A three-machine compact process line for drying, grinding, and iodizing moist salt: 4 m stainless steel rotary dryer, 50 cm vertical stone mill, and iodine dosing unit.
Investment Rationale
The smallest comprehensive line that converts moist raw salt into iodized table salt. The investment threshold is low, and the number of equipment is few; it is an entry-level production step for import substitution in the region.
Scope of Work
- 4-meter stainless steel rotary salt dryer (18 kW electric heater, speed-controlled mixer)
- 50 cm vertical stone mill (11 kW, salt/grain/bulgur)
- Iodine dosing and homogeneous mixing unit (screw-fed)
- Stainless steel inlet/outlet hoods and insulation
- Industrial painted carrier chassis and polyurethane wheels
Key Findings
Drying → grinding → iodination; grinding and iodine distribution remain unstable without moisture removal.
Dryer electric heater power; can be activated without requiring fuel infrastructure.
All surfaces in contact with the product are stainless; a decisive choice against the corrosive effect of salt.
The mill crushes grains and bulgur in addition to salt; the facility may expand its product range in the future.
Investment Budget
Approximate investment ranges by equipment group. These are grouped estimate bands, not line-item prices.
There is no item breakdown in the sourcing work; the total amount has been converted into a band.
Excluded from this budget
- Transportation and shipping insurance
- Customs clearance and local taxes
- Building, infrastructure, and electrical line
- Travel and accommodation expenses of the assembly team
The price range is based on the 2021 study and is EXW; the current amount varies according to the specification, exchange rate, and delivery conditions.
Subject of the Study
A compact process line was developed for a food producer operating in West Africa, which converts raw salt into **food-grade iodized table salt**. The line consists of three stages: drying, grinding, and iodizing.
Why these three stages
In the region, salt is mostly supplied with high humidity. Moisture disrupts both grinding and packaging; it also prevents the homogeneous distribution of the iodine additive. Therefore, the sequence was established as **first drying, then grinding, and finally iodizing**.
Equipment Approach
The dryer is of the rotary type with a 4-meter body and a 7-degree incline; the material and hot air enter from the high side, and the product moves forward by its own weight. The body is made of 2 mm AISI 304 stainless steel, and the outer surface is insulated with 50 mm glass wool — this detail reduces energy consumption and keeps the outer surface temperature safe.
A vertical stone mill has been preferred in the grinding stage; since the same machine can also be used for grain and bulgur crushing, the possibility of expanding the product range of the facility remains open in the future.
Limit of this Study
The source study is an **equipment proposal**; it does not include plant capacity (tons/day), building layout, and operating cost. This page only contains the equipment scope and investment range.
Assumptions & Limitations
This study was prepared under the assumptions below. Results will differ under other conditions.
- Capacity
- The ton/day capacity is not specified in the source study; equipment dimensions are provided on this page, no capacity estimation has been made.

Why is capacity not written?
The source study is an equipment offer and does not include ton/day capacity. We do not estimate and publish a figure that we do not have; capacity calculation is made on a project basis according to product moisture and working hours.
Is the price current?
No. The price is based on the 2021 study. It is sufficient to open a request for the current amount; it will be re-priced according to the specification and delivery conditions.
Can only one machine be purchased?
Yes. The three stages complement each other but can also be procured separately; if an addition is to be made to the existing facility, the scope will be narrowed accordingly.
