Paddle dryer (cooler)
 

  (1).Introduction

  Paddle dryer (cooler) is a compact, indirect-heat equipment with high thermal efficiency. By mechanical structure, it is made up of top cover, rotating shaft, trough, dryer frame and driving unit. Paddle shaft is key part of the dryer, which consists of hollow shaft(s) and hollow blade with special flow channels. The trough is inclined to horizontal. Wet cake is fed into the inlet nozzle and transported to the outlet nozzle due to the rotation of shaft and gravity. Dried product is transported to downstream process after overflow the dam. The thermal is transferred to (or from) the material via hollow blade, hollow shaft and jacket to implement the purpose of heating or cooling.

  Paddle dryer (cooler) is mainly used in process of drying, reacting, cooling, crystallizing, evaporating, sterilizing, low temperature roasting etc. for non heat-sensitive organic and inorganic products and heat sensitive products in vacuum condition. It can also be used for combined multi-application.

  By heating medium, paddle dryer can be classified as steam type (saturated steam or superheated steam) and liquid type (water or oil, hot or cool). By operation method, it can be categorized into continuous and batch type. By the number of paddle shaft, it can be categorized into single shaft, twin-shaft and quad-shaft. By operating pressure, paddle dryer can be categorized into vacuum type, atmospheric type and pressurized type.

  Usually two paddle shafts rotate in opposite directions as a coupled rotors. Specially designed paddles secures sufficient contact between the blade surface and the material. Owing to the wedged shaping of blade, material can be pressed and released alternatively in the axial direction, which makes paddle blades self-cleaning. Relative shear force between blades and material keeps blades clean for better heat and mass transfer.

  (2).Features

  Compact structure with large heat exchange surface and small installation space

  Even distribution, high thermal efficiency, good drying effect

  No adhere with self-cleaning wedge-shaped paddles

  Low energy consumption and low operation cost Low dust and material loss

  Indirect-heating (cooling), no contamination to product.

  Simple control interface, flexile and reliable operation

  Gas-tight for toxic and odorous products

  Multifunction for different process

  (2).Specifications

  By heat-exchange area, there are specifications from 2 to 350m2, with shaft speed 5 to 20rpm. Hollow blades can be wedged or disk type. Customized design is available.

  (4).Application
