Q1: What is the main purpose of this equipment?
This equipment is a multi-functional screening platform. By replacing different functional kits, two core functions can be realized:

Pest detection: Separate live insects, dead insects, eggs, and debris from grain samples;

Grain grading: Assess grain purity, grade, and particle size distribution based on particle size. One machine for multiple uses, saving costs and space.

Q2: How to switch between pest detection and grain grading functions?
 Switching is very simple and fast:

• When performing pest detection: Install a sieve kit with a fine mesh screen at the bottom (e.g., 0.5mm-2.0mm aperture) and a transparent collection pan.

• when grading grains: Install a grading sieve kit configured according to official standards (such as GB, USDA) (usually including multiple layers of sieves with different apertures).

• The entire process only requires changing the sieve sets; the main unit platform is completely universal.

Q3: How to choose sieves for different grains (e.g., wheat, rice, corn)?

• For pest detection: We providePest detection specialized sieve kit, its aperture is carefully designed to effectively separate most common storage pests, suitable for various grains, and has strong versatility.

• For grain grading: We offerGrading sieve kit compliant with international standards(e.g., specialized kits for wheat inspection). You need to select the corresponding kit based on the type of grain to be tested and the inspection standards to be followed. Our product catalog provides a detailed selection guide.

Q4: Is the vibration mode of the equipment optimized for different functions?

 Yes. Our high-end electric models may offerAdjustable vibration frequency and time settings.

• Pest detection mode: It is recommended to use a higher frequency and longer duration (e.g., 10 minutes) to ensure that tiny pests and debris can be effectively separated into the collection pan.

• Grain grading mode: Usually use standard frequency and shorter duration (e.g., 5 minutes) to achieve clear particle size stratification.

• (Note: Basic manual or single electric models ensure effectiveness through fixed operating procedures.)

Q5: How to ensure the accuracy of detection after switching functions?
Accuracy originates from three aspects:

Precision of specialized kits: Each sieve kit is specially calibrated and certified for its function;

Host stability: The host provides uniform and consistent vibration, ensuring repeatability of each operation;

Standard operating procedures: Follow the Standard Operating Procedures (SOPs) we provide for each function.

Q6: What should be noted during cleaning?

Extremely important! When switching functions, especially fromSwitching from pest detection to grain grading, the equipment must be thoroughly cleaned. Use a soft brush to clean the sieves and platform to prevent residual pests from contaminating the next sample and affecting the purity assessment results. It is recommended to equip independent cleaning tools for different functional kits.
