Description

Technical Field

[0001] This invention relates to the field of agricultural product deep processing and mechanical separation technology, and in particular to a flexible crushing and separation method and a continuous pulping system for extracting medicinal and edible homologous slurries. Background Technology

[0002] In the agricultural product processing industry, fresh goji berries are often processed into pulp to retain their internal components. Fresh goji berries consist of soft pulp and firm seeds, with pectin and polysaccharides distributed within the pulp. The physical processing steps for preparing goji berry pulp require crushing the fruit and separating the pulp from the seeds. When existing machinery applies external force to the material, the mechanical load often acts on the surface of the goji berry seeds. When the mechanical force exceeds the yield strength of the seed coat, it causes the seed coat to crack. After the shell cracks, the oils and secondary metabolites trapped inside the seed leak out and mix with the free pulp juice, altering the physicochemical composition of the resulting pulp.

[0003] Furthermore, the goji berry pulp obtained after crushing exhibits non-Newtonian fluid properties rheologically. During solid-liquid separation and pressing using a filter medium, the equipment applies pressure to the pulp. Water seepage leads to an increase in localized solids concentration, and colloidal and cell wall particles migrate towards the filter channels under the drive of fluid osmotic pressure, accumulating and agglomerating at the mesh openings. As the pressing process progresses, the accumulated pectin forms a water-blocking layer at the filter interface, increasing the resistance to liquid phase penetration through the filter channels. This physical blockage affects the fluid permeability of the system during continuous operation, typically requiring shutdown and backflushing to restore permeation flux, which increases the residence time during continuous production. Summary of the Invention

[0004] The purpose of this invention is to provide a flexible crushing and separation method and a continuous pulping system for extracting medicinal and edible pulps, in order to solve the problems mentioned in the background art, such as the crushing equipment easily causing damage and oil spillage of wolfberry seeds, and the high viscosity pectin easily causing filter mesh blockage during the pressing and separation process.

[0005] In a first aspect, the present invention provides a flexible crushing and separation method for extracting medicinal and edible homologous slurries, applicable to a continuous pulping system comprising crushing components, a porous inner cylinder, a non-porous outer cylinder, a flexible bag, and a drive shaft, the method comprising: The crushing component is controlled to compress fresh wolfberries to obtain a mixed pulp containing wolfberry flesh and wolfberry seeds; The mixed fruit pulp is introduced into the porous inner cylinder, and the porous inner cylinder is controlled to alternate between acceleration when powered on and sliding when powered off. Utilizing the speed reduction caused by the power-off gliding, the inertial difference between the goji berry seeds and the goji berry flesh causes the goji berry seeds and the goji berry flesh, which is slowed down by wind resistance, to slide relative to each other, separating the goji berry seeds and discharging the crude fruit pulp into the non-porous outer cylinder. The crude fruit pulp is guided into the flexible bag, and the drive shaft is controlled to rotate in the forward direction, forcing the non-porous outer cylinder to move downward and twist the flexible bag to extract the wolfberry pulp. During the pressing process before the downward displacement has ended, the forward rotation is periodically interrupted and a pulsed reverse extraction action is inserted; The pulse reverse action includes: controlling the drive shaft to reverse, forcing the non-porous outer cylinder to rise and untwist the flexible bag, using the internal negative pressure generated by the expansion of the flexible bag under the seal of pectin water to reversely remove the pectin embedded in the pores of the flexible bag, and then restoring the downward displacement after clearing the blockage.

[0006] Optionally, before the crushing component is used to crush the fresh goji berries, cold water is used to physically clean and pre-cool the fresh berries to be processed. Then, high-purity nitrogen is continuously injected into the crushing component to expel internal oxygen and create an anti-oxidation space.

[0007] Optionally, the crushing component is internally equipped with a variable pitch spiral propulsion roller and staggered obtuse-angle protrusions. By rotating the variable pitch spiral propulsion roller, a progressive thrust is applied to the fresh goji berries, and the obtuse-angle protrusions apply a blunt tearing force to avoid mechanical cutting that could damage the outer shell, thereby preventing the release of oil from the seeds.

[0008] Optionally, the drive shaft moves through the non-perforated outer cylinder and the bottom of the flexible bag, and the surface of the drive shaft is provided with external threads, and the bottom surface of the non-perforated outer cylinder is provided with internal thread holes that mesh with the external threads; During the pressing process before the downward displacement is completed, the threaded transmission effect forces the non-porous outer cylinder to move downward along the axial direction, while the drive shaft drives the chassis located at the bottom of the flexible bag to perform a torsional motion in the same direction.

[0009] Optionally, before starting the forward rotation of the drive shaft, a static filtration period is set, and the raw pulp is naturally filtered out through the pores of the flexible bag by the static pressure of the crude pulp itself. The drive shaft is then restarted to perform the forward rotation to extract the remaining juice.

[0010] Optionally, during the energization acceleration, working power is supplied to the motor that drives the porous inner cylinder to rotate, so that the porous inner cylinder is forcibly accelerated and drives the internal material to rotate at high speed in the same direction, closely adhering to the inner wall. When switching to the power-off coasting mode, the power supply to the motor is cut off, and the porous inner cylinder passively slows down only by relying on the system's frictional resistance.

[0011] Optionally, during the passive deceleration phase, the wolfberry seeds, which have a density greater than that of the pulp, maintain their original trajectory by accumulating kinetic energy, while the wolfberry pulp, which has a viscosity greater than that of the wolfberry seeds, decelerates due to air resistance and wall friction interference. The two phases slide relative to each other under conditions without rigid mechanical contact, physically severing the interconnected fiber bundles.

[0012] Optionally, when the pulse back-pull action is performed, the pectin seals the pores of the flexible capsule to form a dense, watertight isolation layer. The non-porous outer cylinder is lifted upward to relieve the external gravitational pressure and untwist, causing the internal three-dimensional space to rebound, resulting in a pressure drop in the sealed capsule cavity and generating the internal negative pressure.

[0013] Optionally, the pressing process, in which the downward displacement has not yet ended, is divided into multiple pressing stroke intervals. At the switching node of an adjacent pressing stroke interval, the pulse back-pulse action is inserted. The internal negative pressure is used to pull the flexible bag from the outside to the inside in the opposite direction, removing the gelatinous blockage embedded in the mesh channel and rolling it into the unfiltered pulp, thereby restoring the continuous pressing juice permeability.

[0014] In a second aspect, the present invention provides a continuous pulping system, including a frame, an actuator assembled inside the frame, and a control center; the actuator includes at least a crushing component, a porous inner cylinder, a non-porous outer cylinder, a flexible bag disposed inside the non-porous outer cylinder, and a drive shaft that moves through it; the actuator is controlled by the control center and is used to perform specific processing steps of the flexible crushing and separation method for extracting medicinal and edible homologous pulp as described in any of the first aspects.

[0015] The present invention has achieved the following beneficial effects: This invention applies a progressive thrust and non-sharp tearing force to fresh goji berries by configuring a variable-pitch spiral propulsion roller and an obtuse-angle protrusion structure. This causes the peel to tear along the surface texture, avoiding concentrated cutting force that could damage the goji berry seed shell and release the oil components inside the seed. Through the alternating operation of the porous inner cylinder and the power-off sliding control, the difference in apparent density and moment of inertia between the phase substances causes relative sliding between the goji berry seeds and the goji berry pulp, cutting off the interconnected fiber bundles and completing the physical separation of the solid and liquid phases. In the compression process of the flexible bag, the drive shaft is reversed by a pulse back-pull action, which drives the non-porous outer cylinder to rise and the bag to untwist. The physical rebound of the sealed bag volume generates internal negative pressure. The reverse hydrodynamic traction generated by this internal negative pressure removes the gelatinous blockages embedded in the mesh channels, clears the microscopic permeation channels of the filtration interface, reduces the probability of pectin solidifying and hardening at the micropores, and maintains the fluid permeability and extraction stability of the system under continuous pressing conditions.

Detailed Implementation

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] This application discloses a flexible crushing and separation method for extracting medicinal and edible homologous slurries, which is applied to a continuous pulping system including crushing components, a porous inner cylinder, a non-porous outer cylinder, a flexible bag, and a drive shaft. Figure 1 As shown, the continuous pulping system serves as the physical hardware carrier for executing the method, including a frame, execution hardware assembled inside the frame, and a control center. The execution hardware is controlled by the control center and is used to execute specific processing steps of the flexible crushing and separation method for extracting medicinal and edible homologous pulp.

[0021] Specifically, the frame serves as the three-dimensional physical support foundation for the continuous pulping system. The execution hardware is arranged sequentially along the material flow path, including electromechanical components such as crushers responsible for phase transformation, a porous inner cylinder for centrifugal decoupling, a non-porous outer cylinder, and flexible bags for volumetric pressing. The control center is equipped with an industrial-grade programmable logic unit (PLU), an analog-to-digital converter (ADC), and a communication interface. It establishes a bidirectional data link with servo drives, frequency converters, regulating valves, and physical quantity sensors distributed across the execution hardware via an industrial fieldbus. Based on a built-in closed-loop control algorithm, it controls the displacement coordinates, angular velocity phase, electromagnetic torque, and fluid system pressure distribution of the execution hardware. Before receiving and processing materials, the control center reads the absolute position encoder parameters, drives each mechanical execution component to reset to the reference origin, and performs pipeline tightness pressure holding tests and stores the motor no-load reference current parameters, which serve as a differential reference for subsequent identification of load torque changes.

[0022] The method flow provided by this invention is as follows: Figure 2 As shown, it includes: Step S10: Control the crusher to squeeze the fresh goji berries to obtain a mixed fruit pulp containing goji berry flesh and goji berry seeds.

[0023] It is understandable that before the crushing component is used to crush the fresh goji berries, cold water is used to physically clean and pre-cool the fresh berries to be processed. Then, high-purity nitrogen is continuously injected into the crushing component to expel internal oxygen and create an anti-oxidation space.

[0024] Specifically, after the fresh goji berries to be processed are quantitatively fed into the pretreatment station, the control center adjusts the output parameters of the cooling medium water. The cooling medium water is transformed into a cold water jet through pipe nozzles to continuously wash the surface of the fresh berries, removing attached impurities. At the same time, the cold water acts as a heat exchange carrier to perform targeted cooling of the fresh berries to be processed. The control system performs thermodynamic closed-loop regulation based on the proportional valve of the circulating cooling medium flow rate, setting the lower limit of the target low temperature range of this precooling operation to a safe offset of 1.0℃~1.5℃ higher than the initial crystallization freezing point of the free liquid phase in the cells of the same batch of fresh berries. This fundamentally blocks the path of volume expansion caused by the freezing of the free water phase, which would then pierce the outer shell of the goji berry seeds from the inside out. Simultaneously, the upper limit of its thermodynamics is controlled below the critical inflection point temperature at which the high molecular weight pectin in the pulp undergoes a rheological phase transition from a Newtonian fluid to a pseudoplastic state, and the kinematic viscosity exhibits a step-like increase. In practical engineering settings, the critical inflection point temperature is based on pre-shipment sampling calibration: Juice samples from the same batch of fresh fruit are extracted and continuously measured using a rotational viscometer at a cooling rate of 1℃ / min. When the relative viscosity increase within a single 1℃ temperature drop range first exceeds 20%, the system statically calibrates the corresponding temperature value as the critical inflection point temperature. For conventional Ningxia wolfberries, this empirical temperature threshold is typically fixed in the range of 4.0℃ to 8.0℃, directly eliminating the high computational load on the underlying layers. Pre-cooling within this controlled metastable temperature range not only limits the catalytic activity of enzymes within the pulp; the peel tissue undergoes a shrinkage effect, increasing its tensile elastic modulus and decreasing its elongation at break; but also increases the kinematic viscosity of polysaccharides and pectin substances within the pulp due to cooling.

[0025] After washing and pre-cooling, the fresh fruit is introduced into the sealed internal cavity of the crushing component via a rotary airlock valve. A high-purity nitrogen source is activated at the control center, and the nitrogen is injected through a microporous gas distribution plate at the bottom of the crushing component cavity. Based on density differences, a laminar gas displacement field is constructed from bottom to top, discharging the original oxygen-containing air in the cavity through a one-way pressure relief exhaust valve at the top. The stabilization of the anti-oxidation space abandons open-loop constant flow compensation, instead relying on a cascade control loop combining an oxygen concentration probe and an absolute pressure transmitter. During the initial pre-charging stage, a large-flow displacement is performed based on the oxygen concentration feedback from the exhaust channel. When the residual oxygen volume concentration drops below 0.5%, it automatically switches to a low-pressure stabilization mode. The control center dynamically biases the target static pressure reference to 1.5 to 3.0 kPa higher than the current ambient atmospheric pressure and substitutes the high-frequency collected pressure residual into the proportional-integral control equation to continuously modulate the throttling area of ​​the proportional solenoid valve core. This mechanism forces the transient mass flow rate of dynamically injected nitrogen to achieve a physical equation conservation with the microscopic escape rate at the mechanical dynamic seal of the main shaft, thereby offsetting the dynamic leakage of the system and stably constructing and maintaining the anti-oxidation space with a constant positive pressure gradient inside the broken parts, effectively blocking the oxidative reverse penetration and degradation path of the pulp components.

[0026] Combination Figure 3The internal structure shown includes a variable pitch spiral propulsion roller and staggered obtuse-angle protrusions coaxially mounted inside the anti-oxidation space. By rotating the variable pitch spiral propulsion roller, a progressive thrust is applied to the fresh goji berries, and the obtuse-angle protrusions apply a blunt tearing force to avoid mechanical cutting that could damage the outer shell, thereby preventing the release of oil from the seeds.

[0027] Specifically, the variable-pitch spiral propulsion roller has spiral blades fixedly connected to its surface, and the axial lead spacing between adjacent spiral blades decreases along the material propulsion direction. Driven by a servo motor, the propulsion roller rotates at a constant speed in the forward direction within the stator cavity. Fresh goji berries falling into the spiral groove are translated axially by the normal thrust of the spiral blades. Constrained by the reduced lead, the volume enveloped by adjacent blades and the inner wall of the stator is continuously compressed, applying the progressive thrust to the group of fresh berries entering this area. The hydrostatic pressure inside the fresh berries increases gradually with displacement, forcing the berries to be under tension.

[0028] Furthermore, the obtuse-angle protrusions are arrayed on both the outer surface of the variable-pitch helical propulsion roller and the inner wall of the stator cavity. This structure has a smooth surface without cutting edges, and its end radius of curvature is configured to be greater than the critical curvature parameter for compressive yield of fresh goji berry peel, and also greater than the average outer radius of a single goji berry seed. Samples of pre-cooled goji berries from the same batch were extracted, and normal compression puncture tests were performed using multiple sets of rigid spherical probes with different radii of curvature on a texture analyzer. The minimum probe radius of curvature at the moment irreversible fiber breakage of the peel was recorded and physically calibrated as the critical curvature parameter for compressive yield. Simultaneously, the three-dimensional outline of the sampled goji berry seeds was scanned using a coordinate measuring machine, and the radius of the inscribed circle of the largest cross-section was taken as the average outer radius of a single goji berry seed. When manufacturing the variable-pitch helical propulsion roller, the larger of the two measured parameters was taken and directly multiplied by a physical safety tolerance coefficient of 1.15 to 1.25. This product result was used to determine the physical machining dimension of the end radius of curvature of the obtuse-angle protrusions. This micromechanical constraint ensures that the normal compressive load generates stress dispersion at the contact interface, forcibly suppressing the local compressive stress peak within the plastic elongation boundary of the peel, thus blocking the path of stress concentration leading to sharp-angle puncture and shearing of the seed shell from the physical source of force. When the compressed and taut fresh fruit is pushed through the gap of the obtuse-angled protrusion structure, the protrusion surface is pressed into the peel deformation zone. The static friction between the fresh fruit and the contact surface of the obtuse-angled protrusion structure, caused by the linear velocity of the fresh fruit moving with the spiral blades, generates shear stress in a local area of ​​the peel. This shear stress and the normal forced deformation force are vector-superimposed to form the non-sharp tearing force. Due to the decrease in peel elongation at break caused by pre-cooling, the tensile strain generated by the non-sharp tearing force exceeds the fracture limit of the peel under this thermodynamic state, and the peel undergoes extensible tearing along the fiber texture, with the viscous pulp and juice overflowing from the tear.

[0029] Simultaneously, when the hard-shelled goji berry seeds come into contact with the smooth, obtuse-angled protrusions, they cannot generate cutting stress that penetrates the shell. The overflowing, highly viscous pulp juice acts as a fluid lubricant at the solid-liquid interface, guiding the goji berry seeds to undergo compliant rolling and lateral sliding displacement at the pressure interface, converting the normal pressure into work done against friction. This kinematic transformation mechanism prevents mechanical cutting actions from damaging the goji berry seed shell. After this process, the input material phase is transformed into a mixed pulp containing disintegrated peel, free pulp juice, and intact goji berry seeds, and is discharged from the discharge port.

[0030] Step S20: The mixed fruit pulp is introduced into the porous inner cylinder, and the porous inner cylinder is controlled to alternate between power-on acceleration and power-off sliding.

[0031] The mixed fruit pulp, possessing non-Newtonian fluid properties, is metered into the bottom physical chamber of a porous inner cylinder via a delivery pump. The porous inner cylinder is a hollow cylindrical component with rotational balance precision, and its circumferential walls are perforated. The perforation diameter threshold is set to be greater than the equivalent outer diameter of the fruit pulp fiber fragments but less than the minimum cross-sectional size of the goji berry seeds. The control center sends control pulses to the asynchronous motor connected to the main shaft via a frequency converter drive module, executing an alternating operation program.

[0032] During the acceleration process, working electrical energy is supplied to the motor driving the porous inner cylinder, causing the porous inner cylinder to accelerate and drive the internal material to rotate at high speed in the same direction, adhering tightly to the inner wall. The frequency and voltage amplitude of the electrical energy output to the stator winding of the main shaft motor are not constant presets, but are controlled by the rheological control boundaries to avoid micro-emulsification of the pulp and pectin chain breakage.

[0033] The control center has a pre-stored temperature-viscosity reference database, which is constructed based on rotational viscometer measurements of goji berry samples with different sugar contents at various temperature gradients. The control center obtains the real-time apparent viscosity of the material by using a lookup table and linear interpolation based on real-time pre-cooling temperature sensor readings. After the processing unit extracts the apparent viscosity of the mixed fruit pulp, the system directly calls the internally stored viscosity-limiting angular acceleration two-dimensional mapping matrix. This matrix was determined and input into the system through offline microscopic bench pulping experiments during the early stages of development. The control center can directly retrieve the maximum allowable shear rate of the main shaft to ensure the pectin chain does not break by lookup table interpolation. The underlying frequency conversion drive module equivalently maps this hydrodynamic extreme value to the limiting angular acceleration parameter of the porous inner cylinder during the initial stage, and generates a restricted voltage-frequency (V / f) ramp slope command based on this physical upper limit. It outputs a flexible electromagnetic torque to overcome the system's static friction and rotational inertia, driving the porous inner cylinder to accelerate positively along this safe mechanical boundary. In practical engineering applications, the extreme value mapping is based on an empirical data table obtained from factory calibration tests. Specifically, the control center pre-stores an acceleration-V / f slope mapping table for different goji berry varieties and pre-cooling temperatures. After reading the current temperature sensor data, the computing unit directly calls the corresponding empirical value of the limiting angular acceleration in the mapping table (usually calibrated to 2.5~4.0 rad / s²), which serves as the safety control boundary for the frequency converter. This mapping table is established through prototype calibration tests before leaving the factory: for different goji berry varieties, at different pre-cooling temperatures, pulping tests are conducted with angular acceleration increments of 0.5 rad / s². Microscopic observation equipment is used to monitor whether there is pectin chain breakage or unexpected emulsification in the pulp, and the critical angular acceleration without physical damage is recorded as the mapping value under that operating condition.

[0034] To facilitate direct table lookup in the PLC control center, a set of offline empirical mapping benchmark data tables is provided here for conventional Ningxia fresh goji berries (sugar content 12% to 15%) within the core pre-cooling temperature zone: when the real-time pre-cooling temperature is 4.0℃, the corresponding limiting angular acceleration safety boundary is calibrated to 2.5 rad / s²; when the pre-cooling temperature is 6.0℃, the limiting angular acceleration is calibrated to 3.2 rad / s²; and when the pre-cooling temperature is 8.0℃, the limiting angular acceleration is calibrated to 4.0 rad / s². In actual pressing control, the system only needs to perform basic linear interpolation calculations between the above discrete empirical data points based on the temperature values ​​measured by the sensors to generate a continuous safety control curve.

[0035] This mechanism forces the mixed fruit pulp to maintain a stable laminar spread in a gently rising centrifugal radial field, avoiding unintended emulsification of the solid and liquid phases caused by the abrupt activation of high-energy turbulent vortices due to sudden changes in driving torque. The introduced mixed fruit pulp, subjected to centrifugal force that increases with rotational speed, overcomes gravity and spreads upwards along the inner wall. Under the combined constraints of internal viscous shear stress and static friction on the wall, the mixed fruit pulp spreads into a uniformly thick annular fluid material layer on the inner wall. Interlayer friction drags the tangential linear velocity of each component, gradually increasing until it matches the linear velocity of the inner wall. The two phases enter a relatively static co-rotational state in the radial section, accumulating rotational kinetic energy within the system.

[0036] When switching to the power-off coasting mode, the motor power is cut off, and the porous inner cylinder passively slows down only due to system frictional resistance. The control center issues a disconnect contactor command constrained by dual dynamic parameters: the centrifugal separation threshold and the residence time setting. The extraction of the centrifugal separation threshold is based on the transient momentum decoupling force balance equation at the solid-liquid interface. The computing unit retrieves the ultimate tensile strength of the fiber bundle connecting the wolfberry seed and the pulp, as well as the equivalent mass of a single wolfberry seed. The ultimate tensile strength is measured using the tensile mode of a texture analyzer, with a typical range of 0.5N~1.2N; the equivalent mass of a single wolfberry seed is obtained by random sampling and weighing using a 0.015g~0.035g balance. These parameters are preset as static constants in the control center for threshold determination of the underlying momentum decoupling equation.

[0037] Based on the rotation radius of the porous inner cylinder, the tangential inertial centrifugal force accumulated by a large mass of goji berry seeds at the instant of power failure was calculated in reverse. This force exceeded the lower limit of the critical angular velocity for the sum of the viscosity damping of the fruit pulp and the tensile force vector of the fiber bundle. After adding a 15% kinetic energy dissipation compensation margin to this lower limit of angular velocity, it was assigned as the centrifugal separation threshold of the system. The extraction of this centrifugal separation threshold follows the critical kinetic inequality: in The equivalent weight of a single goji berry seed. The radius of rotation of the porous inner cylinder is... This is the lower limit of the critical angular velocity. These are the measured tensile force and fluid resistance force, respectively. Considering the simplicity of on-site implementation, the fluid resistance force... The resistance was obtained using a simple offline empirical calibration method. The manufacturer measured the steady-state average resistance by uniformly dragging a standard wolfberry seed sample through a mixed fruit pulp sample at a standard operating temperature (4℃ to 8℃). This resistance was applied to standard Ningxia wolfberries. The empirical constant range is statically calibrated to be 0.2N to 0.6N, serving as the preset constant parameter for the computing unit. This centrifugal separation threshold is determined through centrifugal sampling observation during equipment commissioning. For typical fresh Ningxia wolfberries, this threshold is typically calibrated to 60%–75% of the rated rotational speed of the porous inner cylinder. The residence time constant corresponds to the momentum transfer lag period of a non-Newtonian fluid from the bottom to the periphery. It is set to ensure that the pulp adhering to the innermost ring of the porous inner cylinder wall fully absorbs kinetic energy and eliminates the relative slip velocity gradient of the overall cross-section, allowing for hydrodynamic relaxation. This residence time constant is controlled by the PLC's internal timer, and its empirical value range is set to 3.0 to 5.0 seconds based on the actual inner cylinder diameter.

[0038] After the main shaft accelerates to the centrifugal separation threshold, the internal clock is activated. Once the residence time constant is exhausted and the flow field linear velocities are confirmed to be synchronized, the control center immediately commands the contactor to disconnect, and the system enters a passive deceleration state. The porous inner cylinder, deprived of electromagnetic power, transforms into an inertial rotating decaying body. Under the combined dissipation of the rolling resistance of the main bearing, the air gap resistance, and the fluid shear air resistance on the outer surface of the porous inner cylinder, its rotational angular velocity curve exhibits a passive decay characteristic.

[0039] Step S30: Utilizing the speed reduction caused by the power-off gliding, the inertial difference between the goji berry seeds and the goji berry pulp causes the goji berry seeds and the goji berry pulp, which is slowed down by wind resistance, to slide relative to each other, thereby separating the goji berry seeds and discharging the crude fruit pulp into the non-porous outer cylinder.

[0040] like Figure 4 The separation mechanism shown is that, in the passive deceleration stage, the wolfberry seeds with a density greater than that of the pulp maintain their original trajectory by accumulating kinetic energy, while the wolfberry pulp with a viscosity greater than that of the wolfberry seeds decelerates due to air resistance and wall friction interference. The two phases slide relative to each other under conditions without rigid mechanical contact, physically severing the interconnected fiber bundles.

[0041] Based on the difference in apparent mass density, goji berry seeds acquire corresponding translational and rotational inertia during the acceleration phase under power. During deceleration after power failure, limited by the momentum transfer efficiency of the fluid boundary layer, the pulp fluid cannot provide tangential braking force for synchronous deceleration of the solid particles. Following the law of inertia, goji berry seeds with a density greater than that of the pulp tend to overcome fluid viscous resistance and maintain their original trajectory with a tangential linear velocity close to that at the instant of power failure. In contrast, the highly viscous goji berry pulp, containing high-molecular-weight pectin and reticular fibers, is constrained by the rigid boundary of the porous inner cylinder wall due to deceleration friction at its bottom layer. The inner free fluid surface and the central relatively stationary air column undergo shearing, generating a stagnant vortex. Under the dual dissipation disturbance, the kinetic energy of the low-density goji berry pulp drops, and its tangential linear velocity is rapidly lost as the inner cylinder rotation speed decreases.

[0042] The asynchronous movement of goji berry seeds at high speed and the deceleration of goji berry pulp due to frictional damping creates a steep velocity gradient difference. This vector difference forces the two phases to displace and migrate without external rigid intervention. The relative slip action at the fluid interface between the goji berry seed shell and the attached pulp is converted into hydrodynamic parallel shear stress. When the shear stress exceeds the tensile yield limit of the natural pectin fiber bundles connecting the goji berry seeds and pulp, the fiber bundles are physically severed.

[0043] Once freed from the colloidal network, the goji berry seeds are separated into discrete particles and slide down the cylinder wall to the dedicated slag discharge channel at the bottom as the rotational speed of the porous inner cylinder decreases and the centrifugal force diminishes. Fruit pulp fragments and free liquid juice, whose structure has been sheared and whose rheological viscosity has decreased, are driven by the residual centrifugal dynamic pressure to penetrate the array of perforations in the porous inner cylinder and ejected. The ejected material impacts the inner wall of the non-porous outer cylinder, which is coaxially wrapped around it, and converges into a liquid fluid film. Following the direction of gravity, the separated, seed-removed coarse pulp is discharged into the collection tank at the bottom of the non-porous outer cylinder.

[0044] Step S40: Guide the crude fruit pulp into the flexible bag and set the settling and filtration period.

[0045] The collecting groove at the bottom of the non-porous outer cylinder connects to the guiding channel. The control center opens the pneumatic valve in the pipeline, guiding the crude fruit pulp into the internal cavity of the flexible bag. The flexible bag is woven from a high-polymer polymer filament material that meets contact standards, with micron-level permeation pores on its sidewalls. These pores allow monosaccharides and low-kinematic-viscosity liquid molecules to penetrate, while physically intercepting fruit pulp cell wall debris and coarse plant fibers. The upper opening of the flexible bag forms a sealed rigid connection with the non-porous outer cylinder support ring, and the bottom end is fixedly connected to the chassis component at the bottom of the drive shaft to prevent rotation, constructing a variable-volume closed chamber with constrained upper and lower boundaries.

[0046] Before initiating the forward rotation of the drive shaft, a static filtration period is set, during which the crude fruit pulp naturally filters out through the pores of the flexible bag using its own static pressure. During the static filtration period, the control center maintains the main mechanical transmission link in a zero-speed locked state. The crude fruit pulp filled inside the bag forms a fluid column under the influence of gravity, generating a linearly distributed hydrostatic pressure across its depth section, creating a unidirectional transmembrane pressure gradient between the inner and outer walls of the bag. The free-floating aqueous phase and dissolved solids, with low viscosity, overcome the capillary damping of the pore channels and filter out naturally according to kinetic laws to form the original pulp. During this stage, there is no mechanical shearing force, and the suspended high-viscosity pectin is not forced into the micron-sized pores, thus maintaining the unobstructed filtration cross-section. Static dehydration increases the solid mass fraction of the residual material, and the plant fiber network overlaps to form a rigid semi-solid skeleton structure, setting uniform force transmission boundary conditions for subsequent mechanical compression.

[0047] Step S50: Control the drive shaft to rotate in the forward direction to force the non-porous outer cylinder to move downward and twist the flexible bag to extract the wolfberry juice.

[0048] The drive shaft moves through the non-perforated outer cylinder and the bottom of the flexible pouch, and the surface of the drive shaft is provided with external threads, while the bottom surface of the non-perforated outer cylinder is provided with internal threaded holes that engage with the external threads; for example Figure 5 As shown in the pressing operation state, during the pressing process before the downward displacement is completed, the non-porous outer cylinder is forced to move downward along the axial direction by utilizing the thread transmission effect, while the drive shaft drives the chassis located at the bottom of the flexible bag to perform a torsional action in the same direction.

[0049] The control center sends angular velocity commands to the motor to drive the drive shaft to rotate in the forward direction, which are constrained by the physical limits of fluid permeation through the microporous medium. If the absolute shrinkage rate of the mechanical geometric volume exceeds the actual physical escape rate of the fluid through the micron-sized pores, the incompressible liquid phase accumulated in the sealed cavity will trigger a transient water hammer pressure surge, which will then lead to the rupture of the flexible fabric bladder.

[0050] Based on this transmission constraint, the computing unit invokes Darcy's Law in porous media fluid dynamics. Combining the current effective total filtration area of ​​the bag with the dynamic permeability damping coefficient of the pulp, this system simplifies the pressure control condition that ensures the ultimate tensile yield strength of the bag matrix is ​​not exceeded into a constant safe internal pressure physical upper limit (0.3MPa~0.4MPa in this embodiment). This safe internal pressure upper limit is obtained by the manufacturer through destructive testing of the bag using a hydrostatic burst test bench and is written into the control center as a static constant.

[0051] The control center substitutes this safe internal pressure upper limit into Darcy's law, and, combined with the current effective filtration area of ​​the bladder, calculates the maximum allowable fluid permeation volume rate. Specifically, the system simplifies Darcy's law in engineering terms into a linear algebraic equation: in, For the maximum fluid permeation volume rate, The aforementioned upper limit for safe internal pressure, This represents the current effective filtration area; while The overall permeability damping constant is obtained by the manufacturer through offline pressing tests and written into the control center as a static constant.

[0052] The offline pressing test uses a conventional constant-pressure filter cup for physical equivalence measurement. Specifically, a microporous flexible filter screen of the same material is laid at the bottom of the filter cup, and an equal volume of pre-cooled fruit pulp is added. A constant test pressure of 0.3 MPa is applied using an air source, and the volume of liquid filtered per unit area per unit time is recorded using a graduated cylinder. This macroscopic performance is then used to inversely extrapolate the results. Value. Its dimensional engineering simplifies to the ratio of flow velocity to pressure. For the polymer bag material and non-Newtonian fluid fruit pulp used in this embodiment, this... The effective empirical range of values ​​for the constant is defined as 1.2 × 10⁻ 4 Up to 2.5×10⁻ 4 m / (s•MPa).

[0053] Total effective permeation area of ​​the current capsule during the pressing process The calculation is performed using an equivalent attenuation model based on axial displacement: in The initial unfolded area of ​​the capsule. For the current displacement, This represents the initial effective axial height of the capsule. To account for the area reduction factor caused by torsional wrinkling, it was back-calibrated using the permeability of different strokes measured under hydrostatic testing on the prototype, with a value ranging from 0.85 to 0.95. The system then uses this volumetric velocity to calculate the maximum allowable axial translational linear velocity of the non-perforated outer cylinder, and then, using the helix angle parameter of the drive shaft's external thread, converts it into the upper limit of the absolute rotational speed for the drive spindle in the forward direction. This conversion process uses the basic mechanical transmission formula: the maximum allowable fluid permeation volumetric velocity divided by the inner cross-sectional area of ​​the non-perforated outer cylinder yields the maximum allowable axial translational linear velocity. Then, according to the formula To obtain the absolute speed safety limit, where The known lead parameters are for the external thread of the drive shaft. The underlying data for the aforementioned physical limits (such as the water-permeable damping coefficient) were all measured in a single test using a prototype extrusion experiment with conventional solid-liquid separation testing equipment and then solidified within the control center. The control system consistently distributes motor operation commands within these dynamically calculated physical threshold boundaries.

[0054] Under controlled rotation, the high-rigidity linear guide assemblies arranged around the periphery of the non-perforated outer cylinder are connected to the frame, physically constraining and limiting the circumferential rotational freedom. The rotational torque input by the drive shaft undergoes kinematic vector transformation at the contact surface of the threaded pair, decomposing into a linear translational thrust along the central axis. This thrust overcomes the self-weight of the moving components and the elastic reaction force of the fluid in the bladder, using the threaded transmission effect to force the non-perforated outer cylinder to perform a smooth downward displacement. As the non-perforated outer cylinder is pressed down, the flexible bladder enveloping it is subjected to axial absolute geometric compression. Simultaneously, the bottom end of the drive shaft drives the supporting chassis to rotate in the same phase via an anti-rotation spline. The chassis drives the bottom end of the flexible bladder to perform a torsional motion in the same direction.

[0055] Under the dual mechanical constraints of axial translation and chassis rotation, the flexible capsule matrix simultaneously endures axial linear compressive strain and circumferential helical torsional shear strain, causing the capsule to wrinkle and deform, and its three-dimensional volume to shrink rapidly. The isotropic static pressure of the fluid inside the capsule increases with the reduction in volume. This high pressure gradient overcomes the capillary binding of plant tissue and the friction resistance of the filter cake layer, forcing the bound juice in the concentrated network skeleton to permeate through the micropores of the capsule wall and complete the mechanical pressing extraction.

[0056] Step S60: During the pressing process before the downward displacement has ended, the forward rotation is periodically interrupted and a pulsed reverse extraction action is inserted.

[0057] As the liquid phase components are removed, the concentration of high molecular weight substances within the material increases. Under forced dehydration and fluid shearing, the endogenous pectin-like substances undergo conformational rearrangement, exhibiting gelation and shear thickening characteristics. Under the drag of unidirectional fluid osmotic pressure, highly viscous pectin and cell wall remnants are pressed to the inner surface of the flexible capsule and forcibly injected into the physical channels of the permeation mesh. Colloidal particles agglomerate at the cross-section of the channels, and pectin seals the pores of the flexible capsule, forming a continuous watertight isolation layer. This effect cuts off the permeation pathway of the juice, leading to a decrease in overall permeability. The incompressible medium causes the mechanical work of the non-porous outer cylinder to be converted into internal stress within the system, resulting in an abnormal increase in the motor load current.

[0058] To proactively intercept permeability decay caused by porosity blinding, the control center abandons the mechanical logic of statically dividing the downward stroke into equal intervals. Instead, it employs a dynamic node capture mechanism based on the physical impedance feedback of the drive motor's electromagnetic torque to define the downward stroke range. As the polymer pectin migrates into the mesh channels and forms a watertight isolation layer, the incompressible medium within the sealed chamber forces the downward mechanical energy to be rapidly converted into rigid resistance work by the motor rotor. The servo layer acquires the stator-side active current torque component in real time with a microsecond-level sampling period. The computational logic calculates the first derivative of the current sequence over time. Once the real-time differential derivative is detected to exceed the calibration threshold of the no-load reference current drift rate within five consecutive sampling clocks, and the absolute amplitude reaches the fixed percentage extreme value of the full-load rated current, it can be confirmed that the mesh has entered deep physical consolidation. The calibration threshold for the no-load reference current drift rate is set to 0.15A~0.25A / clock cycle (clock cycle is usually 100ms), and the fixed percentage extreme value of the full-load rated current is set to 80%~85% of the motor's rated full-load current. At the instant the judgment condition is met, the control loop acquires the current mechanical spatial absolute displacement coordinates fed back by the position encoder in real time and anchors them locally as the dynamic switching node of the pressing stroke range. After confirming this switching node, the control center forcibly cuts off the positive electromagnetic torque command, driving the spindle's positive angular velocity to decay to zero within the clock cycle, thus interrupting continuous pressing.

[0059] Subsequently, the pulse counter-pulsation action is inserted at the switching node of the adjacent downward stroke interval. For example... Figure 6 As shown in the unblocking state, the pulse reverse action includes: controlling the drive shaft to reverse, forcing the non-porous outer cylinder to rise and untwist the flexible bag, using the internal negative pressure generated by the volume expansion of the flexible bag under the pectin water seal to reversely remove the pectin embedded in the pores of the flexible bag, and restoring the downward displacement after unblocking.

[0060] The control center sends a reverse control pulse to the actuator, controlling the drive shaft to perform a reverse motion. Based on the kinematic relationship of the helical transmission, the reverse rotation of the drive shaft applies an upward axial thrust through the threaded contact surface, forcing the non-perforated outer cylinder to rise linearly along the vertical axis, releasing the axial forced compression on the upper part of the flexible bag. Simultaneously, the reverse rotation of the drive shaft drives the chassis to perform a reverse rotation, forcibly untwisting the flexible bag and releasing the elastic strain energy stored in the bag's woven substrate.

[0061] During the pulsed back-pull action, the pectin seals the pores of the flexible capsule, forming a dense, watertight isolation layer. The non-porous outer cylinder rises, relieving external gravitational pressure and causing the internal three-dimensional space to rebound, resulting in a pressure drop within the sealed capsule and generating the internal negative pressure. After the combined constraints of mechanical disengagement and torsion are released, the flexible capsule expands in volume. Since all the permeation mesh pores are tightly sealed by the watertight isolation layer, the internal cavity transforms into a closed system with constant gaseous and solid-liquid mass. According to Boyle's law under isothermal boundary conditions, the forced step increase in the internal volume of the closed system leads to a sharp, inversely proportional drop in the absolute static pressure. This pressure drop causes the static pressure inside the capsule to fall below the external standard atmospheric pressure, thereby generating the internal negative pressure.

[0062] The internal negative pressure creates a reverse pressure gradient at the geometric boundaries of the inner and outer sides of the permeation mesh, pointing from the external environment towards the central axis of the bladder cavity. Driven by this gradient, the external atmospheric pressure and the residual liquid fluid on the outside of the bladder are transformed into an inward hydrodynamic reverse traction vector. This internal negative pressure generates reverse pulling work from the outside to the inside of the flexible bladder, applying a reverse drag force to the embedded gelatinous blockage. When the local shear stress generated at the pectin contact interface by the reverse traction force exceeds the physical adhesion between the pectin and the inner wall of the mesh, as well as the fluid friction resistance, the gelatinous blockage embedded in the mesh channel is removed.

[0063] The pectin structure, freed from boundary constraints, is drawn back into the unfiltered pulp by the reverse fluid. The accompanying torsional motion generates localized fluid eddies, which disperse and decouple the enriched pectin clusters within the main fluid phase. The extreme displacement of the non-porous outer cylinder during the pulsed reverse suction is controlled by the volumetric mapping calculation of the isothermal expansion process in the sealed chamber. The control system locks the absolute geometric volume of the cavity, which is blocked by the pectin water seal during the transient state triggered by the cutoff command, as the equivalent initial gaseous volume, and sets the initial internal pressure to standard atmospheric pressure. The pressure drop boundary value is actually obtained by the PLC control unit calling a set of offline vacuum calibration data tables. Before shipment, the manufacturer manually squeezes pectin into the same material mesh using a vacuum simulation test bench and records the minimum critical vacuum level when the blockage is successfully removed. The control center directly reads the empirical test value of the critical vacuum degree (usually -15kPa to -25kPa) as the boundary value of the reverse suction pressure drop, and then substitutes it into Boyle's law isothermal equation of state to perform conventional volume deduction.

[0064] The limiting shear adhesion friction coefficient between pectin and the inner wall of the mesh is an empirical engineering constant, determined offline by measuring the initial osmotic pressure difference and flow rate change curves of the pectin concentrate on a filter cloth with a specific porosity, combined with a fluid shear model. For the flexible bag material selected in this embodiment, this coefficient is set in the range of 0.12 to 0.18. Before leaving the factory, using this friction coefficient as the resistance boundary condition, the theoretical lower limit of the pressure drop required to remove pectin is calculated offline using the static mechanical equilibrium equation. This theoretical lower limit guides the calibration of the aforementioned vacuum simulation test bench, thereby establishing the empirical test value of the critical vacuum degree that can be directly called by the control center. Therefore, the control center only performs gaseous isothermal simulations during the actual pressing process and does not involve the online coupling of this friction coefficient.

[0065] Substituting the initial volume, atmospheric pressure, and pressure drop boundary values ​​into Boyle's law isothermal equation of state, the necessary forced expansion volume increment of the bladder to generate the negative pressure is calculated. Based on the cascaded mathematical relationship between this volume increment, the equivalent cross-sectional area of ​​the flexible bladder, and the lead parameters of the drive shaft's external thread, the servo control logic accurately converts and maps this volume increment into the upward vertical reverse translational target displacement that the drive spindle needs to perform. Considering the simplicity of engineering control, the forced expansion volume increment of the bladder... The volume is set to 5%~8% of the equivalent initial volume inside the cyst cavity at the moment of triggering. The servo control logic uses direct geometry mapping to increment this volume. Divide by the effective cross-sectional area of ​​the flexible bag The required vertical reverse translation target displacement can then be obtained. Then, based on the aforementioned thread lead parameters, This is converted into the number of reverse pulses of the motor. When the absolute encoder detects that the mechanical lifting stroke has strictly reached the extreme point of the calculated displacement, the reverse suction work at the fluid physics level has met the standard, confirming that the pores are cleared. The system then blocks the reverse drive command, reverses the stator current phase sequence, and re-controls the main shaft to resume forward operation. After the poreless outer cylinder is cleared, the downward displacement resumes, and the system enters the next set downward stroke range to continue mechanical extrusion, ensuring continuous pressing and juice extraction throughout the entire cycle.
