Drying Lettuce with Vibration

Drying Lettuce with Vibration

A Netter customer in the food industry was putting lettuce through a cleaning process that used a conveyor sieve for drying and transporting the product. During the wash, water is sprayed on the lettuce, rinsing dirt and sand from the lettuce leaves. From there, the lettuce is dried and transported along a conveyor system, resulting in a runoff of water that contains dirt and sand. The goal of the customer was to dry the lettuce, move it to the next step in the process, and filter as much of the sand and dirt as possible from the water.

The customer purchased a Netter NEG 2570 electric external vibrator and installed it on a stainless steel conveyor sieve. The vibration shook the water from the lettuce and moved it gently along the conveyor, drying it thoroughly without damaging the product. Also, because the equipment is constructed from stainless steel, it is relatively easy to clean between batches.
