Spirulina Sterilizing with Microwave Sterilizing Method

Online, May 23, 2013 (Newswire.com) - Spirulina is a good health care product with rich nutrition. Its protein is of 60%-70%, highly more than soybean, beef and eggs. The ectoderm of spirulina is very thin with 40-60μm, mainly made up by mu copolymer, which is easy to degenerate. After sterilized, the spirulina can be made into spirulina pills, spirulina powder and spirulina protein products. While traditional sterilizing method cannot meet the special requirement, microwave method is most ideal way which can extend the spirulina shelf life. At present, many companies have started to adopt microwave sterilizing method, they give us good feedback with perfect sterilizing effect.

Drying spirulina by low temperature within a very short time to keep the 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 Degree Celsius 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.

Microwave equipment for spirulina drying and sterilizing has incomparable superiorities.It is especially designed based on the spirulina's features of fine granularity and light weight. The microwave sterilizing is the result of combined action of the thermal effect and non-thermal effect. So the effect of sterilizing is double. When heat the spirulina it absorbs the microwave energy both inside and outside then the protein of bacteria coagulates and dies within a short time. The microwave high-frequency electric field changes the bacteria's membrane potential and structure then the protein of spirulina's bacteria mutate, lose viability and die. The bacteria within spirulina are killed evenly and thoroughly. It adopts enclosed screw conveyor when loading and discharging the spirulina material so that it could keep continuous operating and could not be polluted.

Azeus microwave spirulina sterilization equipment is mainly used for drying and sterilization of spirulina tablet, spirulina powder, spirulina protein powder, etc. Besides, this machine can also be use for sterilizing other protein powder and health care products.
