Abstract
This study was conducted to design, construct and test the performance of ash dispenser in terms of dispensing capacity and efficiency.
Design of the device was prepared at the Drawing Room of the Department of Agricultural Engineering. Construction and performance testing were undertaken at the Farm Shop of the Agricultural Engineering Department November 5, 2005 to December 12, 2005 and February 20, 2006, respectively.
The principal parts of the device are the following; hopper, uppertube assembly, ash dispenser, lowertube assembly, splash assembly, breather, sight glass, pushing rod.
The cost of the machine was P2,712.85.
The treatments were as follows:
T1 – 100% ash
T2 – 95% ash + 5% sand
T3 – 90% ash + 10% sand
T4 – 85% ash + 15% sand
T5 – 80% ash + 20% sand
The Completely Randomized Design (CRD) with five treatments and three replication was used.
Analysis of variance was used to determine the significant difference between
treatments. Duncan Multiple Range Test was used for further test of significance.
Based on the result of the study, T5 (80% ash and 20% sand) obtained the highest dispensing efficiency with 94% and T1 (100% ash), the lowest with 60%.
Analysis of Variance showed a highly significant difference between treatments, in terms of dispensing efficiency. Among the treatments, T5, T4 and T3 were comparable. Likewise, T3, T2 were also comparable to each other. However, T1 (100% ash) was highly significantly different as compared to other treatments. This could be attributed to the fact that T1 was a pure ash and had the lightest in terms of weight. Thus resulting to had the most amount of absorbent material left inside the device considering the effect of law of gravity.
Furthermore, the study claimed that T5 (80% ash and 20% sand) registered the highest actual capacity with 0.47kg. In the other hand, T1 (100% ash) was the lowest with 0.30kg.
Analysis of variance revealed highly significantly difference. This finding showed that mixing ash with sand resulted to a better downward flow of the absorbent. It was concluded therefore that the greater the amount of sand the better the efficiency and capacity of the device.
