Determination of maximal slipping of wheeled movers taking into account the limiting of their impact on soil

Nadykto V.T.

Abstract

To ensure the minimal damage of soil structure, it is proposed to determine the maximal slipping of wheeled movers taking into account the value of their permissible pressure on soil in horizontal plane. As a result, it is established that for the substantial reduction of soil structural damage during agricultural works in spring period the maximal permissible values of slipping of wheeled movers of tractors of 5, 3 and 1,4 tractive classes have to be equal to 15, 12 and 9% respectively. In summer and autumn periods, the values of maximal slipping can be greater and, accordingly, be equal to 20, 16 and 13%.

Theoretical and experimental studies of infrared drying of heat-labile materials

Golubkovich A.V., Pavlov S.A., Levina N.S.

Abstract

Drying of high-moisture and heat-labile material requires the substantiation of temperature and duration of process. This is due to the necessity of preserving of product quality and economical efficiency of process. Use of infrared drying allows to solve this problem, because the duration is significantly reduced in comparison with convection drying.
