The results of an experimental investigation of the effective thermal conductivity of a vibrofluidized bed in the vertical direction are given. A pulsating change of temperature decreasing with time, bearing witness to the essential influence of the convection of particles on the internal heat transfer in the vertical direction, is observed at the time of creation of a heat pulse in the bed. The method of bed 'freezing' is used for the visualization process. The influence of the parameters of vibration on the effective thermal conductivity of the vibrating bed is discussed, and a quantitative evaluation of its anisotropic character is given.
