ABSTRACT:
An apparatus (10) with a central shaft (32) equipped with single or multiple-mixing elements (36) projecting perpendicularly from the shaft. Multiple processing zones (14-18) have adjustable openings (24) for introducing the product through adjacent processing zones for thermal treatment or conducting thermal reactions. A heating or cooling jackets (63 and 129) permits thermal control of the processing within the chamber. Additional thermal treatment can be achieved with micro-wave, infrared, hot gas or other available heating or cooling sources. The chamber is closed during vacuum or pressure processing by using rotary locks or double valving. A controlled dwell time in the chamber is accomplished with the adjustment of the opening of the weirs. The rotational velocity of the elements plays a major role in maintaining the material in the desired processing zone or causing advancement between adjacent zones. Continuous non-atmospheric pressure can be maintained without exposing vapors or product to atmospheric conditions by means of providing valving in the material input and material output. Chopping mills, pre-wetting devices and liquid/solid vacuum filtration can be added to enhance the function of the equipment. Processing may be extended in time with two or more apparatus connected in series or in parallel to provide additional processing capability.
