Automatic ingredient dosing for medium quantities
The MacDos (Macro Ingredients Dosing System) small component weighing system automates the handling of bulk material ingredients in the food, chemical, and pharmaceutical industries. The system is suitable for storing, sequential dosing, and highly precise weighing of up to eight free-flowing to poor-flowing bulk materials. With larger raw material hoppers, increased dosing capacity, and various agitator options, the MacDos dosing system expands both the capacity and the portfolio in the field of automatic micro-ingredient dosing. The main area of application is the food industry, with a growing trend toward industrial-scale ingredient systems integrated into fully automated large-scale plants.
Compact, fully automatic dosing station
The modular design allows recipe-controlled dosing of small ingredients as a fully automatic system with direct transfer to the subsequent process. Sequential batch dosing from 2 to 8 containers—arranged in a circular or rectangular layout—into a centrally positioned hopper scale, followed by batch transfer to a pressure or vacuum conveying vessel and pneumatic transport into the subsequent production process. Negative weighing with direct transfer or dosing into a container or conveying line is also possible. Users benefit particularly from:
• Modular and compact system
• Fully automatid dosing system
• High dosing accuracy
• Recipe control
Product advantages
High dosing accuracy
Our dosing systems stand for precise and reliable material feed. Powerful dosing screws with frequency converters enable fine adjustment between coarse and fine flow. The optional shut-off flap ensures clean cutoff, while automatic overrun correction guarantees an exact final quantity. The result: consistent quality, less material loss, and maximum efficiency.
Flexibility
The modular design allows for optimal adaptation to a wide range of requirements. Different hopper sizes, installation and filling options, and a wide selection of screw sizes ensure maximum flexibility. The system is complemented by a numerous range of additional options from the DS screw program and integrable discharge aids – for customized solutions tailored to your needs.
Safety
Our dosing systems meet the highest safety standards. All moving parts are completely enclosed, the system is sealed and equipped with speed monitoring. It meets the requirements of the Machinery Directive (MRL), is ATEX-certified, and designed according to EHEDG standards. The use of food-grade oils and lubricants and compliance with Regulation (EC) 1935/2004 ensure safe operation even in sensitive environments.
Processes and applications
The precise solution for complex dosing tasks
The MacDos small component weighing system is used in various areas, particularly where several dry, powdered, and granular bulk materials need to be dosed in medium quantities and provided in batches. Here are some specific areas of application:
- Medium & large component dosing station with 2-8 hoppers and central hopper scale
- Discharge and dosing of corn flakes, chocolate chips, fruit pieces, and other sensitive ingredients in container mixers or scales
- Production of spice mixtures, baby/toddler food, cereals
- Provision of additives for rubber compounds
- Weighing of fillers and colorants for compounding
