Product Benefits
Keep You Cool
It actively removes the hoe, stagnant air from the attic while allowing the cooler outer air to enter, reducing the indoor temperature considerably. In the process, it also lowers the surface temperature of the attic flooring and prevents the hot air from seeping through to the living area.
Defend Your Roof
The most significant benefit of attic ventilation is that it offers the roof and ceiling much needed protection against heat and moisture,helping preserve their structural integrity. Built-up attic heat can cause trauma to your home's roof and internal structures putting a major dent in your wallet. A solar fan helps preserve the integrity and beauty of your home by venting hot air before it does any harm.
Pocket Your Cash
Everything comes at a cost except solar attic fans. They run using the sun's energy, so you won't pay a dime for electricity. You also won't need to hire an electrician because there's no wiring. In  the spring and fall, you may not need air conditioning at all! And, since it is all powered by the sun, you will get these benefit at no cost to you!
Keep House Dry
Moisture is just as damaging as heat. During the winter, warm water vapor from showers, dishwashers and humidifiers rises and accumulates in your attic. It condenses as it contacts cold surfaces there, eventually soaking into the wood and insulation. If left as is, it could rot your wood framing, reduce your insulation's effectiveness, and spur mold and mildew growth. Keeping your attic dry with a solar attic fan can help you avoid hefty repair bills.
Quick and Easy
It only takes about two hours to get your new fan. Units come ready to install, so there is no complicated assembly required or big construction mess to clean up. Once your solar attic fan is installed, you can leave your ladder in the garage. It's designed to be maintenance-free, so you won't have to make any trips to the roof for servicing.

Grain cleaning machine Gravity Stone Remover
after raw material cleaning in grain processing plants, to grading grain, concentrate to clean impurities, (such as blighted wheat, small corn cobs, etc.) and to remove sand, mud. It use wind, vibrating and sieving effect matching technology, to be high efficiency, great performance on grading and separating gravel, mud pieces, low power consumption, no dust leakage, low noise, easy operation and maintenance.
Features
1. Advanced design and excellent fabricating
2. Reliable and excellent stone separation and efficient cleaning
3.High specific capacity
4. Easy operation and maintenance
5. Two options: with or without air-recycling system.
6. A fan is equipped on the air-recycling type and a special separator is installed ahead of the fan. The separator deflects the aspirated air through a lamellar system so that dust and chaff are separated from the air and dischar
ged by an airlock valve while the cleaned air is recycled by the fan in the air return pipe to the destoner
Application
1.The machine is designed for separating stones from a continuous product stream
2.On the basis of differences in specific gravity, reliable removal of highdensity impurities such as stones and pieces of metal and glass is achieved.
3. Versatile application in flour mills, rice mills, feed mils and seeds selection processing.
Principle
1.The sieve box which is normally equipped with two layer sieves is supported by hollow rubber springs and is caused to oscillate by one or twovibrators depending on machine execution.
2.The grain is spread by a feeder across the entire width of the machine, and then the product stream is stratified on the pre separation screen according to its specific gravity by the oscillating motion of the screen and by the air flowing through the product from bottom to top. The light particles collect at the top, and the heavy ones including the stones at the bottom.
3.The lower layer with the heavy particles flows upward and is fed to the final separation zone of the bottom de-stoning screen. Final separation of the stones from the grain is accomplished by a countercurrent of air.
4. The stone free product streams on the two screens float on cushions of air, flowing slowly toward the product outlet, and then are discharged through the squeezed rubber valves.
5. To achieve the optimum degree of separation, the inclination of the screens, the air volume and final separation can be adjusted accordingly.
The process of flour milling:
The process of flour milling (from corn to milled into corn flour) usually consists of the following:
1. corn storage (silos, or warehouse)
2. cleaning system (sifter, destoner, seprater, magnet, scourer, etc)
3. dampening (dampener, conditioning silos, etc)
4. milling system (roller mill, plansifter, purifier, impact detacher, etc.)
5. Flour pressure and blending system (if need)
6. flour packing and stacking
The complete sets of oil equipment that we manufactured, relying on many domestic scientific research institutions. Advanced technology, suitable for making all kinds of plant oil. From the raw material of cleaning up, prepressing, leaching, refining and the production processing of by-product (such as Phospholipids engineering, protein engineering), is totally a dragon design and production, has created considerable economic benefit and social benefit for the user and society more than 40 years. Company new development of biodiesel equipment technology in recent years, has put dozens of sets on the market, obtaining good economical benefits both In the domestic and overseas. At present, we have hundreds of successful installation operation of the oil equipment engineering experience, can design and product according to the difference of the user's economic condition. raw material. regional, install oil equipments.
YongSheng comapny with scientific management method, strives for perfection the manufacturing process, innovative manufacturing idea, fast grows and become the grain and oil machinery production and export base in China. Company products are exported to Russia, India, Nepal, Indonesia, South Africa,Tanzania,Ethiopia,Ukraine, kazakhstan, Pakistan, Iran, north Korea, Vietnam, France and the European Union and so on more than 30 countries and area.
