.. r. ._ l cleaning grain samples received from plot combines and threshers. As these samples often contain 60 to 70 percent chaff and straw, an air aspirator is used to remove this material first. The semicleaned sample then passes over a double sieve-cleaning riddle. Capacity is 25 samples per hour, based on samples received from the N.I.A.E. plot combine.

CeCoCo Paddy Separator

Because of the different sizes, shapes, and degrees of maturity of grain, no rice huller can hull every paddy completely in one operation. Any attempt to hull all of a paddy will result in excessive breakage. When a mixture of hulled and unhulled rice is fed into the hopper or separator, it glides down along the surface of multistaged, inclined wire screen and separates the rice into four kinds: (a) completely cleaned, hulled rice, (b) unhulled rice, (c) unripened and imperfect rice, and (d) broken rice with mui sand, or dust. It is also used for sorting the polished rice for grading. It is made of hardwood and can be dismantled and folded down for storing. Wire screens of different sizes are furnished to meet varying needs. It will separate paddies at a rate of about 70 bushels per hour and also grades brown rice.

CeCoCo Bean Cleaner and Separator

This unit is specifically for use with the red bean and other round-shaped beans. The input funnel is equipped to regulate an even How of beans to the first separating device, which removes impurities, husks, and dust, and onto the second separating plate, which removes imperfect or immature beans. There are provisions for adjusting the machine to fit the specific bean being cleaned.

CeCoCo White Rice Cleaner

Using the difference in weight between grains and the accompanying impurities, this machine will separate rice from dust, sand, stone, grit, and other foreign substances. The machine is light; the heaviest of the four models weighs 110 kilograms. Also, it requires only ]/l a to y2 h.p. to operate.

IRRI Power Grain Cleaner

The Power Grain Cleaner uses rotary screens in conjunction with an air blast. This combination simplifies the design and permits extended exposure of a tumbling mass of grain to air, resulting in improved cleaning.

It is ideally suited for tropical countries and was designed particularly for rice mills, farms, warehouses, and experimental stations. The grain is cleaned by means of two concentric cylindrical screens. The inner screen retains large impurities but lets the grain through.

Smaller impurities like sand, dust, and weed feeds pass through the outer screen. This cleaner has ait adjustable air opening lor quality cleaning and an adjustable feeding rate. The three pulley settings result in approximate cleaning capacities of 1.6, 2.0, and 2.5 metric tons per hour by powering with a 1 h.p. electric motor.

Small-Scale Seed Cleaner

Farmers have been inventors for hundreds of years. As long as there are jobs to be done, individuals like Tim Sanford of Alexander, Maine, will be devising easy, inexpensive tools like his seed cleaner.

The cleaner, which uses a vacuum cleaner, a plastic snap-cover pail, a funnel, and a mailing tube, can clean over 100 pounds of seed per hour, though we wouldn't recommend it for anyone with over 1,000 pounds of seed to clean. "It works quite well, but not perfectly, for wheat and our seeds," Sanford explains.

To operate the seed cleaner, a steady stream of the grain to be cleaned is poured into the funnel. If it clogs, a thin stick will unclog it.

Adjust the airspeed (the vacuum should be blowing into the bucket) so the good seeds (the heavier parts) will be just heavy enough to escape being blown from the chaff holes at the top and will fall to the bottom. The inner tube (Sanford uses a cardboard mailing tube) can be made smaller to get more force from a vacuum cleaner with low pressure.
