Abstract
A cylindrical barrel with electromagnetic induction equipment, The electromagnetic induction heating method used in this invention has the following advantages in comparison with the existing heating methods: (1) being energy efficient, with heating efficiency of up to 90%, this is attributed to the direct heating which has not heat loss in transmission. And beyond the working time, the electricity in the standby mode is sufficient, this saves electrical power; (2) fast heating, able to reach the target temperature in seconds and increase the accuracy of temperature control; (3) partial heating enabled, as heating is controlled by the module at certain part; (4) consumption materials efficient, as it reduces the damages of heating belt or cable caused by the conventional method in which the temperature of the heating belt or heating cable must be higher than that of the barrel; (5) environment friendly, contributed by the low heat emission, this also saves the energy used by air-conditioning needed in the previous scenario.
Description
DISCRIPTION
1. TECHNOLOGY
The most commonly used heating method for barrels is as follows: heating belt or heating cable is used on the exterior of the barrel to produce heat energy which is directly transferred or eradiated onto the barrei until reaching the satisfactory temperature. The deficiencies of this heating method are: (1) the heating unit has low heat efficiency at approximately 70%; and (2) huge heat loss is occurred during the process of transmission or radiation, which results in low efficiency of the total usage of heat energy at about 35-60%; and (3) the temperature of the heating belt or cable must be higher than that of the barrel, which results in serious damages of the heating belt or cable.

2. FIELD OF INVENTION
This invention does not use the above-mentioned heating method in which a heating belt of heating cable is fitted on the barrel to produce heat energy; it adopts the eddy current generated by the electromagnetic induction coil cable directly on the barrel to produce heat.
The electricity is transformed into high-frequency current through the induction power generator (Exhibit 1) and transmitted onto the heating coil cable, the high-frequency current is transmitted through the coil cable and generates eddy current inside the metal barrel and thus produce heat for the barrel (Exhibit 1).
The induction power generator can be of one unit or more (Exhibit 2), depending on the specific length of the barrel and the requirement on the rate of power in heating. The use of multiple generators is helpful to ensure the temperature of the barrel in case of failure in one or more units.
