With the rapid development of pre‑cooked dishes, frozen food, meat products and vegetarian‑food industries, the demand for cost‑effective plant‑protein raw materials keeps growing. Textured protein and fibrous protein boast advantages such as low fat, high protein, high meat‑simulation degree and authentic taste. They are core raw materials for meat substitution and cost reduction in the food industry. JINAN RUN MACHINERY CO., LTD manufactures fully‑automatic production lines for textured protein and fibrous protein. Featuring proven processes, high automation and stable operation, the equipment enables large‑scale and standardized production of plant‑based protein, and stands as the preferred choice for food enterprises to expand production capacity and develop meat‑analogue product ranges.

This production line mainly adopts low‑temperature soybean meal and peanut meal as raw materials, which are easily accessible with low production costs. Adopting twin‑screw extrusion‑puffing and curing technology, the equipment processes powdery raw materials into plant‑protein products with natural lean‑meat fiber structure through high‑temperature and high‑pressure physical reorganization. The finished products deliver distinct texture, excellent fiber‑drawing effect, strong chewiness, favorable water absorption and fast flavor absorption. With stable product quality, they meet standards for deep‑processed food.

Textured protein and fibrous protein produced by this equipment have a wide range of applications. They can be used for ham, sausages, canned meat, fast‑food prepared meals, frozen food, pre‑cooked dishes, vegetarian‑meat snacks and many other products. They can serve as fillers for meat products to cut raw‑material costs and improve mouthfeel, or be used independently as vegetarian raw materials. Realizing multi‑purpose application of one machine, the equipment helps enterprises diversify product portfolios and enhance market competitiveness.

I. Core Production Process of the Equipment

The whole production line features compact layout and smooth process connection. It realizes fully‑automatic continuous production with low labor input and high production efficiency. The complete production workflow (from right to left) is shown below:

Raw‑material mixing by powder mixer → automatic feeding via screw elevator → curing and forming by twin‑screw extruder main unit → shaping and sizing by multi‑function shaper → conveying and heat dissipation by air conveyor → constant‑temperature drying and dehydration in oven → finished‑product cooling and discharging by cooling conveyor

The equipment adopts purely physical curing technology without extra additives, so as to retain plant‑protein nutrition to the maximum extent. The whole‑process closed‑loop operation effectively prevents material contamination and product specification deviation. The finished products have uniform color, plump fibers, good boiling resistance and stable quality, complying with food‑safety production specifications.

II. Core Advantages of the Equipment

Equipped with an upgraded twin‑screw extruder main unit, the production line is wear‑resistant, durable and stable in extrusion performance, which ensures sufficient raw‑material curing and uniform fiber formation. Matched with multi‑function shaping equipment, it allows flexible adjustment of fiber density and forming state, and one‑click switching among multiple product specifications. With automatic control, simple operation, low energy consumption and high stability, the whole machine adapts to continuous mass production for small‑, medium‑ and large‑sized factories. It delivers high universality, low investment cost and outstanding cost‑performance.

III. One‑stop Comprehensive After‑sales Service Support

Our company provides one‑stop supporting services to guarantee smooth commissioning and stable operation for customers:

‑Process and Formula Support: Proven basic formulas for plant‑protein production are provided to help customers finish commissioning rapidly, eliminating formula‑development costs and trial‑and‑error cycles.

‑On‑site Installation and Commissioning: Professional technicians carry out on‑site equipment installation, circuit connection and overall commissioning to ensure stable production once the equipment is delivered to the plant.

‑Professional Technical Training: Professional technicians can provide on‑site one‑on‑one hands‑on training for plant operators, covering equipment operation, parameter adjustment, daily maintenance and basic troubleshooting, so that operators can master independent and proficient operation of the equipment.

‑Reliable Warranty Service: The complete set of equipment enjoys a one‑year warranty. Free repair and spare‑part replacement are available for non‑man‑made damage within the warranty period. After warranty expiration, genuine spare parts will be continuously supplied at favorable prices to safeguard customers’ production.

IV. Application Scenarios

This equipment is widely applicable to meat‑product factories, vegetarian‑food processing plants, frozen pre‑cooked‑dish manufacturers and deep‑food‑processing enterprises. It serves as an efficient production device for replacing fresh‑meat raw materials, optimizing product formulas, lowering production costs and developing new plant‑protein product categories, bringing high return on investment.
