The present invention relates to a new device and a way to assemble such a device for both cooking and drying organic material in the process of making meal. The device of the present invention has a large area for heat exchange and scrapers which stir the material in the container rather than transferring it around in circles. The method of assembling the device allows an accurate and convenient assembly so that the scrapers thoroughly scrape all inner surfaces of the device.

The invention relates to a device for the heat treatment of a product, comprising an enclosure, means of conveyance inside the enclosure, which comprise a screw mounted so as to rotate in the enclosure about a geometrical rotational axis and means for rotating the screw about said axis, and means for heating the screw by Joule effect. According to the invention, the screw comprises a strip which is made of an electrically insulating material and is applied to the screw so as to form an outer circumference of the screw.

The present invention relates to a process for continuous of drying or removing the water phase from wet material, such as organic material and for regulating or controlling the drying mechanisms using heating and drying components in a mechanic set up for drying material. The steam generated in the pre-dryer in the process is sufficient to sustain the energy need of the system as the different components of a meal factory are set up as a closed system.

To provide a drying method for terephthalic acid and a horizontal rotary dryer allowing easy performance of mass processing of the terephthalic acid and enabling size reduction by improving drying performance of the dryer. In a method of drying terephthalic acid by using a horizontal rotary dryer, a rotating shell is rotated to make a critical speed ratio defined by expression 1 and expression 2 become 17 to less than 80% to dry the processing material,
Vc=2.21DExpression 1
=V/Vc.Math.100Expression 2 wherein Vc indicates a critical speed (m/s) of the rotating shell, D indicates an inside diameter (m) of the rotating shell, indicates the critical speed ratio (%) of the rotating shell, and V indicates a rotation speed (m/s) of the rotating shell.

Implemented is an apparatus and a process for complete treatment of slurry and powder. The apparatus includes a rotatable lower bowl assembly, a rotatable upper bowl assembly adapted to be assembled with the lower bowl assembly, a drive including at least a geared motor, connected with each of the lower bowl assembly and the upper bowl assembly. A main frame assembly movably mounts the lower bowl assembly and the upper bowl assembly. The lower bowl assembly and the upper bowl assembly are assembled together to form a spherical bowl assembly in a vertical orientation, on the main frame assembly. The spherical bowl assembly receives the slurry for treatment, processes the slurry into a dried product after treatment, and safely discharges the dried product out of the spherical bowl assembly.
