Machine vision equipment for sliced product inspection


Slice Inspector analyses any sliced food product, such as Serrano ham, York ham, sausages, cured meats, bacon, cheese, etc.

It is a quality inspection equipment designed to detect defects or anomalies in the slices. This inspection is carried out during the slicing process with the product normally frozen, before packaging. INSPECTRA’s patented high speed technology allows 100% inspection of the sliced product, having total control of the production and allowing the rejection of defective groups of slices.

The equipment analyses and detects defects in the slices (excess fat, oxidation, mould stains, blood, contamination, etc.) and sends a signal to the rejection system, for the separation of the defective clusters on a separate belt. In addition, it is capable of providing an analysis with ratios of different parameters related to the quality of the product.

Slice Inspector is a custom configured equipment for each customer and product. It can be integrated into any model of commercial slicer, and has advanced image processing software that allows images to be analysed at very high speed, extracting quality parameters according to the inspection needs and quality criteria established by each customer.

In addition, the equipment displays quality and production indicators in real time, sending reports and alarms automatically.

What are the advantages?

100% inspection of the slices, detecting defects after cutting and before stacking

Modular equipment with the possibility of adapting to customer needs

Suitable for any type of sliced food product

Can be integrated with any model of commercial slicer


  • Inspection of different quality parameters of the sliced product
  • Connection to existing rejection systems in the production line or to a new rejection system, depending on the customer’s requirements
  • Generation of quality indicators for inspected production
  • Production traceability, through images and data
  • Connection of the equipment in remote for visualization of data in real time
  • Simple and ergonomic interface, with the possibility of adapting to customer needs




The equipment incorporates advanced artificial vision techniques and image processing software. Its technology allows high resolution images to be processed at very high speed, giving the equipment great power and versatility for inspection in slicing processes. This high-speed vision technology allows images to be captured with the precise sharpness required to detect the most common defects in slices with a differentiated tone, using artificial vision, synchronising image capture according to the position of the blade in the cutting area.

Its main applications are aimed at detecting

  • Excess of fat: perimeter, central, overall and infiltrated
  • Presence of blood
  • Presence of oxidation or yellow grease 
  • Presence of mould 
  • Presence of contamination by foreign bodies 
  • No interleaver between slices (translucent film visible on the slice)

The high-intensity LED lighting system, together with the high-speed vision system, forms the image capture module.

This module is coupled to the slicing machine as a “plug-in”, being integrated in the mechanical protection bar or in the blade safety fairing itself, being compatible with most commercial models on the market.

This module is designed not to interfere with normal maintenance operations or blade changes. As regards watertightness, it has an IP69K degree of protection, the most demanding against the entry of water and dust.

The monitoring and control module consists of a touch screen and an electrical cabinet. Depending on the space available on the production line, it can be left on the floor (totem design), or some special adaptation can be made, depending on the location and ergonomics of the workplace.

The monitor can be rotated to turn left or right with respect to the cabinet, thus facilitating the operation of the equipment by the staff.
