Energy-saving dryer and drying method thereof

Abstract

The invention discloses an energy-saving dryer and a drying method thereof. The energy-saving dryer mainly comprises a dryer main body, a transmission system and a heat energy exchanging system, wherein the dryer main body comprises a front part area 20 and a back part area 21 and the tail end of the front part area 20 is connected with the front end of the back part area 21; an emptying area 22 is arranged on the front end of the front part area 20 and a material receiving area 23 is arranged on the tail end of the back part area 21; and the transmission system is equipped between the front part area and the back part area and is used for driving the whole dryer. The heat energy exchanging system which is arranged on one side of the dryer comprises a heat exchanger, a draught fan and an air channel; and a movable door is arranged on the other side of the dryer. The invention provides the novel energy-saving dryer which has the advantages of simple structure, high efficiency and low consumption, stable production and convenience for repairing and clearing and also provides the drying method of the energy-saving dryer.

Description

technical field [0001] The invention relates to the field of grain processing machinery, in particular to an energy-saving dryer and a drying method. Background technique [0002] Rice noodles (bars) are a kind of traditional food in my country. The bars are as thin as silk, white as silver, good in quality and delicious, and resistant to storage, easy to carry, rich in toughness, and suitable for boiling, frying and frying. What rice flour adopts in most areas is still the simple and crude equipment of handicraft workshop type production and the drying equipment that the traditional sun and wind blow backward. The new domestic rice noodle dryer is just a chain box type circulation dryer. Multiple heat exchangers are installed on the top of the dryer, which not only causes waste of heat energy, but also makes it difficult to control the humidity of the rice noodle during the drying process. Being in high temperature makes the rice noodles crispy and broken, and there is no ...

The new domestic rice noodle dryer is just a chain box type circulation dryer. Multiple heat exchangers are installed on the top of the dryer, which not only causes waste of heat energy, but also makes it difficult to control the humidity of the rice noodle during the drying process. The high temperature makes the rice noodles crispy and broken, and there is no cooling equipment at the outlet of the rice noodles drying, so the rice noodles have the defect of a lot of broken powder when picking up
