The use of grills or perforated boxes in defrost processes avoids direct contact between exudate and food, reducing the risk of bacterial proliferation and maintaining food organoleptic characteristics. The new drain box kit is engineered to defrost faster. It allows liquid that comes out of food (meet and fish especially) to the bottom through the holes, avoiding its accumulation on the contact zone. For a faster defrost process, removing original packaging is recommended. Food will be placed inside the perforated box. Then this box will be fitted into the other box avoiding dripping and cross-contamination of other food nearby. Food should be covered with a lid to protect it and avoid potential contaminations.
