After the harvest, fruits and vegetables of all types have to be sorted, packaged and transported: apples, avocados, cherries, citrus, kiwifruit, onions, pears, peppers, potatoes, salad, strawberries, stone fruit, tomatoes, etc. The list is almost unlimited. A wide range of technologies have been developed or refined over the years for sorting according to colour, density, diameter, shape and weight.
Supermarkets and consumers are placing ever-higher demands on fruit and vegetables. They want a higher level of consistent quality and are becoming more and more unwilling to accept blemishes.
Grading of fruits and vegetables after harvesting is an essential step in post-harvest management. Grading of fruits and vegetables on the basis of physical characteristics like weight, size, colour, shape, specific gravity, and freedom from diseases depending upon agro climatic conditions. The known methods of grading of fruits and vegetables are manual grading, size grading.
Various companies offer unique solutions to the fruit sorting industry. Here is what some industry players have to say about their product offering:
- Duijndam Machines- used apple & fruit sorting machines
Duijndam Machines is specialized in supplying various used machines for fruit and vegetables growers.
Machines for sorting, washing and packaging are an import part of our 700 machines counting stock. Besides washing, grading and packaging machines we also have machines in stock for seeding, transplanting and harvesting various type of vegetables, fruit and ornamental flowers and plants.
The company has a wide range of sorting machines with a capacity of 500 kg hour till 7500 kg / hour. So these machines can be interesting for small and larger fruit and vegetable farmers.
The purchase team at Duijndam Machines searches for the best used agricultural and horticultural machines in Western Europe on a daily base.
Machines are only bought after they have been thoroughly assessed and tested. The machines are checked technically, cleaned and repaired as soon as they arrive at our location in the Netherlands. Reconditioning is done by our technical staff, in collaboration with specialist experts and manufacturers.
Before delivery we run a final test to make sure the machine is fully operational. If required, we can provide additional services such as transport.
It is important that delicate fruits like apples and pears are not damaged during sorting and processing. It is therefore important to choose a fruit sorting machine that minimises the risk of damage.
The fruit sorting machines from Aweta, Greefa and Wamel perfect have been developed to minimise the risk of damage. Many apple sorting machines have brushes by the singulator and the sorting outfeeds to prevent the apples colliding with each other.
This include the grading and packing machines for tomatoes in South Africa, grading and brushing machines for organic avocados in Kenia and grading machines for mangos in Ivory Coast and Mali.
Sorting is important to the growers since most profit in the fruit industry is made from selling a uniform product. This uniformity can be achieved by sorting the fruit in a fruit sorting machine. Fruit, such as apples, pears, oranges and citrus fruits, can be sorted by weight, size and/or colour. The newer and more extensive machines can even sort by internal and external quality.
The type of sorting is therefore decisive for the choice of a specific fruit sorting machine. A camera, that scans each apple or pear, sorts by colour and often size while the weight of the fruit is determined by a weighbridge which weighs each cup. Sorting by weight or size can be done mechanically or electrically depending on the type of sorting machine and your budget.

- Agrisort- South African Fruit Sorting Technology to the rescue
Fruit sorting machines are expensive capital investments that are supposed to last many years. Sadly, African users who have older legacy machines are often left behind with few options when the electronic parts of their machines need replacement. They are forced to purchase imported machines and pay for them in Euros.
John is an apple farmer in the picturesque Langkloof region of South Africa. At peak times, he processes 60 tons of apples a day, and any downtime on his cup sizer machine is a huge problem. In 2016, all hell broke loose when a nearby lightning strike took out his sizer in the middle of the season. After a few frantic calls and a visit from a sympathetic supplier who could not do much, panic set in. A lucky tip from another farmer ended up in a call to Agrisort. Three days later a team arrived at his farm, worked through the night, and the next day he was packing again at full speed. This is what Agrisort does.
Capetown-based Agrisort is a supplier of 3rd party fruit sorting and sizing control systems. They do not manufacture sorting machines, but instead focus solely on the supply and development of the electronic wizardry that makes these machines work. Their systems are regularly retro-fitted to old machines (of any make) as in the story above, and are also supplied as original equipment for a number of machine manufacturers. If a sizer comes from South Africa, chances are it will have Agrisort electronics and software.
The computer in your cellphone today outperforms the fastest supercomputers of yesteryear.. Things get faster and cheaper with time, and the same should be true
For the technology behind fruit sorting. In the old days, it took expensive computer racks and various “high speed” (read: “very expensive!”) components to get these machines to work, and even then, they were never very accurate.
Agrisort leverages the latest advancements to deliver a world-class product at very attractive prices. The latest in digital weighing and filtering technology does away with frustrating “screwdriver calibration”. Results are accurate to 1gram, even at speeds of up to 5 cups per second – a level of accuracy only matched by a handful of imported machines. Lastly, the intuitive software specially developed for these machines is extremely easy to use. In fact, the average user training session lasts only 5 minutes.
Agrisort is a division of Polygon Technologies, an ISO9001:2015 certified engineering firm established in 2003. It has a local team of development and support engineers, as well as an installation team available for retrofits.
- MAF RODA -A family company with international dimensions
As undisputed market leader in fresh fruit and vegetable grading and packing processes, MAF RODA is committed to bringing high performance solutions, which are adapted to customer exact needs and evolving according to their future development.
The involvement of the Blanc family in the fruit sector dates back to 1905, with the cultivation of orchards. This production experience, which lives on today with the growing of apples in orchards belonging to the family in the Montauban region, brings with it knowledge of the constraints faced by the fruit farmers, and by the same token, strong added value in the daily activity of the company. Passion still drives the development of the company, and is the major asset underpinning its international success.
The MAF RODA Group devotes an average of 3% of its annual turnover to technological innovation. These continuous investment efforts in research have led MAF RODA to possess numerous patents linked to major technological developments enabling it to offer its customers the most cutting-edge tools, to best meet the requirements of their markets.

MAF RODA AGROBOTIC designs and produces bespoke, turnkey solutions to meet your needs. By incorporating in your installations high-performance systems for weight grading, colour and diameter sorting, and inspecting external and internal quality, we can offer you high-performance solutions. Our offering covers the entire fruit and vegetable preparation chain, from supply through packaging to palletizing.
Since 1979, MAF RODA AGROBOTIC has developed its own electronic sensors for sorting fruits and vegetables, and designed cutting-edge technology equipment to meet requirements for measuring weight and external/internal quality: color, volume, diameter, density, shape, and even the sugar content (BRIX index), or checking for internal defects, such as internal browning, for example.
Weight measurement takes place by means of an electronic strain gauge associated with a mechanical weighing conveyor installed on the grader, thereby guaranteeing precise, individual weighing of each item of produce.
The external quality sorting systems developed by MAF RODA AGROBOTIC analyze the surface aspects of fruits and vegetables to detect predefined parameters of color and shape, for example, along with defects on the skin such as puncture marks, mold and bruising. These sensors guarantee optimum selection of the produce for packaging.
Packing is the last phase of the packaging. It must therefore guarantee absolute respect for the fruit or vegetable. Depending on the organisation and the equipment installed on the line, considerable manpower and performance gains can be envisaged at this stage of packaging.
From bulk produce to bedded produce, each fruit and vegetable has its specific packing characteristics. MAF RODA AGROBOTIC is capable of proposing the best-suited solutions for the delicate handling of fruits and vegetables when packing, through to the complete automation of this stage.
