What kinds of commonly used foods can be stored in cold storage?

Look at the size of your cold storage and the temperature, these two parameters determine your cold storage, build cold storage regardless of rural or urban, as long as you need to build, 30 cubic meters of cold storage cost in about 10,000, at present, do more is popsicles, seafood, quick-frozen, frozen meat, dairy products, vegetables, fruits, tea, medicine, hot pot base and so on, this should be set with your local sales situation, do not be too blind, after all, entrepreneurial funds are very valuable.

Yes, the prospects are good, and I am ready to build it!

It depends on how big the cold storage you build. There are more things to put. Insurance. Quick-frozen. There are zeros. It is about minus 18 degrees. It is about minus 28 degrees.

Cold storage (coldstorage) is the abbreviation of cold storage, mainly for food, dairy products, meat, aquatic products, poultry, fruits and vegetables, cold drinks, flowers, green plants, tea, medicines, chemical raw materials, electronic instruments and instruments to play a constant temperature storage effect. According to different classification methods, cold storage is roughly divided into the following types:

1. According to the scale of cold storage capacity, it is generally divided into large, medium and small

The refrigeration capacity of large-scale cold storage is more than 10,000t;

The refrigeration capacity of medium-sized cold storage is 1000-10000t;

The refrigeration capacity of small cold storage is less than 1000t.

2. According to the design temperature of refrigeration, it is divided into four categories of cold storage: fresh-keeping, low-temperature, quick-frozen and ultra-low temperature

Fresh-keeping cold storage is generally used for fresh food, such as fruits and vegetables, meat and eggs, dairy products, etc., and the temperature is controlled at 0-5;

The refrigeration temperature of low-temperature cold storage is between -25--18, and some foods that need to be frozen can be used in low-temperature cold storage;

The temperature of quick-frozen cold storage is lower, about -30 below, many quick-frozen foods, quick-frozen vegetables and fruits and other foods that need to be frozen quickly, you can use quick-frozen cold storage;

The cold storage with a refrigeration temperature of -45-60 is called ultra-low temperature cold storage, which is generally used for the storage of industrial products, such as some medicines, vaccines, and some seafood and fish.

3. According to the purpose of cold storage, it can be divided into food cold storage, pharmaceutical cold storage and chemical cold storage

Food cold storage is mainly used to store food, keep it fresh and safe;

Pharmaceutical cold storage is used to store drugs and vaccines, maintaining their effectiveness and safety;

Chemical cold storage is used to store chemicals and raw materials, maintaining their stability and safety.

4. According to the refrigeration mode of cold storage, it can be divided into compressor refrigeration cold storage and absorption refrigeration cold storage

The compressor refrigeration cold storage compresses the refrigerant into high-temperature and high-pressure gas through the compressor, and then releases the heat through the condenser heat dissipation, so that the refrigerant becomes a high-pressure liquid, and the refrigeration effect is cooled and evaporated through the expansion valve, so as to achieve the refrigeration effect;

Absorption refrigeration cold storage uses absorbent to absorb and release refrigerant, so as to achieve refrigeration effect.

According to the storage temperature, it can be divided into these types:

1. High-temperature small cold storage: mainly used to store fruits and vegetables, eggs, medicinal materials, wood preservation, drying, etc. The temperature is usually at 0 15 to the air cooler.

Blow cooling.

2. Medium temperature small cold storage: mainly used to store meat, aquatic products, poultry meat, etc., generally the storage temperature is -15 -18.

3. Low-temperature small cold storage: also known as freezing storage, freezing cold storage, freezing of food through air coolers or special freezing devices, the temperature is -18 -25. It is mainly used for quick-frozen food, industrial testing, medical and other special purposes.

4. Quick-frozen small cold storage: quick-frozen cold storage, used for rapid freezing of food.

In order to solve the cold chain monitoring needs of cold storage at different temperatures, for example, to help pharmaceutical and vaccine companies monitor the real-time monitoring of temperature and humidity of drug reagents in cold storage, Jingchuang cold cloud monitoring and monitoring cloud platform can be used.

The platform is FSP compliant, grabbing offline data from devices for backup analysis; Data missing alarm notification, prevent offline data loss, sound and light alarm prompt + manual background supervision. There are also refrigeration industry engineers, who can remotely set parameters and remotely switch on and off functions, aiming at the misoperation of employees of chain restaurants or fresh cold chain enterprises, resulting in food deterioration or food safety.

accidents, hierarchical alarm mechanism + manual background monitoring, adapt to the comprehensive monitoring scheme of food production enterprises, import and export **, and cold storage in logistics centers to ensure food safety.

Cold storage can be classified according to its purpose of use and the scale of construction.

1.According to the purpose of use, cold storage can be divided into productive cold storage, distribution cold storage and retail cold storage.

Productive cold storage mainly exists in the field of production and processing of food origins, and is used for refrigerated processing, storage and transportation of food.

Distributed cold storage is mainly used for the storage and transportation of food, as well as as as the best channel for the food retail and catering industry.

Retail cold storage is typically located in retail outlets such as supermarkets and convenience stores to store and display food and other products that need to be refrigerated.

2.According to the scale of the building, cold storage can be divided into large cold storage and small cold storage.

Large cold stores are typically used for industrial and commercial purposes, with large storage space and advanced refrigeration equipment to store large quantities of food and other products.

Small cold storages are often used in homes or small commercial establishments, with smaller storage space and simple refrigeration equipment to store small quantities of food and other products.

In addition, according to the temperature control range, cold storage can also be divided into high temperature cold storage, low temperature cold storage and ultra-low temperature cold storage.

The temperature of high-temperature cold storage is usually between 0 and -10 and is mainly used to store food that needs to be refrigerated but still needs to be kept at a certain temperature.

The temperature of low-temperature freezers is usually between -18 and -25 and is mainly used to store food and other products that need to be frozen.

Ultra-low temperature freezers are usually between -30 and -80 and are mainly used to store food and other products that require special ultra-low temperature storage, such as tuna.

In general, different types of cold storage have different purposes of use, building scale and temperature control range, which can be selected and used according to actual needs.

Cold storage is a storage building that uses artificial refrigeration to cool down and has the function of cold insulation, including warehouse, refrigeration machine room, substation and distribution room, etc.

The types of storage include food, medicine, blood, and vaccines.

According to the structural form, it is divided into civil cold storage and prefabricated cold storage.

Hope, thank you!

1. Air natural convection straight coarse lead freezing method.

That is, a wall pipe or a top pipe is set up in the freezing room of Dingzhou cold storage, and the natural convection of air is used to freeze the food. In order to improve the heat transfer coefficient of the manifold pipe. Axial fans can be installed in the cold storage.

In order to appropriately speed up the movement speed of the air in the warehouse. When the cold storage temperature is -23. The freezing time generally takes 48-72h.

This method of freezing takes a long time. At present, it is only used in small cold storage freezers.

2. Direct freezing method of forced air convection.

That is, a floor-mounted or ceiling-mounted air cooler is installed in the freezer room of the cold storage. Accelerate the flow of air in the cold storage and enhance the efficiency of heat exchange. When the cold storage temperature is -23, the freezing time of food is about 16-20h, and its freezing speed is fast, which is widely used for the current large and medium-sized cold storage stool.

3. Semi-contact freezing method.

Install the shelving pipes in the freezer room. Fish and poultry are packed in iron trays and placed on shelves and pipes to freeze. It can also be equipped with an axial fan to speed up the flow of air.

Since the food is in direct contact with the pipe through the iron plate for heat exchange, the freezing speed is accelerated compared with the direct freezing method of natural air convection. When the temperature of the cold storage is -23, the freezing time is about 30-40h. This method is mostly used in small cold storage freezers.

4. Dingzhou cold storage quick-freezing method.

Quick-freeze food. Not only can the freezing time be shortened. It can also effectively improve the quality of freezing. It is suitable not only for freezing meat products, but also for fruits, vegetables and pasta, and has good freshness and a long storage period.

In addition to the well-known variety of meats and fish, and ice cream, which can only be stored at sub-zero temperatures, there are unexpected advantages to putting these foods in the freezer.

1.Tea.

It is easy to lose the aroma after a long time, so it can be divided into small packets, tightly wrapped in impermeable packaging, and then put into the freezer. In this way, the next year you take it out and drink it, and the taste is still as fresh as ever.

2.Starch-rich foods such as bread.

All kinds of cooked staple foods will dry out and harden over time. Whether it's rice, steamed buns, noodles, cakes, it's the same.

3.Legumes and dried fruits.

Legumes, nuts, dried fruits, etc. are all susceptible to insects. In particular, delicious raisins and dates often grow some nasty meat bugs. If they are divided into small packets that can be eaten in advance, wrapped tightly and then placed in the freezer for two or three weeks, the eggs naturally carried in natural foods will not hatch normally, and the sealed agricultural products can be stored for a longer time.

The freezer compartment should also be stratified.

1.Lower.

Raw foods that need to be heated sufficiently: raw fish, raw meat, seafood, raw tofu, these can be placed on the lower layer.

2.Superstratum.

A variety of cooked pasta, pastries, and other starchy staples, as well as a variety of cold drinks, are placed on the upper level.

3.Other.

All kinds of homemade quick-frozen foods, such as home-made frozen buns and frozen dumplings, homemade quick-frozen peas, quick-frozen toons, quick-frozen beans, quick-frozen strawberries and mulberries, etc., are placed in the middle layer or placed on the upper layer together with the quick-frozen staple food. In any case, it must be separated from fish and seafood.

The following vegetables and fruits can be stored in the thermostatic cold storage according to the temperature conditions:

About 0: Most of the rhizomes and leafy vegetables are cool fruits and vegetables (native to the temperate and cold zones), and the suitable storage temperature is 0-2 and cannot be lower than 0. Cabbage, spinach, cauliflower, celery, carrots, peaches, grapes, apples.

When these fruits and vegetables are just purchased, it is best not to put them in cold storage immediately, because the low temperature will inhibit the enzyme activity of fruits and vegetables, so that the residual toxins cannot be decomposed. Therefore, it is best to store these fruits and vegetables at room temperature for a day before putting them in cold storage.

About 10: tomatoes, cucumbers, persimmon peppers, lychees, bitter gourds, cowpeas, pumpkin lantern vegetables, suitable storage temperature is generally about 10; Due to the high water content, these fruits and vegetables will turn black, soft and taste after being refrigerated for a long time.

10 or more: Tropical fruits are best kept in a dark, cool place. If you must put it in cold storage, it should be placed in cold storage with a high temperature, and it is best not to store it for more than two days.

The suitable storage temperature of bananas, lemons, pumpkin lantern fruits and vegetables is 13-15, and low temperature storage is easy to make them black and rotten.

This Cold Storage Design Code can answer your questions.

The above is a common classification of cold storage types, and the size and nature of the cold storage should be determined before the construction and installation of the cold storage, so as to make the budget accurate.

Cold storage is a kind of warehouse for storing fruit or dust, such as the storage of fruit is a kind of warehouse for seafood and meat, such as the fruit is stored at a low temperature of about 0 degrees to 4 degrees, but not freezing, if it is to store seafood or meat, this is an ultra-low temperature below minus 30 degrees, so that the storage of meat is not easy to deteriorate.

Generally, the cold storage is mostly cooled by the refrigeration machine, and the liquid (ammonia or freon) with a very low gasification temperature is used as the coolant, so that it can evaporate and absorb the heat in the storage warehouse under the conditions of low pressure and mechanical control, so as to achieve the purpose of cooling and cooling. The most commonly used is the compression refrigerator, which is mainly composed of a bonding machine in the pressing, a condenser and an evaporation tube. According to the way of evaporation pipe device, it can be divided into two types: direct cooling and indirect cooling.

Direct coolingThe evaporation tube is installed in the refrigerated warehouse, and when the liquid coolant passes through the low-pressure evaporation tube, it directly absorbs the heat in the warehouse and cools down. Indirect suffocation cooling is by the blower to suck the air in the warehouse into the air cooling device, and the air is absorbed by the evaporation pipe hovering in the cooling device, and then sent to the warehouse to cool down. The advantage of the air cooling method is that the cooling is rapid, the temperature in the warehouse is more uniform, and at the same time, the harmful gases such as carbon dioxide generated during storage can be taken out of the warehouse.

In terms of environmental monitoring and diagnosis of cold storage, professional equipment is needed, and Jingchuang Cold Cloud is currently doing a good job. It is a monitoring and monitoring cloud platform based on Jingchuang terminal equipment for the cold chain industry. Through Internet of Things technology, cloud computing, big data analysis, intelligent temperature control and other technologies, based on the cold chain safety monitoring industry, we will build a global cold chain security cloud service sharing platform to monitor, diagnose, warn and control the whole cold chain environment of food and drug production, storage, transportation and sales.
