Steamed bread slice ( biscuits ) Microwave production technology
Steamed bread slice is China , Shanxi , Inner Mongolia and other northwestern regions as a specialty food , which is based on wheat flour , grains and powder as the main raw material production, with a variety of flavors , taste crispy , nutrient rich features . As people's living standards improve , people's diet requirements are also rising , and this traditional food crispy bun film is emerging as a casual fast food, fully meet the Chinese consumers' eating habits, gradually many consumer acceptance and recognition, market prospects are very broad. And the product as a green bound to replace some or all fried , puffed food ( biscuits, instant noodles , etc. ) , to become a favorite of many consumers .
Microwave frequencies from 300MHz ~ 300GMHz are electromagnetic waves , the direction and size of the periodically changing . Microwave and materials directly , ultra high frequency electromagnetic wave is converted into heat in the process of microwave heating process .
Water is a strong microwave absorbing materials , materials in the water molecules are polar molecules under microwave irradiation , the external electromagnetic field with the polarity orientation changes, resulting in a sharp molecular friction , collision , to produce heating and puffing the material and a series of microwave heating and drying process to achieve the goal . Its advantages:
1, the heat quickly and evenly
Microwave heating without heat conduction process , it can instantly penetrate into the material to be heated , the penetration depth of up to a few centimeters , or even a dozen centimeters , seconds to minutes will be able to convert the microwave to heat . Selective microwave heating, the heat more evenly.
2 , energy efficient
Because the material contains moisture and heat easily absorb microwave and therefore , in addition to a small amount of transmission loss has almost no other losses. Infrared heating and microwave heating as compared to the energy saving 1/ 3 to 1 /2.
3 , mold sterilization, does not destroy the nutritional content of the material
Microwave heating with thermal effects and biological effects , therefore, can at lower temperatures to kill mold and bacteria ; conventional heating heating time is longer , resulting in a large loss of nutrients , and the rapid microwave heating , to maximize the preservation of materials activity and food nutrients.
4 , advanced technology , continuous production
Controlling the microwave power can be realized as long as the heating or terminated. It has the perfect delivery system to ensure continuous production, labor-saving .
5 , safe
Microwaves are controlled heating chamber made ​​of metal working , microwave leakage is effectively suppressed , there is no radiation hazard and harmful gas emissions , does not produce heat and dust pollution.
Stage baking crispy bun film is mostly thermal oil heating equipment, resulting in investment in plant equipment is relatively large increase in both power consumption and also coal , resulting in high energy consumption and environmental pollution , poor sanitation , the operation is more complex, requires a lot of manpower. And our research and development of microwave baked crispy bread slice process method , not only to overcome the disadvantages of the above equipment , especially in the aspect of steamed taste quality of the film is a qualitative leap.
Sumo film production process : steamed bun → → once baked sliced ​​slinger → → → sprinkle baking secondary packaging material →
Steamed bread slice in a baking process the microwave output power 30KW, secondary baking microwave output power of 10KW ( 10KW optional infrared baking ) , to further improve the steamed bread slice color. Total length of about 18 meters , width of 1.5 meters , with a total height of about 1.7 meters , Nissan 3 tons , general food companies are suitable for use. Equipment made ​​of stainless steel , fully in line with food hygiene standards , no pollution , energy consumption in equipment , microwave equipment working Chief consumes about 65KW, throwing oil machine power 5KW, 10KW plus infrared , the entire device input power of about 75KW, the sets of equipment total investment of about 30 million, while conducting oil baking lines to Nissan 3 tons , for example, excluding coal consumption, power consumption is only the power of 40kW, by contrast , microwave production line on the obvious advantages .
The use of high-tech products to transform the traditional food processing is our food business enterprise development direction , microwave heating, microwave sterilization technology in food industry applications, the majority of enterprises are increasingly being recognized .
