  • Patent number: 10753684
    Abstract: An energy efficient a drying system and process using heated, dry air. The system includes an air inlet, a heat pump evaporator unit, a heat pump condenser unit, a drying unit, a heat exchanger unit, a fan, and air channels for transport of airflow from the air inlet through the system. The fan causes air to flow into the air inlet through the heat pump evaporator unit and to maintain an airflow through the system. The heat pump evaporator unit is configured to use a refrigerant to absorb heat from air that flows into the system through the heat pump evaporator unit. The heat pump condenser unit is configured to release the heat absorbed at the evaporator to the airflow. The heat exchanger unit is arranged to transfer heat from the airflow leaving the drying unit to the cold, dehumidified air flowing from the heat pump evaporator unit.

  • Patent number: 6047483
    Abstract: A heating system for a mechanical compressive shrinkage apparatus in which a continuously flowing liquid heat exchange medium is caused to flow in series through each of the components required to be heated. Heat is input to the flowing medium in accordance with the temperature of one of the components to be heated, preferably the first in the series. Uniformity and constancy of both absolute and relative temperatures of the series-connected components is achieved. A mixture of water and propylene glycol alcohol is an advantageous heat exchange medium for the purpose, which allows operation at lower pressure without the maintenance problems of a system using, for example, oil as the exchange medium.

  • Patent number: 6004468
    Abstract: An apparatus for processing a solid-liquid material comprises a housing formed with a series of interconnected chambers defined by chamber walls with at least two drums mounted in series within the chambers. Each chamber receives one of the at least two drums for rotatable movement therein. Each chamber and the associated drum are dimensioned to define a region therebetween to retain the solid-liquid material. The regions of adjacent chambers communicate with each other to define a continuous passage from drum to drum through the apparatus. An inlet in the housing admits the solid-liquid material to the passage, and an outlet permits extraction of a processed solid-liquid material from the passage. Each drum rotates in a direction opposite to the adjacent drum to advance the solid-liquid material through the passage from drum to adjacent drum in a sinuous path such that the curvature of the solid-liquid material changes when passing from drum to adjacent drum.

  • Patent number: 4945657
    Abstract: An improved multiple-pass drum dryer (12) is provided which includes an enlarged, flighted premixing zone (65) including a frustoconical, converging transition section (68) leading to an innermost passageway (138) of a concentric multiple-pass final drying section (24). Product and drying air fed to the premixing zone (65) undergo an acceleration in the transition section (68), whereupon product and air are decelerated during travel through the multiple-pass final drying section (24). In this way, product is moved along a first region (66) of the premixing zone (65) at a relatively low average speed so that the initially wet product is proximally exposed to heated gases emitted from a burner for a maximally effective time period. The product then experiences a relatively rapid acceleration in the transition section (68) due to negative pressure from a downstream fan and decreasing cross-sectional area in the transition section (68).

  • Patent number: 4894930
    Abstract: An improved, high efficiency rotary drum dryer and method is disclosed which achieves outstanding thermal efficiencies by provision of a multiple-pass rotary dryer designed so that the product to be dried is first conveyed through an outermost drum of relatively large cross-sectional area and then through succeeding internal drums of progressively smaller cross-sectional areas. In this way, the velocity of induced air currents traveling through the dryer increases from pass to pass, with the result that the net velocity of product through successive passes also increases. The preferred dryer also includes housing structure in surrounding relationship to the innermost drum permitting introduction of relatively low humidity ambient-derived air into the central drum so as to lower the partial pressure of moisture in the drying atmosphere, thus promoting the final stage of drying.

The predryer includes respective, adjacent, two-pass air and crop paths disposed within a tubular shell, and the entire predryer is axially rotated during operation thereof. The ultimate volumetric air discharge from the system is significantly reduced as compared with conventional rotary dryers, and the saturated wet scrubbing which occurs in the predryer displaces a high percentage of particulate matter from the gaseous discharge to the water discharge, thereby reducing atmospheric pollution.
