Twin screw extruder with conical non-parallel converging screws
The present invention is broadly concerned with improved twin screw extruder a highly versatile nature which can be used for the production of a wide variety of end products of varying densities, cook values and expansion ratios, without the need for extensive machine modifications. The extruders of the invention include a twin screw assembly having non-parallel, tapered conical screws with the flighting of the screws intercalated along the length of the twin screw extruder barrel to define close-clearance, preferably constant dimension, alternating upper and lower nip areas and trailing kneading zones and reverse flow passageways; the nip areas create high pressure zones within the barrel which propel material forwardly, while the material is kneaded and allowed to reverse flow in the zones and passageways. In other embodiments, an infinitely variable die assembly including a shiftable stem movable between a waste disposal position and a variety of extrusion positions. A specialized fluid extraction final extruder head is also provided, which allows oils or other fluids to be efficiently extracted, particularly with the aid of a supercritical extractant such as carbon dioxide.
However, most prior twin screw extruder must be designed with screw and barrel section configurations which are specific to a desired product. That is, the configuration used for the production of high density aquatic feeds is generally significantly different than that which would be necessary to produce medium density pet foods or low density feeds. As a consequence, the extruder must be broken down and reconfigured if it is desired to change the product to be produced. Moreover, in some cases an extruder designed for one type of product simply cannot be reconfigured successfully to efficiently produce a significantly different type of product.
There is accordingly a need in the art for improved twin screw extruder equipment of great flexibility and versatility and which can be used to yield dissimilar products without extensive reconfiguration or reworking of the internal extruder components; moreover, improved equipment for the extraction of high quality oils and the like while avoiding the problems of solvent extraction would be an important breakthrough.

related rates!!! help! using implicit differentiation?
wheat is poured through a chute at the rate of 10 ft^3/min, and falls in a conical pile whose bottom radius is always half the altitude. How fast will the circumference of the base be increasing when the pile is 8 ft high?
(please help!!! i need before 11pm today plz!!!)
V = π r² h---> here V = π r² [2r]
C = 2πr...find dC / dt ....dC / dt = 2 π dr / dt
but dV / dt = 10 = 2π {3 r² dr / dt}...at h = 8 --> r = 4
find dr / dt and then dC / dt...you can do that
