High quality Chinese Dryer manufacture Textile sludge Hollow paddle drying Machine
Product Description:
Dual counter-rotating shafts with unique intermeshing hollow wedge-shaped paddles produce intimate mixing, optimize heat transfer, and provide a self-cleaning feature. A large heat transfer area to volume ratio is achieved by the use of hollow paddles and a jacketed vessel, through which the heating medium flows. The result is an efficient, compact machine with less space requirements and lower installation cost.
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.

Petrochemical industry: polyolefin powder, polycarbonate resin, high and low-density polyethylene, linear low-density polyethylene, polyacetal granules, nylon 6, nylon 66, nylon 12, acetate, polyphenylene sulfide, propylene base resin, polypropylene, engineering plastics, polyvinyl chloride, polyvinyl alcohol, polystyrene, polyester, polyoxymethylene, styrene-acrylonitrile copolymerization, ethylene-propylene copolymerization.
Environmental protection industry: sludge, electroplating sewage
sludge, boiler soot, sugar factory waste residue, pharmaceutical
factory waste residue, MSG factory waste residue, coal ash.
Feed industry: soy sauce residue, bone-based feed, distiller's
grains, food scraps, apple pomace, orange peel, soybean meal,
chicken bone feed, fish meal, feed additives, bio-sludge.
Food industry: starch, cocoa beans, corn kernels, salt, modified
starch, medicines.
Chemical industry: soda ash, NPK compound fertilizer, kaolin,
bentonite, white carbon black, carbon black, phosphogypsum, calcium
sulfate, calcium nitrate, magnesium carbonate, sodium cyanide,
oxidized sodium fluoride, aluminum hydroxide, barium sulfate,
calcium carbonate, molecular sieves, dyes, saponins.
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.
