Seven steps to choose a high-power induction cooker with stable configuration
1, microcomputer processing chip and 8-bit analog chip
Affinity microcomputer processing chip has fast response speed, and a considerable number of components such as resistors and capacitors are replaced by digital programs, which greatly reduces the overall failure rate of induction cooker. 30 functional protections to ensure the stability and longevity of commercial induction cooker, with an average service life of 8~ 10 years.
Due to the limited storage space of 8-bit chips and the increase of peripheral devices, many protection programs cannot be written, and due to the delay of analog chips, protection programs cannot be protected in time, which directly causes hardware damage. The service life of commercial stoves is 1~2 years.
2. Full bridge scheme and half bridge scheme
The full-bridge scheme, the highest scheme of two imported Infineon IGBT and electromagnetic induction heating, requires more detailed procedures and engineers' experience. Very few companies really master this technology. The hardware configuration of full-bridge scheme is twice as expensive as that of half-bridge, and the average life of high-power cauldron is 8~ 10 years.
The applicable power range of the half-bridge scheme is 2.5KW~ 15KW, but the stability of the cauldron above 20 kW is poor, and its service life is 1~3 months.
3. Imported modules and domestic modules
Imported Infineon IGBT module, imported components, German process quality, long service life;
Domestic module materials have low cost, unstable technology and short service life;
4. 1.5mm thick integral bending panel and ordinary 1.0mm thick panel.
Affinity induction cooker manufacturer 1.5mm thickened integrated curved panel, waterproof and oil-proof.
1.0mm, panel variability, water leakage, high maintenance failure rate;
5, double duct patent
Patented double air duct, the heat dissipation of the movement and coil does not affect each other, which ensures that the cooking stove works continuously for 24 hours, with heat dissipation and ventilation, stable work and durability.
6. Durable pure copper wire coils and ordinary aluminum wire coils: pure copper in an affinity commercial electromagnetic cauldron and uniformly distributed wire coils; High-quality pure copper wire coil, achieving uniform throwing and heating effect.
Uneven coils such as aluminum not only have high maintenance cost and uneven heating, but also are semi-cooked.
7. Do you use a coil bracket?
Affinity commercial induction cooker coil bracket
Ordinary manufacturers have no brackets for binding ropes.
Commercial induction cooker coil bracket function:
1, to prevent the coil from expanding with heat and contracting with cold, resulting in uneven heating and local fire;
2. It is convenient for secondary maintenance and disassembly.
During the handling and operation of commercial induction cooker, the coil will move or deform, and the rope will age and break, resulting in half-cooked cooking, low thermal efficiency utilization, serious burning of the coil and pot, and high maintenance cost of accessories.
Second, do commercial induction cooker manufacturers have excellent electromagnetic heating technology and R&D strength (which is more technical, the products produced by manufacturers who specialize in electromagnetic heating products or those produced by manufacturers who change to electromagnetic heating products halfway? Which is more secure? )。
Third, the strictness of the quality monitoring of each commercial induction cooker by the original factory in commercial induction cooker before leaving the factory (if there are two commercial induction cooker, one of the commercial induction cookers successfully passed 48 inspections and passed the simulated kitchen test for three consecutive days before leaving the factory; The other one only passed three or four rough tests, and was packaged and delivered after being electrified in the workshop for 5- 10 minutes before leaving the factory. Which quality assurance is better? According to statistics, 90% of problems can be detected before leaving the factory, and problems can be solved in the factory in advance to prevent problems before they happen.
