“…Before the grains are stored in the silos, the product goes through the processing phase, which consists in the removal of excess moisture and impurities, followed by the grains being weighed and unloaded. For these steps, the storage units (Figure 2A) have cleaning machines and grain dryers (Gresele, 2020;Bellochio & Coradi, 2022). The stages that the product goes through before being stored can be classified as receiving, cleaning, and drying.…”

With the expansion of global grain production, in which Brazil ranks 4th with 7.8%, and, in light of the estimated production for the 2022/2023 harvest of 309.9 million tons, there is a deficit in storage capacity, currently representing 60.9% of production. Given the importance and expectation of expanding, it is necessary to prevent illnesses and accidents linked to this process. This work aims to develop an occupational hazards management model during the grain storage and drying processes, to determine the hazards that workers are exposed in their activities. The methodology was applied in western Paraná, Brazil, in a grain drying and storage unit during the inter-harvest and harvest periods to analyze, identify, evaluate, prioritize, and develop an action plan for the hazards. Among the hazards identified in the literature and at the site, exposure to heat and noise was evaluated, generating a score that represents the hazard situation in the environment. Of the 104 possible points in the evaluation, occupational exposure to heat obtained the lowest score of 70 (regular level), compared to noise with a score of 90 (normal level). For solving identified non-conformities, it can be highlight the replacement of thermal protection gloves and installation of a on-site temperature and humidity meter. With the methodology, it is possible to evaluate hazards and propose mechanisms that lead to their resolution, prioritizing the most critical levels according to the generated score.

“…There are few studies related to occupational hazards developed in post-harvest activities in pre-processing and grain storage units. Thus, such studies are recent in identifying the causes of occupational incidents in this line of work (Geng & Dee, 2018;Kakhki et al, 2019;Chen et al, 2020;Bellochio & Coradi, 2022).…”

“…A popular method of grain storage is outdoor, with a full filling of the barn space; grain cargo transportation is conducted by belt conveyors 150-200 m long, which are used for automatic loading and unloading. Bellochio and Coradi report that for a long time, grain raw materials are subject to storage in specially equipped granaries and elevators and compliance with grain quality indicators at the level of all producers: farmers, agricultural firms, united associations, industrial grain combines [20]. Kholy and Kamel describe the condition of grain warehouses in conformity with their purpose, dividing them into purchasing, transhipment, production, and basic [21].…”

The purpose of the study is to examine the efficiency of transportation and productivity of the process of moving grain cargoes, with the improvement of the design and technological scheme of the belt conveyor when clogged with grain dust. Using the methods of analysis, synthesis, and comparison, the basic concepts and applied studies of belt conveyor performance by operating parameters are investigated to justify the optimal design and technological actions that reduce energy intensity and substantiate the economic efficiency of agricultural production. The results indicate that the study allowed determining the dynamic loads that lead to failures of conveyor elements, dust clogging of roller supports, and belt ruptures. The study emphasizes the issues with dynamic loads that result in conveyor element failures, clogged roller supports from dust, and ruptured belts. A review and analysis of studies on existing technologies showed the impact of design features on the productivity and quality of grain transportation. Modification of the rollers on the ascending branch of the working body of the belt reduces grain losses on both sides when slipping on the drive drum.

Objetivo: Caracterizar los efectos del estrés laboral en las funciones cognitivas de los trabajadores de las empresas hoteleras de la ciudad de Sincelejo, Sucre. Metodología: De los ochenta y nueve (89) hoteles registrados en la Cámara de Comercio de Sincelejo, se seleccionó una muestra de veinte (20); así mismo, los sujetos de estudio designados como colaboradores a encuestar fueron un total de cincuenta y tres (53) miembros del personal de dichos hoteles con más de 5 años de experiencia en el área. Una vez seleccionada la muestra, se aplicó la encuesta preparada para la presente investigación, con un total de 18 preguntas. El cuestionario se construyó empleando la escala tipo Likert, mediante cinco (5) alternativas de respuesta con su ponderación correspondiente: Siempre (S), Casi Siempre (CS), A Veces (AV), Casi Nunca (CN) y Nunca (N). Resultados: Los resultados evidencian que el estrés laboral se encuentra Presente en las funciones cognitivas de Concentración y atención, Memoria, Errores, Reacciones inmediatas y Lógica y organización, en tanto que se encuentra Moderadamente presente en la función cognitiva Evaluación actual y proyecto a futuro. Conclusiones: Se pudo concluir que la presencia del estrés laboral en las funciones cognitivas pueden tener efectos negativos sobre la calidad de vida laboral de los trabajadores y a su vez en su desempeño dentro de la organización.
