Description

Technical Field

[0001] The present invention relates to the technical field of fruit juice processing, and specifically to a processing device and method for Doinia indica fruit juice. Background Art

[0002] The fruits of Doinia indica in Yunnan are traditional Chinese medicinal materials, which can be used as medicine to treat diarrhea, promote digestion and strengthen the stomach, and expel worms. In Yunnan folk, Doinia indica fruits are also used as ripening agents for persimmons. Doinia indica in Yunnan can also be made into preserved fruits, fruit vinegar, and beverages for consumption. Doinia indica fruit beverages are sour and sweet, and are excellent products for relieving heat and summer heat.

[0003] However, the water content of Doinia indica fruits is not high, so the juice yield of Doinia indica fruits is not high. Existing juicing technologies generally use toothed roll crushers. By the high-speed rotation of toothed rolls and blades, the juice yield of Doinia indica fruits is increased. However, this method has certain defects. This high-speed rotation crushing method also greatly pulverizes plant fibers. These overly pulverized plant fibers are mixed with the fruit juice to form a pulp-like substance, which will greatly increase the difficulty of separating fruit residues and fruit juice in the subsequent process and affect the overall production line operation efficiency.

[0018] A processing method for Duoyi fruit juice is also disclosed, including the following steps:

[0019] S1. Prepare raw materials: Select fresh and ripe Duoyi fruits as raw materials. Blanch the washed Duoyi fruits in warm water or steam at 78°C - 80°C for 2.75 minutes - 3 minutes, and then drain the water. The purpose of blanching is to remove oxidase, prevent the further oxidation of Duoyi fruits, make the juice color show light yellowish green, and at the same time soften the fruits for squeezing;

[0020] According to the needs of juice processing, select a suitable enzyme preparation as an auxiliary material for juicing.

[0021] S2. Feed raw materials: Quickly feed the prepared Duoyi fruits through the feeding port of the pretreatment chassis, and act on the extrusion and crushing parts inside the feeding port. Crush the Duoyi fruits by means of jaw extrusion and crushing, and set the crushing parameters. It is appropriate to crush the Duoyi fruits into 8 - 10 petals.

[0022] S3. Refinement treatment: Start the processing parts. The juice turning plate group continuously turns the fruit materials through mechanical linkage. The turning frequency is preferably 10 - 15 times per minute; Drive the pressing drive bracket, and the juice pressing frame group reciprocally presses the turning fruit materials under the drive of the pressing drive bracket. The pressing pressure should be adjusted according to the hardness of the fruit materials and the juicing requirements, generally not exceeding 500 kg / cm², and the pressing time for each time is 5 - 10 seconds.

[0023] S4. Add enzyme preparation: While performing the refinement treatment step, synchronously add the enzyme preparation. The addition amount of the enzyme preparation should be adjusted according to factors such as the type of fruit materials and the juice viscosity. It is appropriate to add 0.1 - 0.5 kg of enzyme preparation per 100 kg of fruit materials.

[0024] S5. Collecting the juice: After the above steps, the juice will flow out of the equipment chassis and be collected into a designated container. The collecting container should be clean and sterile to avoid juice contamination. The filtering equipment uses a microporous membrane filtering device to filter the juice to remove impurities and suspended matter.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] The pretreatment chassis facilitates the seamless connection between the preliminary treatment of raw materials and the subsequent juice extraction process. Inside the feeding port, an extrusion and crushing component is installed. The extrusion and crushing component adopts the method of jaw extrusion and crushing, which can effectively crush the docynia indica fruits, reduce the generation of fruit residues, and improve the juice yield. Inside the equipment chassis, a set of efficient processing components is supported by a processing support frame. The juice extraction pressing frame group is located outside the juice extraction turning plate group. By applying appropriate pressure, it helps to further extract the residual juice from the fruit material and increase the juice output. The juice extraction pressing frame group presses and combines reciprocally, and the juice extraction turning plate group continuously turns the fruit material, causing the fruit material to scrape and impact with the juice extraction pressing frame group. These actions help to squeeze out the juice in the fruit material more thoroughly and improve the juice extraction efficiency. Through the rapid crushing of the pretreatment chassis, the reciprocal pressing of the juice extraction pressing frame group, and the continuous turning of the juice extraction turning plate group, the present invention can significantly improve the juice extraction efficiency of docynia indica fruits and shorten the processing cycle. At the same time, by optimizing the juice extraction process, it can reduce the generation of fruit residues, avoid excessive crushing of fruit residues, avoid excessive mixing of fruit residue fragments and juice, improve the juice output and quality, facilitate the operation of the subsequent juice separation process, and improve the operation efficiency of the overall docynia indica fruit juice extraction production line.

When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0039] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] The following is a detailed description of the specific implementation of the present invention in conjunction with specific embodiments.

[0041] In one embodiment, please refer to Figures 1 to 3 , a processing device for loquat juice is provided, including an equipment base 11 and an equipment chassis 12 erected on the equipment base 11. A pretreatment chassis 21 is further provided on the top of the equipment chassis 12. The pretreatment chassis 21 includes a feeding box 22. The bottom of the feeding box 22 is installed on the box body of the equipment chassis 12 through a turnover frame 23 and is communicated with the inner cavity of the box body of the equipment chassis 12. A feeding port 24 is provided at the top of the feeding box 22, and an extrusion crusher part 25 is installed in the feeding port 24. A processing operation part 14 is erected in the box body of the equipment chassis 12 through a processing support frame 13. A plurality of juice extraction turning plate groups 15 are installed on the periphery of the processing operation part 14. A juice extraction pressing frame group 17 is further provided in the box body of the equipment chassis 12. The juice extraction pressing frame group 17 is located on the periphery of the juice extraction turning plate groups 15. A pressing drive support frame 16 for driving the juice extraction pressing frame group 17 is provided on the box wall of the equipment chassis 12.

[0042] This embodiment provides a processing device for loquat juice, aiming to efficiently and automatically complete the juice extraction process of loquats. The equipment base 11 serves as the support structure of the entire device and is made of strong and durable metal materials to ensure the stable operation of the entire device. The equipment chassis 12 is erected on the equipment base 11, and its internal design has a reasonable space layout for installing various processing components. A pretreatment chassis 21 is provided at the top of the equipment chassis 12, and this design facilitates the seamless connection between the preliminary treatment of raw materials and the subsequent juice extraction process.

[0043] The main body of the pretreatment chassis 21 is the feeding box 22, which is stably installed on the box body of the equipment chassis 12 through the turnover frame 23, forming a sealed and connected channel between the two, ensuring that the loquats can directly enter the equipment chassis 12 for the next step of processing after being crushed. A spacious feeding port 24 is opened at the top of the feeding box 22, facilitating the rapid input of raw materials. Inside the feeding port 24, an extrusion crusher part 25 is installed. The extrusion crusher part 25 adopts the method of jaw extrusion crushing, which can effectively crush loquats while reducing the generation of fruit residue and improving the juice yield. Inside the equipment chassis 12, a set of efficient processing operation parts 14 is supported by a processing support frame 13, which is responsible for further refining the crushed fruit material and squeezing out the juice. In order to improve the juice extraction efficiency, a plurality of juice extraction turning plate groups 15 are carefully arranged on the periphery of the processing operation part 14. These turning plate groups are mechanically linked and can continuously turn the fruit material during the juice extraction process, cooperating with the juice extraction pressing frame group 17 provided in the equipment chassis 12 for further operation processing. The juice extraction pressing frame group 17 is located on the periphery of the juice extraction turning plate groups 15. By applying appropriate pressure, it helps to further squeeze out the residual juice in the fruit material and improve the juice output.

[0044] The juice extraction pressing frame group 17 is located on the periphery of the juice extraction turning plate group 15, and realizes reciprocating pressing actions through the drive of the pressing drive bracket 16. The pressing drive bracket 16 can adopt a combination of a servo motor and a reducer, which can accurately control the movement speed and strength of the juice extraction pressing frame group 17, ensuring that juice can be effectively extracted during the juice extraction process and avoiding adverse effects on the juice quality. The juice extraction pressing frame group 17 reciprocates to press, and the juice extraction turning plate group 15 continuously turns the fruit material, causing the fruit material to scrape and impact with the juice extraction pressing frame group 17. These actions help to squeeze out the juice in the fruit material more thoroughly and improve the juice extraction efficiency.

[0045] In this embodiment, through the rapid crushing of the pretreatment chassis, the reciprocating pressing of the juice extraction pressing frame group 17, and the continuous turning of the juice extraction turning plate group, the juice extraction efficiency of the Indian mulberry can be significantly improved, and the processing cycle can be shortened. At the same time, by optimizing the juice extraction process, the generation of fruit residue can be reduced, the over-crushing of fruit residue can be avoided, the excessive mixing of fruit residue fragments and juice can be avoided, the yield and quality of the juice are improved, which is beneficial to the operation of the subsequent juice separation process and improves the operation efficiency of the overall Indian mulberry juice extraction production line.

[0046] In one embodiment, please refer to Figure 2 and Figure 4 , as a further design of the above embodiment, on this basis, for the specific implementation structure of the pretreatment chassis 21, this embodiment is designed as follows:

[0047] A blanking port 31 is provided at the bottom of the inner box of the feeding box 22. The blanking port 31 is used to connect the inner cavity of the feeding box 22 and the equipment chassis 12. A fixed toothed plate 32 is provided on one side of the blanking port 31, and a movable extrusion frame 33 is provided on the other side of the blanking port 31. A movable toothed plate 34 corresponding to the fixed toothed plate 32 is provided on the movable extrusion frame 33. A V-shaped channel is formed between the fixed toothed plate 32 and the movable toothed plate 34. The top of the movable extrusion frame 33 is swingably installed on the box wall of the feeding box 22 through an extrusion frame swing support shaft 47. A fixed angle bracket 41 is also installed on the box wall of the feeding box 22, a shaft support 42 provided on the fixed angle bracket 41, a swing shaft 43 installed on the shaft support 42, and a swing arm 44 provided on the swing shaft 43. A push-pull frame 45 is installed at the end of the swing arm 44. The push-pull frame 45 is connected to the bottom of the extrusion frame swing support shaft 47 through a front connecting bolt 46.

[0048] The blanking port 31 serves as a channel connecting the feeding box 22 and the inner cavity of the equipment chassis 12. A fixed toothed plate 32 is provided on one side of the blanking port 31, while a movable extrusion frame 33 and a movable toothed plate 34 are provided on the other side. The movable extrusion frame 33 and the movable toothed plate 34 are the main working bodies of the extrusion crusher part 25. The V-shaped channel formed between the fixed toothed plate 32 and the movable toothed plate 34 is used to gradually reduce the gap between the fruit materials. During operation, when the swing arm 44 is subjected to an external force, it can drive the movable extrusion frame 33 to swing around the swing support shaft 47 of the extrusion frame. Through the periodic approach and separation of the movable extrusion frame 33 and the fixed toothed plate 32, the fruit materials are extruded, split, and bent and broken, achieving an efficient crushing effect. This crushing method can quickly crush the Duoyi fruits into granular shapes suitable for juicing, providing good pretreatment conditions for the subsequent juicing process.

[0049] Regarding the driving method of the movable extrusion frame 33, the present embodiment is designed as follows:

[0050] A rotating wheel 51 is installed on the swing shaft 43. A driving motor 52 is provided on the outer edge of the feeding box 22. A transmission belt 53 is provided at the driving end of the driving motor 52. A supporting roller 54 is also provided between the driving motor 52 and the rotating wheel 51. The transmission belt 53 is tightened by the supporting roller 54 and connected between the driving end of the driving motor 52 and the rotating wheel 51.

[0051] On the outer edge of the feeding box 22, a driving motor 52 is provided as the power source for the swing of the movable extrusion frame 33. Through the coordinated action of the driving motor 52, the transmission belt 53, and the rotating wheel 51, the smooth and continuous power transmission is ensured. In order to ensure the stable operation of the transmission belt 53, a supporting roller 54 is installed between the driving motor 52 and the rotating wheel 51. The function of the supporting roller 54 is to tighten the transmission belt 53 and prevent it from loosening or shifting during operation, thereby ensuring the accuracy and reliability of power transmission.

[0052] Regarding the control of the swing frequency and extrusion force of the movable extrusion frame 33, the present embodiment is designed as follows:

[0053] A rear connecting bolt 63 is further connected to the frame end of the swing arm 44. A swing sensor 61 is provided inside the box body of the feeding box 22. The rear connecting bolt 63 is connected to the swing sensor 61 through a folding frame 62. The sensing end of the swing sensor 61 is electrically connected to the power control end of the driving motor 52.

[0054] At the frame end of the swinging boom 44, a rear connecting bolt 63 is specially designed. The folding frame 62 is connected to the swing sensor 61, forming a sensor system capable of real-time sensing of the motion state of the swinging boom 44. The swing sensor 61 is a high-precision and high-sensitivity sensor, which can monitor key parameters such as the swing angle, speed and acceleration of the swinging boom 44 in real time. These parameters are transmitted to the power control end of the drive motor 52 in the form of electrical signals in real time. The power control end of the drive motor 52 then precisely adjusts the speed and torque of the motor according to the received electrical signals. When the swing sensor 61 senses a change in the swing frequency or swing angle of the swinging boom 44, it immediately sends corresponding electrical signals to the drive motor 52. The drive motor 52 then adjusts its speed and torque according to these signals, thereby achieving precise control of the swing frequency and extrusion force of the movable extrusion frame 33. This control method not only ensures the stability and accuracy of the movable extrusion frame 33 during the jaw extrusion crushing process, but also improves the overall operating efficiency and juice quality of the equipment. It enables the equipment to automatically adapt to Duoyi fruit materials of different sizes and hardnesses, realizing flexible processing of Duoyi fruit materials.

[0055] In one embodiment, please refer to Figure 3 , Figure 5 and Figure 6 , based on this embodiment as a further design of the above embodiment, for the specific implementation structure of the processing workpiece 14, this embodiment is designed as follows:

[0056] The processing support frame 13 includes a fixed frame 71 installed on the equipment base 11. A fixed bearing 72 is installed on the fixed frame 71. The processing workpiece 14 includes a driving main shaft 82 and a plurality of rotating disks 83 installed on the driving main shaft 82. The shaft end of the driving main shaft 82 is supported within the fixed bearing 72. The rotating disks 83 are arranged in the inner cavity of the equipment chassis 12. The juice squeezing turning plate group 15 is installed on the rotating disks 83. A plurality of concave card slots 92 are equiangularly arranged on the disk body of the rotating disk 83. The juice squeezing turning plate group 15 is composed of a plurality of turning support plates 91 arranged in parallel. Each turning support plate 91 is installed in the concave card slot 92 of the corresponding rotating disk 83. A scraping block 96 is arranged on the plate body of the turning support plate 91, and the outer end of the plate body of the turning support plate 91 is bent and formed with a material scraping protrusion 97.

[0057] The processing support frame 13 is mainly composed of a fixed frame 71 installed on the equipment base 11. The fixed frame 71 is designed to be strong and can withstand various forces and vibrations generated during the processing. The fixed bearing 72 serves as the support point for driving the main shaft 82, ensuring the stable rotation of the main shaft. The rotating disk 83 is evenly installed on the driving main shaft 82 and rotates with the rotation of the main shaft. The juice squeezing turning plate group 15 is composed of several turning support plates 91 arranged in parallel. Each turning support plate 91 is precisely installed in the concave card slot 92 of the corresponding rotating disk 83, ensuring a tight fit between the support plate and the disk body. The scraping block 96 can effectively scrape the fruit material during rotation, promoting the extraction of juice. The design of the material scraping protrusion 97 can push the fruit material from the center of the disk body to the edge during rotation, so as to cooperate with the juice squeezing pressing frame group 17.

[0058] Regarding the installation implementation method of the turning support plate 91, this embodiment is designed as follows:

[0059] A clamping groove 93 is provided on the plate body of the turning support plate 91. An insertion block 94 is installed on the clamping groove 93. An installation bolt 95 is provided on one side of the notch of the concave card slot 92, and the insertion block 94 is locked and fixed with the installation bolt 95. The juice squeezing turning plate group 15 includes an integrated substrate 98. Fixed groove blocks 99 are provided on the plate bodies of the turning support plates 91. The integrated substrate 98 is installed on the other side of the notch of the concave card slot 92, and the turning support plates 91 in the same row are all fixed to the integrated substrate 98 through the fixed groove blocks 99.

[0060] On the plate body of the turning support plate 91, a clamping groove 93 is designed, which enables the turning support plate 91 to be easily inserted into the concave card slot 92 of the rotating disk 83. To further enhance the connection stability, an insertion block 94 is installed on the clamping groove 93 on one side of the notch of the concave card slot 92. The shape and size of the insertion block 94 match the notch of the concave card slot 92 and can be tightly inserted therein. To further improve the overall stability and durability of the juice squeezing turning plate group 15, an integrated substrate 98 is also designed. The integrated substrate 98 is a strong flat plate structure that can closely fit on the other side of the notch of the concave card slot 92 of the rotating disk 83. Fixed groove blocks 99 are provided on the turning support plates 91 in the same row, and these fixed groove blocks 99 can match the corresponding structures on the integrated substrate 98, thereby ensuring the firm fixation of the turning support plates 91 on the integrated substrate 98. This design of this embodiment enhances the overall stability and durability of the juice squeezing turning plate group 15, making the entire juice squeezing process more stable and reliable.

[0061] In one embodiment, please refer to Figure 5 and Figure 7, in order to improve the juicing effect, the driving main shaft 82 is a hollow shaft body and is externally connected with an enzyme preparation pipeline 81, and a plurality of enzyme preparation inlets 84 are opened on the shaft wall of the driving main shaft 82.

[0062] Appropriate amounts of enzyme preparations such as pectinase and cellulase are added. These enzymes can decompose pectin and cellulose in the pulp, reduce the viscosity of the juice, and thus increase the juice yield. In order to achieve the precise delivery of the enzyme preparation, we have opened a plurality of enzyme preparation inlets 84 on the shaft wall of the driving main shaft 82. The design of these inlets 84 is very ingenious. They can evenly spray the enzyme preparation onto the rotating fruit material, ensuring that every part of the fruit material can be fully enzymatically hydrolyzed. During the juicing process, the enzyme preparation is transported to the inside of the driving main shaft 82 through the enzyme preparation pipeline 81, and then, as the main shaft rotates, it is evenly sprayed onto the rotating fruit material through the inlets 84. After the enzyme preparation comes into full contact with the fruit material, it starts to play its catalytic role and accelerates the juice extraction process.

[0063] In one embodiment, please refer to Figure 3 and Figure 8 , as a further design of the above embodiment, on this basis, for the specific implementation structure of the juice pressing and fitting frame group 17, the design of this embodiment is as follows:

[0064] The pressing drive bracket 16 includes a fixed outer frame 101, a support plate 102, and a piston rod 103. The support plate 102 is fixed on the box wall of the equipment chassis 12. The piston rod 103 is installed on the fixed outer frame 101 and extends into the box of the equipment chassis 12 through the support plate 102. The telescopic rod end of the piston rod 103 is connected to the juice pressing and fitting frame group 17. The juice pressing and fitting frame group 17 includes an arc-shaped scraping frame 104. The arc-shaped scraping frame 104 is an arched frame structure and its arched curved surface faces the periphery of the juice turning plate group 15. A plurality of scraping base blocks 105 are arranged on the frame body of the arc-shaped scraping frame 104. The scraping base blocks 105 are trapezoidal blocks. A convex platform portion 106 is formed at the bottom of the scraping base blocks 105. The scraping base blocks 105 in the same row are arranged in alignment, and the scraping base blocks 105 in the same column are arranged in a stepped manner and the convex platform portion 106 is exposed. A plurality of pointed convex blocks 107 are also arranged on the surface of the scraping base blocks 105; the turning support plate 91 turns towards the direction of the arc-shaped scraping frame 104 and the material scraping protrusion 97 bends towards this direction.

[0065] The piston rod 103 is externally connected to a servo motor as the power end. Through the telescopic movement of the piston rod 103, the juice extraction and pressing frame group 17 is driven to perform periodic actions. The core component of the juice extraction and pressing frame group 17 is the arc-shaped scraping frame 104, which adopts an arched frame structure, and its arched curved surface cleverly faces the periphery of the juice extraction turning plate group 15. This design enables the arc-shaped scraping frame 104 to more effectively scrape and press the fruit material during the pressing process, improving the juice extraction efficiency. Inside the frame of the arc-shaped scraping frame 104, scraping material base blocks 105 are filled and installed. These scraping material base blocks 105 are in the shape of stepped blocks, and their bottoms form convex portions 106. The scraping material base blocks 105 in the same row are arranged in alignment to ensure the uniformity of scraping the fruit material; while the scraping material base blocks 105 in the same column are arranged in a stepped pattern. This design not only enhances the strength and stability of the scraping frame but also enables the convex portions 106 to be exposed, thereby more effectively scraping and pressing the fruit material. The pointed convex blocks 107 on the surface of the scraping material base blocks 105 can play a role in crushing and pressing when scraping the fruit material, further improving the juice extraction efficiency and quality.

[0066] During the juice extraction process, the turning support plate 91 in the juice extraction turning plate group 15 will turn towards the direction of the arc-shaped scraping frame 104. At the same time, the material scraping protrusion 97 assists in scraping and contacting the fruit material in the area of the arc-shaped scraping frame 104, and the fruit material can be naturally pushed towards the arc-shaped scraping frame 104. The scraping material base blocks 105 and the pointed convex blocks 107 on the arc-shaped scraping frame 104 then play a further role in pressing and tearing, and they can penetrate into the fiber structure of the fruit material to help the juice seep out better.

[0067] To further elaborate on the operation mode of the present invention, a method for processing Duoyi fruit juice is also disclosed, including the following steps:

[0068] S1. Prepare raw materials: Select fresh and ripe Duoyi fruits as raw materials. Blanch the washed Duoyi fruits in warm water or steam at 78°C - 80°C for 2.75 minutes - 3 minutes, and then drain the water. The purpose of blanching is to remove oxidase, prevent the further oxidation of Duoyi fruits, make the juice color show light yellowish green, and at the same time soften the fruits for pressing;

[0069] According to the needs of juice processing, select a suitable enzyme preparation as an auxiliary material for juice extraction.

[0070] S2. Feed raw materials: Quickly feed the prepared Duoyi fruits through the feeding port 24 of the pretreatment machine box 21 into the internal extrusion and crushing parts 25 of the feeding port 24. Crush the Duoyi fruits by means of jaw extrusion and crushing, and set the crushing parameters. It is appropriate to crush the Duoyi fruits into 8 - 10 pieces.

[0071] S3. Refinement processing: Start the processing workpiece 14. The juice extraction turning plate group 15 continuously turns the fruit material through mechanical linkage. The turning frequency is preferably 10 - 15 times per minute; Drive the pressing drive bracket 16. The juice extraction pressing frame group 17 reciprocally presses the turning fruit material under the drive of the pressing drive bracket 16. The pressing pressure should be adjusted according to the hardness of the fruit material and the juice extraction requirements, generally not exceeding 500 kg / cm², and the pressing time for each time is 5 - 10 seconds.

[0072] S4. Adding enzyme preparation: While performing the refinement processing step, synchronously add the enzyme preparation. The addition amount of the enzyme preparation should be adjusted according to factors such as the type of fruit material and the juice viscosity, and it is preferably 0.1 - 0.5 kg of enzyme preparation per 100 kg of fruit material.

[0073] S5. Collecting juice: After the above steps, the juice will flow out from the equipment chassis 12 and be collected into a designated container. The collection container should be clean and sterile to avoid juice contamination. The filtration equipment uses a microporous membrane filtration device to filter the juice to remove impurities and suspended substances.
