What are the specific types of packaging scales used to weigh grain? What are the differences and scope of application between different types? With these questions in mind, let's summarize:

Each of the following classifications includes both single scale and double scale. Generally, loading grain requires high speed, and double scale is more common.

1. Firstly, from a technical perspective, it can be divided into pneumatic scales and electric scales. Pneumatic scales are a traditional method of packaging scales, while electric scales have only emerged in recent years. Electric scale technology is more advanced.

2. From the appearance, there are those with and without a mobile room. The main purpose of a mobile room is to keep warm and prevent machine components from stopping due to extremely low temperatures. It is generally suitable for use in Northeast China and can still function normally even at minus 20 degrees Celsius in winter.

3. From the perspective of automation, it can be divided into one person operation and two person operation scales. Of course, all scales can be operated by one person, but the speed may be slow. The term "one person operation" here actually refers to automatic sewing, eliminating the need for one sewing operator. One person operation is currently the highest level of automation for grain quantitative packaging scales. Of course, the distinction between one person operation and two person operation for grain packaging scales is not conflicting with the above two types. One person is required to operate the grain packaging scale, and one person is dedicated to bagging. The remaining sealing work is completed by an automatic bag clamping guide and traction mechanism for sewing. All individuals did not experience a decrease in operating speed.
