Factors affecting the sugar content of sugar cane in the wet tropics of Queensland: statistical analysis of ccs data at Babinda and Tully
(BSES, 1972) Sturgess, OW; Hogarth, DM; Hurney, AP; Leverington, KC
In the wet tropics, the sugar content of crops is usually below the state's average and is a critical factor in farm economy, particularly during years of low sugar prices. This aspect of sugar production has been the subject of detailed investigation.
Open area and screen resistance measurements on fugal screens
(BSES, 1988) Noble, AG
To determine whether the decrease in fugal capacity was due to the working screen or the wedgewire backing supporting it, a series of measurements were carried out on test specimens cut from the top, middle and bottom of segments of chrome-nickel working screens removed from the two trial machines. One of these had been fitted with a wedgewire backing and the other with conventional woven mesh backing. These measurements, which were carried out by the author at the Chemical Engineering Department of the University of Queensland, included the following: Slot width and open area determination; Photomicrographs of each screen section; Screen resistance of each specimen.
Factory scale trials with laser produced stainless steel screens : Bingera mill 1987 season
(BSES, 1987) Noble, AG
The main objective in the tests carried out at Bingera was to compare the performance of two adjacent, similar, BMA K1000 centrifugals, one of which was fitted with a new set of standard Cr-Ni screens, and the other with a set of laser cut screens manufactured by CSIRO. Initially, the screens in this latter machine comprised six stainless steel segments and two segments produced from commercially pure titanium. However, the two titanium segments tore along the trailing edges several days after installation, and were subsequently replaced with stainless steel segments.
Data-base and data handling programs for Plant Data Record
(BSES, 1981) Dyne, GD
The information contained in the BSES Plant Data Record is stored in computer data-bases for reporting and reference. Data for both the 1979 and 1980 seasons is stored at Bundaberg and reports for each of these years were generated using the data-base software. Listings of the forms required for the collection of new information have also been produced with this system. The system offers many advantages over the previous manual techniques, including speed and accuracy of report preparation, and the ability to manipulate stored data and report is as required.
Evaluation of laser produced stainless steel screens
(BSES, 1987) Noble, AG
In an effort to develop a more acceptable alternative to the chrome-nickel screens presently in use, BSES approached the CSIRO Division of Manufacturing Technology in Sydney towards the end of 1985 to ascertain the feasibility of manufacturing fugal screens from stainless steel by some method other than the present electrodeposition technique. The eventual outcome of these preliminary discussions was that two screens (one slotted, and the other with round holes) were produced from 300 um thick stainless steel 302 sheeting using a method involving laser technology. The specifications for these two screens, together with that for the chrome-nickel screen currently used in the industry, are given in this report.
Evaluation of high open area screens
(BSES, 1987) BSES Staff
Following the offer from ANI-Sargeants of several sets of high open area screens for testing, trials were arranged at Fairymead and Millaquin Mills, as it has been the contention that higher open areas would allow higher fugalling rates for the same purging efficiency and purity rise.
A condensed report on cane deterioration trials : Fairymead, 1967 season
(BSES, 1968) Messrs, PG; Egan, BT; Kirby, LK
Following Discussion between the Australian Producers' Association and the Director of the Bureau of Sugar Experiment Stations it was decided to carry out a series of cane deterioration trials in the South Queensland district during the 1967 season. As management of Fairymead Mill offered to supply and harvest cane for these tests from their plantation, and to make available laboratory facilities for this work, it was decided to carry out the work at Fairymead.
Fibre characteristics of cane - results of measurements carried out at Bundaberg during 1986 season
(BSES, 1986) Noble, AG
During September, 1986 the decision was made to test for extreme fibre characteristics all cane varieties which are prospective Q canes, in the last season before release. The purpose of these tests was to obtain some indication which varieties were likely to cause handling problems during the milling process.
Fibre characteristics of cane - results of measurements carried out at Bundaberg during 1987 season
(BSES, 1987) Noble, AG
During September, 1987 a total of twenty-three samples of cane were tested for extreme fibre characteristics at BSES in Bundaberg. The main purpose of this testing program, which was introduced during 1986 season, is to screen all prospective Q canes prior to their release to obtain some indication which varieties are likely to cause handling problems during the milling process.
An investigation of factors affecting ash in first expressed juice in the Rocky Point mill area
(BSES, 1981) Kingston, G
Because of a deep concern at the level of ash in Rocky Point sugars and the lack of information on inorganic composition of juices entering the factory the management of W H Heck and Sons requested BSES to undertake an investigation in 1979 which might assist in identification of factors which contribute to the ash problem at Rocky Point. Accordingly a project was planned to allow identification of the major factors contributing to the ash loading in first expressed juice and to determine whether the ash levels in juice could be related to yield parameters affecting cane growers in the mill area.
