Description

Technical Field

[0001] This invention relates to an industrial juicer for deep processing of Napier grass, which is mainly used for batch juicing of Napier grass and can effectively and significantly improve juicing efficiency. Background Technology

[0002] The juice of Napier grass contains active ingredients that help inhibit bacterial growth and reduce skin inflammation, thus effectively relieving skin sores, eczema itching, and even redness, swelling, heat, and pain caused by mosquito bites due to damp heat. Currently, the juicing and processing of Napier grass mainly uses conventional roller press juicing equipment.

[0003] The existing roller press juicing equipment has the following main defects in the process of juicing Napier grass: 1) Due to the long length of Napier grass, directly feeding it into the roller press juicing equipment can easily cause the Napier grass to entangle in the equipment, resulting in frequent shutdowns for cleaning the residue. To solve this problem, some manufacturers pre-cut the Napier grass before feeding it into the roller press for juicing. However, the cut Napier grass is difficult to feed, which is very troublesome; 2) The juice content of Napier grass is relatively limited. In order to ensure the juicing rate, the raw material often needs to be roller pressed multiple times, making it difficult to effectively improve the juicing rate.

[0004] Therefore, the research objective of this invention is to design an industrial juicer for deep processing of Napier grass that can effectively facilitate the feeding and juicing process and significantly improve the juicing effect and efficiency. Summary of the Invention

[0006] The technical solution of this invention is: An industrial juicer for deep processing of foxtail grass includes: The frame is equipped with a feed hopper, a pretreatment zone and a slag-liquid separation zone arranged at different heights. A roller feeding mechanism is used to roll and convey the material in the feed hopper to the pretreatment area. The material cutting and pressing mechanism includes a cutting plate vertically arranged in the pretreatment area, a material cutting blade horizontally movable on the outer side of the cutting plate, and a material pressing roller tangentially arranged to the bottom side of the cutting blade for crushing and pressing the material. An ultrasonic vibrator is installed on the crushing roller. A heat softening feeding mechanism is connected between the pretreatment zone and the slag-liquid separation zone. It is used to heat and soften the material after roller pressing and to transport it to the centrifugal separation zone. A juice-liquid separation device includes a primary filter cylinder spaced apart within the residue-liquid separation zone and a secondary filter cylinder coaxially disposed inside it. The bottom of the secondary filter cylinder extends to the bottom of the primary filter cylinder, and the top of the secondary filter cylinder is sealed and fixedly connected with a corresponding end cover plate. The end cover plate has several residue outlets, and a material lifting auger for squeezing and conveying the material in the primary filter cylinder through the secondary filter cylinder is rotatably disposed in the middle of the end cover plate. Juice collection mechanism, used to discharge and collect the juice separated by the primary and secondary filter cartridges; The slag collection trough is used to collect the slag discharged from the slag outlet and discharge it to the outside of the frame.

[0007] The industrial juicer also includes a discharge pressure control mechanism, which includes a fixed plate disposed on the upper side of the end cover plate. A corresponding connecting plate is installed on the bottom side of the fixed plate via a corresponding elastic element. The connecting plate is fixedly connected downward to a plurality of baffle rods for sealing the slag outlet of the end cover plate. The bottom ends of the baffle rods are respectively arranged in an outward inclined shape.

[0008] The bottom side of the fixing plate is provided with a number of corresponding guide sleeves, and the top of the connecting plate is fixed with a number of guide shafts that are adapted to the guide sleeves. The guide shafts are movably inserted into the guide sleeves and fixed to the guide sleeves through the elastic element.

[0009] A set of electromagnets with corresponding positions are fixed to one side of the fixed plate and the connecting plate, wherein one electromagnet is a fixed electromagnet and the other electromagnet is an adjustable electromagnet.

[0010] The roller pressing feeding mechanism includes an inclined guide plate installed at an angle on the lower side of the feed hopper. A corresponding pressing roller is provided on the upper side of the middle part of the inclined guide plate. The pressing roller is driven to rotate by a corresponding pressing drive motor.

[0011] The frame is provided with a blade mounting plate corresponding to the position of the cutting blade. The blade mounting plate is provided with corresponding blade mounting holes. The cutting blade is horizontally movable and inserted into the blade mounting holes of the blade mounting plate, and is driven back and forth by a corresponding cutting drive mechanism.

[0012] The cutting drive mechanism includes a drive shaft mounted on the frame. A set of drive wheels are installed at intervals in the middle of the drive shaft. The cutting blade is eccentrically hinged to the periphery of the set of drive wheels via a corresponding tie rod. The drive shaft is driven by a cutting drive motor.

[0013] A drive shaft corresponding to the position of the lifting auger is rotatably mounted on the frame. The drive shaft and the crushing roller are respectively connected to the drive shaft by belt drive or chain drive. The lifting auger is connected to the drive shaft by gear drive.

[0014] The crushing roller is hollow, and the ultrasonic vibrator is fixedly installed in the hollow part of the crushing roller and connected to an external electrical controller through a corresponding electrical connection rotary joint.

[0015] The upper part and both sides of the cutting plate are respectively connected to the frame through corresponding buffer rubber sheets. The heat softening guide mechanism includes a heating guide plate inclinedly arranged on the lower side of the cutting plate. A corresponding electric heater is fixed to the bottom side of the heating guide plate. The upper part of the heating guide plate is fixed to the cutting plate. The two sides of the heating guide plate are respectively connected to the frame through corresponding heat-resistant rubber sheets. A set of guide plates for guiding the material into the primary filter cylinder is provided on the lower side of the heating guide plate.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1) The frame of this invention is equipped with a feeding hopper, a pretreatment zone, and a slag-liquid separation zone arranged at different heights. The material entering the feeding hopper is pre-pressed by a roller-feeding mechanism and conveyed to the pretreatment zone to ensure smooth material transport and initial crushing. Then, a vertically arranged cutting plate longitudinally transports the initially crushed material, and during this longitudinal transport, horizontally arranged cutting blades cut it to a fixed length. The cut material falls between the crushing roller and the cutting plate, and as the crushing roller rotates, it is squeezed downwards between the crushing roller and the cutting plate. After being squeezed by high-frequency vibration, the material effectively achieves sufficient slag-liquid separation and thoroughly crushes the slag. Subsequently, the slag and liquid pass through a heat-softening guiding mechanism. The material is centrally guided to the residue-liquid separation zone. During this process, the crushed material is directly heated, passing through a heating environment of 60-80℃. This partially hydrolyzes the pectin and hemicellulose in the cell walls of the material, further reducing its structural rigidity, promoting cell wall rupture, and releasing intracellular juice and active ingredients to increase the juicing rate. The crushed and heated material then enters a primary filter cylinder for primary residue-juicing separation. After primary separation, the material is lifted by a screw conveyor and finally discharged through the slag outlet of the end cover. This extrusion process effectively performs secondary residue-juicing separation. The separated juice is collected and discharged by a juice collection mechanism, while the residue is collected and discharged through a slag collection trough. This effectively facilitates the smooth progress of the feeding and juicing process and significantly improves the juicing effect and efficiency.

[0017] 2) This invention also includes a discharge pressure control mechanism, which comprises a fixed plate disposed on the upper side of the end cover plate. A connecting plate is ellipsably mounted on the bottom side of the fixed plate via an elastic element. Several baffle rods for sealing the slag outlet of the end cover plate are fixedly connected downwards to the connecting plate. Under the action of the discharge pressure control mechanism, when the material after secondary slag-juice separation is discharged through the slag outlet of the end cover plate, it needs to be pushed against the baffle rods before being discharged, so as to effectively improve the secondary slag-juice separation effect of the material under the condition of elastic compression.

[0018] 3) Based on the outward-facing inclined planes at the bottom ends of the baffle rods, this invention further fixes a set of electromagnets to opposite sides of the fixed plate and the connecting plate. One electromagnet is a fixed-pole electromagnet, and the other is an adjustable-pole electromagnet. During the secondary slag-juice separation process, the set of electromagnets is energized periodically. During this process, the poles of the adjustable-pole electromagnet are adjusted to be in the same direction as the fixed-pole electromagnet, causing a repulsive force between them. This drives the connecting plate and the baffle rods to descend intermittently, intermittently cutting off the discharged slag and thus helping to improve the smoothness of slag discharge.

[0019] When the equipment needs to be cleaned, a set of electromagnets is energized, and the magnetic poles of the adjustable electromagnets are adjusted to be opposite to those of the fixed electromagnets, so as to drive the connecting plate, i.e., the material blocking rod, away from the slag outlet of the end cover plate. At this time, simply pouring external water into the slag outlet of the end cover plate can effectively clean the juice separation device of the present invention.

[0020] 4) The cutting drive mechanism of the present invention includes a drive shaft mounted on a frame. A set of drive wheels are spaced apart at the center of the drive shaft. The cutting blade is eccentrically hinged to the periphery of the drive wheel via a corresponding tie rod. A transmission shaft corresponding to the position of the lifting auger is rotatably mounted on the frame. The transmission shaft and the crushing roller are respectively connected to the drive shaft of the cutting drive mechanism via belt drive or chain drive. The lifting auger is then connected to the transmission shaft via gear drive. In this way, the cutting blade, crushing roller, and lifting auger can be synchronously driven by a single power source, thereby reducing the manufacturing and subsequent operation and maintenance costs of the equipment.

[0021] 5) The upper part and both sides of the cutting plate of the present invention are connected to the frame via buffer rubber sheets. The heat softening guiding mechanism includes a heating guiding plate inclinedly disposed on the lower side of the cutting plate. A corresponding electric heater is fixedly connected to the bottom side of the heating guiding plate, and the upper part of the heating guiding plate is fixedly connected to the cutting plate. The two sides of the heating guiding plate are respectively connected to the frame via corresponding heat-resistant rubber sheets. In this way, it can not only effectively adapt to the transfer of ultrasonic vibration of the pressing roller to the cutting plate to improve the crushing effect of the material, but also fully transmit ultrasonic vibration to the heating guiding plate to ensure the transmission stability of the crushed material on the heating guiding plate, and ensure that the crushed material can pass through the heating guiding plate more evenly and loosely, thereby ensuring the heat treatment effect of the crushed material.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] refer to Figure 1-6 An industrial juicer for deep processing of foxtail grass, comprising: The frame 1 is provided with a feed hopper 101, a pretreatment zone 102 and a slag-liquid separation zone 103 arranged at different heights. Roller feeding mechanism 2 is used to roll and convey the material in the feed hopper 101 to the pretreatment area 102; The cutting roller pressing mechanism 3 includes a cutting plate 301 vertically arranged in the pretreatment area 102. A material cutting blade 302 is horizontally movably installed on the outer side of the cutting plate 301. A material crushing roller 303 tangentially arranged with the cutting plate 301 is rotatably installed on the bottom side of the cutting blade 302. An ultrasonic vibrator 4 is installed on the crushing roller 303. The heat softening feeding mechanism 5 is connected between the pretreatment zone 102 and the residue-liquid separation zone 103, and is used to heat and soften the material after roller pressing and transport it to the residue-liquid separation zone 103. Juice separation device 6 includes a primary filter cylinder 601 spaced apart within the residue-liquid separation zone 103 and a secondary filter cylinder 602 coaxially disposed inside it. The bottom of the secondary filter cylinder 602 extends to the bottom of the primary filter cylinder 601. The top of the secondary filter cylinder 602 is sealed and fixedly connected with a corresponding end cover plate 8. The end cover plate 8 has a plurality of residue outlets 801, and a material lifting auger 9 is rotatably disposed in the middle of the end cover plate 8 for squeezing and conveying the material in the primary filter cylinder 601 through the secondary filter cylinder 602. Juice collection mechanism 7 is used to discharge and collect the juice separated by the primary filter cartridge 601 and the secondary filter cartridge 602. In this embodiment, the juice collection mechanism 7 includes a juice collection cylinder 701 sandwiched around the secondary filter cartridge 602. The juice collection cylinder 701 is connected to the gap between the primary filter cartridge 601 and the residue-liquid separation zone 103 through a corresponding conduit 702. The bottom of the gap between the primary filter cartridge 601 and the residue-liquid separation zone 103 is connected to a corresponding juice collection pipe 703. The slag collection trough 10 is used to collect the slag material discharged from the slag outlet 801 and discharge it to the outside of the frame 1.

[0031] The frame 1 of this invention is equipped with a feed hopper 101, a pretreatment zone 102, and a slag-liquid separation zone 103 arranged at different heights. The material entering the feed hopper 101 is pre-pressed by a roller-feeding mechanism 2 and conveyed to the pretreatment zone 102 to ensure smooth material transport and initial crushing. Then, the initially crushed material is longitudinally conveyed by a vertically arranged cutting plate 301, and during this longitudinal transport, it is cut to a fixed length by a horizontally arranged cutting blade 302. The cut material falls between the crushing roller 303 and the cutting plate 301, and is pressed downwards between the crushing roller 303 and the cutting plate 301 as the crushing roller 303 rotates. The material undergoes high-frequency vibration and compression, effectively achieving sufficient slag-liquid separation and thoroughly crushing the slag. Subsequently, the slag... The juice is fed into the residue-liquid separation zone 103 via a heat-softening feeding mechanism 5. During this process, the crushed material is directly heated, passing through a 60-80°C heating environment. This hydrolyzes pectin and hemicellulose in the cell walls, further reducing the material's structural rigidity, promoting cell wall rupture, and releasing intracellular juice and active ingredients to increase the juicing rate. The crushed and heated material then enters the primary filter cylinder 601 for primary residue-juicing separation. After primary separation, the material is lifted by the screw conveyor 9 and discharged through the slag outlet 801 of the end cover plate 8. This extrusion process effectively performs secondary residue-juicing separation. The separated juice is collected by the juice collection mechanism 7, while the residue is collected and discharged through the slag collection trough 10. This facilitates smooth feeding and the overall juicing process, significantly improving the juicing effect and efficiency.

[0032] The industrial juicer also includes a discharge pressure control mechanism 11. The discharge pressure control mechanism 11 includes a fixed plate 1101 disposed on the upper side of the end cover plate 8. A corresponding connecting plate 1103 is ellipsably mounted on the bottom side of the fixed plate 1101 via a corresponding elastic element 1102. The connecting plate 1103 is fixedly connected downward to a plurality of baffle rods 1104 for closing the slag outlet 801 of the end cover plate 8. The bottom ends of the baffle rods 1104 are respectively arranged in an outward inclined shape.

[0033] Under the combined action of the fixed plate 1101, elastic element 1102, connecting plate 1103, and baffle rod 1104 of the discharge pressure control mechanism 11, when the material after secondary slag and juice separation is discharged through the slag outlet 801 of the end cover plate 8, the baffle rod 1104 needs to be pushed before it can be discharged, so as to effectively improve the secondary slag and juice separation effect of the material under the condition of elastic compression.

[0034] The bottom side of the fixing plate 1101 is provided with a number of corresponding guide sleeves 12. The top of the connecting plate 1103 is fixedly connected with a number of guide shafts 13 that are adapted to the guide sleeves 12. The guide shafts 13 are movably inserted into the guide sleeves 12 and fixed to the guide sleeves 12 through the elastic element 1102.

[0035] A set of corresponding electromagnets 14 are fixedly connected to the opposite side of the fixing plate 1101 and the connecting plate 1103, wherein one electromagnet 14 is a fixed-pole electromagnet and the other electromagnet 14 is an adjustable-pole electromagnet. In this embodiment, the bottom end of the primary filter cylinder 601 is connected to a drain pipe 23 with a drain valve 2301 installed.

[0036] In addition to the outward-facing inclined surfaces at the bottom ends of the baffle rods 1104, this invention further fixes a set of electromagnets 14 to opposite sides of the fixed plate 1101 and the connecting plate 1103. During the secondary slag-juice separation process, the set of electromagnets 14 is energized periodically. During this process, the magnetic poles of the adjustable electromagnets are adjusted to be in the same direction as the fixed electromagnets, causing a repulsive force between them. This drives the connecting plate 1103 and the baffle rods 1104 to descend intermittently, thereby intermittently cutting off the discharged slag and improving the smoothness of slag discharge.

[0037] When cleaning is required, a set of electromagnets 14 are energized, and the poles of the adjustable electromagnets are adjusted to be opposite to those of the fixed electromagnets. This drives the connecting plate 1103, i.e., the baffle rod 1104, away from the slag outlet 801 of the end cover plate 8. At this time, simply pouring external water through the slag outlet 801 of the end cover plate 8 is sufficient to effectively clean the juice separation device 6 of this invention. During the cleaning process, the drain valve 2301 is opened to discharge the cleaning water and corresponding dirt.

[0038] The roller pressing and feeding mechanism 2 includes an inclined guide plate 201 that is inclinedly installed on the lower side of the feed hopper 101. A corresponding pressing roller 202 is provided on the upper side of the middle part of the inclined guide plate 201. The pressing roller 202 is driven to rotate by a corresponding pressing drive motor 203.

[0039] The frame 1 is provided with a blade mounting plate 15 corresponding to the position of the cutting blade 302. The blade mounting plate 15 is provided with corresponding blade mounting holes. The cutting blade 302 is horizontally movable and inserted into the blade mounting holes of the blade mounting plate 15, and is driven back and forth by the corresponding cutting drive mechanism 16.

[0040] The cutting drive mechanism 16 includes a drive shaft 1601 mounted on the frame 1. A set of drive wheels 1602 are installed at intervals in the middle of the drive shaft 1601. The cutting blade 302 is eccentrically hinged to the periphery of the set of drive wheels 1602 via a corresponding tie rod 1603. The drive shaft 1601 is driven by a cutting drive motor 1604.

[0041] A drive shaft 17 corresponding to the position of the lifting auger 9 is rotatably mounted on the frame 1. The drive shaft 17 and the crushing roller 303 are respectively connected to the drive shaft 1601 by belt drive. The lifting auger 9 is connected to the drive shaft 17 by gear drive.

[0042] Through the specific configuration of the cutting drive mechanism 16 of the present invention, and the intervention of components such as the transmission shaft 17, the present invention can realize the synchronous drive of the cutting blade 302, the crushing roller 303, and the lifting auger 9 with the intervention of a power source, so as to effectively reduce the manufacturing cost of the equipment and the subsequent operation and maintenance cost.

[0043] The material crushing roller 303 is hollow, and the ultrasonic vibrator 4 is fixedly installed in the hollow part of the material crushing roller 303 and connected to an external electrical controller 19 through a corresponding electrical connection rotary joint 18. The intervention of the electrical connection rotary joint 18 ensures that the ultrasonic vibrator 4 can be effectively used in a rotating environment, thereby significantly improving the practical effect of the present invention.

[0044] The upper part and both sides of the cutting plate 301 are connected to the frame 1 by corresponding buffer rubber sheets 20. The heat softening guide mechanism 5 includes a heating guide plate 501 inclinedly arranged on the lower side of the cutting plate 301. A corresponding electric heater 502 is fixed to the bottom side of the heating guide plate 501. The upper part of the heating guide plate 501 is fixed to the cutting plate 301. The two sides of the heating guide plate 501 are connected to the frame 1 by corresponding heat-resistant rubber sheets 21. A set of guide plates 22 for guiding materials into the primary filter cylinder 601 is provided on the lower side of the heating guide plate 501. In this way, not only can the ultrasonic vibration of the crushing roller 303 be effectively transferred to the cutting plate 301 to improve the crushing effect of the material, but the ultrasonic vibration can also be fully transmitted to the heating guide plate 501 to ensure the stability of the transmission of the crushed material on the heating guide plate 501, and to ensure that the crushed material can pass through the heating guide plate 501 more evenly and loosely, thereby ensuring the heat treatment effect of the crushed material.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
