Pela inexistência de informações sobre as propriedades mecânicas de sementes de abóbora e pela necessidade de desenvolver equipamentos que possam ser utilizados com mais eficiência para o seu processamento, objetivou-se com este projeto, estudar as propriedades mecânicas de sementes de abóboras comerciais cultivadas no IF Goiano. Foram utilizadas sementes de abóbora (Cucurbita moschata) das cultivares comercial ‘Rajada Seca Melhorada’ e ‘Jacarezinho’ com teor de água variando de 0,670 a 0,094 decimal base seca (b.s.) e 0,923 a 0,033 decimal (b.s.), respectivamente. A determinação da resistência à compressão das sementes foi realizada por meio de ensaios de compressão uniaxial. As sementes foram comprimidas em sua posição natural de repouso, a uma velocidade constante (taxa de aplicação de força) de 0,0001 m s-1. A força média para as deformações na ‘Rajada Seca Melhorada’ foi de 43,90 e 0,56 N e para ‘Jacarezinho’ entre 13,20 e 0,20 N, e os valores do módulo proporcional de deformidade de 8,05 a 23,68 x 107 N m-2 cultivar ‘Rajada Seca Melhorada’ e 2,05 a 21,64 x 107 N m-2 para ‘Jacarezinho’. Conclui-se que a força necessária para deformação das sementes de abóbora decresce com o aumento do teor de água, para a cultivar ‘Rajada Seca Melhorada’ e ‘Jacarezinho’. Há um aumento nos valores do módulo proporcional de deformidade com a redução do teor de água, para a cultivar ‘Rajada’ e ‘Jacarezinho’. Pode-se observar que as sementes da abóbora ‘Rajada Seca Melhorada’ possuem uma maior resistência à força de deformação em relação a “Jacarezinho’.

This article is devoted to the issues of the efficiency increasing for buckwheat seed production by reducing mechanical damage during mechanized processing. It is indicated that one of the possible ways to reduce grain damage by machines’ details on a mechanized line is to assess the degree of damage adequately. Due to the fact that the samples analysis for mechanical damages taken from a grain batch that has passed according to any technological processing scheme is a labor-intensive and time-consuming procedure, the reliability of the results of which is largely dependent on the human factor, it is proposed to increase accuracy measurements on the basis of reliable experimental data, reveal the patterns of injury depending on the state of the grain material and its physical and mechanical properties, and in accordance with this, in the future, predict the quantitative increase in mechanical damage in general and by the types of injuries inflicted on the grain by a particular machine by using mathematical relationships. There are the theoretical dependence for the mechanical damages indicators on the number of passes through the machine and experimental dependence on humidity in this article established by using Markov chains. It was revealed that with mechanized processing there is a process of successive transition from less dangerous injuries to more dangerous injuries. The indicators of mechanical damage prediction will permit to compare the efficiency of individual machines of the production line in terms of their damaging ability and purposely design the technological process with minimal damage of the grain material.

The macáçar bean is a crop used in food, being of great economic and social importance, because present high nutritional value. With the expansion of large-scale macáçar bean production it is necessary to improve machines in order to avoid insults in the integument due to mechanical damages at harvest time. Thus, the objective of this work was to evaluate the mechanical properties of bean pods as a function of the different moisture contents obtained with drying. Manatee beans harvested manually, with an initial moisture content of 2.38 (decimal b.s.) in the municipality of Santa Helena de Goiás (GO). The moisture contents (0.73, 0.71, 0.66, 0.50, 0.38, 0.35, 0.18, 0.11, 0.05, decimal bs) were obtained by drying furnace with forced ventilation, maintained at a temperature of 50 ºC. The samples were submitted to uniaxial compression in natural resting position in the texturometer equipment. According to the results obtained, it is concluded that the moisture content influences the mechanical properties of the macáçar beans. As the moisture content decreases, it reduces the absorbed energy and the breaking force and the proportional modulus of deformity increase. The reducing the moisture content provides the grains with greater impact resistance during product preprocessing.
