The IGPC's Engineering Department designed basic technological and machine projects for a granulated zeolite production plant, on the basis of which a pilot plant with an initial capacity of 5,000 t/y was constructed in 1984, within Birac - Zvornik production complex. The technology in these projects was developed in the laboratories of the IGPC.Several goals were realized by designing a granulated zeolite production plant. This technology is one of the newest state of the art high tech technologies. The product meets all quality demands, as well as environmental regulations, by which granulated zeolite production for various uses was developed. The granulated zeolite production process is fully automatized, and the product has uniform quality. There is no waste material in granulated zeolite production, because all products with unsatisfactory quality are returned to the process. The production process can be controlled manually, which is necessary during start - up, and repairs.

Abstract The industry of processed dairy and fruit sweets is listed in the agroindustry as one of the most representative at the economic level preceding poultry and oil palm production. In addition, the requirements of safety and product quality that are indispensable, it also requires committed and specialized labor generating a social impact in terms of employability and competitiveness of the companies that make up the production chain. The production process is carried out in an artisanal way, therefore, one of the problems faced by this industry is the absence of technology and / or automation that allows them to improve process times and, consequently, productivity. However, this can be solved with the incorporation of systems that optimize the acquisition and control of the process variables of cooking and dosing of the sweet, reducing the costs due to waste and poor handling of its ingredients, as well as reaching higher production levels with quality and products that meet the standards imposed by globalized markets. This article shows the development, implementation and start-up of a pilot plant for the cooking and dosing of the sweet, taking into account that the capacity of the hopper is 70 liters. The results show a considerable improvement in the quality and process standards, as well as establishing criteria to optimize other variables that appear in the development.

Abstract Guayule rubber has been used both in the resinous and deresinated form for more than sixty years during periods of either scarcity or high prices of hevea rubber. During this time little or no efforts have been made to standardize the individual processes to a point where the products had specifications similar to the “Technically Specified Rubbers”. This lack of specifications consequently left users of the guayule rubbers with various opinions of the capabilities of this type of natural rubber in their commercial products. It was generally believed that the rubber was only good for low-grade products or where guayule was only used as a tackifier for other rubbers. Recent interest in the utilization of arid regions and the increasing need for less dependence on foreign sources has led the Mexican government to develop a modern guayule product. It was the purpose of this study to evaluate Mexican guayule rubber in cooperation with CIQA in an effort to determine processing and vulcanization characteristics of the products prepared in their pilot plant in Saltillo, Mexico.
