Solid substrates such as maize, WPS, solid and poultry manure are stored, processed and fed in solid form by the solid dosing system into the digester below the liquid level.
The KOMBI-Mix dosing system is suitable for biogas plants with a capacity of between 75 and 150 kW that process up to 12 m³ of biomass per day. It is designed to feed these plants according to their requirements.
The KOMBI-Mix has a dosing blade that processes the material to such an extent that the screw conveyor system can process it. The blade with plastic plain bearing prevents bridging by rotation above the screw discharge. The speed is 4 - 6 rpm and is thus matched to the discharge screws type 360 or type 450. The drive is provided by robust gear motors with a downstream cardan shaft and planetary angle gear. A shear bolt coupling is integrated in the drive train as a safeguard. The consistency of the material fed has a decisive influence on the removal rate of the system. Optimum operation is guaranteed with chopped renewable raw material.
For the processing of difficult substrates such as solid and poultry manure, vertical mixing screws made of stainless steel are used as standard. The mixing screws can be equipped with stainless steel cutting blades. The processed substrate is transferred to the subsequent feeding technology via a sub-screw. The dosing blade inside the dosing unit transfers the substrate to the feed screw mounted below the solids dosing unit. This ensures a constant feed rate.
A weighing system with control technology ensures quantity control. A wide variety of displays and computer controls are available. Communication of the weighing system and control with external controls is provided as standard.
The KOMBI-Mix can be supplied ready for connection, complete with a full electrical control system. On site, all that is required is to connect the main power supply, which simplifies installation.
We offer a range of conveying solutions for feeding biomass into fermenters. Our range includes screw conveyors with conveying capacities of up to 23 m³/h. Furthermore, the dosing systems can be adapted to different requirements and, on request, combined with additional feeding systems.
The components used are tailored to the requirements of biomass conveying and dosing and are designed for this specific application.
