Item Desenvolvimento de um aplicativo na Power Plataform para gestão de qualidade assegurada em uma indústria alimentícia: Matriz QA em ação(2023-09-15) Silva, Rafael Aldreem Alves da; Ghislandi, Marcos Gomes; http://lattes.cnpq.br/3409757365313853; http://lattes.cnpq.br/1915012203419619This study highlights the development and implementation of an application on the Power Platform, using SharePoint as a database, aimed at quality management in the food industry, emphasizing the QA Matrix. Considering the complexity and regulations of the food sector, ensuring quality is essential. The application developed centralizes information, optimizes the management of QA's history, reduces the dispersion of documents and strengthens the management and control of QA's. The QA Matrix is applied in a structured manner, facilitating the identification, prioritization, and mitigation of risks. The research highlights the effectiveness of the integration between Power Platform and SharePoint, bringing benefits such as the consolidation of databases and files, refined control over trends and errors in preparation, and an improved interface compared to previous methodologies. The transition from multiple files to a single application, combined with an intuitive interface and preventive adjustments, results in time savings and greater precision in the construction of the QA Matrix. The proactive approach adopted reinforces the commitment to excellence in quality in the food industry.Item Aplicação de nanomateriais advindos de biomassa para tratamento de águas residuárias da indústria têxtil(2019-01-25) Nascimento, Rizia Keila do; Araújo, Ana Cláudia Vaz de; http://lattes.cnpq.br/6861890992609511; http://lattes.cnpq.br/8972131109377770The inadequate disposal of industrial effluents has caused serious problems of environmental contamination worldwide. In the textile pole of Pernambuco some cases of river pollution were reported due to the process of dyeing and washing of fabrics. In this work, the feasibility of the use of nanostructured carbonaceous materials (CN) in the adsorption of textile dyes is studied. To obtain the carbonaceous material sugarcane leaves were used, these were washed, dried, crushed and submitted to hydrothermal synthesis. The samples were characterized by X-ray diffractometry (XRD), infrared (IR) spectroscopy, thermogravimetric analysis (TGA) and porosimetric analysis. The synthesized materials were presented as finely divided dark powders. In adsorption analyzes of the indigo carmine and red congo dyes the nanomaterials showed to be promising adsorbents. It was possible to observe a favorable behavior in relation to the adsorption of the dyes in liquid medium. The Langmuir, Freundlich and Redlich- Peterson isotherm models were suitable for the studied materials. The kinetic adsorption analysis suggests a pseudo second order behavior. The adsorptive mechanism of the nanomaterials could be characterized as heterogeneous, with adsorbate / adsorbent interactions of a chemical nature, where adsorption in monolayers is carried out at low concentrations and in multilayers at high concentrations of dye.Item Aplicação das ferramentas da qualidade para a redução das perdas de qualidade numa linha de fabricação de massas(2021-07-15) Cabral, Ariane Nathália de Siqueira Souza; Araújo, Ana Cláudia Vaz de; http://lattes.cnpq.br/6861890992609511; http://lattes.cnpq.br/3246406733304902The competition between companies that work with production in general, forces them to implement improvements in their management and control systems, aiming to reduce losses in production processes. This work was developed in a pasta factory located in the city of Jaboatão dos Guararapes in Pernambuco. The objective of this work was to diagnose and reduce losses in a pasta production line. A survey of losses was made in a production line of Ninho noodles, for a period of six months. The cost of existing losses was estimated, and the responsible sector stipulated a 40% reduction in this cost in the line under study. A study of the operation of this line was carried out. It was found that the main sites for reprocessing were in the press, in the drying tunnel, in the wire mat and in the elevator belt. Thus, from the 5 whys tool, the root causes of the problem were obtained: wire and elevator belt. From the application of the PDCA cycle, the actions were successfully carried out with a reduction of 61% of the non-conformity of the Reprocessing in the Nest-type noodle line. This loss reduction in the four months of the project due to Reprocessing, generated an annual gain of 25.1 ton/year, which means an annual gain of R$ 115,290.00 for the company.Item Produção de nanopartículas magnéticas aplicada ao processo de tratamento de efluentes oriundos das indústrias têxteis(2018-08-27) Damasceno, Bárbara Souza; Araújo, Ana Cláudia Vaz de; http://lattes.cnpq.br/6861890992609511; http://lattes.cnpq.br/6533105269743189Iron oxide magnetic nanoparticles (NPs) were synthetized by chemical coprecipitation method under ultrasound. Synthetized NPs were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, porosimetry and magnetometry. The crystalline phase of the obtained NPs was identified as maghemite and the crystallite average size was estimated by Scherrer equation around 31.5 nm. The FTIR spectra presented distinct absorptions bands at corresponding to intrinsic stretching vibrations of Fe–O bond at the iron oxides. Langmuir and BET surface areas of as-formed samples is 220,15 ± 19,81 m2 g-1 and 127,19 ± 4,94 m2 g-1 respectively. NPs samples present ferromagnetic behavior and saturation magnetization (SM) value of 46 emu g-1. Adsorption performances on synthetized and commercial nanoparticles were investigated and compared. The influences of parameters including pH, dye concentration, and agitation time have been investigated in order to find the optimum adsorption conditions. Parameters as pH 4.0, with 150 min of contact time and dye concentration of 20 mg L-1 were chosen. Adsorption results indicate that the isotherm and kinetics for dye adsorption on NPs obey Freundlich isotherm and pseudo-second-order kinetic, respectively. The maximum dye (20 mg·L-1) removal efficiency to maghemite NPs was found to be 43% and to commercial magnetite NPs was 33%. For the same experimental conditions, maghemite also had better application of the available area for adsorption than the magnetite NPs, presenting values of 8.80 mg g-1 and 6.12 mg g-1, respectively.Item Caracterização de matérias-primas cerâmicas utilizadas na produção de placas de revestimento em indústria do Cabo de Santo Agostinho(2019-12-10) Silva, Renata Arcelino da; Diniz, Verônica Cristhina de Souza; http://lattes.cnpq.br/9239037374332331; http://lattes.cnpq.br/4639841941851252Properties of ceramic products are related to initial characteristics of raw materials, so it is important to study them to obtain a quality product. In this study, aimed to evaluate clay composition and study physical-mechanical behavior of different raw materials used in production of ceramic tiles, allowing their analysis and processing in a simple, controlled and standard. Six unidentified raw materials donated by a ceramic coating industry from Cabo de Santo Agostinho were used. The samples were benefited and characterized per X-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDX) and sedimentary particle size. After, raw materials were uniaxial pressing and subjected to controlled burning at 1000 ºC/ 1h with rate of 5ºC / min. Then, properties were evaluated per of linear shrinkage, water absorption, apparent porosity and flexural strength. The samples presented crystalline phases of kaolinite, quartz, mica and smectite, besides of alkaline oxides. The mechanical properties of samples showed the highest plasticity index (18%) and maximum strength went MP1 and MP6, 18% and 20.45 MPa, respectively. Thus, the raw materials presented physical properties for use in various applications in ceramic tile, such as ceramic.
