The advancement of technology carries with it numerous benefits that can be applied in the most diverse areas of industry, including food. New methods emerged and others were improved in order to achieve increasingly surprising results in terms of production and delivery.

At Liotécnica, this development was no different. Over the years, the company has evaluated and adapted to changes in consumption patterns. Today, we will highlight three processes that have been responsible for the manufacture of healthy, tasty and extremely high-quality products.

LYOPHILIZATION (FREEZE-DRYING)

Lyophilization, or freeze-drying, is a sublimation drying technique: the water present in certain foods’ changes from its solid state, to a gaseous state. For this to happen, the food is pre-frozen and placed in a vacuum chamber, where it remains until all its water sublimes.

With this, it is possible to preserve food in a better manner. Remembering that the freeze-drying process can be used on a wide variety of foods, such as fruits, greens and vegetables, meats and even coffees.

HOT AIR DEHYDRATION

It is a good alternative for drying certain types of food, where water – under controlled atmospheric conditions – is removed through evaporation. In this procedure, food (ground or in pieces) is placed on trays and exposed in such a way that hot, dry air circulates between it. Thus, the water present in the respective foods is evaporated.

VACUUM DEHYDRATION

This is a technology that consists of drying the product through a combination of heating and a vacuum. During the procedure, water is removed by evaporation, under vacuum, which promotes exposure of the food to milder temperatures.

This drying method is versatile and can be used with static or running equipment. Due to the length of time and because it works at milder temperatures, vacuum dehydration makes it possible to obtain products with very high quality and which more easily preserve their natural characteristics.

Constant innovations married with vast investments into different technologies, allows Liotécnica to not only be able to offer nutritious and high-quality products, but also to be a market leader in terms of agility, flexibility and variety.
