TRT Triplex dryer

Lowest energy consumption and proven technology

Design and manufacture of plants for the drying of the most different materials have been among our core competences for years. With our wide range of experience in drying technology and constant research and development, we can offer the optimum solution to any drying problem. With its proven design and reliable operation, the Pfeiffer TRT Triplex dryer scores with low energy costs and constantly high output rates. Maximum capacity at minimum consumption – utmost efficiency: this is what is needed nowadays and what Gebr. Pfeiffer has to offer.

Advantages of the TRT Triplex dryer

Gentle material treatment

No overheat due to the uniflow principle.

Low thermal energy consumption

Minimum heat loss by radiation thanks to small dryer surface and uniflow principle.

Low space requirement

Three concentric dryer tubes for reduced dryer length, hence low capital expenditure for building and foundations.

Short starting and stopping phases

Temperature-resistant steel plate liners instead of ceramic liners.

Working principle

The TRT Triplex dryer operates on the uniflow principle, i.e. material and hot gases flow in the same direction and pass through the dryer tubes from the center outwards. The material to be dried is fed into the innermost tube, it passes through the dryer and is discharged through double pendulum flaps fitted to the dust jacket. The residual moisture of the dried material is set by controlling the exhaust gas temperature and dwell time of the material in the dryer. The hot gas required is produced in a combustion chamber, using solid, liquid or gaseous fuels. Process gases can be used as well. The dryer exhaust gases pass through a filter for dust collection.
