APEX Double-Layer Belt Sorter for Crop Wheat Impurity Removal

Features of APEX Double-Layer Belt Sorter

The Model DL double-layer belt sorter is custom-developed for large-volume, high-throughput industrial grain processing. It features an independent dual-layer belt layout that forms two separate sorting stations to implement secondary deep precision screening for bulk grain raw materials.

1. Dual-layer staged purification process

Raw grains first go through preliminary impurity separation on the first conveyor belt. The preliminarily screened materials are then delivered to the second sorting station for intensive re-inspection, thoroughly clearing micro residual impurities and omitted defective grains that single-layer sorting equipment cannot completely filter out.

2. Massive throughput for heavy-duty continuous production

Dual-path synchronous optical detection significantly boosts hourly processing capacity and full material inspection coverage. This design reliably satisfies long-duration, high-load running requirements of large centralized grain processing production lines.

3. Wide compatibility for full-spectrum grain varieties

It supports mass purification for mainstream grain varieties including rice, assorted beans, crop seeds, dried fruits and commercial coffee beans, enabling unified standardized bulk processing for diversified grain materials.

Model DL double-layer belt sorting equipment empowers large grain manufacturers to realize high-efficiency, high-purity standardized mass production, steadily lifting finished product qualification rate and overall factory operational efficiency.

Working Principle of APEX Double-Layer Belt Sorter

Step 1: Lossless Belt Feeding & Primary Sorting
Mixed grain raw materials fall into the feeding hopper and are uniformly distributed onto the first-layer horizontal conveyor belt by the feeding vibrator. The upper CCD detection module identifies and removes large impurities and obvious defective grains at the first sorting station. Severely defective materials are directly ejected into the rejected product hopper, while preliminarily purified grains drop down to the second conveying belt.
Step 2: Secondary Deep Precision Screening
Materials enter the second independent sorting station along the lower belt. The second group of camera and light source system performs high-density fine scanning to capture tiny residual impurities and minor flawed grains missed in the first sorting. Slightly defective grains are blown into the recycle hopper for reprocessing.
Step 3: High-purity Finished Product Collection
Grains passing two rounds of optical inspection are stably conveyed to the outlet and fall into the accepted product hopper. The two-stage belt sorting mode achieves thorough grain purification, adapts to high-volume continuous production of large grain processing plants, and avoids grain breakage during the whole conveying process.

Performance Comparison

Sorting Performance for Bulk Chinese Herbal Medicines

• Qualified Finished Herbs: Complete texture, uniform natural color, free of mildew, oxidation discoloration and broken fragments. The lossless belt conveying avoids fragmentation of brittle herbal slices and granular medicinal materials in mass continuous production.
• Rejected Defective Materials: Moldy pieces, rotten residues, stained fragments and foreign impurities are firstly intercepted by the first-layer sorting station; subtle residual flaws that escape primary screening are completely eliminated by secondary high-precision detection on the second belt.

DL double-layer staged purification greatly improves the finished product purity of bulk Chinese herbal medicine processing, effectively lifting the qualification rate for large-scale medicinal material deep processing manufacturers.

Applicable Sorting Materials

Supported by independent double-layer belt sorting stations, the DL sorter performs primary rough impurity removal plus secondary precise fine screening, specially developed for mass raw material pretreatment in large processing factories.

1. Bulk Grain Products
   Rice, assorted beans, grain seeds, dried fruits, coffee beans and other conventional granular agricultural commodities. Dual-channel synchronous detection raises hourly processing capacity to satisfy long-term high-load assembly line production demands for grain deep-processing enterprises.
2. Various Chinese Medicinal Materials
   Ginseng slices, astragalus, poria cocos, alisma orientale, coptis root, cape jasmine fruit, peach kernels, lily bulbs and other sliced & granular herbal raw materials. Soft belt transportation prevents brittle herbal pieces from cracking, while secondary screening thoroughly clears residual moldy scraps, discolored fragments and mixed foreign impurities left after primary sorting.
