How is it manufactured

In the production industry, ice block making is one of the top runners since it is needed for restaurant businesses, fishing and agriculture. That is why there are now a lot of ice block manufacturers to accommodate the demands for the product. 

In India, Ice Block Making Machines are popular because the demand for the machine continues to grow. However, not a lot of people, especially consumers, are aware of the process of ice block making. With that being said, here is a brief yet informative step-by-step process of ice block manufacturing:

  1. Considering the materials

Before creating ice blocks, manufacturers would first consider their location and the body of water near them. Although most of the time, most manufacturers would use seawater because it is the most abundant resource of water. 

  1. Cleaning and checking the water quality

Since most ice blocks are used for food preservation, all manufacturers would take the extra effort to ensure that the water is clean. This means that it is free from contamination, which will keep the food away from any degradation. 

  1. Filling up the cans

Once the seawater resource is cleared from inspection, the manufacturers will now fill their iron cans with it. Afterwards, these containers will be submerged in brine, which is a mixture of water, sodium or calcium chloride. This will then be refrigerated below freezing water. After a couple of hours, the cans will be removed from the brine, and then the frozen blocks of ice will be removed from the cans. To release the ice blocks, the cans will be submerged in freshwater.

  1. Storing the ice blocks

After removing the ice blocks from the can, all ice blocks will be transferred to a large freezer container. This is the place where the ice blocks are stored and removed upon processing an order.

  1. Using ammonia for large scale ice block production

In a larger scale production, manufacturers would use ammonia as a key ingredient to speed up the process of ice block making. This gas will be pressurised and subjected to cold temperatures to release its liquid form. Once it reaches that state, the liquid will then be added to the sides of the cans, which will, later on, add a chilling effect.

The uses of ice blocks

Ice blocks have multiple purposes, which makes them an important commodity in the market. Here are some examples below to give you an idea of ice block uses:

Preserving food and beverages

Ice is a great tool in preservation because it keeps food fresh. This will prevent the raw ingredients from composting and extend their shelf life. Aside from that, ice blocks do great in keeping drinks cool to beat the heat.

Ice sculpture

Ice sculptures are common during winter because this is the time when they will not melt out in the open. That is why multiple art exhibitions would hold ice sculpture events for people to enjoy.
