    1.What is an ampoule filling line?

    ampoule filling line

    An ampoule filling line is a versatile solution for filling fluid products under sterile conditions.
    It is an integrated state-of-art technology for the mass production,but can also be offered as a piece of stand-alone or single machine.

    Ampoule filling is a sensitive process,it is a linkage line that cosists of vertical ultrasonic washing machines, hot air circulation sterilization tunnel, ampoule filling and sealing machine.

    It can carry out water flushing (internal and external), preheating, sterilization, cooling, filling, sealing, and other tasks.And it is well-flexible to fill and seal ampoules of various capacities like 1ml, 2ml, 20ml, 25ml, etc.

    2.How ampoule filling line originated?

    ampoule filling line originated

    Traditionally, in some cultures, ampoules were meant to contain a martyr’s blood after death that entombed alongside the person’s burial sites.

    In the 1800s, chloroform was frequently used anesthesia for healthcare purposes. Hence evolution of ampoules began by utilizing them as a storing medium.

    By the time, hermetically sealed glass ampoule was introduced by a French Pharmacist Stanislaus Limousin in the 1890s. These were meant for sterile pharmaceutical preparations. Besides this, oxygen bottles, and balloon equipment for therapeutic oxygen are also invented by Limousin.

    Medicines and technologies have developed over time. The utilization of ampoule also changed although storing a small number of gas or liquid has pretty much remained the same.

    4.What is the working principle of the ampoule filling line?

    Ampoule filling lines are constructed on the principle of slant transport.
    The machine has an integral working principle that can be categorized into the following sections.

    ampoule filling line-1

    Cleaning Zone- Ultrasonic Washing

    Cleaning Zone- Ultrasonic Washing

    Washing Tunnel

    Washing Tunnel

    An unpacked set of ampoules are introduced for cleaning where inverted ampoules are exposed to ultrasonic washing using circulating water for injection. This process is taken place twice. After circulating water flushing compressed air is introduced for good cleaning effects that induce excellent protection against contamination. Compressed air is facilitated inner and outer surfaces of the ampoule.

    Sterilization and Drying

    This process is divided into three sections

    Sterilization and Drying

    Pre-Heating Zone

    Pre-Heating Zone

    De-pyrogenation Zone

    Here, pre-heating is a mandatory step before coming procedures. The ampoules are entered gradually through the mesh belt. They are exposed to hot air via laminar flow for short time under a high temperature. Whereby the exposure to heat above 250°C destroys the pyrogens. This step is of prime importance for ampoules bottles, and medicinal ampoules to ensure pyrogen-free outcomes.

    High-Temperature Zone

    Drying and Sterilization Tunnel

    Drying and Sterilization Tunnel

    The machine is equipped with a front-back laminar flow box and high-temperature sterilization box. Such boxes are supplied with medium and high effect filters blowing 100-grade purified air. This ensures the entered ampules are protected. High temperatures zone destroying microbial growth supplying temperature up to ≥350⁰C); with time ≥5 min. The entire process is operated following real-time monitoring.

    Cooling Zone

    Cooling Zone
    When ampoules are de-pyrogenated completely. They are encountered to cooling zone to be cold. The sterilization process is set on the ‘operator terminal’ and programmed to ensure correct sterilization which makes it difficult for the flow of hot air to reach ultimately normally ‘Colder’. The cooling zone cools out the sterilized ampoules to fulfil technological needs.

    Ampoule filling and sealing Zone

    Ampoule filling and sealing Zone

    Ampoule Filling and Sealing

    The filling and sealing zone are accompanied by 100-grade pure air. This section is equipped with dispensing pumps as well as laminar airflow to prevent the product against contaminated during filling. On one hand, the filling product is dispensing while on the other hand, sealing the tip of the ampoule is taking place. The treated ampoules are finally discharged.
