Machine overview
Linear Tunnel Bottle Washing Machine Manufacturer in India
H M Pharma Machines manufactures the Linear Tunnel Type Bottle Washing Machine in Ahmedabad, Gujarat, India for pharmaceutical and beverage bottle lines. The machine is configured for approved glass, PET, HDPE and PP bottle formats from 50 mL to 1 L. A wire-woven infeed belt transfers bottles toward the handling system, while mechanical cams load and unload them from HDPE pockets.
The HMLBWM series is available in four rated output configurations: HMLBWM-120 at 120 BPM, HMLBWM-150 at 150 BPM, HMLBWM-180 at 180 BPM and HMLBWM-240 at 240 BPM. BPM means bottles per minute.
The internal cycle follows five defined positions: compressed air, recirculated water, compressed air, fresh Purified Water and compressed air. Two external stages apply recirculated water followed by compressed air. Two SS 316 tanks, two 1 HP pumps, Code 7 filtration, pressure transmitters and process interlocks support the approved washing arrangement.

Bottle handling process
How the Linear Tunnel Bottle Washing Machine Works
The machine moves approved bottle formats through four controlled handling phases.
Wire-Woven Belt Infeed
The infeed belt transfers approved bottle formats toward the machine handling system.
Cam Loading into Pockets
Mechanical cams load the bottles into HDPE pockets for controlled linear movement.
Internal & External Washing
The pockets carry bottles through five internal wash positions and two external wash stages.
Cam Unloading & Transfer
Mechanical cams unload washed bottles through the outfeed prism and pusher toward the tunnel-conveyor interface.
Exact wash cycle
Five-Position Internal Bottle Washing Sequence
The internal sequence combines compressed air, recirculated water and fresh Purified Water in the confirmed order.
Compressed Air
Initial internal air stage.
Recirculated Water
Internal RC-water wash.
Compressed Air
Air stage after the RC-water wash.
Fresh PW
Fresh Purified Water wash.
Compressed Air
Final internal air stage.
Confirmed sequence: compressed air → recirculated water → compressed air → fresh Purified Water → compressed air. RC means recirculated water and PW means Purified Water.
External washing: two defined stages clean the bottle exterior in the sequence shown below.
External Stage 01 — RC Water
Recirculated water is applied to the bottle exterior.
External Stage 02 — Compressed Air
Compressed air follows the external RC-water wash.

Filtration & process supply
Defined Water, Air, Tank and Piping System
Two Process Tanks & Pumps
Two SS 316 storage tanks of 40 L each separately serve RC water and PW. Two 1 HP pumps with SS 316 contact surfaces support the approved process arrangement.
Code 7 Filtration
- Recirculated water: 10 micron
- Purified Water: 5 micron
- Compressed air: 0.2 micron
Project-Defined Process Piping
Process-piping material, joining method and finish are finalized in the approved order.
Project Documentation
DQ, IQ, OQ, PQ, FAT, SAT, HMI and Operation Manuals, serial-matched component certificates, the wiring diagram and machine layout can be included as defined in the approved order scope.
Process alarms & interlocks
Automatic Protection for Bottle Flow, Water, Air and Drives
The following responses reflect the confirmed machine scope; final alarm philosophy is documented in the approved control specification.
Low Bottle Level at Infeed
Low bottle level at the infeed stops the machine.
Low Water / Air Pressure
Pressure transmitters monitor RC-water, PW and compressed-air pressure. Low pressure in any required utility generates an alarm and stops the machine automatically.
Tank-Level Alarm
High and low water levels in the tanks generate alarms.
Main Motor Overload
Main-motor overload generates an alarm.
Infeed Drum Jam
An infeed-drum jam generates an alarm.
Outfeed Prism Jam
An outfeed-prism jam generates an alarm.
Outfeed Pusher Jam
An outfeed-pusher jam generates an alarm.
Tunnel-Conveyor Overload
Tunnel-conveyor overload stops the washing machine.

What bottle sizes and materials can the Linear Tunnel Type Bottle Washing Machine handle?
The machine is suitable for approved glass, PET, HDPE and PP bottle configurations from 50 mL to 1 L (1000 mL).
Which HMLBWM models and outputs are available?
The available configurations are HMLBWM-120 for 120 BPM, HMLBWM-150 for 150 BPM, HMLBWM-180 for 180 BPM and HMLBWM-240 for 240 BPM.
What does BPM mean?
BPM means bottles per minute and identifies the rated output model.
How are bottles fed into the machine?
A wire-woven infeed belt transfers approved bottle formats toward the infeed handling system.
How are bottles loaded into and unloaded from the pockets?
Mechanical cams load and unload the bottles, while HDPE pockets carry them through the washing positions.
How many internal washing positions are provided?
Five internal washing positions are provided in the defined air, RC-water and PW sequence.
What is the five-position internal wash sequence?
The internal sequence is compressed air, recirculated water, compressed air, fresh Purified Water and compressed air.
What is the external bottle washing sequence?
Two external washing stages are provided: recirculated water followed by compressed air.
How many tanks and pumps are supplied?
