Description

Fruit ripening system

technical field

The present invention relates to a fruit ripening system, in particular to a gas chamber and a ripening chamber, which can be used for ripening and ripening of various fruits such as bananas, mangoes, papayas or avocados.

Background technique

Generally, the traditional ripening room is long and narrow and has multiple passages inside. Due to the long and narrow structure, the ripening room needs to be equipped with a large cooler, a gas air conditioner and a foldable airtight door. And this ripening room is generally provided with 6 passages at least, and each passage is only a small volume, can only accommodate a small amount of fruit of 20 to 24 pallets at most, needs 6 days to carry out ripening cycle and ripening process, just can A daily output of 20 tons is achieved. And when transporting pallets into the ripening room, the airtight door needs to be opened first, and then the ripening process of bananas is carried out. The ethylene gas used in the ripening room needs to be discarded after 24 hours of use, and the ripening of bananas cannot be quantitatively measured. Spend. Furthermore, in the ripening stage, due to the airtight chamber and the airtight door, the ripening chamber has a high concentration of carbon dioxide, which will slow down or stop the ripening process due to excessive carbon dioxide concentration, and even cause the fruit to produce peculiar smell. Therefore, the traditional ripening room for bananas must also reduce the concentration of carbon dioxide through a large-scale and periodically functioning ventilation system, resulting in very expensive setup costs for the traditional ripening room.

In addition, the traditional ripening room adopts the method of cooling and heating at the same time during the ripening process of bananas. During the ripening stage, the bananas are first placed in the ripening room and heated for more than 48 hours to raise the temperature to at least 18 degrees, since more than 48 hours of heating time is required, this will also heat the floor and aisle in the aging room, and the temperature of the entire aging room including the floor and aisle must be cooled to 14 degrees during the aging process. Each aging cycle needs to use the same method. First, heat the floor and aisle in the aging room to at least 18 degrees and then cool it down to 14 degrees. It takes a lot of energy to continuously heat up and cool down the aging room. .
