20.07.2020 Lödige wins major export order

Gebr. Lödige Maschinenbau, Paderborn, Germany (better known internationally as Lödige Process Technology) despite the economic effects of the coronavirus pandemic, has won one of the largest single orders in its 80-year-plus history: This comprises a total of six machines which are to be delivered to an Asian chemical company.

More specifically, the scope of supply consists of five large reactors of the Druvatherm® DVT series each with a drum volume of over 20,000 litres and an additional smaller pilot machine for product and process development. The reactors are employed to chemically convert cellulose fibres under high pressure so that they can then be used by the building materials, food and pharmaceutical industries.

Lödige's Druvatherm reactors can perform several process steps – for instance reaction and drying – in a single machine under ideal conditions. This offers many advantages. Firstly the process takes less time, as no discharge, in-house transport and refilling is required between steps. Secondly, a single Druvatherm reactor requires less space than several separate units used for different process steps. These discontinuous machines are characterised by special mixing elements installed in a cylindrical, horizontal drum with a temperature control jacket. The mixing elements move the reaction material continuously. This ensures that individual particles frequently touch the container wall, thereby optimising the heat transfer and reducing process times. This major order emphasises the continued importance of the Asian market for Lödige. The machines are scheduled to be manufactured by 2021.
