The twin-screw feed extruder is mainly composed of a barrel and a rotating extrusion twin screw inside the barrel. When the equipment is running, the material enters the material chamber through the feeding port, and the screw rotates and extrudes forward to transport it. Under the action of thrust, friction, shear force and heat, a high pressure and high temperature difference is formed inside and outside the chamber. The moment the material is extruded, it expands instantly due to the pressure difference.

Before production, a comprehensive inspection must be conducted.

The quality of feed will eventually affect the market and survival of a feed company. Each company should do a good job in feed quality control.

Because blood meal has high nutritional value and its processing technology and methods are becoming increasingly perfect, its application in pet feed has also received widespread attention. Some pet feed formulas will contain ingredients such as chicken blood meal and hydrolyzed blood meal.

According to relevant data, dry food accounts for the majority of the current pet market and is gradually expanding. For example, the market share of dry dog food in the UK is about 33%, 34%, 75% in Spain and the Netherlands, 50% in France and Italy, and about 76% in the United States. Our country does not have specific statistics, but judging from surveys in the pet market , about 80% of the products sold are Qianxing food. This is determined by the characteristics of Qianxing food that is easy to prepare, process and store. Among current dry foods, the vast majority are processed through puffing technology.

Single screw extruder is suitable for all kinds of fried puffed food, extruded food, nutritious rice, etc. The barrel adopts two-way temperature control of heating and water cooling, and the screw can be cooled with water. The temperature is stable and the product quality is high.
