Top Cloud-agri SLY-C Plus Automatic Seed Counter

Overview

The Top Cloud-agri SLY-C Plus Automatic Seed Counter is an electromechanical counting instrument engineered for high-throughput, repeatable enumeration of agricultural seeds in research, breeding, quality control, and seed certification workflows. It operates on a vibration-assisted single-layer dispersion principle: seeds are fed into a vibrating hopper, evenly distributed across a transparent counting channel via controlled oscillation, and optically detected using a high-sensitivity photoelectric sensor array. The microprocessor-based control system processes real-time pulse signals generated by seed passage, enabling deterministic counting without mechanical contact or image analysis—ensuring robust performance under variable ambient lighting and with heterogeneous seed batches. Designed specifically for agronomic laboratories, it replaces manual counting in standardized procedures such as thousand-kernel weight (TKW) determination (ISO 6558, ISTA Rules), germination testing preparation, seed lot sampling, and precision sowing calibration.

Key Features

• Microcontroller-driven operation with tactile membrane keypad and 128×64 dot-matrix LCD display for real-time monitoring of count value, preset target, elapsed time, vibration speed level, and system clock.
• Seven-step adjustable vibration intensity—calibrated to accommodate seed diameters from 1 mm (e.g., lettuce, poppy) to 12 mm (e.g., large maize kernels or legume seeds)—minimizing bridging, clumping, or double-counting artifacts.
• Programmable auto-stop function: user-defined count threshold (1–99999) triggers immediate cessation of vibration and audible alert, ensuring batch integrity and eliminating over-counting.
• Intelligent idle detection: system automatically suspends vibration when no seed transit is registered for >3 seconds, reducing mechanical wear and power consumption while extending service life.
• Low-noise operation (≤70 dB[A] at 1 m distance) compliant with ISO 7779 and EN ISO 3744, suitable for shared laboratory environments including teaching labs and QC rooms.
• Integrated acoustic feedback: distinct beeps confirm count completion, idle shutdown, and error conditions (e.g., jam detection or sensor obstruction).
• Dual-voltage universal power input (110 VAC/60 Hz and 220 VAC/50 Hz) with internal voltage regulation ensures stable operation across global field stations and international partner labs.

Sample Compatibility & Compliance

The SLY-C Plus accommodates dry, free-flowing seeds within the 1–12 mm diameter range—including cereals (wheat, rice, barley), oilseeds (rapeseed, sesame, sunflower), pulses (soybean, lentil), and horticultural species (tomato, pepper, cabbage). Surface texture, aspect ratio, and moisture content (<14% w.b.) influence optimal vibration setting selection; users are advised to perform a 50-seed validation run prior to formal TKW or germination sub-sampling. The instrument complies with ISO 6558:2022 (Cereal grains — Determination of thousand-kernel mass), ISTA Handbook Chapter 5 (Sampling), and national standards GB/T 3543.3–1995 (Crop seed testing rules – Purity analysis). Its non-destructive, contactless counting mechanism supports GLP-aligned documentation when paired with external lab notebooks or LIMS-integrated logging.

Software & Data Management

The SLY-C Plus operates as a standalone embedded system with no proprietary software dependency. All operational parameters and count logs are retained in volatile RAM during active use and persist across power cycles via EEPROM-backed memory. Timestamped count records (date, time, preset value, actual count, speed level) can be manually transcribed or exported via optional RS-232 serial interface (available on request) for integration into Excel-based QA templates or validated LIMS platforms. While the device does not support FDA 21 CFR Part 11 electronic signatures natively, its deterministic counting algorithm, audit-ready parameter history, and physical logbook compatibility enable alignment with GxP data integrity requirements when deployed under documented SOPs.

Applications

• Thousand-kernel weight (TKW) determination per ISO 6558 and national seed grading protocols.
• Pre-germination seed sub-sampling for viability and vigor assays (ISTA, AOSA).
• Quality assurance in seed processing lines—batch verification before packaging or certification.
• Field trial setup: precise allocation of uniform seed quantities per plot or treatment.
• Educational use in plant science curricula for hands-on seed morphology and biometry labs.
• Grain trading labs performing rapid lot reconciliation and contract compliance checks.

FAQ

What seed types are compatible with the SLY-C Plus?
The instrument is validated for dry, non-sticky seeds ranging from 1 mm (e.g., carrot, tobacco) to 12 mm (e.g., large maize, pigeon pea). Avoid use with freshly threshed, high-moisture, or heavily dust-coated seeds without prior drying and cleaning.
How is counting accuracy verified?
Users should conduct periodic verification using a known reference sample (e.g., 100 certified seeds counted manually under magnification). Deviation exceeding ±0.2% warrants re-calibration of vibration level or inspection of sensor window cleanliness.
Does the device require routine calibration?
No factory calibration certificate is supplied, as the counting mechanism relies on optical pulse detection rather than force or mass transduction. However, daily functional checks using a 50-seed test batch are recommended per ISO/IEC 17025 Clause 7.7.
Can the SLY-C Plus integrate with laboratory information management systems (LIMS)?
Yes—via optional RS-232 output (firmware v2.3+), enabling ASCII-formatted count records to be ingested by third-party LIMS or custom Python/Excel automation scripts.
Is the unit suitable for humid or outdoor environments?
It is rated for indoor laboratory or climate-controlled storage room use only (operating RH <85%, non-condensing). Not IP-rated for dust or water ingress; avoid deployment in unsheltered field tents or grain silos.
