Packing house
（重定向自Packinghouse）
A packing house is a facility where fruit is received and processed prior to distribution to market.
Bulk fruit (such as apples, oranges, pears, and the like) is delivered to the plant via trucks or wagons, where it is dumped into receiving bins and sorted for quality and size. In the case of citrus, ripe fruit with a greenish tint is placed in special storage rooms where ethylene gas is used to bring out the color. Obvious "culls" (fruit that is not suitable to sell for eating due to cosmetic defects) is removed and sold for juice or other uses. Fruit that is ready to be packed into crates or flats is run through a washer and then air-dried. A light coating of natural wax is applied to help the fruit retain moisture and enhance its appeal.
