Fruit Tec REDpulse pneumatic defoliation for apples demonstrated

Demonstrations of the Fruit Tec REDpulse pneumatic defoliation for apples are scheduled this week in Washington state.

REDpulse defoliation removes most of the shading leaves completely or parts of it.

Light parts of the fruit skin are clearly visible. These parts have been proteced by leaves before, not allowing an even exposure and coloration.

The REDpulse defoliation module enables red colored apple varieties to receive a more intense and even exposure to light. REDpulse is a new, innovative, incapsulated and purely pneumatic defoliation module for removing shading leaves.

High frequency pulsating air-stream removes leaves and parts of leaves within the working zone. Less shading enables light and temperature exposure. The result is an even and intense coloration of the fruits.

The part of Class 1 / class A fruits is increased and also the number of pickings can be reduced. During harvest a better and early visibility of the fruits eases harvesting process.

The workflow is improved and distances within the orchard during harvesting can be reduced. Optimal results have been achieved in modern, narrow, mechanically pruned orchards. In operation, REDpulse fruits do not get in contact with rotating parts of the machine, that could harm the sensitive skin of the fruits or even cause physical damages. Fruits which are positioned away from the tree are carefully led past by a specially designed protector metal plate. Operating is comfortable with Joystick & Display. REDpulse is working energy efficient.

Karen Lewis, Washington State University Tree Fruit Extension Team Leader, said there are three opportunities to view the demo:
