Baby leaf lettuce is a flavorsome and particularly delicate alternative to conventional salad leaves. It comes in many different varieties and is therefore ideal for freshening up a salad mix with leaves in various shapes and sizes. Unlike heads of lettuce, preparing baby leaf lettuce for processing involves less work because the leaves do not have to be separated first. That said, the sensitive leaves of baby leaf lettuce have a low bulk density and therefore place high demands on the processing procedure.

To achieve an end product with appealing aesthetics and the longest possible shelf life, it is essential that the mechanical stress placed on the leaves is as low as possible during processing steps such as washing and drying. To avoid damage to the leaves, the low bulk density and consequently high spatial requirements of the product need to be considered. KRONEN offers a variety of machines that are not only tailored to meet the special demands of sensitive products such as baby leaf lettuce but also designed to save as much space and converse as many resources as possible.

Baby leaf lettuce is often used as an ingredient in salad mixes, in which different varieties of baby leaf lettuce are combined and packaged as a ready-to-eat product. When it comes to achieving a constant mix ratio when producing salad mixes, a weighing system can be used to add consistent quantities of the various products to the washing machines while ensuring a constant product flow.

The GEWA AF pre-washing machine and the GEWA XL helical washing machine, which can be perfectly connected in a processing line, gently and efficiently wash large quantities of baby leaf lettuce. The specially developed submergence system puts the product in an optimal underwater position for an effective start to the washing process. Both washing machines complement each other perfectly and combine the flotation washing technique with the helical washing system to achieve optimal washing results and a high capacity. Given that KRONEN is constantly advancing its washing systems, both machines take up less space and require low water quantities.

The K650 or K850 drying systems can be used for the drying process depending on the capacity required. The optimally coordinated and automated procedure enables the lettuce leaves to be gently spin-dried. What’s more, the washing machines and drying systems can be optimally combined to form processing lines, thus ensuring a continuous processing procedure that produces consistently high-quality results.

Due to their sweetness and aroma mangoes are an ideal ingredient in many foods and dishes whether in fruit salad, dried fruit, juice or in smoothies, ice cream, chutneys or as an ingredient in various dishes. This delicate fruit is in high demand and not only in the countries where the mango trees grow. Many mango producing countries export mangoes all over the world either as whole fresh fruit or as a ready produced product such as frozen cubes or dried slices.

Peeling and slicing mangoes, their high sugar content and the easy bruising especially of very ripe fruit pose a challenge when processing. KRONEN offers suitable solutions for different types of mango processing used by customers worldwide. Such solutions range from specialised machines and all-purpose machines to complete processing lines – of which only a few are mentioned here.

Using a wash cycle with hygienising additives in the Deconwa Prep the surface area of mangoes can be decontaminated before moving on to the next processing steps. In this way optimal hygiene is ensured at the start of the processing procedure and therefore the washing solution can be used for the transition from low care to high care production areas.

The Mango Peeling and Stoning Machine 20 developed by KRONEN partner ZTI Smart Machines means peeling and de-stoning is automated. During the peeling process the delicate fruit is held in place via the stone to prevent damage and simultaneously produces a visually appealing product.

The versatile GS 10-2 belt cutter can be used to further process the peeled, de-stoned mangoes. It cuts the fruit into slices or cubes. Using the specially designed cube grid to make either 15 x 15mm, 20 x 20mm or 25 x 25 mm cubes, wastage due to the fine pieces can be reduced.

In order to improve their shelf-life the processed mangoes can be treated in the KDB 120 dipping bath bath using various additives. The KDB 120 now operates with greatly reduced water quantities thereby saving resources and costs. Also, the product is de-watered upon discharge so as to prevent ice forming on the surface during further processing as e.g. a frozen product.

The above-mentioned solutions are complemented by a variety of additional KRONEN machines and can be integrated in processing lines. The Deconwa Prep, the GS 10-2 belt cutter or the KDB 120 immersion bath can also be used flexibly in processing a large variety of other fruits and vegetables.

Peppers are colourful, healthy and versatile. Their use ranges from fresh ingredients in fresh-cut products to convenience foods or sausage fillings and in a wide variety of frozen products. Many diverse demands are made on processing due to the extensive uses and the varying quality of peppers as raw material depending on the season and cultivation method (greenhouse or outdoors). As a solution KRONEN offers a comprehensive portfolio of machines which provides efficient processing with minimum labour, least possible amount of waste and top-quality processing.

The PDS4L pepper decoring and cutting system uses a semi-automated process which optimally positions the peppers in the product holders and then cores, halves and quarters them. Waste and usable product are separated. The yield is approximately 85% depending on the variety and quality of the pepper. Capacity is up to 750 kg per hour. You can experience this innovation live at the Fruit Logistica in Berlin!

Additional solutions specially developed for processing peppers are the GEWA 3850V PLUS and GEWA 5050V PLUS pepper washing machines. Their automated special separation feature means they are optimally suited for washing and sorting cut peppers. The peppers can be processed entirely without having to previously remove the core and stalk. A sophisticated system using various water flows ensures waste is separated from usable product thereby eliminating costly sorting procedures. The GEWAs achieve a yield of approximately 70% with a capacity of up to 800 or rather 3,500 kg of usable product per hour.

The GS 10-2 belt cutting machine and the GS 20 for larger capacities are designed to cut pepper halves into small (e.g. 35 x 35mm) squares and also into strips quickly, gently and with optimum cutting results, both for raw and grilled peppers.

With its DEW 200 dewatering press KRONEN also provides a further processing solution for cut pre-processed peppers which have been frozen and then defrosted for use e.g. as a filling in sausage or delicatessen products. The DEW 200 removes excess liquid from the defrosted peppers thereby avoiding long draining times.

In addition, several other KRONEN machines can be used for the processing of peppers depending on the production requirements - such as the KUJ V cutting machine for the production of cubes in different sizes or the PGW pneumatical grid cutting machine for the production of different shapes or figures.

For several years now, the popularity of avocados has been growing worldwide - as have demand and production volumes.

In addition to the famous guacamole, the specialty that originated in Mexico, avocados are now often used as a sandwich topping or ingredient in salads. And because you eat with your eyes first, the production of visually appealing product pieces is required for everything that is not processed as a dip. Despite optimal ripeness, this new requirement presented a challenge that could only be solved with manual processing. However, the constant strain caused by the necessary rotating hand movements when peeling the avocados often leads to health complaints among production workers.

Therefore, the only efficient way to meet the increasing demand is with machine-assisted or automatic processing:

With the Convenience Avocado line, KRONEN offers a semi-automated solution for peeling and pitting large quantities. The gentle processing produces halves from the delicate fruit that look as if they were peeled by hand. The products are thus optimally prepared for further processing, e.g. cutting into slices or cubes with the GS 10-2 belt cutting machine.

As part of a research project, KRONEN has also developed a new robotics-based solution for fully automated processing of avocados. The processing line is currently tested extensively. The line can be equipped with one, two or three robots and processes up to 1000 avocados per hour with 3 robots. The line enables optimal hygiene and reliable, continuous production. The quality of the visually appealing halved, peeled and, if desired, sliced avocados even surpasses that of manual processing.

Iceberg lettuce is among the top three lettuce products most frequently processed by KRONEN machines at our customers' sites worldwide. Its popularity remains high among private households, gastronomy and convenience manufacturing, even though competition from a variety of other lettuce types is growing.

As a crunchy component of mixed salads, iceberg lettuce continues to play an important role. The great advantage in processing iceberg lettuce is that it can also be cut particularly well into smaller pieces, e.g. squares or strips.

In particular, the KRONEN lines for processing salad with large capacities of 2 tons and more per hour are successfully used internationally for preparing, cutting, washing, drying, mixing and packing iceberg lettuce. These include, for example, the Mulitcorer and DCM series from our partner HiTec Foodsystems, machines for decoring iceberg lettuce in a continuous process. The prepared lettuce can then be cut into the desired shape with the GS 20 belt cutting machine and then passes through a washing machine, as for example the GEWA XL. For efficient spin-drying of large quantities of lettuce, the continuous KRONEN drying systems are used and then the ready-to-eat lettuce can be packed.

The KRONEN processing lines ensure efficient processing by optimally coordinated machines and are of course also suitable for processing more sensitive types of lettuce due to various setting options. Thus, with a wide range of individual machines and complete processing lines, KRONEN offers solutions for the most diverse requirements in the production of ready-to-eat (iceberg) lettuce.
