Abstract

The objectives of this study were to determine a suitable thin layer drying model to describe the drying kinetics of Guazuma ulmifolia leaves and determine the mass transfer parameters of Guazuma ulmifolia leaves. The drying of Guazuma ulmifolia leaves was conducted in a laboratory scale dryer with various temperature (40oC, 50oC, and 60oC) and relative humidity (30%, 40%, 50% and 60%). Five drying models, namely, Newton, Henderson and Pabis, Page, Midilli-Kucuk, and Verma et al. were fitted to the drying data. The drying curve of guazuma leaves did not show a constant drying period during the drying period. The models suitability were compared base on coefficient of determination (R2), root square mean errors (RSME), and reduced mean square of deviation (X2). It was found that, among the models evaluated, the Midilli and Kucuk model is the best to describe the drying kinetics of Guazuma ulmifolia leaves. The effective moisture diffusivity was found to be in the range of 10-13 – 10-12 m2/s and the convective mass transfer coefficient was in the range of 10-9 – 10-10 m/s. The activation energy value was found to be 89.21 kJ/mol.

Abstract

Size reduction applied on Arabica Coffee bean may change its physical properties, where these properties are utilized for designing process including packaging and appliances for further processes. This research aims to investigate physical characteristics of Arabica coffee powder with addition of corn and rice milled through mechanical process. This experiment used two mechanical mills including hammer mill and disc mill. Before it is milled, coffee was mixed with other materials including corn and rice. Parameters observed were yield, moisture content, bulk density, and angle of respose, particle uniformity index, fineness modulus, and the average particle dimensions. Based on the results obtained, it was revealed that moisture content of each test still meet SNI standard with the maximum of 7%. Bulk density of coffee powder resulted using disc mill was higher compared with hammer mill. However, particle generated from milling process may be categorized as powder with medium cohesiveness based on its angle of repose. Dimensional average particle is proportional to the fineness modulus of coffee powder produced. Highest fineness modulus obtained from coffee powder without additives, and using a hammer mill is equal to 4.37 with the highest average dimensions of 2.05 mm, while the lowest fineness modulus that the coffee powder without any additional ingredients milled with a hammer mill is equal to 4.22, with the lowest average dimensions of 1.94 mm.

Efficiency Analysis in Drying System for Rosella (Hibiscus sabdariffa L) Using Cabinet Type DryerABSTRACT. Drying is one of the most important process in producing a good quality of rosella tea. The study was aimed to evaluate the drying efficiency of rosella tea by using a cabinet dryer. The source of energy for the dryer was from the burning of charcoal. The charcoal was prepared from the coconut shell since it was abundant biomass product. About 7.5 kg of fresh rosella flower was dried for 17 hours. The total of charcoal consumed was 17 kg. The moisture content of rosella flower was reduced from 90 to 12 %. The analysis showed that the total of energy produced from the burning of 17 kg charcoal was 309.4 MJ, whilst the total energy needed to dry the flower was 15,72 MJ. Therefore, the drying efficiency was still low about 4.58%. Further study is recommended to improve the drying efficiency for example by the use of deeper depth of dried products between 2 and 6 cm as well as by improving the system of hot air circulation.

Cassava is one of the plants that contain carbohydrates. Cassava can be dried to produce processed products such as cassava flour and “gaplek”. In this research, the solar dryer was modified by adding a savonius windmill as fan drive which aims to maximize the air circulation inside the drying chamber. The observed parameters include air velocity, the distribution of temperature, relative humidity, solar irradiation and the water content. The addition of savonius windmill caused the air velocity in the solar dryer was more stable when compared to the speed of the air in the environment. Moreover, the temperature in the drying chamber was higher than the ambient temperature, while the relative humidity in the dryer was lower than in the environment. As a result, it caused rapid drying process. Solar irradiation values obtained fluctuate. The highest irradiation was obtained on the second day of the study (595 W / m2). The moisture content of the cassava decreased from  61.7% to 11.7% (at A5 rack) and 12.9% (at B1 rack). Those values was approaching the expected flour water content (12% ).
