PREOL installs stainless-steel silos for rapeseed meal
- Two rapeseed meal tanks were replaced by modern stainless-steel silos.
- Construction and commissioning of one silo, including insulation and measurement/control systems, was completed in just under three months.
- Modernization was carried out without restricting production despite operating with half the storage capacity during works.
- New features include 3D scanners for stock measurement, drive-in Bobcat access for cleaning, and three larger inspection openings for safer maintenance.
Project and schedule
PREOL replaced two rapeseed meal storage tanks with stainless-steel silos. The complete construction and commissioning of one silo, including insulation, electrical installation and measurement and control systems, was accomplished in just under three months. The modernization proceeded without any restriction on production, although PREOL temporarily operated with half the rapeseed meal storage capacity, which increased demands on construction, operations, storage and logistics.
Construction method
Assembly began with a starter segment supporting the roof and connecting bridge structure. Using multiple hydraulic jacks the roof structure was gradually lifted while additional circular segments were added underneath; the sequence was repeated until the silo reached the required height.
Operational and maintenance improvements
The new silos are equipped with 3D scanners that map internal meal distribution and precisely calculate quantities, improving stock visibility. A skid steer loader (Bobcat) can drive directly into the silo to simplify cleaning, and three larger inspection openings allow more convenient interior inspection and safer access during maintenance. The stainless-steel construction is expected to deliver longer service life and easier maintenance.
