Q1: Bollman extractor

ANS:B - is used for extraction of oil from oilseed.

The correct option is: is used for extraction of oil from oilseed. Explanation: A Bollman extractor is a type of equipment used specifically for the extraction of oil from oilseeds, such as soybeans, sunflower seeds, or rapeseeds. It is commonly employed in the oilseed processing industry to extract oil from the seeds through a mechanical extraction process. The Bollman extractor typically consists of a cylindrical vessel containing a rotating screw or auger that crushes and presses the oilseeds to release the oil. The extracted oil is then separated from the solid residue (meal) using various separation techniques, such as filtration or solvent extraction. While counter-current extraction and centrifugal extraction are common techniques used in extraction processes, they are not specific to the Bollman extractor. Similarly, the Bollman extractor is not typically considered a static bed leaching equipment; instead, it operates through mechanical crushing and pressing of oilseeds.
