MEP.500 | Preparation, Selection and Pre-Washing Table

Product Characteristics

Featuring an excellent water transport and prewashing system, which helps removing excess of soil and dirt from the selected leaves, MEP.500 by NHS Máquinas is designed to enable up to six operators to perform the first stage related to the feet of leaf-plants coming from the field.

How does MEP 500 work?

MEP.500 consists of a workbench with six workstations, containing polyethylene “cutting boards”, on which the bating is done. At the center of the workstations, there is a U-shaped bowl, like a river, which transports the selected leaves to the washing tank. The prism-shaped tank facilitates decanting of dirt and it is provided with a water injection system that performs an efficient prewashing process. The equipment tank is also provided with a barrier for the circulating water to be collected after the sieving system. Finally, to transport the products to the next stage, MEP.500 is equipped with a blue polypropylene pass-through conveyor. Optionally, MEP.500 is provided with a system of deflectors that enables raising the water level of the washing river, thus, the control of the exposure time during transport is longer, which helps removing insects from the leaf-plants
