Dehydration of Soybean Residue by Hot - air in Conjunction with Filter Pressing
|

Abstract
|
|
|
The wet soybean residue, a byproduct of soymilk industry having potential food value has been tried to dehydrate for the purpose of storage. The total solid of the byproduct was composed of 28.9% protein, 13.6% fat, 4.4% ash and 53.0% carbohydrates.
The original water content of 593%(dry-weight basis) was reduced to 378% by pressing mechanically. The sufficient pressure and time for the pressing were found to be 0.5M/T and 5minutes, respectively.
The partially dehydrated soybean residue was formed into pellets of 3㎜ in diameter and 10㎜ in length. By applying hot air on the thin layer of pellets the moisture could be further reduced to the level of 10% which is equivalent to that of the commercial wheat flour. No significant color deterioration in the product was observed if the hot air dehydration procedure was within the limit of 95 minutes at 120℃ under the air flow velocity of 160 feet per minute.
