Different manufacturers may adjust this process according to their equipment configuration and product requirements.
4. Detailed Mimi Shrimp Snack Production Process
Step 1: Raw Material Preparation
Before production begins, manufacturers need to inspect and prepare all raw materials.
Wheat flour, starch, shrimp powder, and seasoning ingredients should be weighed accurately according to the product formula.
Powdered ingredients may need to be sieved to remove impurities and break up lumps. This helps ensure uniform mixing and prevents foreign materials from entering the production line.
The moisture content and quality of the raw materials should also be checked before processing.
Step 2: Mixing
The prepared ingredients are transferred into a mixing machine.
During this stage, flour, starch, shrimp powder, salt, and other dry ingredients are blended thoroughly. Water is then added gradually to achieve the required moisture content.
Uniform mixing is essential because uneven ingredient distribution can cause inconsistent expansion, flavor differences, and unstable product quality.
Manufacturers should pay particular attention to water addition. Excessive moisture may affect extrusion performance, while insufficient moisture can make the material difficult to process.
Step 3: Extrusion
Extrusion is one of the most important stages in Mimi shrimp snack production.
The mixed materials are fed into an extruder, where they are conveyed, compressed, heated, and processed under controlled mechanical and thermal conditions.
Inside the extruder, the screw pushes the material forward while friction and external heating help form a plasticized mass.
The material is then forced through a specially designed die to obtain the required shape.
The extrusion process affects several important product characteristics, including:
- Product expansion rate
- Internal pore structure
- Shape and dimensions
- Texture and crispness
- Production efficiency
Manufacturers need to select suitable screw configurations, die designs, temperatures, and screw speeds according to the product formula.
Step 4: Cutting and Shaping
After extrusion, the product is cut into the required lengths and shapes.
A rotary cutter or other cutting device can be used depending on the production line design.
The cutting system should operate smoothly to ensure consistent product dimensions.
Accurate cutting not only improves the appearance of Mimi shrimp snacks but also makes subsequent drying and frying more uniform.
Step 5: Drying
Freshly extruded products usually contain considerable moisture and therefore need to be dried before further processing.
A continuous belt dryer is commonly used in industrial snack production.
During drying, hot air passes through the product layer to remove excess moisture. Temperature, drying time, air circulation, and material thickness all influence the final result.
Proper drying helps:
- Reduce moisture content.
- Improve product stability.
- Prevent deformation during subsequent processing.
- Promote consistent frying or baking.
- Improve final product crispness.
It is important to avoid excessive drying, which may cause cracking or negatively affect the final texture.
Step 6: Frying or Baking
Depending on the product design, dried Mimi shrimp snack pieces can be fried or baked.
Frying process:
Frying in vegetable oil allows the snack pieces to expand further and develop a crispy texture. Oil temperature, frying time, and product moisture content must be carefully controlled.
If the oil temperature is too low, the products may absorb excessive oil. If it is too high, the surface may become overly dark before the inside reaches the desired condition.
Baking process:
Some manufacturers choose hot-air baking as an alternative to frying. This method can reduce the amount of added oil and produce a different texture.
The appropriate processing method depends on the desired flavor, product positioning, and market demand.
Step 7: Seasoning
Seasoning gives Mimi shrimp snacks their distinctive taste.
After frying or baking, the products are transferred into a seasoning machine, such as a rotary seasoning drum.
Flavoring powder is evenly distributed over the snack surface through continuous rotation and mixing.
Common seasoning options include:
- Original shrimp flavor
- Spicy shrimp flavor
- Barbecue flavor
- Cheese flavor
- Tomato flavor
- Garlic flavor
The amount of seasoning, spraying rate of oil or liquid flavoring, and mixing time should be controlled carefully.
Uniform seasoning improves product consistency and consumer acceptance.
Step 8: Cooling
After seasoning, the snacks should be cooled to room temperature before packaging.
A cooling conveyor can help remove residual heat and stabilize the product texture.
Packaging products while they are still hot may cause condensation inside the package, increasing moisture content and reducing crispness.
Therefore, sufficient cooling is essential for maintaining product quality and shelf life.
Step 9: Packaging
The cooled Mimi shrimp snacks are transferred to an automatic weighing and packaging machine.
Common packaging formats include small individual bags, medium-sized retail packages, and large family packs.
Packaging materials should provide effective moisture and oxygen barriers to help preserve freshness, flavor, and crispness.
Manufacturers should also ensure that each package has an accurate net weight and clear product labeling.
