Donut Microwave Puffing Equipment

Donuts are a popular dessert nowadays, sold in many pastry shops or fast food restaurants. From children as young as five to people as old as 75, people all love it. In daily life, donuts are mainly served as snacks. Some people also eat donuts as their breakfast staple. It is indeed a delicious food that caters to the taste of the public.

Sweet Buns

There are various kinds of donuts in the market, which are good-looking, crisp and tender tastes, sweet and delicious. Microwave puffing equipment is used in the manufacture of donuts. Leader Microwave Equipment Company’s doughnut microwave puffing equipment is a good choice, compared with other equipment, has many advantages.

Advantages of doughnut microwave puffing equipment

  1. The doughnut microwave puffing machinecan be heated rapidly and evenly under the direct action of microwave electromagnetic field without heat conduction. Health, high efficiency, puffing effect is better than conventional process.
  2. High heating quality, less nutritional damage, donut microwave puffing machinecan maximize the color, aroma, taste of food, reduce the destruction of the effective ingredients in food.
  3. It has bactericidal effect under the dual action of thermal effect and non-thermal effect of microwave. Compared with traditional technology, microwave equipmenthas a good production environment without thermal inertia. The product is crisp and refreshing, with rich fragrance, high swelling rate and natural color.
  4. Safe, hygienic and pollution-free, donut microwave puffingequipment has a strong sterilization ability for food, because microwave can be controlled in the metal heating room and waveguide work, so microwave leakage is effectively suppressed, no radiation hazards and harmful gas emissions, no waste heat and dust pollution. It doesn’t pollute the food or the environment.

Working principle of doughnut microwave puffing equipment

Microwave puffing equipment is a new type of atmospheric pressure puffing equipment which uses microwave radiation heating to vaporize the water in the material, thus driving the puffing of food material tissue. Microwave heating speed is fast, the gas (air) temperature inside the material rises sharply, due to the slow mass transfer rate, the heated gas is in a high pressure state; And there is a tendency to expand, when a certain pressure, material will occur expansion. The material of high moisture content, moisture evaporate substantially at the beginning of drying, make product surface temperature drops, when moisture is lower than 20%, because of the viscosity of material increases, cause the moisture in material interior interstitial and air are more difficult to discharge and be in high accumulation condition, can produce good puffing effect thereby.

With the development of microwave technology, a variety of microwave devices have emerged. Leader Microwave Equipment Company’s doughnut microwave expansion equipment, rice wine microwave sterilization equipment, fiberboard microwave drying equipment has been well developed, compared with other equipment, can better meet the needs of the major processing plants, is an advanced equipment, worth having!
