Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for producing carbonated beverages containing fruit needles using a premix method, which can stably produce high quality carbonated beverages containing fruit needles by automatically controlling operation and maintenance.

Conventional fruit juice-containing carbonated drinks, commonly known as carbonated drinks, use only flavoring agents or blended syrup with a low fruit juice content, but even this production equipment has technical difficulties in terms of sterilization and operation and maintenance. It is long-lasting and requires a large amount of equipment.

In recent years, the preference for fruit juice drinks has increased, and carbonated drinks with fruit needles have been produced even in soft drinks.
As tastes change and product quality becomes higher quality, the amount of raw fruit juice used tends to increase.

However, since carbonated drinks containing natural fruit needles deteriorate due to microorganisms originating from the raw material natural fruit juice and secondary contamination during the manufacturing process, they must be thoroughly sterilized.

Furthermore, since the conventional premix method involves filling with gas and then sterilizing it, it is more difficult to produce carbonated beverages containing fruit juice, in which carbon dioxide gas is easily separated, than to produce beer.

The present inventor has made effective use of existing carbonated beverage production equipment, which allows for sufficient sterilization, easy operation, and maintenance, and also provides stable quality without impairing the taste, aroma, and color of fruit juice. The present invention was achieved as a result of various research into manufacturing methods and equipment that can easily produce carbonated drinks containing fruit needles.

The purpose of the present invention is to effectively utilize existing carbonated beverage production equipment, instant sterilize premixed fruit beverages at high temperatures before blowing carbon dioxide gas, and automatically process the manufacturing process of high-quality carbonated beverages containing fruit juice. To provide an apparatus for controlling and stably producing a carbonated beverage containing fruit needles.
