Analysis of the process flow of puffed yam powder production line
1、 Raw material preparation
1. Yam procurement and acceptance: Fresh and pest free yam is selected as the raw material for warehouse acceptance to ensure that the quality of yam meets processing requirements.
2. Cleaning and screening: Thoroughly clean the yam to remove soil and impurities from the surface, and screen to remove the skin and roots from the yam surface while retaining the fleshy portion.
2、 Preliminary processing
1. Chopping: Cut and crush the cleaned and screened yam to improve subsequent processing efficiency and product quality.
2. Soaking: Soak the chopped yam in water, usually for 24-48 hours, to remove unnecessary liquids and impurities, and optimize the color and taste of the yam.
3、 Pre treatment of puffing
1. Screening: After soaking, yam should be screened with a mesh to separate different specifications of granular yam for subsequent puffing processing.
2. Drying: Use a dryer to dry the screened yam particles, reducing their moisture content to around 6-8% to ensure product quality and taste during the puffing process.
4、 Puffing processing
1. Expander operation: feed the dried yam granules into the extruder. Through the action of high temperature, high pressure and high shear force, the yam starch granules are expanded and essence is extracted. The starch molecular chain is opened, which increases the surface area of food granules and improves the digestibility. At the same time, this process also causes the protein peptide chain to break down into peptides and amino acids, greatly improving the protein absorption rate.
2. Expanded product transportation: The expanded yam particles are transported to the next step for processing through equipment such as air conveyors or elevators.
5、 Subsequent processing
1. Crushing: The puffed yam particles are sent into a grinder for grinding treatment, making them into delicate yam powder. According to market demand and different customer requirements, different levels of processing can be carried out.
2. Packaging: Packaging the processed yam powder, usually in the form of plastic bags or barrels, to facilitate product sales and preservation.
6、 Characteristics of the production line
1. High degree of automation: The puffed yam powder production line adopts advanced automation equipment, which improves production efficiency and reduces labor costs.
2. Stable product quality: Through precise temperature control and process design, ensure the stable quality of puffed yam powder and meet market demand.
3. Strong flexibility: The production line can adjust product specifications and shapes according to market demand to adapt to market changes.
4. Efficient and energy-saving: The production line equipment is configured reasonably, and key links such as drying and puffing are all equipped with efficient and energy-saving technologies, reducing energy consumption.
Summary: The process flow of the puffed yam powder production line includes raw material preparation, preliminary processing, pre puffing treatment, puffing processing, subsequent processing, and production line characteristics. Through scientific process design and advanced equipment configuration, efficient processing of yam and production of high-quality products have been achieved.
