Tunnel Type Bottle Washing Machine

A Tunnel Type Bottle Washing Machine is a continuous, automated washing system designed for high-speed cleaning of glass, PET, or HDPE bottles in beverage, pharmaceutical, food, and brewing industries.

Bottle Washing Machine features a long, enclosed stainless-steel tunnel (typically 3–12 meters long) through which bottles are transported on a continuous conveyor belt or walking beam system. Bottles pass sequentially through multiple treatment zones inside the tunnel, ensuring thorough internal and external cleaning without manual intervention.

Key Features & Working Zones:

1. Pre-washing Zone – High-pressure water jets remove loose dirt, labels, and debris.

2. Pre-soaking/Detergent Zone – Bottles are soaked or sprayed with hot alkaline/caustic solution (60–85°C) to dissolve residues, glue, and organic matter.

3. Main Washing Zone – Intensive internal and external spraying with recycled or fresh caustic solution using dedicated nozzles for each bottle.

4. Rinsing Zones (Multiple stages)

   • Hot water rinsing

   • Fresh water rinsing

   • Final rinse with treated/DI water (for pharmaceuticals) or sterile water

5. Drip/Air Blowing Zone – Removes excess water using high-velocity air knives.

6. Optional Sterilization Zone – Hot water (≥85°C, steam, or chemical sanitization (for aseptic lines).

Advantages over Rotary Washers:

• Higher throughput and automation

• Smaller footprint for equivalent capacity

• Better suited for modern high-speed filling lines

• Lower water and energy consumption per bottle

Salient Features of Tunnel Type Bottle Washing Machine

• High-pressure spray nozzles ensure perfect wash of Bottles.

• Interchangeable wash sequences.

• Totally fabricated from SS Materials, including the basic frame.

• No change parts required for washing of round bottle saving time of change over. (Change Parts require for Flat bottles & if change of neck size.)

• All parts coming in contact with washing zones / jet are made from SS 316 materials.

• The machine suitable for handling washes of round and flat glass bottle (With help of change parts).

• Water re-cycling arrangement is possible as per customer’s need.

• Machine is totally rigid and withstands continuous operation for long working. Hours without any trouble.

• Higher capacity centrifugal pump to wash bigger container.

• Third Tank & pump can be fitted (optional).

Process Operation of Linear Bottle Washer

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.
