  • Easy to change parts on site


Design and function of the liquid feeding system
How the CC-Mix works

The liquid feeding system CC-Mix combines proven components in a well-thought-out concept. It is based on the unique, easy to maintain progressive cavity pump of the CC series, supplemented by a generously dimensioned mixing chamber. The biomass (e.g. maize silage, dry chicken manure, grain meal, but also sugar beet pulp, ruminal content or fruit and vegetable waste) is transported by a feed screw from the side or from above into the mixing chamber. At the same time, a liquid suspension, such as recirculated material, is added at the start of the mixing chamber. The rotary grinder on the mixing shaft catches the biomass, and transports it – thanks to the new design – actively into the liquid suspension. The ripping teeth and paddles on the mixing shaft intensively mix up everything to a homogeneous organic suspension. The pump unit after the mixing chamber pumps the mashed suspension into the digester(s). A pipe network allows multiple digesters to be fed by one liquid feeding system CC-Mix and it is easy to connect additional tanks later on. The CC-Mix thus provides the conditions which are necessary for optimum fermentation of the biomass using energy efficiently. At the same time, the effective mixing action ensures optimum extraction of foreign matter in the integrated foreign matter separator.

Service and maintenance of the liquid feeding system CC-Mix
Quick and easy thanks to the QuickService concept

CC-Mix is the solid matter feeder which is easy to service and maintain.

Parts are quick and easy to replace, thanks to the innovative QuickService concept of the CC-Mix: The rotor and stator swivel out as a unit for quick and easy removal and replacement. If necessary, the mixing shaft can be removed in just a few steps. Feeding downtimes due to service and maintenance are reduced to a minimum.

The tried-and-trusted QualityCartridge is used for the shaft seal. Since it is a preassembled mechanical seal, it can be quickly and easily replaced on site. Once the parallel shaft geared motor has been removed, the seal is easy to access and can be replaced in a few simple steps. No other dismantling work is necessary on the CC-Mix.

Control technology for Vogelsang technology

Investing in our progressive and smart control technology significantly boosts the performance and efficiency of Vogelsang machines and systems. It captures and continuously monitors key parameters like the capacity or throughput rate, rpm, pressure and power consumption. The control detects malfunctions early, and rectifies them by intervening appropriately. The integrated communication interfaces like ProfiNet and OPC UA can exchange data with other systems or a superordinate control in real time.

At the same time, the web-based user interface displays all key data clearly in all major browsers. Optionally, the data can be accessed on mobile devices for remote monitoring.

Our experts’ experience from hundreds of applications in various areas constantly inspires our software development and lays the foundation for the major benefits for the users: low operating costs, maximum availability and efficiency.

Our range of controls offers the right solution for all machine requirements and all customers’ needs. From ready-to-use, factory-tested and commissioned system solutions for end users, to basic versions for experts who want to put the finishing touches to the control technology themselves.

Features of the CC-Mix

The unique design of the CC Mix stands for the best possible mixing performance with minimal energy requirements. Through the intelligent arrangement of solid and liquid feeds as well as the mixing shaft, floating layers are avoided and the biomass is actively transported in the liquid, to intensively mix both to a homogeneous organic suspension.
At the base of the mixing chamber, directly before the pump unit, the CC Mix has a foreign matter separator as standard, which separates out stones and metal parts using gravity.
Thanks to its compact design, the machine is easy to integrate. It is even no problem to retrofit it into an existing system. For three steps in your process, you only need a few square meters, which includes space for service and maintenance.
Both the progressive cavity pump in the CC series as well as the components in the mixing chamber are easy to service. On the basis of the QuickService concept for the CC series, all of the parts, from the rotor-stator unit, via the shaft seal through to the tools on the mixing shaft are easy to replace on site.
The CC Mix is driven with a sturdy parallel shaft geared motor with a high operating factor. This is mounted directly onto the drive shaft so an additional coupling is not needed.
Both the mixing chamber as well as the mixing shaft, as well as all of the steel parts in the mixing chamber are made of corrosion-resistant stainless steel or some other corrosion-resistant material. The sturdy design is the basis for the intensive and energy efficient preparation of the biomass.
A generously sized cardan shaft with two cardan joints ensures reliable transmission of the drive power in the CC series from the parallel shaft geared motor to the rotor. A sturdy sleeve – which doesn’t even have to be disassembled when changing the rotor – protects the shaft against solid and fibrous matter and against foreign matter in the medium.

Options of the CC-Mix

The progressive cavity pump used in the CC series is optionally available with a two-stage geometry. This increases the permissible differential pressure, halving the pressure difference per stage, resulting in a longer service life, even with strongly abrasive media and/or high pressures.
On request, the Performance Control Unit (PCU) is available in a variant with a PROFINet connection.
The optional wide screen touch display offers an overview of all of the important information and settings, even outside of the central control. Built into the control cabinet door, all important details are easy to access and set via the intuitive menu.
Optionally, Vogelsang can also offer control hardware and software including the sensors from just one source.
All PCUs are equipped for access via remote maintenance. If access is activated and made possible, operators benefit from uncomplicated software updates and, when events call for it, we can quickly and easily support the customer.
