Drum drum

1scrapePlate dryer is an internal heating conduction type rotary drying equipment. Wet materials obtain heat transferred by thermal conduction on the outer wall of the drum, remove moisture, and achieve the required moisture content. The heat is transferred from the inner wall of the drum to the outer wall, and then passes through the material film. It has high thermal efficiency and can be operated continuously, so it is widely used for drying liquid or strip materials, and is more suitable for paste and viscous materials.1、 Characteristics:

、high thermal efficiency

：The heat supplied inside the cylinder, except for a small amount of heat radiation and heat dissipation loss at the end cover of the cylinder, is mostly used

Wet separation gasification, with a thermal efficiency of up to 70-80%

2. High drying rate：

The heat and mass transfer process of the wet material film on the cylinder wall is consistent from the inside out, with a large temperature gradient, which maintains a high evaporation intensity on the surface of the film, generally up to 30-70kg H ₂ O/m ². h.

3. The drying quality of the product is stable：The drum heating method is easy to control, and the temperature inside the drum and the heat transfer rate between the walls can be relatively stable, allowing the film to dry in a stable heat transfer state and ensuring the quality of the product.

4

Widely applicable：

Liquid phase materials dried by drum drying must have fluidity, adhesion, and thermal stability. The form of the material can be solution, heterogeneous suspension, emulsion, sol, etc. It can also be used for strip materials such as pulp, textiles, and celluloid.5. Single machine production capacity：

Due to the limitation of cylinder size, the drying area of a general drum dryer should not be too large.monocular

Dry area, rarely exceeding 12m2. The ability of equipment of the same specification to process liquid is also affected by factors such as liquid properties, moisture content control, film thickness, and drum speed, with a large variation range, generally between 50-2000kg/h.6. Convenient heating medium：Commonly used saturated water vapor, with a pressure range of 2~6kgf/cm2, rarely exceeding 8kgf/cm2.For some

Require to dry at low temperature
For dry materials, hot water can be used as the heat medium: for materials that need to be dried at higher temperatures, heat medium orHigh boiling point organic compounds are used as heat media.2、 Structural form:roller

It can be divided into two forms: single cylinder and double cylinder dryers. Additionally, it can be divided into two forms based on operating pressure: normal pressure and reduced pressure.3、 Technical parameters:

Note: If required by the customer, we can design and manufacture an upper feeding double drum dryer for them.4、 Installation：roller

The installation system should be arranged according to the overall plan, with a flat ground. A pressure gauge and safety valve should be installed at the inlet of the steam pipe, and the flanges of each steam inlet should be firmly connected.5、 Application area

：Changzhou

The drum scraper dryer of Runkai Drying is mainly used for processing liquid materials. It can be heated and dried with steam, hot water or hot oil, or cooled and solidified with cold water. Different feeding methods such as immersion, spray, and grinding can be used according to the properties of different materials and process requirements.6、 Adapt to materials：roller

Suitable for drying liquids or viscous materials in industries such as chemical, water purification agents, copper sulfate, animal glue, plant glue, dye yeast, antibiotics, lactose, starch slurry, sodium nitrite, dyes, distillation waste liquid, sulfur blue, penicillin residue, wastewater protein extraction, metallurgy, etc.
7、 Maintenance

：1. Regularly check the flexibility of rotating parts and whether there is any jamming phenomenon. Chain wheels and other components should be lubricated regularly, and measuring devices such as pressure gauges should be calibrated regularly for errors. If there is severe wear on the triangular belt transmission components, they should be replaced in a timely manner.

2. For maintenance of electric motors and reducers, please refer to the instructions for use and maintenance of electric motors and reducers.8、 Debugging：1roller
