Ice tea factory

A complete ice tea production line typically includes a water treatment system (RO), extraction/brewing tanks, blending and mixing systems, UHT (Ultra-High Temperature) sterilization, and automated filling and packaging machinery. For high-quality output, ensure the extraction system uses low-temperature vacuum extraction to preserve the tea's natural aroma and polyphenols.

Suppliers must adhere to food-grade stainless steel standards (SUS304 or SUS316L) for all contact surfaces. Key certifications include CE (Conformité Européenne) for machinery safety, ISO 22000 or HACCP for food safety management systems, and UL/CSA if the equipment is destined for the North American market to ensure electrical compliance.

Prioritize systems with heat recovery modules in the UHT stage, which can reduce energy consumption by up to 20-30%. Evaluate the Total Cost of Ownership (TCO) by factoring in the automation level; higher initial investment in PLC-controlled systems (like Siemens or Mitsubishi) significantly reduces long-term labor costs and minimizes product wastage due to human error.

Decide between Hot Filling (85-92°C) and Aseptic Cold Filling. Hot filling is more cost-effective for equipment but requires heat-resistant PET bottles, whereas Aseptic Cold Filling preserves better flavor and allows for thinner, cheaper bottles, though the initial machinery cost is higher. Ensure the capping machine has a rejection rate of <0.01%.

Always mandate a Pre-Shipment Inspection (PSI) by a third-party agency like SGS or TÜV. For large-scale factory lines, include a Fat (Factory Acceptance Test) clause in the contract, requiring the supplier to run the full line with your specific raw materials before final payment and shipping.

Focus on the warranty period and spare parts package rather than just the unit price. Negotiate for a 2-year warranty and a 'wear-and-tear' parts kit for the first 12 months of operation. Request on-site installation and staff training to be included in the FOB/CIF price to ensure a smooth transition to production.

Industrial lines require Open Top (OT) or Flat Rack (FR) containers for oversized components. Ensure the supplier uses vacuum-sealed moisture-proof packaging and heavy-duty wooden crates to prevent corrosion during sea transit. Verify that the supplier provides detailed layout drawings and electrical diagrams in English to facilitate local customs clearance and installation.

Utilize secure payment methods such as Letters of Credit (L/C) or escrow services provided by reputable platforms like Made-in-China.com. Avoid 100% upfront payments; a standard structure is 30% deposit, 60% after successful FAT, and 10% after installation and commissioning at your facility.
