A、Main body of machine which consists of transversally inputting and conveying platform, adjustable pulsator and spreading roller in the bottom. B、Upper portion of machine which consists of height adjustable overflowing equipment, hot wind blade, thermal radiating elements with adjustable heating power. C、Low portion of machine which consists of Mobile Temperature- Preserving Stirring Cylinder, Control System of Hot Water Circulating with Constant temperature. D、Ranking and conveying machine and electrical control system. Functions: Pump the chocolate paste to overflowing equipment in upper portion of machine from temperature preserving and stirring cylinder in the bottom of machine. Then spread the chocolate to conveyed products transversally incoming from steel wire, finally, output them after hot wind processing. Working Principles: Products are pushed out of ranking machine, enter into conveying platform transversally through steel wire, evenly covered with chocolate paste, then delivered to tunnel cooler after hot wind processing.
