Perdas econômicas vinculadas às etapas de beneficiamento de milho e trigo, em unidade cooperativa do norte do Paraná.

Abstract

Resumo -A produção nacional de grãos cresce ano após ano, entretanto o sistema agrícola não se desenvolve como um todo. Áreas como o beneficiamento de grãos ainda apresentam elevadas perdas de ordem quantitativa e qualitativa, o que culmina em perdas econômicas de grande porte nas unidades beneficiadoras de grãos. O presente estudo buscou evidenciar as perdas econômicas oriundas do beneficiamento de grãos das culturas de milho safrinha e trigo no ano agrícola de 2006, em uma unidade beneficiadora/armazenadora de grãos, localizada na região norte do estado do Paraná. Para tal, o processo de beneficiamento, em caráter comercial, foi acompanhado com vistas ao levantamento da quebra técnica ocasionada por grãos danificados e pela secagem excessiva, nas diversas etapas do beneficiamento (recebimento, pós-secagem e expedição). Os dados percentuais foram extrapolados para a capacidade estática total da unidade observada, sendo convertidos a valores monetários, considerando o valor comercial presente dos produtos. Pode-se observar que as etapas de beneficiamento da unidade contribuíram para o aumento de danos em grãos de milho e trigo, elevando a porcentagem de impureza, quebrados e triguilho da fase de recebimento até a fase de expedição. Os resultados econômicos apresentaram uma perda associada de R$ 220.083,00 para a secagem excessiva e de R$ 52.800,00 por danos aos produtos quando da analise da capacidade total da unidade beneficiadora/armazenadora.Palavras-chave -Pós-colheita.

Steps such as the processing of grains still contain high losses of quantitative and qualitative, which culminates in large economic losses in grain processing units. The present study sought to highlight the economic losses arising from the processing of grain crops of winter corn and wheat in crop year 2006 in a unit processing/grain store, located in the northern region of Paraná State. To this end, the improvement process in a commercial level was accompanied with a view to raising the technical breakdown caused by grain damaged by excessive drying and, in various stages of processing (receiving, shipment and post-drying). The percentage data were extrapolated to the total static capacity of the unit recorded and converted to monetary values, considering the commercial value of this product. It can be seen that the steps of processing unit contributed to the increase of damage in corn and wheat, raising the percentage of impurity, and broken wheat middling phase until the phase of receiving shipment. The economic results showed an associated loss of R$ 220,083.00 to excessive drying and R$ 52,800.00 for damage to products upon analysis of the full drive capacity processing/store.

Physic-Chemical Quality of Second Crop Corn as a Function of Time Between Harvest and Drying

“…However, even with increasing productivity rates and a heated market, a number of drawbacks are present in the production chain. The post-harvest area and its lag in the storage sector can be seen as one of the main problems once the implications promoted by this affect cost / benefit balance (Kolling et al, 2012;Kussano & Batalha, 2012). …”

Economic viability of implementing a diesel generator group in a grain storage facility located in the City of Cascavel, State of Paran, Brazil

“…In the last survey on grain production, CONAB (CompanhiaNacional de Abastecimento / National Food Supply Company) verified that the 2012/2013 crop reached 187.09 million tons, 12.6% more than the 2011/2012 crop (CONAB, 2013). The harvest flow system involves the process of storing agricultural products, an extremely important step for maintaining grain quality, since it is useless to produce well if this production could be compromised by an inadequate storage process (Alencar et al, 2009;Kolling et al, 2012).…”

Wheat Variety Response to Seed Cleaning and Treatment after Fusarium Head Blight Infection

“…However, the effects of seed treatment on grain yield are inconsistent, with previous research showing no yield gain (Kashyap et al, 1994) or a positive association with wheat yield (Lollato et al, 2018). Due to the inconsistent yield response and an increased cost of production, seed treatments have not been widely adopted among wheat producers (Kolling et al, 2012).…”
