Embodiment 1

[0041] Embodiment 1 air conditioning thawing device of the present invention

[0042] The controlled atmosphere thawing device of the present invention includes a box body for placing the object to be thawed which can form a closed space, a power supply unit, a temperature control unit, a gas mixing unit, an air extraction unit, a sterilizing unit, and an alarm unit. unit and a system control unit, the system control unit is used to control the work of the power supply unit, temperature control unit, gas mixing unit, air extraction unit, sterilization unit and alarm unit, so as to form a thawing working environment in the box.

[0043] The box body is composed of a box body door and a box body body. The box body door can be opened and closed freely. In the closed state, it forms a closed space with the box body body; the closed space can be closed within 12 hours. , the internal and external gas exchange rate is less than 2%; the box is provided with a built-in shelf for placi...

Embodiment 2

[0055] Embodiment 2 thawing bigeye tuna with controlled atmosphere thawing device

[0056] The steps and results of thawing bigeye tuna using a controlled atmosphere thawing device are as follows:

[0057] (1) Turn on the power supply of the controlled atmosphere thawing device and the gas source switch of the gas mixing instrument;

[0058] (2) Set the ozone sterilization time to 20 minutes on the control panel of the minimum system unit of the single-chip microcomputer. After closing the door of the sealed box, click the confirmation button to start operation, and the ozone generator will generate ozone to sterilize the inside of the sealed box;

[0059] (3) After the ozone sterilization is completed, put the raw tuna pieces on the shelf in the sealed box, close the door of the box, set the thawing temperature to 4°C on the control panel of the smallest system unit of the single-chip microcomputer, and set the gas CO 2 :O 2 The ratio is 3:2, the set vacuum degree is 490Pa ...

Abstract

The present invention provides a modified atmosphere thawing device for omophagia seawater fish and a thawing method thereof. The modified atmosphere thawing device comprises a box body, a power supply unit, a temperature control unit, a gas mixing unit, an air pumping unit, a sterilizing unit, an alarm unit and a system control unit. The method comprises the following steps: (1) setting ozone sterilization time in the system control unit, closing a box body door, and operating the ozone sterilization process; (2) placing the well-cut seawater fish flesh on a shelf after finishing the ozone sterilization process, closing the box body door, setting thawing procedure parameters including thawing temperature, thawing time and types and proportions of mixed gas in the system control unit, starting the thawing procedure, and stopping the thawing procedure until the thawing procedure runs over. The modified atmosphere thawing device and the thawing method have effects in improving redness value and durability of the omophagia seawater fish products, reducing product thawing loss, inhibiting microbial growth and reproduction, etc., and can make the products relatively ruddy and attractive in color, improve product quality and safety levels, prolong shelf life and increase product revenue.

Description

technical field [0001] The invention relates to the thawing technology of aquatic products, in particular to an atmosphere-controlled thawing device and a thawing method for seawater fish eaten raw. Background technique [0002] Tuna is also called tuna and tuna. The fatty acids in the meat are mostly unsaturated fatty acids, which are rich in DHA and EPA. Minerals and trace elements, with high protein, low fat and other characteristics. Tuna raw food products are of high quality, with the characteristics of round taste, smooth but not greasy, pure and natural color, and elastic meat. It is known as a rare nutritious delicacy for modern people. [0003] Tuna generally needs to go through a long period of storage and storage from catching to eating. In order to maintain the excellent nutritional and sensory characteristics of tuna, tuna will be quickly frozen after harvesting and stored at -55°C or even lower. The process of melting the ice crystals inside a frozen food pri...
