Abstract: A reflectometer system for use with a non-contact actinic system includes a primary lens, and an illumination source and a detector positioned on an observation side of the primary lens opposite a goods production area and sample region. The illumination source emits an illumination beam through an illumination beam void between the primary lens and the housing, which is directed into the goods production area and sample region, and onto a flow or static sample of material to be tested. The material being tested then create a reflected beam, which shines back to the observation side of the primary lens through the primary lens to the detector. The general alignment of the illumination beam and the reflected beam create an extended sample region within the goods production area, as well as a compact reflectometer system structure.

Abstract: Coffee beans are roasted with heated air in a roasting chamber, and contaminant-laden exhaust air including caffeine entrained therein is discharged from the chamber. While roasting is in progress, the exhaust air from the chamber is heated, directed through a catalytic converter and cooled to a temperature between about 250° F. to 325° F. Thereafter the cooled exhaust air flows through a cooler or condenser where the temperature of the cooled exhaust air is further lowered to between about 100° F. and 155° F., and it is then directed through a HEPA filter to remove caffeine particles that are present in the cooled air. Substantially caffeine-free clean exhaust air can then be discharged from the HEPA filter directly to the surroundings of the roasting machine such as a closed room, e.g. a retail establishment, frequented by persons.

Abstract: An apparatus and method of roasting foodstuff such as coffee beans employ a roasting chamber for roasting the beans. An air circulation system operatively coupled with the chamber flows heated air over the beans and thereby roasts the beans, and an air cleaning arrangement is operatively coupled with the air circulation system and located downstream of the chamber for removing substantially all particulates, smoke and volatiles entrained in the used air as it flows through the container and into the air cleaning arrangement to provide substantially pollutant-free used air. The circulation system uses atmospheric air and heats, cleans and cools it within as little as ¼ second. Sensors and a electronic controller are provided to monitor various parameters in the roasting apparatus and control the roasting characteristics. The darkness and/or color of the beans during roasting is monitored to ensure proper roasting.
