Microwave Drying Equipment For Raisins

A string, a bunch, the shiny grape like black pearl and transmission of attractive color, can not help but make people salivate. Grapes are sweet, sour, and delicious. When dried, they become raisins. They also have a unique taste, and most of us like them, too. How are raisins dried? The raisins microwave drying equipment of Leader Microwave Equipment Company is the right choice.

Characteristics of microwave drying equipment for raisins

  1. Short drying time, low temperature and uniform of raisin microwave drying machine make raisins rich in flavor and bright in color.
  2. It is characterized by selective heating. Because water molecules are good at microwave absorption, the parts with high water content absorb more microwave power than those with low water content.Using this characteristic can achieve uniform heating and drying and sterilization thoroughly.
  3. The direction of dehydrated water and air is from the inside out, so theraisin microwave drying equipment can expand the raisins.
  4. Microwave is a direct action on the material, so there is no additional heat loss, compared with other ways of drying sterilization can save more than 30% of electricity.Raisin microwave drying machine only needs water and electricity, simple and convenient, no pollution, energy saving and environmental protection.
  5. Advanced technology, flexible and simple operation, the power of raisin microwave drying sterilization equipmentcan be adjusted from 0 to rated power, microwave intensity and temperature in the cavity can be adjusted, the monitoring system can display the temperature inside the wall, material process and so on. It only takes 2-3 people to dry and sterilize the raisins.
  6. Microwave equipmentcan also be used to sterilize raisins in bags or bottles. Microwave penetration, can penetrate plastic bags or glass bottles for sterilization, microwave sterilization speed, can be mass production, the packaging of raisins can be sold after drying sterilization, no secondary pollution.

Working principle of microwave drying equipment for raisins

Microwave drying is a new drying method. During drying, microwave can directly act on medium molecules to convert into heat energy. Due to its penetrating property, microwave can heat both inside and outside the medium at the same time without heat conduction, so the heating speed is very fast. For food with water content of less than 30%, the drying speed can be shortened by hundreds of times. At the same time, no matter what shape the object is, due to the same heating inside and outside of the medium of the object, the temperature difference between the inside and outside of the material is small, uniform heating, will not produce the phenomenon of internal unripe external coking in the conventional heating, greatly improving the drying quality. At the same time, microwave acts on bacteria and worm eggs to produce thermal effect and biological effect, blocking the metabolism of bacteria and other microorganisms to achieve the effect of killing worm eggs.
