In the production of fruit juices, purees and jams, filtration and screening are the critical steps that determine product clarity, mouthfeel and quality. A high‑quality fruit juice, from pressing to filling, requires careful treatment through multiple processes. The most critical of these is filtration – effectively separating solid impurities such as fruit pulp fibres, peel fragments, seed pieces and hard fruit particles from the juice.
Whether it is clear juice (apple juice, grape juice), cloudy juice (orange juice, mango juice), or beverages containing pulp and fruit pieces, the accuracy of the filtration step directly affects the quality of the final product.
However, fruit juice filtration in actual production faces three practical challenges:
Challenge 1: Screen blinding reduces production efficiency. Fruit puree contains large amounts of fibre and pectin, making it viscous and prone to blinding the screen. After traditional filtration equipment runs for several hours, screening efficiency drops noticeably, requiring frequent stoppages for cleaning and seriously affecting continuous production.
Challenge 2: Filtration accuracy is difficult to control. It is necessary to effectively remove pulp fibres and impurities while retaining the nutritional components of the juice, avoiding over‑filtration that would cause flavour loss and raw material waste. For beverages containing fruit pulp, the particle size and proportion of pulp pieces must also be precisely controlled.
Challenge 3: High hygiene standards. Juice is a beverage consumed directly, so equipment must have no hygiene dead corners, be easy to clean, comply with food production GMP standards, and eliminate the risk of microbial contamination.
The Gaofu S49 series fruit juice rotary vibrating sieve is a liquid screening machine specifically designed to address these challenges. It achieves efficient solid‑liquid separation through three‑dimensional vibration, ensures hygiene safety with food‑grade stainless steel, and solves the screening difficulties of high‑fibre, high‑viscosity materials with an anti‑blinding design.
The Gaofu S49 series fruit juice rotary vibrating sieve uses a vertical vibration motor as the excitation source. Eccentric weights installed at the upper and lower ends of the motor shaft convert the rotational motion into a horizontal, vertical and tilting three‑dimensional compound motion – known as "three‑dimensional motion". This compound motion is transmitted to the screen deck, causing the liquid to move in a spiral outward trajectory on the screen surface.
For fruit juice filtration, this three‑dimensional motion offers three core advantages:
First, rapid passage of liquid through the screen. Under three‑dimensional vibration, the fruit juice forms a thin flowing layer on the screen surface. The liquid portion quickly passes through the screen, while solid impurities such as pulp fibres, peel fragments and seed pieces are retained on the screen surface. The high‑frequency, low‑amplitude vibration keeps the liquid in a fluidised state, avoiding the decline in filtration efficiency caused by liquid accumulation.
Second, automatic discharge of impurities. Solid impurities retained on the screen surface move along the screen surface under vibration and are automatically discharged from the reject port. The equipment can operate continuously without frequent stoppages for cleaning.
Third, high and adjustable filtration accuracy. The S49 series rotary vibrating sieve can achieve screening accuracy up to 600 mesh (0.02 mm) and filtration precision down to 5 microns. The equipment supports 1 to 5 screen decks, enabling simultaneous separation into 2 to 6 grades. From coarse filtration (removing peel, seeds and unbroken pulp pieces) to fine filtration (removing coarse fibres and fine suspended solids), the configuration can be flexibly adjusted according to the process requirements of different fruit juice products.
Core Technical Advantages of the Gaofu Fruit Juice Rotary Vibrating Sieve
1. Anti‑Blinding Design – Solving the High‑Fibre Blinding Problem
To address the high‑viscosity and high‑fibre characteristics of fruit juice and puree, the Gaofu fruit juice rotary vibrating sieve incorporates an anti‑blinding design with efficient cleaning devices.
The equipment is equipped with a bouncing ball cleaning system – food‑grade silicone balls are placed under the screen deck. During screening, the balls continuously tap the underside of the screen, 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.
For thicker purees or ultra‑fine filtration applications, an optional ultrasonic anti‑blinding system can be added, using high‑frequency vibration to break the adhesion between the material and the screen.
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 has a fully enclosed screening design, effectively preventing secondary contamination of the material, and fully complying with food production GMP standards and HACCP system requirements.
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.
4. Multi‑Deck Classification – One Machine, Multiple Uses
The Gaofu fruit juice rotary vibrating sieve supports single‑deck or multi‑deck configurations, meeting the differentiated filtration needs of various fruit juice products (clear juice, cloudy juice, puree).
In a three‑deck configuration, for example: the first deck removes large impurities such as peel, seeds and unbroken pulp pieces; the second deck performs fine filtration to remove coarse fibres and suspended solids; and the third deck enables classification screening – for manufacturers producing products of different particle sizes, this allows simultaneous production of both clear juice and beverages containing fruit pulp.
5. Automatic Discharge of Impurities – Continuous Operation
During screening, impurities and oversize material automatically move along the screen surface to the reject port and are discharged. The equipment can run 24 hours continuously without manual intervention, with a normal service life of 15 to 20 years.
6. Quick Screen Change – 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.
The Gaofu fruit juice rotary vibrating sieve is suitable for filtration of the following fruit juices and liquid foods:
Clear fruit juice filtration. Apple juice, grape juice, pomegranate juice and others – removing pulp fibres, pectin and fine suspended solids to ensure the juice is clear and bright.
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 fruit fragments while maintaining the right mouthfeel.
Fruit puree and jam filtration. Strawberry puree, mango puree, peach puree and others – separating fibres, removing peel fragments and hard particles.
Fruit and vegetable blended juice filtration. Carrot juice, blended fruit and vegetable juices – filtration of mixed raw materials.
Beverage industry. Tea beverages, plant‑based protein beverages, functional beverages – filtration and impurity removal.
