Best Technology of Ampoule/Vial Washing Machine in 2023

The Ampoule/Vial Washing Machine is the equipment used to clean the primary packaging material like Ampoules or vials in Injectable or vaccine manufacturing plants. In this blog, we briefly provide a description of the working principles, uses, procedures, processes, and validation. Operation of this washing machine is like that, Ampoules/vials shall be loaded manually to the in-feed bay by SS trays and transferred to the washing machine in a group by the transport system. The Ampoule/Vial Washing Machine has a washing unit that shall wash the ampoule or Vial from the inside as well as from the outside.

The washing cycle shall include washing with filtered re-circulated WFI, Internal blow with compressed air then washing with purified water followed by a second blow of compressed air, and be finally washed with WFI and drying with 0.2 microns filtered compressed air.

Ampoule washing machine shall be provided with a minimum of six washing stations. The washed Vials/Ampoules shall be transferred to the tunnel by the conveying system under LAF.

Types of Ampoule/Vial Washing Machine :

1. Rotary washing machines: Rotary washing machines have varied outputs of vials and work in rotary motion.

2. Linear washing machine: Linear washing machine’s work is to automatically load arrangement facilities of vials onto SS wire mesh conveyor through a feed conveyor and vials are fed into pockets directly.


Working Principle of Ampoule/Vial Washing Machine :

The Ampoule/Vial Washing Machine works on the principle of jet washing the individual vials or ampoules in an inverted position by a series of jets.

The vials are loaded on the loading station by placing a box or tray of vials on it. The complete layer of the vials is pushed to the in-feed conveyor then the vials go to the machine’s platform.

Where an in-feed lifter carries the vials into the pockets. After vials reach into pockets, the pocket channel runs to the backside.

During this process, the pocket channel stays, the washing nozzle manifold raises up and a nozzle enters into the mouth of each individual vial.

A solenoid valve of the water and air lines is activated and a jet of air/water hits the inside and outside of the vial to thoroughly clean it.

Washing will occur in the following sequence in the Ampoule/Vial Washing Machine.

Number of Wash Cleaning Agent
1st  Wash Compressed Air – Internal Wash
2nd Wash Re-circulated Water – Internal + External Wash
3rd Wash Re-circulated Water – Internal Wash
4th Wash Compressed Air – Internal Wash
5th Wash Purified Water – Internal + External Wash
6th Wash Purified Water – Internal Wash
7th Wash WFI Water – Internal Wash
8th Wash Compressed Air-Internal + WFI External-Wash
9th Wash Compressed Air – Internal + External Wash

Ampoule/Vial Washing Machine

Major Components of the Ampoule/Vial Washing Machine :

  1. The Vial/Ampoule entry Conveyer: this is made of two sections of net belt structure to ensure that the Bottle/Vial/Ampoule has enough thrust. So that the lead screw does not lack the Bottle/Vial/Ampoule and does not pour the bottle, so to ensure the stability of the bottle. (Net belt specific width).
  2. Lift device: This is made up of a wheel and camshaft. The sliding block is embedded in T type of slot around the wheel. The support plate is set on the sliding block. Also, Pulley is set on the camshaft of the sliding board. Pulley turns the sliding board moves up and down. It makes the bottles Bottle/Vial/Ampoule transport accurately.
  3. Oil leakage prevention mechanism: This is arranged on the extending rod of the mechanical hand and the large market to ensure that the lubricating oil does not pollute the sink.
  4. The utility model is provided with a needle anti-shake device, which improves the accuracy of the injection needle entering the bottle and reduces the broken bottle and the broken needle phenomenon in the high-speed operation of the bottle.
  5. The clamps and its mechanical arm: This will use non-toxic pollution-free polyamine material. It has both a damping effect and good strength, to protect the bottle from breakage, and enhance the serving life as well.
  6. The inner surface of the cleaning process has been completed a total of three times for flushing and the outer wall of a bottle of water and gas washing. A spray needle is fixed corresponding to a cleaning medium without cross-contamination; the spray needle is inserted into the bottle for tracking and cleaning; the bottle mouth cone positioning guiding device is adopted to reduce the damage to the bottle by spraying, and the cleaning effect is good Ampoule/Vial Washing Machine.
  7. Filters and their Assembly:
    • Recycled water, 3um polyethersulfone filters,
    • Water for injection, 0.22um polyethersulfone filter,
    • Compressed air, 0.22um PTFE filter.

The washer will apply one-time WFI washing and two times recycled water washing. It uses the needle to track and insert, and the PLC controls the solenoid valve to intermittently spray water and jet to achieve effective cleaning under the energy-saving state.

At the same time, the WFI water after cleaning will be used as circulating/recycled water after passing through the return water tank, the sanitary water pump, and then filtering through the filters.

FAQ regarding Ampoule/Vial Washing Machine:

What is ampoule washing machine?

Answer: The machine known as an ampoule washer is made specifically to wash ampoules with the least amount of touch to any machine components. These machines are equipped with a Gripper system that is specially intended to hold and support the ampoules from their necks while inverting them throughout the washing process and even release them once the washing is over. Following washing, they are discharged via a feed worm system, which is an outfeed system. These feed worm systems are kept upright to guarantee the successful washing of ampoules.

How ampoules are washed?

Answer: The most effective approach to cleaning an ampoule is to use a high-pressure jet spray both inside and outside the bottle. If you use WFI water to spray the washing, it will work better. When cleaning duties are completed, minute bacteria, contamination-causing particles, contaminated substances, and bacterial toxin residue are all eliminated.

What is vial washing machine?

Answer: vial washing equipment designed to clean the internal and external surfaces of vials. Vials are kept in pockets while being cleaned. It features 2 to 16 washing stations, each with 3 to 5 internal water washes using recycled water, purified water, and WFI, as well as three to five air washes. One water and air wash are used to clean the exterior surfaces.

How many cycles are there in vial washing machine?

Answer: Followings are the washing cycles for vial washing:

1st  Wash            Compressed Air – Internal Wash

2nd Wash            Re-circulated Water – Internal + External Wash

3rd Wash             Re-circulated Water – Internal Wash
