Fries that are too short or too long… Measuring them accurately may sound straightforward, but achieving reliable length control and measurement in an industrial processing line is a real challenge. Fries overlap, form clusters, and travel continuously on moving conveyor belts, making it difficult to determine their actual length with confidence.<\/em><\/p>\n

This is where conventional measurement systems start to fall short. It’s time to move beyond traditional methods. Can artificial intelligence<\/strong> overcome these challenges? To find out, Optimum Sorting has integrated technology from AI partner Polysense<\/strong> into its software platform. These AI models can determine the true length of a fry far more accurately, even when fries overlap or are clustered together. The result is more reliable measurements, improved product quality, and greater efficiency throughout the sorting process.<\/em><\/p>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][nectar_animated_title heading_tag=”h4″ style=”color-strip-reveal” color=”Extra-Color-1″ text=”Key insights:”][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][nectar_icon_list animate=”true” color=”Extra-Color-1″ direction=”horizontal” columns=”1″ icon_size=”large” icon_style=”border”][nectar_icon_list_item icon_type=”numerical” text_full_html=”html” title=”List Item” id=”1791295190587-6″ tab_id=”1791295190588-6″]\n

The challenges of traditional length measurement<\/h3>\n

Conventional sorting systems evaluate products based on what their cameras can see in 2D. As soon as fries<\/a><\/strong><\/span> touch or overlap, there is a real risk of incorrect measurements. For example, a cluster of two overlapping fries is often interpreted as a single large fry. For processors supplying the retail or foodservice market with strict product specifications, these inaccuracies can become a real headache and create significant operational risks.<\/p>\n

In many cases, processors lack a complete and objective view<\/strong> of the actual length distribution within a batch. As a result, it becomes difficult to accurately assess whether the product mix meets the required specifications. Quality control<\/strong> also becomes more challenging. Without detailed insight into length distribution, it is difficult to objectively verify whether a batch fully complies with agreed quality standards and customer requirements.<\/p>\n

Inaccurate length measurements can also lead to unnecessary product loss<\/strong>. When too many long fries end up in a lower-value product mix, giveaway increases. Incorrect product classification may also result in fries being cut unnecessarily. The outcome is increased overprocessing, excessive product loss, and lower yields.<\/p>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][image_with_animation image_url=”12178″ image_size=”custom” animation_type=”entrance” animation=”Fade In From Bottom” animation_easing=”default” animation_movement_type=”transform_y” hover_animation=”none” alignment=”center” border_radius=”none” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default” custom_image_size=”850px”][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_column_text css=”” text_direction=”default”]\n

Three steps to smarter length control<\/h3>\n\n

To improve length control, Optimum Sorting developed the Sort-to-Length<\/strong> software module. In the future, this module will be further enhanced with advanced AI models developed by Polysense, a specialist in artificial intelligence for the food industry.<\/p>\n

The process is straightforward. First, the desired length distribution is defined based on customer requirements, product specifications, or end-market needs. AI then measures the length of each individual fry with a high degree of accuracy, even when products overlap or form clusters. This provides processors with a continuous and objective view of the actual length distribution, enabling better process control, more accurate grading, and data-driven sorting decisions.<\/p>\n[\/vc_column_text]

\"\" <\/div>
Define the specifications:<\/strong> Set the desired length parameters for each customer or production batch. This may include minimum length requirements, target ratios between short and long fries, or other product-specific criteria. <\/div>
<\/div><\/div>

Achieving 100% length control with AI<\/h3>\n\n

Thanks to advanced segmentation algorithms, AI can see beyond complex product clusters<\/strong>. Even when fries touch, overlap, or are grouped together on the conveyor belt, the system can accurately identify and analyse each individual fry. Instead of relying on approximations, processors gain a clear and reliable view of the true length distribution across 100% of the product stream. To achieve this, the AI performs several analyses:<\/p>\n[\/vc_column_text]

What does this mean for fry processors?<\/h3>\n\n
\n

Artificial intelligence brings a new level of precision to fry length control. By analysing every individual fry in the product stream, it provides a complete and unbiased view of the true length distribution. As a result, processors gain greater control over product quality, raw material utilisation, and grading performance. Rather than relying on sampling or manual inspections, operators have access to continuous data from the entire product flow. This makes deviations easier to detect and enables faster, more targeted process adjustments.<\/p>\n

The result is less product giveaway, reduced overprocessing, and a final product that consistently meets specification. The data also provides valuable insight into production performance, making it easier to compare yields, refine processing settings, and monitor line efficiency over time. In turn, quality control becomes more accurate, more predictable, and easier to manage.<\/p>\n<\/div>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” constrain_group_5=”yes” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” gradient_type=”default” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” enable_animation=”true” animation=”grow-in” animation_easing=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”default” gradient_type=”default”][vc_row_inner equal_height=”yes” column_margin=”none” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” text_align=”left” row_position=”default” row_position_tablet=”inherit” row_position_phone=”inherit” overflow=”visible” pointer_events=”all”][vc_column_inner top_padding_desktop=”10%” constrain_group_100=”yes” bottom_padding_desktop=”10%” left_padding_desktop=”10%” constrain_group_101=”yes” right_padding_desktop=”10%” top_padding_tablet=”64″ bottom_padding_tablet=”64″ left_padding_tablet=”5%” constrain_group_103=”yes” right_padding_tablet=”5%” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color=”#323a04″ background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” font_color=”#ffffff” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” overflow=”visible” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/3″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_color=”#efefef” column_border_style=”solid” column_padding_type=”advanced” gradient_type=”default”][nectar_icon icon_family=”iconsmind” icon_style=”default” icon_color_type=”color_scheme” icon_color=”white” icon_padding=”0px” pointer_events=”all” icon_iconsmind=”iconsmind-Magnifi-Glass22″][vc_column_text css=”” text_direction=”default”]\n
