In the food industry, the extraction tank is widely used in the extraction and separation of food ingredients, and there are also some matters that need attention in the application.

In terms of application, the extraction tank can be used for oil extraction. For example, in the production of vegetable oil, oil can be extracted from oil crops through extraction tanks with suitable extractants.

In the mixing chamber, the extractant is fully mixed with the pulverized material of the oil crop, and the oil is transferred from the oil to the extractant phase, and then the extraction phase and raffinate phase containing oil are obtained in the clarifying chamber.

After subsequent treatment, such as distillation, the oil can be separated from the extractant to obtain pure vegetable oil. The extraction tank can also be used for extraction of food additives. Some natural food additives, such as flavors, colors, etc., can be extracted from plant raw materials through extraction tanks.

Select extractants with high selectivity for target food additives to achieve effective extraction in the extraction tank, providing natural and safe additives for the food industry. However, the use of extraction tanks in the food industry requires some considerations.

The first is the choice of extractant. Since food is directly related to human health, extractants must be non-toxic, harmless and meet food hygiene standards. Organic solvents that are harmful to the human body cannot be used as extractants, and natural, edible extractants or extractants that have undergone rigorous safety assessments should be preferred.

Secondly, to ensure the cleanliness of the equipment. The extraction tank needs to be strictly cleaned and disinfected before and after use to prevent microbial contamination and impurity residues. Maintain and maintain the equipment regularly to ensure the normal operation of the equipment and avoid food quality problems caused by equipment failure.

In addition, the operation parameters should be strictly controlled during the operation. Improper control of parameters such as temperature and extraction time may affect the quality and stability of food ingredients.

For example, excessive temperatures may cause the oxidation or breakdown of food additives, affecting their flavor and efficacy. The extraction tank has an important application in the food industry, but in the application process, attention should be paid to the selection of extractants, the cleanliness of equipment and the control of operating parameters to ensure the quality and safety of food.
