Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, in particular to quantitative packaging equipment and a process for high fructose corn syrup. Background Art

[0002] Fructose corn syrup is a product of mixed fruit juice and glucose syrup. It has the characteristics of high sweetness, good solubility and strong stability. It has been widely used in the food and beverage industry. It can be used in the production of a variety of foods such as beverages, cakes, bread, and candy. It can also be used as a sweetener for fruit juice to meet different taste and quality requirements. With the increasing demand of consumers for healthy food, the market demand for fructose corn syrup, as an ideal substitute for sucrose, continues to grow. The quality of fructose corn syrup directly affects the quality and taste of the final food. Quantitative packaging equipment can ensure accurate measurement of each filling without dripping, thereby ensuring the stability and consistency of the product.

[0003] The existing fructose syrup packaging equipment has the following defects: First, the positioning accuracy of the container during filling is significantly insufficient; the root cause of this problem is that the positioning system design of the equipment is not precise enough, resulting in the inability to accurately position the container during the filling process; the resulting filling deviation not only makes it difficult to maintain the same filling amount of fructose syrup, but also greatly increases the risk of leakage. The leaked fructose syrup will not only cause waste of raw materials, but also may cause pollution to the environment around the production line; second, there is a lack of a comprehensive inspection mechanism. In the existing packaging process, the control of the packaging weight of fructose syrup mainly relies on a single electronic metering pump for metering filling. This single control method is not only easily interfered by external factors (such as equipment wear, temperature changes, etc.), but also very easy to deviate in long-term operation, resulting in packaging weight not meeting the standard; third, when the equipment adopts high-pressure direct injection to fill fructose syrup, due to the large impact force, when the syrup quickly rises to the vicinity of the container bottle mouth, it often splashes under the strong impact, which not only pollutes the container mouth and the surrounding area, but also causes serious waste of raw materials; this splashing phenomenon not only increases the difficulty and cost of cleaning work. Summary of the invention
