A Machine for Peeling Gingko (Nut from the centre of the inedible fruit of the Maidentree, used for cooking)
Luo Zeyao
Pizhou Jiangsu Province
Scout: Yang Peipei
Conventionally gingko is peeled by hands. But the method is time consuming and not very efficient. Mr Luo Zeyao has developed an electric machine to peel gingko. In the machine, there is a very thin and long knife which rotates continuously, and thus the flesh is peeled off the gingko. The work is done not only at a fast rate, but it is also very convenient.
The patent no. WO03070028 (Ryu Keun-Won, 2003-08-28) discloses a machine for peeling gingko nut, consisting of a space between a driving roller and a rack roller each having spiral grooves,
a flesh of gingko seed is discharged through the space between the driving roller and the rack roller, and the seed is discharged to a seed outlet by moving the seed along the driving roller and the rack roller.
Machine for Drying Sunflower Seeds
Wei Lei
Pizhou Jiangsu Province
Scout: Yang Peipei
The seeds of the sunflower are conveniently dried in a machine. The washed seeds of sunflower are put into the machine on different platforms. The machine uses electricity to generate heat, which dries the seeds. It consists of a handle to stir the seeds continuously so that the seeds are heated and dried from all sides uniformly.
The patent no. UA14956U (Vitaliiovych et al, 2006-06-15 ) reveals a sunflower seed dryer consisting of a welded frame, fans, air ducts and working units, infrared radiators, sieves, diffusers, inlet and outlet spouts. It works on the principle very much similar to the one described in the above invention.
Improvement in the Plough
Huangzhong County, Qinghai Province, Wu Zhuang
This is a modified plough with a metallic triangular frame. The frame comprises spike-like protrusions and is fitted on to a tractor for ploughing purpose. It is used for ploughing
hard soil.
Improved Hoes
Han Guan Le
Laizhou City, Shandong Province, Disabilities Town Tan Village
Scout: Han Feng
This is a hoe that is attached to the front half part of a bicycle. Only the front wheel and the handle of a bicycle are used. Thus a broken bicycle is put to use, while at the same time making hoeing an easy, less energy consuming job. There are many such agricultural implements that use one or the other part of a bicycle to save energy.
Shri Gopal Malhari Bhise, a farmer of Shendurin village situated in Jamner Taluka of Jalgaon District, had fixed a rod with a blade at the end, to an assembly consisting of only the front-wheel and the handle of a bicycle. He has named the assembly as Krishiraja, and claims it to be extremely efficient in removing weeds from hard land (Honey Bee, 11(4) & 12(1): 15; 2000-2001).
Radish Preservation in Winter
Pingyin County, Shandong Province Town, Takanao
Tian Yan-Ting Liu Guodong.
This is an innovation for keeping the carrots fresh in winter. First an area, in land which can hold moisture is chosen. A pit is dug and carrots are put inside it. The pit is then completely covered with soil. Dry corn-stalks are then inserted into the pit. Corn-stalks are hollow inside and thus would aerate the carrots stored and keep them fresh.
To preserve carrots they are buried in lightly moist sand in an underground cellar or stored in the garden in a pit insulated with straw. Under proper storage conditions, carrots remain fresh for four to six months. (http://www.urbanext.uiuc.edu/veggies/carrot1.html); Dudhabhai Arjanbhai Pandav of Genol village in District Ahmedabad follows a special method to preserve wheat. Approximately 2-3 feet deep pits are dug in the house/store room. The bottom of the pit is covered by a thin layer of wheat husk and filled with wheat. Each layer of wheat is alternated with a thick layer of husk and finally covered by soil (Honey Bee, 3(1):13, 1992).
Making Coal from Straw
Chen Hong Wei
Zhou Kou City, He Nan Province
Coal is formed from lumbers at high-temperature, high-pressure and aneroxic conditions. Chen Hong Wei, a peasant, has developed a technology to make coal and coal balls from straw, bamboo and lumber. He has spent three years on research, and has conducted hundreds of experiments based on the law of conservation of energy, using chemistry additives under artificially controlled conditions to finally develop the technology. He has named it Solidified Molding Technology.
The patent no. CN1944601 (Shen Changbing, 2007-04-11) is a complex catalytic physical and chemical process of coalifying stalks. The process includes the following steps: forming coalifying apparatus; spreading stalks with catalyst; igniting while spraying cold water for carbonizing the stalks into charcoal; mixing the charcoal, potassium dichromate, and water to form artificial coal; and forming to obtain environment friendly fuel. The coalified fuel may be used widely in industry and household.
Fly Catcher

Ten years back Hu Xilin was having dinner with a client, and a big fly was found in the food just before the deal on a huge contract was about to be closed. The client got upset and left. Hu was determined to develop a design to catch flies. Thus began his efforts to innovate something.
The machine innovated by him emits sound waves which attract flies from a certain distance. It comprises rollers covered with fly killing solutions. Following the sound waves the flies fly into the rollers and get killed. It took Hu more than 10 years to develop this machine and it has helped in killing millions of flies.
A wide variety of electronic fly catchers are available in the market, of particular interest is an electronic fly-swatting device based on the idea of the Venus fly trap.
