茶叶杀青燃气红外线燃烧系统
一．杀青的要求
杀青是茶叶加工中必不可少的一道工序，而且杀青质量的好坏，直接关系到茶叶品质的高低。
杀青锅（滚筒）的温度和温度的均匀性决定杀青质量，高品质的茶叶不仅要求升温迅速，而且要求杀青设备的温度均匀一致。
茶叶杀青设备也必须尽可能地节能，以降低杀青费用。
The Gas-Fired Infrared Systems to Tea Water-Removing Machines
Re of tea water-removing
Water-removing is essential to tea processing which is directly related to the of finished products.
Heating rapidly and better temperature uniformity are necessary to make high- tea.
Tea water-removing device must also be energy saving as much as possible in order to reduce costs.
二．蓝炬燃气红外线杀青燃烧系统的特点
1． 采用全预混燃烧的金属纤维燃烧器，燃烧充分、红外线辐射效率高、燃烧均匀、不易回火、使用寿命长；
2． 采用密闭式燃烧加热系统，相比开放式系统，整体节能30％以上；
3． 升温迅速：由于金属纤维燃烧器的热惯性小，点火后数秒内即达到工作温度；
4． 采用程序控制器的燃烧控制系统，具有吹扫、自动点火、火焰检测、压力保护、意外停机报警等功能；
5． 依据控制精度要求，温度控制可采用两段火型式或PID控制；
6． 杀青滚筒温度均匀，纵向温差不超过±5℃。
7． 可采用液化气或天然气作为气源。
The characters of BURNRAY Gas-fired infrared systems
1. Adopt metal fiber burners based on complete premixed combustion which have advantages of higher combustion efficiency, larger radiation coefficient, good flashback resistance and long lifetime;
2. Compared to open combustion system, the hermetic combustion system can save the energy over 30%;
3. Fast heating (small thermal inertia): several seconds to heat up to the operation temperature;
4. With program controller, the control system has various functions: pre-purge, automatic ignition, flame detection, pressure protection and broken-down alarming;
5. Temperature control can adopt two-stage flame or PID mode based on the demand to precision;
6. Good temperature evenness: vertical temperature difference of the c
