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.

Triple-Pass Rotary Dryer for
Drying of Biomass Fuel in Pellet/Briquette Production
Introduction to Biomass Dryer:
Biomass dryer adopts belt conveyor to feed the wet material into the drying drum; biomass burner (also coal, oil, or gas) to be the heat source, cyclone to collect the dust, draft fan to get the steam and moisture into the air, and electric control cabinet to control the whole system. The biomass drying system has the advantages of high-degree automation, reasonable process, stable performance, simple operation, wide applicability, etc, and are widely used in drying sawdust, wood chips, wood pellets, straw and other biomass, whose production capacity is as high as 12 tons per hour.
Features of Our Biomass Dryer:
1. Lengthened triple-pass Structure, reliable performance, workshop area reduced by 40% min.
2. Our sawdust dryer is designed with anti-sticky drum-wall and specially-designed fligLD lifters.
3. It has big drying capacity, the material well contact with hot air, heat efficiency as high as 80%.
4. Our rotary drum dryer is of low noise, little pollution and good drying effect.
Working principle of Biomass Dryer:
Biomass drying system consists of heating device, feeding device, conveying device, discharging device, dust extraction device and other accessory equipment. For the installation process, the rotary drum dryer should slopes sligLDly so that the discharge end is lower than the material feed end in order to convey the material through the rotary drum dryer under gravity. Material to be dried enters the rotary drum dryer, and as the rotary drum dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the rotary drum dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the rotary drum dryer , passing through the hot gas stream as it falls.
Introduction To Triple Pass Rotary 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. |

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 a
proportion 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.

| About Us |
|
Our drying equipment factory was established in 1950s with technoloLD assistance from Russian experts. Since then the factory has never stopped pursuit of upgrade of our drying equipment, many specially designed dryers for challenging materials had been developed during even 1960s-1970s without any outside help. The spirit of constant pursuit on technoloLD upgrade and commitment to quality and process optimization had passed on from generations to generations.
Today, with an open mind and eagerness to better serve customers, we had learned from western counterparts, integrated European technoloLD into our products selectively according to our current industrial circuLDtances in China based on our past experiences, which makes our products more effective, competitive and much easier for customers to accept. We are proud of products that had provided numerous businessmen new opportunities and even more workers jobs, all of which had been indispensable in our social welfare improvement and industrial development.
Time had witnessed our growth and we shall never cease to change times with our products.
To all ambitious and hardworking entrepreneurs all over the world, we offer our products to change your tomorrow for the better and better. Please give us a call for your requests. We are at your disposal at any time. |
