A dewatering device for aggregate product can be used to retro-fit existing aggregate product dewatering facilities in order to more efficiently capture product. The dewatering device can be movable to allow for the portability of the device relative to existing dewatering facilities. The device is adapted to receive a slurry of aggregate product and water and to vibrate to dry the aggregate product. A recycle system is included to receive any fines that may otherwise be lost by the system. The recycle system captures the fines and redirects them back towards the vibrating process of the vibrating device to direct them towards an exit of the vibrating device in order to use said fines as well as the other dewatered aggregate product. The portability of the device allows the device to be used with the existing facilities without the need to completely replace existing components for dewatering aggregate product.

A vibratory fluidized bed dryer includes a deck with a surface on which a bed of materials is formed, the deck having apertures through which air passes to fluidize the bed of materials on the deck, a source of air coupled to the apertures in the deck to supply air to the bed through the apertures in the deck, and a vibration generator coupled to the deck. The deck has at least two zones, each zone having a different open area percentage, such that the air passing through each zone produces a different superficial velocity.

The invention relates to a method for drying moist products, in particular moist granules for producing pharmaceutical products through which a fluid medium flows in a reactor chamber of a bulk goods dryer and which are heated and placed on a fluid medium-permeable inflow base. The inflow base is vibrated via a vibrational drive in order to convey the products from a product inlet to a product outlet, and the fluid medium is supplied to separate chambers arranged upstream of an outlet and to the outlet after flowing through the inflow base and the product. One of the at least two separate chambers is preselectably closed off from the outlet by actuating a closing element such that after the closing element has been actuated, the supply of the fluid medium to the outlet is carried out via a chamber which is not closed by another closing element, and a fluid medium filter element paired with the closed chamber is cleaned via a pulse emitter after the closing element of said chamber is actuated in the closing direction while the fluid medium is continuously supplied to a non-closed chamber.
