1a.Objectives (from AD-416):
1) Identifying the cultivar differences which affect ginning and textile performance and then identify parameters which are measurable in real-time to control for these differences.
2) Monitor energy use by several gins during the course of the ginning season to identify technologies and management strategies that can reduce energy requirements per bale.
3) Examine ways to adjust or retrofit normal seed cotton cleaning equipment so that it is more efficient in removing sheet-plastic materials, such as used in shopping bags and John Deere module covers.
1b.Approach (from AD-416):
A wide variety of cultivars will be collected and their fiber quality properties measured. The data will be analyzed to determine variation due to cultivar and growing conditions for different ginning machines (not all conditions for all varieties will be possible - a subgroup of combinations will be used). Data will also be collected with alternative machine operating parameters to identify optimum settings for different cultivars and/or growth conditions. The work will proceed under controlled conditions using the ginning equipment at the Cotton Ginning Research Unit and will be coordinated with researchers in the Crop Genetics Unit at Stoneville, MS.
Electricity use was monitored at several gins from 2010-2012. Additional process parameters, such as temperature, humidity, feed control speeds, and static pressures across fans were also monitored. Fuel use was monitored at two gins in 2011 and 2012. A comprehensive analysis of the fuel use data is planned for 2013. Additional data will be collected during the 2013 ginning season. Additional focus will also be placed on explaining the relationship between gin stand power consumption, agitator power consumption, ginning rate, and quality parameters.
To better understand how ginning equipment handles pieces of sheet plastic 5 types of plastic commonly found in U.S. seed cotton fields or used in handling seed cotton will be cut into several different sized pieces and added to seed cotton. This mixture will be processed in a research ginning system with normal ginning equipment sequence. Adjustments to the standard ginning equipment such as shaft speeds and grid bar-cylinder spacing will be varied to determine if improved removal of plastic material can be achieved. Alternative cylinder and grid bar designs will be considered.
Project was begun in January. Additional studies of the ginning response related to cultivars have been completed. Data collected in the past regarding energy use in gins have been evaluated. Plans and equipment for further data collection in 2013 have been assembled. Additional cotton with added plastic material have been processed in the microgin. The resulting data are being evaluated.
