Net band transmission type vacuum continuous drying device and net band transmission type drying device

Abstract

The invention discloses a mash belt transfer type vacuum continuous drying apparatus and a mash belt transfer type drying apparatus, which comprises a cylindrical barrel, a spherical cap-shape end cover, and an evacuating pipe, wherein the cylindrical barrel is horizontally arranged, a square silo is sleeved in the inner cavity of the cylindrical barrel, a certain number of floors of flat-type water pipes are mounted between two body walls of the square silo, and the flat-type water pipe which is on the highest layer is communicated with a water inlet pipe, and the flat-type water pipe which is on the lowest layer is communicated with a water outlet pipe, the intermediate flat-type water pipes are communicated end to end, and water glide path is led to take zigzag-shape arch type. A certain number of turn rollers which are regularly arrayed are mounted between the two body walls of the square silo, the turn rollers which are connected with a power mechanism are sleeved with ring-shaped mash belt, which leads materials on surface of the upper layer of the flat-type water pipe to convey to the surface of the lower layer of the flat-type water pipe, two lateral side of adjacent flat-type water pipes are alternatively arrayed respectively, and a feed inlet and a feed outlet are respectively arranged on the two sides of the adjacent flat-type water pipes which penetrates through the cylindrical barrel and the square silo.

Description

1. Technical field: [0001] The invention relates to a drying device, in particular to a mesh-belt-driven vacuum continuous drying device and a mesh-belt-driven drying device. 2. Background technology: [0002] my country is a large agricultural country, and the output of crops is huge. If they are not stored well, they will deteriorate. Therefore, it is necessary to reduce their moisture content before storage. At present, the traditional drying method mainly adopts hot air drying equipment, which makes the hot air pass through the crop particles under normal pressure to evaporate its moisture. The drying methods are usually cross flow, mixed flow and forward (counter) flow, but this drying method , it is easy to damage the inherent quality of crops. Taking dry corn as an example, the temperature of hot air is generally 120-160°C, while the natural temperature in the dry season in Northeast China is -5--30°C. Due to the huge temperature difference, the corn is dry During th...

Problems solved by technology

The dryer adopts the structural form of upper and lower multi-layer conveying mesh belts. Its drying process is long and it uses flowing hot air to dry, but its thermal efficiency is not high. In addition, there are certain defects: each layer of conveying mechanism is set separately, resulting in space The size is large, the structure is complex, and the cost is high; in addition, the use of hot air drying is prone to defects such as cracks on the surface of the grain and insufficient dryness of the inner core
