A system for drying grain in a storage bin, having an air injector for injecting external air into the bin interior to displace moist warm air toward an air extractor and the air extractor for extracting moist warm air from the bin interior and directing it outside the bin.

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.

A grain dryer includes a housing having a top end, a bottom end, and a plurality of walls that define an interior space. A grain funnel is positioned along the top end of the main housing, and a grain discharge member is positioned along the bottom end of the housing. One or more HVAC units are provided. Each of the HVAC units including an electrically powered compressor, a fan, a condenser, an expansion valve, and an evaporator that are each connected by a set of refrigerant pipes that are filled with a refrigerant material. Hot air generated by the HVAC units is supplied to a plurality of supply vents positioned along the main housing, and cold air generated by the HVAC units is supplied to a plurality of return vents positioned along the main body at a location adjacent to the discharge member.

MULTIPLE INTERMITTENCE BEEHIVE GRAIN DRYER, refers to a dryer of seeds and other agricultural products that can be a constructive format honeycomb type dryer designed to provide a unprecedented process of multiple intermittence during fast, gentle, non-aggressive drying process of grains and seeds through complete and safe removal of accumulated moisture, being divided into the following stages: drying-resting-drying-resting-drying, and so on until drying is complete. Exposure time to drying air is monitored and allows recirculation of humid air, it also allows batch or continuous drying with a thermally insulated plenum that removes dirty humid air located in the bottom section, without releasing it directly into the environment, with advantages of low production cost, dry grain of much higher quality, better energy efficiency, environmentally friendly and capable of virtually eliminating any accidental risks.

A grain dryer has a grain column configured to receive grain to be dried and ducts extending from a first wall of the grain column to a second wall of the grain column. The grain dryer is configured so that different numbers of the ducts are selectable for handling cooling air used for cooling the grain.
