Description of microwave drying machine:
The effect of microwave drying is closely related to the electrical
properties of the material being heated. P is proportional to the
product of the dielectric constant ε' and the loss tangent t nδ of
the medium. The ε' of each substance is different, but in addition
to the high water content material and some "ferroelectric"
substances, the ε' of the medium is between 1 and 10. The water ε'
is particularly large, 78.54. Therefore, the higher the water
content, the better the performance of the microwave. Based on
this, the general microwave source should be installed at the
entrance of the material.
It is widely used for:
This equipment are widely used for drying and sterilizing
powder,granular,flakes or colloidal form.
Applicable for instant noodles, rice ,noodles and other convenience
food,beef jerky, minced meat, fish, soy products, and other snack
foods and dehydrated vegetables, mushroom,mountain vegetables,
nuts,curing drying and sterilization.
Advantages :
This is the biggest feature of microwave heating. Whether it is
conduction, convection, or radiation, the heat source is external.
The temperature rise of the material is from outside and inside:
the surface is heated and then conducted to the inside, which is
subject to Fourier's law. Restrictions, usually the material that
is heated is a poor conductor with a large thermal resistance, and
the heating time is naturally long. The heat of microwave heating
is generated inside the material to be heated, so that the inside
and outside of the heat, not only the temperature is very uniform,
but also does not bring the phenomenon of sandwiching.
During conventional heating, the temperature surface is high and
the interior is low. This temperature distribution is not conducive
to rapid evaporation of water. The microwave heating is heated
together inside and outside, and because the surface is easy to
dissipate heat, the internal temperature is higher than the
direction of the external temperature gradient and the direction of
the water gradient is the same in the same heat transfer and mass
transfer direction, prompting the internal water to evaporate
rapidly, forming an internal pressure gradient. The moisture is
quickly diffused to the surface to evaporate, which greatly
shortens the drying time.
