Description

Technical Field

[0001] This invention relates to the field of food processing technology, and more specifically, to a plum juice and a raw material screening device for processing it. Background Technology

[0002] As a traditional summer drink, plum juice has seen a surge in market demand due to the rise of healthy eating trends, especially among young consumers. The purity of its raw materials directly determines the product quality and taste, making efficient and precise screening technology a core element of industrial production.

[0003] As one of the main ingredients of sour plum soup, dried plums usually need to be screened to remove impurities. Among them, the air separation device is more effective in the primary purification stage of raw materials due to its non-contact separation, high efficiency and low consumption. It is especially suitable for the rapid pretreatment of large-scale raw materials and can maintain the integrity of the raw materials to the greatest extent.

[0004] Although dried plums have obvious advantages in transportation and storage, this also makes them more susceptible to moisture during transportation and long-term storage, which leads to deeper wrinkles. This makes it easy for non-edible impurities such as fruit stems, calyxes, and insect fragments that are already present in the dried plums during centralized storage to become embedded in the wrinkles of the outer skin and flesh during transportation. Existing raw material air separation and screening devices are unable to cope with the particle shape of these deeply embedded impurities, and therefore cannot completely separate these embedded impurities, resulting in a decrease in the effective interception rate and affecting the final screening effect.

[0005] Therefore, this application proposes a plum juice and a raw material screening device for its processing to solve the above problems. Summary of the Invention

[0006] Technical problem to be solved: In view of the problems existing in the prior art, the purpose of this invention is to provide a plum juice and raw material screening device for processing, which solves the problem that the existing raw material air separation screening device is difficult to separate dried plums due to moisture and wrinkles during transportation and storage, resulting in residual non-edible impurities embedded in the fruit pulp wrinkles and causing low screening efficiency.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a plum juice, comprising the following ingredients in parts by weight: 10-20 parts dried plums, 50-80 parts water, 5-15 parts white sugar, 3-10 parts honey, 1-5 parts cordyceps militaris, 1-5 parts chrysanthemum and Panax notoginseng, and 1-4 parts additives.

[0011] In a new embodiment, the top of the air spray chamber is provided with multiple exhaust strips at equal intervals, and a rubber strip is provided between adjacent exhaust strips. The rubber strip is installed on the top of the air spray chamber. A cooling strip is installed on the inner wall of the bottom air inlet of the air spray chamber located on the outer side of the top of the inclined plate, and a heating resistance wire is installed on the inner wall of the bottom air inlet of the air spray chamber located on the inner side of the top of the inclined plate. The bottom air inlets of the air spray chamber are all connected to the embedded pipe inside the inclined plate, and the air inlet of the embedded pipe is located at the bottom of the inclined plate.

[0012] In a new embodiment, a telescopic plate is also installed at the rear bottom of the inclined drop plate. The telescopic plate slides within a locking plate, which is installed on the top of the base box. The bottom end of the telescopic plate is connected to the bottom wall of the top groove of the locking plate by a plurality of equally spaced reset springs.

[0013] In a new embodiment, the feeding assembly includes: a feeding box, installed on the top of the screening box, with a funnel-shaped material outlet at the bottom center of the feeding box; and a discharge rod, rotatably installed in the lower middle part of the feeding box, located in the middle of the funnel-shaped material outlet; the discharge rod has multiple flexible protrusions installed in a ring at equal intervals on its outer side, and one end of the discharge rod is fixedly connected to the output end of a drive motor fixedly installed in the front middle part of the screening box.

[0014] In a new embodiment, the impact assembly includes: two convex shafts, which are rotatably mounted on the top left and right sides of the base box, respectively, and the convex shafts are located below the contact plate; a drive wheel is fixedly mounted on the front end of one of the convex shafts, and a driven wheel is fixedly mounted on the front end of the other convex shaft, with the drive wheel connected to the driven wheel via a belt; and a servo motor, which is mounted on the top front side of the base box, and whose output end is fixedly connected to the front end of the drive wheel.

[0015] In a new embodiment, the air circulation assembly includes: a second exhaust hood, which is installed on the left and right inner walls of the base box respectively; a three-ventilation duct, which is located in the middle of the base box; the two straight openings of the three-ventilation duct are connected to the second exhaust hood facing the corresponding direction, the side interface of the three-ventilation duct passes through the rear wall of the screening box and is connected to the exhaust duct at one end, and the other end of the exhaust duct is connected to the exhaust port of the wind-gathering hood; and a top-through telescopic pipe, which is installed on the left and right sides of the top of the horizontal pipe of the three-ventilation duct, and the top end is connected to the air inlet of the embedded pipe located at the bottom of the inclined plate.

[0016] In a new embodiment, a receiving box is provided on the lower left and right sides of the screening box, an outer shell is installed on the left and right sides of the screening box, an impurity box is provided at the bottom of the outer shell, and an impurity discharge port is opened in the lower middle part of the inner wall of the left and right sides of the screening box, and an inclined baffle is installed in the impurity discharge port.

[0017] Beneficial effects: Compared with the prior art, the advantages of the present invention are: 1. By setting the ratio of raw materials such as dried plum, Cordyceps militaris, Panax notoginseng and packaging materials, a compound system of plum base and food-medicine homologous ingredients is formed, which gives plum soup a compound health care effect such as anti-oxidation, anti-fatigue and metabolism regulation, and has both traditional flavor and modern health care function.

[0018] 2. The feeding component forms a gear volume cavity with the funnel opening through the flexible protrusions. The drive motor adjusts the speed to achieve quantitative feeding of dried plums, avoiding uneven feeding or blockage. The flexible protrusions elastically adapt to the shape of the dried plums, eliminating rigid extrusion damage and ensuring that the raw materials are fed in an intact and uniform manner.

[0019] 4. The intermittent impact of the convex shaft on the contact plate drives the inclined drop plate to swing. The telescopic plate and the return spring limit the swing range and assist in the return, forming a regular vibration and throwing process to ensure that the dried plums are subjected to the throwing impact treatment, so that the impurities in the folds of the dried plum skin and flesh are removed and peeled off.

[0020] 3. The system utilizes a zoned output of hot air from the air-spray chamber to soften wrinkles, ambient air to prevent sticking and cool down, and cold air to harden and shape the dried plums. Combined with the periodic oscillation of the inclined drop plate, the dried plums collide with the surface of the flexible material barrier plate. This causes embedded impurities to quickly loosen and detach from the fruit peel under the dual effects of impact and thermal softening. This solves the problem of impurities embedded in the wrinkles of the dried plum peel and flesh being unable to be effectively separated, thus improving the screening effect.

[0021] 5. The exhaust gas from the first row of air hoods is recovered through the air circulation component, and after treatment, it supplies air to the air spray chamber and the second row of air hoods, realizing energy recycling. Combined with multi-stage screening of transverse air separation, temperature field stripping and end air separation, impurities are efficiently separated and the quality of dried plum collection is guaranteed.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] This application provides a raw material screening device for plum juice and its processing, which solves the problem that existing raw material air separation screening devices are difficult to separate dried plums due to moisture and wrinkles during transportation and storage, resulting in residual non-edible impurities embedded in the fruit pulp wrinkles and causing low screening efficiency. In use, the device utilizes the air spray chamber to output hot, normal temperature and cold air in different areas to form a gradient temperature field. Combined with the oscillation of the inclined drop plate and the collision of the flexible barrier plate, it can achieve deep peeling and screening of impurities in the fruit pulp wrinkles of the dried plum.

[0035] The technical solutions in this application are intended to solve the above-mentioned technical problems, and the overall approach is as follows.

[0036] Example 1: This example provides a sour plum drink, comprising the following ingredients by weight: 10-20 parts dried plums, 50-80 parts water, 5-15 parts white sugar, 3-10 parts honey, 1-5 parts cordyceps militaris, 1-5 parts chrysanthemum and Panax notoginseng, and 1-4 parts supplementary ingredients.

[0037] Furthermore, the additives include the following components by weight: 1-2 parts chicory root extract, 0.5-1 part turmeric powder, and 0.3-0.8 parts rosemary extract; the chicory root extract is an aqueous extract with an inulin content ≥60%, and the rosemary extract is an ethanolic extract with a rosmarinic acid content ≥20%.

[0038] Dried plums, as the core flavor source of sour plum drink, provide its unique sweet and sour taste. They are rich in fruit acids (such as citric acid), which can stimulate saliva secretion, quench thirst, and promote digestion. Water, white sugar, and honey provide the necessary sugars and neutralize the sourness. Cordyceps militaris is rich in cordycepin, cordyceps polysaccharides, amino acids, etc., which can enhance immunity and fight fatigue. Panax notoginseng contains active ingredients such as flavonoids and saponins, which have the effects of clearing heat and detoxifying, cooling blood and stopping bleeding. It can neutralize the acidity of dried plums and balance the properties of the drink.

[0039] Chicory root extract is a water-soluble dietary fiber that can promote the proliferation of beneficial bacteria in the gut, improve the gut microbiota, and relieve constipation; turmeric powder contains curcumin, which has significant anti-inflammatory effects, can reduce chronic inflammatory responses in the body, and at the same time scavenge free radicals, enhancing the antioxidant activity of beverages; the herbal aroma of rosemary extract can subtly enhance the flavor profile of beverages, creating a complex taste with plum and honey.

[0040] In summary, by introducing medicinal and edible ingredients such as Cordyceps militaris and Panax notoginseng into plum juice, a formula type combining plum base and functional components is formed. Cordyceps militaris is rich in cordycepin and polysaccharides, while Panax notoginseng contains flavonoids. When combined with dried plums, honey, and other ingredients, plum juice can be endowed with compound health benefits such as antioxidant, anti-fatigue, and metabolism-regulating effects, breaking through the limitations of traditional plum juice which only quenches thirst and relieves summer heat, and meeting the needs of modern consumers for functional beverages.

[0041] Example 2, please refer to Figures 1-10This embodiment also provides a raw material screening device for processing plum juice, used to screen dried plums in a plum juice, including: a screening box 1; a feeding component 2, installed on the top of the screening box 1, used for quantitative discharge of dried plums; two inner wall boxes 3, respectively installed on the upper part of the left and right inner walls of the screening box 1; a first exhaust hood 31 is installed in the middle of the inner side of one inner wall box 3, and an arc-shaped intercepting mesh 32 is installed in the middle of the inner side of the other inner wall box 3; a baffle plate 4 is installed at the bottom of the inner wall box 3, and the bottom end of the baffle plate 4 is bonded to... The system includes a flexible contact pad 41; a base box 5, which is a hollow structure and is installed in the middle of the screening box 1; a partition plate 6 is installed at the top center of the base box 5; inclined drop plates 7 are rotatably installed on the left and right sides of the top of the base box 5; three air spray chambers 8 are fixedly connected at equal intervals at the top of the inclined drop plates 7; a contact plate 9 is installed at the bottom center of the inclined drop plates 7; an impact assembly 13 is installed on the top of the base box 5 and is used to intermittently impact the contact plates 9 to drive the inclined drop plates 7 to swing; and an air circulation assembly 14 is installed in the middle of the base box 5 and is used to provide air source for the three air spray chambers 8.

[0042] By setting up a barrier plate 4, a flexible contact pad 41, a base box 5, a partition plate 6, an inclined drop plate 7, an air spray chamber 8, and a contact plate 9, when the dried plums enter the screening box 1 through the feeding component 2, they first undergo transverse air separation pretreatment by the first row of air hoods 31 and the arc-shaped intercepting net 32 ​​on the inner wall box 3. This pre-screens any broken materials or other impurities contained in the dried plums during transportation. The screened dried plums continue to fall and are diverted by the partition plate 6 to the inclined drop plates 7 on the left and right sides for further screening. The inclined drop plates 7 intermittently impact the contact plate 9 through the impact component 13, causing the dried plums to be thrown outwards and fly up to collide with the barrier plate 4 at the bottom of the inner wall box 3 (the flexible contact pad 41 at the bottom of the barrier plate 4 is made of silicone to prevent damage to the outer skin of the dried plums due to hard impact). At the same time, the air spray chamber 8... The circulation component 14 provides a staged temperature air field to the air spray chamber 8 on the inclined drop plate 7. The heating resistance wire 85 of the air spray chamber 8 on the top inner side of the inclined drop plate 7 comes into contact with the input air to generate hot air, which softens the skin of the dried plum (especially the wrinkles) in a shallow layer. The embedded impurities loosen due to softening and expansion, and are further removed under the impact. The central air spray chamber 8 is at room temperature, which maintains the initial softening state of the dried plum while cooling it to a certain extent, avoiding the sticking problem when the softened skin of the dried plum comes into contact with the inclined drop plate 7. The cooling strip 84 of the outer air spray chamber 8 comes into contact with the input air to generate cold air, which makes the softened skin firm again, avoiding the problem of external damage to the dried plum during the falling and collection stage. By using the dual effects of heating and softening and vibration and impact, combined with the gradual air treatment of cooling and hardening and the buffering effect of the flexible surface of the inclined drop plate 7, the impurities embedded in the wrinkles are forced to detach, while avoiding damage to the skin of the dried plum, thus solving the problem that traditional air separation is difficult to separate deep impurities.

[0043] Please see Figure 1 , Figure 2 and Figure 4 The feeding assembly 2 includes: a feeding box 201, which is installed on the top of the screening box 1, and a funnel-shaped material outlet 202 is provided at the bottom center of the feeding box 201; a discharge rod 203, which is rotatably installed in the lower middle part of the feeding box 201 and located in the middle of the funnel-shaped material outlet 202; a plurality of flexible protrusions 204 are equidistantly annularly installed on the outside of the discharge rod 203, and one end of the discharge rod 203 is fixedly connected to the output end of the drive motor 205 fixedly installed in the front middle part of the screening box 1.

[0044] By setting up a feeding box 201, a funnel-shaped material inlet 202, a discharge rod 203, flexible convex strips 204, and a drive motor 205, the flexible convex strips 204 distributed in a ring on the outside of the discharge rod 203 form a gear-like volume cavity structure with the inner wall of the funnel-shaped material inlet 202. When the drive motor 205 drives the discharge rod 203 to rotate, the gap between adjacent flexible convex strips 204 can receive dried plums quantitatively in a single batch. Precise feeding flow control can be achieved by adjusting the rotation speed, avoiding the uneven feeding or blockage problems caused by accumulation in traditional gravity feeding. This is suitable for the stable feeding needs in industrial continuous production scenarios. At the same time, when rotating and pushing the material, the flexible convex strips 204 adapt to the irregular shape of the dried plums through elastic deformation, avoiding damage to the fruit pulp or deepening of wrinkles caused by rigid compression. This ensures that the dried plums fall into the screening box 1 in an undamaged manner, providing a complete raw material base for the subsequent air separation process.

[0045] Please see Figure 3 An exhaust pump 33 is installed on the upper part of the left outer wall of the screening box 1. The exhaust port of the exhaust pump 33 is connected to the first exhaust hood 31 through a pipe. An air-gathering hood 34 is installed on the upper part of the right side of the screening box 1 and is connected to the right inner wall box 3.

[0046] By setting up an exhaust pump 33 and a wind-gathering hood 34, after the dried plums fall into the screening box 1, the exhaust pump 33 on the left generates a transverse airflow through the first row of wind hoods 31, and the curved intercepting net 32 ​​on the right cooperates to form an air separation channel. Light impurities (such as debris and dust) in the dried plums are blown by the airflow and adsorbed onto the curved intercepting net 32. Dried plums of moderate weight continue to fall to the inclined drop plate 7 below. This process achieves the screening of broken materials or impurities contained in the dried plums during transportation through transverse air screening. The wind-gathering hood 34 collects the air source discharged by the first row of wind hoods 31.

[0047] Please see Figure 5 A telescopic plate 10 is also installed at the rear of the bottom of the inclined plate 7. The telescopic plate 10 slides in the locking plate 11. The locking plate 11 is installed on the top of the base box 5. The bottom of the telescopic plate 10 is connected to the bottom wall of the top groove of the locking plate 11 by a plurality of equally spaced reset springs 12.

[0048] By setting up the inclined drop plate 7, the telescopic plate 10, the locking plate 11, and the return spring 12, when the impact assembly 13 intermittently impacts the contact plate 9, the telescopic plate 10 slides within the locking plate 11, which limits the swing range of the inclined drop plate 7 and prevents excessive swing from causing the dried plums to be thrown out of control. Combined with the elastic effect of the return spring 12, the inclined drop plate 7 returns to its original position smoothly after impact, forming a regular periodic swing, ensuring that the swing amplitude of the inclined drop plate 7 is stable and controllable, so that the dried plums can obtain a uniform vibration and throwing effect on the surface of the inclined drop plate 7, and improve the consistency of impurity stripping.

[0049] Please see Figures 8-10 The top of the air spray chamber 8 is provided with multiple exhaust strip ports 81 at equal intervals, and a rubber strip 82 is provided between adjacent exhaust strip ports 81. The rubber strip 82 is installed on the top of the air spray chamber 8. A cooling strip 84 is installed on the inner wall of the bottom air inlet 83 of the air spray chamber 8 located on the outer side of the top of the inclined plate 7, and a heating resistance wire 85 is installed on the inner wall of the bottom air inlet 83 of the air spray chamber 8 located on the inner side of the top of the inclined plate 7. The bottom air inlets 83 of the air spray chamber 8 are all connected to the internal embedded pipes 86 inside the inclined plate 7, and the air inlets of the internal embedded pipes 86 are located at the bottom of the inclined plate 7.

[0050] By setting up an air spray chamber 8, an exhaust outlet 81, a rubber strip 82, an air inlet 83, a cooling strip 84, a heating resistance wire 85, and an internal pipe 86, the air circulation component 14 is first connected to the internal pipe 86 to provide an air source for the air spray chamber 8. With different settings of the air spray chamber 8, a staged temperature air field is formed. The inner air spray chamber 8 generates hot air through the contact between the heating resistance wire 85 and the airflow, which softens the shallow layer of the dried plum's outer skin folds. The embedded impurities expand and loosen due to softening, and are further removed by the impact. The normal temperature air in the central air spray chamber 8 maintains the initial temperature of the dried plum. The softened outer skin is kept in a softened state while the surface temperature is reduced to prevent the softened outer skin from sticking to the flexible surface of the inclined drop plate 7. The outer air spray chamber 8 generates cold air through the contact of the airflow with the cooling strip 84, which quickly hardens the softened outer skin, restores its structural strength, and prevents it from being damaged when it falls for collection. Through the temperature gradient treatment of hot air softening, room temperature maintenance to prevent sticking, and cold air shaping, combined with the vibration impact generated by the swing of the inclined drop plate 7, the impurities and the embedded state of the dried plum folds are efficiently broken. At the same time, the rubber strip 82 protects the exhaust strip 81 to prevent the dried plum from directly contacting it and causing it to get stuck.

[0051] Please see Figure 5 and Figure 7The impact assembly 13 includes: two convex shafts 1301, which are rotatably mounted on the top left and right sides of the base box 5, and the convex shafts 1301 are located at the lower part of the contact plate 9; one convex shaft 1301 has a drive wheel 1302 fixedly mounted at its front end, and the other convex shaft 1301 has a driven wheel 1303 fixedly mounted at its front end, and the drive wheel 1302 is connected to the driven wheel 1303 by a belt; a servo motor 1304 is mounted on the top front side of the base box 5, and its output end is fixedly connected to the front end of the drive wheel 1302.

[0052] By setting up a convex shaft 1301, a drive wheel 1302, a driven wheel 1303, a belt, and a servo motor 1304, the servo motor 1304 drives the drive wheel 1302 to rotate, which in turn drives the driven wheel 1303 to rotate synchronously via the belt. This causes the convex shafts 1301 on both sides to rotate synchronously. The convex bars on the convex shaft 1301 intermittently impact the contact plate 9, thereby causing the inclined drop plate 7 to swing back and forth. This design allows the dried plums to vibrate and be thrown regularly on the surface of the inclined drop plate 7. Combined with the flexible collision of the barrier plate 4 and the temperature gradient effect of the air spray chamber 8, it achieves the dual effects of mechanical vibration peeling and thermal phase change loosening, effectively forcing impurities embedded in the folds of the dried plums to detach.

[0053] Please see Figure 2 and Figure 5 The air circulation assembly 14 includes: a second exhaust hood 1401, which is installed on the left and right inner walls of the base box 5 respectively; a three-ventilation pipe 1402, which is located in the middle of the base box 5; the two straight ports of the three-ventilation pipe 1402 are connected to the second exhaust hood 1401 in the corresponding direction, the side interface of the three-ventilation pipe 1402 passes through the rear wall of the screening box 1 and is connected to one end of the exhaust pipe 1403, and the other end of the exhaust pipe 1403 is connected to the exhaust port of the wind concentrator hood 34; and a top-through telescopic pipe 1404, which is installed on the left and right sides of the top of the horizontal pipe of the three-ventilation pipe 1402, and the top end is connected to the air inlet 83 of the embedded pipe 86 located at the bottom of the inclined plate 7.

[0054] By setting up a second exhaust hood 1401, a three-way ventilation duct 1402, an exhaust duct 1403, and a top-through telescopic pipe 1404, the airflow discharged from the wind-gathering hood 34 is input to the second exhaust hood 1401 through the exhaust duct 1403 and the three-way ventilation duct 1402, providing a wind selection source for subsequently falling embedded impurities. In addition, the top-through telescopic pipe 1404 connected by the three-way ventilation duct 1402 also provides a wind source for the air spray chamber 8 on the inclined drop plate 7. It should be noted that the top-through telescopic pipe 1404 will not affect the swing of the inclined drop plate 7. It should also be noted that the wind-gathering hood 34 has an impurity filtration effect.

[0055] Please see Figure 3The screening box 1 is provided with a receiving box 15 on the lower left and right sides. The screening box 1 is provided with an outer shell 16 on the left and right sides. The bottom of the outer shell 16 is provided with an impurity box 17. The lower middle part of the inner wall of the left and right sides of the screening box 1 is provided with an impurity discharge port 18. An inclined baffle 19 is installed in the impurity discharge port 18.

[0056] By setting up a receiving box 15, an outer shell 16, an impurity box 17, an impurity discharge port 18, and an inclined baffle 19, the sieved dried plums roll down along the inclined drop plate 7. After being separated by the air separation effect of the second row of air hoods 1401, the detached impurities (i.e., impurities embedded in the folds of the outer skin and pulp) fall into the impurity box 17 through the inclined blocking effect of the impurity discharge port 18 and the inclined baffle 19. Meanwhile, the dried plums with heavy weight fall into the receiving box 15 at the bottom of the screening box 1, thus completing the collection of the processed dried plums.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
