The Use Of Evaporators In The Food Industry

The evaporators are used for accomplishing the process of evaporation. The process of evaporation has been utilized in various industries for various purposes. If we talk about the usage of the evaporation process in the food processing industry then, the products of food are concentrated with the help of the evaporators, so that the shelf life of the products increases. It also helps in reducing the weight and volume of the food products. As a result, the cost of the storage of food products reduces, the cost of transportation also reduces, and consequently, the value of the food products increases. During the harvest period, it is very important that the biodegradable crops should be used economically and the evaporators help in doing so. 

One of the examples of this is the production of fruit juices, which is produced by the concentration of fresh fruits with the help of evaporators. 

Every item of the food has its seasons and they can’t be consumed for the whole year. However, with the help of the evaporators, fresh fruit juices and tomato paste are the biggest examples of the food items which can be consumed throughout the year. The evaporators are also used for the preservation of the concentrated food through following the process of microbiological stability and lowering water activities. If we talk about the use of the evaporators in the industries of kraft paper and chemical, then the process of evaporation is used for the chemicals which are nonvolatile. 

The evaporators help them to recover and make them valuable again. For example, if we talk about the process of kraft pulping, then the water remaining in the spent cooking liquid gets evaporated and the concentration of the solid happens. The spent cooking liquid is also known as black liquor. The chemical which has just concentrated in the process, then finally becomes refined and can be reused easily. When it comes to the industry of pharmaceuticals, the process of evaporation is used for concentrating the solution. The concentrated solution than further dried out so that it can become a powdered product. The use of evaporators is very common in various industries.

However, when it comes to the food industry, the evaporators are best suited in various applications of the food industry. There are basically three types of evaporators that are commonly used in the food industry, such as plate type evaporators, forced circulation evaporators, and long-tube vertical evaporators. All three evaporators are used for different applications in the food industry. For example, long tube evaporators which are also called the falling film evaporators are used in the concentration of the food items which are heat-sensitive, such as milk and fruit juices. Whereas, forced circulation evaporators are commonly used for the concentration of viscous and pulpy liquids such as mango juice and tomato juice.

Crystallizers and its applications

The process of crystallization is also called the process of forming snow. The process of crystallization is a chemical reaction through which the crystals are formed. The process of crystallization involves the purification of the compound and the identification of the chemical characters. The drug was also discovered with the process of crystallization and all the drugs in the world are made up of following the crystallization process. If we talk about the detailed crystallization process through crystallizers, then it involves a decrease in temperature inside the crystallizers. As the temperature decreases, the process of dissolving the solvent also slows down and decreases.

This stage is called the supersaturation of the solvent. Due to the supersaturation procedure, some molecules are released and bond together. The molecules that bond together form a crystal. After the formation of the crystals happens, the crystallization process is completed. The molecules which bind together and form crystals are usually purer than the molecules which couldn’t form the crystals. The molecules which didn’t form the crystals, go back to the original solution itself. Whereas, in some of the cases, when the process of cooling down doesn’t happen properly, then the molecules go back to the liquor and leave the crystal. The process of crystallization is very simple and can easily be done through the crystallizers.

The common examples of crystallization in our day to day lives are the formation of snow, which is actually the crystallization of water and the process of salt harvesting. However, the industrial process of crystallization involves other scientific things and equipment as well. The basic concept of the crystallization process includes, the temperature of the solution should be increased first. So, the process of evaporation happens and the compounds of the solution should be crystallized. The increased temperature should remain the same till the time, no solid substance is left in the solution. The next step is to decrease the temperature of the solution slowly and steadily while keeping the solution in the static form.

As we discussed above, this step is also called supersaturation. When the supersaturation process is completed, the crystals are formed. Separate the crystals from the solution, isolate them, and let them dry in the natural process. When it comes to the application of the crystallization process, then one of the most common usages of the process of crystallization is the production of salt. The salt produced through the crystallization process is called salt crystallization. Other applications through the crystallization process are the production of the crystals and the purification of the compound. Some chemicals are also produced with the help of the process of crystallization, one of the most common examples is chemicals of salt powder. The crystallization process is also used as the production of food additives on a larger scale.
