Description
Technical Field
The invention belongs to the technical field of fresh ice refrigeration, and particularly relates to a refrigeration appliance with a fresh ice chamber.
Background
The well-known common preservation method of seafood aquatic products is as follows:
1. freezing: in order to meet the requirements of long-term preservation and long-distance transportation of marine products, people are used to freeze the marine products in a refrigerator or a freezer, which is what we often say as frozen seafood. Freezing is storage at a temperature below-18 deg.C, and when the temperature of the marine product is reduced from normal temperature to below 0 deg.C, water in the marine product will coagulate to generate ice crystals, thereby destroying its muscle and tissue structure.
Before cooking, thawing is needed, and the cell part is damaged in the thawing process, and the water and juice in the cell part can be separated out, so that the nutritional ingredients and the flavor of the seafood can be influenced to a certain extent, and the taste of the seafood is inferior to that of fresh seafood. However, seafood can be stored in large quantities and transported over long distances by freezing, so that there is a competitive advantage in terms of price.
2. Freezing and refreshing: the fresh seafood is collected, and the temperature of the seafood is reduced to about 0 ℃ in a short time by using crushed ice layering, and the temperature range is kept in the transportation and storage processes.
The main advantages of ice freshness: the seafood is kept at about 0 ℃, the meat quality is kept soft, the propagation of bacteria can be prevented at low temperature, the taste and the nutrition of the seafood can be well kept, and the seafood is more delicious than frozen seafood. Meanwhile, the fresh-keeping period of the frozen seafood is short, the frozen seafood is required to be transported to a destination from a production place as fast as possible, and a place far away from the production place even needs to be transported by air, so that the logistics cost is high, and the price is high. Seafood with high economic value and good meat quality: such as shrimp, large yellow croaker, sea bream, grouper, etc. are preserved by the method.
The main drawback of icy foods: seafood has short preservation time, and the seafood is extremely easy to deteriorate after ice melts, so the seafood is not suitable for long-term preservation.
3. Soaking in ice water: the method for soaking the ice water is also a common method for preserving seafood, the seafood is kept fresh by soaking the ice water in order to prevent the seafood from going to the market from a fishing boat.
The advantages of soaking in ice water are: can cool the seafood quickly and keep the quality and taste of the seafood.
Disadvantages of ice water immersion: if the time for soaking the ice water is too long, the ice water can permeate into the seafood due to the large salt content in the seafood, so that the cell structure of the seafood is damaged, and the taste of the seafood is damaged. For example, the weight of octopus can be increased by more than 3 percent by soaking the octopus in ice water.
4. Quick-freezing: the quick-freezing technology is a preservation technology developed in recent years, the temperature of the seafood is sharply reduced by a special low-temperature method, and the muscle structure of the seafood is not damaged and the quality and the taste of the seafood are kept to the maximum extent due to the fact that the temperature of the seafood is reduced by blocks and the moisture in the seafood cells is not frozen in time, so that the method is the best preservation method at present.
The quick freezing can make the seafood cells enter a 'dormant' state without being damaged and keep the activity again after being 'unfrozen'.
Freezing error zone: many households are accustomed to placing seafood in a refrigerator for frozen storage, which is thought to ensure that they do not spoil. In fact, the seafood is stored in the refrigerator for too long time, which causes fatty acid bands and changes in fat properties, and after the seafood is eaten by people, vitamin B2 in the human body is easily lost, and the resistance is reduced.
Freezing does not kill the bacteria, and it is obviously impossible to "freeze" the bacteria in a refrigerator. Cryopreservation can cause bacteria to enter a "dormant" state and not to reproduce. After thawing, however, only a few hours at normal temperature, the number of bacteria is doubled. If the seafood is thawed and then frozen again, the seafood is not suitable for eating because the number of bacteria is obviously increased. That is, the food which is frozen twice is most suitable for the appetite of bacteria.
From the above points, we can conclude that the optimal storage mode of the seafood aquatic products is quick freezing and placing the seafood aquatic products on solid ice. The temperature of the seafood is guaranteed to be about 0 ℃ and the environment with high humidity is most beneficial to the long-term preservation of the seafood. However, the characteristics of the air-cooled frostless refrigerator determine that the generation and maintenance of ice in the room cannot be realized.
At present, the development trend of the refrigerator industry is developed from the traditional energy conservation to the directions of fine zoning, fresh keeping, silence and the like, and the traditional 'freezing and fresh' concept of the refrigerator is that the temperature is simply maintained at about 0 ℃ and the humidity is not controlled; the water of the seafood aquatic product is easy to lose; the seafood and the seafood are not specially partitioned, and if the seafood and the seafood are not properly stored, the fishy smell is easy to pollute other foods and cause the taint of smell.
