High-voltage alternating-electric-field marine product preservation device

Abstract

The invention discloses a high-voltage alternating-electric-field marine product preservation device. A process-control broadband multi-waveshape signal generator in the preservation device outputs alternating current signals with different frequencies and waveshapes; a high-frequency transformation-ratio-adjustable transformer performs alternating current signal voltage boosting and then outputs high-voltage alternating current; the high-voltage alternating current is output to an electric field generating device through a high-voltage-resistant insulation wire; one end of the high-voltage-resistant insulation wire is connected with a safety resistor in series and then is connected with an electrode plate of the electric field generating device, and in addition, the other end of the high-voltage insulation wire is directly connected with another electrode plate of the electric field generating device. Electric field superposition is performed on marine products by use of the electric field generating device, so that cells of the marine products generate micro-vibration, so that the marine products are preserved without being frozen in a partial freezing environment with a temperature range of -3 DEG C to -5 DEG C.

Description

technical field [0001] The invention relates to a high-voltage alternating electric field aquatic product preservation device. Background technique [0002] At present, the preservation of aquatic products mainly adopts the method of low-temperature refrigeration and freezing. Generally, three temperature zones are selected: 0-4℃ refrigeration, -1-4℃ freezing and -18-40℃ freezing storage. Usually, high-temperature cold storage has a very short preservation period, which can only last for a few days. Long-term freezing will lead to unpredictable protein denaturation, water-holding capacity reduction, and juice loss after thawing. Big discount. [0003] At the same time, fishing boats that use traditional freezing and fresh-keeping often carry crushed ice when they go out to sea, and the fish is mixed with crushed ice when they enter the warehouse, resulting in inevitable mechanical damage to the fish body and uncontrollable microbial infection; the center temperature of the ...

[0003] At the same time, fishing boats that use traditional freezing and fresh-keeping often carry crushed ice when they go out to sea, and the fish is mixed with crushed ice when they enter the warehouse, resulting in inevitable mechanical damage to the fish body and uncontrollable microbial infection; the center temperature of the catch is generally high At 0°C, various endogenous deteriorating enzymes in the muscle cannot be effectively inhibited, and exogenous microorganisms left on board due to improper preservation interact with each other, resulting in a sharp decline in the quality and freshness of aquatic products at the source of fishing
