1. Core Process Advantages
Different from traditional high-temperature extrusion technology (extrusion above 120℃), this production line adopts low-temperature processing throughout the whole process to retain the original nutrition and natural flavor of raw materials to the maximum extent. The core process highlights are as follows:
Low-temperature cold pressing forming to retain raw material activity
Pellet forming is completed by low-pressure cold pressing under normal temperature without high-temperature screw extrusion. It will not destroy the molecular structure of active nutrients such as meat protein, vitamins and probiotics, guaranteeing the nutritional quality of products from the forming stage.

Three-stage gradient baking for uniform and stable curing
Adopting multi-layer mesh belt baking oven with independent temperature control in three zones: short-time high-temperature shaping in the early stage, constant-temperature uniform curing in the middle stage, low-temperature flavor enhancement and freshness locking in the later stage. The baking temperature is precisely controlled within 70–110℃ to ensure consistent curing degree inside and outside pellets without undercooking or scorching. The moisture content of finished products can be controlled stably.
