Development of Manually Operated Citrus Fruit Harvester

Technology of manually operated sampler pipets.

We have evaluated the performance of manually operated sampler pipets. Twenty-four instruments of various construction, manufacture, and delivery volume were evaluated. Pipet-delivered water and serum were repeatedly weighed under controlled environmental conditions, and precision and accuracy assessed. The pipets often failed to meet the manufacturer’s stated tolerance limits. Consumers should...

Ergonomics evaluation of a manually operated cassava chipping machine.

A manually operated machine for chipping cassava was evaluated. Six farmers took part in the study, with physiological, postural, and subjective measurements being taken. Using the machine resulted in drudgery and postural discomfort. Following an iterative design process and using appropriate anthropometric measurements, an improved, adjustable prototype was developed. This was tested with the...

Methods for Reducing Acidity in Citrus Fruit

PRO-GEN® (arsanilic acid or P-G) has been shown to reduce acidity of Florida grapefruit as effectively as lead arsenate. A series of experiments in the 1987-88 citrus fruit sea son reconfirmed that P-G was effective for this use with con centrations of 600-1500 ppm. P-G is water soluble. However, deliberate attempts to wash it off immediately following spray application reduced its effectivenes...
