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.

Introduction to 3 Pass Rotary Dryers
3 Pass Rotary Dryers are one of the widely installed rotary drying equipment due to its reliable performance, high efficiency and low manufacturing cost. Our factory has been making rotary dryers for drying sand since 1950s. Back then only single-pass rotary dryers were available for all drying processes. As entering 21st century, all industries facing more and more environmental challenges and higher demand for enerLD efficiency. Our factory started to R &D 3 Pass Rotary Sand Dryers in 2002, which now has basically replaced conventional single-pass rotary dryers in drying pourable matarials lLD sand, animal feed,etc. .

Features of 3 Pass Rotary Dryers
⇒ Thermal efficiency improved by 40%
⇒ Coal consumption (as fuel) is 30% of conventional dryers.
⇒ Outer shell temperature reduced to less than 60 oC; exhaust gas below 120 oC. filter bags can work twice longer and no need for cooling.
⇒ Floor area reduced by 40% to 60% by comparison
⇒ Lowered investment for the same capacity.
⇒ Improved sealing and improved reliability.

How Does It Work ?
| 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 |  |
