电加热型：
　　1：经我厂多年研究，由朋友糕点厂实验，成功做成了6米长的小型隧道炉，该隧道炉比10米至20米长隧道炉大大降低了对电量的需求，一般中小糕点厂家在不另外增架变压器的情况下都可使用，因改炉较短，也解决了中小糕点厂品种多，而单品销量又不大用大型隧道炉不合适的难题，所以该炉实是一种可多品种生产，灵活变化而又节能环保的设备。
　　2：该炉采用双盘进料，链板传动，无极变速，可根据各种产品不同的烘烤时间来调节速度，上下加温，分为前后两个温区，上下温度，前后区温度，可根据品种随意调节，设定好后自动控温，方便稳定。

　　导热油型：
　　导热油型制造要比电加热型的复杂一些，但性能和设定与电加热型一样，只是加热源不同，该炉适合电量不足地区的厂家使用，另我厂也承接大型隧道炉的定作，欢迎有需要的朋友来电咨询。

   Electric heating type:
1: after our many years of research, the friend pastry factory experiment, success made 6 meters long small tunnel furnace, this tunnel furnace more than ten meters to twenty meters long tunnel furnace greatly reduce the electricity demand, generally small and medium-sized pastry factory in another increase frame transformer may use, for change furnace is shorter, and solved the small and medium-sized pastry plant varieties, and single product sales and don't use large tunnel furnace inappropriate problem, so the real is a kind of can much variety production, agile change and energy conservation and environmental protection equipment.
2: homogeneous with double disc feed, chain plate drive, and infinitely variable speed, can according to various products of different baking time to adjust the speed, and the upper and lower heating, before and after pided into two zones, and the upper and lower temperature, and area temperature, according to variety adjust at will, has been set to be automatic temperature control, convenient and stable.
Heat conduction oil type:
Heat conduction oil type manufacturing than electric heating type more complicated, but the performance and setting and electric heating type, just different heating source, the suitable for electricity shortage region, and the other manufacturers use we also undertake large scale tunnel furnace's set, welcome friends in need to inquire.
