How should you look at the price difference of vending machines?
Effective volume
The signs of technical parameters of vending machines produced by high-quality manufacturers are all in accordance with national standards and in line with the random inspection of the national quality department to ensure the accuracy of the effective volume. However, other manufacturers often reduce the effective volume greatly in order to cut corners and materials, so that the promised to you cannot be achieved.
2. Fast cooling speed and constant temperature
When choosing refrigeration modules for vending machines produced by high-quality manufacturers, they choose suppliers with cost-effective brands to ensure that the refrigeration effect is good, and the best working temperature can be selected to keep the food storage machine fresh. The vending machines added by other manufacturers often have a long refrigeration time, and the temperature is not constant, one will be high and the other will be low, which will easily cause the food to deteriorate, and the customer experience is extremely poor. Now there is a problem of -18 degrees Celsius freezer on the market. When choosing, you need to pay special attention to whether it can really reach -18 degrees, because at this temperature, the shelf life of the food can be as long as 1 month, but some manufacturers take the time It is far from reaching this temperature when it is fully charged, causing losses during use. This is also one of the main reasons for the price difference.
3. High-power commercial compressors
In order to control the cost, many manufacturers have different choices in commercial compressors. The high-quality manufacturers have good starting performance in commercial compressors and complete specifications from small to large refrigeration. They can be configured according to different product requirements. It can guarantee the frequent start times and long running time of the machine.
4. material
The evaporation tubes of high-quality vending machines are all made of high-quality copper coils, and the panel is made of stainless steel. The surface is smooth and uniform in thickness. The high-quality plates can not only ensure the service life, but also make the appearance of the vending machine strong and flat. The use of copper pipes has better cooling effect and corrosion resistance than aluminum pipes or composite pipes. The copper tube has high cleanliness and fewer pipe joints, which can effectively prevent leakage or blockage in the refrigeration system and speed up the refrigeration speed.
5. Heat preservation
In the production process of the vertical wind cabinet of the vending machine, the thermal insulation performance of the insulation layer is not only a quality index, but also an important factor in the use of economy. In order to achieve good thermal insulation performance, appropriate raw materials must be selected, and the bulk density and cell diameter must be controlled within the optimal range. Therefore, it is necessary to use special fixtures that can adjust the material temperature and master the mature foaming process to produce a vending machine with good thermal insulation effect.
6. structure
The robustness of the cabinet structure of the vending machine is directly related to the life span of the display cabinet. There is an integral angle steel frame support between the outer shell and the inner tank of the high-quality vending machine, which greatly increases the firmness. After the door frame is completely welded and formed, the whole is foamed at one time, which avoids the defect that the cabinet door is easy to fall off due to the improper assembly of the door frame. The integral steel frame has obvious advantages in one-time forming, but some manufacturers often do not adopt this method in order to save costs.
