Method for packing asphalt
Patent Name Packaging Method for Asphalt Patent Patent Applicant Poehner Engineering Co., Ltd. Principal Applicant Address Vienna, Austria Inventor A. Bonner Application (Patent) No. 200380108935.1 Application Date 2003.11.19 Certification Date Approval Publication No. 1738745 Auditing Announcement Date 2006.02. 22 Specification CD No. D0608-1 Main Classification No. B65B63/08(2006.01) I Classification No. B65B63/08(2006.01)I; B65B3/12(2006.01)I Partition Original Application No. Priority No. 2002.11.22 AT A1757/2002 Abstracts The present invention provides a method of packaging bitumen, in particular road building bitumen, in large volumes of disposable transport units to transport the bitumen in a cold state. In order to enable such disposable transport units to be accurately filled and processed, they are made of a flexible plastic having a melting point between 20°C and 50°C higher than the softening point of the asphalt, and the asphalt is cooled to near the point before filling. The corresponding softening point temperature. The workshop where this method is implemented has a plate heat exchanger for cooling the asphalt. In the plate heat exchanger, the temperature difference between the coolant and the pitch at the outlet of the heat exchanger is maintained in the range of 10°C to 25°C. Sovereignty item 1. A method of packaging asphalt, in particular road-building asphalt, in a large volume of a disposable transport unit to transport the asphalt in a cold state, characterized in that the disposable packaging unit is of a lower melting point than asphalt. The softening point is made of a flexible plastic having a height between 20-50°C, and the asphalt is cooled to a temperature close to the softening point of the pitch being processed before being filled.
