The heater may be thermostatically controlled to maintain the temperature of the heated fuel to a value that is at or above a temperature required for good fuel atomization but below a flashpoint of the fuel. A valve is provided in the return line to permit diversion of the returned fuel to the fuel tank during a purge operation at initial startup.

Abstract: A method of drying and buffering organic moist products, particularly food items. Introducing the product into a first chamber, bringing the first chamber to a first reduced ambient pressure, feeding microwave energy from a microwave source so as to increase the temperature and buffer the moist product, and increasing the reduced ambient pressure to a less reduced second ambient pressure multiple times and subsequently reducing the ambient pressure to the first reduced ambient pressure. Wherein the increase of the ambient pressure is carried out faster than the reduction thereof, followed by a final drying of the product in a second chamber while feeding infrared radiation at a third (reduced) ambient pressure. Subsequently, the product is cooled and discharged into the atmosphere. Thus, increased product quality, in particular a more consistent and more stable product is obtained.

Abstract: An improved spiral oven and method for its use includes the step of using a forward/reversing fan to produce a first airflow and a second inverted airflow in the cooking chamber. The proportion of time each airflow occurs may be unbalanced within an oven residence time or cook cycle, and either airflow may begin the cycle. In addition, the fan velocity may vary so that the speed of the first airflow is different from the speed of the second airflow. A braking resistor allows the fan to quickly changeover between full-forward and full-reverse directions, while a programmable delay limits adjustments to the heat output control method until temperature variations caused by alternating between the first direction of rotation and the second direction of rotation have stabilized. Because of the reversing airflow pattern, the product cooks more evenly across the cook belt.
