In the date processing industry, companies of varying sizes and production regions face diverse processing needs. These range from the physical properties of date varieties (such as Iraqi honey dates, Dubai golden dates, and Iranian black dates) to production capacity tiers (ranging from 5 to 50 tons per day) to individual quality standards for finished products. These requirements create non-standard adaptation requirements for grading equipment. The JCSORT date grader, with its fully modular, customizable design and four core customizable units: an elevator, brush spray cleaning, fan drying, and roller size grading, provides precisely tailored processing solutions for global customers, particularly those in the Middle East's major producing regions. It has become the preferred equipment for date processing companies in the Middle East.

1. The Core of Customization: From Demand Research to Module Adaptation, Achieving "One Machine, One Factory"

Customization of the JCSORT date grader goes beyond simple parameter adjustments; it encompasses a comprehensive, integrated process encompassing "demand diagnosis - solution design - module production - on-site commissioning - and after-sales optimization." Addressing the three key concerns of Middle Eastern customers: thorough cleaning, grading accuracy, and capacity matching, the equipment breaks down the four functions of elevator, cleaning, air drying, and grading into independently customized modules. Customers can flexibly select module combinations and technical parameters based on their specific processing flow (e.g., whether pre-treatment cleaning is required, grading level requirements, and workshop layout dimensions). This ensures seamless integration of the equipment with existing production lines, avoiding resource waste caused by overkill or overloading a small machine.

II. Detailed Explanation of the Four Customizable Modules: Precisely Addressing the Complete Date Processing Process

(I) Elevator Module: Adapting to Production Capacity and Workshop Layout for Efficient Material Feeding

As the first conveying checkpoint in date processing, the JCSORT elevator module can be deeply customized based on the customer's daily production capacity and workshop layout. Core customization dimensions include:

Conveying Efficiency Customization: Targeting the "large-scale processing" needs common among Middle Eastern customers, the elevator conveying speed is adjustable between 0.5m/s and 2m/s. A single elevator can transport 1,000kg to 3,000kg of dates per hour. For customers requiring multiple processing lines, a multi-export elevator can be customized, enabling "one machine to serve multiple lines" and meeting daily processing capacity requirements exceeding 20 tons.

Material and Structure Customization: Considering the sticky skin of some Middle Eastern date varieties (such as Iranian black dates) that easily retain impurities, the elevator conveyor belt can be made of either food-grade 304 stainless steel mesh or PU soft belt. The stainless steel mesh belt facilitates subsequent cleaning fluid penetration (when integrated with the cleaning module), while the PU soft belt allows for easy cleaning. Soft belts can reduce skin damage and can be selected based on the characteristics of the date palm variety.

Customizable lifting height: The elevator's lifting height can be customized between 1m and 5m based on the customer's workshop feed inlet height (e.g., a raw material silo 1.5m or 3m above the ground). The elevator also supports adjustable tilt angles (30°-60°) to accommodate different workshop layouts, eliminating installation and modification costs due to equipment sizing issues.

(II) Brush Spray Cleaning Module: Customizable Cleaning Intensity, Balancing Cleanliness and Integrity

Middle Eastern customers have extremely high requirements for the cleanliness of finished date products—not only do they need to remove surface dust and sand, but they also need to remove residual juice from the date stems to prevent subsequent adhesion. The JCSORT brush spray cleaning module achieves "high-efficiency cleaning with low waste" through a triple-customized design:

Brush Customization: Brush materials include soft nylon brushes (suitable for golden dates with delicate skin) and medium-hard DuPont silk brushes (suitable for candied dates with thicker skin). Brush density is customizable (100 to 300 bristles/cm²), and brush speed is adjustable (500-1500 rpm), ensuring robust cleaning without scratching the date skin.

Spray System Customization: Spray pressure can be adjusted from 0.2MPa to 0.8MPa For customers in the Middle East using groundwater (containing minor impurities), a pre-filtration module (50-200 mesh) can be customized to prevent clogging of the spray holes. Multi-stage spraying is also supported: an initial high-pressure rinse (to remove sand), a mid-stage warm water soak (to remove sticky impurities), and a final clean water rinse (to remove detergent residue). Customers can select the number of spray stages based on the type of impurities.

Customized residue handling: The bottom of the cleaning tank can be customized with a sloped residue collection trough, equipped with an automatic scraper device to remove fallen fruit pomace and sand during the cleaning process, preventing residue accumulation and contamination of the dates and reducing the need for manual cleaning.

(3) Fan Drying Module: Customize drying parameters to avoid "over-drying and cracking" or "over-wetting and sticking."

Excessive moisture in the dates after washing can cause them to stick to the rollers during grading, affecting grading accuracy. Over-drying can cause the dates' skin to crack, reducing their value. The JCSORT fan drying module offers precise customization based on the moisture tolerance of different date varieties:

Air temperature and speed customization: The drying temperature can be adjusted between room temperature (25°C) and 60°C (low temperature is suitable for fresh dates, medium temperature is suitable for semi-dried dates). The wind speed can be switched between 5m/s and 15m/s. It also supports "staged drying"—strong air in the front section removes surface moisture, while weak air in the back section removes interstitial moisture, ensuring the final moisture content of the dates is controlled at 15%-20% (a standard commonly used by Middle Eastern customers).

Drying time customization: The drying channel length can be customized between 1m and 5m based on the customer's production line speed. Combined with adjustable conveyor belt speed, precise drying time control from 10s to 60s is achieved, avoiding grading delays caused by delayed drying.

Energy-saving design customization: Designed for the high-temperature and energy-intensive production environments of the Middle East, a heat pump recovery system can be customized to recycle the hot and humid air generated during the drying process, reducing energy consumption by approximately 20%, in line with customers' long-term operating cost control needs.

(IV) Roller Size Grading Module: Customizable Spacing Accuracy for Multi-Level Precision Sorting

As the core execution unit for date grading, the JCSORT roller size grading machine achieves grading through dynamic variations in roller spacing. Its degree of customization directly impacts the accuracy of the finished product. Key customization highlights include:

Customizable Grading Levels and Spacing: Based on customer-defined finished product size requirements (e.g., the four-level grading commonly used by Middle Eastern customers: "Special Grade (≥50mm), Grade 1 (40mm-50mm), Grade 2 (30mm-40mm), and Grade 3 (≤30mm)"), roller spacing can be precisely customized between 5mm and 60mm, with an adjustable accuracy of ±0.1mm, ensuring a consistent grading accuracy of over 99.5%;

Customizable Roller Material and Structure: The rollers are precision-machined from food-grade 304 stainless steel with a matte finish to prevent slippage. Variable-diameter rollers are also supported. Customization (for oval dates) ensures smooth conveyance of dates of varying shapes along the roller axis, preventing grading errors caused by rollover.

Linked control customization: This system can achieve "linked speed regulation" with the preceding cleaning and drying modules. When the roller detects accumulation of dates, it automatically reduces the conveying speed of the elevator and cleaning module to prevent overload. It also supports linkage with the subsequent packaging line, allowing graded dates of different grades to be directly delivered to the corresponding packaging station, reducing manual transfer steps.
