An intelligent solution for a precise, hygienic, and efficient washing process in the food industry

Naddeo Technologies is a company that designs and manufactures innovative solutions for food companies. Our machines are precise and customized, meaning they are tailored to the specific needs of each food company. Naddeo uses advanced technologies and software to create solutions that enhance the efficiency of various processes, including production, quality control, supply chain management, and more.

We would like to focus on the crucial stage of product washing and how Naddeo Technologies has worked to design tools perfectly capable of achieving the goal quickly and effectively.

At the heart of the food industry, the ongoing search for innovations aims to improve the quality, efficiency, and safety of products that reach our tables. A significant step in this direction is represented by the Naddeo WM Bubble Washer, an intelligent engineering feat that is changing the way leafy vegetables and salads are treated and prepared.

The Naddeo WM Bubble Washer has been precisely designed to meet the intensive washing needs of cut leafy vegetables, whole vegetables, and salads that can float or sink. Its main function is to ensure an accurate and hygienic washing process, revolutionizing the very concept of cleanliness in the food industry.

The construction of the washer is entirely made of AISI 316 stainless steel and plastic, creating a hygienic and easy-to-clean environment. This careful choice of materials not only ensures maximum hygiene but also reflects a commitment to the durability and resistance of the machinery over time.

Automation is the key to the Naddeo WM Bubble Washer. A sophisticated touch control panel allows the adjustment of washer parameters, activating and deactivating various components for total control. The combination of a circulation pump and an air injection unit creates a peristaltic movement, ensuring a uniform and controlled washing of vegetables through water.

The Naddeo WM Bubble Washer is not just a standard product but also offers a range of customizable options to meet specific production needs. Covers to prevent chlorine diffusion, integrated cooling units, suction systems, and various water spraying configurations are just some of the available options.

In addition to technological innovation, the Naddeo WM Bubble Washer also stands out for its attention to consumption efficiency. Water consumption varies based on tank size, ensuring responsible use of water resources without compromising performance.

Each washer is equipped with advanced features to ensure an efficient and hygienic washing process. Motorized fins facilitate the movement of salad through the system, while the water filter with rotating sieve removes unwanted particles. The dehydration belt ensures effective removal of excess water from the product. Insect traps help maintain a clean and hygienic working environment. The automatic filling and draining function greatly simplifies the operational process. Automatic control of air injection, along with stainless steel fans, offers a practical solution for temperature management. Inverters on all motors and pumps, with stainless steel covers, ensure superior durability and resistance. Dedicated cable rings for hygiene and cleaning, along with retractable ends of the belts, facilitate maintenance operations. Finally, auto-drainage tanks with automatic valves and level probes in recirculation tanks contribute to efficient water level management and pump protection.

In conclusion, the Naddeo WM Bubble Washer is much more than a simple industrial machinery. It represents a step forward in the food industry, where technology meets practicality, offering clean, safe, and high-quality products on our tables. The washer, entirely constructed from AISI 316 stainless steel, offers several significant advantages. The robustness and durability of the material ensure not only a long lifespan but also make the washer easy to clean and maintain in optimal conditions. The integrated filtering system effectively removes heavy particles, such as small stones, ensuring no dirt passes through the valve. The motorized fins in the device are designed to gently move the product through the washing process, avoiding damage. Isolators on the motors allow safe access during the operation of the entire line. Moreover, the presence of three water discharge ports simplifies the water flow at the end of production. The design also includes an easy-to-use lever to lower the belt head, simplifying the removal of trapped salad leaves between the belt components. In summary, the washer not only offers efficient performance but also stands out for its practicality and ease of use, contributing to optimizing the industrial washing process.
