FIELD OF INVENTION
This invention relates to a unit for production of- bio diesel using bio fruits.
BACKGROUND OF THE INVENTION
It is known that, Seeds of pongamia fruit are utilized for bio-diesel production, wherein fruits are decorticated. Decorticated seeds are used for crude oil production. Outer shells are used for burning and cakes are used as manure. As known by study, Pongamia fruits have outer shells (50%) by weight and seeds 50% by wt. out of 50% of seeds, only 35% is converted into vegetable oil and remaining 65% into cake. Cake is presently used as manure and shells are being burnt for heating purposes. Therefore, out of 100% fruits, only 17% energy is recovered and rest 83% is not utilised. Therefore, it becomes necessary to upgrade the existing bio-fuel production technology to an integrated technology so that maximum (%) of energy content from the fruits can be recovered. Recovered energy (power) can be utilized during bio-diesel production and surplus energy can be used for other purposes.

The present invention relates to a unit for production of bio diesel using bio fruits for biodiesel production utilizing upto 83% of energy from Pongamia fruits instead of existing utilisation of 17% of energy. This unit can be used for extracting the energy available in outer shells/cakes of fruits to produce producer gas. The gas is used for producing power by SI engines and the power generated by above is used for driving decorticator & crusher. The remaining power can be used for other purposes. The hot exhaust gases of engine can be used as heat energy resource for heating the bio diesel reactor and drying the outer cells to bring the moisture content below 15%. The present invention utilizes outer shells (wastes), cakes, gasifier, SI engines/generator, bio-diesel reactor, drier and converts 83% of bio resource energy from bio-fruits instead of existing upto 17%.
BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWING
Further objects and advantages of this invention will be more apparent from the ensuing description when read in conjunction with the accompanying drawing indicating exemplary embodiments of the present invention and wherein:
Fig. 1 shows: unit of the present invention for production of bio diesel.
DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWING
This invention discloses a unit for production of bio-diesel in which power requirement for the process is met by the unit itself. For this, outer shells and cakes of Pongamina fruit are utilized to obtain useful producer gases namely hydrogen, carbon monoxide, methane & other hydrocarbon gases. These gases are used to drive the spark engine for producing power.
Although, biomass has complex composition, it is basically considered as being composed of three major components namely cellulose, hemicellulose and lignin. These components together form up to about 90% of the dry weight of any biomass material. According to the plant source, the balance is ash (5 to 10%) and small amounts of numerous minor organic materials such as proteins, tannins, essential oils, waxes, pitch etc. If the energy of the biomass is extracted by direct burning, the energy content varies depending on moisture content and other factors.
Thus, outer shells are biomass having bundle of energy. Keeping this in mind detailed proximate analysis of outer shells are carried out and found the following : bulk density (kg/m3) = 223.09, angle of repose (0) = 25.03, moisture content = 8.43, inherent moisture (% wb) = 5.42, volatile matter (%db) = 64.57, ash content (%db) = 6.18, fixed carbon (%db) = 20.82 and gross calorific value (k cal/kg) = 4176. As inferred by data, outer shells have good bulk density, flow properties and calorific value. Hence, it is established that this shell is good fuel and good for thermal gasification in down draft gassifier. The main objective is to produce a low BTU producer gas.

The unit as shown in figure 1 comprises a decorticator (1) for decorticating the seeds from outer shells connected to an extractor (2) for extracting oil from the seeds. The decorticator is also connected to a biomass drier (3) so as to dry the outer shells and oil cake. Dried outer shells are fed into biomass gasifier (4) connected to the dryer so as to gasify the waste to produce producer gas supplied to gas cooling & filtration system (5) used to cool the hot gases followed by filtration. The cooled gas is fed into SI gas engine/generator (6) to produce power. Power thus produced is supplied to run the engines of decorticator & extractor. The remaining power is utilized for other purposes like lighting. The exhaust of the SI engine is used for drying the outer shells and heating bio diesel reactor (7).
This unit extracts energy from the unused energy of the outer shells of the fruits. Thus, the above unit can make use of atleast 87% of energy from bio-fruit instead of existing 17%,
