First, why food and pharmaceutical companies must use flexible conveying line?
Lessons from a beverage factory in Xuhui District: When the production line was upgraded in 2024, three major pain points were encountered due to the use of traditional metal roller conveyor belts:

- clean a dead end: Lubricating grease seeped into conveyor belt seams, resulting in three microbiological exceedances on the bottling line and a shutdown and rectification loss of over $800,000;
- Productivity change inefficiencies: Adjusting bottle shape required dismantling the entire conveyor, which took 2.5 hours each time and delayed order delivery;
- squandering of space: The linear layout occupies 300 square metres and cannot be adapted to the plant's spiral lifting needs.
The Breakthrough Value of Flexible Conveyor Lines: After the plant's replacement with a modular chain link line:

- Cleaning Efficiency Improvement 40%: Food grade PP chain plate is directly water flushed, no oil residue, passed FDA flight inspection;
- Reduction of labour exchange to 15 minutesQuick release links support bottle switching and are compatible with 200ml-1L packages;
- Saving of 30% plant area: Spiral climb design utilises vertical space to free up 100m2 of storage area.
Essential Industry Needs: Flexible conveyor lines are not "optional", they areGMP-certified equipment--Its lubrication-free, bendable, and quick-adjusting characteristics directly address food and pharmaceuticalcontamination risktogether withflexible productionContradiction.
Second, the industry-specific needs dismantling: selection to avoid the pit guide
Hygiene Compliance: Tougher Than Cleanliness
- Material Selection::
✅Stainless steel chain plate: Preferred by Xuhui Biopharmaceuticals, resistant to strong acid disinfectants (e.g. sodium hypochlorite);
❌ 普通工程塑料:长期接触75%酒精易脆化,某试剂厂因此链板断裂停产。 - structural design::
- Seamless links(e.g. Flexlink Steel Top Chain): Avoids dirt pick-up and reduces cleaning time by 251 TP3T compared to seam type;
- Tiltable side panels: Facilitating deep cleaning of dead spots, weekly maintenance time at a dairy plant was reduced from 4 hours to 1 hour.
Temperature control scenarios: the balance between cold chain and autoclaving
take | programme | Xuhui Case |
---|---|---|
-40°C freezer | POM material + anti-freeze bearing | A prefabricated vegetable enterprise -25 ℃ environment operation for 3 years without failure |
80°C Cooking Line | Heat-resistant stainless steel + heat-resistant seals | Sauce filling line for condiment factory, resistant to 100°C steam |
high humidity environment | IP69K protection motor | 0 faults recorded in the washdown area of the healthcare workshop |
Space optimisation: "snail's nest" for small factories
The cost of land in Xuhui District exceeds RMB 60,000 per square metre, and the flexible conveyor line breaks through three layouts:
- spiral tower: A capsule factory achieved a 10m vertical lift in a 5m diameter space, saving 80% of horizontal access;
- S-barrier: Bypassing aseptic plant load-bearing columns to avoid production line interruptions;
- multilayer reflux: Packing line and filling line stacked up and down, logistics efficiency increased by 50%.
III. Field cases in Xuhui District: the full path from failure to success
Case 1: The life and death of GMP certification for pharmaceutical companies
sore point: An innovative drug company was issued 483 defective items in an FDA inspection due to contamination of a conveyor belt lubricant.
prescription::
- Replace withLubrication-free Flexlink systemChainplates are ISO 15378 certified;
- retrofittingOnline Particle Monitor, real-time feedback on cleanliness;
- Slope Drainage Design: Eliminate stagnant water that harbours micro-organisms.
in the end: 0 contamination record through EU GMP audit, capacity increase of 200%.
Case 2: Intelligent upgrade of a beverage factory
original dilemma: Traditional production line sorting error rate of 8%, annual loss of more than 1.2 million.
Flexible chain line + AI transformation::
- Dynamic weighing modules: Rejects underfilled products with 99.2% accuracy;
- Visual inspection station: Automatic identification of bottle cap defects, defective product interception rate of 100%;
- IoT predictive maintenance: 2 weeks advance warning of chain link wear and zeroing in on faulty stops.
Case 3: Micro conveyor systems in biological laboratories
Requirements of a cell therapy company in Xuhui: conveying culture bottles in a 50m2 clean room.Zero vibration, zero static.
Tailor-made solutions::
- Magnetic Levitation Drive Chain: Operating noise <25dB to avoid vibration affecting cell activity;
- Carbon Fibre Conductive Chain Plate: Surface resistance <10⁶Ω prevents electrostatic adsorption of particles;
- Embedded Sensors: Real-time monitoring of temperature/humidity/particle count, with direct data flow to the regulatory platform.
IV. Selection guide: four steps to lock the optimal programme
Step 1: Matching Material Characteristics
Material Type | Recommended Chainplates | contraindication (medicine) |
---|---|---|
Liquid bottles/cans | Flat chain with stopper | Mesh chain (risk of stuck bottles) |
Tablets/capsules | Anti-static ball chain | Inclined chain (risk of tipping) |
flexible packaging bag | Double Chain Clamping Conveyor Line | Roller lines (risk of slippage) |
Step 2: Quantify performance parameters
- Conveying speed: The filling line needs to be ≥15m/min, and the sorting line needs to match the robotic beat (e.g. 30 pieces/min);
- load-bearing limit: Choose a heavy-duty chain (e.g. CH103 chain) for infeed canisters ≥ 50 kg/m and a light-duty chain (e.g. CL63 chain) for reagent bottles;
- turning radius: R150mm miniature bends (e.g. Flexlink system) are preferred for small workshops.
Step 3: Intelligent function pre-built
mandatory module::
- Manipulator InterfaceEtherCAT communication ports are reserved to support future automation expansion;
- Data Centre Docking: Open OPC UA protocol for digital twins on the production line;
- Energy consumption monitoringA pharmaceutical company saves 180,000 yuan in electricity costs per year by displaying the power consumption of a single metre of conveyor in real time.

V. Future trends: from "conveyor" to "intelligent logistics hub"
Xuhui head pharmaceutical companies have practisedFlexible chainplates + digital twins::

- Real-time dynamic optimisation: AI automatically adjusts the conveyor path according to the order priority, and the line utilisation rate is from 68% → 92%;
- blockchain traceability: Uploading the delivery track of each batch of medicines, increasing the efficiency of regulatory audits by 5 times;
- Low carbon design: Solar chain plate drive (e.g. Weaving Knowledge Intelligence programme), 12 tonnes of carbon reduction per year on a single line.
personal viewpoint: The ultimate value of a flexible conveyor line is not in the hardware itself, but in theReconfiguring the production logic--It allows food and pharmaceutical companies to move from "rigid batch" to "flexible customisation" over the next three years.Self-learning conveyor systemThe current 80% fixed production line will be phased out, and devices without pre-built AI interfaces will be relegated to sunk costs.
