Production line and factory setup overview
A small food-processing line converting food-grade released rock salt into iodised table salt through lot receiving, pre-cleaning and foreign-matter removal, stainless crushing, screening, optional washing and centrifuging only when feed purity requires it, controlled drying, anti-caking and potassium-iodate solution preparation, calibrated iodine spraying and blending, metal detection, iodine verification, hygienic weighing, sealing, coding and carton packing.
Recommended lowest-entry line configuration Before selecting a dry or wash route, test several mine lots for NaCl, insolubles, calcium/magnesium, sulfate, heavy metals and microbiology. For clean food-grade rock salt, screen a 300-500 kg/h dry line with stainless crusher, two-deck sieve, small dryer only if needed, batch iodiser/blender, metal detector and 500 g/1 kg packer. Contract iodine at production and shelf-life limits with Afghan health authorities.
Production process and implementation sequence
- Mine-lot receiving, sampling and food release
- Pre-cleaning and foreign-matter removal
- Stainless crushing and two-stage screening
- Optional washing, centrifuging and drying
- Iodate solution preparation and calibration
- Iodine spraying, blending and conditioning
- Metal detection and iodine verification
- Weighing, sealing, coding, cartoning and dry storage
Products, capacity and market fit
- Afghan rock salt can become a basic public-health food product when purity and iodine are controlled.
- A dry route avoids unnecessary water and energy where mine salt already meets chemical cleanliness.
- Two retail sizes simplify film, settings, laboratory release and distribution.
- Food licensing, potable water, iodate control and traceability are essential—not optional machinery extras.
- Iodised table salt - Afghan legal NaCl, iodine at production/shelf life, moisture, insolubles, contaminants and pack weight - Household retail, wholesalers and institutional food buyers
- Food-processing salt - Separate granulation, iodine and pack specification - Bakeries, dairy, pickling and food manufacturers
