1、 belt conveyer section through storage building oil seed oil seed bulk cleaning foreign materials delinting for cottonseed lints dehulling hulls flaking cooking moist cleaning cleaning is important not only to ensure the good quality of the final products oil and meal but also to avoid premature wea

2、r of the preparation equipment. the removal of foreign materials from oil seeds is done by cleaning machines working on mechanical, pneumatic and magnetic principles. cleaning machines; screens aspirators magnets shape sorters drum screen seed inlet aspirator rotating drum stationary magnet ?ron par

3、ts cleaned seed cottonseed lints (8-12%) hull (40-45%) delinting process to remove the remaining lint from cotton seed aims of delinting : 1)increase oil yield 2)obtain first- and second- cut linters cottonseed saws brush delinted seed cut lints seed feeder saw teeth seed bars (concave surface 1/3)

4、square-edged knives seeds rotating disc stationary disc adjust according to seed size flaking the extraction of oil from oil seeds, either by mechanical extraction or solvent extraction, is facilitated by reduction of the seed to small particles. flaking is achieved on corrugated roll stands. cracking mills with one or two pairs of rolls are used. hammer mills are used for certain raw materials like palm kernel. corrugated roll speed 0.05 m/sec knife smooth rolls kernel flake crushing rolls direct steam sweeper-type stirrer exhaust pipe t (0c) cooked flakes seed flakes gate
