Ordering food is a common freezer equipment in hotels and restaurants. Ordering is generally divided into refrigerated display area and frozen display area. The refrigerated display area and the frozen display area are generally separated by partitions, which are made of foamed materials and have good thermal insulation performance. Generally, the temperature in the refrigerated exhibition area is controlled at 0 ~ 10℃, and the temperature in the refrigerated exhibition area is controlled at -5 ~ 0℃ to meet the storage requirements of different dishes.
