The cold storage and grain depot on the ship are located near the kitchen, requiring the entrance and exit far away from the bathroom and convenient handling.

According to the different requirements for the cold temperature of the food, the large and medium sea ships usually have 3~4 storeroom (vegetable storehouse, fish stock, dry stock), which store meat, fish, vegetables, fruit and milk, eggs and so on. The grain depot is used for storing rice flour, cooking oil, wine and beverages.
