Refrigeration In ancient times... The use of ice to refrigerate and - PowerPoint PPT Presentation

Refrigeration In ancient times... The use of ice to refrigerate and thus preserve food goes back to prehistoric times. Through the ages, the seasonal harvesting of snow and ice was a regular practice of most of the ancient cultures: Chinese, Greeks, Romans, Persians. Ice and snow were stored in caves or dugouts lined with straw or other insulating materials. This practice worked well through the centuries, with icehouses remaining in use into the 20th century. Today... Cooling systems have progressed through the ages and now, Vitrum Group, presents their modern, e ffi cient and reliable Central Cooling System. This presentation will introduce the new cooling system including its new features and capabilities. We hope you enjoy!
