Single cone dryer with single spiral stirrer

Abstract

The invention discloses a single cone dryer with a single spiral stirrer, which comprises a conical shell, a stirrer, a top cover, a rod-like collector and a vacuum pump, wherein the stirrer is a single spiral stirrer, is vertically arranged in the conical shell and comprises a stirring main shaft, stirring blades and a supporting member; the spiral stirring blades are fixed on the stirring main shaft, the stirring blades surround the stirring main shaft and spirally extend to the lower part of the stirring main shaft from the upper part of the stirring main at intervals; and the radius of spin of the stirring blades gradually reduces from top down. The rod-like collector comprises a vacuumizing tube, wherein one end of the vacuumizing tube is provided with a filter hood; the filter hook is connected with a gas blowback tube; and the gas blowback tube is provided with a manual ball valve. The single cone dryer of the invention can reduce drying time, make the quality of the product uniform and blocking-free, improves drying efficiency and optimizing drying effect; and the filtering area of the collector is large, the efficiency is high, the detachment and cleaning are convenient, and the degree of risk to the materials is lowered.

Description

technical field [0001] The invention relates to a drying device, in particular to a single-cone dryer with a single-screw agitator. Background technique [0002] The dryer is mainly used for the purification and drying of medicines. At present, a vacuum rotary dryer is usually used, its two ends are conical, and the body is cylindrical, also known as a double-cone dryer. The middle part of the body of the double-cone dryer is provided with a hollow suspension shaft to provide rotating support and related pipeline laying. The double-cone dryer is rotated to heat and dry the medicines and other products that need to be dried in the double-cone dryer. [0003] However, due to the huge volume of the double-cone dryer and its inherent drying method, the drying efficiency is low and the effect is poor during use, and the trap of the double-cone dryer is in the container, so it is inconvenient to disassemble and clean after each use , and in direct contact with the material, the...

Problems solved by technology

[0003] However, due to the huge volume of the double-cone dryer and its inherent drying method, its drying efficiency is low and the effect is poor during use, and the trap of the double-cone dryer is in the container, so it is inconvenient to disassemble and clean after each use , and in direct contact with the material, there is a certain risk for the material with high requirements for aseptic level. In addition, the trap also has the problems of small filtration area and low efficiency
