Production Engineering

  Castor seed through conveying equipment into the warehouse, after the active measurement into the buffer tank, and then evenly feed the vibrating screen clean up impurities, clean the impurities of castor seeds in the chute, after the electromagnet and permanent magnet to iron, by the elevator into the pan, adjust the squeezed water and temperature, in the rolling PI machine for crushing processing. Then it is fed by the quantitative winlong into the oil press.

The pressing factors affecting the oil yield of castor bean

  The pressing temperature and pressing time are important factors affecting the oil yield of castor bean.

(1) The content of castor oil in castor bean seeds is 47%, and the protein content is nearly 20%. The characteristics of high oil content and high protein content often lead to the conventional spiral pressing, which is easy to the oil production. In order to obtain high quality castor oil and ensure the activity of protein in castor seed, the proper control of the pressing oil is essential, so it is necessary to adjust the raw state of castor bean seeds according to the demand. Theoretical calculation shows that the optimal preheating temperature of castor seed pressing oil is 70.8 9C, which is similar to the optimized actual feeding temperature, and the oil yield reaches 62%.

(2) With the increase of temperature, the viscosity of castor oil is significantly reduced, which has stronger fluidity, reduces the friction between the pressing cavity, reduces the pressure between the fluid, and then improves the efficiency of oil production, and also solves the phenomenon of slip during spiral pressing. At 70 C, castor oil has a lighter color and a reduced acid value with a higher quality.
