Abstract

A system and methods are provided for removal of undesired portions of a fruit or vegetable, such as removal of calyxes from strawberries before they are flash frozen. An automated process for high-throughput fruit or vegetable calyx removal includes a loading system, an identification system, and a removal system. The loading system is configured to transport the fruit or vegetable through the automated process. The loading system may also orient the fruits or vegetables along an axis of the fruit and or align the fruit or vegetables in a desired pattern, orientation, and/or arrangement. The identification system is configured to locate the calyx and determines calyx position data and an optimal cutting path for individual fruit. The removal system uses data received from the identification system to separate the calyx from the fruit or vegetable.

First claim

What is claimed is:

1. A removal system for removing portions of produce, comprising:
a loading system for introducing the produce into the removal system;
a conveyor system for transporting the produce through the removal system;
an identification system for locating the portions to be removed; and
a cutting system for removing the portions from the produce;
wherein the conveyor system is configured to rotate and orient the produce during transport; and
wherein the conveyor system is configured to cease rotating the produce once the orientations of the portions to be removed are identified.

2. The removal system of claim 1 , wherein the cutting system comprises a plurality of actuated cutting nozzles.

3. The removal system of claim 1 , wherein the conveyor system includes a plurality of roller rods configured to lift the produce from the loading system and transport the produce through the removal system.

4. The removal system of claim 3 , wherein each of the plurality of roller rods comprises a shaped roller for rotating and orienting the produce during transport.

5. The removal system of claim 3 , wherein the identification system includes one or more industrial cameras for taking sequential images of the rotating produce to determine an optimal cutting path.

6. The removal system of claim 5 , wherein the conveyor system is configured to cease rotating the produce once the optimal cutting path is determined.
