How to choose the packaging machine equipment that suits you? Today, we will start with the measurement method of packaging machines and introduce the issues that should be paid attention to when purchasing packaging machines.

At present, the measurement methods of automatic packaging machines include counting measurement method, microcomputer combination measurement method, screw measurement method, measuring cup measurement method and syringe pump measurement method. Different measurement methods are suitable for different materials, and the accuracy is also different.

1. Syringe pump metering method

This measurement method is suitable for liquid materials, such as ketchup, cooking oil, honey, laundry detergent, chili sauce, shampoo, instant noodle sauce and other liquids. It adopts the cylinder stroke measurement principle and can adjust the packaging capacity arbitrarily. Measurement accuracy <0.3%. If the material you want to package is liquid, the most popular one at present is the liquid packaging machine with this metering method.

2. Measuring cup measurement method

This measurement method is suitable for the small particle industry, and it is also a small particle material with a relatively regular shape, such as rice, soybeans, white sugar, corn kernels, sea salt, edible salt, plastic pellets, etc. Among the many current measurement methods, it is relatively cost-effective and has high measurement accuracy. If you want to pack regular small granular materials and also want to save some money, then the measuring cup metering granule packaging machine is the most suitable solution for you.

3. Screw measurement method

This measurement method is often used for powdered materials, such as flour, rice rolls, coffee powder, milk powder, milk tea powder, seasonings, chemical powders, etc. It can also be used for small particle materials. It is also a widely used measuring method, but if you do not have such high requirements for packaging speed and accuracy, you can consider a measuring cup measuring powder packaging machine.

4. Microcomputer combination measurement method

This measurement method is suitable for irregular block and granular materials, such as candies, puffed foods, biscuits, roasted nuts, sugar, quick-frozen foods, hardware and plastic products, etc.

(1) Single scale. Using a single scale for weighing has low production efficiency, and the accuracy will decrease as the weighing speed increases.

(2) Multiple scales. Using multiple scales for weighing can greatly improve production efficiency, and is especially suitable for high-precision measurement of coarse and lumpy materials. Its error will not exceed ±1% and it can weigh 60 to 120 times per minute.

The microcomputer combined weighing method was developed to address the problems existing in the traditional weighing method. Therefore, if you have high requirements for packaging accuracy and speed, you can choose a weighing packaging machine with this measurement method.
