Effective, gentle and economical washing of up to 2,500 kg per hour

The HEWA 3800 is a further development of the GEWA 3800 PLUS. It is optimized with regard to hygiene and a reduced cleaning time, for example thanks to a design with no horizontal surfaces, which allows the water to optimally discharge. What's more, the entire machine can be dismantled for simple and thorough cleaning.

Like the GEWA 3800 PLUS the machine 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 by 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 HEWA 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.

Avantages

HEWA 3800 de KRONEN : Il est optimisé en termes d'hygiène et de réduction du temps de nettoyage.

Maximum hygiene, rapid cleaning and maintenance

The HEWA 3800 is optimized in terms of hygiene and easy cleaning. The machine can be completely dismantled for rapid and thorough cleaning. The design concept also ensures maximum hygiene, for example the fact that the machine has no horizontal surfaces whatsoever, thus allowing the water to optimally discharge. What’s more, all edges are designed to avoid the formation of biofilm. The vibration motors, all pipes, the pump casing, the wash and pump tanks and the covers and switch cabinet are made from AISI 304 stainless steel.

Tous les laveurs HEWA de KRONEN sont disponibles avec évacuation vibrante ou sur tapis - le choix de l'évacuation dépend du produit et des exigences de l'utilisateur.

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 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. HEWA 3800)

Le système de lavage GEWA de KRONEN garantit un lavage efficace et en douceur et réduit la consommation d'eau et l'encombrement

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 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. HEWA 3800)

Le laveur HEWA 3800 de KRONEN est ultra flexible et s’adapte aux exigences individuelles grâce à une construction modulaire et compacte

Compact and modular design

Thanks to the HELICAL washing system, the HEWA washing machine is particularly compact. It also has a modular design, which enables the flexible adaptation of the machine to meet 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.

Évacuation des insectes et des particules du laveur HEWA de KRONEN - accès idéal et donc facile à nettoyer

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.

L’évacuation latérale des particules du laveur HEWA KRONEN protège les pompes et permet de travailler en continu, même avec des produits qui moussent et qui contiennent de nombreuses particules.

Lateral fine particle removal drum

The lateral fine particle removal drum with a slotted strainer opening of 0.5 mm filters particles out of the circulating wash water. It enables continuous operation without blocking the filter above the pump tank and protects the pumps. This is particularly important for products that foam and contain many small particles. (Fig. HEWA 3800)

Dans le cadre d’une conception hygiénique optimale, le HEWA de KRONEN peut être équipé en option d’une prise de pression.

Pressure switch for water level measurement

Within the scope of optimal hygienic design, the HEWA can now be optionally fitted with a pressure switch. The device is mounted outside the filter tank so that the tank can be cleaned easily. With the help of the pressure switch, the level of the wash water in the filter tank can be precisely determined, and additional water levels can be set. This simplifies the retrofitting of a water management system (WMS). The pressure switch is already provided as standard when you purchase a WMS. (Fig. HEWA 3800)

Le système d'air des laveurs GEWA de KRONEN génère des bulles d'air dans la cuve de lavage, pour un résultat optimal avec les produits à feuilles et frisés

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.

Sand trap funnel for products with a high sand content

A sand trap funnel for GEWA PLUS or HEWA washing machines is recommended when washing heavily soiled products (e.g. lamb's lettuce). It can accommodate 49 liters of the sand-water mixture and can be emptied manually by means of a ball valve or regulated by an automatic flow control. In the second case, the parameters (e.g. opening cycle and duration) can be set so that automatic regular emptying takes place, in combination with the water management system. (Fig. GEWA 4000)

La fonction de temps d’exposition des laveurs GEWA de KRONEN optimise l'hygiène et la conservation grâce au temps de contact réglable librement.

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)

Le système de gestion de l'eau des laveurs GEWA PLUS de KRONEN permet un remplissage et une vidange centralisés de la cuve de lavage

Water management system (WMS)

The WMS for the GEWA PLUS or HEWA washing machines enables centrally controlled filling and emptying of the washing machines. During operation, an additional level sensor automatically regulates the water level in the washing machine. If the water level drops too low, the pneumatic infeed valves are automatically opened and fresh water is provided. The standard system is comprised of two valves for filling and two for emptying the machine, as well as the necessary pipe system. Other versions are also available on request. The WMS is operated via the switch cabinet. (Fig. GEWA 4000)

Le système de recyclage de l'eau des laveurs GEWA PLUS de KRONEN dans une chaîne de transformation réutilise plusieurs fois l'eau de lavage, ce qui réduit la consommation d'eau

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.

Cleaning trolley for the lateral fine particle removal drum

The trolley makes it easier to clean GEWA and HEWA washing machines. The lateral fine particle removal drum can be taken out of the machine and placed on the mobile trolley, on which it is easy to transport and clean.
