    Abstract: The invention relates to a dryer for drying fuel materials such as wood bark, wood chips, sludge, garbage, peat moss or the like. In a preferred embodiment the dryer comprises a conveyor, consisting of twin endless belts, which carries the material to be dried along a vertical path defined between parallel runs of the endless belts, and ductwork which serves to direct heated air (received from any appropriate source) across the vertical path to remove moisture from the material as it is being conveyed. The ductwork includes at least one feed duct for use in delivering the heated air to one side of the vertical path, and at least one exhaust duct for use in withdrawing moisture-laden air on another side of the vertical path.

    Abstract: [Object] To provide a method for detecting water in plastics and a water removal system for plastic materials that enable an amount of water contained in a plastic to be measured accurately and rapidly. [Solution Means] A plastic 13 of known moisture state is irradiated with electromagnetic waves of a bandwidth of 50 GHz to 1000 GHz from an oscillating apparatus 11 and remaining electromagnetic waves not absorbed by the plastic 13 are received and measured by a receiver 12 to acquire a first measurement value in advance. The plastic 13 of unknown moisture state is then irradiated with the electromagnetic waves of the bandwidth of 50 GHz to 1000 GHz from the oscillating apparatus and the remaining electromagnetic waves not absorbed by the plastic 13 are received and measured by the receiver 12 to acquire a second measurement value. The first measurement value and the second measurement value are compared to compute the moisture state of the plastic of unknown moisture state.

  • Publication number: 20110247233
    Abstract: The present invention provides a method and system for drying coal using activated alumina. The method and system dries the coal by combining coal with the activated alumina. While in combination, the mixture is agitated to maximize surface contact between the activated alumina and the coal. As the coal contact the activated alumina, the surfactant moisture on the coal is then absorbed by the activated alumina. The activated alumina allow for the water molecules to pass into the sieves, thus being removed from the coal. After a period of agitation, the method and system thereby separates the activated alumina and the coal.

  • Patent number: 6438862
    Abstract: The invention is a distributed airways airflow dryer system for coffee beans and other such bulk crops. The interior volume or container of the dryer or dehydrator system that holds the bulk crops, is filled with an airways network structure that provides uniformly distributed open wall airflow passageways in the bulk crops. The airflow passages communicate with airflow openings in the walls or bottom of the container, to divide and admit the drying airflow into and through the full volume of the bulk crops as a large number of individual airstreams. Corrugated, ribbed, or cross-ribbed airflow plates are preferred embodiments that provide narrow open grooves or channels that expose the beans or kernels of the bulk crop directly to the airflow. This results in faster drying and greater uniformity of the drying effect on the full volume of the bulk crops.

The front wall has an opening aligned with the opening into the blower. The rear wall has an opening aligned with the opening in the front wall so that the majority of the air entering the blower passes straight through the housing from the rear wall to the front wall. A sleeve surrounds the opening in the rear wall and induces some flow from the housing to mix with the flow into the blower. The combustion chamber is attached to the rear wall through an opening in the rear wall above the sleeve. The housing has two side walls converging to an open top through which air can escape. When heated air is required an air flow is induced from the combustion chamber to mix with the air flow through the housing to heat the total air flow.
