Description

Technical Field

[0001] This invention belongs to the field of food processing technology, specifically relating to a method for separating seeds, peels and pulp in the processing of sea buckthorn. Background Technology

[0002] Sea buckthorn is a nutrient-rich fruit, containing abundant vitamin C, vitamin E, carotenoids, flavonoids, and various trace elements. Its pulp, peel, and seeds all have significant value in food processing, pharmaceutical preparations, and health product development. The pulp is mainly used in the production of juices, jams, beverages, and functional foods. The peel, rich in dietary fiber and active ingredients, can be used in dietary supplements or for natural pigment extraction. Sea buckthorn seeds are rich in unsaturated fatty acids and protein, possessing high economic value.

[0003] In existing sea buckthorn processing techniques, physical pressing or pulping machines are commonly used to extract the pulp. These methods allow for the initial separation of the raw sea buckthorn pulp from residues such as peels and seeds, achieving a preliminary yield of pulp. However, during this process, sea buckthorn seeds and peels often mix together in the residue, making effective separation difficult. This mixing of seeds and peels not only affects the purity and sensory quality of the pulp but also restricts further processing and utilization of both peels and seeds. For example, dietary fiber and active ingredients from the peel cannot be extracted separately, and the oil or protein components from the seeds cannot be efficiently recovered, thus reducing the overall economic value of the raw materials. Summary of the Invention

[0004] The purpose of this invention is to provide a method for separating seeds, peels, and pulp in sea buckthorn processing. This method achieves efficient and continuous separation of sea buckthorn seeds, peels, and pulp, effectively solving the problem of difficulty in separating seeds and peels in existing sea buckthorn processing methods. This method is simple to operate, highly efficient, and low in cost, meeting the requirements for refined and high-quality sea buckthorn processing.

[0005] The specific technical solution adopted by this invention is as follows: A method for separating seeds, peels and pulp in sea buckthorn processing includes the following steps: Includes the following steps: Step 1: Raw material pretreatment; Step one includes the following steps: 1. Surface pretreatment of sea buckthorn; 2. Sea buckthorn crushing process; Step 2: Pulping and separation treatment; Step two includes the following steps: 1. High-speed pulping and dissociation; 2. Screening and separation; Step 3: Centrifugal separation process; Step three includes the following steps: 1. Differential centrifugal separation; 2. Fruit pulp treatment.

[0006] The seabuckthorn crushing process is carried out using a cage crusher, the pulping and separation process is carried out using a high-speed pulper, and the differential centrifugal separation process is carried out using a horizontal screw centrifuge. The cage crusher, high-speed pulper, and horizontal screw centrifuge are all equipped with a feed end and a discharge end. The high-speed pulper and the horizontal screw centrifuge each have two discharge ends. The two discharge ends of the high-speed pulper are a seed discharge end and a mixed discharge end, respectively. The two discharge ends of the horizontal screw centrifuge are a fruit peel discharge end and a fruit pulp discharge end, respectively. The discharge end of the cage crusher is connected to the feed end of the high-speed pulper, and the mixed discharge end of the high-speed pulper is connected to the feed end of the horizontal screw centrifuge.

[0007] The sea buckthorn surface pretreatment step is carried out using a fruit pretreatment component, which has a feeding port and a discharging port. A conveying plate is installed inside the discharging port, and the end of the conveying plate away from the fruit pretreatment component is located inside the conveying hopper.

[0008] The squirrel cage crusher includes a shell and a servo motor installed at one end of the shell. The feed end of the squirrel cage crusher is a conveying hopper fixed inside the shell. A collecting hood is fixed at the bottom of the conveying hopper and inside the shell. Multiple discharge troughs are provided at the bottom area of ​​the collecting hood. An output shaft is fixed at the output end of the servo motor and inside the collecting hood. Multiple crushing hammers are fixed outside the output shaft. The crushing hammers are clearance-fitted with the inner wall of the collecting hood. A discharge hopper is provided at the bottom of the shell. A guide plate is provided below the discharge hopper. The feed end of the high-speed pulper is a feed hopper adapted to the guide plate. The end of the guide plate away from the discharge hopper is located inside the feed hopper.

[0009] Furthermore, the cage crusher includes a high-speed rotating crushing hammer located in the middle of the cavity. The crushing hammer has a gap of 3mm to 6mm between itself and the inner wall of the cavity, preferably 5mm. A slot with a width of 4mm to 8mm, preferably 5mm, is provided at the bottom of the cavity. Serrated baffles with a height of 8mm to 12mm, preferably 10mm, are provided on both sides of the slot. During the impact, the sea buckthorn fruit forms a circulating disturbance in the cavity and is crushed and torn under the combined action of the hammer and the serrated cavity wall.

[0010] The high-speed pulping machine includes a pulping chamber, a rotor assembly disposed within the pulping chamber, and a screen arranged circumferentially around the pulping chamber. The screen aperture is smaller than the minimum particle size of sea buckthorn seeds, thereby achieving the retention of the seed mixture and the passage of seeds during the pulping process.

[0011] During operation, the rotor assembly strikes and shears the crushed material entering the pulping chamber, causing the seabuckthorn seeds to be screened out by the screen and discharged through the seed discharge end, while the mixture of seabuckthorn pulp and peel fragments is intercepted by the screen and discharged through the mixed discharge end.

[0012] The horizontal screw centrifuge performs solid-liquid centrifugal separation on the mixture discharged from the mixing outlet to obtain sea buckthorn pulp and sea buckthorn peel, respectively. The sea buckthorn pulp is discharged from the pulp outlet, and the sea buckthorn peel is discharged from the peel outlet.

[0013] Both the seed discharge end and the fruit peel discharge end are equipped with guide components. The guide components include a guide hopper and a filter component inside the guide hopper. The filter component includes a filter plate fixed inside the filter component, and multiple conical filter elements are fixed on the filter plate.

[0014] The guiding component is used to guide the material discharge, ensuring that seeds and fruit peels are discharged from their respective discharge ends.

[0015] The pulp processing step is carried out using a pulp grinding device, which is used to refine the sea buckthorn pulp and improve its fluidity.

[0016] The technical effects achieved by this invention are as follows: This invention achieves efficient and continuous separation of pulp, peel, and seeds from sea buckthorn berries by scientifically integrating a cage crusher, a high-speed pulper, and a horizontal screw centrifuge, and precisely optimizing the structural parameters of each device. The cage crusher, through a rationally designed impact gap and a cavity wall structure with serrated baffles, thoroughly crushes the sea buckthorn berries under controlled impact and shearing, while maintaining seed integrity. It also tears the peel to a particle size range of less than 2mm, laying the particle size foundation for subsequent screening and centrifugal separation, effectively improving the three-phase separation efficiency. Compared to the problem of difficult separation of peel and seeds in existing sea buckthorn processing methods, this invention not only significantly improves separation accuracy but also offers advantages such as simple operation, high production efficiency, and low operating costs. It is suitable for large-scale, refined processing of sea buckthorn berries, providing reliable process support and technical assurance for the development of related deep-processed products.

[0019] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0020] like Figure 1-8 As shown, a method for separating seeds, peels, and pulp in sea buckthorn processing includes the following steps: I. Raw material pretreatment Before processing sea buckthorn, the raw materials undergo comprehensive pretreatment to ensure the efficiency and effectiveness of subsequent crushing, pulping, and centrifugal separation. This step includes: 1. Surface pretreatment of sea buckthorn The fruit pretreatment component 10 is used to clean and thaw the collected or transported sea buckthorn fruits, removing impurities, dust, debris and small stones from the fruit surface to ensure that the fruit surface is clean.

[0021] This step ensures that the sea buckthorn berries are in a suitable clean state and temperature, preventing downstream equipment blockages caused by impurities or uneven jelly formation, and improving processing efficiency.

[0022] 2. Seabuckthorn crushing process The cage crusher 1 is used to crush the thawed and washed sea buckthorn fruits. The cage crusher 1 can fully crush the fruits to form crushed materials such as fruit pulp, fruit peel fragments and relatively intact seeds.

[0023] II. Pulping and Separation Process The crushed material is pulped and screened to achieve preliminary separation of seeds from fruit pulp and peel. This step includes: 1. High-speed pulping and dissociation 2. Screening and separation The high-speed pulper 2 is used to beat and shear the crushed material at high speed, so that the fruit peel fragments are fully separated from the fruit pulp, while keeping the seeds intact. During the pulping process, the seeds and the mixture of fruit pulp and fruit peel fragments are discharged from the high-speed pulper 2 and the mixture is transported to the horizontal screw centrifuge 3.

[0024] III. Differential Centrifugal Separation The pulped mixture is then subjected to fine centrifugation to separate the fruit pulp from the peel. This step includes: 1. Differential centrifugal separation A horizontal screw centrifuge (3) is used to separate the solid and liquid components of the mixture after high-speed pulping.

[0025] 2. Fruit pulp treatment Grinding is performed using the fruit pulp grinding device 4.

[0026] Based on the above structure: like Figure 1-7 As shown, the cage crusher 1, the high-speed pulper 2, and the horizontal screw centrifuge 3 are all equipped with a feed end and a discharge end, with the high-speed pulper 2 and the horizontal screw centrifuge 3 each having two discharge ends. The two discharge ends of the high-speed pulper 2 are the seed discharge end and the mixed discharge end, respectively; The two discharge ends of the horizontal screw centrifuge 3 are the fruit peel discharge end and the fruit pulp discharge end, respectively. The discharge end of the cage crusher 1 is connected to the feed end of the high-speed pulper 2 to ensure smooth material conveying. The mixing and discharge end of the high-speed pulper 2 is connected to the feeding end of the horizontal screw centrifuge 3, forming a continuous processing flow.

[0027] Fruit pretreatment component 10 has the following functions and structure: The fruit pretreatment component 10 is an integrated thawing and washing device, combining thawing and washing functions for preliminary processing of harvested sea buckthorn berries. This device achieves rapid thawing of the berries by controlling the temperature and washing medium, while simultaneously removing dust, impurities, small stones, and other foreign matter from the fruit surface, ensuring a clean fruit surface and suitable temperature, thus providing a stable raw material state for subsequent crushing, pulping, and centrifugal separation.

[0028] like Figure 1-7 As shown, the fruit pretreatment component 10 is provided with a feeding port and a discharging port. A conveying plate 7 is installed inside the discharging port, and the end of the conveying plate 7 away from the fruit pretreatment component 10 extends to the inside of the conveying hopper 8. After thawing and cleaning, the sea buckthorn berries are evenly fed into the cage crusher 1 through the coordinated conveying action of the conveying plate 7 and the conveying hopper 8, ensuring that the material entering the cage crusher 1 is continuous and uniform, and avoiding local blockage and uneven crushing.

[0029] The squirrel cage crusher 1 includes a shell 21 and a servo motor installed at one end of the shell 21. The feed end of the squirrel cage crusher 1 is a conveying hopper 8 fixed inside the shell 21. A material collection hood 9 is fixed at the bottom of the hopper 8 and inside the housing 21. Multiple discharge troughs 13 are provided at the bottom area of ​​the material collection hood 9. An output shaft 11 is fixed at the output end of the servo motor and inside the material collection hood 9. Multiple crushing hammers 12 are fixed on the outside of the output shaft 11. The crushing hammers 12 are clearance-fitted with the inner wall of the material collection hood 9. A discharge hopper 14 is provided at the bottom of the housing 21. A guide plate 6 is provided below the discharge hopper 14. The feed end of the high-speed pulper 2 is a feed hopper 5 adapted to the guide plate 6. The end of the guide plate 6 away from the discharge hopper 14 is located inside the feed hopper 5.

[0030] When using the cage crusher 1, the thawed and cleaned sea buckthorn fruits are conveyed into the collection hood 9 by the conveying hopper 8. The servo motor drives the output shaft 11 to rotate, and the crushing hammer 12 impacts and shears the fruits in the collection hood 9 to achieve crushing. After crushing, the crushed material enters the discharge hopper 14 through the discharge chute 13, and is then sent into the high-speed pulping machine 2 by the discharge hopper 14 and the guide plate 6.

[0031] In the cage crusher, a high-speed rotating crushing assembly is installed in the middle of the cavity. The crushing hammer 12, in operation, repeatedly impacts the falling seabuckthorn berries with high-speed rotation, causing the berries to break. A gap of 3mm to 6mm, preferably 5mm, is provided between the hammer and the inner wall of the cavity to control the crushed particle size, prevent seed breakage, and simultaneously promote thorough tearing of the pericarp. A groove approximately 4mm to 8mm wide, preferably 5mm, is provided at the bottom of the cavity, with serrated baffles 8mm to 12mm high, preferably 10mm, on both sides, forming a rough cavity wall structure. After high-speed impact, the seabuckthorn berries, under the combined action of the serrated cavity wall and the hammer, create a circulating disturbance, further tearing the pericarp into pericarp fragments with a particle size of less than 2mm. The pulp, pericarp fragments, and seeds, under the action of gravity and compression, flow through the groove into the collection tank located below, forming a pulp-permeable-seed mixture flow, providing conditions for subsequent pulping and separation steps. Sea buckthorn seeds are round, with a diameter ranging from 2 to 3.5 mm, which is conducive to separation from fruit peel fragments and pulp due to particle size differences.

[0032] like Figure 1-7 As shown, the high-speed pulper 2 includes a pulping chamber, a rotor assembly inside the pulping chamber, and a screen 15 surrounding the pulping chamber. When using the high-speed pulper 2, the crushed material is subjected to high-speed impact and shearing under the action of the rotor assembly, so that the fruit peel fragments are fully separated from the pulp, while keeping the seeds intact. The sieve mesh 15 has a mesh size 22 smaller than the smallest particle size of sea buckthorn seeds, but larger than the size of most fruit peel fragments. The mesh size 22 is between 1.5 mm and 2.2 mm, preferably 1.8 mm, so that the seeds can pass through the sieve mesh 15 and be discharged from the seed discharge end, while the pulp and fruit peel fragments are discharged through the mixed discharge end to the horizontal screw centrifuge 3.

[0033] The two discharge ends of the horizontal screw centrifuge 3 are the peel discharge end and the pulp discharge end. The horizontal screw centrifuge 3 uses centrifugal force to throw the peel to the outside and discharge it from the peel discharge end, while the pulp is located on the inside and discharges it from the pulp discharge end, thus achieving fine separation.

[0034] like Figure 1-7 As shown, both the seed discharge end and the fruit peel discharge end are provided with guide components 16. The guide component 16 includes a guide hopper 17 and a filter component 18 inside the guide hopper 17. The filter component 18 includes a filter plate 19 fixed inside the guide hopper 17 and a plurality of conical filter elements 20 fixed inside the filter plate 19. The feed hopper 17 is used to guide the material to be discharged smoothly, ensuring that seeds and fruit peels are discharged from their respective discharge ends to avoid cross-mixing. The filter plate 19 and the conical filter element 20 are used to assist in filtering and guiding the discharged material, which can prevent larger fruit peels or foreign objects from entering the discharge end and ensure that seeds and fruit peels do not flow back or mix in during the discharge process.

[0035] The shape of the cone-shaped filter element 20 can guide seeds or fruit peels to be discharged smoothly in a predetermined direction, reducing clogging and accumulation; like Figure 1 and 8 As shown, the final fruit pulp enters the fruit pulp grinding device 4 through the fruit pulp discharge end. The fruit pulp grinding device 4 grinds the fruit pulp to further refine the particles and improve its fluidity, providing a good material state for subsequent sterilization and packaging.

[0036] To verify the improved technical performance resulting from the structural optimization of this invention, the applicant conducted a comparative experiment. The experiment compared a traditional three-step sea buckthorn processing line (ordinary hammer crusher + conventional pulper + horizontal screw centrifuge) with the structurally optimized combination described in this invention. Under the same raw material processing conditions, the results are as follows: In traditional processes, due to inaccurate control of crushed particle size, the size of fruit peel fragments is generally larger than 3mm, and some seeds are accidentally crushed, resulting in low efficiency of subsequent pulping and screening and poor pulp purity. The three-phase separation process requires secondary screening or manual intervention, with an average processing efficiency of 200 kg of raw materials per hour.

[0037] In this invention, by setting a 5mm gap between the crushing hammer and the chamber of the cage crusher, setting 10mm serrated baffles, and a 5mm groove, the particle size of sea buckthorn berries is controlled within the target range during efficient impact and shearing. The size of the pericarp in the crushed material is consistently below 2mm, and the seeds remain intact. Combined with a 1.8mm pulping screen and optimized centrifugal speed, the pulp, pericarp, and seeds can be separated in one pass, increasing the overall processing efficiency to over 450 kg per hour, more than doubling the efficiency.

[0038] The experiment further showed that if any of the above key structural parameters (such as the gap between the crushing hammers) were changed to more than 8 mm, the seed breakage rate would increase significantly, the size of the pericarp fragments would be too large and unable to pass through the sieve, and the three-phase separation efficiency would drop to less than 70%, which verified the synergistic optimization relationship between the parameters.

[0039] Therefore, it can be seen that this invention is not merely a simple series connection of equipment, but rather a system-integrated seabuckthorn separation process solution constructed through structure-process coupling design, achieving multi-dimensional improvements in yield, purity, and automation level, demonstrating outstanding technological progress, which cannot be directly derived from existing technologies.

[0040] In summary, this invention achieves efficient and continuous separation of sea buckthorn seeds, peels, and pulp by rationally configuring and optimizing the cage crusher 1, high-speed pulper 2, and horizontal screw centrifuge 3, and by scientifically adjusting the structure and parameters of each piece of equipment. Compared with the prior art, the main beneficial effects of this invention are reflected in the following aspects: Effective separation of seeds and peel: This solves the problem of difficulty in separating seeds and peel in existing sea buckthorn processing, enabling efficient separation of pulp, peel fragments and seeds in the same processing flow, avoiding the mixing of peel and seeds in traditional methods.

[0041] Continuous and efficient process: Raw materials are continuously processed through pretreatment, crushing, pulping and centrifugal separation, achieving fully automated conveying, significantly improving production efficiency and reducing manual intervention and material stagnation.

[0042] Improved pulp quality: Through pulping and centrifugation, the pulp particles are further refined and have good flowability, providing high-quality raw materials for subsequent sterilization, packaging and deep processing, meeting the requirements of refined processing.

[0043] Easy to operate and low cost: The process is reasonably connected, the material is transported smoothly, the equipment wear is low, the energy consumption and maintenance costs are reduced, and the operation is simple and suitable for large-scale production.

[0044] Adapting to deep processing and product development: Enabling graded utilization of sea buckthorn raw materials, seeds, peels, and pulp can be used for different product development, providing a reliable technical foundation for deep processing of sea buckthorn, and improving economic benefits and resource utilization.

[0045] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
