Sterilize

Decontamination of whole products with guaranteed dwell time The DECONWA Prep is designed to reduce the load of germs, viruses, and bacteria on the surface of whole fruits and vegetables. Hygienic additives such as chlorine or peracetic acid are added to the wash water. This wet decontamination prepares raw products optimally for further processing and minimizes cross-contamination between products and during peeling or cutting, thus improving shelf life. The DECONWA Prep ensures optimal hygiene at the very beginning of the processing chain and facilitates the smooth transition from "low care" to "high care" production areas. The machine is compact and space-saving, with a low filling height and small footprint. It can be flexibly adjusted to different products and production requirements through various settings and options. The machine's capacity depends on several factors. For example, approximately 1,000 kg of apples can be processed per hour, with a cycle time of 4.5 minutes (1.5 minutes for filling, 30 seconds dwell time, and 2.5 minutes for emptying).

DECONWA Prep optimizes the preparation of fresh fruits and vegetables for further processing through wet decontamination. By using sanitizing additives in the wash water, the microbial load on the surfaces of the products is reduced.

Safe UVC Surface Disinfection for Food, Packaging Materials, and Tools In close collaboration between Kronen GmbH and sterilAir®, the UVC-Lock disinfection chamber was developed for UVC surface disinfection. The UVC-Lock offers a reliable and fast solution to reduce surface microbial load when transitioning into the hygiene area. The dry disinfection process occurs without heat or undesirable residues and additives. Thanks to highly effective UVC technology, we achieve excellent disinfection results in a short time. This allows for a compact design of the machine and its application even for sensitive products. Products are either manually placed or fed via a processing line onto the conveyor belt and passed through a shielded area with UVC emitter tubes. The UVC-Lock enables 360-degree disinfection, with the efficient arrangement of UVC emitters ensuring an almost complete irradiation surface. The stainless steel mesh belt minimizes product shadowing from below. At the end of the conveyor, the disinfected product is transferred, for example, into the high-care area. Versatile Applications: The UVC-Lock is commonly used for surface disinfection of crates, tools, packaging materials (e.g., buckets or cans), food outer packaging (e.g., sausage casings), and fruit and vegetable products before further processing, such as cabbage heads or pre-peeled onions and carrots. The capacity varies depending on the product and contact time, which affects germ reduction. For instance, cabbage heads can be disinfected at a rate of up to 3 t/h with conveyor speeds ranging from 0.05 to 0.3 m/s. For transport crates (600 x 400 mm), up to 900 pieces per hour can be treated at a conveyor speed of 0.2 m/s. Note: The disinfection of food is subject to country-specific legal regulations.

Thanks to UVC surface disinfection, packaging materials, tools, and food are efficiently and safely freed from germs. This process is quick, without heat treatment, and without the use of undesirable additives or residues.

Effective Post-Treatment for Improved Product Shelf Life The KDB 120 immersion bath is specifically designed for the post-treatment of peeled or cut fruits and vegetables. By adding special additives to the water, the shelf life of the treated products is significantly extended. With adjustable fill levels and dwell times, the system allows for resource-efficient and reliable treatment. The product to be treated is introduced into the immersion bath via the feed hopper. Optionally, a lift belt can be integrated for automated filling. As the product moves through the immersion tank, an additional spray from above ensures effective treatment of floating products as well. An optional pre-drying with a blower can be added before the product is transferred either into containers or onto a conveyor belt. The KDB is capable of treating, for example, cut and/or peeled apples within 30 seconds, achieving an impressive capacity of up to 750 kg per hour.

In the KDB 120 immersion treatment system, cut fruits and vegetables are treated using a minimal amount of water, thereby reducing the addition of additives. This helps to increase shelf life and minimize microbial contamination on the surface of the products.

Washing, dipping and disinfecting salad, vegetables and fruit: The DS1000 mobile is a compact bubble bath, ideally designed as an entry-level or additional machine. Equipped as standard with a continuously adjustable blower unit and timer, as well as four wheels with parking brakes and a basket holder for a standard spin basket. Versatile applications: The bubbling effect of the air blower washes cut salad, vegetables, fruit and herbs (whole or cut) hygienically clean and gently. Cut products such as celery, potatoes or apples can be dipped and treated at the same time to prevent discoloration and extend their shelf life. By adding washing additives, whole pieces of vegetables and fruit are dipped and disinfected before processing to avoid possible cross-contamination. The DS1000 mobile is also available in a special version for washing products in boxes (Euronorm 600 x 400 x 200 mm).
