(1) The processing flow of puffed food:
1. Baking type puffed food production process: powder making → steaming → forming → primary drying → maturation → secondary drying → baking → seasoning → packaging.
The production process from the production form of semi-finished products to finished products: baking→seasoning→packaging.
2. The production process of fried puffed food: flour-making → steaming → forming → drying → frying → seasoning → packaging.
The production process from the production form of semi-finished products to finished products: frying → seasoning → packaging.
3. Direct extrusion type puffed food production process: powder making → mixing → extrusion puffing → shaping → baking → seasoning → packaging.
4. Color type process flow: refer to its blank production process flow (which can be divided into baking type, fried type or extrusion type), * add a coloring process after *.
However, in actual production, various technological processes are mixed and supplemented with each other to achieve the perfect effect of the product.

(2) Key link:
Baking type: steaming, drying, baking.
Fried type: steamed, dried, fried.
Direct extrusion type: extrusion, puffing, baking.
(3) Quality and safety issues that are prone to appear.
1. The mouthfeel is not crispy: If the moisture content of the blank is too high, the finished product will have poor puffing effect, and the mouthfeel will be easy to be not crispy.
2. Carbon coke appears on the surface of the product: the temperature of baking and frying is too high; the time is too long.
3. Microorganisms exceed the standard, and the environment of the product inner packaging workshop is not well controlled, which may easily cause product microbial contamination.
