Abstract

Temulawak (Curcuma xanthorrhiza Roxb.), a member of the Zingiberaceae family, has long been recognized as a medicinal plant with a moisture content approximately 80-90%. The high moisture content of temulawak renders it challenging to store for extended periods without drying. Temulawak is susceptible to heat damage due to the potential for thermal degradation of its internal components. Accordingly, it can be concluded that low-temperature and low-air-humidity drying conditions are required. Furthermore, one of the most suitable methods is the use of a dryer that incorporates a dehumidification process. The objective of this research is to develop a temulawak dryer design and simulation variations of the incoming velocity of air flow to obtain the most optimal drying chamber by incorporating a vertical airflow channel. A design and simulation for a temulawak dryer were created using the 2022 version of SolidWorks software (flow simulation modul). The design started from drawing two-dimension, then three-dimension, and determining boundary condition and meshing. A fluid temperature of 35.7°C and a relative humidity (RH) of 22% were used to model the drying process at varying airflow velocities of 1.5 m/s, 2 m/s, and 2.5 m/s. The drying chamber, with dimensions of 676 mm x 406 mm and height of 806 mm, was designed using the type AISI 304 and achieved the most optimal airflow distribution results at a velocity of 2.5 m/s, exhibiting a relatively higher fluid temperature than the other two airflow velocity variation.

Abstract

Sistem pengeringan merupakan salah satu alat pengolahan pasca panen yang banyak digunakan untuk memperpanjang umur simpan/mengawetkan, dan mempertahankan kualitas produk. Salah satu bentuk atau model pengering yang banyak digunakan adalah tipe rak bertingkat (tray dryer). Kualitas produk yang dikeringkan sangat dipengaruhi oleh distribusi temperatur (suhu) yang terjadi dalam ruang pengering. Tujuan penelitian ini adalah menganalisis pengaruh jumlah saluran udara masuk terhadap distribusi suhu pada ruang pengering. Disimulasikan 3 model atau jumlah saluran udara masuk yakni: satu saluran (model-1), dua saluran (model-2), dan tiga saluran (model-3). Pembuatan Model dan simulasi menggunakan perangkat Lunak SolidWorks (flow Simulation). Laju aliran udara pada setiap model pipa saluran masuk adalah 0.5 m/detik, dan suhu elemen pemanas (heater) 200 oC. Hasil simulasi menunjukkan bahwa dari ketiga model tersebut menghasilkan distribusi temperatur yang merata dengan baik adalah model-2, dibanding model-3 dan model-1. Pada model pipa-2 rentang suhu pada ruang pengering terendah dan tertinggi hanya 2,21 oC, sementara pada model saluran pipa-3 sebesar 7.95 oC, dan pada model pipa-1 terdapat rentang suhu sebesar 12.9 oC. Jumlah pipa saluran masuk sangat mempengaruhi distribusi temperatur/suhu pada ruang pengering
