1. Raw material processing

The production line of puffed snack food usually uses a variety of grains (such as flour, corn, etc.) as the main raw materials. The processing of these raw materials on the production line is relatively simple and uniform. After being homogenized and mixed by the powder mixer, the raw materials enter the puffing machine for high temperature and high pressure treatment. In contrast, the raw material processing of other food production lines (such as dairy and meat product production lines) is more complicated, which may involve multiple steps such as raw material screening, cleaning, cutting, and pickling. In addition, the raw materials are diverse and the requirements for equipment are higher.

2. Production process

The production process of this production line is relatively simple, mainly including raw material mixing, extrusion puffing, forming and cutting, frying (or baking) deoiling, seasoning and other steps. Among them, extrusion puffing is the core link, which uses high temperature and high pressure to instantly depressurize the raw materials to form porous and soft puffed food. This process not only improves the taste and flavor of the food, but also reduces energy consumption and production costs. Other food production lines, such as baking production lines, may include multiple complex steps such as dough preparation, fermentation, baking, cooling, etc., and each step requires precise control of parameters such as temperature and humidity.

3. Equipment Configuration

The equipment configuration of the leisure puffed snack food production line is relatively concentrated, mainly including key equipment such as powder mixer, screw conveyor, twin-screw puffer, frying (or baking) machine, seasoning line, etc. Most of these equipment adopt automatic control, which is simple to operate and easy to maintain. In contrast, the equipment configuration of other food production lines is more complex and diverse. For example, the dairy product production line may include homogenizer, sterilizer, filling machine, etc., and the meat product production line may include meat grinder, marinating machine, smoker, etc. The selection and use of these equipment needs to be customized according to the production process and market demand of specific products.

4. Product Features

Puffed snack foods are crispy, easy to digest, have a special aroma, and are easy to carry. They are ideal snack foods for consumers. These characteristics are mainly due to their special production process and raw material processing. Other foods, such as dairy products and meat products, have their own special nutritional value and flavor characteristics. For example, dairy products are rich in protein and calcium, while meat products are rich in high-quality protein and fat.

5. Market Application

This production line is widely used in the snack food market because of its wide variety of products, good taste and low cost. These products not only meet the taste needs of consumers, but also have certain health value. In contrast, the market application of other food production lines is more extensive and diverse. For example, dairy products produced by dairy production lines are widely used in breakfast, beverages, desserts and other fields; meat products produced by meat production lines are common ingredients for family tables and fast food industry.

6. Summary

There are significant differences between the casual puffed snack food production line and other food production lines in terms of raw material processing, production technology, equipment configuration, product characteristics and market applications. These differences make different food production lines play special roles and values in their respective fields. However, with the continuous development of food technology and changing consumer needs, the boundaries of various food production lines are gradually blurring. In the future, food production companies will pay more attention to technological innovation and cross-field cooperation to develop more new products that meet market demand.
