Abstract
Description
Technical Field
[0001] This utility model relates to a kiwifruit peel and pulp separation device. Background Technology
[0002] In the kiwifruit processing industry, peel and pulp separation is a crucial step, and belt juicers are widely used due to their high efficiency. Belt juicers utilize two synchronously rotating mesh belts to progressively compress the kiwifruit, thus achieving peel and pulp separation. Using this equipment to process kiwifruit pulp typically yields a yield of over 87%, with the processed pulp particles ranging from 2.5 to 4.5 mm in size. For highly ripe kiwifruit, the yield is even higher, and the quality is more stable, ensuring the processed product has a sugar content between 15 and 18 Birx.
[0003] However, the cleaning of the conveyor belt in the actual operation of belt juicers has always been a problem for industry practitioners. Existing cleaning methods mainly involve scraping, such as the method used in patent "CN220712795U, A Belt Juicer for Fruit Juice Extraction". This cleaning method has many drawbacks: First, the scraper directly rubs against the conveyor belt, which easily damages the belt during long-term use, significantly shortening its lifespan and increasing equipment maintenance costs and downtime. Second, the scraper cannot effectively remove residual fruit pulp or peel from the mesh of the conveyor belt. Over time, these residues accumulate, not only affecting the belt's air permeability and reducing pressing efficiency, but also potentially breeding bacteria, seriously impacting the quality of the kiwi fruit pulp and causing a decline in its taste, color, and hygiene indicators.
[0004] In addition, some cleaning methods employ spray rinsing, but due to the lack of a targeted cleaning structure, the sprayed water cannot penetrate deep into the mesh of the conveyor belt, resulting in unsatisfactory cleaning effects. Moreover, the large volume of sprayed water used leads to water waste and increases the cost of subsequent wastewater treatment. Therefore, developing a kiwifruit peel and pulp separation device that can effectively solve the above problems has become an important issue that urgently needs to be addressed in this field. Utility Model Content
[0005] The purpose of this invention is to provide a kiwifruit peel and pulp separation device to solve the problems of easy damage to the mesh belt and incomplete cleaning of the mesh belt in existing juicers.
[0006] To solve the above problems, the technical solution of this utility model is as follows:
[0007] A kiwifruit peel and pulp separation device includes a belt juicer. The belt juicer includes a frame with two synchronously rotating mesh belts mounted on it. Two cleaning devices are mounted on the frame for brushing the mesh belts. Each cleaning device includes a cleaning tank with an inlet and an outlet at each end. Multiple overflow pipes are connected to the upper end of the cleaning tank, and a water inlet pipe is connected to the tank. Two first guide rollers are provided inside the cleaning tank. The mesh belts pass through the inlet and outlet and overlap the first guide rollers. A brushing mechanism is provided between the two first guide rollers. The brushing mechanism includes multiple brush rollers arranged sequentially inside the cleaning tank. Each brush roller has multiple grooves. A set of brush belts is connected between two adjacent brush rollers. Each set of brush belts includes multiple brush belts, each brush belt is fitted into the groove, and the brush belts are staggered between adjacent sets. Each brush belt is in contact with the surface of the mesh belt. One of the brush rollers is connected to a motor mounted outside the cleaning tank.
[0008] Furthermore, each cleaning box is equipped with two sets of brushing mechanisms, which are used to brush both sides of the conveyor belt.
[0009] Furthermore, it also includes a filter cake box, a water distributor, and multiple branch pipes. The filter cake box is equipped with a filter screen and a water pump. The branch pipes and the water distributor are located in the cleaning tank. Each branch pipe is connected to each outlet of the water distributor. One end of the inlet pipe is connected to the inlet of the water distributor, and the other end passes through the filter screen and is connected to the water pump. The upper end of the filter cake box is connected to the overflow pipe, and multiple spray pipes are connected to the branch pipes.
[0010] Furthermore, an ejector is installed on the water inlet pipe.
[0011] Furthermore, each nozzle is located between two adjacent brush belts, with the nozzle spraying downwards towards the mesh belt.
[0012] Furthermore, the upper end of the cleaning tank is connected to a drip tank, and a second guide roller is provided inside the drip tank. The belt outlet is located on one side of the drip tank, and the mesh belt overlaps the second guide roller.
[0013] Furthermore, two air knives are installed on one side of the belt outlet, with the air outlet direction of the two air knives tilted towards the front and back of the mesh belt respectively, and a mist exhaust pipe is installed on the drip box.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. Highly efficient cleaning, thorough scrubbing: This invention utilizes multiple brush rollers within the cleaning tank, with staggered brush belts connecting adjacent rollers. These brush belts then perform comprehensive scrubbing of the conveyor belt in water. The flexible bristles of the brush belts penetrate deep into the mesh of the conveyor belt during the scrubbing motion, thoroughly removing or breaking down fruit peels and pulp adhering to the belt, achieving thorough cleaning of the conveyor belt without any blind spots.
[0016] 2. Protects the conveyor belt and extends its service life: Unlike the traditional scraper dry grinding cleaning method, the brush belt used in this device is made of soft and elastic material, which will not cause hard damage to the conveyor belt during the brushing process, greatly reducing the maintenance cost and replacement frequency of the equipment, and improving the continuity and stability of production.
[0017] 3. Assisted rinsing for enhanced cleaning: An jet sprayer is installed on the water inlet pipe, and multiple nozzles are connected to the branch pipes. These nozzles are positioned between adjacent brush belts and spray downwards onto the mesh belt. During the brushing process, the water bubbles sprayed from the jet sprayer provide auxiliary rinsing to the mesh belt. As these bubbles pass through the gaps between the brush belts, they directly impact the surface of the mesh belt, quickly carrying away the scrubbed fruit pulp and peel, further improving the cleaning effect.
[0018] 4. Water recycling and resource conservation: This device is equipped with a filter cake box, filter screen, and water pump. Water used to wash the mesh belt, carrying fruit peels and pulp, flows through the overflow pipe into the filter cake box. After being filtered by the filter screen, it is pumped back for reuse. This design ensures full utilization of water resources. Compared to traditional single-use rinsing methods, water consumption is reduced, effectively conserving water resources. Simultaneously, it reduces wastewater discharge, lowers wastewater treatment costs, and meets environmental protection requirements.
[0019] 5. Drying the mesh belt to ensure pulp quality: A drip tank is connected to the top of the washing box, and two air knives are installed on one side of the belt outlet. The air knives are angled towards both sides of the mesh belt at an angle of 15°~30° to the belt surface. A mist exhaust pipe is also installed on the drip tank. After washing, the mesh belt is initially dripped with water in the drip tank. Then, the planar air blown by the air knives sweeps away the water droplets on the mesh belt surface, atomizing them and expelling them through the mist exhaust pipe. This ensures the mesh belt enters the next pressing process in a dry state. This effectively avoids the problem of quality degradation caused by the addition of washing water to the pressed kiwi pulp, ensuring the pulp's taste, sweetness, and stability.

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figures 1 to 5 As shown, a kiwifruit peel and pulp separation device includes a belt juicer. The belt juicer includes a frame with two synchronously rotating mesh belts 10 mounted on it. Two cleaning devices are installed on the frame to wash the two mesh belts 10. Each cleaning device includes a cleaning tank 3 with an inlet and an outlet at each end. Two overflow pipes 1 are connected to the upper end of the cleaning tank 3, located on both sides of the mesh belts 10. A water inlet pipe 20 is connected to the cleaning tank 3. Two first guide rollers 2 are installed inside the cleaning tank 3. The mesh belts 10 pass through the inlet and outlet. The mesh belt 10 is fed onto the first guide roller 2, which is used to guide the mesh belt 10 into the water. A brushing mechanism is provided between the two first guide rollers 2. The brushing mechanism includes three brush rollers 11 arranged in sequence in the cleaning tank 3. Multiple grooves are provided on the brush rollers 11. A set of brush belts 4 is connected between two adjacent brush rollers 11. Each set of brush belts 4 includes multiple brush belts 4. Each brush belt 4 is assembled in the groove. The two adjacent sets of brush belts 4 are staggered. Each brush belt 4 is in contact with the surface of the mesh belt 10. One of the brush rollers 11 is connected to a motor 18 installed outside the cleaning tank 3.
[0029] During implementation, the belt juicer continuously separates the kiwifruit peel from the pulp. Some of the separated pulp and peel adhere to the belt press's mesh belt 10. As the mesh belt 10 continues to rotate, the two mesh belts 10 enter two separate cleaning devices, where they are scrubbed. The cleaning device operates as follows: water is continuously poured into the cleaning tank 3 through the inlet pipe 20, and then discharged through the overflow pipe 1, ensuring that the water submerges the brush belt 4 and the mesh belt 10. Simultaneously, the motor 18 drives... Two sets of brush belts 4 rotate in the opposite direction to the mesh belt 10. The brush belts 4 are used to brush the pulp and peel adhering to the mesh belt 10. The pulp and peel washed off are discharged from the overflow pipe 1 with the continuous flow of water. Since the bristles in the brush belts 4 can enter the mesh of the mesh belt 10 during brushing, the pulp and peel in the mesh can be cleaned. In addition, compared with the scraper and spatula mesh belt 10, the elastic bristles will not damage the mesh belt 10 and can also achieve a good cleaning effect.
[0030] Each cleaning tank 3 is equipped with two sets of brushing mechanisms, which are used to brush both sides of the mesh belt 10. The two sets of brushing mechanisms brush both sides of the mesh belt 10 simultaneously, improving the cleaning effect of the mesh belt 10.
[0031] like Figures 1 to 3 As shown, it also includes a filter cake box 14, an inlet pipe, a distributor 19, and multiple branch pipes 12. The filter cake box 14 contains a filter screen 16 and a water pump 15. The branch pipes 12 and the distributor 19 are located inside the cleaning tank 3. The distributor 19 has one inlet and multiple outlets. One end of the branch pipe 12 is closed, and the other end is connected to each outlet of the distributor 19. One end of the inlet pipe is connected to the inlet of the distributor 19, and the other end passes through the filter screen 16 and connects to the water pump 15. The upper end of the filter cake box 14 is connected to the overflow pipe 1. Multiple spray pipes 17 are connected to the branch pipes 12. A jet injector 13 is installed on the inlet pipe. Each spray pipe 17 is located between two adjacent brush belts 4, and the spray direction of the spray pipe 17 is downward towards the mesh belt 10.
[0032] During implementation, the water pump 15 continuously draws clean water from the filter cake box 14 and sprays it out from each nozzle 17 through the jet injector 13. The bulging water bubbles pass through the gap between the two adjacent brush belts 4 and directly impact the mesh belt 10. Under the scrubbing of the brush belts 4, the fruit peels and pulp adhering to the mesh belt 10 are quickly removed, improving the cleaning efficiency of the mesh belt 10. After cleaning, the water carrying the fruit peels and pulp is discharged into the filter cake box 14 through the overflow pipe 1. The water entering the filter cake box 14 is filtered by the filter screen 16 and then pumped out by the water pump 15 for recycling, avoiding water waste.
[0033] The upper end of the washing tank 3 is connected to the drip tank 6, and the drip tank 6 is equipped with a second guide roller 9. The belt outlet is located on one side of the drip tank 6, and the mesh belt 10 overlaps the second guide roller 9. There are some water droplets adhering to the mesh belt 10 after it has just been washed. The drip tank 6 is set up to allow the mesh belt 10 to drip water before pressing the kiwi fruit.
[0034] like Figure 1 and 4 As shown, two air knives 8 are provided on one side of the conveyor belt outlet. The air outlet directions of the two air knives 8 are inclined towards the front and back sides of the conveyor belt 10, respectively, with the angle between the air outlet direction of the air knives and the surface of the conveyor belt 10 being 15° to 30°, and the inclined direction facing the outlet. The air knives 8 are connected to the air pump (not shown in the diagram). A mist exhaust pipe 7 is provided on the drip tank 6, which is connected to the exhaust fan (not shown in the diagram). After the conveyor belt 10 exits from the outlet, the planar air blown by the air knives 8 sweeps away the water droplets on the surface of the conveyor belt 10, causing the water droplets to atomize and return to the drip tank 6 and be discharged from the mist exhaust pipe 7. This ensures that the conveyor belt 10 is in a dry state when pressing the kiwifruit, preventing the kiwifruit pulp from being mixed with washing water, which would affect the quality of the pulp.
[0035] The brush belt has soft and elastic nylon bristles with a length of 10-20mm to clean the mesh without damaging it.
[0036] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
