Summer is coming soon, and commercial freezers will soon become a common player in the purchase list of each unit. Commercial freezers that have been used for a long time may have problems such as poor cooling, water leakage, poor door seals, and increased noise. Today is A chao detailed commercial freezer procurement strategy, and also found some good quality commercial freezers for you, the code word is not easy, if it is useful, just double-click it!
First, understand the types of commercial freezers
1. Distinguish by style
At present, there are many styles of commercial freezers on the market, but the main styles are horizontal and vertical. Vertical down can be subdivided into four and six doors.
The horizontal type takes up more space, and the price is cheaper than the vertical type. In terms of function, most of them are mainly frozen, and the lid needs to be removed to take it, which is troublesome.
The vertical type is not much different from a household refrigerator. In terms of function, it can be fully frozen, fully refrigerated, or half refrigerated. The price depends on the quality, and the gap from cheap to expensive is relatively large.
2. According to the refrigeration method
There are three main cooling methods for freezers: direct cooling, air cooling, and mixed cooling.
● Direct cooling: directly adopts the compression refrigeration method, and cools the air through the refrigeration device to complete the refrigeration process. Direct cooling has fast cooling speed and good cooling effect. It is suitable for commercial freezers that store a large number of items, but its cooling efficiency is relatively low and it is prone to frost. need regular defrosting
● Air-cooling: The air is circulated through two air ducts inside and outside to make the temperature inside the machine uniform, so as to achieve the purpose of cooling. Air-cooled cooling has high cooling efficiency, fast cooling speed, and is not prone to frost, but the cooling power consumption is relatively high.
● Mixed cooling: Direct cooling and air cooling are used at the same time. This refrigeration method can take into account the advantages of direct cooling and air cooling, the cooling efficiency and speed are good, and it can avoid the frost problem that occurs in direct cooling. However, the structure of the mixed cold freezer is relatively complicated, and the cost is relatively high. It is generally a high-end product.
3. According to the material
At present, the materials on the market mainly include copper tube refrigeration, aluminum tube refrigeration, and copper-aluminum composite tube refrigeration, each of which has its own advantages and disadvantages.
● All-copper tube refrigeration: Copper tube has good thermal conductivity and high cooling efficiency; it also has the characteristics of strong corrosion resistance and oxidation resistance and long service life; it can withstand high pressure and temperature changes.
● Aluminum tube refrigeration: Compared with copper tubes, aluminum tubes are cheaper, light and easy to install, but aluminum tubes have poor thermal conductivity and cooling efficiency is not as good as copper tubes.
● Copper-aluminum composite tube refrigeration: The copper-aluminum composite tube refrigeration method combines the advantages of copper tubes and aluminum tubes, which can not only reduce refrigeration costs, but also improve thermal conductivity, but the production process is relatively difficult, and it is still relatively rare in the market.
Second, how to choose the freezer that suits you
1. Confirm the demand
First of all, you should clarify what items you usually freeze, whether you should choose full freezing or full refrigeration. After confirming the above two, confirm how much capacity you need.
Many people still have a relatively low concept of their own needs. I will use the capacity of 900L as an example. Of course, the following values are only estimates. The actual storage capacity will vary according to the size and shape of the item.
● A 900-liter commercial freezer can store about 450 kg of beef or pork.
● If it is chicken, it may need more space as chicken is usually larger than beef or pork. So a 900 liter commercial freezer can hold approximately 250-300 whole chickens.
● For ribs, if they are whole pieces, then a 900-liter commercial freezer can store about 120-150 kg of ribs.
● If it is seafood, such as shrimp, fish, etc., then a 900-liter commercial freezer can hold about 100-150 kg.
● If it is vegetables or fruits, the specific capacity will vary due to the type and size, but a 900-liter commercial freezer can usually meet the needs of small and medium-sized restaurants.
The above content is also for reference only, and the actual capacity may vary due to factors such as item size, layout and design. If you feel that it is still difficult to control the purchase, it is better to consult the relevant customer service personnel for estimation.
2. Later maintenance cost
Although commercial freezers are working all year round, they need to be cleaned regularly because they need to store a variety of foods. If you purchase a direct cooling freezer, you may need to do regular defrosting;
If you use an air-cooled freezer, there is no regular defrosting work, but you also need to do a certain amount of daily cleaning. If you don’t defrost and clean properly, you will save a lot of worry.
3. Need to determine the budget range
Considering many aspects, from materials to innovative designs in various details, the price span of commercial freezers is still relatively large, and it can only be roughly divided into intervals.
● Mid-range commercial freezer: the price is between 1000-5000 yuan. This kind of commercial freezer is generally of good quality and high cost performance, and is more common in small and medium-sized catering establishments.
● High-end commercial freezer: the price is between 5000-10000 yuan. This kind of commercial freezer usually has more functions and higher performance, such as greater cooling capacity, better heat preservation performance, etc., and is suitable for use in high-end places such as hotels and large restaurants.
● Ultra-high-end commercial freezer: the price exceeds 10,000 yuan. This kind of commercial freezer is usually designed for specific industries or special purposes, such as hospitals, laboratories and other places that require extremely high requirements.
