A device for drying sewage sludge having a modular design composed of standard containers, the standard containers being disposed behind and optionally on top of one another. Slabs including heating lines are introduced on top of one another, in multiple levels, into the standard containers, serving as drying surfaces. Linear conveyors including deflections in a first and a last container distribute the sewage sludge across a width of the drying surfaces, turn and loosen the sewage sludge, and move this successively back and forth over the drying surfaces disposed on top of one another.

The disclosure relates to a device (21) for producing a fertilizer and/or feed, comprising a chamber (26) having a first opening (27) for letting in an emulsion (14′) of wastewater (8, 9) and grease (14), and a second opening (28) for adding organic waste (16), a circulating element (29) arranged in the chamber (26) for circulating a mixture (14′, 16) of the added emulsion (14′) and the added organic waste (16), and a heating element (30) for drying the mixture (14′, 16) by evaporating water (31) from the mixture (14′, 16).

An oil sludge treatment system includes: a reduced-pressure fermentation dryer; a filtration apparatus; and a cleaner. The reduced-pressure fermentation dryer is configured to: store oil sludge in an airtight container; heat and stir the oil sludge under reduced pressure so that a temperature of the oil sludge is within a predetermined temperature range; decompose organic matter contained in the oil sludge using microorganisms while evaporating water; and obtain volume-reduced dried product. The filtration apparatus filters oil from the dried product. The cleaner cleans, by steam, the dried product from which the oil has been filtered.

A hemp biomass drying assembly that is disposed within a structure and having a central lift assembly, a rotatable tine assembly, an auger assembly, and a track drive assembly that are all connected to a control system to activate and operate all assemblies. The drying assembly has multiple modes of operation that include a spreading mode, a leveling mode, and stirring mode, and an unloading mode.

The present disclosure relates to a drying apparatus for a powder raw material for manufacturing a secondary cell with an electric heater. In an embodiment of the present disclosure, a plurality of independently controlled heaters are mounted on a main body of an apparatus in which a plurality of heating regions are defined, and the temperature deviation of the internal chamber can reduce by providing the amount of heat supplied to each heating region through the control of the plurality of heaters. The main body of the apparatus includes a cylindrical portion in which the powder raw material is accommodated and sidewalls on both sides of the cylindrical portion, and by installing heaters on the cylindrical portion and the sidewalls, respectively, the entire region defining the main body of the apparatus can be evenly heated.
