The History of Mechanization in Tomato Paste Production

The mechanization of tomato paste production traces back to the early 20th century, as industrial food processing evolved to meet rising urban demand and reduce food waste. Initially, tomato processing was entirely manual—harvesting, washing, peeling, and cooking were labor-intensive and inconsistent, often leading to contamination and product loss. The shift began with basic mechanized tools like tomato crushers and hand-cranked pulpers.

By the 1920s and 1930s, mechanical pulping machines capable of efficiently separating seeds and skins became common, laying the foundation for large-scale processing. This period also saw the introduction of steam blanchers and mechanical peelers, which improved throughput and sanitation. In the 1950s, the adoption of vacuum evaporators marked a significant breakthrough. These systems removed moisture at lower temperatures, concentrating the paste while preserving its bright color, flavor, and nutritional content.

The 1970s to 1990s witnessed a digital revolution in processing. Automated sensors, programmable logic controllers (PLCs), and computer-aided manufacturing enabled real-time monitoring of temperature, viscosity, pH, and Brix levels (a key measure of sugar concentration). These technologies ensured consistent product quality and reduced waste. Modern advancements include robotic arms for material handling, optical sorters for defect detection, and aseptic filling systems that extend shelf life without preservatives.

Today, cutting-edge facilities utilize AI-driven analytics to optimize every stage of production—from harvest scheduling to batch formulation. Mechanized harvesting, especially with hybrid tomato cultivars bred for durability, allows round-the-clock operations. Global producers in the U.S., China, and Italy now process thousands of tons daily with minimal human intervention.

Mechanization has not only enabled mass availability of tomato paste worldwide but has also enhanced food safety, traceability, and sustainability. It stands as a testament to how technology can elevate a simple agricultural product into a globally vital ingredient.

Mechanization of ice cream manufacturing

Ice cream had its origins in Europe and was introduced later to the United States where it developed into an industry. It is widely believed that ice cream evolved from iced beverages and water ices.

In 1674 Nicholas Lemery published a recipe for water ice in his book Recueil de Curiosités les plus rares et admirables and two years later Pierre described freezing a mixture of fruit, cream and sugar by using snow and saltpeter.

Beginning of the 18th century, Italian brand leaders the Neapolitans had learned to combine vanilla, strawberry and chocolate ices in the famous trinity.

Ice cream probably came to the United States with the early English settlers. In 1851, the first wholesale ice cream industry in the United States was established in Baltimore, Maryland.

Ice cream was made by hand until in the 1840s Nancy Johnson of Philadelphia invented the first ice cream making machine. She was only the 24th woman to be granted a US patent when she received one in 1843 for her invention of a hand-cranked ice cream freezer, a labor-saving device that led to expanded consumption of ice cream.

The invention simplified ice cream production and ensured a more uniform texture that had previously been possible.

In 1851 Jacob Fussell of Baltimore the owner of a dairy shop, at the end of the day pours leftover cream and milk into the artificial freezer, which he made into ice cream and shortly afterwards opens the first ice cream factory, in Seven Valleys. He was the first to manufacture ice cream on a large scale.

The development of condensed and dried milks and the introduction of the pasteurizer and homogenizer, improved freezers, and other preserving equipment accompanied the growth of this industry after 1900.

Until World War II, virtually all ice cream manufacturers created their product by a method known as ‘batch freezing’.

After the war, commercial refrigeration and more sophisticated ice cream makers came along, and batch freezers disappeared. The first ice cream filling and packaging machines were introduced by Mojonnier Brothers and Sealright firms around 1920, and in 1923 the Nizer Cabinet Company introduced the first automatic electric freezer.

In 1926, Clarence Vogt from Louisville invents the first continuous process freezer.

In the latter half of the 20th century, automated equipment accelerated the process of manufacturing ice cream, guaranteed a more uniform product and improved sanitation in the plant.

In 1927, Otello Cattabriga an ingenious Italian manufacturer from Bologna patented a mechanical system to make Italian style gelato. His system of attaching a motor to the blending system became highly successful and he soon left his shop in Via Mazzini to manufacture his “electric motor-ice-cream-makers” on an industrial scale.

With the continuous commercial freezers, the mix of cream, sugar and eggs was poured in and quickly whipped with fast moving beaters. These machines continuously spit out the ice cream.

Mechanization of pasta production

Although pasta products were first introduced in Italy in the 13th century, efficient manufacturing equipment and high-quality ingredients have been available only since the 20th century. Prior to the industrial revolution, most pasta products were-made by hand in small shops.

In 1800, a first mechanical device for making pasta appeared in Italy. The first American pasta factory was opened in Brooklyn, New York, in 1848, by a Frenchman named Antoine Zerega, who spread his spaghetti strands on the roof to dry in the sunshine.

Around 1850, the first hand-operated pasta press was built. By 1860 more elaborated presses had been had been made. By increasing the popularity of pasta it required more efficient production process to be developed.

By early 1900s, mixers, kneaders, hydraulic piston type extrusion presses and drying cabinets were available for batch manufacturing of pasta.

First extrusion process was invented in 1707 by Joseph Bramah. The first precursors to the modern extruder were developed in the early 19th century. Since 1930s, extrusion method had been used for production of dry pasta.

History of Modern Pasta Processing

Mechanization of pasta manufacturing began during the industrial revolution. The first mechanical devices for pasta processing were developed in the early 1700s.

Pasta making in Italy had become something of a Neapolitan specialty by the nineteenth century and it was in Naples that production began to be fully commercialized and industrialized.

Extrusion processes were used by then, hydraulic presses were designed in the mid-1800s, and late in the nineteenth century kneaders came into use.

It was also probably in the 1800s that the marriage of pasta with tomatoes in cooking occurred. Southern Italy is an ideal for growing of tomatoes. During this century pasta processing was a batch manufacturing process which by its nature was laborious and restricted productivity.

It was not until the early twentieth century that drying cabinets became available. Pasta processing remained a batch manufacturing process until the 1930s, when continuous extrusion using an extrusion auger revolutionized the process. The Buhler Brothers from Switzerland were the first to incorporate an extrusion worm into a continuous press.

Automatic dryers were the added to the continuous with Augusto Fava created with manufacturing and installing the first continuous pasta dryer. The first continuous automatic production line that processed semolina into pasta ready for packaging was designed in 1946.
