Small experimental screw extruder pet food molding equipment

1、 Equipment working principle

The core working principle of this device is based on the conveying, compression, melting, and shearing effects of screws. When working, the evenly mixed powdered raw materials are fed into the hopper and pushed forward by a rotating screw. Under the heating of the sleeve and the strong mechanical shear of the screw, the raw materials gradually gelatinize and melt, forming a uniform dough like material. At the extrusion end, the material is forced to pass through a die with a specific shape, instantly releasing pressure and shaping, and then cut into particles of predetermined length by a cutting knife, ultimately forming the desired pet food form.

2、 Equipment advantages

1. Flexible and efficientThe device is compact in size and suitable for laboratory environments. It can quickly complete the entire process from feeding to finished products, greatly shortening the R&D cycle and allowing researchers to conduct multiple formula and process parameter tests in a short period of time.

2. Accurate and controllable parametersUsers can accurately and independently control key parameters such as screw speed, temperature in each section, feeding speed, and mold pressure. This high degree of controllability makes it possible to study the effects of different process conditions on product texture, nutrient retention, and digestibility.

3. material-savingA single experiment only requires a small amount of raw materials (usually in kilograms), effectively reducing the material cost of new product development, making it particularly suitable for testing expensive or scarce functional raw materials.

4. multi-purpose machineBy replacing different molds and adjusting process parameters, the same equipment can produce pet food with different shapes, sizes, and densities, meeting diverse research and development needs.

3、 Applicable raw materials

This device has good adaptability to various common pet food ingredients, including but not limited to:

• Grain starch: Corn flour, wheat flour, big Rice noodles, potato starch, etc., as the basis for providing energy and expanding structure.

• ProteinChicken meal, fish meal, soybean meal, gluten meal, etc. are the core components of protein nutrition in pet food.

• Dietary fiberWheat bran, beet meal, fruit and vegetable fiber, etc. are used to regulate the fiber content and intestinal health function of food.

4、 Production product type

By adjusting the process, this equipment can mainly produce two types of products:

• Puffed pet foodBy using high temperature and high pressure to vaporize the moisture of the material instantly during extrusion at the die head, a porous and loose structure is formed. This is a common form of mainstream dry dog food and cat food on the market.

• Soft puffed or non puffed pet foodBy controlling temperature and moisture, produce snacks or specialty prescription foods with denser and softer texture.

5、 Applicable scenarios

• New product formula developmentTest the feasibility and palatability of new raw materials and formulas.

• Optimization of process parametersStudy the effects of temperature, pressure, moisture, etc. on the nutritional composition, texture characteristics, and shelf life of products.

• Small batch customized productionSmall scale customized production for high-quality pet markets, specific breeds, or pets with special health needs (such as hypoallergenic and prescription foods).

• Teaching and ResearchUsed for education and research in food science and animal nutrition related majors.

• Small experimental screw extruder pet food molding equipmentDirectly supplied by the manufacturer, saving 30% of costs.
