Food Cleanroom Considerations

Food processing cleanrooms differ from traditional cleanrooms. Especially for food production, requirements for internal facilities and personnel are extremely high. In this regard, GMP food cleanrooms are clearly distinguished from traditional cleanrooms: traditional cleanrooms may mainly focus on indoor cleanliness, while food industry cleanrooms must consider microbial, chemical, and other contaminants that cannot be detected by simple particle counting.

Food products include various forms such as tablets, capsules, oral liquids, powders, granules, etc., each requiring specific environmental controls. Product quality compliance means not only that the product meets registered quality standards, but also that the entire process complies with Good Manufacturing Practice (GMP) and HACCP principles.

Energy saving is a priority in Berbson's cleanroom system solutions. We excel at providing environmental solutions that meet international standards (GMP, ISO 14644, etc.) while applying the latest energy‑efficient technologies.
