Abstract:
1. A method for performing forced immersion oscillatory cleaning of product arranged in a tank, a rigid frame being arranged at a bottom of the tank, the method comprising: filling the tank with a fluid, the tank including a membrane sealed about an upper open perimeter of the tank via a first seal and receiving the product to be cleaned in the fluid, the rigid frame being further sealed at a bottom of the tank via a second seal; applying pressurized air or gas to the membrane via a first pump in communication with the tank via a first hose to cause the membrane to conform to the product arranged in the tank; applying continued air or gas pressure to fluid forced out of an area between the tank and the membrane and forced into a center cavity of the tank to force the rigid frame to rise upward toward the upper open perimeter of the tank until a level of the fluid level is forced beyond a bottom of the rigid frame, the air or gas being discharged from under the rigid frame such that the rigid frame returns downward to the bottom of the tank within the center cavity of the tank; and repeating the process during pressure gradient fluctuations to develop a consistent rhythmic oscillation which creates a movement of the rigid frame and product in the center cavity of the tank to repeatedly transfer the fluid through the product to clean said product.
