Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing almond shelling machines struggle to efficiently separate soft-shelled and hard-shelled almonds, as they require different treatment processes, leading to inefficiencies and a high percentage of non-shelled almonds.
Innovation Solution
A shelling machine with a vibrating/feed metering device at the inlet and a lowerable retaining element at the outlet, allowing continuous feed and controlled separation of soft-shelled and hard-shelled almonds, with a variable speed motor to adapt to different nut types, and aspiration to manage dust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single shelling machine is used for both soft-shelled and hard-shelled almonds, then the machine structure remains simple, but the shelling effectiveness deteriorates because hard-shelled almonds cannot be properly shelled with the same mechanism designed for soft-shelled almonds
Solution Approach 1:
The system is divided into two separate processing lines: one for soft-shelled almonds and another for hard-shelled almonds. Each line has its own shelling machine optimized for the specific shell hardness, ensuring high shelling effectiveness for each type without requiring a complex universal machine
Solution Approach 2:
The system achieves multi-functionality by processing both soft-shelled and hard-shelled almonds through separate dedicated machines, allowing the overall system to handle multiple nut types effectively while each individual machine remains structurally simple and optimized for its specific function
2Productivity
If the machine processes mixed almonds continuously, then productivity increases, but the quality of kernel extraction deteriorates because hard-shelled almonds require different treatment parameters
Solution Approach 1:
The incoming mixed almond stream is segmented into soft-shelled and hard-shelled categories through detection systems, and each segment is routed to the appropriate shelling machine with optimized parameters, ensuring high kernel extraction quality for each type while maintaining continuous overall productivity
Solution Approach 2:
Different processing parameters (such as shelling force, speed, and mechanism settings) are applied to each almond type based on detection results, allowing optimal kernel extraction quality for both soft-shelled and hard-shelled almonds while processing them in a continuous workflow
3Device complexity
If the motor is positioned close to the outlet for compact design, then device complexity is reduced, but the motor reliability deteriorates due to dust accumulation from kernel ejection
Solution Approach 1:
The motor is extracted from the dust-prone area near the kernel outlet and positioned in a cleaner location, separating the power source from the harmful dust environment while maintaining compact overall machine design through optimized component layout
Solution Approach 2:
A protective arrangement or dust extraction system acts as an intermediary between the motor and the dust-generating kernel ejection area, protecting the motor from dust accumulation while allowing the motor to remain positioned for efficient power transmission
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The machine achieves improved kernel extraction and separation efficiency, reducing non-shelled almonds and increasing production, while maintaining kernel quality and reducing maintenance needs.
Implementation Method 1
a rotary shaft, supported on end bearings, provided with radially projecting fingers to act on the almonds and drive the relative movement thereof
Implementation Method 2
a hopper equipped with a vibrating/feed metering device, which prevents the machine from being without material
Implementation Method 3
the action for opening the retaining element can be carried out manually or automatically. In the embodiment of the present invention, it has been provided the retained product exits due to overflowing

AI summary
A shelling-separating machine for almonds and other soft-shelled nuts is provided incorporating operational and functional features which ensure the obtaining of the kernel in optimal conditions, while at the same time allowing for an effective separation of the almonds and other hard-shelled nuts that may accompany the soft-shelled nuts. At the inlet end, the machine provides a device for continuously feeding the product for the purpose of eliminating obstructions inside such machine. At the outlet end, the machine provides a retaining device which can be manually or automatically actuated and which keeps the outlet closed in order to retain the non-shelled product until the operational conditions recommend the actuation and opening of such retaining device to allow the non-shelled product to exit the machine, preferably by the overflow with respect to a previously established level.
