Successfully make high pressure dragon fruit washing machine
The Sub-institute of Agricultural Electrical and Postharvest Technology has successfully researched and manufactured high pressure dragon fruit washing machine, with a rotating nozzle system that combines static spraying, increasing efficiency of cleaning and minimizing damage fruits.

According to engineer Nguyen Duy Duc, a member of the research team, initially, the washing machine research team was not fully automated, in order to maintain jobs for workers, especially women in packing houses. The machine is installed for Hoang Phat Company, with a high rate of cleaning because of single washing of each fruit.

However, enterprises want to have a system with higher productivity, reduce the number of people operating the machine, so the group continues to research for the second generation machine helped Hoang Phat Company (Long An) export thousand tons of high quality dragon fruits to some countries like Japan, Korea, Canada, China, and etc.

After a period of operation, the group found it necessary to change the type of nozzle so that it could be easily removed for cleaning, maintenance, and cleaning. At the same time, it is necessary to improve the quality of the nozzle, ensure that the water rays do not cancel each other out to increase the efficiency of cleaning, reduce damage fruits during the transition between the machine and packing conveyors.

Mr. Nguyen Hoang Huy, Director of Hoang Huy Limited Company (Chau Thanh, Long An), said that the dragon fruit washing line was installed at the company since the beginning of 2019. Over time of use, the fruit cleaning effect is very high and minimizes the damage to the fruits.

White flesh dragon fruit cleanliness reaches 98 - 99%, red intestine reaches 96 - 97%; damage rate below 4%. In addition, the machine also helps the Company reduce labor costs and increase the efficiency of handling fungicides for fruits after harvest. Thence, the company has expanded its business to export dragon fruits to many countries, such as Australia, Japan, America, Korea, EU, and etc.
