Improved water controllable drying machine for mealies alcohol grains production

Abstract

An improved water controllable drying machine for mealies alcohol grains production belongs to drier equipment, wherein a feed port and a dried powder outlet of a tube stream, as well as a steam inlet, a secondary steam outlet and a condensed water outlet of a shell side are arranged on a tube drying machine, and the secondary steam outlet is connected with a fan. The improved water controllable drying machine for mealies alcohol grains production is characterized in that: the temperature monitoring instrument signal which is connected with the shell side of the drying machine is connected with the fan which is connected with the secondary steam outlet of the drying machine, the fan is a variable frequency fan, and the pressure monitoring signal which is connected with the shell side of the drying machine is connected with a steam regulation valve which is connected with the steam inlet of the drying machine. The improved water controllable drying machine controls the shell side temperature and pressure of the drying machine within a certain scope, accordingly, the product water content of the drying machine is effectively and stably controlled, and the product quality is improved, the labor intensity of the personnel is reduced, and the economic benefit of an enterprise is increased.

Description

technical field [0001] The invention belongs to dryer equipment, in particular to an improved dryer capable of automatically controlling the moisture content of output products used in the production of corn ethanol tanks. Background technique [0002] Most companies that produce DDGS from corn distiller's grains have adopted the tubular dryer because of its small footprint, high degree of mechanization, and reusable secondary steam generated during the drying process. The tube side of the dryer is equipped with a feed inlet and a dry powder outlet, and the shell side is equipped with a steam inlet, a secondary steam outlet and a condensed water outlet, and the secondary steam outlet is connected to the fan. The wet grains produced by the centrifuge, part of the dry powder, and the evaporated thick slurry are fully mixed by the mixer and then enter the dryer for drying operation. After reaching a certain moisture content, the dry powder is discharged, and a part of the dry p...

AI Technical Summary

Problems solved by technology

The moisture control of the finished product of the dryer is entirely based on experience (hand feeling) and post-testing of the finished product. There is no data and rational operation methods as support. The product quality is determined by the experience and skills of the employees. Therefore, the moisture control of the finished product has always been It is more difficult for various enterprises to grasp. Even skilled workers with certain operating experience are not completely able to control the moisture within the target. In most cases, it is just an average value. In bulk products, the moisture content is just an average value. value, there are both products with lower than standard moisture and products with higher than standard moisture. Within a certain period of time, mildew and other phenomena will occur
