Blueberries are a superior fruit on the Chinese market. Every year during the first half of July, 70% of the whole blueberry production volume goes on sale. The sales period is collective for blueberries. The storage and preservation of the blueberries is troublesome and there is a coincident rain season on the market. All of this combined makes a lot of farmers worry that the blueberries will go to waste before harvest, ruining the invested capital. So they dump the blueberries at low price. In general when the blueberries go on sale, 500g is sold for around 20 RMB. But after August, the blueberry season is over and 500g can reach a price of 100 RMB.
Drawing from the technology for cold storage from the US and Japan, the Dalian Lanmeigu Manor and Bingshan group started to develop a series of pre-cooling and cold storage systems. After pre-cooling, the original 30% loss is reduced to 5%. The taste and firmness of the blueberries are preserved and they can be preserved for 4 days even at room temperature. As such, the shelf life of the blueberries is prolonged and they can be transported further away. Moreover, Lanmeigu Manor also promotes two sets of storage systems.
