A process for the recycling of PET flakes from comminuted PET bottles, wherein the flakes are subjected to a washing treatment, are treated for at least 20 minutes in at least one washer at an elevated temperature higher than 70&deg; C. with a cleaning solution which contains caustic soda, and at the same time are also mechanically and hydraulically treated.

Method for recycling pet components and device for carrying out said method

A pasteurizing system for spraying liquids onto containers such as bottles and cans has a conveyor for conveying the containers and one or more spray tubes mounted parallel to the conveyor's plane of motion. Each of the spray tubes has outlet openings longitudinally distributed along its bottom side, and the inside cross section of the spray tube decreases along its length from a liquid inlet end of the spray tube, to an opposite end of the spray tube.

Device for spraying liquids onto containers

Rows of bottles are conveyed on parallel running belts. Closed loop flexible members such as roller chains, run in vertical planes along the longitudinal edges of the belts in the same direction as the belts. The closed loop chains have stabilizing devices mounted to them for stabilizing the bottles in each row as they move along on the belts beyond a bottle infeed region. The stabilizing devices each constitute a pair of fingers that are pivotally mounted to pins that stand up from the closed loop chains and are spring biased so that they diverge at a predetermined angle from each other when they are not restrained from doing so. As the sets of fingers are carried around on the chain, they reach a region where the bottles are deposited on the belts. At least in this region, the fingers of the stabilizing devices arrive between parallel plates which cause the fingers to pivot towards each other in an overlapping relationship so that they are clear from the pathway defined by the belts. After the bottles advance in a row, a small distance from where the fingers are restrained, the fingers emerge from between the plates and the springs cause the fingers to diverge at an angle from each other and establish contact with bottles on the belt to stabilize them. The fingers swing in a horizontal plane so they use none of the head room above the bottles, thereby allowing for a more compact conveyor system.

Conveyor system for containers

A machine for the cleaning of bottles having an endless conveyor for transporting the bottles through the machine and past associated treatment devices, the endless conveyor being guided in a horizontally extending, spiral-like path through at least two portions of the machine, the path of travel extending in one direction in a first portion and in the opposite direction in a second portion, the two paths of travel of the endless conveyor being disposed one above the other within the machine.
