Ensilaging of beet pulp with the use of wrapping press
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 4
Abstract
The work determines the economic and material inputs occurred during ensiling of beet root pulp in the form of cylindrical bales with different "binding" methods, by net or foil and various number of utilized film layers during wrapping and described as: TSW, TSA and TP. A computational algorithm was developed that allowed to determine the criterion for which the following was assumed: fuel consumption, labor inputs and costs related to the unitary dry matter of ensiled pulp at the actual humidity and calculated to dry matter of the substance. In addition, a cost structure was developed, shared into the costs of: machinery and equipment, fuels, labor and auxiliary materials. The analysis of total unitary costs shows that in TSW and TSA technologies the costs are equal approximately. PLN 110 PLN ∙Mg d.m.-1, while TP technology is equal PLN 87.80 ∙Mg d.m.-1, and therefore they are smaller by 20%. The structure of costs has the largest share in costs occurred for auxiliary materials, which range from about 74.00 PLN Mg d.m.-1, in variants TSW and TSA up to 51.30 PLN∙Mg d.m.-1 in TP, which is equal approximately to 67 and 52% of total costs. The share of costs of machinery and equipment utilized is also significant, and amounts to 30 PLN∙Mg d.m.1, which is equal to 27.5% in TSW and TSA technologies and 35% in TP technology.
