Technology developed to keep all the features of the fruit intact

• As the grapes are fed into the Lugana’s feed hopper, a short auger meters them into the rotating destemmer drum. By destemming prior to crushing a superior must is obtained. The destemming drum and beaters operate at a low RPM to prevent maceration of the fruit and to keep the grape stems intact. To make this operation more delicate, the destemming paddles are now made of food grade polyurethane plastic instead of metal. The rotary destemming paddles offer the winemaker the possibility of adjusting the destemmer axle for the best operation on specific grape varieties. The speed of the grape in-feed auger is adjustable independent of the speed of the destemming paddles. This insures that the flow of grapes through the machine can be optimized for each variety.
A second variable speed drive allows the winemaker to optimize the rotation speed of the destemming drum and the beaters.
The speed control operates on both the drum and the beaters keeping their individual operation in proper synchronization.
• The Lugana’s crushing rollers are mounted under the destemming drum so no stems are crushed into the must. The rollers are made of rubber and they are with small teeth in order to have the right crushing action.
Two calibrated hand wheels on the outside of the machine allow the operator to set the roller spacing to give the desired amount of crushing.

Sanitation and maintenance

• The “LUGANA 3 R” is designed to be fully disassembled for cleaning in few seconds. So you can easily clean all the parts of the machine that still have pieces of worked grapes.
Its transmission and its motor are completely isolated from the part where the product is worked.

Safety

The electrical safety system stops the machine if any of the covers are opened. The machine can only be restarted when the covers are latched back into place and the start button pressed again. The “LUGANA 3 R” is also equipped with an emergency stop switch for the operator.

Optionals

• Cage made of plastic.
• Must collection tank.
