What aspects should be considered when choosing a leisure food production line?

The snack food production line is a highly popular equipment in the current market. The extruder integrates multiple functions such as compression, mixing, kneading, shearing, melting, sterilization, expansion, and molding, completing all processes in a very short time. By changing the molds, the shape and size of the products can be infinitely varied. It has a wide range of applications in producing puffed food (pet food, fish feed, etc.).

The snack food production line not only changes the shape and state of raw materials but also alters the molecular structure and properties of the materials, forming certain new substances. When grains are placed in an expander, as heating and pressurization proceed, the moisture in the grains becomes superheated, and the grains themselves become soft. When a certain high pressure is reached and the expander lid is opened, the high pressure rapidly returns to normal pressure. At this moment, the superheated moisture inside the grains instantly vaporizes and undergoes a violent explosion. The immense expansion pressure not only destroys the external shape of the grains but also breaks the internal molecular structure, cutting insoluble long-chain starch into water-soluble short-chain starch, dextrin, and sugar. As a result, the insoluble substances in puffed food decrease, while the water-soluble substances increase.

Based on recent industry development demands, the snack food production line can be considered from the following four aspects:

1. Scale applicability. The equipment used by puffed food processing enterprises in China is mainly divided into three scales: large, medium, and small. 2. Safety applicability. Safety applicability refers to mechanical safety, production safety, and food safety in puffed food processing. 3. System applicability. System applicability is an important link to ensure continuous operation, balanced production, processing performance, and product quality. 4. Hygiene applicability. It refers to the hygiene requirements for mechanical structure in the design and manufacturing process of puffed food machinery, mainly including structural materials, surface construction, cleanability, durability, and inspectability of product contact surfaces and non-product contact surfaces.
