Abstract: The present invention relates to a Fuel Supplement comprising of selected plant oils mixed in given proportions, which when added to fuels like petrol and diesel can reduce harmful emissions during combustion of fuel. It can significantly decrease the Sulphur content in fuels and thus protect the environment from harmful pollutants. It improves the fuel lubricity and engine performance. It also increases the flash point of Diesel.

Abstract: Soybean dehulling, blanching and grinding apparatus is provided for preparation of a relatively coarse ground slurry consisting of water and approximately 12% by weight of bean tissue. Soybeans having a moisture content of approximately 13% are dehulled in a rapid and efficient manner and without crushing or grinding the cotyledons. After separation from the hulls, the whole cotyledons are blanched by dropping the same in boiling water without prior soaking. The blanching apparatus blanches the cotyledons rapidly and without producing excessive foaming. The blanched soybeans are then mixed with water and ground in a horizontally positioned grinding tube by means of a series of blades which also move the product along the tube while providing a uniform mixture of bean tissue and water. A screen is provided at the end of the tube which prevents the issuance of material until the solids have a desired size, as determined by the perforations in the screen.
