The components of pet feed and fish feed puffing machines mainly include the following parts:

Feeding system: composed of a feeding hopper and a feeding screw, the feeding screw sends the feed into the expansion chamber

Puffing chamber: This is the core part of the puffing machine, consisting of the puffing chamber body, heating screw, and puffing chamber cover. The interior of the puffing chamber is a sealed space with a certain pressure, where the feed is heated and expanded to form puffing. The heating screw is responsible for heating the feed inside the expansion chamber, and there is a pressure regulating valve on the expansion chamber cover to adjust the pressure inside the expansion chamber

Degassing system: composed of degassing holes and degassing valves, used to remove gas from the expansion chamber

Discharge system: consisting of a discharge port and a discharge screw, it discharges the expanded feed from the expansion chamber

The working principle of pet feed and fish feed puffing machine:

The working principle of a puffing machine is to heat the feed to a certain temperature and pressure, causing the water to expand and evaporate. The feed expands instantly, forming porous spherical particles. During the expansion process, starch molecules undergo gelatinization, and high temperature and high pressure can destroy the anti nutritional substances and cell walls in the feed, improving the digestibility and nutritional value of the feed

Application scenarios of pet feed and fish feed puffing machines:

Pet food production line: used for producing various pet foods, such as cat food, dog food, etc
Aquatic feed production line: used for producing fish feed, especially floating fish feed, suitable for aquaculture needs

These components and working principles make pet feed and fish feed puffing machines play an important role in animal feed processing, enabling efficient production of high-quality feed products.
