Production Lines

Dry kibble line

Best for scalable dog and cat food supply with strong formulation and coating control.

Key equipment

Grinding, batching, mixer, conditioner, extruder, dryer, coater, cooler, packing.

Freeze dried line

Best for premium treats and high-value protein products with strict cold-chain planning.

Key equipment

Preparation, freezing, freeze dryer, metal detection, weighing, nitrogen or sealed packing.

Treats line

Best for brand differentiation, OEM orders, and lower-volume product variety.

Key equipment

Mixer, forming or extrusion, oven/dryer, cooling, cutting, packing.

Buyer Profile

Pet food brands, feed manufacturers, ingredient groups, and OEM operators building dry kibble or treats capacity.

Planning Basis

Planned after formula range, kibble or treat route, output target, automation, utilities, packaging, and factory layout are confirmed.

Starter scope: one extrusion or treats route, limited SKU count, basic QC records, and semi-automatic packing.
OEM-capable scope: formula flexibility, coating control, multiple pack sizes, retention samples, and stronger QC workflow.
Export-scale scope: higher throughput, automatic batching, warehouse zoning, traceability records, and export documentation workflow.

Capacity Reference

Reference base: Xinji Pet Food operates 40,000T annual capacity; new plant output is sized by product route.

Typical Market Regions

Southeast Asia, Middle East, Latin America, Europe

Equipment System

Core equipment package

Hammer mill

Reduces grains and protein ingredients to the particle range required for stable mixing and extrusion.

Ribbon or paddle mixer

Builds a uniform dry mix before conditioning, with mixer type selected around batch size and formula variation.

Twin-screw extruder

Controls cooking, shaping, expansion, and density across different kibble formulas and die sizes.

Dryer

Removes moisture evenly after extrusion while protecting throughput, kibble structure, and shelf stability.

Coating drum

Applies fats, palatants, or functional coatings at a controlled ratio after drying.

Cooling conveyor

Brings coated product close to ambient temperature before storage or packing to reduce condensation risk.

Multi-head packing line

Weighs and seals finished kibble into the required retail or bulk formats with changeover planning.

Layout and Market Logic

System planning changes with utilities, materials, QC, and export route

Layout Zones

Packing and finished goods

Utility Requirements

Electric power
Steam or thermal oil
Compressed air
Water and drainage
Odor and dust management

Market Planning Notes

Hot and humid markets need stronger moisture control, drying reserve, packaging barrier selection, and warehouse ventilation.
Import-oriented projects need label, COA, packing list, batch record, and shelf-life documentation prepared from the start.
Private-label factories should reserve process flexibility for several formulas, kibble sizes, and pack formats instead of one fixed SKU.

Factory Layout Discussion

Request a layout planning model for your target capacity.

A project layout should be prepared after country, material, capacity, building size, utility, and land constraints are confirmed.
