From goods in, which takes place 7 days a week, food follows a path through dry stores holding to coldroom storage (see Figure 7.4). Food then follows a horse-shoe shaped flow to preparation, hot kitchens, blast chilling, tray assembly, and dispatch chiller. Great attention has been paid to prevent back-tracking and cross-contamination from areas; for example, the hot kitchen preparation area has one door in from the food storage area and a second door out to hot kitchen.
