Energy Consumption of a Breeder Gin Stand by Sample Size and Saw

Highlights Study included six sample sizes of seed cotton ranging from 0.1 to 1.6 kg. Linear model was a good fit for full range of sample sizes tested. The model showed that energy data is comparable across range of sample sizes tested. More than ginning energy, the ginning time was sensitive to small sample sizes. Abstract. Ginning seed cotton on a 10-saw breeder gin stand with 10-in. saws is often a batch process and there are variables which may affect energy consumption. This study focused on differences in energy consumption of a 10-saw breeder gin stand across five sample sizes of seed cotton ranging from 0.1 to 1.6 kg while also including two sets of saws. An independent t-test found no significant difference in the energy data for similar tests performed on different days, i.e., the conditions under which the test ran did not significantly affect the results. A linear model found evidence that the saw variable and sample size were important to the model. Differences in the model between the saw sets may be due to the surface finish of the saw blade; the geometry of the saw blade may also be important. These results will help to develop guidelines for comparing data across different sample sizes and saw conditions on breeder gin stands.
