Abstract

This study aims to design and build a cabinet-type breadfruit chips dryer powered by liquefied petroleum gas (LPG) and to assess the dryer's characteristics, particularly by observing the temperature and relative humidity (RH) variables in the drying chamber. This characteristic data is critical for forecasting the dryer's ability during drying. The experimental approach was carried out in three stages: design, assembly, and testing without a drying load under two process conditions, charging and discharging. The testing time is 150 minutes, with the charging procedure taking 70 minutes and the discharging process taking 80 minutes. In general, the distribution of temperature and RH on each shelf in the drying chamber is consistent, both during the charging and discharging processes. In the charging-discharging process, the average temperature of the drying room is 45.39 C with a RH of 40.99%, while the plenum room average temperature is 77.02 C.

Abstract

Pengeringan merupakan salah satu metode pengawetan yang paling banyak digunakan untuk memperpanjang masa simpan produk pertanian, makanan, dan bahan lainnya. Penelitian ini bertujuan untuk merancang dan membangun alat pengering skala laboratorium yang inovatif dengan integrasi thermal energy storage (TES) berbasis phase change material (PCM) menggunakan paraffin wax sebagai media penyimpanan energi. Metode yang digunakan meliputi desain alat, perakitan, dan pengujian performa. Paraffin wax dipilih karena sifatnya yang mampu menyimpan dan melepaskan energi panas secara efisien pada rentang suhu pengeringan yang dibutuhkan. Penelitian ini secara khusus mengevaluasi kinerja termal dari alat pengering untuk mendapatkan karakteristik sistem berupa distribusi temperatur di ruang pengering, distribusi temperatur pada media TES, dan distribusi temperatur udara keluar alat pengering melalui cerobong. Hasil investigasi menunjukkan bahwa penambahan TES berbasis PCM paraffin wax mampu menjaga stabilitas temperatur di ruang pengering. Hal ini nantinya akan berdampak positif pada efisisensi sistem secara keseluruhan.

Abstract

Cabinet-type dryers powered by Liquefied Petroleum Gas (LPG) are widely recognized as an efficient drying solution, particularly for small and medium-sized industries. However, the structural strength and durability aspects of these dryers often receive insufficient attention, although they operate under a combination of static and thermal loads that may potentially trigger structural failure. This study aims to evaluate the structural strength of a cabinet-type LPG dryer using the Finite Element Analysis (FEA) method by considering variations in operating temperature and constant mechanical loading. Simulations were conducted within an operating temperature range of 48.049°C to 75.767°C under a constant load of 40 kg. The key parameters analyzed include total deformation, stress distribution, and structural safety factor. The results revealed a maximum deformation of 1.094 mm and a peak stress of 1030.7 MPa concentrated in the plenum chamber area, identified as a critical zone due to the combined effects of thermal and mechanical loading. The maximum safety factor reached 15, while the minimum value of 0.24255 indicates the need for localized design improvements in certain regions. These findings demonstrate the effectiveness of FEA in predicting the structural response of drying equipment and provide a scientific foundation for enhancing structural safety and reliability. Further studies are recommended to integrate coupled thermal-structural analysis and experimental validation to improve the accuracy of the results. Keywords: cabinet dryer; finite element analysis (FEA); safety factor; structural analysis; temperature distribution
