Microwave are electromagnetic waves with frequencies ranging from 300MHz to 300GHz, and their direction and size change periodically with time. The process of microwave directly acting with the material to convert ultra-high frequency electromagnetic waves into heat energy is the microwave heating process. Water is a substance that strongly absorbs microwaves, the water molecules in the material are polar molecules, under the action of microwaves, its polarity orientation changes with the change of the external electromagnetic field, 915MHz microwave can make water molecules move 1.83 billion times per second, resulting in molecules are very friction, collision, so that the material heats and matures and a series of processes to achieve the purpose of microwave heating.
1. Fast heating.
Microwave heating is completely different with traditional heating mode.It makes heating medium become heater, do not need heat transfer process. Although thermal conductivity is poor materials, also can achieve heating temperature in a very short time.
2. Save energy,high efficiency.
Because materials contain water absorb microwave easily and fever, so in addition to a small amount of transmission loss outside, almost no other loss, high thermal efficiency, save energy.
3. Heating uniform.
No matter different shape of product, microwave heating all can make the object and evenly infiltration and electromagnetic wave list to produce the heat.So heating good uniformity, won't appear the endogenous phenomenon focal.
4. Mouldproof, sterilization, fresh.
Microwave heating has thermal and biological effect, can sterilize and mould proof in low temperature. Due to heating rapidly, the time is short, can maximum limit save material activity and the vitamin original colour and lustre and nutrition of food.
5. Advanced craft, control easily.
Microwave heating just have the basic conditions of electricity,and water if choose water cooling method, as long as control power, can realize microwave heating or terminate immediately, use microwave equipment can process automation control of heating process and heating process specification.
6. Covers less area, safety and harmless.
Because microwave can be controlled in made of metal heating indoor and wave, so microwave leak is few, no radiation hazards and harmful gases, do not produce the waste heat and dust pollution;Neither pollute food, also do not pollute the environment.
Microwave ready meal heating equipment ,fast food heating machine ,continuous ready meal heating machinery are suitable for heating ,low temperature sterilizing fast food ,widely used in industrial enterprise、school、fast food companies、restaurants、arena、exhibition and other fast food distribution.The advantages are :high productivity、continuous and fast ,can finish heating in 2 minutes ,don’t destroy the nutritional content of food ,don’t change color ,don’t change the flavor.At the same time,because in the microwave heating process,microwave thermal and non-thermal effect together,plays a bactericidal role for fast food,meets with the food health indicators requirements.
Microwave fast food heating equipment is the best choice for heating fast food.
Commercial microwave machine can be CUSTOMIZED according to your products productivity and worksite limitation.
