Application of food grade water pump in intelligent water dispenser

Water as one of the three main elements of human survival, no one can leave it. 50% ~ 60% of the body weight is composed of water, the water in the children body is even higher than 80%. It can be said that there is no life without water. With the improvement of people’s living standard, consumers have higher requirements for drinking water. Intelligent water dispenser also gradually enters people’s vision. So do you know how the smart water dispenser discharge water quickly? Next, the editor will explain the application of food grade water pumps in intelligent water dispenser.

What is an intelligent water dispenser ?

Intelligent water dispenser, as the name implies, is intelligent control of the water dispenser, also known as intelligent drinking table, intelligent boiling water system, intelligent water boiler and so on. This is different than ordinary bottled water products. It filters impurities in tap water through a filter, and then heats it to meet drinking standards. This smart application saves time and electricity, and deeply loved by people.

Function of Water Pump in Intelligent Drinking Water Dispenser
The water inlet of the intelligent water dispenser is connected with a water pipe, which finally reaches the standard of human drinking water through layer filtering, heating or cooling. After so many filtration and dilution, the pressure in tap water has already been reduced. When the drinking water reaches the water outlet, the pressure is already very weak, which directly affects the volume and speed of the water. Therefore, it is necessary to install a food grade water pump to pressurize the water to make drinking easier and more intelligent. This is the principle and effect of pressurization of food grade water pumps.

Features of  food grade water pump:

1. Food grade approved. All food water pumps have passed WRAS and FDA food certification, FDA is recognized as one of the largest food and drug regulatory agencies in the world with strict requirements; WRAS is a UK certification for drinking water safety.

2.Long term high temperature resistance. food grade water pump adopts international famous brand electronic components, which can ensure the stability and reliability of long-term high-temperature use. It also conducts targeted simulation and extreme high temperature continuous and intermittent tests to verify that it is fully reliable and suitable for the required range of liquid temperature of all intelligent drinking machine.

3.Small volume. The special high-performance structure design is adopted, with low power consumption, small size and easy installation, saving a lot of space for the water dispenser equipment.

4.Long life. The pump has a built-in frequency conversion brushless DC motor, which has no carbon brush wear problem, low power, small temperature rise, and a service life up to 30000 hours, reducing the worries of intelligent water dispenser manufacturers.

5.Low noise. Imported high-precision injection molded magnetic quiet rotor adopted, good noise batch consistency and stable accuracy controlling of long-term production. The maximum noise is ≤ 35dB (A), which is equivalent to the volume of whispering between you and others.

How to choose a food grade dc water pump

At present, there are many kinds of food-grade water pumps on the market, and it takes a little effort to choose them. So, how can you choose a pump that meets your needs, also known as your heart? Generally speaking, a good food-grade water pump must meet the following 5 points:

1. Food grade certified material
Because food-grade water pumps are used to transport food, beverages, and drinking water that customers drink. Therefore, all materials in direct contact with fluids must be food-grade certified materials, otherwise they are harmful to human health. Such as through WRAS, FDA food certification: FDA is recognized as one of the world’s largest food and drug management agencies, strict requirements; WRAS is the certification of drinking water safety in the UK.

2. Customized size and interface
According to the actual situation of the equipment, determine the size of the pump or the size of the space reserved in the equipment, and then consider whether it is a threaded interface or a Babaokou. It is also necessary to determine the direction of the water inlet and outlet, and the diameter of the pipe. According to the needs, the matching pump can be customized to maximize the performance of the pump and the equipment to achieve the best quality.

3. Cost saving
According to the application requirements, calculate the requirements for the working voltage, current, etc. of the food-grade water pump. Select the same voltage as the power supply mode of the device; select lower power consumption under the premise of guaranteed functions, etc. Choosing a pump whose performance is competitive enough for the application can save you a lot of money over choosing a more powerful pump.

4. High temperature resistance
Small household appliances such as hot drink machines and coffee machines transport high-temperature media for a long time. Therefore, when choosing a water pump, the ambient temperature and working fluid must be taken into account. For applications that require a 100°C operating temperature, a pump with a maximum operating temperature of only 50°C cannot be selected. And to consider the long-term, long-term high temperature food-grade water pump is the first choice.

5. Custom function
Choose a water pump that can realize customized functions, such as overvoltage protection, overcurrent protection, idling protection, PWM/5V intelligent speed regulation, speed feedback and other customized requirements.

What is a food grade water pump?

Food grade water pump refers to a brushless DC pump driven by a DC 6V ~ 24V brushless motor, and the material for making the water pump is food grade, and the whole water pump also reaches food grade certification.

·Application range of food grade water pump

Food-grade pumps are suitable for equipment that conveys food, beverages, and drinking water. Food-grade water pumps have long been widely used in coffee machines, boiling water machines, carbonated beverage machines, juice machines, and under-the-kitchen drink machines in Europe and the United States. In recent years, it has also been widely used in domestic hot drink machines, commercial carbonated drink machines, coffee machines and other small household appliances.

·Advantages of food grade pumps

Compared with traditional AC water pumps, food-grade water pumps using brushless motors have more advantages:
1. Using advanced DC frequency conversion technology, higher efficiency and lower noise;
2. Complete isolation between the motor and the liquid, static seal design, long-term use will never leak;
3. Built-in variable frequency brushless DC motor, no carbon brush wear problem, low power, small temperature rise, and a life span of more than 20,000 hours;
4. Adopt a proprietary high-efficiency structure design, with higher performance output, lower power consumption and small size;
5. High temperature resistance of 100 degrees Celsius, food-grade materials that meet FDA standards, and heat-resistant materials to meet the needs of the food or beverage industry;
6. A variety of power supply methods: Food safety water pumps can be powered by DC power, solar panels, and some can even be used as battery-powered water pumps, which can be driven by dry cells and batteries.
