Description

Low TEMPERATURE AND HIGH SPEED EVAPORATOR

The present invention relates to a concentrator, and more particularly, to a low-temperature high-speed concentrator for drying a concentrate more quickly and effectively for the production of powdered food and the like, and for producing a powder.

A spray dryer or concentrator is a device that disperses a liquid material into fine particles in a high-temperature airflow to significantly increase the specific surface, and dries or concentrates it in a relatively short time, such as milk powder, coffee, glucose, etc. It is used for the manufacture of powdered food, etc., or the treatment of by-products such as waste liquid.

Various technologies have been developed for such a spray dryer. For example, Korean Patent Registration No. 10-1690065 discloses a concentration system through evaporation, and discloses a structure of an evaporator extending in the vertical direction.

In addition, Korean Patent Registration No. 10-1241126 discloses a technique for performing compression or concentration using mechanical vapor recompression vapor.

As such, in the case of a conventional spray dryer or concentrator, a system for compressing or concentrating for a predetermined time by providing high-temperature steam into a predetermined chamber in which the concentrate is located has been generally used.
