A process for augmenting energy in a dryer used in processing is disclosed. The process includes providing a source of syrup having concentrated solids. They syrup is then directed through a syrup line to a recirculation pump where it is recirculated to a heat exchanger having a source of heat delivered thereto. The syrup is heated to a temperature above a flash point of the syrup. The heated syrup is delivered to a flash tank and water vapor is flashed off and then directed through a vent and into a dryer. Cooled syrup remaining in the flash tank is delivered through a cooled liquid line to the syrup line to repeat the process. The delivery of water vapor to the dryer results in an additional source of energy being transferred to the dryer.

The noodle driving apparatus includes an enclosure having a lateral partition separating the enclosure into an upper chamber and a lower chamber. At least one first cool-air provision device and at least one warm-air recovery device are disposed to a side inside the upper chamber. A number of first cool-air inlets and warm-air inlets are configured on the partition toward another side of the upper chamber. Noodles to be dried are placed in the lower chamber. Cool air produced by the first cool-air provision device is introduced into the lower chamber through the first cool-air inlets to absorb moisture from the noodles. Warm air produced from the first cool-air provision device is collected by the warm-air recovery device and introduced into the lower chamber through the warm-air inlets to dry the noodles. The noodle driving apparatus thereby achieves improved drying performance, enhanced energy consumption, and better drying quality.

A device for controlling the temperature of, and in particular for drying, objects, in particular vehicle bodies, having a housing which integrates a temperature-control chamber that includes at least one air outlet and at least one air inlet. The temperature-control chamber is assigned at least one heating unit in which it is possible to generate a hot primary gas flow and to which it is possible to supply, from the air outlet, air that is to be heated. The heating unit includes a heat exchanger device into which the hot primary gas can be guided and in which it is possible to heat air from the temperature-control chamber using hot primary gas, which air can be supplied, as heated recirculation air, in a circuit via the at least one air inlet back to the temperature-control chamber. The heating unit includes at least a first and a second flow outlet via which heated recirculation air leaves the heating unit.

A grain dryer has an upper plenum in communication with a pair of heating columns. Each heating column has an inner boundary and an outer boundary being formed with a plurality of angled containment baffles configured to funnel grain down the heating column while allowing heated air to be drawn from the upper plenum through the grain. At least one fan takes a suction from the ductwork to draw heated air from the upper plenum through the heating column such that grain is exposed to heated air. The orientation of the containment baffles forming the inner boundary directs the flow of the heated air in a downward direction through an inner portion of a grain column between the inner boundary and the outer boundary, and the orientation of the containment baffles forming the outer boundary directs the heated air in an upwards direction in an outer portion of the grain column.

A grain dryer has pair of heating columns in communication with an upper plenum, and a pair of cooling columns in communication with a lower plenum. A heater is located between the lower plenum and the upper plenum, wherein air is heated by the heater as air in the lower plenum is pulled through the heater and into the upper plenum. As the grain flows into the cooling column, it is exposed to cooling air being pulled through the cooling column into the lower plenum. A cooling air bypass system having a plurality of bypass tubes brings bypass air into the lower plenum from outside the grain dryer without having the bypass air come into contact with the grain being cooled in the cooling section. The cooling air bypass system includes a grill with an adjustable damper to adjust the amount of bypass air that flows into the lower plenum.

Ductwork adjacent each heating column includes vertical sections arranged along a length of the grain dryer. Each vertical section has a fan located adjacent the uppermost horizontal level of the heating column. Each fan takes a suction from the ductwork to draw heated air from the upper plenum through the heating column.

Systems and processes provide for a thermal process to transform sludge (and a variety of other natural waste materials) into electricity. Dewatered sludge and other materials containing a high amount of latent energy are dried into a powdered biofuel using a drying gas produced in the system. The drying gas is recirculated and is heated by the biofuel produced in the system, waste heat (from turbines or internal combustion engines), gas (including natural gas or digester gas) and/or oil. The biofuel is combusted in a boiler system that utilizes a burner operable to burn biofuel and produce heat utilized in a series of heat exchangers that heat the recirculating drying air and steam that powers the turbines for electricity production.

The present invention relates to installations comprising a contact dryer and a vapour compressor. The invention also covers processes using an installation comprising a contact dryer and a vapour compressor for drying a water-containing composition of solid matter with a higher energy efficiency. Furthermore, the invention relates to the field of energy recovery from contact dryers.

The present invention relates to a process for continuous of drying or removing the water phase from wet material, such as organic material and for regulating or controlling the drying mechanisms using heating and drying components in a mechanic set up for drying material. The steam generated in the pre-dryer in the process is sufficient to sustain the energy need of the system as the different components of a meal factory are set up as a closed system.

An air drying unit for compressed air systems is provided. The air drying unit has a precooler/reheater, a main cooler and a moisture separator. Incoming air is cooled to cause moisture within the compressed air to condense, which is then separated to dry the compressed air. The precooler/reheater, main cooler and moisture separator are designed as an integral unit that does not require pipes to connect the components together. Instead, compressed air flows through the sealed unit through passages therein between the precooler/reheater, main cooler and moisture separator.
