Over 10,000+ customers' choice, Focus on screening industry 40+ years
In traditional production models, feeding, screening, conveying, and batching often operate in isolation – after manual bag opening and feeding, material passes through a vibrating screen, then is manually carried or mechanically lifted to the next step. Each transfer between steps exposes material to the workshop environment multiple times, increasing dust dispersion opportunities and introducing foreign matter contamination risks.
Gaofu Machinery's whole‑line approach is fundamentally different: using the dust‑free feeding station as the system's starting point, seamlessly connected to downstream equipment through enclosed piping, achieving fully enclosed operation from feeding to production.
The value of this approach is that the feeding station is no longer an "island," but the first node of an automated production line. From the moment material enters the feeding station, it enters a closed processing flow – dust is collected in real time, impurities are screened online, and material is precisely delivered to buffer bins through enclosed piping – with no manual intervention and no foreign matter contamination risk.
Gaofu's dust‑free feeding station offers excellent expandability and can be paired with various downstream equipment to form a complete automated feeding system.
1. Integration with Vibrating Screening Equipment: Synchronised Feeding and Impurity Removal
Gaofu's dust‑free feeding station integrates a vibrating screening module (safety screen). As material is fed, it simultaneously passes through the screen – lumps are effectively broken, and foreign matter is reliably intercepted, ensuring that material entering the next process is pure and fine.
The significance of this "feeding‑and‑screening‑in‑one" design is merging two separate steps into one. In traditional mode, material must be fed, then transferred to a screener, then transferred to the next process – exposed to the workshop environment multiple times. The integrated design keeps material in an enclosed environment from feed inlet through screening, directly into conveying piping, with no external contact.
2. Integration with Pneumatic Conveying Systems: Enclosed Piping for Dust‑Free Transfer
Gaofu's dust‑free feeding station can be connected to positive‑ or negative‑pressure conveying systems for continuous material supply to the production line. After feeding and screening, material is delivered directly through enclosed piping to mixers, storage tanks, or the next process.
The value of pneumatic conveying is replacing manual handling with piping. Flour no longer needs to be manually carried, weighed, or dumped – it is automatically delivered to the target location through enclosed piping. The entire conveying process takes place in an enclosed environment, effectively preventing material exposure to air and reducing material loss and secondary contamination risks.
Gaofu's feeding system uses fully enclosed pneumatic conveying design – raw materials never contact air or personnel from feeding through 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).
3. Integration with Metering and Batching Systems: Precise Raw Material Ratio Control
For baking, pastry, and other food processing scenarios requiring precise batching, Gaofu's feeding system also integrates intelligent metering modules. For different material types – flour, sugar powder, oil, water – the system is equipped with dedicated automatic metering modules. Metering accuracy for flour and sugar powder can be controlled within ±0.5%, and for fluid ingredients such as oil and water within ±0.3%.
This means: from feeding to batching, the entire process is automated and precise. Operators no longer need to weigh materials manually – the system automatically completes metering and delivery according to preset recipes, ensuring product quality consistency while reducing human error.
4. Integration with Intelligent Control Systems: Full‑Process Visualisation and Monitoring
Gaofu's feeding system is equipped with a core process control and visualisation system. Through a touchscreen interface, operators can monitor key parameters in real time – material inventory, feed rate, metering data, equipment operating status – at a glance. The system supports multiple preset recipes, enabling one‑click product changeovers.
For production managers, this means complete visibility of the entire line's operating status. Which equipment is running, which bin needs refilling, what is the batching progress of each batch – all information is visible in real time, shifting production management from "experience‑based" to "data‑driven."
Gaofu's feeding system, through the coordinated integration of dust‑free feeding stations with downstream equipment, delivers quantifiable improvements for flour processing and food producers:
Efficiency improvement. Automated feeding is 3‑5 times faster than manual operation, increasing single‑line capacity by over 30%. One medium‑sized baked snack manufacturer, after introducing the system, needed only 3 operators to complete the feeding work that previously required 8 people – production efficiency increased by over 50%.
Cost reduction. The system can replace 3‑5 manual workers, significantly reducing labour and management costs. One medium‑sized bakery, after adopting Gaofu's flour dust‑free feeding system, saw annual raw material loss rates drop significantly, with total annual cost savings of RMB 3.6 million. Another baked snack manufacturer reduced raw material loss from 8% to below 3%, with annual cost savings exceeding RMB 1 million.
Quality stability. Fully enclosed operation effectively controls dust contamination and foreign matter risks. Precise metering and batching ensure consistent product composition batch after batch, fundamentally solving flavour inconsistency issues caused by inaccurate batching.
Compliance assurance. The system complies with the General Hygiene Standard for Food Production (GB 14881‑2013), helping companies confidently pass food safety inspections and environmental audits.
