Rejector Systems

With over 50 years’ experience in the design and manufacture of inspection and detection equipment, we provide the best solutions that suit our customers' needs.


It is common to place a rejector system after an inspection system at the food facility for the below reasons.

1. Prevent the production downtime from stopping the line when the error occurs.

2. Prevent a careless mistake (put back defective products to the line) by an operator.


Flipper Type

選The most common type of rejector is the flipper. NG products are pushed aside by the rejector gates (arms). It is ideal for products in boxes and thick bags.

Air Jet Type

NG products are blown sideways off of the line by a powerful blast of air. It is ideal for small, lightweight packaged products at high speed.

Trip Type

In this unusual belt method, NG products are carried off either left or right by belts running crosswise to the product flow. It is suitable for rejecting large packaged products.

Pusher Type

NG products are pushed off the line sideways by the action of a gate attached to an air cylinder. It is suitable for rejecting products in packages and thick bags.

Turning Type

This method uses a turning gate to reject NG products. It is suitable for rejecting products in large packages and in thick bags at comparatively highspeed.

Carrier Type

NG products are sorted horizontally without any shock due to rejection. Since the rejection process doesn't cause any damage, it is ideal for fragile products.

Chute Type式

Rejected products fall when the chute is reversed. It is ideal for rejecting relatively light bulk products.
