Cleaning of glass bottles with ionized air

By Jordi Torres, Export & Marketing Manager at Traktech

One of the first steps in the glass bottle filling lines after depalletizing and placing them on the conveyor belt, either manually or through an automatic glass bottle depalletizer, is cleaning the inside of the bottles in order to remove any foreign body or dust that could have fallen inside and deliver the clean bottles for filling.

This interior cleaning of glass containers can be done in several ways depending on the type of industry.

“Lost water” system

A very popular way of cleaning bottling plants, especially those of wine, is through water. It is a system known as a “lost water” system, but this system is becoming obsolete due to the large consumption of water that is needed.

Many companies are already trying to reduce this high-water consumption due to the expense it represents, as well as the non-sustainability of the system. Apart from the problem of water consumption, water cleaning machines must have an air-drying system installed to ensure that the bottle is completely dry before filling.

It is interesting to note that in Spanish, empty container cleaners, whether made of glass, plastic or metal, are called “Enjuagadoras” that comes from the verb “enjuagar” that etymologically comes from the Latin word “exaquare” which means  “limpiar con agua or wash with water ”.

Different solutions for rinsing bottles without water

In order to provide solutions to the market, the rinsing machine manufacturers suggest different solutions to replace the cleaning of the inside glass bottles with water, such as neutral gas cleaning, like nitrogen and ionized air cleaning.

  • Bottle cleaning system with neutral gases

The cleaning system through neutral gases, such as nitrogen, has the advantage that the gas leaves no residue in the form of odours or flavours due to its neutral gas condition.

It is the same gas that is used for vacuum packaging, where once the oxygen is extracted from the container, nitrogen is injected to prevent the packaged product from being crushed or deformed by the action of the pressure change.

In both cases the gas consumption is very high which represents an important cost for the producer.

 

  • Cleaning of glass bottles with ionized air

Traktech proposes as solutions to the market our packaging cleaners models Rinser SG, Rinser R and Twistrinser with ionized air. These empty bottle cleaners by air, whether made of glass, plastic, PET or metal, can be equipped with three different cleaning systems:

 

1. Standard blowing.

2.- Blown with ionized air and aspirated particles with F8 filtration

3.- Blown and aspirated with the IonRinse® system.

Traktech collaborates with the company Meech International, the supplier of the Ionized air equipment that we install in our empty bottle cleaner, Rinser models.

Standard blowing and blowing installations with ionized compressed air and particules suction with F8 filtration use compressed air with a consumption of approximately 400/500 Nli / min, while the patented blow and aspiration set with the IoneRinse® system does not use compressed air with the consequent saving of energy and costs for the manufacturer.

For companies where a simple blow is enough to clean the inside of the empty bottle, the first solution is ideal since with minimal investment it achieves acceptable results.

Traktech recommends the ionized air cleaning system for glass or PET bottles with excellent results.

Depending on the productions requiremenys, we can recommend the ionized air and aspiration system that best suits the needs of the companies with low production, whether blowing with ionized compressed air and suction of particles filtered with F8, or blowing and aspirating with the patented IonRinse® system is recommended for higher productions.

This system is the one that is installed in our TwistRinser, the high-speed bottle inverter cleaner for PET / HDPE bottles installed on air conveyors in existing “beverage lines.”
