The refrigerant module comprises a primary refrigerating module and a secondary refrigerating module, the primary refrigerating module and the secondary refrigerating module each comprising a condenser, an evaporator and a compressor. An air inlet pipe of the air module is connected to a hot side of a heat regenerator, the hot side of the heat regenerator is connected to the evaporators through ventilation pipes, the evaporators are connected to a cold side of the heat regenerator through ventilation pipes, and the cold side of the heat regenerator is connected to one of the condensers through a ventilation pipe.

An environmentally-friendly feed drying and cooling integrated machine, comprising a material drying unit, a material cooling unit and a gas treatment unit, wherein the material drying unit comprises a drying box group (1) and a heating box body module (2); the heating box body module (2) is used for carrying out a drying treatment on materials in the drying box group (1); the material cooling unit is connected to the drying box group (1), receives the materials from the drying box group (1), and carries out a cooling treatment on the materials; two ends of the gas treatment unit are respectively connected to the drying box group (1) and the material cooling unit; the gas treatment unit receives gas discharged from the drying box group (1), carries out a temperature reduction and dehumidification treatment on the gas, and then conveys the gas to the material cooling unit.

The present disclosure provides a method for regulating an inert gas flow in a crystal pulling furnace, a method for preparing monocrystalline silicon, and monocrystalline silicon. The method for regulating an inert gas flow includes introducing the inert gas into a main furnace chamber of the crystal pulling furnace from an auxiliary furnace chamber of the crystal pulling furnace, and regulating a flow direction of the inert gas flow introduced into the auxiliary furnace chamber of the crystal pulling furnace.

Systems and processes for curing a wet coating of a coated substrate are disclosed. The system includes a ventilation system and a curing room configured to receive the coated substrate being displaced along a displacement axis and includes at least an upstream curing section and a downstream curing section. The upstream curing section includes an upstream catalytic infrared heating system for producing an upstream infrared radiation at an upstream radiation intensity to heat and partially cure the wet coating while the coated substrate is being displaced through the upstream curing section. On the other hand, the downstream curing section includes a downstream catalytic infrared heating system for producing a downstream infrared radiation at a downstream radiation intensity, being lower than the upstream radiation intensity, to further cure the wet coating while the coated substrate is being displaced through the downstream curing section for producing a cured coating.

A device for steam disinfecting products includes a treatment chamber. An evaporation pan is arranged in the chamber and heated. A liquid contained in the pan evaporates. A drying air flow is generated by a fan unit and directed onto the evaporation pan via a fan duct. A non-return element is arranged in the fan duct and prevents liquid vapor from getting from the evaporation pan to the fan unit. During an evaporation process, the fan unit is switched off and the fan duct is blocked by a non-return element. During a subsequent drying process, the fan unit is switched on and the non-return element of the fan duct is opened for the drying air flow. During operation of the fan unit, the evaporation pan is heated to a temperature above the specified minimum temperature using a heating device.

A system and method are disclosed for lowering the internal relative humidity inside of a concrete structure by applying a pressurized gas and forcing such pressurized gas into the concrete structure, in turn driving moisture in the pores of the concrete to the exterior of the structure. Pressurized gas is supplied to a network of sealed cavities extending into the face of the concrete structure, ultimately causing the gas to move into the concrete structure through pores and capillaries through the structure, in turn driving moisture in the concrete structure toward the surface. Optionally, a competitive inhibiting agent, such as lithium nitrate, may also be provided to stabilize the concrete structure against future deleterious expansions caused by moisture uptake in the existing ASR gel.

A dryer adapted for use in an asphalt plant. The dryer comprises a drum having an inner wall and a plurality of flights, each of which is disposed on the inner wall of the drum and each of which has a proximal end and a distal end spaced apart from the proximal end. At least one of the plurality of flights comprises a V-shaped notch. A method for drying components of asphalt comprising drying the components of asphalt in the drum of such a dryer.
