In the huge system of food industry, food packaging is the key link connecting production and circulation. The grain harvested from the field can enter the market after packaging and realize its economic value. As a special equipment for food packaging, food packaging scales play a vital role in ensuring food security and improving packaging quality.
Grain has unique physical properties, such as a variety of grain shapes, round, long and so on; The grain texture of some grains is soft and easy to be damaged in the packaging process. Moreover, the grain has higher requirements for the storage environment, which is easy to be damp and insects, which puts forward special requirements for the sealing and moisture-proof and insect-proof performance of the packaging. In the design of grain packaging scale, these characteristics are fully considered, and a series of targeted measures are adopted. In the selection of packaging materials, materials with good moisture-proof and insect-proof properties are selected to effectively block the invasion of external moisture and pests. At the same time, in the packaging structure design, the packaging sealing method is optimized to ensure that the sealing of the packaging is good, and the loss of food in the storage and transportation process is reduced.
In large grain storage enterprises, the application of grain packaging scale is very common. The daily grain throughput of such enterprises is huge, and there are high requirements for packaging efficiency and packaging quality. With the help of advanced automatic control system, food packaging scale can quickly adapt to the packaging needs of different kinds of food. Taking wheat packaging as an example, the size and density of wheat particles are relatively uniform, and the packaging scale can quickly and stably load wheat into the packaging bag according to the preset packaging weight through a reasonable feeding device and conveying system. Moreover, in the packaging process, the weight of the packaging is monitored in real time by the sensor, and once the weight deviation is found, the feeding speed is adjusted in time, so that the weight of each bag of wheat can be better maintained within the specified range. After many grain storage customers introduce a new type of grain packaging scale, the weight fluctuation in the packaging process is significantly reduced, the packaging efficiency is improved, and the food loss caused by packaging problems is greatly reduced, ensuring the storage and circulation of food safety.
