Abstract

The invention relates to a double heat type vibration laminar-flow grain dryer. Currently, a vertical grain drying tower is commonly used for grain drying in the world. The heat source of the vertical grain drying tower generally is coal, fuel oil, burning rice husks or straws; a burning material combusts in a hot-blast stove and generates hot wind which is introduced into grain piles to dry grains; and such a drying manner has considerable disadvantages. The double heat type vibration laminar-flow grain dryer provided by the invention comprises a box (1) equipped with a damping device; the box is provided with an air inlet (2), an air outlet (3), a feed inlet (4) and a discharge outlet (5), a vibrating material bed (6) is arranged in the box, a material chamber is arranged above the vibrating material bed, and the feed inlet and the discharge outlet are communicated with the material chamber. The double heat type vibration laminar-flow grain dryer is used as a grain dryer or a rice airing machine.

Description

technical field [0001] The invention relates to drying equipment for grain and bulk materials, in particular to a dual-heat vibrating laminar flow grain dryer. Background technique [0002] Food is a necessity for human life, and all countries attach great importance to food production and reserves. The moisture content of freshly harvested grain is generally around 17%-32%, and the safe moisture content of stored grain is around 14%. Therefore, if it is necessary to store grain safely, it must be stored with precipitation to reach a safe moisture content. 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, which is passed into the grain pile to dry the grain. This drying method has many disadvantages: [0003] The flue gas after fuel combustion is generally about 150°C, and is directly dischar...
