Food additives are synthetic or natural substances added to food to improve the color, aroma and taste quality of food, as well as for preservation and processing needs. At present, there are 23 categories and more than 2,000 varieties of food additives in my country, including acidity regulators, preservatives, defoaming agents, antioxidants, bleaching agents, bulking agents, colorants, color protectants, enzyme preparations, flavoring agents, and nutritional agents. wait. Enhancers, preservatives, sweeteners, thickeners, aromatics, etc.

Production method of citric acid
The production methods of citric acid can be divided into three types: fruit extraction method, chemical synthesis method, and biological fermentation method.
Production Process
Using dried potatoes as raw materials, direct crushing, pulping, and liquefaction are used to carry out aerobic liquid deep fermentation, calcium salt method extraction, evaporation, concentration, and then crystallization; after crystallization, a centrifuge is used for solid-liquid separation, and the resulting wet lemon is The acid crystals are dried and screened to obtain the finished product citric acid.
Improver classification
Steamed bread flour quality improver, noodle flour quality improver, flour gluten enhancer, dried noodles anti-odor improver, glutinous rice ball flour quality improver, quick-frozen dumpling quality improver, bread flour quality improver, etc.
Production Process
Raw materials [formulation] - dust-free feeding station/ton bag feeding station - vibrating screen - mixer - vibrating screen - packaging - palletizing
It adopts advanced sealing technology to prevent leakage and extend service life. The sealing gap can be automatically compensated with the use process.
The in-line screen uses a high-frequency vibration motor as the excitation source. After the material enters the system, it undergoes a three-dimensional rotational movement on the screen surface due to the force of the vibration source. The flour and agglomerates are fully dispersed, and quickly pass through the screen and directly enter the lower noodle bin. Impurities and foreign matter are separated and discharged to the slag discharge port, playing the role of “quality assurance officer” on the production line.
The in-line screen can be used in the feeding system at the front end of production lines such as instant noodles, dried noodles, snacks, solid beverages, etc. to separate foreign matter in raw materials (flour, starch, milk powder, additives, etc.). Because it is connected in series in the system and automatically separates foreign matter, it is known as the “quality assurance officer” of the food production line. The flour sifter can replace the manual observation of finding foreign matter and sorting it.
