Abstract

A control method for continuous pickling process of raw aggregate in gelatin production include steps of firstly, measuring ash content in the raw aggregate, calculating calcium content of the raw aggregate, and calculating theoretical acid consumption; secondly, measuring pH values at different inlets and outlets of continuous pickling tanks after starting pickling of the aggregate; thirdly, drawing curves of the measured pH values according to time synchronization; fourthly, calculating actual acid consumption by integral consumption according to graph and comparing the actual acid consumption to the theoretical acid consumption; and fifthly, calculating time for stabilizing stage of pickling, controlling pickling time accurately. The control method has the advantage that by means of real-time recording and real-time acid consumption integration, pickling degree can be judged, and pickling terminal point can be determined by comparison between the actual acid consumption and the theoretical acid consumption, the conventional manner of determining the pickling terminal point manually is replaced, error caused by human factor is reduced, the pickling process is more accurate and stable in control, and controllability and consistency of the pickling process are improved.

Description

technical field [0001] The invention relates to a gelatin production process, in particular to a control method for a continuous pickling process adopted in the pickling process of gelatin raw material bones. Background technique: [0002] There are many production processes of gelatin. The production of gelatin from aggregate needs to go through multiple processes such as sieving, pickling, liming, neutralization, washing, extraction, filtration, concentration and drying. Among them, the pickling process is through acid treatment (generally It is a certain concentration of hydrochloric acid) to remove the inorganic minerals in the aggregate, so as to facilitate further hydrolysis treatment in the post-process such as liming. The whole pickling process is the key to the gelatin production process, and its control will directly affect the production of gelatin. yield and quality indicators. [0003] The minerals in the aggregate are calcium phosphate (about 90%) and calcium ...
