This document discusses various types of kitchen equipment including refrigerators, freezers, auxiliary equipment like griddles and broilers, microwave ovens, and blenders. Refrigerators and freezers are necessary to prevent bacterial growth in foods by maintaining proper storage temperatures. Auxiliary equipment has both specialized and optional uses in large food establishments. Microwave ovens have increased in use for food preparation as foods can be prepared ahead of time and reheated. Blenders are used to chop, blend, mix, whip, puree, grate or liquefy different foods.
