Steamed off-line is the present domestic and foreign each big, medium and small - the more commonly used a leaching meal desolventizing drying equipment.This equipment has the desolventizing effect is good, large capacity, low power consumption, steam consumption is small, simple manufacturing, save material, etc.
1.steamed off-line mainly consists of pot body, delaminating, desolventizing layer, drying, mixing device transmission mechanism and automatic blanking door institutions, by direct and indirect steam steam jacket heat distillation of wet meal desolventizing drying.
2.there is a steam pre delaminating interlayer heating plate, wet meal to take off a layer, by pre delaminating space and sufficient heat and directly by steam to take off the part of the solvent.
3.steaming layer shell with steam jacket, chassis open several holes have a diameter of 2.5 mm, through the small hole injection pressure is 0.05-0.1 Mpa steam directly, to heat the steam to take off
the wet meal solvent.Steamed delaminating pot body height is 2.3-2.5 m, the height of the wet pulp material layer control in 0.8-1.8 m, due to the material layer is higher, the direct steam injection from the chassis holes through material layer, can contact with the material thoroughly, the use of steam is more sufficient, therefore desolventizing effect is ideal. 4.drying layer height is small, only 700 mm, the bottom has steam jacket, indirectly by pressure of 0.5 Mpa steam for heating drying wet meal. 5.stirring device by in steamed up and down in the drying machine is a vertical axis and the seven layers of different forms of mixing blade.In advance to take off the layer and dry layer at the bottom of the layer of arms mixing blade, the knife is used to beat the loose layer makes the material evenly.Steaming off layer is equipped with three mixing blade, is the top arms mixing blade, its role is to make pulp evenly dispersed in the process of the delaminating down on the material;Middle is equipped with a single arm stir knife, lower arms with mixing blade, the two layers of the knife is used for mixing material layer, prevent short circuit, direct steam in order to improve the desolventizing effect, and make the blanking evenly.
The actuator adopts the bottom drive.Stirring shaft with reducer connected by coupling, and then with a motor drive.
6.automatic blanking mechanism: desolventizing layer of blanking mechanism for this layer to control this, after achieving material layer height can make the door open.Drying layer of blanking mechanism for the control of the upper and lower in setting after drying layer material level height, open the bottom discharging stand door, which can automatic control on a layer of material door closed.Exsolution and dry layers of top packing indexes were set up, to remind the operator timely and correctly open closed discharging stand door, the size of the operation is very simple.
7, solvent steam by exsolution machine at the top of the pipe by wet meal precipitator have been separated at the end of the meal after entering the condenser recovered solvents.To prevent drying layer endotracheal trace solvent gas emissions, should be within the export of other devices connected to the condenser (such as hot water circulating tank condenser).Other second drying floor pull port can be directly connected to the outdoor, discharge water vapor.
