Electrostatic aquatic product flour coating device and method thereof

Abstract

The invention discloses an electrostatic aquatic product flour coating device and a method thereof. The electrostatic aquatic product flour coating device comprises an air jetting system, a flour supply device and an electrostatic generation device. The electrostatic aquatic product flour coating device adopts an air jetting technology which is combined with the flour supply device to spray flour, a high-voltage electrostatic field is built between a sprayer and an aquatic product which is grounded simultaneously, and the flour has charges in a corona discharge manner; under the combined action of airflow acting force, electric field force and gravity, all flour particles with or without charges in air flow move towards the aquatic product, and as the charges of the flour particles are the same in character and have repulsive interaction, the flour particles can disperse from one another uniformly in the movement process and thus form a uniform flour coating layer on the surface of the aquatic product. The electrostatic aquatic product flour coating device has the characteristics of simple structure, convenience in operation, uniformity, high efficiency and saving of flour, and serves as a new technical device for coating aquatic products with flour.

Description

technical field [0001] The invention relates to the field of food machinery, in particular to an electrostatic powder coating device for aquatic products and a method thereof. Background technique [0002] During the processing of aquatic products, the surface of aquatic products is sometimes covered with a layer of powder according to needs. The powder used is usually a pre-mixed powder. It is mainly made of flour or starch, and thickeners, seasonings, coloring Its main function is to increase the taste and color of the product, as well as increase the added value of the product. At present, in aquatic product processing enterprises, the powder coating operation is completely carried out manually. The main disadvantages of the manual powder coating method are that the powder coating speed is slow, uneven, leaking, and the powder material is used for a long time. After a long time of operation, the powder humidity in the tray increases, resulting in the powder layer on the ...

AI Technical Summary

Problems solved by technology

The main disadvantages of the manual powder coating method are that the powder coating speed is slow, uneven, leaking, and the powder material is used for a long time. After a long time of operation, the powder humidity in the tray increases, resulting in the powder layer on the surface of the aquatic product in the oil. Shelling occurs during frying, which affects product quality and sales. Another problem is that food safety problems exist due to manual operation.
