The extruder is subjected to heat and shear to optimise the starch conversion according to the quality profile of the final product. Processing temperatures are precisely regulated through individual heating and cooling systems in each section of the extruder barrel. Expansion takes place when the water in the extruder flashes off as the product is forced through the mould.

Pet food machine is used for processing like dogs and cats (pet food), birds, and piglets, frogs, sinking and floating aquatic feeds for fish. Which is high and new technical program as to catch the developing pet food market. Pet food line mainly use maize, fish meal, meat meal and some food additives as main raw material, through mixing, extruding, roasting, flavoring to get the final puffed pet food.

twin screw extruder is mainly composed of six parts: extrusion system, electric control system, temperature control system, transmission system, feeding system, and shaping system; It can also be equipped with a vapor conditioning system for wet puffed production as needed. By designing different structures and slenderness ratios according to product needs, screw extrusion systems can meet different process requirements. In actual production, only the production parameters need to be set, and various systems automatically work together, with strong stability and reliable quality.

XINHUA twin screw extruders process over 40% of the extruded fish and shrimp feed marketed worldwide XINHUA systems produce high energy feed, achieving a delicate balance of proteins, oils and carbohydrates, processed for total digestibility with no waste. It’s the right formula for high quality products that “turn feed into flesh.”

The main raw materials are corn flour, corn starch, rice flour and other starches, which are extruded and expanded into triangular, circular, square, animal and other shapes, and then baked and seasoned. Its taste is crisp, nutritious, and easy to digest.

Health, leisure and entertainment are the basic meanings of chewing snacks products for pets. SHANDONG XINHUA. focuses on the research and development and manufacture of pet food processing equipment, with different processes and different mechanical configurations to ensure meeting wider customer needs.

The raw materials are mainly starch, edible glue and oil: screw extrusion, forming and cutting, and air-drying process. Generally, high-temperature extrusion for sterilize the raw materials, then formed by a single-screw extruder, cutting after cooling, and drying finally. This is a typical example of conventional intensive production. The process is simple and the operation is convenient. The products to be various types and tastes, and various nutritional elements can be added during production to supplement the nutrition and health of the food. At present, it is favored by regular customers.

Extrusion is one of the most important new processes in modern food technology; its application has increased in the last two decades. Extrusion is an advantageous, cleaner, and more efficient technology that can produce the same or even better products than those of traditional technologies. The process has been used to produce a wide variety of foods, including snack food, breakfast cereals, and other ready-to-eat textured foods.

The pet food production line uses high-expansion corn flour grains as the basic raw material, supplemented by bone meal, meat, protein, vitamins, fiber, and other nutrients, and cooperates with a screw extruder to produce pet dog food of different shapes through a strong extrusion and instantaneous expansion molding.

Proper use of puffed extruder in work is essential to ensure safety and the longevity of puffed extruder
