Tomatoes are a staple in our diets, used in a myriad of culinary dishes worldwide. In order to improve the neatness of tomatoes when they are sold, tomatoes are graded before being shipped to supermarkets. But what are the types of tomato sorting machine. Two common methods for sorting tomatoes are weight sorting and size sorting. In this article, we will delve into these methods, exploring their functions, benefits, and applications.

Weight sorting machines

Weight sorting machines are designed to separate tomatoes based on their weight. These machines utilize advanced technology to accurately measure the weight of each tomato and categorize them into different classes. The key components of weight sorting machines include conveyors, sensors, and sorting mechanisms.

How it works:

  • Conveyors transport tomatoes to the weighing station.
  • Sensors, such as load cells, measure the weight of each tomato as it passes through.
  • Based on predefined weight thresholds, the sorting mechanism directs the tomatoes into appropriate bins or channels.

Benefits of weight sorting:

  • Precise sorting: Weight sorting machines provide a high level of accuracy, ensuring that tomatoes are classified based on their exact weight.
  • Reduced waste: By sorting tomatoes by weight, this method reduces the chances of overripe or underripe fruits making it into the final packaging.
  • Increased efficiency: Automation of this process significantly increases the sorting speed, making it ideal for large-scale operations.
  • It is also useful for ensuring uniform weight in packaged fresh tomatoes sold in supermarkets.

Size sorting machines

Size sorting machines, on the other hand, categorize tomatoes based on their dimensions, primarily their diameter.

How it works:

  • Conveyors transport tomatoes to the scanning station.
  • Cameras or sensors capture images of each tomato and analyze its size.
  • Based on predefined size criteria, the sorting mechanism redirects the tomatoes to their respective destinations.

Benefits of size sorting:

  • Uniform appearance: Size sorting ensures that tomatoes in the same packaging have a similar appearance, which is crucial for aesthetic reasons and consumer satisfaction.
  • Versatility: It is adaptable to various fruits and vegetables, making it suitable for farms that grow a variety of produce.
  • Improved quality control: Size sorting helps maintain a consistent product quality, meeting consumer expectations.


Size sorting is commonly used in the fresh produce market, especially for tomatoes sold as whole fruits in supermarkets and markets.

Tomato sorting machines play a crucial role in the agricultural and food processing sectors, helping to streamline the sorting and packaging of these popular fruits. Weight sorting machines provide precision and reduce waste, while size sorting machines ensure uniformity and aesthetic appeal. Regardless of the method chosen, these sorting machines contribute to the efficiency and quality of tomato production, benefitting both producers and consumers.
