Protein powder is an ultra‑fine powder (whey protein powder can have a particle fineness of up to 43 microns) with low bulk density. During traditional open bag‑opening and feeding, it readily generates dust. Dust not only pollutes the workshop environment and endangers operator health but can also migrate to other clean areas, causing cross‑contamination.
The dust‑free operation of Gaofu's protein powder feeding system begins with the dust‑free feeding station. Operators complete bag opening and tipping on an enclosed feeding platform that maintains a micro‑negative pressure during operation – under the action of the exhaust fan, negative pressure is created inside the working chamber, directionally drawing dust generated during feeding into the filtration system and preventing it from escaping outside the cabinet. The dust collection fan prevents material dust from dispersing during bag opening.
The feeding platform operates under negative pressure – no dust leakage, no material loss during feeding – protecting the clean environment. At the same time, the dust‑free feeding station integrates a vibrating screening system (safety screen) – as material is fed, it passes through the screen to intercept packaging debris, thread impurities, and lumped material, ensuring only合格 material proceeds to the next process. This "feeding‑and‑screening‑in‑one" design ensures protein powder purity at the source.
After feeding is completed, protein powder enters the conveying stage. In traditional open conveying methods, material is exposed to the workshop environment multiple times during transfer, increasing the risks of dust contamination and foreign matter intrusion.
Gaofu's feeding system uses fully enclosed pneumatic conveying design – raw materials never contact air or personnel from feeding through conveying. The system uses negative‑pressure vacuum conveying for rapid material transfer, and positive‑pressure conveying combined with high‑precision weighing sensors for precise metering. The entire conveying process takes place in enclosed piping – the internal surfaces of conveying pipes are mirror‑polished, with no dead corners and minimal material residue.
The value of fully enclosed conveying is systematic:
Eliminating dust emission. The system completely eliminates material "spillage, leakage, emission, and drip" during feeding and conveying – effectively controlling workshop dust concentration to ≤10 mg/m³ , complying with the requirements of the General Hygiene Standard for Food Production (GB 14881‑2013). For sports nutrition plants seeking GMP, FDA, and other certifications, this dust control level means the feeding area can meet stringent production standards.
Preventing cross‑contamination. Protein powder production workshops typically handle multiple product varieties – whey protein, soy protein, pea protein, collagen, and more – with frequent changeovers. The fully enclosed conveying system keeps different materials flowing in their own enclosed piping, physically preventing cross‑contamination.
No raw material exposure, no secondary contamination – fully compliant with food production hygiene standards.
Protein powder is a high‑value material – batching accuracy directly determines product quality stability. In traditional manual weighing modes, operators are affected by fatigue and operational habits – metering errors are difficult to control, and batch‑to‑batch quality fluctuations have long been a "headache" for production management.
The precise metering capability of Gaofu's feeding system comes from the coordinated operation of PLC control modules and high‑precision sensors. The system monitors powder flow in real time, keeping metering errors within minimal ranges.
Dedicated automatic metering modules for powdered materials like protein powder achieve metering accuracy errors of ≤±0.5%. For medium‑to‑large batches, batching accuracy can reach ±0.2% ; for small batches, errors are ≤±0.1% ; for micro‑additives, accuracy can be as low as ±0.05%.
The system supports multiple batching methods – gain‑in‑weight, loss‑in‑weight, dynamic multi‑component, and others – flexibly selectable according to production process requirements. The online weighing hopper enables dynamic metering – precise metering is the core prerequisite for ensuring uniform and stable product quality.
Through high‑precision sensors and AI learning calibration programmes , the system recalibrates metering parameters in real time – ensuring every batch of raw materials is precisely proportioned. This means every batch maintains consistent formulation – protecting product quality stability at the source.
The intelligence of the protein powder feeding system is reflected not only in metering accuracy but also in its full‑process coordinated control capability.
The system incorporates an intelligent coordinated control module – protein powder, sugar powder, oil, water, and other ingredients are automatically fed at the right rate according to the process sequence, without manual intervention, achieving seamless "feeding‑screening‑conveying‑metering" operation. Automated feeding is 3‑5 times faster than manual operation, increasing single‑line capacity by over 30%. One system can replace 3‑5 workers – no manual handling, weighing, or dumping of ingredients – significantly reducing labour and management costs.
The system is equipped with a touchscreen interface – multiple recipes can be preset, and the feeding process can be started with one touch. Managers can monitor key information in real time – material inventory, feed rate, metering data – at a glance. The system supports multiple preset recipes – one‑touch product changeovers – reducing changeover time from several hours in traditional mode to 15 minutes. At the same time, the system supports integration with MES information systems – raw material usage data is uploaded in real time for digital management.
The system's core equipment has passed national explosion‑proof (CNEX) certification. For environments with conductive dust, anti‑static filter elements with proper grounding can be selected – reducing the risk of static charge accumulation on dust.
