| 摘要 |
The present invention provides a drying device for coagulating and/or drying a fluid material having significant solids content, such as animal blood, to produce a dried solid product where the device includes generally an upwardly sloped elongate housing of generally semicircular cross section of selected diameter to define a coagulation chamber where the top of a portion of the chamber can be open, heat source means to selectively heat the housing, elongate screw conveyor means disposed within the housing with its longitudinal axis parallel to the longitudinal axis of the housing where the screw conveyor has a shaft with generally continuous helical blade means extending radially therefrom and having an outer diameter approximately equal to the interior diameter of the chamber and where the screw conveyor is adapted for rotation in the chamber to agitate the fluid in a portion of the housing and to convey solid material from a first lower end of the housing, toward a second, higher, end of the housing for emission, vapor emission means located at a selected position between the first and second end of the housing for emission of vapor from the housing, cover means to cover the portion of the housing, and the screw conveyor, between the first end of the housing and the vapor emission means, and where the screw conveyor means includes spaced finger means extending radially from the shaft of the screw conveyor means toward the sidewall of the housing between the blades of the screw conveyor means in the area of the housing between the vapor emission means and the second end of the housing.
