The Optimized Grind Finishing® process (OGF)
In the pharmaceutical, chemical and food processing industries, minimizing build-up in containers is a critical factor for efficiency and quality. The build-up of substances on the inside walls of containers can lead to increased cleaning effort, product losses and contamination. This costs money and ties up resources. Especially in industries where EHEDG (European Hygienic Engineering & Design Group) certification and hygienic design are becoming increasingly important, minimizing adhesion has become a critical factor.
Research carried out by BOLZ INTEC in cooperation with the University of Constance has shown that the way in which stainless steel surfaces are removed plays a key role in minimizing adhesion. Different grinding methods result in different adhesion behavior, despite the same Ra values, and the OGF process from BOLZ INTEC leads to a lower adhesion of particles.
Easy cleaning & minimal adhesion
The Optimized Grind Finishing® (OGF) process leads to a low adhesion of particles on the surfaces of the containers. This significantly improves cleaning efficiency and reduces the risk of contamination of product batches.
Reproducible surface quality
The OGF process enables reproducible surface quality. In contrast to conventional processes, in which variable factors such as manual contact pressure or the quality of abrasives play a role, the OGF process offers consistent surface quality.
Visual aesthetics and low number of errors
The stainless steel surfaces treated with the OGF process have an attractive appearance and defects in the surface structure are significantly reduced thanks to the fine and gentle removal process. This is particularly important in industries that place high demands on safety.
Improved corrosion protection
The electropolishing process not only improves the optical quality, but also results in chemical changes that lead to improved corrosion protection. This is particularly relevant for applications in chemical and pharmaceutical processes.
Reduced risk of batch contamination
The improvement in cleaning behavior through the OGF process leads to a significant reduction in residual dirt adhesion in the containers. This significantly reduces the risk of contamination between different product batches.
Applicability in critical industries
The process is seen as particularly advantageous for critical industries such as nanotechnology or biotechnology and pharmaceutical technology, where the highest purity requirements and the avoidance of contamination are of crucial importance.

Hygienic design plays a crucial role in stainless steel drums for the pharmaceutical industry, as it ensures that the drums meet the high hygiene standards required in this sector.
Here are the main aspects that make up hygienic design for stainless steel drums in the pharmaceutical industry:
Minimization of contamination: Hygienic design aims to minimize the adhesion of particles and facilitate cleaning to avoid contamination. This is particularly important to ensure the purity of pharmaceutical products and prevent the carry-over of particles.
Smooth surfaces: Stainless steel drums are manufactured with smooth, gap-free surfaces that allow residue-free emptying. This is crucial to ensure that no product residue remains in the drums that could lead to contamination.
Material selection and surface treatment: The drums are made of high-quality stainless steels that are corrosion-resistant and suitable for handling aggressive chemicals. Processes such as electropolishing and special grinding and polishing methods are used to improve the surface quality and optimize the cleaning properties.
Design measures: The design avoids dead spaces and undercuts where product residues could get stuck. This is achieved through the use of smooth, seamless constructions that enable easy and thorough cleaning.

Stainless steel drums for pasty and liquid media differ in several aspects that are tailored to the specific requirements of the respective media:
Emptying systems:
Special emptying systems are required for pasty media, which enable almost residue-free emptying. These systems often use compressed air or mechanical ejection plungers to gently push the medium out of the drum.
Liquid media can usually be emptied more easily by gravity or pumps, whereby standard systems are sufficient for emptying.
Seals and closures:
Pasty media often require special seals and closures to ensure that the medium does not escape and that no air bubbles form that could hinder emptying. With liquid media, the requirements for tightness are also high, but the systems are often less complex as liquids flow more easily.
Material and construction:
The stainless steel drum is made of high-quality stainless steel, which is corrosion-resistant. However, drums for pasty media can have additional reinforcements or special internal coatings to prevent the medium from sticking.
The design can also have differences in surface treatment to optimize cleaning and handling of the respective media.
Areas of application:
Pasty media are often stored in the food, cosmetics and pharmaceutical industries, where gentle handling and precise dosing are important. Liquid media are also used in these industries, as well as in the chemical industry, where the storage and transportation of liquids such as chemicals or oils is paramount.
