Problems solved by technology

Most of the traditional treatment methods are to spray or immerse the frozen aquatic products in the glazing solution. After the glazing is formed on the surface of the aquatic products, the glazing operation is completed. However, the above operation will cause the aquatic products to freeze. The thickness of the coating is uneven and the efficiency is low, and the quality of the ice coating cannot be guaranteed

Abstract

The invention discloses an ultrasonic-assisted ice glazing device and a control method thereof. The ultrasonic-assisted ice glazing device comprises a machine body, a placement plate, a liquid level alarm, an ultrasonic-assisted device, a drawing device and a control panel. The ultrasonic-assisted device consists of an ultrasonic flat plate, an ultrasonic vibrator and an ultrasonic generator; and the drawing device is composed of a drawing handle, an upper track and a lower track. According to the method, ice glazing is assisted by ultrasonic waves, the heat transfer effect is remarkably promoted, and the ice glazing time is shortened; crystal nucleus formation is promoted, the supercooling temperature required by crystal nucleus formation is reduced, the crystallization rate is increased, and ice crystals are formed more uniformly; and moreover, ice crystals are reduced, and the influence of the ice glaze on the aquatic products at the contact surface of the ice glaze and the aquatic products is reduced, so that the quality of the ice-glazed aquatic products is improved, and efficient and uniform ice glaze plating on the aquatic products is realized.

Description

technical field [0001] The invention relates to the fresh-keeping field of aquatic products, in particular to ice-coating equipment for aquatic products, and in particular to automatic ice-coating equipment for seawater fish. Background technique [0002] Aquatic products such as sea fish are high-quality protein sources for human consumption, and their meat is delicate and delicious. All kinds of aquatic products are deeply loved by consumers. In order to maintain the fresh and tender taste of aquatic products during frozen storage and avoid oxidation and dry consumption, aquatic products are often treated with ice coating. Most of the traditional treatment methods are to spray or immerse the frozen aquatic products in the glazing solution. After the glazing is formed on the surface of the aquatic products, the glazing operation is completed. However, the above operation will cause the aquatic products to freeze. The thickness of the coating is uneven and the efficiency is...
