Mixed tunnel dryer

Abstract

The invention discloses a mixed tunnel dryer. The mixed tunnel dryer comprises a dryer body. The dryer body is characterized in that a feed inlet is formed in one side of the dryer body, the feed inlet is connected to a primary drying tunnel, electric guide rails are arranged on bottom faces of the primary drying tunnel and a secondary drying tunnel, dumpers are arranged on the electric guide rails, rollers are mounted on the bottom ends of the dumpers, an orthokinetic hot wind delivery pipe is arranged above the primary drying tunnel, the tail end of the primary drying tunnel is connected to the front end of the second drying tunnel, a reverse cold wind delivery pipe is arranged above the secondary drying tunnel, a discharge port is formed in the tail end of the secondary drying tunnel, and a central exhaust port is formed above the connection of the primary drying tunnel and the secondary drying tunnel. In this way, water can be evaporated by orthokinetic fair current hot wind first, and then residual heat and moisture in air by fair current cold wind dehumidification, so that a drying level with a higher efficiency is achieved.

Description

technical field [0001] The invention relates to the field of dryers, in particular to a hybrid tunnel dryer. Background technique [0002] The drying machine is to evaporate the water from the target material. The target material is deteriorated due to carrying a large amount of water. The drying objects are various, from building materials, coal to grains and fruits. There are many drying principles of the dryer, and the common one is hot air. , infrared, microwave and vacuum drying, the shape has box type, tower type and tunnel shape, etc. Most hot air dryers use downstream drying technology, but there is a lack of cooling system after drying, and a large amount of material is often carried around the dried material Water vapor, moisture surrounds the outside of the material. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a hybrid tunnel dryer, which can first use the same direction and downstream hot ai...
