Chicken manure hollow paddle dryer for organic fertilizer

Description of Hollow Paddle Dryer:

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 cabinet of hollow paddle dryer 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 of hollow paddle dryer:

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: Hollow paddle dryer 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: Hollow paddle dryer 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: Hollow paddle dryer can be continuous operation or intermittent operation, can be applied in many fields.
5) Low environmental pollution:  Hollow paddle dryer does not use air to dry material, dust material entertainment 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.
