Pellet drying machine

Abstract

The invention provides a pellet drying machine. The pellet drying machine comprises a shell, a double-cone cylinder in the shell, a speed adjustment motor arranged at the rear end of the cylinder, and an electric appliance controller, and further comprises an electromagnetic valve, an induced draft fan, a heater, a temperature-humidity sensor, a dust removal system and a moisture removal system, wherein the heater, the temperature-humidity sensor, the dust removal system and the moisture removal system are located in the shell, the side of the shell is provided with an air draft channel tangent to an outer circle of the cylinder, the induced draft fan is connected with the rear end of the double-cone cylinder through the electromagnetic valve, and the inner wall of the cylinder is provided with discontinuous double layers of blades which are spirally distributed in two directions. The pellet drying machine has the advantages that pallet drying efficiency can be effectively improved, the thermal energy utilization rate is high, and pellets are heated uniformly and sufficiently dried.

Description

technical field [0001] The invention belongs to the field of pharmaceutical processing machinery, in particular to a pellet dryer. Background technique [0002] Pellet drying is an important step in the preparation of pelleted pharmaceuticals. Traditional pharmaceutical drying equipment includes drying ovens or drum dryers. The effective drying area of ​​the drying ovens is relatively small. Although the general drum dryers increase the size of the pellets However, the single-layer blades in the cylinder will cause the pellets to accumulate on one side of the blades during the rotation of the cylinder, so that the pellets to be dried cannot be fully dried; on the other hand, the current The air outlet setting of the state-of-the-art drum dryer causes the airflow in the cylinder to be disordered, and part of the hot air is even directly drawn out. The utilization rate of heat energy is not high, and the drying effect on pellet medicine is not good. Contents of the invention...

Problems solved by technology

[0002] Pellet drying is an important step in the preparation of pelleted drugs. Traditional drug drying equipment includes drying ovens or drum dryers. The effective drying area of ​​the drying ovens is relatively small. Although the general-purpose drum dryers increase the size of the drug pellets However, the single-layer blades in the cylinder will cause the pellets to accumulate on one side of the blades during the rotation of the cylinder, so that the pellets to be dried cannot be fully dried; on the other hand, the current The air outlet setting of the state-of-the-art drum dryer causes the airflow in the cylinder to be disordered, and part of the hot air is even directly drawn out. The utilization rate of heat energy is not high, and the drying effect on pellet medicine is not good.
