Since 2003, Suiker Unie has used an off-line image analysis system (IAS) to measure the size distribution of crystals in industrial massecuites. This paper describes the technical set-up, the methods of sampling and sample preparation, and of particle sizing and classification. Based on the experiences of Suiker Unie a couple of improvements were developed that have been realized when updating the system in 2015/16. Analyzing final Aproduct (Asugar) with a crystal size of approximately 600µm was not possible with the original system. When updating the system the opportunity was taken to extend the measuring range to include Asugar. The original light-microscope and automated XYstage were extended with new components: an XYstage controller, a high resolution camera and customized image analysis software, providing new methods of image acquisition and processing. The new hardware and software configuration now allows measurements in the crystal size range of 10µm to 2000µm. The sample preparation procedure was modified to avoid false grain formation especially in suspensions of low purity. Samples are now directly dispersed in a sucrose-fructose solution. The updated system and procedure show less variance in mean aperture (MA) and coefficient of variation (CV) compared to the formerly used method. Both seed crystals and the final Asugar can now be analyzed, thus covering the complete sugar crystallization process.

A new fast measuring method for process optimization of sucrose crystallization using image analysis based on high quality images and algorithms is introduced. With the mobile, non-invasive at-line system all steps of the sucrose crystallization can be measured to determine the crystal size distribution. The image analysis system is easy to operate and is as well an efficient laboratory solution with user-friendly and customized software. In comparison to sieve analysis, image analyses performed with the ParticleTech Solution have been proven to be reliable.

Biostereology in China is very active. Here is a brief summary: Organization: The organization of biostereology in China was founded in Nov. 1988. Its name is Chinese Society of Biomedical Stereology (CSBS), and is affiliated to the Chinese Society for Stereology (CSS). The first joint president of CSS/BMC was Prof. Peixuan Tang, the second and now the third, is Prof. Dewen Wang. There are 556 registered members. Academic Congresses: Sessions of the National Biostereological Congress were convened in 1990, 1992, 1996 and 2000. Publications: Four works were written and published in China. One is "Quantitative Histology" (Luji Shi, 1964), another is "Stereological Morphometry For Cell Morphology" (Fusheng Zheng, 1990), the third one is "Practical Biostereological Techniques" (Hong Shen and Yingzhong Shen, 1991) and the fourth one is "Quantitative Cytology and Cytochemistry Techniques" (Genxing Xu, 1994). A Chinese Journal of Stereology and Image Analysis has been published since 1996. Courses: More than ten national training courses on biostereology were held. In some medical universities or colleges, a biostereology course has been set up. Theoretical studies: Some new concepts, parameters and methods for stereology and morphometry were put forward, such as: regular form factor, volume concavity, surface concavity, area concavity, boundary concavity, curve profile area density, positive university for immunohistochemistry stain etc. Application: Stereological methods have been widely applied in biomedical studies. The applied field covered most of the morphological domain of biology. The main applications of biostereology are quantitative pathological diagnosis and prognosis of tumor cells and histostructures. Most studies utilize classical stereological methods. New stereological methods should be popularized and applied in the future. Image Analysis System: Image analysis systems are widely used in biostereological studies. About ten kinds of image analysis systems have been manufactured in China. The most popular is HPIAS, which is made by Huahai Electronic CO.LTD.

Reclamation System

Much progress has been made in recent years towards the development of closed-loop foundry sand reclamation systems. However, virtually all work to date has determined the effectiveness of these systems to remove surface clay and metal oxide scales by a qualitative inspection of a representative sampling of sand particles. In this investigation, particles from a series of foundry sands were sized and chemically classified by a Lemont image analysis system (which was interfaced with an SEM and an X-ray energy dispersive spectrometer) in order to statistically document the effectiveness of a reclamation system developed by The Pangborn Company - a subsidiary of SOHIO.The following samples were submitted: unreclaimed sand; calcined sand; calcined & mechanically scrubbed sand and unused sand. Prior to analysis, each sample was sprinkled onto a carbon mount and coated with an evaporated film of carbon. A backscattered electron photomicrograph of a field of scale-covered particles is shown in Figure 1. Due to a large atomic number difference between sand particles and the carbon mount, the backscattered electron signal was used for image analysis since it had a uniform contrast over the shape of each particle.

Abstract The computerized image analysis system has been successfully used for determination and statistical processing of the following geometric characteristics of activated sludge flocs: longest dimension, breadth, equivalent diameter, cross-sectional area, perimeter, elongation, and circularity. These parameters could be effectively and precisely determined by the system applied. In addition, the studied method, as compared to direct microscope observation and photography floc-sizing methods, was found to be more accurate, less time-consuming, and less dependent on the investigators.
