Continuous Pet Food Making Machinery

Jinan Sunrising has a unique capability to provide complete systems for the production of dried pet foods. Over 10 years of experience has given us unrivalled process expertise in technologies including mixing, forming and drying – the key processes in dried pet food and pet treat production.

Experience in the design and installation of many pet food lines throughout the world has given Jinan Sunrising a unique data base of knowledge. Jinan Sunrising uses its process familiarity to design equipment that meets the specific needs of the industry, and imaginatively solves issues such as better weight control, reduced maintenance and easier use.

Our pet food extrusion lines are designed to operate 24/7 and to process a wide range of recipes. Manufacturers can produce any number of textures, shapes, flavors and colors. Our goal is to provide flexible and scalable production tools to produce high-quality, tasty and nutritional pet foods.

HOW IS PET FOOD MANUFACTURED ?

Typical raw materials used in pet food processing include cereal flour, vegetable proteins, minerals and vitamins and, in some cases, meat or fish flour and fresh meat. The dry ingredients enter the  the pre-conditioner and are steam-hydrated. The counter-rotary twin shaft unit blends the ingredients and ensures proper mixing of steam, moisture and ingredients. Preconditioning produces partial gelatinization of starches and texturing of polymers. The partially cooked mixture is then fed to the twin-screw extruder. Shearing, internal temperature, pressure, moisture and residence times are accurately controlled to achieve optimum starch gelatinization without loss of food quality. Liquids or steam may be injected through ports in the extruder barrel at various processing stages. Degassing is possible at this stage using a vent-stuffer.

Granules are then shaped when they are extruded through the die. They are then put through a dryer, which reduces moisture (generally between 8 and 10%). The product is then coated, and flavoring before cooling and packaging.

Chenyang pet food production lines offer several advantages to manufacture quality products :

Precise control of process parameters and automation to ensure optimized granule quality: gelatinization, expansion, texture and consistent quality. These quality criteria can be achieved because screws ensure homogeneous processing and positive pumping. The processing of the viscous paste does not depend on the friction between the screws and the barrel. The embedded automatic temperature control and adjustment systems, the modular screw configurations and screw speeds are easily programmed and contribute to the line’s high performance.

Intelligent pet food extruder : recipe management (recording, access, supervision), process management (start/stop), installed sensors, control and maintenance. Advanced line automation contributes to lower operating costs and facilitates consistent nominal production.

Creative shapes and finishing through the use of special dies to create innovative shapes and differently-textured products.Round, heart, triangle, palm shapes etc are available.

Ingredient flexibility to process a wide range of raw materials with high fat content when needed

Reduced maintenance using standard parts for extrusion and drying equipment, easy access to different machine components.

Support services, including training, assistance and design expertise for new products

Capacity from 100kg/hr to 5tph

Double- screw Extruder

It's composed by pre-conditioner, feeding system, extruding system, heating system, driving system, cutting system and control system. The raw materials are put into barrels by feeder, after high temperature and high pressure in the barrels, and then extruded through the mould; the raw material is expanded to expected shape.

Steam Dryer

The dryer is reciprocating structure, it contains transmission electrical motor, stainless steel carrying belt, infrared heating pipes and supporting frame. As dog foods go through the dryer, they will be dried quickly in a clean condition. In the all production line, this dryer can dry materials quickly.
