Now is the time for lychee to be mass-marketed. This year due to climate and natural disasters, the national lychee production has become a foregone conclusion, the impact of early maturing varieties is slightly less, and the production of middle and late maturing varieties is expected to be only one to two percent of last year. According to the statistics of the National Litchi Longan Industrial Technology Research and Development Center, the total output of litchi in the country this year is 1.78 million tons, which is 45.94% less than last year.
Litchi is one of the most difficult fruits to store and transport. The freshness and flavor of litchi will decrease rapidly after picking due to the characteristics of high respiratory intensity and easy skin water loss and Browning. Therefore, there are three elements of litchi preservation: temperature, humidity and speed. According to the characteristics of litchi storage difficulties, Fstsort has designed a set of litchi cleaning, pre-cooling and packaging lines. After litchi harvesting, due to its own residual heat, if the pre-cooling link is reduced, it will inevitably lead to the deterioration of lychee transportation.
This set of lychee processing equipment from cleaning to packaging can be quickly pre-cooled and anti-corrosion and color protection treatment, and then loaded into the foam box with ice storage and transportation, which is currently the common application of litchi in the south of China. The lychee processing machine has been put into use in a packaging plant in Hainan, and practice has proved that the equipment not only reduces the manual demand, but also greatly improves the efficiency of litchi processing. In order to realize the commercialization of litchi after harvest, some packaging factories also purchased litchi sorting machines, so that the quality of litchi in each box is consistent. Although the price of litchi after commercialization is high, the key for consumers to buy lychee is quality, and fresh and good quality litchi is more popular.
