Microwaves are a form of electromagnetic energy with frequencies between 300 MHz and 300 GHz, generated by the magnetron under the joint force of magnetic and electric fields perpendicular to each other. In the electromagnetic spectrum they are identified between radio waves and optical waves. The most common frequency used for industrial purposes is 2450 MHz, due to the advantages offered by this frequency. Microwave fields are reflected by metals, which do not heat up. For this reason, metals are used as conduits for microwaves, or wave guides and as walls for the microwave oven.

Since industrial equipment is made of stainless steel, the chamber acts as insulation for microwaves by reflecting them. Microwaves penetrate materials and release their energy in the form of heat as polar molecules (those with positive and negative ends – such as water) vibrate at a high frequency to align with the frequency of the microwave field (2.45 GHz).

This vibration generates heat. Many studies have now been published showing no difference in the stability and physicochemical properties of materials dried with microwave processing, when compared to other drying methods. Since microwaves are non-ionizing and do not have an amount of energy necessary for the formation of free radicals, there are no conditions created during microwave drying that generate product instability.

This characteristic can greatly accelerate the drying of the material, which is why our dryers are so efficient and advantageous in terms of low energy consumption.

Vacuum drying or evaporation is a process where the materials are dried with the help of a negative pressure compared to the ambient pressure. This depression is generated by a vacuum pump connected to the system.

Vacuum has the advantage of lowering the evaporation point of substances, so drying can be performed at a lower temperature than normal dryers.

This feature is very advantageous compared to traditional drying and can be applied on thermo-sensitive materials, thus preserving their integrity which otherwise would fail with a classic drying.

The vacuum drying system is also advantageous in terms of energy consumption, as lowering the evaporation point of the substances also translates into considerable energy and financial savings.

Mechanical stirrers are used in chemical or mixing reactions to mix various types of fluids or solids / powders.
The stirrers homogenize the reaction and the process outcome.
To complete the function of the stirrers, special breakwaters, heat exchangers or heated shafts can be integrated into the tank to increase the exchange surface.

SMC designs and builds reactors and stirrers within a wide range of industrial chemical plants. Mechanical stirrers are also equipped with vortex breakers, or baffles, in order not to hinder perfect mixing.
The mechanical stirrers are equipped with internal coils for cooling the mixture obtained by preventing the formation of hot spots, or points where the temperature can reach critical levels beyond which there may be safety problems to the entire system.
