    The paper presents experimental research results under laboratory conditions of the technical equipment for harvesting Miscanthus rhizomes in order to establish constructive and functional parameters: lengths,widths, total heights, constructive working depth, clearance, ground gauge, mass values, checking the machinery coupling to the tractor,rotation frequency of separator driving shaft, amplitude and frequency of separator grate movement. The results obtained confirm fulfilling the requirements regarding to constructive and functional parameters of Miscanthus rhizomes harvesting equipment.

    EXPERIMENTAL RESEARCHES ON THE WORKING QUALITATIVE INDEXES OF TECHNICAL EQUIPMENT FOR HARVESTING MISCANTHUS RHIZOMES

    Get PDF
    The article presents the results of experimental research of the technical equipment for harvesting Miscanthus rhizomes, in order to determine the following working qualitative indexes: the percentage of extractedrhizomes, the degree of rhizome damage, rhizome losses at harvesting, the content of impurities in the mass of rhizomes and the degree of separation of extracted rhizomes. The results obtained in the experimental researches help improving the equipment for harvesting Miscanthus rhizomes in order to meet the quality requirements of the work.Experimental researches were carried out under field conditions, on the experimental plot of INMA Bucharest, the development stage of energy plant Miscanthus being in the 7th year of growing

    MODERN METHODS FOR FREEZING USED IN FOOD INDUSTRY

    Get PDF
    Foods have a limited duration of preservation, due to factors that worsen quality,leading ultimately to their total depreciation. In order to preserve perishable foods and prolong the allowable period for storage and sales, one of the best methods that use artificial cold is freezing. The paper aims to present the most used methods of freezing food, focusing on the advantages and disadvantages of these methods

    CONSIDERATIONS ON THE IMPORTANCE OF SEED SEPARATION TECHNOLOGY BY AERODYNAMIC PROPERTIES

    Get PDF
    The article is aimed at agricultural entrepreneurs interested in the implementation of organic seed production technologies in their own units with the help of the Seed Cleaning Installation - ICS.In order to store, process or capitalise the agricultural products resulting from the harvesting process, they must undergo a pre-cleaning process that can be done depending on the aerodynamic properties of the seeds

    CONSIDERATIONS ON THE IMPORTANCE OF JERUSALEM ARTICHOKE CROP IN HUMAN AND ANIMAL FEED

    Get PDF
    This paper aims to provide rich and updated information on the importance of the crop of Jerusalem artichoke (Helianthus tuberosus(fig.1) [8] - Astaraceae or Compositae family) in human and animal feed. Jerusalem artichoke is a plant that can be used in animal and human feed, as windbreaks in agriculture, for manufacturing pellets for heating installations, etc. Inulin, a group of oligosaccharides, is used in the food industry because of its particular nutritional characteristics
