FRY-TECH FOOD EQUIPMENTS PVT LTD Make Dry Fruit Grader is an advanced machine used in the food processing industry to automatically and consistently sort dry fruits (such as cashews, almonds, raisins, walnuts, dates, apricots, and pistachios) based on various quality parameters.Its primary purpose is to ensure product uniformity, which is critical for packaging, quality control, and market pricing, while significantly reducing the time and inconsistency of manual sorting. Core Grading PrinciplesDry fruit graders primarily utilize two main types of technology, often integrated into a single system:1. Size/Weight Grading (Mechanical Grading)This method separates the dry fruits based on their physical dimensions or mass.* Sizing by Screens/Sieves: For products like groundnuts or small nuts, perforated screens or sieves with specific aperture sizes are used. The machine vibrates, causing smaller pieces to fall through the screen into one collection bin, while larger pieces move on to the next, graduating them by size.  * Sizing by Diverging Rollers: This is common for elongated or round items like dates or large almonds. Two parallel rollers move away from each other, creating an expanding gap. As the fruit travels along, it drops into a chute when the gap size matches its width.* Weight Grading (Load Cell): Highly accurate graders use load cells (precision weighing sensors) embedded in individual carriers or cups. The dry fruit is weighed as it moves, and at a programmed discharge point, a mechanism opens the carrier to drop the fruit into the corresponding grade bin.  2. Quality/Color Grading (Optical/Vision Sorting)This is the most critical and complex part, used to detect defects and color variations.* High-Resolution Cameras (RGB & Infrared): The dry fruits are fed onto a high-speed conveyor or chute, and high-definition cameras capture images of them from multiple angles (e.g., 360-degree vision systems).  * Image Processing Software: Advanced algorithms, often utilizing Artificial Intelligence (AI) and Deep Learning, analyze the images in real-time. They compare the captured features (color, shape, surface texture) against pre-set acceptance criteria.  * Defect Detection: The system detects undesirable items such as:* Off-colors: Too dark, too light, or moldy pieces.* Foreign Materials: Stones, shells, sticks, or unwanted foreign seeds.  * Physical Defects: Broken pieces, insect damage, or cracks.  * Ejection System: When a defective item is identified, a set of high-speed, precision air jets (pneumatic ejectors) is activated. These jets fire a burst of compressed air at the exact moment the defective piece passes the nozzle, diverting it into a rejection chute, while the accepted product continues to the main output.
Applications and BenefitsApplications (Products Handled)* Nuts: Cashews, Almonds, Walnuts, Pistachios, Hazelnuts.* Dried Fruits: Raisins (Kishmish, Sultana, Currants), Dates, Dried Apricots, Prunes.  * Pulses/Grains: Used in similar systems for beans and coffee.Key Benefits1. Uniform Quality: Achieves superior quality consistency compared to manual labor, meeting international standards.2. Increased Speed & Throughput: Handles large volumes (often several tons per hour) far faster than human operators.3. Cost Reduction: Lowers labor costs and reduces human errors.  4. Maximum Yield: Many systems can re-sort the rejected product to salvage slightly lower-grade but still usable pieces, minimizing waste.5. Hygiene: Constructed from food-grade Stainless Steel (SS 304 or SS 316), ensuring sanitary processing.
