Machine vision equipment for slice inspection


Slice Inspector is a quality inspection system designed to detect defects in sliced food products. This inspection is performed during the slicing process with the frozen product, before packaging. The high-speed technology allows 100% inspection of the sliced product, having a total control of the production.

Slice Inspector not only detects defects in the slices such as thickness or amount of fat, detection of stains, location of areas of product degradation, absence of interleaver, slice breakage … but also provides the analysis of multiple parameters related to food quality as the percentage of different characteristics of products such as fat, additives or holes among others.

What are the advantages?

Slicing defect detection before stacking

Can be integrated with any slicer

Valid for any type of sliced food product

Capturing product quality parameters

Hygienic design and cleaning

SLICE INSPECTOR is designed to qualify for today’s standards of hygienic design. It is made of high quality stainless steel resistant to acids (A2 ISO), and prepared for the cleaning routines normally used in the food industry.

The image capture module has been designed with IP69K protection, and is prepared to work with high water pressure at high temperature and resist chemical abrasion from detergents.

All materials that may come into contact with food are removable for a better cleaning process and comply with food regulations.

Types of products analysed

It can analyse any type of sliced food product, such as Serrano ham, York, chorizo, salami, bacon, cheese, etc.

Before the packaging of the product is when the need to ensure quality control may arise. For this purpose, the system is capable of inspecting the front face of each slice, analyzing images of 100% of the production.

High-tech solution

SLICE INSPECTOR has been designed to work in a continuous production process line and is able to withstand the harsh conditions found in food industry processing lines.

The equipment processes the images in real time, by means of a powerful computer and software specifically designed to be able to execute the image processing algorithms with the minimum processor load.

The detection algorithms are designed to suit each product to be inspected and the structure of the equipment is adapted to different commercial slicing machines on the market, being integrated into the fairing of the same, and can act on the existing rejection system.




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

As for quality defects, the system detects them:

  • Excess fat: Central and subcutaneous, which allows the rejection parameters to be adjusted to the most demanding quality criteria.

  • Presence of blood, oxidation, mould and areas of different tone to the lean: for its parameterisation and validation, it will be necessary to have sufficient samples of defects in images captured directly in the slicer.

  • Absence of interleaver: This type of film must be translucent and its presence must be clearly visible on the slice.

The high-intensity LED lighting system together with the high-speed machine vision camera form the image capture module. This is attached to the slicing machine as a “plug-in”, being integrated into the mechanical protection bar or into the blade safety housing itself, and is compatible with most commercial slicing machines. This module is designed not to interfere with any routine maintenance or blade change.

The monitoring and control module consists of a touch screen and the electrical cabinet. Depending on the space available in the production line, the module can be left on the floor with its legs (“totem” design), or some special adaptation can be made. The monitor arm and its height can be made to measure, depending on the location and ergonomics of the workplace, as well as special anchoring to existing supports.

In the “totem” configuration, the monitor can be rotated to the left or right with respect to the cabinet, thus facilitating the operation of the equipment by personnel.

As for the interface that appears on the touch screen, it is designed to be very easy to use and is customized according to the customer. It is flexible enough to cover the needs of any type of production.
