"Post-00s" college students invented fruit and vegetable "living tanks" to degrade pesticides

Wu Jieyang and the living container he invented
.
The pulsed light energy in the incubator provides the necessary conditions for photosynthesis of fruits and vegetables
.
After five years of research and development, Wu Jieyang, a "post-00" maker who studied in Guangzhou, and his team members invented a "live tank" that can "resurrect" fruits and vegetables and degrade pesticides
.
Yesterday the reporter was informed that this “black technology”, which won the special prize of the Guangdong Maker Competition, has completed the transformation from design drawings to production applications, and is about to enter the formal production stage
.
Six iterations of research and development in five years, "living tanks" will be put into production as early as April 2018, Guangzhou Daily once said "Can refrigerators "resurrect" fruits and vegetables to degrade pesticides? "As the title, it reports the "multifunctional refrigerator" invented by Wu Jieyang and the maker team, who was still a middle school student at the time
.
Three years later, when the reporter met Wu Jieyang again, he was already a freshman studying in Guangdong Vocational and Technical College of Mechatronics
.
Wu Jieyang in front of him is no longer the shy little boy who used to be.
He is a little more calm and capable in conversation, and he is even more eloquent when he introduces his invention
.
Wu Jieyang slowly opened the door of the "living tank", and saw a variety of colored lights flashing alternately in the refrigerator, and white spray permeated it
.
In the refrigerator, all kinds of vegetables and fruits are placed in an orderly manner, absorbing the nutrients "cloned" from nature
.
"This is already the sixth generation product
.
" Wu Jieyang pointed to the "living tank" in front of him and introduced that the first generation product was just a titanium alloy plant growth tank.
The humidifier had to be artificially filled with water, after 5 years of continuous testing.
And after improvement, today’s “living tank” is more intelligent, can automatically add water, and the humidifier is moved from the refrigerator to the top of the refrigerator, and the improved light-emitting panel is also more suitable for the special environment of high humidity and low temperature in the refrigerator, thus Extend the service life of the humidifier and the light-emitting board
.
Why is this refrigerator named "Live Feeding Box"? Wu Jieyang explained that the traditional method of keeping fresh is to let fruits and vegetables "slowly die", but this refrigerator allows fruits and vegetables to "live slowly"
.
"Through countless experiments, we have obtained the most suitable light, humidity and temperature for the growth of fruits and vegetables.
Using a special device to emit the pulsed light required for plant growth is equivalent to'carrying the nutrients of nature' into the refrigerator.

.
"For example, Wu Jieyang said, for example, what plants need most is red and blue light.
At the beginning, he tried incandescent and neon lights.
It was not suitable until he found that LED lights could provide red and blue light.
This solved the key problem
.
How about refrigerators? Realize the effect of "degrading pesticide residues"? Wu Jieyang said that this "living tank" uses three methods of "photolysis", "hydrolysis degradation" and "in vivo metabolism"
.
Fruits and vegetables are left in the metabolism process.
In the artificial environment of the "living tank", the pesticide molecules undergo photolysis and hydrolysis reactions, and decompose into simple organic and inorganic substances, thereby losing toxicity and degrading pesticide residues
.
In order to eliminate reporters’ doubts, Wu Jieyang took out A test report
.
It turned out that in order to make this refrigerator more convincing, they also sent the prototype to the "Vegetables and Fruits Quality Supervision, Inspection and Testing Center of the Ministry of Agriculture and Rural Affairs (Guangzhou)" and the "China Guangzhou Analysis and Testing Center" for system testing.
, Fruit and vegetable preservation and pesticide degradation have obvious effects.
For example, when water spinach is sprayed with dichlorvos 15 times more than the national standard, the degradation rate will reach more than 70% within 24 hours, and the pesticide removal rate will reach 98.
1% after 48 hours
.
Talking about future plans, Wu Jie Yang said that he is currently preparing to produce 100 "living box" sample machines within two months, and then put them on the market one after another
.
He wants to let thousands of households enjoy the food, besides being a Maker University student, now Wu Jieyang also has a cool identity: In order to make the "living tank" be introduced to the market as soon as possible, he just registered Guangdong Shiyangjian Technology Co.
, Ltd.
in Guangzhou not long ago
.
"The company is named Shiyangjian.
, Is to embody the concept of sunny life and healthy world
.
"Wu Jieyang said
.
Wu Jieyang’s father, Wu Jian, recalled that one year during the Spring Festival, others were at home to celebrate the New Year.
Wu Jieyang was busy with experiments.
Unexpectedly, the experiment box caught fire at night and burned into a pile of scrap iron
.
Wu Jian encouraged him with the spirit of the Long March Son, tell him to succeed in one thing, he must overcome all kinds of difficulties
.

.
Up to now, Wu Jieyang’s maker team has obtained “a plant growth lamp”, “a method for degradation of pesticides based on LED pulsed light”, “a fresh-keeping device for vegetables and fruits based on LED pulsed light” and “a multifunctional refrigerator”.
One invention patent is authorized, and ten utility model patents are authorized
.
In addition, 14 invention patents are under public examination, and 16 PCT international patents are under public examination.
"A plant growth lamp" has also been granted a Japanese utility model patent, and the European Union and the United States are also under public examination
.
Not only that, in 2017, the Wu Jieyang maker team applied for the "2017 Applied Technology R&D and Major Technology Achievement Transformation Special Fund (Applied Technology R&D Support)" through a technology company in Shenzhen and Guangdong University of Technology, and obtained the Guangdong Provincial Finance Special support funds of 3 million yuan; In December 2017, Wu Jieyang and Wu Jie sent on behalf of Puning No.
2 Middle School to participate in the "2017 East Guangdong Youth Maker Competition" and won the special prize; in March 2018, they won the "Guangdong Province Primary and Secondary School Students" (Including secondary vocational schools) Maker Competition" special prize, and won the first prize of "Chaoshan Galaxy Award" for science and technology in 2018
.
Wu Jieyang, who has gained a lot, is still humble and low-key
.
During the interview, he mentioned many times that the invention of the "living tank" was not the result of him alone, but the crystallization of the wisdom of the team
.
In his view, the original intention of designing the "living tank" is to allow thousands of households to eat fresh and delicious agricultural products anytime and anywhere
.
Now that dreams are about to be reflected in reality, Wu Jieyang has not stopped his pace of innovation
.
In response to the impact of the epidemic, he and his team are developing a "contactless smart shared food cabinet".
Community residents can "order" at home to order fresh meat, fruits and vegetables, and the pre-ordered food will be placed in the community's "smart shared food" "Raise up" in the "cabinet" and take it as you go
