Distilled grain airflow dryer

Abstract

The invention discloses a distilled grain airflow dryer. A drying chamber of the distilled grain airflow dryer is an oblique long container, the cross section of the drying chamber is in a sector shape, the high end of the drying chamber is sealed, and the upper portion of the low end of the drying chamber communicates with an air inlet pipe of a cyclone discharger. Multiple funnels are arranged on the lower portion of the drying chamber and are connected with multiple air blowing openings of an air heater. The air blowing opening of the first air heater on the lower portion of the high end ofthe drying chamber is larger and is connected with a t-branch pipe, and a spiral conveyor is arranged in a transverse pipe of the t-branch pipe. A finned air heater air inlet pipe is wrapped in a gasoutlet pipe of the cyclone discharger, a liquid collection hopper is arranged on the lower portion of the gas outlet pipe of the cyclone discharger, and a liquid discharging valve is arranged below the liquid collection hopper. A gas outlet is formed on the lower portion of the gas outlet pipe of the cyclone discharger, and an advertising gas pipe is arranged on the gas outlet and supplies discharged waste gas to the two sides of a highway to be used as white wine smell advertising. According to the dryer, the drying time of distilled grain in the drying chamber is long, the dryer is an airflow dryer capable of evenly drying large particle containing distilled grain, and the waste gas can be recycled.

Description

technical field [0001] The invention relates to a drying machine, in particular to a distiller's grain airflow dryer. Background technique [0002] Distiller's grains are the dregs left over from the production of liquor in liquor factories. It is a high-quality livestock feed. Because it contains about 60% water, it is easy to deteriorate after a long period of time. After drying, it can be stored for 3 years without deterioration. [0003] At present, the vertical drying tower type airflow dryer is generally used for drying distiller's grains. The material is conveyed by a screw conveyor and heated by a hot air blower. Airflow drying is carried out in the vertical drying tower, and the material is discharged by a cyclone unloader. The particle size of the wet distiller's grains entering the drying tower is uneven, and the drying time is short. The drying tower with a height of 10-15 meters cannot evenly dry large grains of distiller's grains at a time, so the vertical airf...

[0003] At present, the vertical drying tower type airflow dryer is generally used for drying distiller's grains. The material is conveyed by a screw conveyor and heated by a hot air blower. Airflow drying is carried out in the vertical drying tower, and the material is discharged by a cyclone unloader. The particle size of the wet distiller's grains entering the drying tower is uneven, and the drying time is short. The drying tower with a height of 10-15 meters cannot evenly dry large grains of distiller's grains at a time, so the vertical airflow drying tower The dried distiller's grains are unevenly dried, and the waste gas discharged from it has high temperature and high humidity, and contains alcohol gas and wine aroma, which is not recycled.
