Pork skin is a high protein source for meat by-product. The skin contains 2.5 times more protein, four times more carbohydrates and half as much fat. Generally speaking, the puffing of pig skin can be carried out through traditional frying, but the fat cost of Fried food is high, the oil content is high and the puffing quality is poor, which is not good for human health.
How do we puff pork skin without oil fry? YEMAI Industrial Microwave machine quickly puff the pork skin in a very short time. The puffed pork skin by microwave machine has a golden color with good tasty, microwave can also puff the pork skin which double or tripe the size of original raw pork skin. It could be nice flavor snack food with less labor cost.
Common puffing methods:
l Extruded expansion
Extruded expansion using mechanical friction, the material is strongly squeezed, stirred, sheared , into a paste shape, from the moment of ejection of the mold hole, in the role of a strong pressure difference, the water is vaporized, the material is expanded, forming a loose structure, porous, crispy expansion products, so as to achieve the purpose of extrusion.
With this swelling methods, the production cost and energy consumption are low,but the extrusion process parameters are difficult to control, the machine is not easy to clean, the product form is poor, high requirements on raw materials, mainly used for materials with high starch content, not for oil crops.
l Fried puffing
As the name suggests, fried puffing method increases the heat of food and destroys its original nutritional components. Long-term consumption of a large number of puffed food will result in a large intake of oil and heat, which is easy to cause the accumulation of human body fat.
Microwave machine used in the food puffing production, greatly change the traditional heat conduction process that from the surface to the interior. Compared with extruding and frying, microwave puffing can not easily cause some unnecessary chemical reactions, and does not increase the fat of food,keep the nutrition elements and original color, aroma and taste , improve the puffed food quality. It has the advantages of uniform heating, fast heating speed, high product quality, sensitive response, easy to control, high thermal efficiency, and small floor space etc advantages.Microwave puffing equipment is a good way to further process of snacks and obtain green food,which has very broad application prospects in the food industry .
Advantages of microwave puffing equipment:
1.The puffing speed is fast. The microwave oven does not heat the air etc, but the microwave energy directly act on the material, in which the polar molecules rub each other and produce internal heat, so that the internal liquid of processed material was heated and evaporated instantly , and then supercharged and expanded.
2.The microwave puffing machine has bactericidal effect. The thermal effect and non-thermal effect of microwave can effectively kill bacteria. The microwave puffing machine also have bactericidal function.
3.Snack microwave puffing machine is easy to operate.Microwave power and conveyor speed can be adjusted, there is no thermal inertia,open and close freely, product continuously .
4.Microwave snack puffing machine can improve the production environment. It has no heat radiation, no dust, no noise, no pollution, and meets the food hygiene inspection standards.
5.Microwave snack puffing machine has good puffing effect. The rapid heating effect of microwave makes the water molecules in the material vaporize quickly and achieves the purpose of puffing.
6.The microwave puffing equipment can reduce the loss of the nutrition components of the materials. The microwave puffing equipment has low temperature, short time, can maintain the nutrition components to the maximum extent, does not increase the oil of the food and not affect the original flavor, tastes very good.
7. Crispy snack microwave puffing equipment covers a small area, saving space and labor.
