Microwave Vacuum Drying for advanced Process Technology

Rapid and gentle Vacuum Drying for thermo sensitive Products with low thermal Conductivity

Introduction

Heat-drying has become important in almost all areas of industrial processing.

Apart from the popular conventionalprocedures based on conduction,convection, or infrared radiation, heat-drying utilising

microwave energy is an attractive solution to many problems in process technology.

In microwave drying, heat is generated by directly transforming the electromagnetic energy into kinetic molecular energy, thus theheat is generated deep

within the material to be dried. Especially in vacuum drying the fact of volume heating

gives an enormous importance in order to dry bulk and viscous products with low thermal conductivity.

Fields of Application for Microwave Vacuum Drying

•Pharmaceutical Industry

•Food Industry

•Chemical Industry of Fine Chemicals

•Semi-Conductor Manufacturing

Advantages

As compared to conventional drying methods, microwaves penetrate into much greater depths. This so-called volume

heating has the following advantages:

1. a temperature gradient directed towards the surface, i.e. temperatures inside are higher than on the outside giving rise to a higher partial pressure that drives the evaporating liquid to the

surface

2. consequently, the superficial layer does not dry out completely and the surfaces remain permeable

3. the liquid evaporating inside the product is emitted through the pore structure of the solid material’s macro-capillary system, resulting in a high drying velocity

4. the heating of water and most organic solvents occurs

selectively - due to the greater dielectric losses of water as compared to the product to be dried

5. swift and thorough drying of moist products with low thermal conductivity

6. stationary drying of thick layers without frictional losses

7. high total efficiency of energy application

8. high-speed control of the energy transport

9. short processing times, i.e. suitable for automated manufacturing

Together with the appropriate vacuum drying technology

the following advantages for the product are available:

1. Low drying temperatures treat the product gentle

2. No oxygen attack for the product

3. Highly nutritious instant properties

4. Better flavour

5. Less hydroscopic final product

6. Minimal product losses

7. Static drying of thick layers without fric

tional losses, therefore no mechanic stress for the products.

The microwave vacuum technology results in unique process technology giving the following benefits:

1. Local controlled energy zones with high controller speed

2. Defined and short residence times of the product to be dried

3. Cooling zone at the outlet for viscous products

4. Closed system

5. Simple setting of different plant operation modes for every product

6. Continuous operation mode possible

7. Short process times, high efficiency and full automated

guarantees an economic operation

8. Service friendly because of modular system and

full-automated cleaning
