Food Cold Storage
Food Cold Storage
Cold storage is the primary method of low-temperature preservation of modern fruits and vegetables. Using vegetable storage can inhibit the activity of microorganisms and enzymes, and extend the long-term storage period of vegetables. Since the optimal range of vegetable fresh-keeping temperature is 0℃～15℃, fresh-keeping storage can reduce pathogenic bacteria The incidence of decay and the decay rate of fruits slow down the respiration and metabolism process of vegetables, achieving the purpose of preventing decay and extending the storage period.
The fresher the common vegetables, the better. When they are fresh, various nutrients, such as vitamins, are also the highest. Flowers, fruits, roots and leafy vegetables must be stored in the cold storage as soon as possible, and transported to the terminal market for wholesale using the cold chain transportation system retail.
Frozen fresh: refers to seafood that is quickly frozen at ultra-low temperature when it is most fresh and full, and then stored below -18°C. The advantage of frozen fresh is that the core temperature drops rapidly to -18℃ to achieve complete freezing, so that the water is completely solidified, preventing quality changes caused by fluidity, and ensuring the nutrition and quality of seafood. Frozen seafood can lock the nutrition and moisture in the seafood body, and keep the seafood to maximize its freshness during transportation. After thawing, it can restore the state when it was just caught. And can kill bacteria and prevent bacteria from invading, maintaining the original quality of the product, which is conducive to long-term storage.
This storage method is also widely used in seafood products suitable for raw eating. Due to the possibility of parasites such as Schistocephalus in sashimi, sashimi needs to be frozen at a low temperature to reduce the risk of infection. Under normal circumstances, the freezing period will increase by 3 times for every 10°C decrease in temperature. Fatty fish have a shorter frozen storage period for lower-fat fish, and red muscle fish have a shorter frozen storage period. The general freezing temperature is: the low-fat fish and aquatic products are between -18℃~-23℃; the fatty fish is below -29℃, and some red muscle fish may require a low temperature of -60℃. The lowest possible temperature should be used during freezing and transportation, and any temperature fluctuations should be avoided. The US FDA stipulates that fish must be frozen at -35°C for 15 hours, or frozen at -20°C for 7 days before being eaten raw, while the European Union requires freezing at -20°C for more than 1 day.
Dachang will promptly arrange professional technicians to make on-site measurements, combine the historical environmental factors of the actual location, and give customers the best suggestions and design solutions, so as to solve the customer's cold chain system needs in a one-stop manner.
The cold storage is divided into four types according to the temperature in the storage, low temperature storage, medium temperature storage, high temperature storage and ultra low temperature storage. The storage temperature of fruit preservation storage is generally 0~5℃, 2~8℃, 5~11℃, 7~12℃ , The cold storage with the most suitable storage temperature can be determined according to the customer's storage needs.
Cold storage Quotation
The storage body of a small fruit fresh-keeping cold storage is generally 15-20m², which can store 5-7 tons of fruit, and the investment is about 30,000 yuan. The main consumables of the cold storage include units, insulation boards, air ducts, refrigerants, wires and control boxes, etc., while the custom-made fruit fresh-keeping cold storage is generally about 1400~2000 yuan m².
After the two parties have agreed to make an appointment for the installation date and installation schedule in advance, the materials will enter the site at the specified time, and after the customer accepts the quality of all materials, the assembly can be implemented according to the predetermined plan.
