Innovative cathodic protection
Durable corrosion protection for Ecocreation Ecodigesters
Ecocreation offers controlled electro-chemical protection in its Ecodigesters for customers working with a high-acid organic waste stream. This module is available on the Ecocreation All-in-One range and on the Ecocreation Industrial Range.
This protection on Ecocreation Ecodigesters is an electrochemical technique used by Ecocreation to protect the stainless steel (SS) Ecodigesters from corrosion, especially in high-acid environments. This process prevents metal oxidation by keeping the metal in a protective state to prevent corrosion.
This solution ensures that the metal in contact with highly acidic organic (food) waste remains negatively charged. This stops the natural rusting process. This significantly extends the life of the machines, even in highly corrosive conditions.
Application in fruit and vegetable processing
During fruit and vegetable processing, processing machines often come into contact with organic waste streams with high acidity. This acidic environment normally accelerates the corrosion process, even in stainless steel, which can lead to structural damage, loss of performance and higher maintenance costs.
Ecocreation has innovatively applied electrochemical protection to its Ecodigesters. This technique, combined with specially selected metal alloys, enables the machines to process organic streams with high acidity without corrosion problems. This makes the machines not only more durable, but also extremely reliable, even under intense loads.
Benefits of this innovative application:
Through this progressive approach, Ecocreation is setting a new standard in the industry, offering customers not only cost advantages, but also a more sustainable and hygienic solution for processing organic waste streams.
Cathodic protection with a controlled electric current offers a significant advantage over protection with sacrificial anodes, which operate through an uncontrolled chemical process. The main advantage is that with cathodic protection, the current intensity and protection levels can be precisely controlled and adjusted to the conditions. This results in more efficient and sustainable protection of the steel, whereas sacrificial anodes become consumed over time and need to be replaced periodically. As a result, cathodic protection offers a more reliable and maintenance-friendly solution, especially in environments with high corrosive loads.
Operation of cathodic protection
In cathodic protection, the steel to be protected is connected to a sacrificial anode or an external electric current source. This anode or current causes the steel to become negatively charged, stopping its natural tendency to rust. The corrosion process is reversed or slowed down, as it were, because the steel itself no longer loses electrons and therefore does not oxidise.
Application in steel machinery for processing fruit and vegetables
In fruit and vegetable processing, machines often come into contact with materials with low pH, meaning they have high acidity. These acidic conditions significantly accelerate the corrosion process, as acid can accelerate the oxidation process of steel.
Ecocreation applies cathodic protection in its stainless steel Ecodigesters used for processing organic waste streams with high acidity, such as fruit and vegetable residues. This keeps the machines in good condition for longer, even in these challenging working environments.
Benefits of cathodic protection in this application:
Ecocreation's application of cathodic protection is an innovative example of it applying technology that can contribute to more sustainable and efficient processing of organic waste streams and food waste.
