Ice machine principle:
At present, in the same category of ice machine, generally according to the output of the ice machine, the most important indicator is the 24-hour ice production, of course, under the ideal conditions of writing. You can determine the specific ice machine you need based on the number of people in your lab. The following chart is for production testing only:
Number of laboratories | Yield | model |
1-5 people | Ice making capacity: 30kg/24h | GYXH-30 |
5-10 people | Ice making capacity: 50kg/24h | GYXH-50 |
10-20 people | Ice making capacity: 90kg/24h | GYXH-90 |
More than 20 people | Ice making capacity: 200kg/24h | GYXH-200 |
Multiple labs | Ice making capacity: 500kg/24h | GYXH-500 |
Third, choose the capacity of the ice storage bucket
The capacity of the ice storage bin is also an important consideration in the selection of ice machines.
The number of people in the laboratory who are engaged in biological experiments determines the maximum amount used. Assuming that all people use it at the same time, the amount required is the largest. It is better that the amount of ice storage bins is the same as this amount. The ice machine is often fully automatic during operation. It does not require manual intervention and will automatically make ice. When the ice storage bin is full, the machine will automatically take a stop signal. Therefore, the amount of the ice storage bin is This is the maximum amount of ice that can be taken from this ice machine.
In view of the above factors, we can consider the selection from the following aspects:
1. If there are many people in the laboratory doing molecular biology related experiments, and often take ice at the same time, it is best to choose a model with a large amount of ice and a relatively large ice storage bucket (number of people x ice taking per time) );Such as:
equipment name | Grading | Ice making capacity kg/24h | Ice storage capacity kg |
GYXH-150 | Privilege Edition | 150 | 100 |
2. If there are many people in the laboratory doing molecular biology related experiments, but the probability of taking ice at the same time is small, then you can consider choosing an ice storage bucket with relatively small ice production and large ice storage, so that you can guarantee the use. It can also save on the purchase cost. Such as:
equipment name | Grading | Ice making capacity kg/24h | Ice storage capacity kg |
GYXH-50 | Privilege Edition | 50 | 40 |
equipment name | Grading | Ice making capacity kg/24h | Ice storage capacity kg |
GYXH-30 | Privilege Edition | 30 | 10 |
Fourth, choose imported or domestic brands
At present, when users choose ice machines or suppliers to recommend ice machines, they generally think that they are divided into imported or domestically produced camps. The subconscious will think that the quality of imports is good, stable and reliable.
According to our many years of experience, the ice machine is a very mature technology. There is no difference in technology between domestic and foreign products. The difference is often in the design, manufacture, after-sales service of different manufacturers, unreasonable design or cost. The first consideration led to various problems in the application process, and the unsound system of the after-sales system exacerbated the bad impression. In recent years, domestic manufacturers have realized some problems in the market, and the concept has been changing. All aspects have been working hard to build a brand and have achieved good results.
Among the imported brand products, price and after-sales service are their shortcomings. In terms of price, it is an indisputable fact that imported products are several times higher than domestic products.
Common brands:
Imported brand: scotsman Grant Sanyo Manitowoc. . . . . .
Domestic brands: Xiamen Guoyi, Shanghai Birang, Changshu Xueke, Ningbo Xinzhi, Taicang Huamei, Beijing Changliu, Beijing Bo Yikang. . . . . . (Many of the brands are found in other OEM OEMs)

Hardware articles
The hardware of the snowflake ice machine mainly includes a compressor, a motor, a motherboard, and the like.
The best brands of compressors are Danfoss (Secop Cope in China) [such as Xiamen Guoyi Ice Machine], followed by some American Copeland, French Taikang, Sanyo, etc. [such as sanyo ice machine], and some use. Other brands such as Zanussi [such as Changshu Xueke Ice Machine]. The quality of Danfoss is widely recognized in the industry, and the price is generally 3-5 times that of other brands.
Motor: Snowflake ice machine requires a motor to drive ice after ice formation in the freezer compartment. Motors need to be driven, so the quality of the motor has a great impact on the quality, life and stability of the snowflake ice machine. At present, in the motor used in the snowflake ice machine on the market, the first thing to look at is the type of motor, such as a right-angle hollow or a worm gear reducer. Generally, a motor with a right-angle hollow reducer is preferred (such as JSCC). Precision motor products are mainly based on German brands, and Germany is known for precision industry. There are also quite a few snowflake ice machine brands in China that use Haitec, Ningbo Zhongda Motor or South Korea's motors, and the relative recognition will be lower.
Main board: At present, most ice machine brands in the market use the ready-made control panel on the market, which is almost the same as the catering process. Generally, the display status of the display light is lacking in safety control and design; the better one should be suitable for experiment. The dedicated main control board of the room use environment, such as voice broadcast or liquid crystal display, and designed in the program to avoid common problems such as ice skate jam. Xiamen Guoyi has done a good job in this regard.
Performance articles
The ice from the snowflake ice machine should be relatively broken, which can greatly increase the contact area of ​​the sample tube and enhance the effect of the ice bath. In addition, it should have a certain water content to improve the heat preservation capacity.
In the case of a certain amount of ice production, theoretically speaking, the larger the capacity of the ice storage bucket, the better, so this factor should be considered when considering performance.
The operation of the snowflake ice machine has been highly automated, with minimal manual intervention. Users often encounter some situations during use. In this case, the machine itself needs to provide a better alarm or prompt, such as the indicator light used by most ice machines, or buzzer, or voice prompts. In the abnormal state of ice, water shortage, standby, and downtime, the user can be notified in time and effectively. Even the related products are equipped with a liquid crystal screen to display various states during the operation of the ice machine, so that the user can see at a glance.
On the basis of each hardware, the stability of the overall operation of the ice machine is the most important. Program control and various error-proof programs and sensors are the core of the operation. For example, the ice skate is a common fault of the snowflake ice machine. It is very important to stop the ice skates at the two points of shutdown and start-up.
Price article
In terms of price, the benevolent sees the wise and sees wisdom. The fact that most people are reluctant to face up is: one penny and one share. Even if Internet thinking is popular now, there are a lot of free products, and when you use free products, providers only get their profits in a way that you can't detect, or the associated third party pays for this cost. In the traditional instrument manufacturing industry, the cost of hardware is still rigid, and no manufacturer can say that it is free to use.
According to the current market situation, the current price of imported brand products of snowflake ice machine is generally 2-5 times of domestic products, or even higher; among domestic brand products, Xiamen Guoyi (exclusive version) and Shanghai ratio Lang, Ningbo Xinzhi, Beijing Changliu, etc. are highly priced, and Xiamen Guoyi (Standard Edition) and Changshu Xueke are underpriced. The positioning of the price is related to the supplier's production method, product positioning, material selection, warranty, etc. If OEMs are used to find other manufacturers to OEM, the relative sales price will definitely be higher, otherwise reasonable profits cannot be guaranteed.
In general, when comparing prices, we should fully consider the production methods, product positioning, material selection, warranty, etc. of each supplier, and choose a suitable price and product according to their actual conditions. From the current brand on the market, a domestic brand with its own production capacity, quality, and after-sales service is a good choice.
Six, snowflake ice machine FAQ
1. What is the difference between a catering ice machine and a laboratory snow machine?
The ice maker for catering is generally made of ice cubes, bullets, etc. The ice is formed in a ready-made mold when it is formed. The snowflake ice machine has a complete set of refrigeration in terms of hardware. In addition to the system, a motor-driven ice knives system is required for the smashing of the ice. The ice knives are always running, and the ice formed in the ice chamber is continuously scraped out and squeezed into irregular crushed ice. Therefore, in terms of hardware cost, the snowflake ice machine has a higher manufacturing cost than the ice machine for catering because of a complete set of motor and ice knives.
2. Why is the ice machine on Taobao so cheap?
Most of the ice machines on Taobao are ice machines for catering purposes, that is, ice cubes or bullets, so the price will be lower, but if you search for the products displayed by the "snow machine", you can also watch The price will be higher than other types of ice machines, mainly due to the difference in hardware costs.
3. What is the difference between the imported brand of snowflake ice machine and domestic brands?
From a technical point of view, there is no gap between imported brands and domestic brands, refrigeration technology is very mature, and the history of commercialization is very long;
From the hardware point of view, the compressors, motors, etc. used by foreign brands, except for some of their own brands, the hardware of other ice machine brands is almost to find the big brands of compressors, motor brands OEM or direct purchase, and Most of the hardware manufacturers have joint ventures or wholly-owned production plants in China, so there is no gap in hardware;
From the perspective of comprehensive quality control, foreign brands have certain advantages. After all, the brand has a long history, large capital and scale, and strong technical means;
Domestic brands generally have an advantage over imported brands in terms of price and after-sales service convenience;
In general, the trend of most users to purchase snowflake ice machines has been biased towards domestic brands, and price/performance ratio is the most important factor.
4. Why are the brands of many brands of ice machines similar?
Why are many brands of snowflake ice machines at home and abroad basically the same? The main reason is that most brands use OEMs, which is to find others to help produce, and then stick their own brands. It is the cost that does not need to be put into production and management. It only needs to take advantage of its own channel and make sales well. It belongs to the mode of light asset operation. OEM production mode is widely used in consumer electronics products, such as the familiar Apple mobile phone, Foxconn is his largest processing plant, this model is built on the brand's brand is very strong, and has a strong product design and quality control capabilities . In contrast, the snowflake ice machine industry, most of the brands of manufacturers are not large, the basic process that can be done in the OEM process is that I pay, you produce, I sell the brand, there will be many problems in this process. For example, because the brand has no technical strength, the design and quality control of the product can't be carried out. It can only be ordered by the OEM, or just by the products produced by the OEM. It is exactly the same, so that the brand can be branded. Therefore, many products of different brands with almost the same appearance will be seen on the market. It is conceivable that because of the technical strength of the brand, the brand has to rely entirely on the OEM for after-sales, and its support ability is very limited.
5. Which brand of compressor is good?
The best brands of compressors are Danfoss (Secop Cope in China) [such as Xiamen Guoyi Ice Machine], followed by some American Copeland, French Taikang, Sanyo, etc. [such as sanyo ice machine], and some use. Other brands such as Zanussi [such as Changshu Xueke Ice Machine]. The quality of Danfoss is widely recognized in the industry, and the price is generally 3-5 times that of other brands.
6. Typical target users?
In the laboratory field, the two most typical types of customers are molecular biology laboratories or protein purification laboratories. See the link:
Instrument configuration required for molecular biology laboratories
Equipment required for protein purification laboratory
All laboratories that intersect with these two fields are potential users. Of course, snowflake ice machines are also used in some areas such as catering or food processing.
Viruses and bacteria are everywhere. Preventing them in advance is the best way to reduce the risk of infection. Wearing a mask and washing hands frequently are crucial. The new type of coronavirus has the characteristics of contact transmission, and the fact that the virus exists on the doorknob of patients with pneumonia has also shown the necessity of paying attention to hand hygiene and wearing disposable protective gloves.
Whether it is going out to purchase daily necessities or buying through online platforms, it is inevitable to come into contact with "foreign" items, such as supermarket shopping carts, packaging bags, express packaging boxes, etc., and more things need to be touched after resuming work, such as It is inevitable to take public transportation, elevators, etc., these places may have been touched by patients or suspected patients. Wearing disposable protective gloves is an effective means to reduce the risk of infection when there is no condition to wash your hands at any time.
