Abstract

In order to obtain the better mushroom drying operation, it requires proper information of its equilibrium moisture content (Me) and drying constant since it was very useful for storag.The objective of this research was to design  Me and K models.The models were function of drying temperature and designed based on infinite slab and sphere geometry.The experiments were conducted at 35,40,45,and 50 degree C,on blanched/unblanched condition and were operated at drying air velocity of 1.0 1.5 2.0, and 2.5 m/s.The Me and K models based on infinite slab gave better results.

Abstract

Data relating to physical properties and characteristic of dried mushroom was very useful information especially for packaging, storage, and transportation purposes. The objectives of this study were to investigate some physical characteristics covering, rehidration coefficient, shear stress, as well as rendement of mushroom affected by drying. The drying experiment were conducted at 4 level temperature (35 derajat celcius, 40 derajat celcius, 45 derajat celcius and 50 derajat celcius), and level 4 drying air speed (1 m/sec, 1.5 m/sec, 2.0 m/sec, and 2.5 m/sec) with and without blanching treatment. Dried mushroom with blanchead treatment gave better rendement (aximum 12,67%) and shear stress value (maximum 18954,00 Newton/m2) comparing with those without blanched treatment. In the other hand dried mushroom with blanched treatment showed better appearance and rehiration coefficient (maximum 4,31) than those without blanched treatment.
