HEWA 3800 HELICAL washing machine

Optimized with regard to hygiene and cleaning: Effective, gentle and economical washing of up to 2,500 kg per hour

The HEWA 3800 HELICAL washing machine, which was launched in 2022, is a further development of the GEWA 3800 PLUS. It is used for the continuous pre-washing, washing, disinfection, mixing, treatment and rinsing of lettuce, fruit and vegetables.

The machine can process up to 2,500 kg per hour and has been optimized in terms of hygiene and a reduced cleaning time. It can be completely dismantled for rapid and thorough cleaning. The machine has no horizontal surfaces, thus allowing the water to optimally discharge. All edges are designed to avoid the formation of biofilm.

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. 

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.
