Embodiment 1

[0052] Vibrating hot film or heat pipe laminar flow grain dryer, its composition includes: a box body 1 with a shock absorbing device, the box body has a material inlet 4 and a material outlet 5, and the box body is equipped with There is a vibrating material bed 6, the upper part of the vibrating material bed is a material chamber 7, the described feed inlet and the discharge port are communicated with the described material chamber, and the bottom of the vibrating material bed is equipped with a heating film 2 or There are heating tubes 3.

[0053] After the heated grain enters the vibrating material bed 6 from the feed port 4, the vibrating material bed will convey the heated grain to the discharge port. The heating body and the vibrating material bed contact to evaporate the water and dry the grain. The gas for heating is heated under the vibrating material bed 6 after it enters from the air inlet.

Embodiment 2

[0055] Embodiment 1 In the vibrating hot film or heat pipe laminar flow grain dryer, the vibrating material bed is 1-15 layers, generally about 10 layers, and the height of the material chamber is less than 20 cm, usually about 15 cm .

Embodiment 3

[0057] In the vibrating hot-film or heat-pipe laminar flow grain dryer described in Embodiment 1 or 2, the vibrating material bed has a stepped turning platform; the vibrating material bed has an inclination angle of 1-15 degrees.

[0058] The length of the vibrating material bed is more than 2 meters. The material bed has a heating film with a far-infrared coating on the downward side, or a far-infrared heating tube.

Abstract

The invention provides an oscillating heating-membrane heating-pipe laminar-flow grain dryer. Traditional tower type drying has great energy consumption during operation; the total power of a drying tower capable of drying 500 T of grains each day is 255 kw, which is totally operating power and is mainly used by a blower fan and an elevator without generation of drying heat. The oscillating heating-membrane heating-pipe laminar-flow grain dryer comprises a box (1) equipped with a damping device; the box is provided with a feed inlet (4) and a discharge outlet (5), an oscillating material bed (6) is arranged in the box, a material chamber (7) is arranged above the oscillating material bed, the feed inlet and the discharge outlet are communicated with the material chamber, and the bottom of the oscillating material bed is provided with a heating membrane (2) or a heating pipe (3). The oscillating heating-membrane heating-pipe laminar-flow grain dryer is used as a grain dryer or a rice airing machine.

Description

[0001] Technical field: [0002] The invention relates to a drying equipment, in particular to a vibration-type drying equipment for grain and bulk materials with an electric heating film or a heating tube. Background technique [0003] Food is a necessity for human life, and all countries attach great importance to food production and reserves. The natural moisture of freshly harvested grain is generally around 17%-32%, and the safe moisture of stored grain is around 13%. Therefore, if it is necessary to store grain safely, it must be stored when the precipitation reaches a safe moisture level. [0004] At present, the common way of grain drying in the world is to use a vertical grain drying tower. The heat source generally comes from coal, fuel oil, rice husk, and straw. The fuel is burned by a hot blast stove to generate hot air. After the grain is put in, the hot air is passed into the drying tower to evaporate the water and reduce the water in the grain.
