What must be matched when converting a machine to food grade lubrication?

When converting a machine to food grade lubrication, it is crucial to match the specifications of the previous lubrication. This ensures that the new lubricant is compatible with the machine's design and operational requirements. Food grade lubricants must meet certain regulatory standards, and substituting them without considering previous specifications could lead to ineffective lubrication, which may compromise the performance and safety of the machine.

Matching the specifications helps avoid potential issues such as incompatibility with seals and gaskets, which can lead to leaks or contamination of the food products being processed. Additionally, maintaining the same viscosity and performance characteristics as the previous lubricant is essential for the machine to operate correctly.

Other factors like the size of machine parts, voltage of electrical components, or color coding do not directly relate to the functionality or safety of the lubrication system in a food processing setting.
