The development and evaluation of an on-line sugar purity meter for use in a low grade continuous centrifugal

Moodley, Manogran January 2001 (has links)
Submitted in partial fulfilment of the academic requirements for the Degree of Master's Degree in Technology: Chemical Engineering, ML Sultan Technikon, 2001. / There are two process operations in the sugar factory that directly affect the recovery of sugar from evaporated syrup, namely crystallisation (boiling) and centrifugal operation. Successful automation of the vacuum pans (boiling) has been implemented using brix (total dissolved solids) control, but to date on-line measurement of continuous centrifugal performance has not been successfully accomplished in South Africa. The purpose of this investigation was to continue the preliminary work performed by Tongaat Hulett Sugar in developing a purity meter for the measurement of sugar purity (sucrose content) in a continuous centrifugal. This instrument would provide the centrifugal operator with a reliable tool to perform on-line measurement of sugar purity and would also facilitate the automation of the centrifugal / M

Growth of the cotton industry and Scottish economic development, 1780-1835

Robertson, Alexander James January 1965 (has links)
This study is intended, first of all, to be an examination of the growth of the cotton industry in Scotland from 1760 to 1835. During this period, it became the largest and most important sector of the Scottish industrial economy, producing over 70% of the country's exports by value. There is, however, a subsidiary problem, that of placing the industry's growth within the general context of Scottish economic development in the eighteenth and nineteenth centuries. The choice of terminal dates was to some extent dictated by the availability of material. The Old Statistical Account of Scotland, probably the most important single source of information on the establishment of the cotton industry, was compiled in the last two decades of the eighteenth century. The early 1830's saw the compilation of the New Statistical Account and the publication of the findings of the Factories Inquiry Commission and the Select Committee on Manufactures, Commerce and Shipping, all important sources for the industry's later development. Separate Scottish Customs records ceased to be kept in 1827, after which date no reliable guide to the importation of raw cotton into Scotland is available. But the date I780 does mark approximately the industry's foundation in Scotland, while 1835 marks the end of the main period of its expansion. The problem of the industry's foundations and growth was dealt with by adopting a topical approach. The first topic to be discussed in this connection was that of the physical growth of the industry from 1780 to 1835, which involved an examination of the expansion of raw cotton consumption and of the number and size of the units of production. At the same time, the industry's location was considered. The next step was to consider the capitalization of the industry, the factors which stimulated the transference of capital and entrepreneurial ability from other sectors of the economy, and the response of the industry to consumer demand by specialization in certain types of product. These were considered to be the factors which made the industry's expansion possible. The most important problems involving labour in the new industry - labour recruitment, wages and conditions of work and the formation of labour organizations - were also considered. In dealing with the subsidiary problem, a narrative approach was adopted. The first chapter, therefore, is simply a description of the developments within the Scottish economy which preceded the establishment of the cotton industry. Thus, the economic conditions out of which the industry grew and in which the capital, production skills and other requirements for its growth were acquired could be set out. The last chapter is intended to show the effects of the cotton Industry's development on other sectors of the Scottish economy. The Scottish cotton industry developed out of the economic crisis which followed the loss of the American colonies in 1783. Its expansion after that date was rapid, though subject to considerable fluctuations due to uncertain market conditions arid a rather narrow specialization in the type of fabrics produced. The industry's expansion was undertaken by means of the adoption of new production-techniques and new forms of organization, which marked a change-over from the system of manual production in small-scale units to mechanized production in large-scale factory units. These came to be centred in the south-west of Scotland, around Glasgow, because of the advantages which that area enjoyed over others in respect of access to markets and raw materials and because it possessed resources of highly-skilled labour which other areas lacked. Capital and entrepreneurial skills acquired in the pre-American Revolutionary period, mainly in other textile industries, were utilized to build up the new industry, which also appears to have based its initial expansion on the exploitation of' markets previously served by the linen industry. These proved to be inadequate, however, and new products had to be developed to ensure continued expansion while avoiding direct competition with Manchester. The industry relied heavily on supplies of immigrant labour to man its factories. The working conditions within the factories varied from place to place according to the attitudes of individual managers, and wages, too, varied from one factory to the next, and even from man to man in any one mill. In general, factory wages fluctuated with the trade cycle, while wages in the remaining domestic section of the industry, handloom weaving, seem to have declined steadily at least from 1806. The concentration of the labour force in large units offset the advantages which the employers had always enjoyed in disputes with labour, and permitted the foundation of strong and effective militant labour organizations. The development of the cotton industry led to the expansion of other industries in Scotland, notably the secondary textile industries like bleaching and dyeing. Its adoption of mechanized techniques of production promoted the growth of the engineering industries in the Clyde Valley, and the increased demand for chemicals for cloth-finishing which resulted from its expansion led to considerable expansion of the chemical industry. In these ways, the cotton industry laid the basis of the Scottish economy of the twentieth century. / Arts, Faculty of / History, Department of / Graduate

Ventilation System Simulation Model at a Mine

Artica, I., Quispe, G., Raymundo-Ibañeez, C. 25 November 2019 (has links)
This research project modeled and simulated a ventilation system at a Mining Concession, obtaining real-time information regarding the fans used to ventilate the mine. The simulation was developed using the VENTSIM 5 software, which also helped define the number of fans and the operating parameters required, field information, mine dimensions, the mining method, production, geothermal gradient, gas emission, air stream, and air pressure. In addition, the results from software operation revealed the need to open chimneys and use fans. Furthermore, the results also suggest that a specialist dedicated to ventilation and fan maintenance must be hired to formalize mining operations as per the Occupational Safety and Health Mining Regulations from Executive Action No. 024-2016-EM as this Mining Concession is currently operating without license.

Applying Case-Based Reasoning to Assembly Part Design

Chang, Guanghsu, Su, Cheng Chung, Priest, John W. 01 December 2006 (has links)
Over 70% of final product costs are determined by initial product design. Hence, to depict a capable and reliable part design is important during the part conceptual design phase. Case-Based Reasoning (CBR), based on analogical reasoning, is a problem solving methodology. This paper proposes the CBR architecture applied to assembly part design for effectively managing previous design experience and evaluating assemblability and manufacturability of assembly part design. The results can provide a useful reference for novices to reuse and revise previous experience and experienced designers to impart their expertise through CBR methodology.

A Study of the Manufacture of Frozen Desserts from Dry Ingredients

Dajani, Shihadeh H. 01 May 1963 (has links)
In many parts of the world where milk production is limited, there is an opportunity to process dairy foods from imported concentrated milk products. Dry ingredients can be shipped conveniently and some can be stored several months generally without deterioration. In these milk deficient areas, dried ingredients of good quality and with proper processing should increase the use and consumption of dairy products. A large supply of high quality milk by-products which are fit for human consumption are available in the world today. Many investigators and manufacturers have used dried milk by-products as a source of milk solids in frozen desserts with favorable results. It is possible to process ice cream mix using dry ingredients only. Such ingredients include nonfat dry milk, dried buttermilk, dried whey or dried whole milk. Butter oil or vegetable oils may be used as the source of fat. Dried dairy ingredients can be used to make a good quality ice cream which has a relatively low cost and is convenient to process. In countries where fluid milk is scarce the use of dried products in frozen desserts allows more fresh milk to be marketed as such. In this study it is planned to investigate the sources, uses in processing, and quality results of dry ingredients in ice cream.

A Geographical Analysis of the Emergence and Subsequent Disappearance of the Cotton Industry in the Virgin River Basin (1856-1910)

Hanson, Brooks Kent 01 January 1967 (has links) (PDF)
At one time the cotton industry in Utah was a flourishing activity. Many pioneer farmers were engaged in the growing of this staple for the purpose of providing much needed cotton for the Territory of Utah before the days of railroads and highways. After the favorable climatic conditions for agriculture in Utah's Dixie were discovered, leaders of the Latter-day Saint Church made plans for the growing of many fruits and vegetables of the temperate zone. Of these, cotton received by far the most attention, as a domestic source of this raw material was at one time vital to the well being of the Territory of Utah. Hundreds of pioneer families were sent to this southerly location below the rim of the Great Basin to swell Utah's production of this commodity.
