Principle of operation
Adopting hot air flow technology, batch roasting, roasting time is short, which can be reduced by half compared with traditional equipment; The advanced foreign technology is introduced for manufacturing, so that the equipment energy consumption is low, the roasting temperature is more uniform, the temperature curve setting and automatic control are realized, and the operation stability is very high; Double-layer frame structure is adopted for thermal insulation, which has good thermal insulation effect, and the external surface temperature does not exceed the ambient temperature +20℃.
Equipment introduction
The whole device consists of a material placing tray, a box, a heating circulation system and an electrical control system.
The insulation material is selected according to different use temperatures, and the manual door or automatic door is designed according to different discharging time.
The whole equipment is equipped with a set of control system, and the control mode is PLC+ touch screen. The main control functions are as follows:
(1) Setting and automatic control of heating curve
(2) Heating temperature setting and control, display
(3) Circulating fan control, variable frequency speed regulation
(4) heating and circulating fan interlock
(5) Over-temperature alarm (when the set temperature is +10℃ or lower, the set temperature is -10℃ and the alarm is audible and visual).
(6) Fault alarm
