Abstract

The invention provides a water circulation pre-heating type corncob drier. The water circulation pre-heating type corncob drier is characterized in that a box is partitioned into an upper region and a lower region by a partition plate I; the lower region is partitioned into three parts by partition plates II; a water gas heater is arranged at the bottom of the middle of the box; one end of a heat exchange box above a first conveying device is communicated with the middle of the box, and the other end of the heat exchange box is connected with an induced draft fan which is arranged on the top of the box; two ends of each heat exchange box between upper and lower groove-shaped material channels of the first conveying device are connected with the water gas heater through a circulating water pump; a condensing water pump which is arranged on the top of the box is connected with a straight water pipe which is inserted into each heat exchange box by an annular water pipe; a plurality of conveying devices which are driven by a transmission device to rotate are arranged in the box; a first moulding chain plate and a second moulding chain plate are suspended on a pin shaft of a chain extending inwards at intervals and supported on a guide rail to form a groove-shaped material channel; a material guide groove is formed below the tail end of the channel; a charging hole is formed on the top of the box; and a discharging hole is formed at the bottom of the box. The water circulation pre-heating type corncob drier is good in preheating and drying effect, and reliable in operation.

Description

technical field [0001] The invention provides a water circulation preheating 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 pre...
