摘要

A process of producing mustard oil of a high degree pungency wherein;the mustard seed is first pulverised in a pulveriser; the pulverised mustard seed is put in a steam bath and subjected to mechanical agitation, characterised in;that the said seed is then pressed in one or more double chamber expellers which are provided with hollow worms;and that the said hollow worms are maintained cool at temperature between 30 degrees Celsius and 40 degrees Celsius by a flow of chilled water through them and recovering the extracted oil by known means.An apparatus for producing mustard oil of a high degree pungency comprising:a pulveriser which is a horizontal drum with perforated sheet at bottom and replaceable jolleys of different sizes of perforation, and is provided with knife edged beaters;one or more chambers provided with steam inlet and pipes,the said chamber or chambers having a common central shaft provided with a number of radial rods with flat tops at different lengths which are capable of rotation at different levels inside the chamber or chambers;one, or more oil expellers, each of the expellers being a coaxially placed two chamber unit having a central hollow shaft on which are fitted hollow worms.
