New Vac-U-Vator Discharges 46,500-Ton Bulk Rice Cargo With Minimum Breakage A 46,500-ton cargo of rice was recently un-loaded in Korea and showed only an 0.8 per-cent kernel breakage for the unloading oper-ation. This exceptionally low kernel damage was attributed to a new Vac-U-Vator, devel-oped specially for rice. The successful results of this first discharge, and those to follow, should encourage the ex-portation of rice in bulk to emerging countries throughout the world. This large shipment was made on the Korea Rainbow, a seven-hold bulk carrier. Loading in Sacramento and San Francisco, four holds were filled with California Cal-rose rice and three holds held pearl rice. It was the maiden voyage for the ship. The vessel does not have any cargo handling gear other than the special Vac-U-Vator pneumatic rice unloaders. In Inchon, Korea, the entire cargo was dis-charged in slightly under 14 days, It was dis-charged completely into lightering vessels while at anchor. The free-digging rate of dis-charge was 50 tons per hour per Vac-U-Vator. The ship is equipped with six of the special machines, yielding a total discharge rate of 300 tons per hour. Including necessary time to clean up hatches, shift barges, and other de-lays, the entire vessel was discharged at an overall average rate of 3,321 tons per day. This was the second bulk cargo of rice to be discharged by pneumatic equipment at Inchon. The first vessel, which discharged about two years ago, had to discontinue unloading be-cause the cargo surveyor noted excessive grain breakage. The same surveyor inspected the discharge from the Rainbow. With the success shown on this voyage, the Korea Rainbow's next voyage will be a load of rice from the Gulf Coast to Korea. Dunbar Kapple Inc. feel that after years of discharg-ing pneumatically other grains, they have now developed a Yac-U-Vator which will prove as successful with rice. A. E.
