Fruit juice – whether apple, orange, grape or mango – contains a large amount of solid impurities after pressing or pulping: pulp fibres, peel fragments, seed pieces, coarse fibre, and trace foreign matter that may be introduced during processing. If these impurities are not effectively removed, they will directly affect the clarity of the juice, taste stability, and the smooth operation of subsequent filling and sterilisation processes.
In actual production, juice filtration is typically divided into two stages: coarse filtration and fine filtration. Coarse filtration uses a relatively coarse screen (e.g., 20 mesh) to remove large particles such as peel fragments, membrane, coarse pulp and seeds. Fine filtration uses finer screens (e.g., 80 mesh, 120 mesh or even 200 mesh) to further remove fine suspended solids and fibre residues. Traditional filtration methods often require multiple equipment units to complete the process – dispersed steps, low efficiency, and multiple material transfer points.
Is there a piece of equipment that can complete the stepwise separation from coarse filtration to fine filtration in a single machine?
The Gaofu S49 series fruit juice rotary vibrating sieve is a professional machine designed specifically for this need. With a multi‑deck screen structure for stepwise filtration, three‑dimensional gyratory motion for efficient solid‑liquid separation, and food‑grade stainless steel for hygiene safety, it efficiently transforms fruit juice from "cloudy raw juice" to "clear fruit juice" in a single machine.
The Gaofu S49 series fruit juice rotary vibrating sieve operates on the three‑dimensional gyratory motion principle. The equipment uses a vertical vibration motor as the excitation source, with eccentric weights installed at the upper and lower ends of the motor shaft converting the rotational motion into compound motion in horizontal, vertical and tilting directions, which is then transmitted to the screen deck. By adjusting the phase angle of the upper and lower weights, the motion trajectory of the material on the screen surface can be changed to suit the filtration requirements of different fruit juices.
The value of this three‑dimensional motion for juice filtration lies in three aspects:
First, rapid spreading of the liquid for efficient passage through the screen. The high‑frequency, low‑amplitude excitation force causes the juice to spread quickly into a thin layer on the screen surface, reducing flow resistance and allowing the liquid to pass through the screen rapidly. The S49 series rotary vibrating sieve can achieve screening fineness up to 600 mesh (0.02 mm) and filtration precision down to 5 microns. From 20‑mesh coarse filtration to fine filtration above 200 mesh, a single machine with multiple screens covers the full range of requirements.
Second, automatic discharge of impurities for continuous operation. Solid impurities retained on the screen surface – such as pulp fibres and peel fragments – move along the screen under vibration and are automatically discharged from the reject port. The equipment can run 24 hours continuously without frequent stoppages for cleaning, effectively supporting large‑scale continuous juice production.
Third, multi‑deck classification – one machine, multiple uses. The equipment supports 1 to 5 screen decks , enabling simultaneous separation into 2 to 6 grades. From coarse filtration to remove large peel and seed particles, to fine filtration for clear, bright juice, a single machine completes multiple filtration steps.
Coarse Filtration: Removing Large Particles
At the front end of juice processing, the raw juice after pressing or pulping contains a large amount of coarse impurities – peel fragments, seeds, coarse fibre, etc. The Gaofu fruit juice rotary vibrating sieve can be configured with coarser mesh screens (e.g., 20 to 60 mesh) to intercept large particles at the source. The coarse‑filtered juice provides clean material for subsequent fine filtration and sterilisation.
Fine Filtration: Improving Juice Clarity
After coarse filtration, the juice still contains fine fibres and suspended solids. By switching to finer mesh screens (e.g., 80 mesh, 120 mesh, 200 mesh), fine impurities can be further removed. After fine filtration, the juice is clear and bright, with a pure taste, and both product grade and shelf‑life stability are significantly improved.
Multi‑Deck Synergy: Coarse and Fine Filtration in a Single Pass
The multi‑deck screen configuration of the Gaofu fruit juice rotary vibrating sieve allows coarse and fine filtration to be completed simultaneously in the same machine. Taking a two‑deck configuration as an example: the top deck (coarser mesh) intercepts large peel and seed particles, while the bottom deck (finer mesh) removes fine fibres and suspended solids. One machine, one feed – coarse and fine filtration completed simultaneously – with no material transfer between equipment, reducing the risk of secondary contamination.
In actual production, a single S49 series rotary vibrating sieve can handle juice flow rates of up to 120 m³/hour. Taking citrus juice filtration as an example, coarse filtration uses a 20‑mesh screen, and fine filtration uses an 80‑mesh screen – efficiently completing the stepwise removal of everything from peel fragments to fine suspended solids.
Advantage 1: Anti‑Blinding Design – Solving the High‑Fibre Blinding Problem
To address the high‑viscosity and high‑fibre characteristics of fruit juice and pulp, the Gaofu fruit juice rotary vibrating sieve incorporates an anti‑blinding design with efficient cleaning devices. Food‑grade silicone balls placed under the screen deck continuously tap the underside of the screen during operation, dislodging fibre and pectin particles blocking the mesh openings. This cleaning method is continuous and automatic, requiring no manual intervention, effectively solving the common problem of traditional filters blinding and requiring frequent stoppages for cleaning.
Advantage 2: Food‑Grade Stainless Steel – Ensuring Food Safety
Juice is consumed directly, so the safety of equipment materials is non‑negotiable. All material‑contact parts of the Gaofu fruit juice rotary vibrating sieve are made of 304/316L food‑grade stainless steel , with finely polished internal and external surfaces, no hygiene dead corners, and easy to clean and sanitise. The equipment features a fully enclosed screening design , effectively preventing secondary contamination of the material and fully complying with food GMP standards and HACCP system requirements.
Advantage 3: High Throughput – Suited to Large‑Scale Production
The Gaofu fruit juice rotary vibrating sieve features large‑capacity inlet and outlet ports, with a processing capacity of 5 to 20 tonnes per hour. Multiple units can be connected in series or in parallel according to capacity requirements, directly integrated into the production line for continuous operation. The equipment has a compact footprint, taking up little floor space, and is suitable for fruit juice processing workshops of all scales.
Advantage 4: Quick Screen Changes – Reducing Downtime
The Gaofu S49 series rotary vibrating sieve uses a mother‑child screen frame structure , allowing screen changes in just 3 to 5 minutes. The mother screen provides structural support, while the fine screen (working screen) performs the screening. When the fine screen wears out or a different mesh size is needed, only the fine screen needs to be replaced; the mother screen can be used for a long time. This design reduces consumable screen costs while shortening production line downtime.
Advantage 5: 360° Adjustable Discharge Ports – Flexible Line Integration
The discharge ports of the rotary vibrating sieve can be rotated 360° around the axis, facilitating the arrangement of auxiliary equipment. Regardless of workshop layout, it can flexibly connect to upstream and downstream equipment, adapting to the installation requirements of different production lines.
The Gaofu S49 series fruit juice rotary vibrating sieve is suitable for the following juice and liquid food filtration applications:
Clear fruit juice filtration. Apple juice, grape juice, pomegranate juice and others – removing pulp fibres, pectin and fine suspended solids to ensure clear, bright juice. Coarse filtration uses 40‑60 mesh screens, fine filtration uses 100 mesh or finer screens, removing impurities stepwise.
Cloudy fruit juice filtration. Orange juice, mango juice, tomato juice and others – retaining some pulp while precisely controlling the particle size and proportion of pulp pieces, removing coarse fibres and hard particles while maintaining the right mouthfeel.
Fruit and vegetable blended juice filtration. Carrot juice, blended fruit and vegetable juices – multi‑deck screens complete staged filtration in a single pass.
Speciality juice filtration (e.g., sea buckthorn juice). After pulping, sea buckthorn juice undergoes separation filtration, homogenisation, and rotary vibrating screening to ensure uniform pulp consistency and complete impurity removal.
