Over 10,000+ customers' choice, Focus on screening industry 40+ years
The Gaofu compact benchtop food powder filtration sieve was designed from the outset with a clear positioning – a benchtop structure to meet the screening needs of laboratories and small production lines.
Unlike traditional industrial screening machines, this equipment features a compact vertical integrated structure with no protruding components, occupying far less floor space than square screening machines of similar capacity. The equipment can be placed directly on a laboratory bench or worktable, requiring no pre‑installed foundation – a flat surface is all that is needed. For laboratories, small workshops and pilot production lines, this flexible deployment completely solves the problem of "nowhere to put the equipment".
Model specifications suited to small‑batch scenarios. The equipment is available in a compact 600mm size, specifically designed for small food processing lines, R&D laboratories and quality inspection agencies. The whole unit is lightweight and fitted with shock‑absorbing springs at the base, allowing it to be moved and positioned as needed. A single machine meets the screening needs of both routine laboratory quality control and small‑batch production.
Although the Gaofu compact benchtop food powder 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 material 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 food powder screening requirements.
The advantages of this three‑dimensional motion for food powder screening are:
First, thorough material loosening. Food powders such as milk powder, starch and sugar powder continuously tumble and disperse under three‑dimensional vibration, and slight lumps are naturally broken apart during the motion without additional intervention.
Second, thorough screening with high accuracy. The material travels along a spiral trajectory, giving every particle multiple opportunities to contact the screen. Screening accuracy can reach up to 500 mesh and filtration precision down to 5 microns. Whether it is the fineness determination of flour or the fine classification of starch, it can be completed with precision.
Third, suitable for both dry and wet materials. The equipment is not only suitable for dry powder screening but also for the filtration of slurry‑type materials. The determination of solids content in liquid samples such as fruit juices and seasoning slurries, commonly encountered in laboratories, can also be completed on the same machine.
1. Benchtop Structure – Saves Space
The compact structure allows the equipment to be placed directly on a laboratory bench or worktable. Fitted with shock‑absorbing springs, it runs smoothly without requiring a fixed position. For laboratories and small workshops with limited space, this design means the equipment can be deployed flexibly without needing to reconfigure the workshop layout for a single screening machine.
2. Food‑Grade Stainless Steel – Ensures Food Safety
Food powders are directly related to food safety, so equipment material quality is non‑negotiable. All material‑contact parts of the Gaofu compact benchtop food powder filtration sieve are made of food‑grade 304 stainless steel, with finely polished surfaces, no hygiene dead corners, and easy to clean. For laboratories or production lines requiring even higher cleanliness, higher‑specification stainless steel is also available. The equipment complies with food GMP requirements.
3. Multi‑Deck Classification – Multi‑Fraction Data from a Single Screening
The equipment supports 1 to 5 screen decks, allowing a single feed to obtain particle size distribution data for multiple fractions simultaneously. In a two‑deck configuration, for example: the top deck retains coarse particles and foreign matter, the bottom deck removes ultra‑fine powder, and the middle deck collects the target‑size sample. For laboratories that need to determine powder fineness in accordance with national standards, a single screening provides complete particle size distribution data.
4. Quick Screen Change – Adapting to Multi‑Variety Changeovers
The characteristic of laboratories and small production lines is many varieties, small batch sizes, and frequent changes. The Gaofu compact benchtop food powder filtration 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 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 costs while greatly shortening downtime for product changes.
5. Fully Enclosed Structure – Dust, Moisture and Contamination Protection
During food powder screening, dust escape causes both sample loss and laboratory contamination. The Gaofu compact benchtop food powder filtration sieve has a fully enclosed sealed structure, with screening taking place inside a sealed chamber – no powder escape, no sample leakage. The fully enclosed design also effectively blocks external moisture, preventing secondary moisture absorption of the food powder during screening.
6. Automatic Discharge of Impurities – Simple Operation
During screening, impurities and oversize material automatically move along the screen surface to the reject port and are discharged. The operator simply feeds the sample into the inlet and starts the machine – no frequent intervention, no manual cleaning of the screen surface. Operation is simple and does not require specialist technical skills.
Food R&D laboratories. Raw material inspection and sample particle size analysis during new product development. Determination of particle size distribution of food powders such as flour, milk powder, protein powder and starch.
Small food processing plants. Raw material impurity removal and finished product inspection in small‑batch production. Removing lumps and foreign matter from sugar powder, seasoning powders, rice flour and other materials.
Quality inspection agencies and third‑party testing. Determination of fineness of powder foods in accordance with national standards such as GB/T 5507‑2008 "Inspection of Grain and Oils – Determination of Fineness of Powdered Products". The equipment can be used with standard test sieves to ensure the standardisation and repeatability of test results.
Bakery shops and small workshops. On‑site screening and impurity removal of baking ingredients such as flour and sugar powder, ensuring the raw materials are fine and uniform.
