Design Specification

One way of processing agricultural products is by drying process. It  is a process of reducing water content to a certain extent so that it can inhibit the rate of damage to agricultural products (rice) due to biological and chemical activities. Drying is the last step in a series of operations, and the drying product is usually ready to use. The goal of this research is to design Paddy Drier with  1000 Kg capacity.  The result of the study showing the design specification of the drier

Energy usage is crucial aspect on agriculture drying process. This step spends about 70% of total energy in post harvest treatment. The design of efficient dryer with renewable energy source is urgently required due to the limitation of fossil fuel energy. This work discusses the performance of air dehumidification using rice husk fuel as heat source for onion, and paddy drying. Unlike conventional dryer, the humidity of air during the drying was dehumidified by adsorbent. Hence, the driving force of drying can be  kept high.  As consequences, the drying time and energy usage can be reduced. Here, the research was conducted in two step: laboratory and pilot scale tests. Results showed that the lowering air humidity with rice husk fuel has improved the energy efficiency. At operational temperature 60oC, the heat efficiency of 75%  was achieved.

Waste Containment Systems

Laboratory study on compacted tropical clay treated with up to 16% rice husk ash (RHA), an agro-industrial waste; to evaluate its hydraulic properties and hence its suitability in waste containment systems was carried out. Soil-RHA mixtures were compacted using standard Proctor, West African Standard and modified Proctor efforts at-2, 0, 2 and 4% of optimum moisture content (OMC). Compacted samples were permeated and the hydraulic behaviour of the material was examined considering the effects of moulding water content, water content relative to optimum, dry density and RHA contents. Results showed decreasing hydraulic conductivity with increasing moulding water content and compactive efforts; it also varied greatly between the dry and wet side of optimum decreasing towards the wet side. Hydraulic conductivity generally decreased with increased dry density for all effort. Hydraulic conductivity increased with rice husk ash treatment at the OMC; but were within recommended values of 1 x 10-7 cm/s for up to 8% rice husk ash treatment irrespective of the compactive effort used. This shows the suitability of the material as a hydraulic barrier in waste containment systems for up to 8% rice husk ash treatment and beneficial reuse of this agro-industrial waste product.

The effect of varying the water content was evaluated in shrinkage, dimensional characteristics and shape of the fruits of coffee during drying. Fruits were used Conilon coffee (Coffea canephora), clone 83 of clonal variety EMCAPA 8141. The fruit was hand-picked and selected only the two stages, cherry and unripe. Different batches of coffee were dried in an oven with forced ventilation with air temperature of approximately 60 ± 3 °C until different levels of water content. Fruit size was determined by varying the volume and shape was examined by sphericity and roundness. The shrinkage of the fruits was determined by the ratio between the volume at each water content and initial volume. It was determined that the projected area, surface area and volume increase with increasing water content for conilon coffee fruit. The shape of the conilon coffee fruits was influenced during the drying process, promoting the decrease of sphericity and roundness values from the reduction of water content. The shrinkage showed a nonlinear behavior with decreasing reducing the water content of the mass of Conilon coffee fruit. The polynomial model represented satisfactorily phenomenon of unit volumetric shrinkage and mass of coffee fruits depending on the water content.

In the present work, experimentation was carried out to study the behavior of exhausted grape marc during the bio-drying process. This process was chosen as an alternative to the typical grape marc thermal drying approach. The aim was to reduce the moisture level thanks to the biological exothermal reactions, and to increase the energy content in the biodried grape marc. The target was the generation of a product interesting for energy options. For the development of the research, a biological pilot reactor and a respirometric apparatus were used. Results demonstrated that bio-drying can decrease the water content saving the original energy content. The final material could be assumed like a solid recovered fuel, class 5:1:1 with a very low potential rate of microbial self-heating.

The drying rate is difficult to control for perilla leaf during the microwave vacuum drying process. Through scientific approaches, this paper made a research on the relationships between drying factors and drying rate, and established a kinetics model on microwave vacuum drying of perilla leaf. The model can predict the water content variations of perilla leaf during microwave vacuum drying, and provides a theory basis for packaging, storage and transportation for perilla leaf production.

The Impact

In this study, a weight-control bender element system has been developed to investigate the impact of matric suction equalization on the measurement of small strain shear modulus (Gmax) during an air-drying process. The setup employed is capable of measuring the shear wave velocity and the corresponding Gmax of the soil sample in either an open system in which the soil sample evaporates freely or in a closed system that allows the process of matric suction equalization. The comparison between measurements of Gmax in the open and closed systems revealed underestimations of Gmax when matric suction equalization was ignored due to the nonuniform distribution of water content across the sample cross-sectional area. This study also investigated the time required for matric suction equalization tse to be established for samples with different sizes. The experimental results indicated two main mechanisms driving the matric suction equalization in a closed system during an air-drying process, namely the hydraulic flow of water and the flow of vapour. While the former played the key role when the micropores were still saturated at the high range of water content, effects of the latter increased and finally dominated when more air invaded the micropores at lower water contents.

Food is an important factor in human life. Indonesia’s main food need is rice. Domestic rice demand continues to increase along with population growth. One of the businesses that can increase the availability of food, especially rice, is to utilize the existing agricultural products even though they have not been utilized economically and intensified the excavation of new food sources. Analog rice is a form of food diversification by utilizing local carbohydrate sources. In this study analog rice made from composite flour mixture of cassava flour, Dioscorea esculenta L, corn enriched with protein Canavalia ensiformis. The purpose of this research is to develop the method of production of analog rice and to test the physicochemical properties including water content, water, protein, and amylose so that it can be applied as food substitute for rice in realizing Indonesia food security program. The largest protein content of 9.156%, the highest water content of 12.431%, water absorption 187%. The amylose content of analog rice amounted to 19.677% included in the low-octane rice.

ABSTRACT Green onion (Allium fistulosum L.) is widely consumed and traded in Brazil as condiment. Because of the high yields in the region of Volta Redonda - RJ and the alternative of drying as a method for preserving the excess production, the objective of this study was to evaluate the drying process of green onions, considering the microbiological quality, and to develop the mathematical modeling of this process. Mathematical models to describe the drying of agricultural products were used to predict the phenomenon. The modified Page equation gave the best fit to the data. Microbiological quality was evaluated using the analysis of aerobic mesophilic bacteria, molds and yeasts. Dehydration at 60 ºC was the most indicated for green onions, with assured microbiological quality.
