Automated taring line

16 June 2017

Tolsma-Grisnich has developed a taring installation for a major potato processor in Asia. This advanced automated taring line offers several methods for ensuring optimal quality during potato batch intake. Among other functionalities, the taring line includes the following components.

Salt basin
Potatoes referred to as ‘floaters’ are detected in this basin. Floating potatoes have a low underwater weight and are not fit for processing into fries.

Inspection table
During the sorting process, the batch is manually checked on this inspection table for rotten, deformed, green and torn potatoes.

MR06 grading machine
This custom-built grading machine ensures that the batch is divided into four size ranges and graded for length. Thus, the size-wise composition of the batch is established.

Establishing length for fry size
Finally, the length of potatoes is established by means of a scanner and matched against the length size that is applied for transforming potatoes into fries.

Automatically generated taring report
The weight of all substandard potatoes, such as green potatoes, floaters and undersize potatoes is automatically established. The taring report presents a well-organised overview of batch quality. The most important benefit for the potato processor is that final potato product processing quality can be assured thanks to this procedure.
