Microwave Puffing Machine Information
As a new technology of food manufacturing, microwave puffing technology is becoming widely used in the food industry, especially in the snack food sector. Microwave puffing machine makes microwave energy change into heat energy inside the matter, the water insider matter will absorb the heat energy to evaporate rapidly which forms a high pressure, the pressure inside the matter will force the matter to puff. The technology of puffing by microwave can preserve nutrition of food to a maximum extent and reduce processing time, and make the technologies of puffing and drying and sterilizing at the same time.
The Principle of Microwave Pigskin Puffing Machine
Microwave puffing technology makes the water molecule absorb the microwave energy through the radiation and conduction of electromagnetic energy, which makes the molecule move violently to gain kinetic energy. The gas temperature in the materials moves up sharply, when the rate of internal steam formation higher than the migration rate, the materials will appear vapor pressure gradient phenomenon. When the pressure goes beyond the bearing capacity of the organizational structure, the materials will be puffed quickly.
The heating time of microwave puffing technology is very short, which overcomes the oil content problem of the products. It’s the development direction of puffing technology, uniform heating, high thermal efficiency, good quality, easy operation, economic space occupation, energy saving, and environmental protection. Therefore, microwave puffing technology has a promising prospect.
