Drying Spirulina by Low Temperature within Short Time to Keep good Quality
The spirulina contains protein content, chlorophyll, phycocyanin, polysaccharide as well as vitamins A, B, and a small amount of fat composition so it must be dried at the temperature of less than 84 Celsius degree otherwise the active ingredient will be destroyed and the quality will be affected. And the cell membrane of spirulina is thin and has good permeability so it has to be dried within a short time in order to keep the quality. However the traditional drying methods such as baking and radiation affect the quality. By the microwave drying method the water molecules of spirulina motion reciprocally with high-speed in accordance with the frequency of the microwave, extrude and make friction to generate heat so that the moisture within the spirulina can be vaporized and dried. And when dry the spirulina by microwave, it absorbs the microwave energy from all directions both inside and outside without the thermal conduction so it can be dried within a very short time by a low temperature.
Features of microwave drying machine
1.Fast heating speed: directly heat on the internal and external of material at the same time, do not need to preheat. While there must be a preheating process in the traditional production
2. Heating evenly: microwave drying is completed through electromagnetic waves produced by magnetron.The internal and
external of material will be heated at the same time .
3. Less nutrition loss: material just stay in the microwave heating box for a short time, and do not need air and steam to
conduct heat, therefore can maximize keep nutrients in the material.
4. Sterilization and alcoholization:The microwave drying equipment also have sterilizing and alcoholizing function.
5. Reduce the labor intensity, improve work efficiency
6. Friendly environment equipment
7.PLC automatic control can realize the data storage, output, printing. 8.Using non-contact infrared temperature measurement technology, high precision, simple control. 9.Compliance with national GMP certification requirements.
Application ofMicrowave dying machine
high moisture sticky materials;
Powder, granule, sheet, plate, strip, such as pieces of small billet material drying;
activation of catalyst regeneration;
sludge of solid wastes, such as drying, sterilization and disinfection
food, medicine, pharmaceutical raw materials of drying, sterilization and disinfection;
Rice, flour, dry, insecticidal, mouldproof treatment;Polymer curing;Foaming material of heat treatment.
1.The machine set up separate total control cabinet, PLC programmable control, human-machine interface display.
In the heater outlet equipped with infrared radiation temperature measuring probe, measuring surface temperature of material, through the thermometer display material temperature in time, to monitor this case point temperature materials
in a timely manner, and can set any temperature, according to the required temperature, lower limit setting can automatically
adjust the heating tempe.
2.Microwave from the top heater feed into the mouth, heated material can be directly to microwave energy, the loss is smaller
than other factory, heating efficiency is about 15% higher, the material heating uniformity is more than 20% higher.
3.The core component of this equipment‘s main electronic components used in microwave generator with high quality, long life, high reliability and work continuously.
