The productivity of most grain cleaning machines seems to be directly related the efficiency vertical pneumatic separation ducts. Nevertheless, improvement is accompanied by an increase in load duct, design which limited width machines. This requires thickness layer mixture that enters working area significantly worsens conditions its components under action airflow. Particles light impurities are unable separate due their retention medium. reduces quality and appropriate scientific...

The paper presents the results of an evaluation quality eggs from laying hens kept in caged and free range systems using traditional methods ultra-weak luminescence (USL). It was found that tested were fresh characterized by required quality, as demonstrated analysis egg white yolk. Eggs free-range eight-fold higher emission photons compared to hens, they had over three times content natural antioxidants form carotenoids. Most probably, number emitted is associated with a biologically active...

The pulsed electric field (PEF) is one of the non-thermal methods used in food industry for prolonging preservation or obtaining better quality end products. structure fruit and vegetable tissues subjected to PEF treatment changes under influence short-term high voltage electrical impulses. In this process, hydrophilic spaces cell membranes occur. authors present results assessment structural PEF, using textural analysis sub-peel layers. images were obtained by optical coherence tomography...

Abstract Evaluation of harvest and postharvest treatment quality the grains is affected by usage appropriate equipment technology. The grain damage depends on its physical mechanical features. corn planting has significant representation in European conditions, mainly for food industry purposes. In work, we were focused observing drying temperature’s impact micro-damage seeds. solution issue described work closely related to preparation education project KEGA 039SPU-4/2017, a scientific...

The paper presents the results of influence light different wavelengths and pulsed electric fields on content carotenoids. Seeds germination was carried out in a climatic chamber with phytotron system. experiment under seven growing conditions differing light-emitting diode (LED) using (PEFs) strength applied before sowing. Cultivation sprouts for days at relative humidity 80% 20 ± 1 °C. Different were used during cultivation: white (380–780 nm), UVA (340 blue (440 red (630 nm). In addition,...

Due to technological progress in forestry, seedlings with covered root systems—especially those grown container nurseries—have become increasingly important forest nursery production. One the trees that is most commonly this way common oak (Quercus robur L.). For an acorn be sown a container, it necessary remove its upper part during mechanical scarification, and evaluate sowing suitability. At present, mainly done manually by visual assessment. The low effectiveness of method preparation...

The basic principle of silviculture is the rational use natural regeneration. acceleration and equalisation seed germination an increase field ability are affected by scarification, which results in destruction or weakening cover. Acorn scarification performed manually, standing position, most often adapted work stations, whose geometry adjusted staff to their own anthropometric dimensions. An added value acorn consists visually assess health status cotyledons visible on cross-section,...
