Efficiency increase in the silage process - New concepts to minimize energy losses (EiS)
Project
Project code: JKI-PB-08-1222
Contract period: 01.02.2015
- 31.05.2018
Purpose of research: Project preparation activity
The goal of this joint-project is to increase the efficiency of the ensiling process in large silos for the provision of fermentation substrate for biogas production. The use of high-quality silage will increase the yield potential and simultaneously will reduce disturbance and damage to the system. Through the development and calibration of a multi sensor system for monitoring the silage process from filling to removal, it is possible to display and optimize the processes in large silos, which are typical for more recent biogas plants and are not well evaluated. The multi-sensor makes it possible to monitor the compaction at critical points, such as border areas during filling process. In addition, it is possible to react in an appropriate manner to the inhomogeneity of the fermentation substrate, which often occurs in large silos. Disturbances during the silage process and after removal can be detected early and can be resolved before they cause a reduction in silage Quality. By calibration of the multi-sensor system, losses occurring in practice can be quantified and new substrates can be evaluated. The use of a software standards common in cropping data management ensures that the sensor data can later be integrated into already established software solutions and thus transferred directly into practice. An optimized ensiling process enables operators an efficient and profitable operation of their biogas plant in the future.
Multisensor: general framework, measuring tasks defined: measurement of pH, density, temperature and GPS. Data is wirelessly transmitted to the base station. Measuring principles for physical parameter are defined and corresponding sensors tested. Modell-silo: await final dimension of sensor. Lab-silage: first measurement series with different density of maize-silage. Chemical and microbial analysis is ongoing. Outline of circuit board almost final. General interface electrically and mechanically set. Four case-prototypes printed. First test measurements in lab and silo successfully performed.
