pölytys

Pölytys is a Finnish term denoting the act of applying a fine powder to a surface. Derived from pöly, meaning dust, the word is used in various Finnish technical, industrial, and culinary contexts to describe the distribution of powdery particles in a controlled manner. The precise meaning depends on the field, but it generally refers to spreading or depositing powder evenly over or into a target.

In manufacturing and materials processing, pölytys often refers to processes such as powder coating, where a dry powder is electrostatically charged and sprayed onto a substrate and subsequently heated to form a solid coating. It can also describe applying dry lubricant powders to moving parts to reduce friction, or using powder substances as release agents in molds. Equipment used ranges from hand dusters and brushes to automated spray or pneumatic deposition systems.

In food preparation, pölytys commonly means dusting a surface or product with powdered ingredients such as sugar, cocoa, flour, or starch to decorate, flavour, or prevent sticking. In bakery and pastry work, a final dusting is a common finishing step.

In pharmaceutical and cosmetic contexts, pölytys can describe the preparation and handling of fine-powder formulations, including the distribution of powders in tablet making or topical products, where uniformity and particle size are important quality attributes.

Safety and regulation: handling fine powders requires appropriate ventilation, dust controls, and personal protective equipment to minimize inhalation risks and potential fire or explosion hazards. Adherence to applicable occupational safety standards and proper storage and handling procedures are essential.
