Product Description

 Food Grade Drum Dryer Rolling Scratch Board Drier Rotary Scraper Dryer Price

Product Description

The rotary scraper roller drying machine is a kind of rotating continuous drying equipment with internal heating conducting-style. Certain thickness of materials film attach to the drum from material liquid vessel under the drum. Heat is transferred to the internal wall of the cylinder through pipes and then to the external wall and to materials film, to evaporate the moisture in materials film so as to dry materials. Dried products are then scraped off by the blade fitted on the surface of the cylinder, fall down to the spiral conveyor under the paddle, and are conveyed, collected and packed.

Main Features

                               Single drum type                                                          Double drum type                                                                  Multi-rolls type

1. High thermal efficiency. The principle of heat transfer of rotary dryer is heat conduction which heat conducting direction keeps identical with operation cycle. Except cap heat dissipation and radiation loss, all heat energy can be used for evaporating wet materials on the wall of roller. Thermal efficiency could reach 80%-90%.

2. Large operation elasticity and wide application. Various drying factors of the rotary drier can be adjusted, such as density of feeding materials, thickness of materials film, temperature of heating medium, rotating speed of roller etc, which can change drying speed. As these factors have no interrelations with each other, it brings great convenient to dry operation, and makes it applicable to suit various materials and to meet different requirement of production.

3. Short drying period. The drying period of material is normally 10 to 15 seconds, so it is suitable for heat-sensitive material.It can be also working under less pressure condition if it is put in vacuum device.

4. Drying rate is very quick. As material film coated on the wall of roller is very thin. Normally thickness is 0.3-1.5 mm, plus heat and mass transfer direction are identical, the evaporation capacity on the surface of film can keep at 15-70kg H₂O/m².h.

Working Principle

The drum scraper dryer is a kind of inner conduction type rotating continuous drying equipment, which realizes water evaporation or cooling and solidification flake formation by means of heat conduction.

The rotating cylinder carries out sticking or feeding through its lower trough or upper feeding device to dry liquid materials or ribbon materials attached to the outer wall of the cylinder. The material liquid that needs to be dried flows from the high-level tank into the receiving tank or feeding device of the drum dryer. The drying drum is driven by the transmission device and rotates at the specified speed. The material is formed by a film distribution device on the wall of the drum to form a film (adhered to a certain thickness of film, which can be adjusted by the film control device to ensure smooth drying of the material during rotation). The heating medium is continuously introduced into the cylinder to heat the cylinder. The heat transfer from the cylinder wall causes the moisture content of the material film to vaporize. Then, the material that meets the drying requirements is scraped off by a scraper, and spiral transported to the storage tank for packaging.

This machine is mainly used for processing liquid materials, which can be heated and dried by steam, hot water, or hot oil. According to different material properties and process requirements, feeding methods such as immersion, spray, and grinding auxiliary can be used.

 

Product Parameters

*  Install power is basic data, it will change according to specific material circumstances.
* Occupied area will be different because of different layout design according to customer's site.

Application

The rotary drum scraper dryer has widely used in food, chemical and other industries sticky, paste material production, drying and other processes. The typical such as yeast, baby food, rice paste, special process food additives, animal and plant feeds, milk powder for chocolate production, starch denaturation production process, potato powder, chemical dyes, etc

1. Chemical industry: In the chemical industry, a large number of chemical reactions and separation processes are required, often requiring the use of a large amount of solvents and water. Scraper dryer can effectively remove moisture and solvents from materials, improving product quality and purity.

2. Food industry: In the food industry, it is necessary to dry agricultural products, food, etc. The use of a scraper dryer can effectively remove moisture from materials, extend shelf life, and improve taste and quality.

Other industries: In addition to the above industries, scraper dryers can also be used for drying treatment in industries such as environmental protection, textiles, and papermaking.
