5 most popular types of salt

Kosher salt – It is a coarse-grained flaky salt. it’s generally less pungent than table salt and dissolves easily.

Table salt – This is the most common type of salt, and the one most used in home kitchens. This is sourced from salt mines; it is then refined, and most minerals removed. Anti-caking agents

Sea salt – Sea salt refers to unrefined salt that is sourced from the sea. It is collected by the evaporation of sea water. The lack of refinement in sea salt means that it will still contain traces of other.

Coarse salt – Coarse salt simply refers to a large-grained salt crystal. Therefore, it can be both a sea salt or a mined salt. It tends to retain less moisture, so caking doesn’t occur, even without the introduction of anti-caking agents.

Bath salts – Bath salts, which are commonly made from magnesium sulfate (Epsom salt) or sea salt, are easily dissolved in warm bath water and used for everything from stress relief to aches and pains.

What is iodine?

Iodine is a mineral found in the food we eat. It is absorbed from the soil into the plants that form part of our daily diets. It is an essential mineral playing a role in important processes within the human body. Iodine forms part of the thyroid hormones, which are essential for normal physical and mental development.

Why do we need to iodate salt?

Most of the world’s iodine is found in our oceans, although it is also present in soil. Over the centuries, large amounts of iodine have been leached from surface soil by rain and carried back to the sea. Iodine then returns to the soil via rainfall after being absorbed into the atmosphere from the sea’s surface, but this process is very slow.

Repeated flooding of areas also increases the depletion of iodine from the earth. Crops grown in these areas therefore often lack iodine, and as a result, people who are dependent on food grown in iodine-poor soil become iodine deficient.

When goitres and brain damage are caused by lack of iodine, they can be cured in the early stages by large doses of iodine

What are the key considerations when selecting salt packaging equipment?

While there are many fundamental determinants to packaging salt, we pay close attention to the following: Salt is a substance that causes metal corrosion at high humidity levels, this means that the manufactured machines should be composed of corrosion-resistant stainless steel. Salt has hygroscopic properties, it can from lumps if moisture is present. Excessive product transportation can grind the salt affecting particle size and introduce fine dust.

We recommend a flip flop volumetric filling system opposed to a rotary volumetric filling system to minimise grinding the product and promoting dust.

What sizes of salt can we package?

Our Vertical-form-fill-seal machines can package salt into the weight range of between 50g – 25kg.

Our Stickpack machines can package salt into the weight range of between 6g – 20g.

Our Sachet machines can package salt into the weight range of between 10g – 40g.

What types of packaging machines can we package salt with?

Semi-automatic with premade pouches.

Fully automatic in 4-sided seal paper and 3-sided seal pillow pack or gusseted bag format.

Bottles and shakers.

What are the most popular types of material used for packaging salt on our range of machines?

Vertical form, fill and seal 3 sided seal –Polyethylene/LDPE

Stick pack 3 sided seal–Poly-coated paper

Sachet 4 sided seal – Poly-coated paper

I want to purchase a machine that packages salt.

We suggest a fully automatic system that can quickly and efficiently pack salt and is a cost-effective system with a high production rate. A semi-automatic system can also be used which would suit a smaller budget but has a much lower production rate. Semi-automatic systems can also be intergrated into a fully automatic system at a later stage. When moving from semi-automatic to fully automatic you will save 20 to 25% on your material costs not to mention labor and production output.
