Online detection and packaging detection: after the completion of the single freezing machine, generally, frozen fruit and vegetables can be detected on plates or after packaging.

Metal detector: according to the efficiency of the single freezing machine, product effect of general frozen vegetables will not influence the detection accuracy.

X-ray inspection system : X-ray inspection systems have better detection performance when it comes to uneven frozen products. X-ray inspection system, with air-blowing rejecters, achieves progress in detecting stone and glass.

Checkweigher : the weight checking machine is widely used for weighing the products before entering into market. For example, the mixed frozen vegetable can be checked the weight at the end of the production line.
