61 periods from the U.S. LSU dryers were produced locally for government warehouses and some big millers. A more popular design is the batch recirculating dryers imported from Taiwan, Japan and Korea although their construction is not rugged enough for the operating conditions of most millers and traders. The Bureau of Postharvest Research and Extension also developed a small, mobile pre-dryer called flash dryer to pre-dry paddy to 18% MC and to go with in-store bins following the in-store principle of deep bin dryers from Australia. However, farmers quickly rejected the flash dryer because of incomplete drying and its high kerosene cost while millers prefer shorter drying periods as more practical. Recently, government agencies collaborated through the Philippine Rice Postharvest Consortium (PRPC) to develop a batch recirculating dryer that can be locally manufactured for reduced cost compared to imported models. The resulting PRPC dryer is expected to be more suited to the operating and local paddy conditions in the Philippines. Rice milling Traditional milling is accomplished in the 1900s by hand pounding the palay in a concrete or wooden mortar with a wooden pestle called “mazo”. The first pounding takes off the hull and further pounding removes the bran but also breaks the grain. Further winnowing with a bamboo tray called “bilao” separate the hull from rice grains. This traditional hand-pounding chore allowed two to three men and women moving in to graceful harmony and is a form of socializing for romance and marriages in villages.
