Ce Certificate Use to Dry Mushroom Dreg Hollow Paddle Dryer for Sale
Introduction
The hollow shaft of the paddle dryer is densely arranged with
wedge-shaped hollow blades. The heat medium flows through the
blades by the hollow shaft to heat the blades. The material
advances in the vessel at a uniform speed due to the design angle
of the blades and absorbs the heat from the wall of the blade. The
moisture is evaporated and pumped away by the draught fan.
The effective heat transferring area per unit volume is big, heat
medium temperature from -40ºC to 320ºC, can be water vapor, may
also be liquid -type: such as water, oil and so on.
It is Indirect conduction heating, no air take away the heat, high
heating efficiency, the only heating loss just be radiating through
insulation layer. Wedged surface can clear itself, the relate movement between the
material particle and wedged surface will occur scrub, so in operation can maintain a clean heat transfer surfaces.
The shell of paddle dryer is Ω-shape, normally there are 2 to 4 hollow mixing shafts. There is
sealing end plate and cover, can avoid the dust leakage to ensure
the best heat transfer.
Working Principle
steam or thermal oil injected in the rotary shafts and the hollow
blades.Wet sludge is fed into the paddle dryer machine by the screw
feeder or sludge pump, and then is heated indirectly by the heat
medium.New surface area is released continuously while the shafts
rotate so that hot soda ash gets cooled in a high thermal
efficiency.
Dry product is discharged through the discharge valve, while the dusty air is cleaned in the
cyclone dust collector.

Applications
It has been successfully used in the food, chemical, petrochemical, dyes, industrial sludge and other fields. Heat transfer equipment, cooled, stirred solution of the following characteristics makes it possible to complete the unit operations: calcination (low temperature), cooled, dried (solvent recovery), heating (melting), the reaction and sterilization. Stirring blades while the heat transfer surface, so that the heat transfer area per unit effective volume is increased, the processing time is shortened. Wedge-shaped blade heat transfer surface and having a self-cleaning function. Compression - expansion of the material mixture evenly mixing function. Material axially into a "plug flow" movement in the axial zone, material temperature, humidity, mixing gradient is very small.
1) Low energy consumption: As a result of indirect heating, no much air take away the
heating, the outer wall has insulation layer, the heat efficiency
can be up to 90%. For slurry, evaporating 1kg of water just need 1.2kg vapor.
2) cheap investment: it has huge effective heat transfer surface area per unit, reduce treatment time,
let the machine size become small, so It greatly reduces the
construction area and building space.
3) wide range of materials handling: can use different types of media, not only can treat
heat-sensitive materials, but also handle high-temperature
materials. Common medias are: water vapor, thermal oil, hot water,
cooling water and so on.
4) flexible operation method: Can be continuous operation or intermittent operation, can be
applied in many fields.
5) Low environmental pollution: don't use air to dry material, dust material entrainment is rare.
Small solvent evaporation, easy to treat. For contaminated
materials or solvent recovery conditions, closed-loop can be used.
6) Cheap operating costs: Low-speed mixing and reasonable structure, Low wear, low
maintenance costs. For normal operation, just only 1 person / day.
7) Stable operation: Due to the special compression-expansion stirring of the wedge
blades, the material particle contact with the heat transfer
surface enough, it ensure the processing is stable.
