高端燃气供料道通过简易的操作即可实现热稳定性和冷却性能。可按需要加热中部和边缘玻璃液，提供更加灵活，更加准确的玻璃液状态调节和控制。
主要特征:
中部间接冷却方式
冷却段结构，使边缘获得更多辐射热量
匀化段盖板结构可使匀化段两侧独立加热
稳定精确的温度控制
采用“浸入式”热电偶
间接中心冷却方式：
色彩稳定性在使用有色玻璃（如琥珀色和绿色）时非常重要，高端供料道的间接冷却方式有助于保持恒定的氧化程度，维持玻璃稳定性。并且间接冷却可避免冷却风与燃烧气相混合，为加热和冷却系统提供较高的效率。由于间接冷却，冷却风的改变不会影响供料道内部压力。
冷却区内各独立的冷却风机，可以更加柔和的进行冷却，避免顶部玻璃液温度过低。
燃烧系统：
供料道加热系统既可使用液化气，也可使用天然气，并且，依据文丘里混合器和压力传感比例调节阀的设计，歧管压力范围可在20mm到250mm水柱之间调节。而基于流量传感比例调节阀设计的燃烧系统同样可供选择使用。
冷却风控制：
供料道采用变频器控制的独立冷却风机。虽然价格稍有增加，但与其节省的大量能源成本相比，必然物超所值。
玻璃液调节：
热调节是通过从热源移出热量取代边缘冷却导致的热损失。
说 明:
槽砖宽度 ：460mm–1371mm
出料量范围 ：3到150吨/天（取决于供料道宽度）
冷却方式 ：中部间接冷却
控制系统结构 ：标准的加热/冷却PID控制方式
测温单元 ：热电偶或光纤红外测温仪，依据玻璃类型选择或顾客指定。
燃烧系统结构 ：压力或流量传感器控制空气/燃气比例或者顾客指定。
玻璃类型 ：适用所有颜色的玻璃
卓越的料道：
三金燃气加热高端供料道不仅可以改善提高玻璃液状态，由于加强了冷却性能，还可以适用于更高出料量，更宽料滴温度范围的生产需求。

Shandong Sanjin Glass Machinery Co Ltd holds the chair of Vice-President in the China Glass Association and the China Light Industry Machinery Association.
The company was founded in 1959 as Shandong Light Industry Machinery Factory. In 2004, it was restructured into a private enterprise company. Shandong Sanjin is the “Shandong High Tech Enterprise”, “Provincial Contract Abiding and Trustworthy Enterprise”, “Provincial Technology Center”, “Shandong Glass Machinery Engineering Technology Center” and “Postdoctoral workstation”. Selected by China Glass Association，Sanjin was awarded as the “China Enterprise and Entrepreneur” and “2nd batch of Shandong Credit Enterprise”. “Sanjin” brand was selected as “Shandong Famous Brand”.
In 2011, Shandong Sanjin was converted into a Joint Venture company with Emhart Glass SA, a division of Bucher Industries AG, Switzerland. Emhart Glass SA is a world leader in Glass bottle making machinery and the Joint Venture brings together a world class leader and Sanjin, a leader in China Glass machinery.
Shandong Sanjin main products are in IS machines, Anneling Lehrs, Feeders，other Glass Machinery equipment and has more than 60% share in China domestic market. It also has a building materials machinery business.
Since the JV, Shandong Sanjin has embarked on upgrade and transformation, with focus on improved technology, equipment investment and quality. It has invested RMB150m in CNC machining centres, Co-ordinate Measuring Machines and other high end production equipment as well as a new painting line. These investments will enable the company to move to a higher level of competitiveness and quality in its manufacturing processes. In addition, the company will also invest in a new ERP system in order to improve its management level.
In the area of R&D, the company worked with Emhart Glass and developed the first CIS machine in China, in order to meet higher domestic customer expectations as well as to penetrate the international market. The response to the new CIS machine has been encouraging.
Shandong Sanjin will work towards the philosophy of "Build Sanjin brand, create Sanjin for one hundred years". By learning advanced technology from overseas, be a qualified supplier of Emhart and a world-class manufacturer in glass bottle machinery industry.
