In an expeller, raw material is squeezed or pressed with an oil press under high pressure in a single step for the extraction of oil. Friction or continuous pressure is employed to move or compress the algal cells, which breaks their cell wall. This method can extract around 75% of oil present in biomass. To ensure good efficiency, algae must be dried before the extraction of oil. No purification is required as it does not require any solvent (Popoola and Yangomodou 2006). Because there is a variety in physical attributes of different algae strains so various press configurations (screw, expeller, piston, etc.) are used for specific algae types. A limitation of this method is that it needs algae in dried form, which is energy intensive. It is also a slow process.

Industrial boilers from 100kW to 10MW burn waste wood such as wood chips, sawdust, cuttings, or farm waste (straw, grasses, oil press cake, legumes, etc.). Burning is facilitated by mechanical grates, cyclone furnaces and fluid-bed reactors. Firing is of the continuous type, either mechanical or pneumatic. Due to lower specific bulk density of straw, wood chips, etc., larger storage sites are required for these fuels. On a less frequent basis, briquetting is used, as well. Burning straw, the so-called “cigar burning” process is deployed to combust bulky straw bales. Biomass burning residue is harmless ash that can be returned back to nature (fertilization, high potassium content).

The BaSO4 particles before and after dissolving were mixed with 200 mg of dried KBr, and then fully ground and placed in a grinding tool. The samples were pressed into transparent flakes using an oil press, and the obtained samples were placed in an infrared spectrometer for testing.
Statistical optimization and kinetic study on biodiesel production from a potential non-edible bio-oil of wild radish

Wild radish seeds were collected from Nilgris district, Tamilnadu, India. The samples were identified and authenticated as Raphanus sativus by Agriculture University, Coimbatore, Tamilnadu, India. It is a perennial plant of the Brassicaceae family that is widely grown throughout the world. The extraction of oil from the seeds was accomplished by mechanical pressing using a spiral oil press extractor (140CJX Model). The impurities from the extracted oil were removed through sedimentation process and filtered through steel mesh. Chemicals and reagents like methanol, KOH etc. were obtained from Merck, Mumbai, India.
