For very high performance heat treatments, the extinguishing chamber can be used in combination with the vacuum furnaces for low pressure carburizing.
The quenching chambers can be used from 0 to 20 bar absolute and with temperatures up to 1250 ° C and are suitable for low pressure carburizing, quenching and tempering, solubilization and stress relief brazing, sintering, high temperature sinter hardening, etc.
Through the process control and the sensors placed inside the system, these autoclaves guarantee a high uniformity of treatment and absolute reproducibility, which guarantees absolute quality.

How Microwaves works:

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.

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.

The heated screw dryers exploit the transmission of heat by contact, where the coil and the jacket of the screw are heated by a fluid – usually diathermic oil or steam is preferred – and in counter current a light gaseous flow is made to flow (air or inert gas) which helps the stripping of the steam released during drying.

The heated coil, in addition to releasing energy to the material, makes it move forward and turn inside the casing so as to facilitate the mixing and advancement of the material. This type of dryer can also be internally polished. It can be washed and is suitable for the treatment of food products.

This technology allows you to dry up powdery or oxidation-sensitive products even at high temperatures.

The rotary kiln is a technology of drying, incineration or heat treatment of the material that has ancient origins, but is still used today in various sectors. The rotary kiln is composed of a cylinder that rolls on rollers driven by one or more gearmotors.
The motorization can be applied directly on the rollers or by means of racks placed on the cylinder body. Inside the kiln there are spirals or vanes that help the movement, lifting and spreading of the material inside the cylinder while rolling.

The materials used are many, from simple carbon steel, to stainless steel, special alloys resistant to temperature and corrosion and finally coating in non-stick or refractory material.

The heat can be transferred to the material with an energy flow in equi current or against current, depending on the direction. Hence here we can have a direct heat transmission through direct flame from the burner directly inside the oven or indirectly through air heat generated externally.

This technology is often used in difficult materials such as waste or especially in incineration, but the thermal performance of the system is not optimal, certainly for certain types of process it is preferable to use our other type of dryer, perhaps combining microwaves to increase even more thermal outputs.
