Juice and Tea Beverage Hot Filling Machine Process Introduction

In recent years, the development of fruit juices and tea drinks has been very rapid and it has almost doubled every year. In addition to beverage filling machine manufacturers have launched hot filling projects, other industries are also scrambling and hope to get a piece of cake. As a result, the manufacturers who made the equipment emerged more than a dozen nights regardless of the conditions. Although the appearance is good and the price is very low, some of the technical details are not satisfactory.

Through the widespread use of users, it is considered that in addition to the above basic functional requirements, hot-filling equipment has multi-faceted capabilities and experience that are critical to the stability of the filling valve. Select high-quality stainless steel, should fully consider its different functions and working conditions, according to the material category, chemical composition, mechanical properties, reasonable selection, and then through the necessary process, CNC machining, to ensure optimal tolerance, quality control Point to check, in order to meet the long-term high temperature state, the performance of the filling valve for a long-term stable filling valve leakage problem. The key is the selection of the inner seal of the filling valve and the guiding member. The influence of the thermal deformation of this type of material at high temperature should be considered. When designing and manufacturing juice filling machines, hardness and fitting size should have empirical data, and select the appropriate one. 

Juice and tea beverage usually adopt high-temperature hot filling and cold aseptic filling. Due to many conditions, domestic companies generally adopt the former. The process of making juice and tea beverages is strict. From the comprehensive comparison of the processing technology of PET bottle filling, the operation of the production line and the quality of drinks, it is economical and reliable to select the hot filling process. Hot filling requires that juice and tea beverages be kept at a constant value between 85℃and 95℃ after UHT transient ultra-high temperature sterilization, and the filling in a short time, which is a high temperature filling.

Generally, carbonated drink filling machines are mostly positioned or quantitative, and the material always has a certain distance from the mouth of the bottle. Juices, tea drinks, especially those produce original flavors, require the material to be filled at the mouth, that is, the bottle is filled all the way to the mouth, so that there is very little residual air in the bottle, which ensures that the beverage itself is not easily oxidized, so that the beverage can be long-term maintain its quality. Since hot filling requires high-temperature filling and full-mouth filling, it requires an automatic circulation system to facilitate low-temperature material circulation heating and CIP cycle cleaning. Hot filling should have the following functions: filling and conveying by bottle neck, full mouth filling, backflow control function, automatic circulation function.
