Chapter 2
Industrial Plant Oil Extraction
Zhihong Xiao, Rukuan Liu, Hong Wu, Qiang Liu, and Changzhu Li
Abstract This chapter is concerned with industrial plant oil extraction from oilseeds.
It includes a brief account of the principle of oil extraction, storage and preparation
of oilseeds, mechanical extraction, solvent extraction, and oil refining. Different purposes of use between edible plant oil and industrial plant oil have led to the different
technology, crafts and equipments during each production process. The industrial
plant oil extraction has a history, but it did not form a systematic theory and mechanism. How to get a suitable industrial plant oil is the first step. So far, the industrial
plant oil extraction is similar to edible plant oil. For example, the solvent extraction
process consists of the unit operations of solvent extraction, meal desolventizing,
meal drying and cooling, miscella distillation, and solvent recovery. Finally, some
novel technology and equipment of oil extraction about especial oilseeds are provided
and discussed.

The oil extraction from oilseeds involves some steps, depending on the particular
commodity to be processed, the scale of operation, and so on. In the early days,
industrial plant oils were extracted by pressing, and the functions were often little consideration on the impacts made by subsequent processes. At present solvent
extracting method has been widely used in the oil industry. Extracting process has
