In our daily life, we often come into contact with a lot of liquid packaging products, if your product is liquid, what do you need to consider before you buy a liquid packaging machine? Today to give you an explanation of the liquid packaging of the 4 important knowledge points need to pay attention to, which may be on your purchase of a fully automatic liquid packaging machine to provide a reference.
1. Judging the viscosity of the product is the key to liquid packaging
Although the liquid has fluidity, but there are fast and slow. Different viscous liquid is to choose different filling methods. Our filling methods are divided into 3 main forms, namely gravity filling (self-flowing filling), metering filling and pneumatic filling. However, how is the adhesion measured? The usual scientific method is to use a rotational viscometer to measure it, which is determined by the resistance received by the internal movement of the liquid, if the liquid receives more resistance within a certain speed, then the viscosity of this liquid is greater.
Does it seem like it’s complicated to you, if you don’t want to bother with calculations or measurements, you can send the liquid product directly to the factory that packages the machine and let them judge it, which may be one of the efficient ways to do it. Generally, the experienced factory will design the packaging program according to the characteristics of the product you provide, the common points and differences of the liquid.
So judging the viscosity of the liquid is the first step in your choice of filling method.
Filling types
Gravity filling does not require the use of a pump, but rather utilizes the natural gravitational properties of the liquid to flow from a high volume to a low volume. This filling method is suitable for products with good fluidity, such as water drinking non-viscous liquids mainly.
Metering filling is one of the most widely used filling methods in automatic liquid packaging machine. Further subdivided are flow meter filling, peristaltic pump filling, magnetic pump filling, syringe pump filling and gear pump filling and so on. These are all based on your liquid packaging accuracy needs.
Pneumatic filling utilizes the power provided by a pneumatic pump to press the liquid into the packaging container. Pneumatic pumps drive the flow of liquid through the pressure generated by compressed air and are suitable for liquids that require a certain amount of pressure to propel them into the packaging container, most commonly carbonated beverages are packaged in this form.
2. The temperature of the filling liquid will affect the speed of packaging
Can determine the viscosity of the liquid is next after the packaging. Packaging process, can not be avoided is different liquids at different temperatures are on the packaging speed, the answer is certainly there. Viscosity of the product in the high temperature environment fluidity will be faster, such as honey, honey with the temperature decreases, the viscosity increases, which is undoubtedly a difficult problem for manufacturers of packaging honey, but if the filling of honey in the device to add a heating device and stirring, is not a solution to the honey temperature decreases and lead to slower mobility, coupled with the stirring can be accelerated speed of the packaging.
Comprehensive example above, you need to consider is a liquid product at different temperatures will not change the fluidity, if the change is large, then you need to consider is to make the liquid packaging process more fluid by changing the temperature.
3. Liquid contains particles to choose different metering pumps
When you packaged liquid products contain particles, a mixture of liquid and particles, you can choose the appropriate pump according to the characteristics of the metering pump, the general liquid products have particles, we recommend that customers use the pneumatic pump. As the liquid contains particles, the pump diameter size also needs to be based on the size of your particles to decide, if the particles are large, the pump diameter is small, it will be easy to block.
If the liquid has no particles, only viscous, we recommend that customers use the magnetic pump can be, magnetic pump filling are generally pure liquid products.
4. Liquid packaging machines for different packaging form choices
Liquids on the market are packaged in bags and bottles. Liquid products are also varied, there are drinks, sauces, soups, functional drinks, washing liquids, nutrient solutions and pre-prepared dishes in the soup packet and so on. Which we often see in the takeaway small package of sauce bag is small size vertical form fill seal machine with liquid pump packaging machine packing and become, if there is a good-looking prefabricated bag packaging can choose the horizontal rotary bag packaging machine to pack and so on.
If it is bottled liquid which requires liquid filling machine and capping machine or capping machine integrated packaging machine to complete, the shape of the cans are also diverse, with different tracks to match your filling needs.
Automated liquid packaging solutions
We have more than ten years of fully automatic liquid packaging machine to see, can provide customers with our professional and experience, our liquid packaging solutions have the following cases:
- If it is irregular sachet packing for functional drinks, premade pouch packing machine is a good choice.
- If it is ketchup pouch packing, small VFFS packing machine is a liquid packing machine with the best cost performance.
- If it is a stand-up pouch with nozzle, we recommend a rotary packing machine with a capping machine.
- For one-time packing of multi-packs of finished products, our one-out-many series of horizontal bagging machine is a mass-production packaging machine with fast speed and higher efficiency.
If you want to know more about liquid design program, you can contact us, our engineers can design your own liquid packaging program.
