In beverage R&D laboratories, sample filtration of fruit juice is a seemingly simple but critically important step.
The development of a new beverage often requires dozens or even hundreds of formula adjustments – from selecting fruit varieties to fine‑tuning sugar‑acid ratios, from determining pulp content to controlling clarity. After each adjustment, the sample must be filtered to evaluate taste, colour and stability under different parameters.
However, R&D scenarios are fundamentally different from production scenarios. Small batches, high frequency and rapid changeovers – the requirements for laboratory filtration equipment are completely different from those of large‑scale production lines. Large industrial filtration machines are bulky and complicated to operate; using them for sample volumes of a few dozen millilitres to a few litres is overkill. Manual sieve filtration, while simple, is inefficient and poorly reproducible, failing to meet the accuracy and repeatability requirements of R&D work.
The Gaofu compact vertical fruit juice filtration sieve is a specialised tool designed specifically for this scenario in beverage R&D laboratories. With its compact vertical structure fitting limited laboratory bench space, three‑dimensional vibration for filtration accuracy, and food‑grade stainless steel for hygiene, it provides R&D personnel with a precise and efficient sample filtration solution.
The Gaofu compact vertical fruit juice filtration sieve was designed from the outset with a clear positioning – a vertical compact structure to meet the sample filtration needs of laboratories.
Unlike traditional industrial screening machines, this equipment features a vertical integrated design with moderate height and a small footprint. It can be placed directly on a laboratory bench or worktable without requiring a pre‑installed foundation. The vertical structure allows material to pass through from top to bottom under the combined action of gravity and vibration, with a short path and high efficiency – particularly suitable for rapid processing of small samples.
The equipment is lightweight and fitted with shock‑absorbing devices at the base, ensuring stable operation and allowing it to be moved as needed. For R&D laboratories with limited space, this flexible deployment completely solves the problem of "nowhere to put the equipment". The unit is available in a compact S49‑400 model with an effective screen diameter of 340 mm, specifically designed for laboratory sample filtration and small‑batch R&D scenarios.
Although the Gaofu compact vertical fruit juice filtration sieve is small in size, its screening principle is the same as that of large industrial rotary vibrating sieves – it also uses three‑dimensional vibration technology.
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. When the motor rotates, the weights convert the rotational motion into compound vibration in horizontal, vertical and tilting directions, which is transmitted to the screen deck, causing the liquid to move in a spiral outward trajectory. By adjusting the phase angle of the upper and lower eccentric weights, the motion trajectory and residence time of the material on the screen surface can be flexibly changed to suit different juice sample filtration requirements.
The advantages of this three‑dimensional motion for juice sample filtration are:
First, rapid passage of liquid through the screen. Under three‑dimensional vibration, the 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 and peel fragments 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, thorough filtration with high accuracy. The liquid travels along a spiral trajectory, giving every drop multiple opportunities to contact the screen. Screening accuracy can reach up to 600 mesh (0.02 mm) and filtration precision down to 5 microns.
Third, suitable for both liquid and powder materials. The equipment is suitable not only for filtration of liquid samples such as fruit juice and puree, but also for screening of powder materials (e.g., sugar powder, milk powder, seasoning powders). Various common sample types in the laboratory can be processed on the same machine.
Core Advantages: Designed for R&D Laboratories
Vertical Compact Structure – Does Not Occupy Bench Space
The equipment features a vertical integrated design with moderate height and can be placed directly on a laboratory bench or worktable. Fitted with shock‑absorbing devices, it runs smoothly without requiring a fixed position. For R&D laboratories with limited space, this design means the equipment can be deployed flexibly without needing to reconfigure the laboratory layout for a single filtration machine.
Food‑Grade Stainless Steel – Ensuring Sample Safety
Juice samples are used directly for formula evaluation and taste testing, so the safety of equipment materials is non‑negotiable. All material‑contact parts of the Gaofu compact vertical fruit juice filtration sieve are made of food‑grade 304 stainless steel, with finely polished surfaces, no hygiene dead corners, and easy to clean. The equipment complies with food contact material hygiene standards, ensuring the purity of every sample batch.
High Filtration Accuracy – Meeting Diverse R&D Needs
Different juice products require different filtration accuracy – clear juices need removal of fine suspended solids, while cloudy juices require precise control of pulp particle size. The Gaofu compact vertical fruit juice filtration sieve supports single‑deck or multi‑deck screen configurations, allowing flexible selection of mesh sizes according to the process requirements of different samples. Filtration precision can reach 5 microns, from coarse filtration (removing peel and seeds) to fine filtration (removing coarse fibres and fine suspended solids) – all completed on one machine.
Simple Operation, Quick Changeovers
R&D work is characterised by many varieties, small batch sizes, and frequent changes. The Gaofu compact vertical fruit juice filtration sieve is simple to operate and does not require special training. Screen changes take only 3 to 5 minutes – the mother screen provides structural support, while the fine screen (working screen) performs the filtration. When 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 greatly shortens changeover time between different samples, improving R&D efficiency.
Fully Enclosed Structure – Dust, Splash and Contamination Protection
During sample filtration, liquid splashing causes both sample loss and potential contamination of the laboratory environment. The Gaofu compact vertical fruit juice filtration sieve has a fully enclosed sealed structure, with filtration taking place inside a sealed chamber – no splashing, no sample leakage. The fully enclosed design also effectively blocks external foreign matter, ensuring sample purity.
Low‑Noise Operation – Suitable for Laboratory Environments
Laboratories have strict requirements for noise levels. The Gaofu compact vertical fruit juice filtration sieve operates with low noise and will not interfere with normal laboratory work. The equipment runs smoothly, requires no complex installation, and is ready for use when connected to a power supply.
