Box lunch microwave heating equipment

Features of lunch box microwave heating equipment:

1. Even heating and fast speed

The general heating method relies on heating the surrounding environment to first heat the surface of the object by heat radiation or convection of hot air, and then conduct the inside of the object through heat conduction. This method has low efficiency and long heating time.

The characteristic of microwave heating is that the microwave is generated inside the object to be heated. The heat source comes from the inside of the object. The heating is even, and it will not cause the phenomenon of "outer coke and unripe inside", which is beneficial to improve product quality. "Heating" greatly shortens the heating time, and the heating efficiency is high, which is beneficial to increase the product output. The inertia of microwave heating is small, which can realize rapid control of temperature rise and fall, which is beneficial to automatic control of continuous production.

2. Selective heating

The heat generated by microwave heating is closely related to the loss of the heated object. The dielectric constant of various media is in the range of 0.0001 to 0.5, so the ability of various objects to absorb microwaves varies greatly. Generally speaking, a medium with a large dielectric constant is easy to be heated by microwave, and a medium with a too small dielectric constant is difficult to be heated by microwave. This is the characteristic of microwave selective heating of objects.
