Description

Technical Field

[0001] The invention relates to the technical field of food packaging, and in particular to a food packaging machine which is convenient for loading. Background Art

[0002] Food packaging is an integral part of food commodities. It protects food and prevents it from being damaged by biological, chemical, and physical external factors during the circulation process from the factory to the hands of consumers. It can also maintain the stable quality of the food itself. It facilitates the consumption of food and is the first to show the appearance of food and attract consumers. It has value beyond material cost. Therefore, the food packaging process is also an inseparable part of the food manufacturing system engineering, but the versatility of the food packaging process also gives it a relatively independent self-system.

[0003] In the prior art, granular canned food often needs to be transported using an auger-type conveying device when it is packaged. When granular food is transported, the particle sizes of products made from different ingredients are different. Therefore, the gap requirements between the auger and the tube wall of the storage tank are also different during transportation, so as to avoid the phenomenon that the food material is scattered and cannot be transported upward due to the gap being too large. The existing auger and storage tank usually have a fixed gap when in use, and a single auger is usually only used for food material of a single particle size during transportation. When food material of different particle sizes needs to be replaced for packaging, the gap between the auger and the storage tank is not easy to meet the feeding requirements, which will affect its use effect.
