The present invention proposes a drying tower with grain flow in parallel and sinuous in combination with reverse and radial crossed air flows in form of Z oblique for the implementation in the drying of grains, seeds, fodder, and fruit. Therefore, the grains are firstly submitted to a first stage of parallel grains flow and reverse crossed air flow in order to standardize the different degrees of humidity of the grains and of their impurities. In a second moment, these grains are submitted to a sinuous grains flow and radial air flow in the form of oblique Z. Such implementation in drying processes of grains upgrades substantially the drying time and the energy spent for such process, generating in this way profit for the food industries.

A device for drying grain includes a housing having an inlet port and an outlet port, a first passageway, a second passageway, a grain flow housing, a filter across the grain flow housing, a recovery column, an air supply, a recycle column, a filter cleaner in the recovery column, and a conveyor for moving the filter cleaner along the filter. The air supply pulls an air flow into the housing through the inlet port as a grain flow pours through the grain flow housing. The air flow passes through the grain flow in a first pass air flow from the passageways to dry the grain. The first pass air flow passes through the filter to remove particles, and a portion of that filtered first pass air flow is recycled back with the filter cleaner to dislodge particles clogging the filter. The other portion is vented through the outlet port.

There is provided a multi-module counterflow drying apparatus (100) for drying material, the apparatus (100) comprising: a material inlet (102); a material outlet (104); a heat inlet (108) for inputting heat to the apparatus such that the heat traverses the apparatus in the opposite direction than the material; and a plurality of mutually interchangeable modules (110) stacked on top of each other, wherein the material is configured to move in the apparatus from one module to another such that the movement direction of the material in a given module is opposite to the movement direction of the material in a module above or below, wherein each module (110) comprises: movable paddles (210) configured to discontinuously move the material forward in the module (110).

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 method and an apparatus are disclosed for processing plastics, in which the material in incoherent solid state is dehumidified in a hopper and is then melted in an extruder, after which the molten material is used in a moulding device for moulding by injection and/or by blow moulding and/or compression, and in which a set point pressure value of the molten material is set on the basis of a measured residual humidity value of the dehumidified incoherent solid material, so as to decrease the pressure value by a preset variation value if the measured residual humidity value is lower than a reference value and to increase the pressure value by a preset variation value if the measured residual humidity value is higher than said reference value.
