Description

Technical Field

[0001] This invention relates to a device for separating sea buckthorn bark and seeds. Background Technology

[0002] In the existing industrial processing technology of sea buckthorn, conventional equipment relies on simple pressing, single screening or vibration screening to separate the skin and seeds, resulting in a single sorting method and poor targeting.

[0003] Because the sea buckthorn pods are soft and easily trap small seeds, traditional equipment cannot effectively break through the seed-covering structure. This often results in small seeds being embedded or mixed in with the pod material, leading to incomplete seed separation and high loss rates.

[0004] Therefore, a sea buckthorn peel and seed separation device is proposed to address the above problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing devices and provide a sea buckthorn peel and seed separation device with a high sea buckthorn peel and seed separation rate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sea buckthorn peel and seed separation device, comprising: Feed hopper, cold pulping and separation unit, sugar dissolving and pressing unit, mixing and bulk material unit, multi-stage sorting and filtration unit and collection tank; The cold pulping and separation component, the sugar dissolving and pressing component, the mixing and dispersing component, and the multi-stage sorting and filtration component are connected in series. The feed end of the cold pulping and separation component is connected to the feed hopper; the discharge end of the multi-stage sorting and filtering component is connected to the collection tank.

[0007] Preferably, the cold pulping and separation assembly includes: A double-stage cold beater, wherein the feed end of the double-stage cold beater is connected to a first screw pump, and the other end of the first screw pump is connected to the feed hopper; The juice outlet of the double-channel cold pulping machine is connected to a first fruit pulp temporary storage tank; the residue outlet is connected to a first sugar washing tank.

[0008] Preferably, the sugar-dissolving pressing assembly includes: A screw press, wherein the feed end of the screw press is connected to a second screw pump, and the other end of the second screw pump is connected to the first sugar washing tank; The juice outlet of the screw press is connected to a second pulp storage tank; the residue outlet is connected to a dispersion tank.

[0009] Preferably, the mixing bulk material assembly includes: A first cyclone separator, the feed end of which is connected to a third screw pump, and the other end of the third screw pump is connected to the dispersion tank; The juice outlet of the first cyclone separator is connected to a third temporary storage tank; the residue outlet is connected to a first seed collection tank.

[0010] Preferably, the multi-stage sorting and filtering component includes: The second cyclone separator has its feed end connected to the fourth screw pump, and the other end of the fourth screw pump is connected to the third temporary storage tank. The slag outlet of the second cyclone separator is connected to a second seed collection tank.

[0011] Preferably, the multi-stage sorting and filtering component further includes: The scraper refining machine has its feed end connected to the juice outlet of the second cyclone separator, its slag outlet connected to a colloid mill, and its discharge outlet connected to the collection tank.

[0012] Preferably, the top of the first sugar washing tank is provided with a first water inlet for adding high-temperature hot water.

[0013] Preferably, the top of the dispersion tank is provided with a second inlet for adding high-temperature hot water.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: This seabuckthorn peel and seed separation device, by setting up a cold-beating pulping and separation component, a sugar-dissolving and pressing component, a stirring and dispersing component, and a multi-stage sorting and filtration component, adopts an integrated process of low-temperature cold beating, high-temperature sugar-dissolving and pressing, high-speed stirring and dissociation, two-stage cyclone sorting, and fine filtration pulping, which can achieve efficient separation and comprehensive utilization of seabuckthorn peel, seeds, and sugar. The separation rate of seabuckthorn fruit and seeds in this device can reach 99.8%, effectively solving the problems of fruit and seed embedding, incomplete sorting, and high loss in traditional processes. The obtained fruit and seeds have high purity and can be directly used for deep processing, significantly improving product quality and recovery rate.

[0015] Meanwhile, this device can fully utilize the sea buckthorn peel. After separation and purification, the peel is ground into a fine pulp using a colloid mill, preserving the active ingredients and avoiding waste. Furthermore, by combining high-temperature hot water sugar dissolution with pressing, soluble sugars in the residual pulp and peel of sea buckthorn can be thoroughly extracted, resulting in high sugar extraction and recovery rates.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1-5 As shown, a sea buckthorn peel and seed separation device includes a feeding hopper 1, a cold pulping and separation component, a sugar dissolving and pressing component, a mixing and dispersing component, a multi-stage sorting and filtering component, and a collection tank 2; the cold pulping and separation component, the sugar dissolving and pressing component, the mixing and dispersing component, and the multi-stage sorting and filtering component are connected in series; the feeding end of the cold pulping and separation component is connected to the feeding hopper 1; the discharging end of the multi-stage sorting and filtering component is connected to the collection tank 2.

[0020] Specifically, the cold pulping and separation assembly includes a double-stage cold pulper 3, with the feed end of the double-stage cold pulper 3 connected to a first screw pump 4, and the other end of the first screw pump 4 connected to a feed hopper 1; the juice outlet of the double-stage cold pulper 3 is connected to a first fruit pulp storage tank 5; and the residue outlet is connected to a first sugar washing tank 6. The top of the first sugar washing tank 6 is provided with a first water inlet for adding high-temperature hot water.

[0021] Specifically, the pre-treated and impurity-removed sea buckthorn berries are fed into the feed hopper 1 and stably transported to the double-stage cold pulping machine 3 by the first screw pump 4. The equipment adopts a low-temperature pulping mode throughout the process, which gently crushes and pulps the fresh sea buckthorn berries without damaging the active nutrients inside the sea buckthorn. The sea buckthorn pulp is initially separated from the mixture of peel and seeds. The separated pure sea buckthorn pulp is discharged from the juice outlet into the first pulp storage tank 5 for storage. The mixture of peel and seeds is transported from the residue outlet to the first sugar washing tank 6. At the same time, high-temperature hot water can be added into the first sugar washing tank 6 through the first water inlet to provide the medium conditions for the subsequent sugar dissolving process.

[0022] Specifically, the low-temperature dual-stage pulping structure avoids the problems of nutrient loss and material deterioration caused by traditional high-temperature processing of sea buckthorn. At the same time, it achieves preliminary and efficient separation of fruit pulp and skin and seeds, greatly reducing the workload of subsequent sorting equipment, ensuring the quality of primary fruit pulp, and laying the foundation for subsequent sugar extraction and fine separation of skin and seeds.

[0023] Specifically, the sugar-dissolving pressing assembly includes a screw press 7, with the feed end of the screw press 7 connected to a second screw pump 8, and the other end of the second screw pump 8 connected to a first sugar washing tank 6; the juice outlet of the screw press 7 is connected to a second fruit pulp temporary storage tank 9; and the residue outlet is connected to a dispersion tank 10. The top of the dispersion tank 10 is provided with a second water inlet for adding high-temperature hot water.

[0024] Specifically, the mixture of peel and seed entering the first sugar washing tank 6 is mixed with high-temperature hot water in a 1:1 ratio and stirred thoroughly to fully dissolve the fructose and soluble sugars encapsulated in the peel tissue into the hot water, forming a sugary mixture. The fully dissolved material is then transported to the screw press 7 via the second screw pump 8, where the sugary hot water is thoroughly pressed and separated through physical extrusion. The pressed sugary juice is discharged into the second pulp storage tank 9 for centralized collection, while the completely sugar-free dry peel and seed residue is sent to the dispersion tank 10 through the residue outlet. At the same time, high-temperature hot water can be added into the dispersion tank 10 through the second water inlet to meet the ratio requirements for peel and seed dispersion and separation.

[0025] Specifically, by combining high-temperature hot water sugar dissolution with spiral physical pressing, the soluble sugars remaining in the peel are completely extracted, solving the problems of low sugar recovery rate and high sugar content in peel and seed residue in traditional processes. This greatly improves the comprehensive utilization rate of sea buckthorn raw materials. At the same time, the peel and seed material after pressing and dehydration is drier and looser, which facilitates subsequent peel and seed separation and sorting.

[0026] Specifically, the mixing and dispersing assembly includes a first cyclone separator 11, the feed end of the first cyclone separator 11 is connected to a third screw pump 12, and the other end of the third screw pump 12 is connected to a dispersion tank 10; the juice outlet of the first cyclone separator 11 is connected to a third temporary storage tank 13; and the slag outlet is connected to a first seed collection tank 14.

[0027] Specifically, the dry peel and seed residue entering the dispersion tank 10 is mixed with high-temperature hot water at a ratio of 1:5. The high-speed stirring structure at the bottom of the dispersion tank 10 is used to strongly disperse and stir the material, completely breaking the adhesion between the peel and the seeds, so that the seeds adhering to the inside of the peel are completely detached, forming a uniform mixture of peel, water, and seeds. The mixture is then transported to the first cyclone separator 11 by the third screw pump 12. The centrifugal separation principle is used to achieve preliminary solid-liquid separation. The separated seeds are discharged from the residue outlet into the first seed collection tank 14 for collection, while the peel-containing water material flows into the third temporary storage tank 13 from the juice outlet for temporary storage, awaiting secondary fine separation.

[0028] Specifically, by using high-speed hydraulic stirring and dissociation, the industry pain points of incomplete separation of peel and seed in traditional processes are completely solved. The peel and seed bond is broken up from a physical level, and combined with primary cyclone sorting, the seeds are initially recovered, which greatly improves the seed recovery rate and reduces the material handling pressure in subsequent processes.

[0029] Specifically, the multi-stage sorting and filtration assembly includes a second cyclone separator 15, the feed end of which is connected to a fourth screw pump 16, and the other end of the fourth screw pump 16 is connected to a third temporary storage tank 13; the slag outlet of the second cyclone separator 15 is connected to a second seed collection tank 17.

[0030] Specifically, the multi-stage sorting and filtering assembly also includes a scraper refiner 18, the feed end of which is connected to the juice outlet of the second cyclone separator 15, the slag outlet of which is connected to the colloid mill 19, and the discharge outlet of the colloid mill 19 is connected to the collection tank 2.

[0031] Specifically, the mixture of peel and water inside the third temporary storage tank 13 is transported to the second cyclone separator 15 by the fourth screw pump 16 for secondary fine centrifugal separation, further screening out residual small seeds. The separated seeds are discharged into the second seed collection tank 17 for centralized collection. The pure peel and water mixture after the seeds are completely removed is sent to the scraper refiner 18. Through the precision filtration and screening of the scraper refiner 18, the solid sea buckthorn peel is completely separated from the water. The filtered and purified peel is sent into the colloid mill 19 for ultra-fine grinding, grinding the peel into a fine and uniform sea buckthorn peel pulp. Finally, the ground peel pulp is discharged into the collection tank 2 for collection.

[0032] Specifically, a multi-stage combined process of two-stage cyclone separation, scraper filtration, and colloid mill grinding is adopted to achieve secondary fine separation of seeds, precise filtration of peels, and refined pulping, completely eliminating the mixing of peels and seeds, effectively improving the purity of the finished seed product and the fineness and quality of the sea buckthorn peel pulp, and realizing the refined deep processing of sea buckthorn by-products.

[0033] This device adopts an integrated continuous operation process of low-temperature pretreatment, sugar extraction, hydraulic dissociation, and multi-stage sorting. During operation, the impurity-removed sea buckthorn fruits are fed from the feed hopper 1 to the double-stage cold pulper 3 via the first screw pump 4 to complete low-temperature pulping, initially separating the fruit pulp from the mixture of peel and seeds. The mixture of peel and seeds enters the first sugar washing tank 6, where the sugar in the peel is dissolved by stirring with high-temperature hot water. Then, the sugar-containing juice is recovered by pressing with a screw press 7. The peel and seed residue after sugar removal is sent to the dispersion tank 10, where it is dispersed by high-temperature hot water and high-speed stirring. The dispersed peel, water, and seed mixture is then centrifuged in two stages by the first cyclone separator 11 and the second cyclone separator 15 to recover all the seeds step by step. The separated peel and water mixture is precisely filtered by the scraper refiner 18 to separate the peel. Finally, the peel is ground into a pulp by the colloid mill 19 and collected. The entire set of equipment is connected in series and works together to continuously complete the entire process of sea buckthorn fruit pulping, sugar extraction, peel and seed separation, multi-stage sorting, and peel pulping.

[0034] This seabuckthorn peel and seed separation device adopts an integrated process of low-temperature cold pressing, high-temperature sugar dissolving and pressing, high-speed stirring and dissociation, two-stage cyclone separation, and fine filtration pulping, which can achieve efficient separation and comprehensive utilization of seabuckthorn peel, seeds, and sugar. The separation rate of seabuckthorn fruit and seeds in this device can reach 99.8%, effectively solving the problems of fruit and seed embedding, incomplete sorting, and high loss in traditional processes. The obtained fruit and seeds have high purity and can be directly used for deep processing, significantly improving product quality and recovery rate.

[0035] Meanwhile, this device can fully utilize the sea buckthorn peel. After separation and purification, the peel is ground into a fine pulp using a colloid mill, preserving the active ingredients and avoiding waste. Furthermore, by combining high-temperature hot water sugar dissolution with pressing, soluble sugars in the residual pulp and peel of sea buckthorn can be thoroughly extracted, resulting in high sugar extraction and recovery rates. The entire device achieves comprehensive recycling of sea buckthorn seeds, peel, and sugars, with high raw material utilization and no significant material waste, effectively increasing the overall added value of sea buckthorn processing and making it suitable for industrialized, efficient, and refined production.
