The mealworm sorting machine from Taizy is a fully integrated automated separation system engineered for commercial mealworm farming operations. This automatic insect sorter combines three modular units—a main separator, secondary sorting unit, and optical color sorter—to deliver complete processing in one continuous workflow. Capable of handling 400–600 kg of fresh larvae per hour, or 500–700 kg of pre-dried mealworms with the color sorter attached, this tenebrio separator replaces labor-intensive manual sorting with precision automation.

Unlike basic screening equipment, this mealworm processing machine performs multiple separation tasks simultaneously: frass removal, skin and debris extraction, dust collection, size grading into large/medium/small larvae, and separation of pupae and dead insects from healthy stock. Variable frequency drives control both conveyor belt speed and fan airflow, allowing operators to fine-tune settings for different larval sizes and moisture conditions. The enclosed dust-proof design, quick-change mesh screens, and mobile configuration make this insect grading equipment suitable for small breeding farms and large commercial facilities alike.
What Functions Does a Mealworm Sorting Machine Have?
This machine integrates multiple functions into one system. The process flow is smooth and efficient, while a range of practical design features improve the overall operating experience.
Integrated Synchronous Operation
The machine follows a fully synchronized workflow. It is designed according to the logic of manure screening first, followed by skin removal and dust collection, and then mealworm sorting. It completes live mealworm grading, as well as separation of dead worms and pupae in one single process, without the need for secondary manual material handling.
Flexible Parameter Adjustment
All operating parameters can be freely adjusted. The speed of the dual-layer sorting belts and the airflow of the blower can be independently controlled. The mealworm grading section is equipped with a variable frequency system, making it suitable for different mealworm sizes and various sorting conditions.
Secondary Fine Sorting
The secondary sorting unit performs an additional screening process on the material. Lower-level mealworms are lifted and conveyed, while healthy mealworms are automatically returned to the main machine for re-grading. Pupae, dead worms, and impurities are uniformly conveyed to the color sorter.
Intelligent Color Sorting and Impurity Removal
The color sorter uses high-precision color sensors to accurately identify and remove black dead mealworms and various farming impurities, further improving the purity of the final product.
Enclosed Dust-Proof and Environmentally Friendly Design
The enclosed manure screening structure is equipped with dedicated collection bags. Mealworm skins and dust are all collected in a centralized manner, effectively suppressing dust emission and keeping the working environment clean and tidy.
Convenient Operation, Maintenance, and Mobility
The machine is designed for easy disassembly and maintenance. Manure screens and grading screens can be quickly removed and replaced. The dust-proof cover and control box of the main machine can be freely opened, allowing operators to observe machine operation status and perform routine maintenance conveniently. The system also features flexible site adaptability. The entire machine is equipped with swivel casters with brake functions, allowing it to be freely moved and fixed indoors without being restricted by workshop layout.


Suitable Materials
The Taizy Combined Mealworm Sorting Machine is mainly used for processing mixed mealworm materials. Suitable materials include large, medium, and small live mealworms at different growth stages, as well as mealworm manure, shed skins, pupae, naturally dead mealworms, and small amounts of farming impurities generated during the breeding process.
The machine is suitable for two major processing forms: fresh live mealworms and pre-dried mealworms. For raw materials containing vegetable leaves, fruit peels, and other materials that may easily cause blockage, the machine can be modified with an external blower to expand its material adaptability.
By replacing screens with different specifications, the machine can sort mealworms at all growth stages, from first-instar larvae to fully grown adult mealworms. This enables the equipment to cover the entire sorting process required for mealworm farming and primary processing operations.

How Does the Mealworm Sorting Machine Work?
Stage 1: Primary Separation (Main Unit)
Raw material enters the main separator where mesh screens remove frass and fine debris. Integrated fans extract shed skins and dust into collection bags. The dual-layer sorting belt separates larvae by size while preliminary separation distinguishes healthy larvae from pupae and dead insects.
Stage 2: Secondary Refinement (Secondary Unit)
Undersized or low-position larvae transfer to the secondary sorter for re-evaluation. Healthy specimens automatically return to the main unit for re-grading, while pupae, dead insects, and remaining debris convey toward the color sorter.
Stage 3: Optical Purification (Color Sorter)
High-precision color sensors identify and eject black dead larvae and residual impurities. This final purification step achieves over 99% separation accuracy under standard operating temperatures of 25°C and above.
