Problems solved by technology
The traditional acid solution configuration completely relies on manual control to dilute 30% concentrated hydrochloric acid into 3%-4.5% dilute hydrochloric acid. Due to manual control, it is difficult to accurately configure the required concentration of dilute hydrochloric acid solution, which affects the quality of gelatin products, and the work efficiency is very low.

The invention relates to a process automatic control method, particularly relating to a hydrochloride solution dilution process automatic control method in the course of diluting concentrated hydrochloric acid used by osseous granula pickling in the production process of a gelatin into dilute hydrochloric acid. The hydrochloride solution dilution process automatic control method includes the following steps: 1) starting the system; 2) inputting the process parameter; 3) mixing; 4) stirringing with added air; 5) detecting; 6) outputting eligible dilute hydrochloric acid. The hydrochloride solution dilution process automatic control method is simple, the automation of the technological process is high, the operation is convenient, and the dilution precision of the solution is high. The method of the invention can realize the automatic control of hydrochloride solution dilution process.
Description
Technical field [0001] The invention relates to a process automatic control method, in particular to a hydrochloric acid solution dilution process automatic control method in the process of diluting concentrated hydrochloric acid used in the leaching of bone particles into dilute hydrochloric acid in a gelatin production process. Background technique [0002] The raw material for gelatin production is aggregate to make bone pellets. Pre-soaking and soaking are required. This step requires the use of a dilute hydrochloric acid solution with a concentration of 3%-4.5%. Therefore, the purchased 30% concentrated HCL solution must be diluted. The process equipment chooses concentrated acid storage tank, dilution buffer tank, concentrated acid pump, thin acid pump and other equipment, and the purified water is directly mixed with concentrated acid in the dilution buffer tank to achieve the purpose of dilution. The traditional acid solution configuration completely relies on manual cont...
