Cost-reduced ECO model: wash up to 4,000 kilograms per hour gently and thoroughly

The GEWA 5000 ECO is used for pre-washing, washing, disinfecting, mixing, treating and rinsing lettuce, vegetables and fruit. It can be used flexibly and is usually positioned downstream of a cutting machine between the low-care and high-care area.

The wash tank is filled either automatically via an infeed belt or manually. Both floating and sinking products are conveyed through the wash tank by the HELICAL washing system in a spiral movement. The flow rate and movement of the water in the wash tank can be adjusted to suit different products. At the end of the wash tank, the product and the water are transported to a vibration or belt outfeed by means of an overflow and sprayed with a fresh water shower. The water flows through a strainer into the pump tank, from which it is pumped back into the wash tank and used again.

Versatile application options:

Lettuce (e.g. baby leaf, iceberg): cut and whole leaves
Vegetables: cut and whole
Herbs (e.g. parsley, chives): loose and in bunches
Fruit (e.g. pineapple, melon): cut and whole
Other leafy products (e.g. spinach), tuber products, pulses and mushrooms, as well as seaweed or kelp

As a result, the GEWA ensures an undamaged, optimally cleaned product that, if necessary, has been disinfected with a washing additive. In addition, the product can be efficiently mixed (e.g. mixed salads) and cooled down by the washing process. Small particles are also sorted out in the washing machine with a vibration outfeed.

Fresh water spray of the GEWA washing machines from KRONEN rinses and cleans the product during discharge out of the machine — A fresh water spray above the discharge belt sprays any residues of the disinfecting agent off the washed product or represents an additional rinsing step with fresh water – at the same time, the washing tank is thus constantly refilled. (Fig. GEWA XL)

Benefits

All GEWA washing machines from KRONEN are available with vibration or belt discharge – which discharge is chosen depends on the product and user’s requirements

Vibration or belt outfeed

The washing machines are available with vibration or belt outfeed. The chosen outfeed depends on the specific requirements. The vibration outfeed ensures preliminary dewatering of the product, sorts out small particles and is easier to clean. Filter strainers with hole sizes of 2, 5, 8 or 10 mm, for example, are available, enabling product-specific adaptations. In addition to the standard version, a version with an outfeed extended by 500 mm (GEWA PLUS) or 400 mm (GEWA ECO) is available. A belt outfeed may enable a higher capacity and is more suitable for individual products. What’s more, the machine does not necessarily need to be raised in case of a wash cascade function. (Fig. GEWA 3800V PLUS)

The GEWA HELICAL washing system from KRONEN guarantees effective, gentle washing and reduces water consumption and space requirement

Highly effective, gentle HELICAL washing system

KRONEN’s HELICAL washing system ensures that the product travels along a spiral-shaped route in the wash tank that is up to ten times longer than the wash tank. Due to the ideal distribution, the product is loosened up and constantly rinsed completely during the cleaning process. Products are therefore washed thoroughly and gently, water consumption is considerably reduced, and the machine is ideal for a wide range of applications.

Sand trap in the GEWA washing machines from KRONEN for loosened dirt and sand supports the perfect washing result

Sand trap sedimentation unit

The sand trap integrated into the wash tank separates the loosened heavy dirt (e.g. small stones) and sand from the product flow. Dirt and sand settle in the sand trap at the bottom of the wash tank and are not discharged from the wash tank with the product. (Fig. GEWA 3800 PLUS)

With its modular, compact design, the GEWA 2600 ECO from KRONEN allows great flexibility and adaptation to individual requirements

Compact and modular design

Thanks to the HELICAL washing system, HEWA washing machines are particularly compact. They also have a modular design, which enables the flexible adaptation of the machine to the requirements in production operations. For example, it is possible to retrofit the air system or other options that can be quickly and easily installed as a kit.

Insect and fine particle discharge of the GEWA washing machine from KRONEN – ideally accessible and thus easy to clean

Insect and fine particle removal system

The insect and fine particle system is available in two versions: firstly as a removable, static basket insert for cut, less sensitive products and secondly as a rotary insect removal unit with a drum for more sensitive products and whole leaves. The insect drum can be easily swiveled out of the wash tank, for example for cleaning. It also has an open design for easy access. At the same time, operational safety is guaranteed. (Fig. GEWA 3800 PLUS)

Air system

The KRONEN air system enables the combination of the benefits of the HELICAL washing system with those of the flotation system. By means of a blower, air is conveyed through a pipe system with a large number of perforations. This pipe system generates air bubbles in the wash tank. Especially in the case of sensitive products such as whole lettuce leaves or difficult products such as curly-leaf parsley or lollo rosso lettuce leaves, the combination of reduced water rotation and the air bubbles provides an optimal result.

Dwell time function of the GEWA washing machines from KRONEN optimizes hygiene and shelf life thanks to the freely adjustable contact time

Retention time function

The retention time is realized by a retaining flap, which automatically controls how long the products remain in the wash tank. This enables the freely adjustable contact time of the products with the water to be guaranteed when using washing additives. This step forms a fundamental basis for hygiene in further processing. (Fig. GEWA 4000)

Water recycling system

The KRONEN Water Recycling System (WRS) is used in washing lines comprised of at least two GEWA or HEWA washing machines. Excess water from the second washing machine is returned to the first washing machine, considerably reducing the overall water consumption. The system makes use of the fact that the first washing machine generally carries the higher dirt and germ load. The water from the second washing machine, which is cleaner, is therefore used to refresh the water cycle.
