The history of food automation: from steam-powered mills to soil sensors

18-19th Century: food production is entirely manual. Olives are pressed, fish is salted and grain is milled by hand. 

The invention of tin in the early 1800s.

This enables food preservation at scale and creating demand for mechanised filling and sealing equipment. The precursor to the modern production line starts in meatpacking sector. 

Early–mid 20th Century

The meatpacking assembly line concept is adopted into car manufacturing by Henry Ford.

Meatpacking plants became early exemplars, with "disassembly lines" that divid labour and use conveyor belts to move carcasses.

Bakeries, breweries and dairies invest heavily in continuous-flow machinery. Automatic bread slicers, pasteurisers and bottling lines became standard.

Refrigeration technology automates the preservation process, removing the reliance on ice harvesting or salting.

1950s-1970s

The post-WWII boom brings frozen foods, TV dinners and a consumer culture that demands consistent, standardised products at scale. 

Canning lines become capable of processing thousands of units per hour. Chemical and food science advances allow more products to be made by machine with longer shelf lives.

Individually quick frozen (IQF) technology is invented and there is investment in automated mixing, portioning and packaging equipment.

1980s-1990s

Machines can now be programmed for different recipes, adjust parameters in real time, and track production data.

Sensors enable automated quality control — detecting fill levels, checking weights and scanning for contamination.

HACCP (Hazard Analysis Critical Control Points) frameworks, increasingly mandated by regulation, are made feasible at scale precisely because of automated monitoring.

The introduction of programmable logic controllers (PLCs) and early computer systems transforms food factories.

Barcoding and traceability systems make their first appearance. 

2000-2010s

Robotic arms began picking, placing, and packing products, dealing with the challenge of handling fragile or irregularly shaped items like baked goods, fresh produce, and meat.

Machine vision systems enable automated inspection for defects, foreign objects and label accuracy.

Industrial robots — initially borrowed from automotive manufacturing — are finally adapted for food handling.

Collaborative robots are designed to work safely alongside human workers.

Automated guided vehicles (AGVs) begin replacing forklifts in warehouses.

2010s-present

The latest wave is driven by artificial intelligence, the Internet of Things (IoT) and big data.

Smart sensors throughout the supply chain — from farm to fork — feed data into centralised systems that can predict equipment failures, optimise energy use and adjust processes dynamically.

AI-powered vision systems detect quality issues that human inspectors could miss.

Fully automated facilities with no human workers on the floor – known as dark factories — become reality in beverages and confectionery.

In agri-food automation, autonomous tractors, drone crop monitoring and robotic fruit pickers are extending automation to primary production.

3D food printing opens experimental possibilities for customised food shapes and nutrition profiles.
