Winnowers yield. Cacao Cucina ® winnowers typically yield 75%-80% good nib from the roasted beans fed into the breaker, with less than 1.75% shell and less than 1% fines. Bean origin, bean size, bean shape, breaking temperature and operator efficiency will have an effect of final yield.
The Vortex winnower uses centrifugal forces to differentiate between the high and low kinetic energy particles suspended in the swirling gas stream. This causes the particles, which are denser than the gas, to move outward to the vortex tube wall, along which they are transported downward to the reservoirs.
May I present the new leaner, meaner Aether Winnower. This product of seven years observation, three years prototype work, thousands of pounds of cracked and winnowed test beans, and not a small amount of alchemical inspiration, is hand built in stainless steel (the 50 lb .
The Sylph winnower is the product of eight years observation, four years prototype work, thousands of pounds of cracked and winnowed test beans, and not a small amount of alchemical inspiration. It is powder coated aluminum (the frame) and food grade PVC (the air flow/bean/nib path). It is a hand fed winnower .
