Hangzhou GT Rail Traffic Equipment Co., Ltd

Application of Our Main Products in the Food Processing

Food processing—covering meat processing, dairy production, bakery operations, and beverage bottling—demands equipment that balances hygiene compliance, stable performance, and resistance to food-specific contaminants (e.g., moisture, oils, acidic ingredients). Even minor cross-contamination or operational errors can lead to product recalls, while downtime disrupts perishable food production schedules. Our portfolio of 42 specialized products is engineered to meet these strict requirements, powering critical processes from mixing and grinding to sorting and packaging. By integrating food-grade materials, easy-clean designs, and energy-efficient technology, our solutions help food processors maintain safety standards, reduce waste, and optimize productivity.

2. Competitive Advantages for Food Processing Applications

Our products solve four core challenges in food processing: hygiene compliance for safety, environmental resistance for durability, precision control for quality, and energy efficiency for cost savings.

2.1 Strict Hygiene Compliance (Meets Global Food Safety Standards)

  • Food-Grade Materials: All product contact parts use 304/316L stainless steel (resistant to corrosion from acidic/alkaline foods) and FDA-approved seals (e.g., EPDM gaskets), complying with 3-A Sanitary Standards and EU Regulation (EC) No. 1935/2004.

  • Easy-Clean Design: Smooth, crevice-free surfaces (Ra ≤0.8μm) prevent food residue buildup, while IP69K protection allows high-pressure, high-temperature washdowns (80℃, 100 bar)—critical for daily sanitation in meat/dairy plants.

  • No Cross-Contamination Risk: Sealed lubrication systems (with food-safe lubricants) prevent oil leakage into food products, eliminating contamination hazards in mixing and pumping processes.

2.2 Strong Resistance to Food Processing Environments

  • Moisture & Corrosion Resistance: Stainless steel construction and double-layer electrophoretic coating withstand constant exposure to water (e.g., vegetable washing lines) and acidic foods (e.g., tomato processing)—tested to 2,000 hours of salt spray without rust.

  • Temperature Tolerance: Motors and fans operate reliably in -20℃ (refrigerated warehouses) to 120℃ (bakery ovens), with thermal insulation to protect components from extreme heat in drying systems.

  • Oil & Grease Resistance: Specialized coatings on gear reducers and pumps repel food oils (e.g., in frying lines) and prevent grease buildup, reducing cleaning frequency by 50%.

2.3 Precision Control for Consistent Food Quality

  • Stable Speed Transmission: Gear reducers maintain ±0.5% speed accuracy, ensuring uniform mixing of dough (preventing over-mixing/under-mixing) and consistent conveyor speed for fruit sorting (reducing damage to delicate produce).

  • Accurate Fluid Dosing: Food-grade gear pumps deliver fluids with ±1% flow precision, ensuring exact syrup dosing in beverage filling or sauce application on ready meals—improving product consistency and reducing waste.

  • Smooth Operation: Low-pulsation pumps prevent foam formation in dairy transfer (critical for milk and cream products) and avoid pressure spikes that could damage fragile foods (e.g., soft fruits in washing lines).

2.4 Energy Efficiency & Low Maintenance for Cost Savings

  • High-Efficiency Motors: IE4-rated washdown motors reduce power consumption by 20–25% compared to standard motors—saving up to 1,000 kWh annually per dairy separator or flour mill.

  • Long Service Life: Sealed bearings and maintenance-free designs extend product lifespan to 18,000+ operating hours (60% longer than industry averages), reducing replacement costs for high-use equipment like mixers.

  • Minimal Downtime: Quick-disconnect designs for fans and pumps allow cleaning or replacement in 30 minutes (vs. 2 hours for standard models), critical for maintaining production schedules with perishable foods.


3. Proven Application Cases

Our products have been deployed in over 400 food processing facilities worldwide, spanning dairy, meat, bakery, and beverage industries.

4. Commitment to Sustainable Food Processing

We are dedicated to supporting the food industry’s shift toward safer, more sustainable production:

  • Eco-Friendly Manufacturing: 40% of raw materials use recycled stainless steel, reducing carbon emissions per unit by 32% compared to conventional production.

  • R&D for Food-Specific Needs: We invest 12% of annual revenue in developing ultra-hygienic products (e.g., oil-free gear reducers for clean-label food production) and energy-recuperation motors for high-energy processes like freezing.

  • Compliance Support: Our team provides documentation (material certificates, test reports) to help customers meet regional standards (FDA, EFSA, CFIA), simplifying regulatory audits.

By combining hygiene, durability, and efficiency, our products empower food processors to deliver safe, high-quality products while minimizing environmental impact and operational costs.
