This question already has an answer here:
I've a factory of 300 people and I serve them lunch everyday. At the moment the kitchen is adjust-en with the factory but I have to move the kitchen asap to a place around 20kls. far from my factory. The big problem is I'm not sure how to deliver them from my kitchen to factory. I like to box every meal separately. At summer the temperature is 40+ C outside and my concern is will the food be safe to travel from kitchen to factory without getting spoil. Do I need refrigerated vans and if then how will I be able to warm them up ? I will be using stainless steel contains to carry the foods. Please advice.
