Extruder Puffed Food-manufacture,factory,supplier from China

Principles and Advantages of Puffed FoodPuffed food, also known as extruded food, exploding food, light food, etc., is a new type of food developed internationally in recent years. It uses grains, beans, potatoes, vegetables, etc. as raw materials, and is processed by puffing equipment to produce a wide variety of food with exquisite appearance, rich nutrition, crispy and delicious food. Therefore, a large category of food has been formed uniquely.

Processing Technology of Puffed Instant Yam Powder01Mixing machine: Add nutritional additives and a certain proportion of water to the raw materials and mix them evenly.02Feeding machine: transports the mixed raw materials to the feeding hopper of the extruder.03Extruder: It is produced using the world's most advanced twin-screw extruder, which allows the starch granules to expand and refine during the puffing process of yam at high temperature, high pressure, and high shear force, and the starch molecular chains open, increasing the surface area of the food particles.

The twin-screw feed extruder is mainly composed of a barrel and a rotating extrusion twin-screw in the barrel. When the equipment is running, the material enters the material cavity through the feeding port, and the screw rotates and squeezes forward to be transported. Under the action of thrust, friction, shear force and heat, a high pressure and high temperature difference is formed inside and outside the cavity. The moment the material is extruded, Instant expansion due to pressure difference.

Advantages of Twin Screw Square Barrel ExtruderTwin-screw square barrel extruders are mainly used to produce various snacks and foods. Including puffed snacks, fried snacks, artificial rice, macaroni, etc.

IntroductionSecondary extrusion technology is a common food production process, mainly used in the production of various puffed foods, such as edible puffed potato chips, shrimp chips, squid rolls, puffed pea crisps, etc. The principle is to destroy the starch granules under high temperature and high pressure, so that the food can expand rapidly. The following is a brief introduction to the specific process of secondary extrusion.process flow1. Raw material preparation  First of all, high-quality raw materials need to be selected.

dog food extruderThe dog food can be turned into many different shapes of dog food, and can be customized with different flavors. The raw materials are formed after high temperature and high pressure treatment, which is suitable for mass production and sales. Dog food equipment can realize automated production methods and greatly improve production efficiency.

The first point: control of puffing equipmentDifferent puffing equipment vary in the degree of puffing. Generally speaking, puffing equipment can control the time, temperature and pressure of raw materials under heating and pressurization conditions, thereby affecting the puffing degree of raw materials. By adjusting the parameters of the puffing equipment, different degrees of puffing effects can be achieved.The second point: raw material ratioThe raw material ratio of puffed food also has a certain impact on the degree of puffing.

Advantages of Puffed Floating Fish Feed1. Easy feeding and management to reduce diseasesExtruded aquatic feed can be suspended on the water surface for a long time. There is no need to set up a special feeding platform when feeding, just feeding at a fixed point. Fish need to float on the water surface when feeding, so they can directly observe the feeding situation of the fish, adjust the feeding amount in time, and understand the growth and health status of the fish in a timely manner.

First of all, we take the production of aquatic feed as an example, according to the material and purpose of the expansion from the structure of the single screw extruder and twin screw extruder,In general:--- Single screw extruder: suitable for processing all kinds of raw materials and common livestock and poultry compound feed.--- Twin-screw expander: The final product requires good molding and beautiful appearance, uniform maturation and adjustable density of compound feeds (aquatic food and pet food) and high value-added raw materials (alpha starches and histones), etc.
