Function and performance characteristics:
DTC desolventizer is used for desolventizing and drying oil meals in extraction plant. This equipment uses indirect steam together with direct steam to desolventize, and perform indirect drying through drying layer, finally cooling and lower the oil meals temperature through drum room temperature air. There is no air lock device at the discharge hole of the desolventizing layer, and with stepless speed regulating saving steam
This equipment has characteristics of simple structure, stable working performance, reliable material level control, thorough desolventizing function, adjustable drying and dehydration function, etc. DTC desolventizer is an ideal desolventizing machine of extraction production line. It is widely used in all kinds of oils & fats industries.
Operating principle and main structure:
After the materials enters into the pre-desolventizing disc of DTC desolventizer through filling screw feeder, perform indirect heating through pre-desolventizing layer, part of the solvent and water have been evaporated. And then the materials fall onto the disc surface through pre-desolventizing layer discharge hole, the disc is further indirect heated, and the solvent and water evaporate once again, most of the solvent in meals vaporized. And then the materials enter into direct steam layer through disc discharge hole, and the materials through high temperature lavation of direct steam, and the solvent in meals once again be vaporized and brought out, and the desolventizing effect of materials is more thorougher. The materials after desolventized enter into drying layer through air lock, under combined action of the bottom interlayer and side steam drum, further vaporize the water in meals and bring it out to achieve the drying purpose.
The materials layer thickness controlled by the automatic material gate, when the materials layer is thinner, the automatic materials gate is closed. As the materials thickening, under the combined action of material layer`s buoyancy and rimer, the material pendulum of automatic material gate is supported, turn on the material gate through the outer tension rod. This layer of materials gradually fall off, the materials layer is thick and the material gate opening is big. While the materials layer is thinner, and the material gate opening is small, so that control each layer of material level within a certain scope of thickness of the process requirements, thus achieve the automatic control of the material level.
The room temperature strong wind provided by the air blower direct enters the cooling layer through the bottom interlayer orifice, cooling the materials after drying. The cooling materials conveyed to the meals storehouse by the meal flight conveyer.
The equipment mainly consists of shell assembly, pre-desolventizing disc, disc, air lock, material gate device, main shaft, rimer, coupling, leg, reducer, motor, blower, cyclone collector, etc.
