Description

Technical Field

[0001] This utility model belongs to the field of bayberry processing technology, specifically relating to a wet bayberry pulp separation device. Background Technology

[0002] The waxberry (Myrica rubra), a high-value fruit unique to my country, is highly favored by consumers for its distinctive flavor and rich nutrition, leading to a continuous increase in market demand for its processed products (such as juice, jam, and wine). However, the large-scale development of the waxberry processing industry has long been constrained by technological bottlenecks in the pulp separation process.

[0003] The unique structure of the bayberry fruit, with its soft, delicate, and juicy flesh, contrasts sharply with its hard, irregularly shaped pit that is tightly adhered to the flesh.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0018] To address the challenge of existing technologies and equipment failing to achieve efficient, high-yield, and pit-free pulp separation while preserving the natural texture and color of the fruit, this invention provides a wet-process bayberry pulp separation device. This device sequentially performs a combined cleaning process using bubbles and water flow, differentiated pulping based on different crushing mechanisms, and finally, fine separation of the pulp and pit through a combination of flexible extrusion and vibrating screening. This significantly reduces the risk of the pit being broken by rigid impact during separation, thus fundamentally eliminating pit contamination of the pulp and ensuring the safety and purity of the final product's flavor. In this process, extrusion rollers made of microporous material with integrated circulating water channels rotate in opposite directions, gently extruding the material. Simultaneously, directional low-pressure airflow blows across the peeling surface, and a high-frequency micro-vibrating scraper cleans the surface. This synergistic effect maximizes the preservation of the original shape and nutritional components of the pulp. The unique dual-axis design of the pulping module, combined with a mode-switching mechanism, allows for the sequential completion of coarse and fine pulping processes within the same chamber. This not only improves the yield of intact fruit pulp but also optimizes production efficiency. The entire separation process is seamless and automated, with each functional module connected via specific interfaces and channels. This reduces the need for manual intervention, improves hygiene conditions, and provides reliable technical support for the large-scale, standardized deep processing of bayberries.

[0019] The present invention provides a detailed description of a wet-type bayberry pulp separation device in conjunction with the accompanying drawings.

[0020] Figure 1 This is a simplified diagram of a wet-type bayberry pulp separation device provided in an embodiment of this utility model. Figure 2 This is a simplified diagram of the bubble cleaning machine provided in this embodiment of the utility model. Figure 3 Figure 1 is a simplified diagram of the pulping machine provided in an embodiment of this utility model, and Figure 2 is a simplified diagram of the pit and pulp separator provided in an embodiment of this utility model. Figure 1As shown, the device includes: a bubble washing machine 1, a pulping machine 2, and a pit and pulp separator 3; the bubble washing machine 1 is equipped with a bubble generating mechanism 11 and a water jetting mechanism 12 for washing bayberries; the pulping machine 2 includes a pulping chamber 21, a switchable dual pulping head module 22 partially disposed within the pulping chamber 21, and a screen disposed at the bottom of the pulping chamber 21; the upper part of the pulping chamber 21 is provided with an inlet 23, which is connected to the outlet of the bubble washing machine 1, and the lower part of the pulping chamber 21 is provided with a first outlet and a pit outlet 24; the first outlet is connected to a sterilizer, and the pit outlet 24 is connected to the sterilizer. The outlet 24 is connected to the inlet of the pit and meat separator 3; the pit and meat separator 3 includes a separation chamber 31, and a first roller 32 and a second roller 33 installed on the separation chamber 31; both the first roller 32 and the second roller 33 are provided with circulating water channels, which are connected to an inlet and an outlet; a low-pressure airflow nozzle is provided above the first roller 32 and the second roller 33; an ultrasonic vibration scraper 34 is provided on one side of the first roller 32, and a vibrating screen and a pulp collection box 35 are arranged in sequence below the separation chamber 31; the first roller 32 and the second roller 33 are connected by a drive and can rotate in opposite directions.

[0021] Here, as Figure 1-2As shown, the bubble generating mechanism 11 includes multiple ultrasonic bubble generators, which are evenly arranged at the bottom of the housing of the bubble cleaning machine 1. The water jet mechanism 12 includes several small holes, which are evenly arranged on the side wall of the housing of the bubble cleaning machine 1. In actual operation, a certain amount of water is first injected into the housing, and the bayberries to be cleaned are poured into it. Then, the bubble generating mechanism 11, i.e., the multiple ultrasonic generators located at the bottom of the housing, is activated. The ultrasonic transducers generate high-frequency vibrations (usually 20kHz-40kHz), forming alternating dense and sparse sound waves in the water. In the "sparse part" of the sound wave, water molecules are pulled apart, forming a large number of extremely fine microbubbles (cavitation bubbles). These microbubbles grow and expand rapidly under the action of the sound waves, and then collapse and rupture instantly in the "dense part". The instant the bubbles rupture, the strong local shock wave and high-speed micro-jet will be generated, which can effectively loosen and peel off the mud, pesticides, insects, microorganisms and other impurities attached to the surface of the bayberry. At the same time, the water jet mechanism 12 starts to work, and the high-pressure water pump sprays water through the small holes in the side wall of the box, forming multiple high-speed water jets. On the one hand, it provides a continuous flushing force for the bayberry, washing away the impurities that have been loosened. On the other hand, it ensures that the water and bayberries in the box are constantly tumbling, so that every surface of every bayberry can be cleaned evenly without any dead corners. In addition, because a large number of microbubbles are attached to the surface of the bayberry and impurities, their average density is reduced, generating a certain buoyancy effect, which helps the bayberry to tumble and the lighter impurities (such as leaves and insects) to float and separate. During the washing process, heavier impurities (such as mud and sand) that are removed will settle to the bottom of the tank and can be discharged periodically through the drain valve 15 at the bottom. Lighter floating impurities will be discharged with the water flow through the overflow outlet. The cleaned bayberries will be discharged from the discharge outlet 13 under the action of the water flow and enter the next pulping machine 2.

[0022] Here, in order to clearly see the sedimentation of impurities inside the box and the washing status of the bayberries, an observation window 1 is opened on one side of the box.

[0023] During the pulping process in the fruit pulping machine 2, the single grinding method easily crushes the hard fruit pits, causing pit fragments to mix into the pulp. Waxberry pits not only have a rough texture but also contain small amounts of undesirable components such as hydrocyanic acid. The inclusion of pit fragments severely affects the product's taste, color, and safety. To avoid this, a dual pulping head module 22 provides multiple grinding methods, allowing for adjustment according to actual needs.

[0024] like Figure 1 and 3As shown, the dual-head pulping module 22 includes: a drive device 221, a concentric dual-shaft structure, a coarse pulping component, and a fine pulping component; the concentric dual-shaft structure includes an independently rotating hollow outer shaft and a solid inner shaft, the solid inner shaft being sleeved inside the hollow outer shaft, and the lower end of the hollow outer shaft being connected to the coarse pulping component, and the lower end of the solid inner shaft passing through the hollow outer shaft and being connected to the fine pulping component; the drive device 221 is fixedly installed outside the pulping chamber and is provided with a mode switching mechanism for selectively transmitting power to the hollow outer shaft or the solid inner shaft, thereby realizing the switching between coarse pulping mode and fine pulping mode.

[0025] Specifically, the mode switching mechanism includes: a first electromagnetic clutch, a second electromagnetic clutch, and a transmission gear set; the transmission gear set includes a driving gear, a first driven gear, and a second driven gear; the driving gear meshes with both the first driven gear and the second driven gear simultaneously, and the first driven gear and the second driven gear have different gear ratios; the driving gear is fixedly mounted on the output shaft of the drive motor inside the drive device 221; the upper end of the hollow outer shaft is connected to the first driven gear through the first electromagnetic clutch; the upper end of the solid inner shaft is connected to the second driven gear through the second electromagnetic clutch.

[0026] In one possible implementation, the coarse crushing assembly includes a coarse crushing cutter disc connected to the hollow outer shaft, the coarse crushing cutter disc being provided with a plurality of blunt crushing blades; the fine crushing assembly includes a fine crushing cutter disc connected to the solid inner shaft, the fine crushing cutter disc being provided with a plurality of blade-shaped cutting blades.

[0027] It should be noted that the mesh size of the screen varies depending on the polishing method. For example, in the coarse polishing mode, the mesh size ranges from 5mm to 8mm; in the fine polishing mode, the mesh size ranges from 1mm to 2mm.

[0028] In actual operation, the drive device 221 includes a drive motor and a transmission box, with a mode switching mechanism inside the transmission box. The drive motor provides power, and its output shaft drives the drive gear to rotate. The drive gears mesh simultaneously, thus possessing different speed and torque characteristics (typically, the first driven gear is set to high speed and low torque for coarse grinding; the second driven gear is set to low speed and high torque for fine grinding). In coarse grinding mode, the control system energizes and engages the first electromagnetic clutch, while simultaneously de-energizing and disengaging the second electromagnetic clutch. Power is transmitted to the hollow outer shaft through the first driven gear and the first electromagnetic clutch, driving the coarse grinding assembly to rotate. At this time, the solid inner shaft and its fine grinding assembly do not rotate. In fine grinding mode, the control system energizes and engages the second electromagnetic clutch, while simultaneously de-energizing and disengaging the first electromagnetic clutch. Power is transmitted to the solid inner shaft through the second driven gear and the second electromagnetic clutch, driving the fine grinding assembly to rotate. At this time, the hollow outer shaft and its coarse grinding assembly do not rotate.

[0029] It should be noted that in the coarse crushing mode, high-speed rotating blunt-shaped crushing blades violently impact and compress the bayberries, quickly separating most of the pulp from the pits to form coarse pulp. This pulp is then rapidly discharged through a large-aperture screen and enters the sterilizer for pasteurization, greatly improving the production line's processing capacity. In the fine crushing mode, low-speed, high-torque rotating blades, like scrapers, finely scrape and cut the remaining pulp adhering to the pits, ensuring maximum pulp recovery and improving raw material utilization. The resulting fine pulp is also sent to the sterilizer for pasteurization.

[0030] After processing in pulping machine 2, some pulp will still remain on some fruit pits. In order to improve the pulp recovery rate, the residue (fruit pits and some pulp) in pulping machine 2 is sent to pit and pulp separator 3 for further processing.

[0031] It should be noted that both the first roller 32 and the second roller 33 are made of microporous food-grade silicone. Microporous food-grade silicone itself has excellent elasticity and flexibility. When the bayberry pits pass between the two opposing rotating rollers, the soft silicone roller surface undergoes slight deformation, thus adaptively wrapping around the irregularly shaped and varying-sized pits, increasing the effective contact area. Furthermore, even under continuous pressure, friction, and humid working conditions, it maintains its elasticity and the stability of its microporous structure, resulting in a long service life.

[0032] like Figure 1As shown in the diagram, specifically, a first support shaft 312 and a second support shaft 313 are fixedly mounted on the separation chamber 31 and arranged in parallel. The first roller 32 is rotatably sleeved on the first support shaft 312, and the second roller 33 is rotatably sleeved on the second support shaft 313. Both the first support shaft 312 and the second support shaft 313 have circulating water channels inside, with the inlets of the circulating water channels located at the ends of the first support shaft 312 and the second support shaft 313. Furthermore, the outlets of the circulating water channels are evenly distributed on the roller surfaces of the first roller 32 and the second roller 33.

[0033] It should be noted that a vibrating screen is essentially a screen plate or screen trough with fine mesh (screen), which can be elastically connected to the separation chamber 31 through a vibrating motor or eccentric wheel mechanism, enabling it to perform high-frequency, small-amplitude continuous vibration.

[0034] During operation, the counter-rotating microporous food-grade silicone rollers gently grasp and squeeze the fruit pits. The flexibility of the silicone ensures maximum contact with the irregular surface of the pits. Through continuous friction, residual pulp is efficiently removed. Cooling water in the circulating water system is transported through the support shaft and slowly seeps out from the micropores on the roller surface, forming a thin water film. This water film acts as a lubricant and prevents sticky pulp residue from adhering firmly to the roller surface, maintaining continuous cleanliness and working efficiency, and reducing the frequency of downtime for cleaning. Furthermore, the water penetrates and evaporates... The pulping process absorbs a large amount of heat, effectively controlling the temperature of the pulp after pulping. This prevents the pulp residue from spoiling or fermenting due to frictional heat, ensuring product flavor and hygiene. Simultaneously, low-pressure airflow nozzles blow the peeled pulp fragments from the roller surface towards the scraper. The ultrasonic vibrating scraper 34, through high-frequency micro-vibration, thoroughly removes any stubborn residue and guides it to the bottom of the separation chamber 31. A vibrating screen at the bottom rapidly shakes the mixture scraped down by the scraper, performing preliminary solid-liquid separation and screening to ensure that only pure pulp enters the pulp collection box 35. The pulp collection box 35 is equipped with a liquid level sensor and is detachable. Once the pulp level rises to the sensor's position, the worker disassembles the entire pulp collection box 35 to pour the pulp into the sterilizer. In addition, when production is finished or when regular cleaning is required, operators can thoroughly clean and disinfect the disassembled pulp collection box 35 from all angles, completely avoiding the cleaning blind spots and bacterial growth problems that may exist in fixed containers, and strictly complying with the hygiene standards for food processing.
