Raisins Manufacturing Process Flow

Grape Harvest Washing Pre-treatment Drying Process Sorting & Grading Packing
Manufacturing Process: Each arrow indicates process step transition.
  1. High-sugar grapes are selectively hand-harvested at target brix levels (17.5–19° Brix).
  2. Grapes undergo triple-stage washing (ISO 22000/FDA-compliant water filtration).
  3. Pre-treatment (thermal/alkaline, FDA-approved): Raises skin permeability for uniform drying.
  4. Drying (sun, tunnel, or mechanical, controlled at 48–60°C for 18–36h), with mean residual moisture 15–18%; inline sensors track process.
  5. Sorting & Grading: Color/size analysis with optical sorters, manual spot-checking, and metal detection.
  6. Packing: Modified-atmosphere packaging extends shelf life to 18–24 months.
  • Compliance standards: ISO 22000, FDA, GFSI–audited supply chain, traceability enabled.
  • Metallurgy (machines/components): 304 SS for all contact surfaces ensures food safety.

Custom Solutions & Innovations for Raisins Supply

  • Material selection: Only A-grade seedless varieties (e.g., Thompson Seedless, Flame Seedless) are promoted for premium-grade Raisins to guarantee desired granularity and sweetness.
  • Manufacturing: Use of automated continuous tunnel dryers and CNC-precise sorting machinery (color, size, foreign matter) reduces human error and ensures compliance with Codex Alimentarius standards.
  • Testing & QC: Metal detectors, automated moisture analyzers, and batch sampling strictly per ISO/IEC 17025 for food safety.
  • Customization options: Sulphur-free, organic, variable brix, bulk or small pack, private labelling, and packaging setting (MAP, nitrogen flush).
  • Delivery & lead times: Bulk: 7–15 working days; custom pack/private label: 17–28 days. Express Air & Reefer Container available.
  • Guarantees: Full batch traceability, up to 24 months shelf life under cool/dry storage, and international certificates provided with shipment.

Superior Performance in Typical Application Scenarios

  • Baking Industry: Controlled moisture content delivers chewy texture, no post-baking browning; compliant with EU EC Regulation 1881/2006 for contaminants.
  • Snack Foods: Shelf stability & nutritional integrity due to low water activity and nitrogen-packing.
  • Dairy Inclusions: Sulphur-free Raisins prevent discoloration in yogurt and ice cream mixes.
  • Pharmaceuticals: Used as natural sweetener & fiber enrichment in nutraceuticals (ISO/FDA listed).
  • Processed Meats/Industrial: Antioxidant properties extend shelf life of food emulsions.
Third-party tested for heavy metals (ICP-MS, per ISO 17025).

Technical Advantages

  • Corrosion Resistance: Only food-contact parts are 304/316L stainless steel—ensuring anti-corrosive durability over 10–15 years (factory data).
  • Energy Efficiency: Modern dryers cut energy use by 21% (peer-reviewed:Science Direct).
  • Precision: CNC-automated grading produces ±4% uniformity in size distribution v. ±11% in manual processes.
  • Shelf Life: Modified atmosphere increases shelf life from 10 to 24 months.
