The invention belongs to the technical field of veratraldehyde processing, and discloses a novel veratraldehyde processing method and processing system. The novel veratraldehyde processing system comprises: a video monitoring device, a temperature detecting device, a PH detecting device, a main control device, a raw material weighing device, a mixing and stirring device, a heating device, a cooling device, an extraction device, a crystallization device, a drying device and a display device; and the invention discloses a novel veratraldehyde processing method at the same time. According to thenovel veratraldehyde processing method and processing system disclosed by the invention, the veratraldehyde processing is simple and convenient, environmentally friendly and pollution-free, the deviceinvestment is low, the purity is high, the operation is convenient, and the prepared veratraldehyde has a good use effect and is safe and reliable; meanwhile, the purity of vanillin and the product quality are effectively improved by using a semiconductor photocatalyst via a vanillin preparation method; and by adopting a methylbenzene preparation method, the purity is high, and the extraction efficiency in a veratraldehyde processing process is greatly improved.
