Product Description

Main features

1. Thermal drying of various kinds of sludge/biosolids under vacuum condition;
2. Heating area: 10-300 M2
3. Evaporation capacity: 50-2000 kg/h
4. Working type: Batch or continuous
5. Heat source: 65-80 ℃ hot water from heat pump

Working Principle

PZG series vacuum paddle dryer is indirect contact dryer under high vacuum condition to considerably reduce water boiling point. The dryer consists of a jacketed cylindrical drying chamber and a rotor fitted with hollow discs. Hot water from heat pump flows both inside the jacket and hollow discs to form heat transfer surface.

Wet material is fed into the dryer via rotary valve or sludge pump. Due to the rotation of rotor, wet material is mixed and pushed forward by the agitator paddles attached to the disc peripheries. Fixed scraper bars are installed between the disc to prevent wet material from sticking to the discs. With regular mixing, movement and heat transfer between wet material and heated surface, moisture evaporates rapidly. When wet material reaches the opposite end of the dryer, it is dried and discharged via rotary valve. The evaporated moisture is sucked out by vacuum pump and recovered by tubular condenser.

Technical advantages

Our Heat Pump Vacuum Paddle Dryer has been increasingly used for drying sewage sludge, industrial sludge, organic waste, fishmeal, feather meal etc, due to the following overwhelming advantages:

1. Low temperature drying: Vacuum degree can reach as low as 1000 pa. Water boiling point under such low vacuum is only about 45 ℃. The evaporation rate can still reach 6-8 kg water/hr/M2 when use 80 ℃ hot water for drying.

2. Super low energy consumption:The average heat consumption to evaporate 1 kg water is about 600 kcal because of high vacuum, large heating surface and little heat loss. Waste heat in the vapor can be recycled by the heat pump to further reduce energy consumption.

3. Almost zero-emission:The drying process conducts in a completely sealed system and the evaporated moisture is trapped by air-liquid separator and tubular condenser to prevent emission.

4. Batch or continuous operation:Our vacuum paddle dryer can work both in batch or continuous operation to satisfy different working conditions.

Tubular heating jacket

1) Working pressure as high as 10 bars
2) 80 mm mineral insulation to prevent hot loss
3) Full-length vapor dome reduces carry-over and separates solids from the evaporated water vapor.
4) Removable covers provide easy inspection, cleaning and adjustment

Hollow disc

1) Considerably increase heating surface
2) Much less welding area than other types of paddles
3) Self-cleaning disc surface considerably enhances heat transfer

4) Agitator paddles welded on disc peripheries with different angle can perfectly mix, move and crush wet material
5) Scraper bars installed between the discs prevent wet material from sticking to the discs

FAQ

Q: What information should be provided in order to get a proposal or quotation?

A: Our rotary vacuum paddle dryer is specially designed for each customer according to specific wet material, capacity, drying temperature and heat mediums. Before we can work out a detailed proposal, we have to know the following information:

1) Detailed information of wet material you are going to dry. We may ask you to provide composition report or samples for drying test.

2) Type of moisture.

3) Initial moisture content before drying

4) Required moisture content in dried product

5) Drying capacity in kg/h

6) Heat medium to be used for drying. Such as steam, thermal oil or hot water

Q: How the machine is delivered ?

A: Rotary vacuum paddle dryer is very heavy and its weight ranges from 3 tons to 50 tons. When the heating area is less than 60 M2, the dryer body can be shipped by 40 feet HQ container; 60-100 M2 should be shipped by 40 feet OT container; more than 100 M2, the dryer body has to be dismantled for shipping.

Q: What kind of after sale service you can provide?

A: We have professional after sale service team who can reach you in short notice. They can supervise the installation, do commissioning and train your workers.
