How much does it cost to build a cold storage

The cold chain has been naturally pushed to the forefront of the storm and has become a hot topic in the food logistics industry. The construction of a cold chain system is of great significance. The food cold chain refers to the fact that after perishable food is purchased or fished from the place of origin, it is processed, stored, transported, distributed and retailed until the hands of consumers, and its various links are always in the required low temperature environment. To ensure food quality and safety, reduce losses...

How much does it cost to build a cold storage?

　　 One, cold storage price

　　The price of a cold storage is the first factor that everyone considers before building a cold storage. How much does it cost to build a cold storage, what materials are needed, and what about the later operating costs after the cold storage is built? Is the power consumption of cold storage high? How long can the cold storage be used? Can I apply for national agricultural machinery subsidies when building cold storage? These are all factors that must be taken into account in the price of cold storage. If you make reasonable use of these factors, you can effectively reduce your own cold storage cost and build the best cold storage at the most affordable cold storage price!

　　 2. Four factors that must be considered in the price of cold storage

With people's continuous understanding of cold storage, the wide range of applications of cold storage (can be used in the food industry, pharmaceutical industry, chemical industry, hotel and catering, electronics industry, etc.), people's demand for cold storage continues to increase, but many people The knowledge of cold storage is not well understood. Many customers only ask about the price of cold storage. Then several cold storage companies compare the prices. Whoever has the cheaper price will choose his product. In fact, this is a very wrong view. There are many factors to be considered in the cost. If only considering the price, it may affect the quality and after-sales service of the cold storage

　　 1. The size of the cold storage

Generally speaking, the larger the cold storage, the higher the requirements for technology and materials. The price of a large cold storage is definitely not calculated according to the size of a small cold storage one to two times, but a doubled increase, and the larger the cold storage, The better the preliminary work is, because the maintenance of a small problem in a large cold storage may involve many aspects of the problem. Sometimes if some large equipment needs to be modified, it is equivalent to the price of a small cold storage, so the preliminary work and after-sales of the cold storage Service is something that must not be ignored.

　　 2. Cold storage unit

There are many brands of cold storage units, and the prices of various brands are also different. The price of a brand with good quality is relatively higher. I know that many customers now choose things based on the reputation of a company’s brand reputation. Therefore, when choosing a unit, we generally suggest that you choose a brand with a better quality. Although the cost may be higher than that of an ordinary unit, these things will bring unexpected effects to me in the later stage.

　　 3. The problem of cold storage temperature

　　Different temperatures require different configurations. There are three types of cold storage: high, medium, and low. Generally speaking, the lower the temperature of the cold storage of the same area and height, the higher the price. The temperature of the cold storage has a great relationship with the quality of the cold storage board, and the prices of various materials will also vary.

　　 4. Logistics cost issues

The price of buying a cold storage locally is completely different from the price of buying a cold storage in the Mainland. If you find a cold storage in the local area, you can save a lot of expenses and the construction is convenient. If you find a foreign company to build it, this You need to increase some material transportation and processing fees, labor costs, etc., so if you want to find a foreign refrigeration company to do cold storage for you, these things must be considered.

　　 Three. Factors of the price of cold storage:

　　 One: There are many kinds of cold storage boards

　　1. Color steel plate: strong anti-rust ability, no anti-corrosion ability

　　2, stainless steel plate: high-quality anti-corrosion, anti-rust material

　　3. Salted steel: beautiful appearance, with certain anti-rust and anti-corrosion ability

　　4. Polyurethane board refers to a polyurethane sandwich board made entirely of PU, or a combination of PU and color steel plate

　　Second: Temperature difference: The lower the temperature requirement of the cold storage, the faster the cooling speed, the higher the price, and vice versa.

　　 Third: Types of refrigeration units: Bitzer and Copeland are relatively well-known brands. The price is relatively higher.

　　Fourth: Geographical issues: If your cold storage is too far away, it will cause labor costs, cargo transportation costs, construction time, etc., which will cause the price to be different!

　　Other reasons affecting the price of cold storage:

　　 Presumably when everyone consults the price of cold storage, it will appear that the prices of cold storage provided by the company are different. What is the reason?

　　Difference analysis: high price: the number of installers, maintenance personnel, engineers, etc. of the company has increased.

　　 Low price: The staff of the company is relatively small, and various expenses are greatly reduced.

　　The advantage of high price: The engineer has more than 10 years of experience and has more exquisite cold storage design technology, which can make your cold storage temperature more accurate and the design more reasonable;

　　The installers are trained to be more professional in the steps of cold storage installation, with better sealing and aesthetics;

　　There are sufficient maintenance personnel. When your cold storage fails, you can rush to the site for emergency repairs as soon as possible to avoid unnecessary losses. The maintenance staff of our company have at least 4 years of age.

　　The disadvantage of low price: During the busy period of the business, there are not enough installation workers, so you can only spend money to hire temporary workers to do the work, so the installation method and technology are a lot worse;

　　 There is no after-sale guarantee. Small companies may close their doors at any time if there is a bad day, and there will be no after-sales business;

　　 There may be situations where the price is high and low: fake refrigeration equipment, such as refurbished units, second-hand units, etc.!

　　 Warm advice: Find a regular cold storage manufacturer for cold storage. Although the cost was a little higher at the time, the maintenance and repair of the cold storage will be guaranteed in the future!

　　 Fourth, the price of modified atmosphere preservation cold storage

　　 Modified atmosphere fresh-keeping cold storage has better fresh-keeping effect than fresh-keeping cold storage. Regardless of the fresh-keeping time and effect of cold storage, controlled atmosphere fresh-keeping storage is the best choice.

　　 Modified atmosphere fresh-keeping cold storage is still in its infancy in China. The domestic market for controlled-atmosphere storage is less than 20%, and most customers are still very new to controlled atmosphere fresh-keeping storage. Customers who have heard of modified atmosphere storage all know that modified atmosphere storage is good, but the specific advantages are still unclear; they also know that modified atmosphere storage is expensive, but why? Which is more cost-effective, controlled atmosphere storage or cold storage? In the customer's mind, there are a lot of rivers and lakes. Today, the editor of okmarts.com will start from the above questions and answer them one by one!

　　 What are the advantages of the modified atmosphere cold storage compared with the cold storage?

　　 Modified atmosphere fresh-keeping cold storage is more effective than traditional fresh-keeping cold storage. Modified atmosphere fresh-keeping cold storage is mostly used for agricultural and sideline products. The quality of the agricultural products taken out from the modified atmosphere cold storage is higher, because the unique atmosphere system of the modified atmosphere storage preserves the freshness of the products to the greatest extent. The fresh-keeping period of the modified atmosphere cold storage is longer. After the products of the modified atmosphere fresh-keeping warehouse are put into storage, the cold storage door generally does not open all year round. Therefore, the air-tightness of the air-conditioned cold storage is greater than that of any current cold storage. In addition, the air-conditioned system of the air-conditioned cold storage can well control the various components of the gas in the cold storage, so the fresh-keeping time of the air-conditioned cold storage is longer.

　　 Modified atmosphere cold storage is expensive? Where is it expensive? How to choose a modified atmosphere cold storage and fresh-keeping cold storage?

　　 Modified atmosphere cold storage and fresh-keeping cold storage under the same conditions, compared with the traditional fresh-keeping cold storage, only a set of modified atmosphere equipment, said that the air-conditioned fresh-keeping cold storage is expensive, but also expensive in this set of equipment. It should be pointed out here that generally a cold storage project only needs one set of air-conditioning equipment, that is to say, no matter how many cold storages the project has, only one set of equipment is required to share the same storage temperature.

　　 Therefore, the larger the air-conditioned cold storage, the lower the unit cost. In addition, the air-conditioned fresh-keeping cold storage has super tightness and heat preservation, so the equipment does not need to operate 24 hours a day all year round. Compared with the traditional fresh-keeping cold storage, the initial investment of the modified atmosphere fresh-keeping cold storage is more than that of the traditional fresh-keeping cold storage, but in the later operation, the modified atmosphere fresh-keeping cold storage is more energy-efficient and saves operating costs.

　　 5. Which type of cold storage has a lower price and cost

　　The cost of cold storage includes two parts, the construction cost of the cold storage and the operating cost of the later cold storage. Today, we will compare the cost of two types of refrigeration systems: ammonia refrigeration and fluorine refrigeration.

　　 What kind of cold storage construction price is low under the same conditions:

　　 Under the same conditions, the construction price of ammonia cold storage is cheaper than fluorine cold storage, but the procedure of ammonia cold storage construction is more complicated. Ammonia refrigeration is generally used in large-scale cold storage projects, and this type of cold storage is generally built in relatively open places. The ammonia cold storage must be submitted to the relevant department for review before installation.

　　 Fluorine refrigeration cold storage is lower in construction cost than ammonia refrigeration cold storage, and the construction of cold storage does not need to be submitted to relevant departments for review.

　　 Which cold storage has low operating cost under the same conditions:

　　Ammonia has twice the refrigeration capacity per unit volume of fluorine refrigerant, and the maintenance price of the daily required refrigerant is also cheaper than fluorine. For large-scale cold storage, the annual operating cost of cold storage is not a small expense, so until now many large-scale cold storage still use ammonia refrigeration system cold storage, but the safety of ammonia refrigeration has always been a difficult problem in China. The operating cost of fluorine refrigeration cold storage is higher than that of ammonia refrigeration cold storage, but there is no safety hazard. Therefore, almost all fluorine refrigeration systems are currently used in small cold storage.

　　 In recent years, there have been frequent ammonia accidents in cold storage. In 13 years, Shanghai Weng Brand Refrigeration Industry 8.31 major ammonia leakage accident, and in September of the same year, Xinjiang Tianye Group had another ammonia accident. The safety of ammonia refrigeration cold storage has once again become a hot topic in the industry, and the conversion of ammonia to fluorine in domestic cold storage will also become a trend in the next few years.

　　6. ​​Why is the price of cold storage installation so much different?

　　 At present, the cold storage installation industry market is still quite chaotic. Some businesses do not hesitate to lower the cold storage installation cost to win customers. The cold storage installation cost is reduced at the expense of the cold storage engineering quality and the trust of the cold storage. Why do you say that?

　　 The cost per cubic meter of small cold storage in the general standard in China is more than 1,000 yuan, and the cost per cubic meter of some large or super-large foreign-built cold storage can reach 5,000 yuan. The construction cost of those cold storages whose prices have been lowered ranges from several hundred yuan per cubic meter. Why is the gap so big?

　　 Let's start with the cold storage board. The thickness of the cold storage board, the density of each unit of the cold storage board and the material of the cold storage board, etc., all determine the price of the cold storage board, and also directly affect the refrigeration effect of the cold storage.

　　 Let’s talk about cold storage units. There are foreign brands and domestic brands in cold storage units. Generally, foreign brands are more expensive than domestic ones, but the cooling effect is better. Some cold storage manufacturers fool their customers and use some refurbished second-hand foreign units. The price difference between second-hand and brand-new units is very large. Secondly, it is difficult to guarantee the quality of refurbished units.

　　Finally is the installation process of the cold storage. The improper installation of cold storage units or cold storage panels will directly affect the cooling effect of the cold storage.

　　The difference in the installation price of cold storage is caused here. After reading the above content, I believe everyone should have a clear answer in their hearts. For cold storage installation, look for a large company with a good reputation. Although the cost of the early cold storage investment is a little bit higher, it saves a lot of trouble in the later stage, and the cold storage project is of good quality and well configured. The later use and maintenance of the cold storage can also save a lot of expenses.

　　 Seven, how to reduce the operating cost of cold storage

　　The operating cost of electricity consumption of large-scale rental cold storage directly affects the recovery efficiency of cold storage. The factors of cold storage energy consumption mainly include the performance of the cold storage refrigeration system, the selection of refrigerants, the selection of compressors, condensers and evaporators, the scale and layout of the cold storage, the type and thickness of the insulation layer of the cold storage, and the goods in and out of the cold storage. To improve the refrigeration efficiency of the cold storage, all factors should be considered.

　　 Energy-saving cold storage means to reduce energy consumption are usually divided into two parts: (1) reduce cold storage cooling load, (2) cold storage equipment selection.

1. Energy-saving fruit and vegetable cold storage in fruit and vegetable cold storage refers to the cold storage board, refrigeration unit, evaporator, etc., which are pre-manufactured in the factory, and installed on the agricultural production site to become an assembled cold storage or a civil cold storage or a semi-assembled and semi-civilized cold storage. And the storage capacity is generally less than 2003, which is used for cold storage for preservation and storage. Classified by design temperature, Guoshu mini cold storage is a high-temperature cold storage. Mini cold storage is composed of refrigeration system, warehouse, control system, etc.

　　 8. Factors affecting energy consumption of fruit and vegetable cold storage and cold storage energy-saving measures

　　1. Cold storage enclosure structure The cooling capacity of the cold storage through the enclosure structure is proportional to the unit heat flow of the cold storage enclosure structure. Therefore, more efforts should be made to reduce the unit heat flow index of the cold storage enclosure structure of the cold storage. To reduce the unit heat flow of the envelope structure, firstly, the thermal conductivity of the insulation material should be small, and the secondly, the envelope structure layer should be thicker. However, the thickness should generally not be too thick, otherwise problems such as increased construction costs and wasted space will occur. Therefore, insulation materials should be selected within a suitable thickness range. Under normal circumstances, insulation materials are required to have low thermal conductivity, low water absorption, good low temperature resistance, and the cost should not be too high.

　　The commonly used cold storage insulation materials include rice husk, polystyrene foam, polyurethane rigid foam and so on. Rice husk is convenient to obtain materials, but its thermal resistance is small, it is easy to absorb moisture, and the amount is large. The construction of the library body is time-consuming and cost-effective. The cost is not lower than polystyrene, the thermal resistance is large, and the price is moderate; polyurethane produced by tens of millions in Henan The cold storage board is easy to construct and install, has the largest thermal resistance, and the best insulation performance, but the price is relatively higher than that of the juben board.

　　2. Moisture and steam insulation of the cold storage enclosure structure It is also necessary to take moisture and vapor insulation measures for the cold storage enclosure structure, otherwise the insulation performance of the insulation material will deteriorate. This is the reason why the insulation performance of the cold storage body is good when it is first used, but the insulation effect becomes worse after a period of use. Since water vapor permeates from the high-temperature side to the low-temperature side, the moisture-proof vapor barrier layer should be placed on the side with the higher temperature of the insulation layer.

　　3. The evaporation pressure and temperature of the cold storage are corresponding to the evaporation pressure. After knowing the evaporation pressure, the evaporation temperature can be obtained by looking up the table. Under the condition of a certain temperature in the cold storage warehouse, the temperature difference (the difference between the evaporating temperature and the warehouse temperature) is reduced, the evaporating temperature can be increased accordingly, and the refrigeration capacity of the cold storage refrigerator will be increased, that is, the cycle efficiency will be improved. It also saves power.

4. Cold storage defrosting operation. Generally speaking, when the frost layer on the surface of the evaporator does not have significant resistance to the air, and the air flow through the evaporator has not been reduced, the effect of the frost layer is not serious, so it is not necessary to defrost as air When the flow rate is significantly reduced, defrost should be performed. The greater the humidity of the air, the greater the difference between the evaporator temperature and the cold storage temperature, the easier it is to frost on the evaporator. Combined with the preservation process, packaging and refrigeration can reduce the dry consumption of fruits and vegetables and reduce the number of evaporator defrosts. In fact, it also played a role in energy saving of cold storage.

　　5. The storage temperature of fruits and vegetables with different cold storage temperature and cold storage warehouse utilization is different, and each kind of fruit and vegetable also has a temperature range suitable for its storage. Without affecting the quality of fruits and vegetables, energy-saving cold storage should use a higher storage temperature. As the temperature of the cold storage is high, the evaporation temperature of the refrigeration system will increase accordingly, the refrigeration capacity of the refrigerator will be increased, and the cycle efficiency will of course be improved. Increasing the temperature of the cold storage is more importantly, it can also reduce the heat transfer through the storage body. The utilization rate of the energy-saving cold storage warehouse is the ratio of the actual volume of fruits and vegetables to the effective volume of the warehouse
