Many people like to eat fruit very much, fruit contains a lot of vitamins, can supplement the human body needs, among all fruits, grapes are very popular, of course, as people’s dietary requirements increased, grapes were also made into a variety of different delicacies, raisins is one of them. Raisins taste very good, and compared to grapes has another flavor. So how are raisins made? Leader Microwave Equipment Company’s raisin microwave drying equipment can effectively dry raisins.
Advantages of microwave drying equipment for raisins：
- High energy conversion efficiency, heating speed
The raisin microwave drying machine uses microwaves to dry, microwaves are applied directly to the raisins themselves, the microwave equipment itself does not heat, but the microwave energy can penetrate the raisins, causing polar molecules in the raisins to rub against each other and generate heat, so there is no energy loss and it dries very quickly.
- Uniform drying
The rapid heating effect of microwave makes the water molecules in the raisin evaporate quickly, and because the microwave of the raisin microwave dryer acts directly on the inside of the raisin, the inside and outside are drying at the same time, so the drying is very even.
- Low temperature sterilization, reduce nutrient loss
Microwave drying machine can not only dry raisins, but also can play the role of sterilization, microwave sterilization is carried out under the dual action of microwave thermal effect and non-thermal effect. Compared with conventional temperature sterilization, it can achieve satisfactory sterilization effect at a lower temperature and in a shorter time.
- Easy to use and operate
Microwave power and conveyor speed can be infinitely adjustable, no thermal inertia, can be opened and stopped instantly, so the microwave dryer is easy to control and operate.
- Clean and sanitation
The whole machine of microwave drying equipment is made of industrial grade stainless steel. The production process is clean and hygienic, and the secondary pollution is avoided.

Comparison between raisins microwave drying equipment and traditional drying method for raisins：
There are many traditional methods of drying, such as high temperature heating or natural drying. For raisins, these methods have many disadvantages. First of all, it takes a long time to dry, usually several days to complete the drying, and high temperature heating will make the nutrition loss of raisins, taste changes, natural drying will also make the health status of raisins can not be guaranteed. Using microwave drying equipment to produce raisins, not only good quality, rich nutrition, and very clean health.
With the rise of microwave technology, there are now more and more microwave equipment around us, such as frozen seafood microwave defrosting equipment, tea mushroom microwave drying equipment, mushroom microwave sterilization equipment, etc, are playing a very important role in our daily life.
Raisins produced by raisins microwave drying equipment are widely praised for their delicious taste and high nutrient content. When the opportunity comes to our side, we must firmly seize, believe that under the leadership of microwave equipment, our future will be brilliant!
