The global market size and growth drivers:

The global macaroni market is experiencing steady expansion, with a market size reaching hundreds of billions of dollars by 2024, expected to surpass $20 billion by 2025, maintaining a compound annual growth rate of approximately 3.5%. This growth is primarily driven by three core factors: first, the continuous global population growth (projected to reach 7.8 billion by 2025) provides a large consumer base, especially in emerging markets where accelerated urbanization drives a surge in demand for convenient foods; second, the trend towards healthy eating significantly reshapes product structures, with deand for low-fat, whole grain, and organic macaroni growing at a rate of up to 10%, such as Annie's company's eco-friendly macaroni produced through renewable agricultural technology that sequesters carbon in the soil, meeting both health and environmental needs; finally, technological upgrades in the food industry (such as the widespread adoption of fully automated production lines) boost capacity and efficiency, further reducing production costs and expanding market supply.

Regional layout and competitive landscape

The global pasta production landscape is characterized by a multipolar competitive structure: Europe, as a traditional consumption center, accounts for nearly 50% of global consumption. Italy, leveraging its origin advantages and technological heritage such as bronze die techniques, produces over one-third of the world's pasta, with its premium products commanding significant price premiums (about 30%) in international markets. China has become the world's largest producer with an annual output exceeding 5 million tons, exporting over 1 million tons primarily to Asian, African, and European markets. Chinese companies' competitiveness stems from automated capacity expansion and technology localization, such as Shandong enterprises adopting vacuum extruders to boost energy efficiency by 20%, leading to a high ranking in global export equipment numbers. Russia, capitalizing on its resource and geographic advantages, is rapidly expanding its market in China. In the first two months of 2025, pasta exports to China reached 380 tons, marking a 100% year-on-year increase, highlighting its emerging position in Sino-Russian agricultural trade.

Process of pasta production line

The industrial production of macaroni is a precise integration of food engineering and mechanical automation, encompassing five major stages: raw material processing, mixing and maturation, vacuum extrusion molding, segmented drying, and packaging. Each stage's process control directly determines the final product's taste, appearance, and shelf life. The following sections will break down the core steps layer by layer, with a focus on the innovative breakthroughs in vacuum extrusion and drying technology.

Raw Material Pre-treatment: Quality Foundation Production begins with the meticulous processing of hard durum wheat flour (protein content ≥ 14%). The raw material is filtered through three layers of vibrating screens to remove impurities, then placed in a temperature and humidity controlled warehouse (temperature 25℃ ± 2℃, humidity 60%) for 24 hours to ensure even moisture penetration. During this stage, it is crucial to strictly control microbial indicators (total colony count < 1000 CFU/g) to prevent subsequent fermentation from affecting the dough's extensibility.

High-speed water-flour mixing and maturation: gluten network construction. Flour and pure water (water temperature 30℃ ± 1℃) are mixed at a golden ratio of 100:28 into a dual-axis spiral mixer. Within 90 seconds, uniform mixing is achieved under high-speed shearing at 200 rpm. The mixed dough is then transferred to a maturation chamber, where it rests for 20 minutes under low-speed stirring (10 rpm), allowing gliadin and glutenin to fully hydrate and form a dense gluten network—this is the molecular basis for the chewy texture of pasta.

Vacuum extrusion molding: The core of process innovation (key step) the matured dough is conveyed through a sealed pipeline to the vacuum extrusion system, which is crucial for breaking traditional quality bottlenecks: 

1.Vacuumde-gassing: The dough enters a closed chamber where the vacuum pump reduces pressure to -0.08 mpa, forcing air dissolved in water to precipitate out, eliminating microbubbles in the dough. Experiments show that vacuum treatment increases dough density by 12%, with a homogeneous honeycomb microstructure (verified by electron microscopy). 

2.Dual screw synergistic extrusion: The de-gassed dough is pushed by dual screws (with a length-to-diameter ratio of 12:1) through three temperature-controlled zones (38°c → 45°c → 50°c), gradually increasing in temperature. The intermeshing shear force of the screws aligns gluten linearly while partially gelatinizing starch, forming a semi-transparent gel state. 

3. Precise mold shaping: High-temperature and high-pressure dough passes through italian bronze molds (hole diameter 0.8-1.2mm), where the micro-porous structure on the mold's inner wall creates a coarse texture on the pasta surface, enhancing sauce adhesion by 50%. Comparative tests show that products from stainless steel molds have a much smoother surface (ra value 0.8μm) compared to bronze molds (ra value 3.5μm), with the latter retaining 1.2 times more sauce after cooking. Technical advantages summary: Vacuum extrusion reduces post-cooking breakage rate to less than 2% (15% in traditional methods), extends cooking time to 12 minutes (an increase of 40%), and reduces drying energy consumption by 18% due to bubble elimination.

Segmented drying: The art of balancing energy efficiency and texture (Key steps) Wet pasta extruded with 31% moisture content must undergo three drying stages to reduce moisture to 12.5%, preventing mold growth and setting the shape: 1. Pre-drying (vibrating fluidized bed): The wet pasta is spread into a thin layer on a low-frequency vibrating screen (amplitude 5mm, frequency 20Hz). Hot air at 40°C and 70% humidity passes through the material from bottom to top, reducing moisture to 25% within 30 minutes. This stage uses an air-source heat pump to recover residual heat, saving 30% energy compared to electric heating. 2. Main drying (tunnel temperature stratification control): The pasta enters a four-zone tunnel where temperature and humidity are precisely adjusted in gradients: - Shaping zone (45°C, 60% humidity): Slowly releases surface stress to prevent cracking; - Rapid dehydration zone (65°C, 40% humidity): Core moisture diffusion period; - Equilibration zone (58°C, 50% humidity): Balances internal and external moisture; - Cooling zone (40°C, 55% humidity): Stabilizes microstructure. The entire process takes 4-5 hours, with temperature fluctuations controlled within ±1°C to avoid the 'hard shell effect' (surface hardening that impedes internal water evaporation). 3. Final drying (counterflow cooling): The pasta contacts 25°C dry cold air in reverse flow, achieving the final moisture level while lowering the core temperature to room temperature, preventing condensation after packaging.

The dried pasta enters an automatic packaging line. It is packaged with nitrogen displacement (extending shelf life to 24 months, with each bag's weight controlled within ±1 gram).

Summary of craftsmanship value

The synergy between vacuum extrusion and intelligent drying technology addresses three major pain points in traditional pasta productionline:

1.Texture defects (bubbles causing easy gelatinization) → Vacuum degassing enhances chewiness by removing air pockets, resulting in a more uniform and robust texture;

2.High energy consumption (drying accounts for 60% of total energy usage) → Segmented temperature control combined with heat recovery systems saves up to 30% energy, optimizing the drying process and reducing overall operational costs;

3.Quality control fluctuations (high manual intervention) → Full-process automation with parameter closed-loop control minimizes human error, ensuring consistent quality and precision throughout production.

This technological system not only ensures high-quality output but also transforms pasta production from 'experience-driven' to 'data-driven,' setting a new benchmark for sustainable industry development by leveraging advanced analytics and real-time monitoring.

Process principles and quality improvement

Vacuum degassing eliminates microbubbles. The vacuum extruder operates at -0.08 MPa negative pressure, forcing dissolved air out of the dough, increasing its density by 12% and forming a homogeneous honeycomb structure. This process thoroughly removes microbubbles, solving the problem of residual bubbles causing post-cooking gelatinization in traditional methods, reducing breakage rates from 15% to less than 2%, and extending cooking time by 40% (up to 12 minutes). 

The vacuum environment promotes full hydration of gliadin and glutenin in durum wheat flour (protein ≥ 14%) within 20 seconds, forming a dense gluten network. Electron microscopy scans show that after vacuum treatment, gluten fibers are more orderly arranged, giving pasta elasticity and chewiness, with hardness increasing by 25% (texture analyzer data). 

In combination with bronze molds (surface roughness Ra value of 3.5 μm), vacuum extrusion creates a micro-porous structure on the pasta surface, improving sauce adhesion by 50%, significantly better than the smooth surface of stainless steel molds (Ra value of 0.8 μm).

Energy consumption and efficiency optimization

1.Energy-saving design reduces overall costs. 

Variable frequency drive system: the main motor (7.5 kW) and vacuum pump (2.2 kW) adjust power according to demand, saving 20% energy compared to atmospheric equipment. 

Innovative thermal management: three-stage temperature control zones (38°C → 45°C → 50°C) during the extrusion process reduce heat loss.

2.Continuous production significantly improves efficiency. 

The twin-screw co-extrusion (with a length-to-diameter ratio of 12:1) integrates 'feeding-mixing-extruding' into one process, eliminating the start-stop losses associated with traditional batch production.

Comparison of Performance with Traditional Equipment

Application Expansion and Technological Prospects: 

1. Adaptability to Special Ingredients

The vacuum extruder can handle diverse raw materials such as whole grain flour, gluten-free rice flour, and high-protein bean powder. For instance, golden pea protein powder (purity > 80%) can still form a stable dough under vacuum conditions, solving the problem of shaping low-gluten ingredients.

2.Smart upgrade direction

Online quality control system - integrates near-infrared spectrometer (NIRS) for real-time monitoring of dough moisture and protein content, with fluctuation control less than 0.5%. 

Predictive maintenance module - reduces downtime losses through bearing wear monitoring (such as carbon nanopolymer repair technology).
