. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing separation and screening equipment, which mostly only allows for single-stage screening. Impurities, dust, and smaller strains contained in the strains tend to accumulate after separation, making further screening of the smaller strains difficult. Furthermore, the dust in the strains easily flies around during screening, affecting the worker's observation of the screening effect and potentially causing harm if inhaled. Additionally, existing separation and screening equipment often requires manual feeding of the strains, which is time-consuming and labor-intensive when the equipment is large. Therefore, this invention proposes a separation and screening device for preparing debittering enzymes for Majia pomelo juice.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a separation and screening device for preparing debittering enzyme for Majia pomelo juice, comprising a base, a set of electric telescopic rods symmetrically distributed in the middle of the upper surface of the base, a first positioning plate fixed to the top of the electric telescopic rods provided on the rear side of the top of the base, a second positioning plate fixed to the top of the electric telescopic rods provided on the front side of the top of the base, an inner screening cylinder engaged in the middle of the front side of the first positioning plate, a middle screening cylinder provided on the outer side of the inner screening cylinder, a first gear disk fixed to the rear side of the middle screening cylinder, an outer screening cylinder provided on the outer side of the middle screening cylinder, a second gear disk fixed to the front side of the outer surface of the outer screening cylinder, a third motor provided in the middle of the top of the first positioning plate, a double-headed gear rod fixed to the output end of the third motor, and the front and rear sides of the bottom end of the double-headed gear rod meshing with the middle of the top of the second gear disk and the first gear disk, respectively;
[0005] Through the above technical solution, during screening, the third motor is started, which drives the double-headed gear rod fixedly connected to the output end to rotate. The rotating double-headed gear rod drives the first gear disk and the second gear disk meshed at the bottom to rotate simultaneously. This causes the middle screening cylinder fixedly connected to the inner side of the first gear disk and the inner screening cylinder fixedly connected to the inner side of the middle screening cylinder to rotate synchronously. This causes the outer screening cylinder fixedly connected to the inner side of the second gear disk to rotate simultaneously. The rotating inner screening cylinder generates centrifugal force, which drives the impurities in the strains entering from the inner side to flow into the filter holes of the filter screen provided on the inner wall of the inner screening cylinder. The impurities and dust of the strains that enter the middle screening cylinder are smaller. When the middle screening cylinder is centrifugally rotated, the dust contained in it will be thrown by the centrifugal force and enter the outer screening cylinder through the holes opened on the inside of the middle screening cylinder. The outer screening cylinder blocks the flying dust and prevents the dust from splashing everywhere. This facilitates multiple screening and filtration of the strains that produce debittering enzyme, which helps to improve the filtration effect.
[0006] When the device is too high, the electric telescopic rod can be retracted to move the corresponding first and second positioning discs downward by a specified distance, thereby causing the inner screening cylinder, middle screening cylinder and outer screening cylinder provided between the first and second positioning discs to move downward by a specified distance simultaneously, thus completing the height adjustment.
[0007] Furthermore, a storage box is fixed to the rear side of the upper surface of the base, and an inclined platform is fixed to both the left and right ends of the inner side of the storage box. A first feeding pipe is fixed to the middle of the inner side of the storage box. A feeding screw is rotatably connected to the inner side of the first feeding pipe. A first motor is fixed to the middle of the top end of the first feeding pipe. The output end of the first motor is fixedly connected to the top of the feeding screw. A feed pipe is fixed to the top of the front side of the first feeding pipe. A second feeding pipe is fixed to the middle of the rear side of the first positioning plate.
[0008] With the above technical solution, during feeding, the first motor is started, which drives the feeding screw fixedly connected to the output end to rotate. At this time, the strains stored in the storage box will enter the feeding pipe under the guidance of the inclined table. The rotating feeding screw will push the contacting strains upward along the feeding pipe. When the upward-moving strains reach the feed inlet of the feed pipe, they will slide down into the feeding pipe along the inclined angle of the feed pipe. When the strains enter the feeding pipe, they will enter the inner screening cylinder along the column cavity opened in the middle of the feeding pipe and the first positioning plate, which facilitates automatic feeding into the screening equipment. The feeding process is more time-saving, labor-saving and convenient.
[0009] Furthermore, a first guide plate is provided in the middle of the lower front side of the outer screening cylinder, a first discharge hopper is fixed to the rear side of the first guide plate, and the bottom end of the first guide plate is fixedly connected to the upper surface of the base. A second guide plate is provided in the middle of the lower front side of the middle screening cylinder, a support baffle is fixed to the front side of the second guide plate, a feeding belt is provided above the front side of the support baffle, and a guide hopper is provided at one end of the feeding belt.
[0010] Through the above technical solution, when the dust inside the outer screening cylinder moves to the front of the inner side of the outer screening cylinder, it will fall onto the first guide plate under the action of gravity, slide along the inclined angle of the first guide plate into the first discharge hopper, and slide to one end along the first discharge hopper. When the impurities inside the middle screening cylinder are flipped and moved to the middle of the inner side of the middle screening cylinder, they will fall into the second guide plate under the action of gravity, and slide to the other end along the inclined angle of the second guide plate. When the strains carrying naringinase inside the inner screening cylinder are flipped and moved to the front of the inner screening cylinder, they will fall onto the feeding belt. The rotating feeding belt will push the strains to the designated position, fall into the guide hopper, and fall down into the conveyor device placed below, which facilitates the stratified discharge of the screened residue and facilitates better screening in the next step.
[0011] Furthermore, a first spiral feeding ring is fixed on the inner wall of both the inner and middle screening cylinders, and a second spiral feeding ring is fixed on the inner wall of the outer screening cylinder.
[0012] Through the above technical solution, when the inner screening cylinder and the middle screening cylinder rotate, the first spiral feeding ring inside them will turn over and guide the strains and impurities. At the same time, the first spiral feeding ring will slow down the speed at which the strains and impurities turn over and move to one end, thereby increasing the separation and screening time and improving the separation and screening effect. When the outer screening cylinder rotates, the second spiral feeding ring inside it will turn over and guide the dust.
[0013] Furthermore, a positioning baffle is provided on the front side of the feeding belt; a second motor is provided at one end of the upper front side of the positioning baffle, and a push shaft is provided at both the left and right ends of the inner side of the feeding belt; the output end of the second motor is fixedly connected to the push shaft at one end of the inner side of the feeding belt.
[0014] With the above technical solution, during material discharge, the second motor drives the push shaft connected to the output end to rotate, and the rotating push shaft will drive the outer meshing feeding belt to rotate.
[0015] Furthermore, six fixing rods are equidistantly fixed on the front surface of the second positioning disk, and a limiting disk is fixed to the front side of the fixing rods. The front side of the middle screening cylinder is rotatably connected to the middle part of the limiting disk.
[0016] Through the above technical solution, when the middle screening cylinder rotates, the limiting plate restricts the rotation trajectory of the middle screening cylinder, and the second positioning plate positions the outer screening cylinder.
[0017] This invention has the following advantages: it facilitates multiple centrifugal screening and separation, which helps to improve the screening and separation effect; it facilitates automatic feeding into the screening equipment, which is time-saving, labor-saving and convenient; and it facilitates the stratified discharge of the screened residue, which facilitates better subsequent screening.
[0018] 1. In this utility model, during screening, the third motor is started, which drives the double-headed gear rod at the output end to rotate. This causes the first gear disk and the second gear disk meshing at the bottom of the double-headed gear rod to rotate simultaneously. This causes the middle screening cylinder fixed inside the first gear disk and the inner screening cylinder fixed inside the middle screening cylinder to rotate synchronously. This causes the outer screening cylinder fixed inside the second gear disk to rotate simultaneously. The rotating inner screening cylinder generates centrifugal force, which drives the impurities in the strains entering from the inner side to flow into the filter holes of the filter screen provided on the inner wall of the inner screening cylinder. The impurities and dust of strains that enter the middle screening cylinder are smaller. When the middle screening cylinder is centrifugally rotated, the dust contained in it will be thrown by the centrifugal force and enter the outer screening cylinder through the holes opened on the inside of the middle screening cylinder. This facilitates multiple centrifugal screening and separation, which helps to improve the screening and separation effect. In this invention, during feeding, the first motor drives the feeding screw fixedly connected to the output end to rotate. At this time, the strains stored in the storage box will enter the feeding pipe under the guidance of the inclined angle of the inclined table. The rotating feeding screw will push the contacting strains upward along the feeding pipe. When the upward-moving strains reach the feed inlet of the feed pipe, they will slide down into the feeding pipe along the inclined angle of the feed pipe. When the strains enter the feeding pipe, they will enter the inner screening cylinder along the column cavity opened in the middle of the feeding pipe and the first positioning plate, which facilitates automatic feeding into the screening equipment. The feeding process is more time-saving, labor-saving and convenient. 3. In this utility model, during discharge, the dust inside the outer screening cylinder, when moving to the front of the outer screening cylinder, will fall onto the first guide plate under the action of gravity, slide along the inclined angle of the first guide plate into the first discharge hopper, and slide to one end along the first discharge hopper. The impurities inside the middle screening cylinder, when flipped and moved to the middle of the middle screening cylinder, will fall into the second guide plate under the action of gravity, and slide to the other end along the inclined angle of the second guide plate. The strains carrying naringinase inside the inner screening cylinder, when flipped and moved to the front of the inner screening cylinder, will fall onto the feeding belt. The rotating feeding belt will push the strains to the designated position, fall into the guide hopper, and fall down into the conveyor device placed below. This facilitates the stratified discharge of the screened residue, facilitates better screening of the screened impurities for the next step, and helps reduce material waste.

A limiting disk 14 is fixed on the front side of the fixing rods 24. The front side of the middle screening cylinder 26 is rotatably connected to the middle of the limiting disk 14.
[0026] Preferably: a storage box 2 is fixed to the rear side of the upper surface of the base 1, and an inclined platform 25 is fixed to both the left and right ends of the inner side of the storage box 2. A first feeding pipe 3 is fixed to the middle of the inner side of the storage box 2. A feeding screw rod 4 is rotatably connected to the inner side of the first feeding pipe 3. A first motor 5 is fixed to the middle of the top end of the first feeding pipe 3. The output end of the first motor 5 is fixedly connected to the top of the feeding screw rod 4. A feed pipe 6 is fixed to the top of the front side of the first feeding pipe 3. A second feeding pipe 22 is fixed to the middle of the rear side of the first positioning plate 7.
[0027] Preferably: A first guide plate 17 is provided in the middle of the lower front side of the outer screening cylinder 9, and a first discharge hopper 16 is fixed to the rear side of the first guide plate 17. The bottom end of the first guide plate 17 is fixedly connected to the upper surface of the base 1. A second guide plate 18 is provided in the middle of the lower front side of the middle screening cylinder 26. A support baffle is fixed to the front side of the second guide plate 18. A feeding belt 19 is provided above the front side of the support baffle. A guide hopper 20 is provided at one end of the feeding belt 19. A positioning baffle is provided at the front side of the feeding belt 19. A second motor 21 is provided at one end above the front side of the positioning baffle. A push shaft is provided at both the left and right ends of the inner side of the feeding belt 19. The output end of the second motor 21 is fixedly connected to the push shaft at one end of the inner side of the feeding belt 19.
[0028] Working principle: The first motor 5 drives the feeding screw 4, which is fixedly connected to the output end, to rotate. At this time, the strains stored in the storage box 2 will enter the first feeding pipe 3 under the guidance of the inclined table 25. The rotating feeding screw 4 will push the contacting strains upward along the first feeding pipe 3. When the upward-moving strains reach the feed inlet of the feed pipe 6, they will slide down into the second feeding pipe 22 along the inclined angle of the feed pipe 6. When the strains enter the second feeding pipe 22, they will enter the inner screening cylinder 15 through the column cavity opened in the middle of the second feeding pipe 22 and the first positioning plate 7. The third motor 23 drives the double-headed gear rod 12, which is fixedly connected to the output end, to rotate. The rotating double-headed gear rod... Rod 12 drives the first gear disk 8 and the second gear disk 13, which are meshed at their bottom ends, to rotate simultaneously. This causes the middle screening cylinder 26, which is fixedly connected to the inner side of the first gear disk 8, and the inner screening cylinder 15, which is fixedly connected to the inner side of the middle screening cylinder 26, to rotate synchronously. This causes the outer screening cylinder 9, which is fixedly connected to the inner side of the second gear disk 13, to rotate simultaneously. The rotating inner screening cylinder 15 generates centrifugal force, which drives the impurities in the strains entering from the inside to flow into the filter holes of the filter screen provided on the inner wall of the inner screening cylinder 15. At the same time, the first spiral feeding ring 27 provided inside it will turn the strains over and guide them. The first spiral feeding ring 27 slows down the speed at which the strains turn over to one end, thereby increasing the separation and screening time. Impurities enter the middle screening cylinder through the filter holes. The first spiral feeding ring 27 inside the middle screening cylinder 26 flips and guides impurities, causing impurities, dust, and smaller bacteria entering the middle screening cylinder 26 to slowly flip to one end. When the middle screening cylinder 26 rotates centrifugally, the dust it contains is propelled by centrifugal force through the holes in the middle screening cylinder 26 into the outer screening cylinder 9. The outer screening cylinder 9 blocks the flying dust, while the second spiral feeding ring 28 flips and guides the dust. When the dust inside the outer screening cylinder 9 moves to the front of the outer screening cylinder 9, it falls onto the first guide plate 17 under gravity and slides along the inclined angle of the first guide plate 17 into the first discharge hopper 16. The first hopper 16 slides to one end. When the impurities inside the middle screening cylinder 26 are flipped and moved to the middle of the inner side of the middle screening cylinder 26, they fall into the second guide plate 18 under the action of gravity and slide to the other end along the inclined angle of the second guide plate 18. When the strains carrying naringinase inside the inner screening cylinder 15 are flipped and moved to the front side of the inner screening cylinder 15, they fall onto the feeding belt 19. The second motor 21 drives the push shaft connected to the output end to rotate. The rotating push shaft will drive the outer meshing feeding belt 19 to rotate. The rotating feeding belt 19 will push the strains to the designated position, fall into the guide hopper 20, and fall down into the transport device placed below.Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
