Apparatus for carrying out fluidized operations including a housing defining an upper chamber and a lower chamber, with each of the chambers containing agitating means therein to insure a high degree of homogeneity in each of the chambers, a plurality of tubes enclosed in a jacket positioned between the upper and lower chambers and communicating therewith, the tubes providing large heat transfer surfaces, inlet means to supply a fluidizable material to the one chamber and outlet means to remove fluidizable material from the other chamber, and means to supply a fluidizing gas to the lower chamber whereby the fluidizing gas passes upwardly through the lower chamber and through the tubes into the upper chamber while fluidizing the material in each of the upper chamber, the tubes and the lower chamber. The apparatus of the invention is particularly well suited for converting starches to dextrin. |
