Waste heat recovering ear-corn drying machine

Abstract

The invention provides a waste heat recovering ear-corn drying machine, which is characterized in that the chamber of the drying machine is divided into an upper area and a lower area by a partition I; the lower area is divided into three parts by partitions II; the bottom of the middle chamber is provided with an air heater with a blower; a plurality of heat exchange boxes are arranged in the upper area and are communicated with one another by annular air pipes; the heat exchange boxes on the lower part are communicated with the middle of the lower area of the chamber; the heat exchange boxes on the upper part are connected with an induced draft fan mounted at the top of the chamber; a water pump at the top of the chamber is connected with a straight pipe inserted in each heat exchange box by a water pipe which is shaped like a Chinese character 'YUE'; a plurality of conveying devices running under the driving of a driving device are arranged in the chamber; molding link plates of I and II types are hung on a pin shaft extending out of the inner side of a conveying chain at intervals and are arrayed and supported on a guide rail to form a trough material channel; a guide chute is arranged below the tail end of the channel; and a feed inlet and a discharge port are formed at the top and the bottom of the chamber respectively. The waste heat recovering ear-corn drying machine is large in moisture reducing range, good in preheating effect and reliable in working.

Description

technical field [0001] The invention provides a waste heat recovery type corn cob dryer, which is mainly used for dehydrating and drying wet corn cobs with high moisture content just after picking from corn stalks. Background technique [0002] China is a large agricultural country, especially in Shandong, Henan and Northeast China, which are the major food producing areas such as corn. With the development of the breeding industry and the increase in the demand for feed, the planting area of ​​corn has gradually expanded, and the output has increased year by year. The harvest moisture of corn is generally 25%-35%. If there is no good corn drying equipment, it will cause a lot of loss due to excessive moisture and mold. Therefore, farmers' demand for corn dryers is becoming more and more urgent. It is of great significance to develop corn dryers with high precipitation, good drying uniformity and high quality to promote the development of corn industry. [0003] At present...

Problems solved by technology

However, when the hot and dry air of this machine is dried from bottom to top to the wet ear of corn in the trough-shaped material channel of the uppermost conveying device, the moisture content of the air is relatively high and the temperature is relatively low, so although it can The ear of corn is preheated, but due to the high moisture content of the air, it is sometimes even possible to humidify the ear of corn even if its moisture content increases
