Perfect preparation of food ingredients and raw materials

Mehl

Each cereal and cereal by-product has its own special characteristics for use. The food industry is constantly developing new applications and, at the same time, adopting consumer trends in the process. This results in a continuous stream of new forms for processing raw materials. Special attention must be paid to every technical detail right from the start of the process chain in order to be able to manufacture the best possible products in the future. Grinding with hammer mills plays a special role here. The structure and fineness of the grain obtained with the hammer mill are of crucial importance for achieving the desired qualities in terms of taste, appearance, and texture. In addition, nutritionally crucial ingredients must be distributed homogeneously in the product. The requirements for individual raw materials and products can vary greatly.

We have experience in the further processing of

    • vegetables such as beans and peas
    • dried fruits
    • herbs and spices
    • grains such as oats and spelt
    • pasta

 

Over 60 years of experience

Grinding solutions for food production Over 60 years of experience

Gentle grinding on the one hand and safe grinding on the other are essential when it comes to grinding cereals and intermediate products in the food industry. A high protein and fat content often poses a particular challenge in terms of the grinding process. Pneumatic conveying and gravity conveying lines are also important. The systems and system components must be made of steel or stainless steel, depending on the products to be ground.

The LDE high-speed mill can be used for fine grinding of food products. The special design of the 6-shaft rotor provides an ideal hammer configuration and ensures maximum contact with the material for the best quality. The simple and quick sieve change while the mill is still running means that the product can be changed very quickly or that the grain structure can be adjusted very quickly as the properties of natural products change.

Specifically designed for efficient grinding for challenging recipes and products: The special 6-axis rotor design plus optimized beater configuration in combination with high beater tip speed guarantees maximum material contact for the efficient production of the finest feed as well as coarser products.

The VL hammer mill is the universal mill for coarse grinding in animal feed, as well as for fine grinding in the production of pet food and fish feed. Other areas of application for this versatile mill include the grinding of chemical components, salts, spices, and natural products such as wood.

We are able to offer the right grinding module for every application and mill type, always taking into account the product properties, the available space in the facility and explosion protection. The grinding module with mechanical auger enables the components to be arranged compactly in a very small space.

If your system is designed in such a way that flour is required at a distant point, pneumatic transport is the method of choice. It should be noted that the mill must be decoupled from the general separator. We offer our customers this solution approach.

For greater efficiency in the food sector

The efficiency of each grinding system is not only determined by the technical design of the mill, but also by the distribution of the raw material across the entire width of the mill. Together with the gravity separator and the suction air flow, the dosing device ensures uniform product distribution. We can offer you a wide range of feeding solutions.

The AGS air-gravity separator is suitable for the continuous separation of foreign objects from bulk materials. Dosing takes place in combination with a rotary dosing valve, which can also transport non-free-flowing bulk materials such as flour in bridge conveyor lines. Side doors and retractable magnets, as well as foreign object collection trays, ensure easy cleaning.

The rotary valve safely decouples the raw material and feeds it into the grinding module. A metering screw can also be used as an alternative. Hygiene must always be taken into account here, as the probability of transfer is higher during product changes. Rotary dosing valves with reduced cells are used for certain products to prevent the mill load from varying.
