Abstract:
1. A method for unloading a viscous product from a tank trailer for transporting and storing a viscous product and comprising a housing having an interior, and a plurality of vibrating devices positioned along the housing, wherein the plurality of vibrating devices includes at least three pairs including a front pair of vibrators, a middle pair of vibrators and a rear pair of vibrators, and the plurality of vibrating devices are configured for a discrete and staggered pulsing operation, the method comprising: forcing the viscous product, during unloading of the tank trailer, from the interior of the housing to the outside, thereby reducing an amount of product remaining in the interior following the unloading, wherein forcing the viscous product from the interior of the housing comprises utilizing the plurality of vibrating devices including a first plurality of vibrating devices positioned along the housing, and a second plurality of vibrating devices positioned opposite the first plurality of vibrating devices; wherein the viscous product comprises a viscous liquid food or non-food grade product and/or a liquid with solid in suspension, and further wherein the discrete and staggered pulsing operation is carried out such that the front pair of vibrators is pulsed first, followed by the middle pair of vibrators, and then the rear pair of vibrators to force the viscous product from the interior of the housing or such that the rear pair of vibrators is pulsed first, followed by the middle pair of vibrators, and then the front pair of vibrators to force the viscous product from the interior of the housing.
