| 2000S-DRAP ( Model 2000S-DRAP Duplex Single Worm Refiner- Pelletizer Plodder ) | |||||||||||||||
| Features | |||||||||||||||
| ， The upper extruder acts as a refiner with milling device, while | |||||||||||||||
| the lower extruder acts as a plodder; There is a vacuum | |||||||||||||||
| chamber connecting the two extruders, inside which a level | |||||||||||||||
| sensor is installed. | |||||||||||||||
| ， Barrel is made from cold-drawn stainless steel tube 2 mm thick. | |||||||||||||||
| ， Worm is of lightweight, made from stainless steel. The newly | |||||||||||||||
| designed worm for plodder has soap pellet feeding zone, soap | |||||||||||||||
| stock compression zone and soap stock pressure stabilizing zo- | |||||||||||||||
| ne.So that a strong thrust force is produced, the soap barsss | |||||||||||||||
| extruded has excellent qulity. | |||||||||||||||
| ， At upper extruder, refiner, milling is effected by a device | |||||||||||||||
| installed at the outlet end of the worm. The milling device is | |||||||||||||||
| composed of a piece of filtering sheet; a stationary perforated | |||||||||||||||
| milling disk and a perforated rotating disk. The soap stock is | |||||||||||||||
| vigorously milled in the space, forming superfine particles of | |||||||||||||||
| 0.01mm level. This optimal milling makes soap stock translucent | |||||||||||||||
| and extremely fine. | |||||||||||||||
| ， The filtering sheet developed in 2002 has holes of 0.03 mm, is | |||||||||||||||
| the only design in the world. | |||||||||||||||
| ， The cooling of barrel begin from the very end where milling | |||||||||||||||
| device is located; the pneumatic cooling water inlet/outlet | |||||||||||||||
| valves controlled by PLC to obtain a optimal cooling effect, | |||||||||||||||
| that means maximun output of the machine. | |||||||||||||||
| ， The speed reducers have their gear wheels with case- | |||||||||||||||
| hardened and ground teeth. | |||||||||||||||
| ， Pneumatic clutches are used between motors and speed | |||||||||||||||
| reducers to make smooth startup. | |||||||||||||||
| ， The upper extruder, refiner, is controlled by a level sensor | |||||||||||||||
| made by Enders-Hauser, Germany. | |||||||||||||||
| ， Touch screen is used for control and operation, it is fault-free | |||||||||||||||
| and a good interface for communication between operator and | |||||||||||||||
| machine. | |||||||||||||||
| ， The electric panel is supplied by Rittal, Germany; the adjustable | |||||||||||||||
| frequency AC drive by AB or ABB; PLC by Omron, Japan; and | |||||||||||||||
| touch screen by Delta; 95% electic components are by | |||||||||||||||
| Schneider, France; while pneumatic components are by Norgren | |||||||||||||||
| Martonair, UK. | |||||||||||||||
