Jojoba seeds were successfully milled at ambient temperature using a modified 8 in. single disk attri‐tion mill. Rates to 4000 lb/hr at low energy input (1.7 kwh/ton) were achieved. The oil was expressed with a laboratory screw press at yields from 27. to 33.6%. Multiple linear regression analysis showed the oil yield to be a function of the motor amperage and feed moisture content. The press throughput rate was a function of the motor amperage and the amount of fine and coarse particles in the milled feed.
