Fines extruders for bar soap drying plants

During the drying process, soap residues are isolated from the vapours produced during the previous processes by the fines separator. This waste can either be collected in the lower part of the machine and then disposed of when the plant is not running, or it can be recovered from the still running plant through the use of so-called fines extruders.
Soaptec designs, manufactures, and installs the latest generation of fines extruders for bar soap drying plants, developed in-house by a team of highly skilled engineers, technicians, and workers. Tailor-made to meet the needs of our customers, our fines extruders can be mounted both on new Soaptec plants as well as on production and finishing lines manufactured by other companies.
Our team is available to travel worldwide for pre and post sales support.


The models


Soaptec offers two fines extrusion models: the FC-150, which allows the fines recovered from the separators to be transported inside the atomiser, and the FE-150, which allows the residues to be extruded directly into the atmosphere.
Fines extruders are real extruders, but on a smaller scale. They consist of a barrel containing a screw that is driven by a gear motor with a thrust bearing.
The FC-150 fines conveyors are used to transport fines from one separator to another, or directly from one separator into the atomiser. The soap, which is still in powder form, is discharged from the screw through a screen.
The FE-150 fines extruders can compress the powders and extrude the soap in the form of small cylinders through a perforated plate into the atmosphere and cut them with a knife that is guided by the motion of the screw itself.

Characteristics and technical specifications


Soaptec has made the quality of its products its most important feature, which is why we carefully select all the materials with which the machines are built and work in full compliance with ISO and ASME standards.
For the construction of the parts of the FC-150 and FE-150 fines extruders in contact with soap, we have chosen AISI 304 stainless steel, an extremely durable and resistant material. The screw, on the other hand, is made of cast aluminium and machined to tolerance.
The load capacity is tested according to UNI, DIN, AFNOR, and AGMA standards.
The vacuum system is guaranteed by mechanical seals mounted on the drive shafts of both the screw and the bridgebreaker.
The upper part of the hopper is equipped with an independently operated bridgebreaker.
The barrel, machined to ensure correct position of the screw, is equipped with a cooling jacket.
