Stevioside Microwave Drying Equipment
Stevia glycosides, also known as stevia sugar, are extracts from Stevia leaves that do not contain sugar or calories; The color ranges from white to slightly yellow, with a suitable taste and no odor, making it a promising new sugar source with broad development prospects. Stevioside is a sweetener that has been discovered worldwide and approved for use by the Chinese Ministry of Health. It has a natural low calorie value and is very similar to the taste of sucrose. It is the third natural sweetener with development value and health promotion, following sugarcane and beet sugar, and is internationally known as the "world's third sugar source".
The process of drying steviol glycosides requires a large amount of heat, and the drying process of steviol glycosides has a significant impact on product quality. Therefore, selecting suitable steviol glycoside drying equipment and optimizing the drying process of steviol glycosides are of great significance for improving the thermal efficiency of steviol glycoside drying, reducing the production cost of steviol glycosides, and ensuring product quality.
Microwave drying characteristics:
1. The drying temperature is low and uniform, resulting in a bright color of the product;
2. Selective heating. Because water molecules and alcohol absorb microwaves well, the parts with high water and alcohol content absorb more microwave power than the parts with lower water and alcohol content. This is the characteristic of selective heating, which can achieve uniform heating and uniform drying;
3. The direction of dry and dehydrated water vapor is from inside to outside. So, microwave drying has a puffing effect, which is very helpful for subsequent crushing;
4. Energy saving and efficient. Microwave directly acts on materials, so there is no additional heat loss. The air inside the furnace and the corresponding containers do not heat up, so the thermal efficiency is extremely high and the production environment is significantly improved. Compared with far-infrared heating, it can save 30% electricity.
5. Easy to control, advanced technology. Compared with conventional methods, the equipment is ready to use immediately upon startup; No thermal inertia, flexible and convenient operation; The microwave power is adjustable. In microwave heating and drying, there is no wastewater or exhaust gas, making it a safe and harmless high-tech. Improve product quality and bring economic benefits!
