Cooling discharge type corncob drying machine

Abstract

The invention provides a cooling discharge type corncob drying machine. The cooling discharge type corncob drying machine is characterized in that the inner part of a box is divided into an upper region and a lower region by a separator plate I; the lower region is divided into three parts by a separator plate II; the separator plate I and separator plates III and IV located at the lower part of the box form a cooling region; a water heater is arranged at the bottom of the middle box; the cooling region is connected with the air inlet of the water heater by a blower; the air outlet of the water heater is connected with the middle part of the box; one end of each heat exchange box at the uppermost part in the box is communicated with the middle part of the box, and the other end of the heat exchange box is connected with an induced draft fan; two ends of each heat exchange box in the lower place are connected with the water heater by a circulating water pump; a condensate water pump is connected with straight water pipes in each heat exchange box by an annular water pipe; a plurality of conveying devices which are driven by a transmission device are arranged in the box; each forming chain plate is supported on a guide rail to form a groove-shaped material channel; a guide chute is arranged under the tail end of the channel; a feed port is formed in the top part of the box; and a discharge port is formed in the bottom of the box. The cooling discharge type corncob drying machine is good in drying effect and low in energy consumption, and corncobs can be packaged directly after being dried by the drying machine.

Description

technical field [0001] The invention provides a cooling and discharging 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 pre...
