Microwave heating systems

The design of our customer-specific microwave heating layers is based in particular on the many years of experience of our employees and is carried out by well-founded and realistic simulations based on highly competent physicists and high-frequency engineers.

Therefore, they are characterized by very high field homogeneity and gentle power density matched to the respective product! The globally successful projects are convincing proof of the sustainable quality and innovative power of our groundbreaking ideas, visions and decisions.

The name Fricke und Mallah Microwave Technology GmbH stands for modern and sustainable solutions in microwave heating.

About us

The Fricke und Mallah Microwave Technology GmbH was founded in 1995 by Dr.-Ing. Dirk-H. Fricke and Dipl.-Ing. Marcel Mallah.

Dr.-Ing. Dirk-H. Fricke studied electrical and high frequency engineering at the university Hanover. Then for five years he was scientific assistant at the Institut for Electroheat at the same university. He managed several microwave research projects of the AIF and BMFT.

Dipl.-Ing. Marcel Mallah studied electrical and high frequency enginneering at the university Brunswick. After this he works for three years in the german oven industry. There he developed several innovative microwave oven concepts.

The Fricke and Mallah GmbH is with 28 employees one of the leading german suppliers of microwave ovens for industry and research.

COSTPANO®

For the pasteurization of these trays so far the perforation of the film and the use of a check valve were essential to avoid bursting of the trays due to the overpressure. The innovative and groundbreaking COSTPANO® process marks the beginning of a new era in the heat treatment of foods using microwaves. The worldwide patented COSTPANO® process eliminates the overpressure in the tray, eliminating the need for both the hole and the valve in the sealing foil. In addition, COSTPANO® sets up very homogeneous temperature fields in the trays or application rooms with a time-linear increase, which enables energy-saving, gentle and aromatic cooking.

Key Features
With this heating method, the overpressure in the menu tray is avoided, which excludes the danger of explosions and deformations of the menu trays.

• No hole or valve required
• No steam escapes, which saves a considerable amount of energy
• No odour formation
• No addition of water during cooking results in aromatic cooking
• Substantial increased homogeneity
• Linear temperature increase, enabiling easily processing (automatic temperature control)
• 2D selectivity: Different heating rates per tray cavity
• International Patent and Registered Trademark - only available at Fricke und Mallah
• Certified process by internationally respected research institute in the field of food technology

Rapid Heating with Microwave plasma

Microwave plasma technology is a very demanding application used to activate surfaces in electrical engineering, automotive, textile and many other industries.

Fricke and Mallah and Heuermann HF-Technik GmbH develop microwave plasma sources with a excellent heat coupling. The result is a particularly high plasma density and high temperature processes of up to 5,000 °C. This field is generated by our microwave generator with 2.45 MHz and 3 kW output power.

The plasma jet reaches lengths of up to 10 cm. This is a unique result in this range. More Details

Solid State Microwave Generator

We would like to introduce our new Solid State Microwave (SSMW) Generator.

The advantages of the SSMW generator are obvious, no more Magnetron is required and the generator can adjust the required energy automatically. It is also possible for an infinitely variable regulation to 500 W in the manual mode. In future a regulation up to 1 kW will be possible. The generator supervises independently the reflection and switches off itself when reflection is too high. The construction method has been held consciously very compact to do justice to the rising claims of our customers.

The SSMW generator has 2 different modes, in the Continuous Wave (CW) mode the microwave is generated as had and reaches therefore a good homogeneity. In the pulse mode (Trigger) many short waves one after the other are generated what leads to a still better homogeneity and a lower temperature in the generator.
