Tunnel Type Bottle Washing Machine
Description
Tunnel Type Bottle Washing Machine is a fully automated, continuous washing system designed for high-speed and efficient cleaning of glass, PET, and HDPE bottles. Ideal for large-scale production, this industrial tunnel bottle washer is widely used in the beverage, pharmaceutical, food, brewery, and cosmetic industries.
This advanced bottle washing machine features a long enclosed stainless-steel tunnel (typically 3 to 12 meters in length) where bottles are transported on a continuous conveyor or walking beam system. As bottles move through multiple sequential treatment zones — including pre-rinsing, detergent washing, hot water rinsing, and final air blowing — they receive thorough internal and external cleaning without any manual intervention.
Engineered for maximum hygiene and operational efficiency, the Tunnel Type Bottle Washing Machine ensures consistent, high-quality cleaning results while significantly reducing labor costs and increasing production output. Its robust stainless-steel construction and reliable performance make it the preferred choice for manufacturers seeking GMP-compliant, high-throughput bottle cleaning solutions.

Working Principle of Tunnel Type Bottle Washing Machine
Three-cycle rinsing allows flexibilities of various wash cycles such as fresh water, dematerialized water etc. as per the rinsing requirement of bottle. All the pumps are made of SS and all the water contact parts are made of SS 316 on a heavy base of SS structure. In tunnel design is such that separation is maintained between feeding zone and discharge zone of the cleaned containers. All the mechanical drives are separated and isolated from the washing zone. Approved materials only are used for construction, together with a careful choice of components, thereby taking into consideration all aspects of sanitation and consequence complying with the pharmaceutical G.M.P. requirements. The quality of rinsing is ensured through 3 sets of inner and 2 sets of outer nozzles accurately placed to direct the jet at center of the bottle and the bottle comes out with water totally drained with minimum droplets of water.
- Infeed: Bottles are loaded via conveyor and inverted for gravity-assisted cleaning.
- Washing Cycle: High-pressure jets (caustic solution, sanitizer, or water) impinge on bottle interiors while bottles rotate. External sprays handle the outside.
- Rinsing and Drying: Followed by pure water rinse and air blow-off to remove moisture.
- Discharge: Clean bottles exit to the filling line, with recovery basins recycling fluids for sustainability.

Key Features of Tunnel Type Bottle Washing Machine
- Pre-washing Zone – High-pressure water jets remove loose dirt, labels, and debris.
- Pre-soaking/Detergent Zone – Bottles are soaked or sprayed with hot alkaline/caustic solution (60–85°C) to dissolve residues, glue, and organic matter.
- Main Washing Zone – Intensive internal and external spraying with recycled or fresh caustic solution using dedicated nozzles for each bottle.
- Rinsing Zones (Multiple stages)
- Hot water rinsing
- Fresh water rinsing
- Final rinse with treated/DI water (for pharmaceuticals) or sterile water
- Drip/Air Blowing Zone – Removes excess water using high-velocity air knives.
- Optional Sterilization Zone – Hot water (≥85°C, steam, or chemical sanitization (for aseptic lines).
