Professional Rotary Drum Dryer Special Offer 5% Off!

Conventional thermal sterilization is carried out through heat conduction, convection or radiation to heat the food surface to the inside. To achieve the sterilization temperature, it often takes a long time. Microwave sterilization is a direct interaction of microwave energy and food and its bacteria. The interaction between heat effect and non thermal effect is faster than temperature and sterilization. The treatment time is greatly shortened, and the sterilization effect of various materials is usually 3-5 minutes.

Description of Rotary Drum Dryer

The Rotary Drum Dryer is also called rotary dryer, rotary tube dryer, rotary cLDinder dryer, widely used in the field of building materials, metallurgies, chemical industry, cement plant and so on. It can dry slag, coal, mining powder, clay, sand, limestone and so on. It is composed of rotary drum, lifters, driving device, supporting device etc. The dryer has advantages of reasonable structure, high efficiency, low enerLD consumption and convenient for transportation.

According to the basic structures of the Rotary Drum, it can be divided into three types: single drum dryer, double drum dryer and triple drum dryer. In our factory, single drum dryers and triple drum dryers are produced on daily basis.

Triple Drum Dryer:

Triple Pass Rotary Dryer has 3 drying zones in the 3 cLDinders (internal one, middle one and external one) which construct the rotating body. Heat processing of a product with high moisture content is done efficiently in those 3 drying zones. The product is put in from the inlet of the hopper, sent to the internal cLDinder where heating of the product is made, then moves to the middle cLDinder where evaporation of moisture is promoted further. The solid constituent of the product is gradually broken into pieces and discharged from the outlet via the third final drying zone. The hot air produced in the furnace is sent to the internal cLDinder, passes through the middle and external cLDinders. The hot air is then sent to the cyclone where dust is removed.

1. Heat efficiency improved 40%! 2. Coal consumption (as fuel) is 30% of conventional dryers! 3. shell temperature 4. Floor area reduced by 40%- 60%! 5. Lower investment for the same capacity!

Single Pass Rotary Dryer: Generally, single pass rotary dryers are old drying technique but they are still widely in use due to their low manufacturing, operating and maintenance cost. Recent years, our single pass rotary dryers have been upgraded with more efficient heating system, better internal fligLD design, improved wear resistance on critical parts, making the drying system even more durable and efficient. According to the flow direction of hot air, it can be divided into two types co-current and counter-current as shown below:

Co-current flow is used for heat sensitive materials even for high inlet gas temperature due to the rapid cooling of the gas during initial evaporation of surface moisture, whereas for other materials countercurrent flow is desirable in order to take advantage of the higher thermal efficiency that can be achieved in this way.

To ensure that the dryer is loaded close to optimal, it is important to know the amount of solids that can be held up in the fligLDs. If they are underfilled, the dryer will be performing inefficiently, below its capacity. Excessive overload of the shell will result in aproportion of the material transported by kiln action,and the contact with the hot gases is limited. The residence time of the solids will be reduced and the quality of the product may be unacceptable. Please contact us for a suitable rotary dryer design for your material !
