Bottle Warming Tunnel
TUYAO Bottle Warming Tunnel serves as key auxiliary equipment for carbonated and sparkling beverage production lines. Equipped with a multi-zone gradient warm water spraying system, it evenly warms chilled bottles up to ambient temperature to remove surface condensation. The machine prevents label wrinkling, unclear inkjet coding and damp packaging, and works seamlessly with filling lines for PET bottles, glass bottles and cans.

Product Overview
The bottle warming tunnel is a spray-type warming machine developed to meet diverse production demands for beverage manufacturers. Widely deployed on beverage bottling lines, it processes filled bottles after the filling procedure. Without altering the color, aroma, flavor or nutritional properties of beverages, the equipment raises bottle temperature to narrow the temperature difference between filled beverages and ambient air. It eliminates condensation on the outer surface of bottles, creating ideal conditions for labeling and enabling clean, dry carton packing. Our bottle warming tunnel works perfectly with automatic labeling machines to remove bottle condensation and improve labeling effect.

Main Features
● The machine body is constructed of stainless steel (excluding motors, bearings). Observation windows can be installed on the side frame, and the top structure is openable for convenient maintenance.
● The water collection tank inside the tunnel is fitted with a circulating filtration device and alarm system.
● The slat chain adopts heat-resistant flat top mesh, featuring excellent wear resistance.
● A main drive overload protection device is installed to effectively safeguard the slat chain and conveying system.
● Equipped with thermometers and water pressure gauges.
● Comes complete with spray circulation water pumps and dosing pumps for sanitizer.
● The segmented spray pipelines are detachable for simple cleaning.
● Uniform supplementary spraying is adopted in the first heating zone to avoid sharp fluctuations in water temperature.
Process Characteristics
1. Bottles or cans requiring temperature rise are conveyed by the inlet conveyor onto the mesh chain via plastic transition plates. Containers are automatically aligned before entering the heating zone.
2. Circulating water is heated to the set temperature by a plate heat exchanger, then delivered by circulation pumps to nozzles mounted above the mesh chain. Water is evenly sprayed onto bottles and cans to heat the containers.
3. The warm water flows through the mesh chain into the lower water tank, reheated to the target temperature, and recirculated by pumps for repeated use.

FAQ
Q1: Are you a trading company or a direct manufacturer?
A: We are a dedicated manufacturer with over 22 years of industry experience in beverage filling and packaging. Based in Zhangjiagang (only 2 hours from Shanghai), our factory is equipped with advanced technology to provide high-quality equipment at factory-direct prices. We warmly welcome you to visit our facility to see our machines in action.
Q2: Why do beverage lines need a bottle warming tunnel?
A: Low-temperature bottles produce condensation when meeting room-temperature air. Water droplets will make adhesive labels unable to stick firmly. The warming tunnel heats bottles to remove condensation and guarantee high labeling quality.
Q3: Can this warming tunnel connect directly to my existing bottling line?
A: Yes. We adopt universal conveying standards. We can adjust the inlet and outlet height, conveyor width according to your current filling machine and labeling machine to achieve seamless connection.
Q4: Do you provide overseas installation and training?
A: Yes. We can arrange senior technicians to your factory for installation, commissioning and systematic operation & maintenance training, including bottle blowing process adjustment and common fault handling.
Q5: What is the warranty period?
A: We provide a 12-month whole machine warranty starting from the commissioning date, with lifetime technical support and long-term supply of original spare parts and wearing parts at factory price.
