The image shows a stainless steel milk plunger, also known as a “meneador” in Spanish, which is used for stirring milk. It consists of a circular perforated disc at one end, attached to a long, slender rod with a triangular handle at the other end. Milk plungers are commonly used in the dairy industry and in homes for mixing milk, cream, or other liquids. Stainless steel is a preferred material for these tools due to its durability, resistance to corrosion, and ease of cleaning. The smooth, non-porous surface of stainless steel helps prevent bacterial contamination, ensuring the safety and quality of the milk.
