Hygiene and cleanliness of the processing environment for a small dog food pellet machine need to be planned in advance, with the core principles being "clear zoning and cleanliness/dryness." It is recommended to designate a separate processing area in the kitchen, isolated from the human food processing area, to avoid cross-contamination between pet food ingredients and human food. Before processing, thoroughly clean the work surface with a chlorine-based disinfectant (such as 84 disinfectant diluted 1:100), wipe the surface, let it sit for 10 minutes, rinse thoroughly with clean water, and allow it to dry before placing the processing tools. Simultaneously, keep the processing environment dry and well-ventilated by opening windows or turning on exhaust fans to prevent the growth of bacteria in a damp environment. Clean up clutter around the processing area to ensure ample operating space and reduce the possibility of spilled ingredients and bacterial hiding places. If there are other pets or poultry in the household, they must be kept outside the processing area to prevent hair, feces, etc., from contaminating the ingredients and dog food manufacturing equipment.

Disinfection of the processing tools for the best dog food pellet machine is a core aspect of hygiene and safety, including ingredient handling tools and puffing equipment. Tools used for processing raw materials (such as knives, cutting boards, and mixing bowls) must be dedicated to that purpose and must not be shared with tools used for processing human food. Before use, sterilize them by boiling in water for 15-20 minutes or by using a dishwasher's high-temperature sterilization mode. Tools for processing raw and cooked ingredients must be kept separate; for example, cutting boards for raw meat and vegetables must be clearly distinguished to prevent bacteria from raw meat from contaminating cooked ingredients. The pet food making machine for home must be sterilized before and after each use. Before use, wipe the outer casing, feed hopper, and other accessible parts with 75% alcohol. After use, disassemble the screw, die head, and other parts, rinse them thoroughly with warm water, wipe them with food-grade disinfectant wipes, and allow them to air dry before reassembling. Note that sterilized tools and equipment should not be touched with unsterilized hands to prevent secondary contamination.

The hygiene and cleaning of the dry dog food making machine after processing is crucial. Residual raw materials and waste in the processing area must be cleaned up promptly to prevent bacterial growth. Wipe the work surface and floor with a damp cloth to remove raw material debris and stains, then disinfect a second time with disinfectant. After cleaning and disinfecting the processing tools, store them separately in a dry and ventilated cabinet to avoid moisture. After cleaning the extruder, cover it with a clean dust cover to prevent dust from falling in. In addition, homemade pet food should be sealed and stored in a timely manner, and waste from the processing area (such as raw material scraps and washed mud and sand) should be disposed of immediately to avoid attracting mosquitoes and bacteria, ensuring hygiene and safety for the next processing.
