Papua New Guinea LDG single cone vacuum spiral belt dryer

The machine is equipped with a heating sleeve on the heating funnel, and the heat source uses hot water, heat transfer oil, and low-pressure steam to keep the inner wall of the funnel at a certain temperature. The frequency conversion motor rotates the single spiral mixer through the parallel spiral gear reducer, so that the material rotates along the conical cylinder and pulls from bottom to top. After the material reaches the highest point, it automatically flows to the vortex center and returns to the bottom of the conical cylinder under the action of gravity and inertia. The whole process makes the material forcibly heated in the conical cylinder, with relative convection and mixing. The heat diffuses in the material to make the material move irregularly in all directions, the high-frequency heat transfer and exchange of the material with the single screw belt and the surface of the cylinder wall are completed, and the effect of heating and drying is achieved in a short time. In order to make the material internal water evaporation, under the action of the vacuum pump, water vapor from the vacuum pump, such as the need to recover the liquid can be added condenser, recovery liquid storage tank recovery. After the drying is completed, open the lower discharge valve to discharge the material.

Product Description

Working principle

The machine is equipped with a heating sleeve on the heating funnel, and the heat source uses hot water, heat transfer oil, and low-pressure steam to keep the inner wall of the funnel at a certain temperature. The frequency conversion motor rotates the single spiral mixer through the parallel spiral gear reducer, so that the material rotates along the conical cylinder and pulls from bottom to top. After the material reaches the highest point, it automatically flows to the vortex center and returns to the bottom of the conical cylinder under the action of gravity and inertia. The whole process makes the material forcibly heated in the conical cylinder, with relative convection and mixing. The heat diffuses in the material to make the material move irregularly in all directions, the high-frequency heat transfer and exchange of the material with the single screw belt and the surface of the cylinder wall are completed, and the effect of heating and drying is achieved in a short time. In order to make the material internal water evaporation, under the action of the vacuum pump, water vapor from the vacuum pump, such as the need to recover the liquid can be added condenser, recovery liquid storage tank recovery. After the drying is completed, open the lower discharge valve to discharge the material.

 

Features and Uses

The machine is also called spiral vacuum dryer, is a vertical dryer, small footprint, high drying efficiency, cone screw is the main component of the machine; and is a set of drying, crushing, mixing as one of the high-efficiency multi-function closed vertical vacuum drying equipment. The drying efficiency is higher than the "double cone rotary vacuum dryer" of the same specification ". It is mainly used for powder drying in pharmaceutical, chemical, pesticide, food and other industries. It is a very cost-effective and practical multifunctional equipment for users.
