Description

Technical Field

[0001] This invention relates to the field of fruit juice preparation, and in particular to a novel device and control method for quantitative preparation of various fruit juices. Background Technology

[0002] In the industrial production of beverages, multiple processes involve fruit juice blending, which generally involves mixing water and fruit juice ingredients in a predetermined ratio and ensuring thorough homogenization and dissolution. Existing fruit juice blending equipment suffers from insufficient precision in proportion control and limited single-batch blending capacity. Poor material uniformity directly impacts the taste of the finished fruit juice. Currently, fruit juice blending is mostly conducted online on production lines, which is prone to deviations in proportion accuracy. Direct mass production without prior pilot-scale blending can easily lead to raw material waste. Furthermore, laboratory-scale fruit juice blending largely relies on manual calculations and manual ingredient addition, making it difficult to guarantee blending accuracy and resulting in low work efficiency.

[0003] In the field of NFC (Not From Concentrate) juice production, NFC juice retains the original characteristics of fresh fruit to the greatest extent. Compared to concentrated reconstituted juice, its flavor, taste, and nutritional value are closer to fresh fruit, and it typically contains pulp components with prominent flavor characteristics. Due to differences in raw fruit varieties, ripeness, and growing light conditions, the physicochemical properties of NFC juice prepared from different batches of raw materials fluctuate. Therefore, controlling key physicochemical parameters such as sugar content, acidity, and pH value to stabilize the product's taste is a crucial step in NFC juice production. Currently, NFC juice blending still predominantly relies on manual blending methods, which suffers from drawbacks such as cumbersome operation, time-consuming and labor-intensive processes, and low production efficiency.

[0004] Based on the above situation, the industry urgently needs a device that can be applied to laboratory settings and achieve high-precision automated quantitative mixing of multiple types of fruit juice. Summary of the Invention

This invention integrates multi-dimensional information acquisition technology using pH sensors and miniature multi-dimensional sensors to collect juice parameters in real time and feed them back to the juice blending control system. It can accurately detect individual indicators of various juices while simultaneously achieving precise quantitative blending of mixed juices, effectively improving the efficiency of juice blending operations and eliminating the tedious process of manual proportion calculation.

It can automatically adjust the juice feeding ratio and conveying flow rate of each feeding channel according to the user's preset target parameters such as the pH value of the finished juice and the online sugar content. At the same time, it integrates a one-button cleaning function to realize the automated cleaning of the equipment pipeline.
