Exporting Small Scale Electric Sludge Slurry Rotary Ss304 316 Drying Machine
Product Description:
paddle dryer is a compact machine. That is because it has many square meters of heat exchanging surface relative to the volume. Two hollow shafts with hollow paddles turn in opposite directions in the horizontal trough. The trough has an ω- (omega) shape that follows the contours of the paddles.
Moving parts are crucial for the system. They have been expertly designed. Excellent heat transfer is ensured when the product is refreshed regularly and remains in good contact with the heat exchanging surface. The paddles of the paddle dryer play a large role in creating these optimal conditions. The uniquely shaped paddle has a self-cleaning capacity. The wedge-shaped paddle produces shear forces on the paddle surface and this keeps the paddle clean and contributes to a higher heat transfer.
Working Principle
The paddle dryer is compact in structure and mainly consists of a sandwich casing, a central shaft with staggered blades, inlet and outlet joints, drive mechanisms, control boxes, and other components.
The cylinder is a jacket structure in which hot steam circulates inside. During operation, water vapor is introduced into the jacket, hollow shaft, and blade to provide the heat required for drying; a very small amount of air is introduced into the dryer and used as a carrier for the steam (or organic steam) that evaporates during drying; the material enters the machine from the feed port, and is conveyed by the hollow blade to the discharge port for discharging. The material is heated and evaporated by the hollow blade and the jacket during the conveying process to be dried. The heat transfer surface of the wedge blade has a self-cleaning function. The relative motion between the particles and the wedge surface produces a washing effect that washes away the adhering material on the surface of the blade, which allows the material to have a long residence time and a high fill factor.

Features
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.
