The principle of microwave drying and sterilization machihne:
Unlike other heating methods the dielectric heating can effect higher temperature inside the product than on its surface.
Due to the heating of the material throughout the whole volume the high uniformity of warming is reached as well as more precise temperature regulation. Overheating of certain parts (to the overcritical damaging temperature) of the product can be better prevented this way.
The products can be treated in the suitable packaging since the electromagnetic waves effect does not depend on the thermal conductivity and is not influenced by the external isolating layers.
Dielectric heating treatment improves the quality of the product resulting in competitive advantage and its higher salability.
Comparable efficiency of treatment or similar process solution is hardly achievable or even impossible by conventional heating method in many cases.
The defference normal drying machine with microwave drying and stterilization machine:
For many cases the rapid drying is far less important than the necessary condition of achieving it at relatively low temperatures (avoiding harm of the product).
Drying foods conventionally often degrades their thermosensible components (such as vitamins, essencesâ¦) â as well as deteriorates their organoleptic properties
For chemicals there is often necessary to take n to account parameters of flammability, explosiveness, or many undesirable changes. The process has to run keeping the under critical temperatures in the whole volume (such as flammable temperature, boiling temperature, sintering etc. Moreover certain dissolvents can be dried out at relatively low temperatures preventing the fire danger
Glues and paints can be dried out without harming the base material. Conventional methods often warm the material surface up to 180 Â°C while microwaves keep it down on 100Â°C or below. Moreover fast MW treating enables to avoid overdrying of surface layer and material damage.
The advantages of microwave drying and sterilization machine:
High energy efficiency
Water as extremely polar material absorbs efficiently the microwave energy converting it almost entirely to heat. In physical principle the comparable efficiency can be hardly achieved by any other method although using the conventional heat can be caused by other factors then the efficiency.Uniform and steady of the whole volume heating
From the components of the material usually the water molecules are most affected and on the contrary dry parts of the material is often MW transparent. This effect can be used for equalizing of the moisture level among the various parts of the material â in case of non uniform moisture spreading at the beginning of the processIt enables also pushing out the lawww.liquid component and autoregulation of the drying process.
Fast moisture transfer
Conventional drying of the solid state material often creates very dry layer on the surface â crust â breaking the capillary transfer of the moisture from the core. The dry crust can also insulate thermally the core of the material. Using the microwaves on the contrary avoids creating the crust since the moisture pushed from the core preserves the humid surface and supports the capillary.
