Principle   

1.Liquid material is dried by heat transfer when loading on rotating roller drum surface. Liquid film is spread on rotating roller drum by feeding equipment. Roller drum is heated by heating medium(could be steam or transfer oil). Dried liquid film is scraped by scraper. Then dried product is transferred to store tank by screw conveyor. Exhaust air could be directly discharged to atmosphere or after filtration.

2.Roller drum dryer is consisted of roller drum(cylinder drum, cover of two ends, axis of ends and bearings), liquid material feeder(include liquid trough), scratching device(include scraper, supporting frame with pressure regulator), driving system(include motor and reducer), heating medium(steam) and the input & discharge device, dried product conveying device.

  Features

 1.High heat efficiency. The principle of heat transfer of the roller drier is heat conduction and the conducting direction keeps uniform in the whole operation circle. Except heat loss of end cover and radiation loss, all heat can be used for evaporating the damp materials on the wall of the roller . The efficiency can reach 70-80%.

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

3.Short drying period. The drying period of materials is normally 10 to 300 seconds,so it is suitable for heat-sensitive materials. It also can be reducing pressure operated if it is put in vacuum vessel.

4.Fast drying rate. As film of materials coated on the wall of the roller is very thin.Normal,thickness is 0.3 to 1.5 mm, plus directions of heat and matter transmitting are identical, the vaporing strength on the surface of the film can be 20-70 kg.H2O/m2.h.

 Technical parameter 

Cooling system 

To congeal a molten product the crystallization heat of the product must be removed. This is transferred via the drum flaker's wall. The heat is relayed via the drum body to the cooling agent, which is usually water. The cooling water is sprayed with a special spray pattern against the inside of the drum using a central spray pipe.

From it feature. It can be divided into single and double cylinder. Otherwise, from its operate press, it can be divided into ordinery press and minus press drier.

Changzhou YIBU drying equipment CO.,Ltd was awarded the China famous trade mark. Our company become the first drying company who  become the China famous trade mark in China.

Until now YIBU has more than 250 people,with 25-year-old.The founder, Mr Zha Guocai devotes research, manufacture, production and business of drying equipment for over thirty years, holds the post of Deputy Director-General of China Drying Equipment Association for a long time.The company pays much attention to science and technology renovation. First or later, it has cooperated with the institutes that are Shanghai, Wuhan, Chongqing and so on, and cooperated with Shenyang Chenmical Institute, Ministry of Chemical Industry, Qinghua University, Shanghai Transporation University, Dalian Science and Technology University. Therefore the company can put 3-5 new varieties into the market every year. In 1998, through approval of state relevant departments, the company set up China Research Center of Drying and Granulating, that can research new process and develop new technology and provide new products for pharmaceutical, chemical and foodstuff industries. We have many testing machine in our lab for to make trials for clients.
