Patent number: 6701829Abstract: Two steel plates with perforations in both sheets have narrow bent edges which overlap when the two plates are placed together to for a rapid smoker with approximately ¾ inch between the plates. A layer of wood chips is placed in the rapid smoker and the smoker placed directly on the heating source of any type of grill. The wood catches fire quickly through the bottom perforations and sends smoke through the top perforations. The perforation are configured in the top and bottom steel plates in such a way as to accomplish rapid ignition of wood producing smoke and control of the burning/smoking process. This process produces two cooking zones and adds additional favor to the cooked food.Type: GrantFiled: May 20, 2002Date of Patent: March 9, 2004Inventor: Samuel Farrow

Patent number: 6701830Abstract: Above-ground tanks form brining cells into which cheese blocks are conveyed by common inlet and outlet flumes. Each cell has a removable conveyor assembly having a looped link belt driven around a frame by a motor. Perpendicular, tubular, or hinged segmented flights project from the belt to engage infed cheese blocks, and submerge a series of rows of blocks. An infeed flume delivers a stream of cheese blocks to a cell. Once a level below a flight is filled, the conveyor is actuated to submerge that level, and the next level is then filled until the tank is filled. After brining, the conveyor is incremented to discharge the cheeses flight by flight into an outlet flume. The flume may have a lower segment narrower than an upper segment, such that by draining the tank smaller cheese blocks may be better controlled.Type: GrantFiled: March 18, 2002Date of Patent: March 9, 2004Inventors: Scott J.
