Grape Cold Storage Warehouse

Haocool designs these cold storage warehouses for grapes and other fresh fruit storage

• The freezing point of grapes is around -3℃, which means the storage temperature needs to be in a range of -1～0℃. If the environmental temperature is less than the freezing point of grape, the fruit will become damaged due to freezing.
• The best humidity for grapes is an environment with about 90-95% humidity. When humidity is outside of this range, the grape will rot and the stem will dehydrate. Therefore, keeping a suitable environment for the grapes is an important component for grape storage.
• Decreasing the oxygen content or increasing the carbon dioxide content in the environment is helpful to long term storage of grape. Generally speaking, the suitable oxygen content is 2～4%, and the suitable carbon dioxide content is 3～5%.
• Late maturing grapes can be stored for about 2-7 months in a cold storage facility.
• If the client wants to prevent rotting, a fungus free environment must be guaranteed, as fungi types common to grapes have a low temperature resistance.

Project profile

Grape cold storage warehouse information

In order to monitor the produce condition, Haocool has installed an inspection window on the cold storage warehouse. This window has passed air tightness tests, with a pressure tightness of 300MPa and a half-depressurization period of 20-30 minutes.
