How does Aseptic Filling Process Work?

In today’s industry, you will find a variety of aseptic filling machines.

The packaging container will determine the working principle of an aseptic filling machine.

What will remain constant in the entire process is the sterilization stage.

When you purchase an aseptic filling machine, make sure the manufacturer fully trains your team.

This training will enable your team to operate the machine appropriately once installed.

You will use weight or volume to fill the containers.

A volumetric filling will use a magnetic flow meter, which ensures the accuracy of the flow of liquid.

These flow meters will control the membrane valves to begin and end the filling cycle.

You will fill the bottles without touching the bottle since the product is in liquid form.

If you have products that foam, you will control the flow rate during the filing process to avoid spillage.

You will fill by weight if the packaging container used to hold the liquid is in grams.

This process can be difficult when using high-speed operations.

It is because collisions and vibrations with the system may alter the measurements.

In short, the aseptic filling process involves:

i. Feeding the containers

ii. Feeding the liquid or product

iii. Switching on the machine

iv. With the help of conveyor belt the machine moves the containers

v. It fills the containers

vi. Seals the containers

vii. Inspects for quality control

viii. Prints necessary information

ix. Discharges fully filled containers

Remember, most modern machines have fully automated system.

It can be called in various names depending on the type of container used.

It can be called a bottle loading, ampoule loading, or vial loading station.

Conveyor Belts

This part of the aseptic filling machine will assist in transporting the containers from one point to the next.

Some machines have grippers installed that hold the containers in place during the filing process.

Aseptic Container Forming Station

An aseptic filling machine will use either a thermoforming or blow molding technique which forms the current aseptic container.

This station will mean that your aseptic filling machine will make and fill the containers at the same time.

Which Sterilization Technique do Aseptic Filling Machines use?

Applying different sterilization techniques will enable you to destroy all forms of microorganisms from a substance.

Some of the sterilization techniques that a Sterilization Technique use include:

Chemical Sterilization

Here you will sterilize by using gases.

The gas quickly penetrates the product meaning the sterilization is effective.

The gases that you will use for sterilization are will kill all germs and bacteria.

Ethylene dioxide and carbo-dioxide are the gases that you will apply in this process.

You will add carbon-dioxide to minimize the chances of an explosion.

Heat Methods

This method is a commonly used type of sterilization.

Using heat will kill the microbes contained in the substance.

In this technique, if you expose the substance for long to heat, the better it is sterilized.

If you use a high temperature means you will expose the substance to heat for a shorter time.

You can use two types of heat sterilization technique:

  1. Dry heat method
  2. Moist heat method

Filtration Methods

In this sterilization process, you will pass fluids through bacterial filters to remove the microbes in them.

You will use this method to sterilize heat-sensitive liquids.

This method has the disadvantage of clogging and that you have to apply it for a long.

You can use three types of filters in the filtration sterilization process.

  1. Seitz filters
  2. Membrane filters
  3. Candle filters
