The immunocorrective properties of the basidial fungus Phallus impudicus were evaluated in order to further use the drug in various dosage forms for batch control according to the indicator "Biological activity" in the conditions of control services laboratories.

Planejamento e controle da produção em uma empresa alimentícia de pequeno porte

O Planejamento e Controle da Produção (PCP) é fundamental para que uma empresa defina suas metas e estratégias no mercado a fim de criar um plano de gestão para seu bom desempenho. Dessa forma, o objetivo do presente estudo é realizar verificações associadas à gestão de demanda, estoque e capacidade e propor a implantação de um sistema de PCP em uma empresa de pequeno porte do ramo alimentício, situada no Espírito Santo, Brasil. O estudo usou como referências metodologias de implantação de PCP e análise de processos consolidadas na literatura. Para a execução do trabalho foram realizadas observações diretas do processo produtivo e entrevistas in loco. Os resultados mostram que a empresa estudada não realiza procedimentos formais de gestão de demanda e estoque, mensuração da capacidade e também rotinas bem definidas, o que resulta em problemas associados ao processo produtivo. Com isso, foi possível seguir os passos de implantação e fornecer as estratégias iniciais para que o PCP possa ser implantado, por meio do desenvolvimento de planilhas eletrônicas associadas a filosofia Kanban e ao Period Batch Control, sem que seja necessária a compra de um software de gestão. Adicionalmente, a investigação, análise, sugestões e simplificações dos processos produtivos realizados no presente trabalho são fontes de informação para pesquisas futuras em situações similares a da empresa estudada.

PLC Batch Process Control Design and Implementation Fundamentals

Batch process control is typically used for repeated chemical reaction tasks. It starts with a measured liquid material filling operations followed by a controlled reaction leading to the discharge or transport of processed quantities of material. The input materials is contained in vessel reactor and subjected to a sequence of processing activities over a recipe predefined duration of time. Batch systems are designed to measure, process, and discharge a varying volume of liquid from drums, tanks, reactors, or other large storage vessel using a programmable logic controller (PLC). These systems are common in pharmaceutical, chemical packaging, Beverage processing, personal care product, biotech manufacturing, dairy processing, soap manufacturing, and food processing industries. This paper briefly discusses the fundamental techniques used in specifying, designing, and implementing a PLC batch process control [1, 2]. A simplified batch process is used to illustrate key issues in designing and implementing such systems. In addition to the structured PLC ladder design; more focus is given to safety requirements, redundancy, interlocking, input data validation, and safe operation. The Allen Bradley (AB) SLC 500 PLC along with the LogixPro simulator are used to illustrate the concepts discussed in this paper. Two pumps are used to bring in material during the tank filling and a third pump is used to drain processed product. The three pumps are equipped with flow meters providing pulses proportional to the actual flow rate through the individual pipes. The tank material is heated to a predefined temperature duration followed by mixing for a set time before discharge. Batch control systems provides automated process controls, typically and universally using PLC’s networked to HMI’s and other data storage, analysis, and assessment computers. The overall system perform several tasks including recipe development and download, production scheduling, batch management and execution, equipment performance monitoring, inventory, production history and tracking functionalities. Flexible batch control systems are designed to accommodate smaller batches of products with greater requirements / recipes variation, efficiently and quickly. In addition to providing process consistency, continuous batch process control quality improvements are attained through the automatic collection and analysis of real-time reliable and accurate event performance data [3, 4].

Fuzzy batch controller for granular materials

The paper focuses on batch control of granular materials in production of building materials from fluorine anhydrite. Batching equipment is intended for smooth operation and timely feeding of supply hoppers at a required level. Level sensors and a controller of an asynchronous screw drive motor are used to control filling of the hopper with industrial anhydrite binders. The controller generates a required frequency and ensures required productivity of a feed conveyor. Mamdani-type fuzzy inference is proposed for controlling the speed of the screw that feeds mixture components. As related to production of building materials based on fluoride anhydrite, this method is used for the first time. A fuzzy controller is proven to be effective in controlling the filling level of the supply hopper. In addition, the authors determined optimal parameters of the batching process to ensure smooth operation and production of fluorine anhydrite materials of specified properties that can compete with gypsum-based products.
