Automatic control system for use in production process of caramel pigments

Abstract

The invention relates to an automatic control system for use in the production process of caramel pigments. A central control system is arranged in a central control room, and flow meters and regulating valves are arranged on an in-out pipeline of a material pre-fusion tank and are connected with the central control system; a temperature sensor, a pressure sensor and a steam regulating valve are mounted on a heating pipeline of an ejection heater and are connected with the central control system; pH detectors are arranged in the material pre-fusion tank, a laminar flow reaction tank, a flash tank, a coking burdening tank and a finished product tank; the central control system comprises a PLC controller and a terminal computer. According to the automatic control system, the whole production operation control is finished in the central control room, so that the manual operating errors are avoided, and the operation accidents caused by human factors are reduced as much as possible.

Description

technical field [0001] The patent of the invention relates to the field of producing caramel pigment, in particular to an automatic control system for the process of producing caramel pigment. Background technique [0002] Caramel pigment (Carame1), also known as caramel, is a colorant widely used in food, medicine and other industries. For the food industry, it is used in soy sauce, vinegar, cooking wine, sauce brine, pickled products, baking It is used in food, candy, medicine, carbonated beverages and non-carbonated beverages, etc. It not only imparts a specific color to the product, but also brings a specific caramel flavor. Caramel pigment is thick dark brown viscous substance, soluble in water, insoluble in organic solvents. In 1940, the U.S. Food and Drug Administration (FDA) issued regulations for caramel coloring. However, due to the toxicity of 4-methylimidazole contained in caramel coloring, its development is limited. After further in-depth research and experi...

AI Technical Summary

Problems solved by technology

The reaction takes a long time to heat up, the material is heated unevenly, and the holding time is long. The batch of products produced is single, and continuous production cannot be realized.

[0006] In terms of automatic control, due to the complicated process of producing caramel coloring, many reaction process experiments are still in the research stage, and the operation is not very mature, so the control of each step still relies on manual control
