The present invention provides a thermal evaporator with a cylindrical tube that is heated by one or more gas ignition burners. The tube is rotatable about the base. Rotational combination of both tube and agar provides enhanced evaporation performance.

Referring first to FIGS. 1 to 5, the same reference numerals denote the same members, wherein the apparatus 10 comprises a cylindrical tube 12 with two ends 14, 16. The tube 12 is equipped with at least one support wheel 18 at each end 14, 16. The roller 20 is rotatably mounted to the base 22 in contact with the support wheel 18 in a supporting relationship such that the tube 12 is rotatable relative to the base 22. The first drive means 24 applies a rotational force to the tube 12 and comprises a suitable chain, sprocket, gear reduction unit, and variable speed DC electric motor.

The fixed wet material input chamber 26 is fixed to the base 22 at one end 16 of the tube 12. The fixed dry material and product vapor release chamber 28 is secured to the base 22 at the other end 14 of the tube 12. The ends 14, 16 of the tube 12 extend into the unitary chambers 28, 26. Hot seals (not shown) at ends 14 and 16 prevent leakage of material and vapor.

The baby 30 has two ends 32, 34. The agar 30 extends through the tube 12 and the fixed chambers 26, 28. The agar 30 has a hollow central shaft 36 and is rotatably mounted in the tube 12 and is supported for rotation by the chambers 26, 28 at each end 34, 32.

The second drive means 38 applies a rotational force to the agar 30 and comprises a suitable chain, sprocket, gear reduction unit, and variable speed electric motor.

The insulating cover 40 for the tube 12 is sized with an annular space 42 in the cover 40 with respect to the tube 12. The plurality of gas ignition burners 44 communicate with the annular space 42 to heat the outside 44 of the tube 12.

In a preferred embodiment, the conduit 46 connects the annular space 42 to the end 34 of the agar hollow shaft 36 in the wet material input chamber 26 via the blower 48. In some cases, the advantages of the present invention can be obtained without the use of conduits 46.

The conveying means 50 is provided such that the wetted material 52 is conveyed into the wetted material input chamber 26 and into the inner annular space 54 of the tube 12 and to the outside 56 of the agar 30.

The discharge means 58 is provided to receive the dry material 60 at the bottom end 61 of the dry material and product vapor discharge chamber 28.

The first venting means 62 is connected to the top 64 of the drying material and product vapor evacuation chamber 28 for discharging the smoke 68 from the tube 12 and the chamber 28. The second venting means 70 is connected to the end of the agar hollow shaft 36 in the drying material and product vapor discharge chamber 28 for discharging the combustion gas 72. The third venting means 74 discharges the remaining combustion gas 76.

The control panel 78 is provided for burner and DC motor speed control. The air treatment device 80 may be selectively provided to discharge the first venting means 62. Conveyor 82 may optionally be provided for handling the dry material produced by the device.

During operation, the device 10 is equipped with a main component wintling tube 12 with large diameter steel support wheels 18 at both ends. These wheels 18 are located on a roller 20 mounted to the base 22 to allow rotation of the dehydration chamber provided by the tube 12. The chamber is powered by a variable speed DC motor and driven by a sprocket and chain attached to the gear reduction unit. Both the "wet end" (wet material input chamber 26) and the "dry end" (dry material and product vapor discharge chamber 28) are fixed chambers. The dehydration chamber extends into these chambers. Hot seals located at the ends of the chamber prevent leakage of material and vapor.

A specially manufactured screw agar with a flight located on the hollow shaft extends through the center and fixed end of the dehydration chamber. This agar 30 is also driven by a sprocket and chain attached to a gear reduction unit powered by a variable speed DC motor. The rotary drying chamber is enclosed in an insulated metal cover 40 with several inches of air space left between the insulated metal cover and the tube 12. Heat from the gas ignition burner 44 is introduced into this annular space through a plenum located in the lower section of the annular space 42 before exiting to the atmosphere. This method allows the slowly rotating chamber to be heated evenly around the entire diameter. When necessary, a portion of the hot combustion gas can be attracted from the annular space 42 by the blower 48 and can be injected into the "wet end" of the hollow agar shaft 36. They are also released into the atmosphere at the "dry end" of the system.

The dewatered material 52 may be metered into the chamber 26 by a variable speed screw agar or metering pump. The wet material is subjected to indirect heating of the chamber wall and, if desired, to indirect heating of the heated hollow agar shaft. Dry material 60 is discharged from the dryer tube through the bottom of the "dry end" fixed chamber. Vapor from the product is released from the top of this end. The type and composition of the material and the requirements of the Office of Air Quality Control, which must be tailored to the particular area, will determine the type of air handling device 80 required.

On the other hand, while the present invention has been described with respect to specific embodiments, those skilled in the art can make various modifications and changes, which will fall within the scope of the appended claims.
