FAQs About High Pressure Processing (HPP) Equipment

Q1: What’s HPP technology?

High Pressure Processing (HPP) exposes food to high pressure via a water medium for several minutes at low or room temperature, effectively killing bacteria, viruses, yeast, and mold.

Q2: What are the benefits of HPP technology?

HPP is globally recognized as an antimicrobial process that inactivates pathogens and slows spoilage bacteria, extending refrigerated shelf life 2–10 times. It preserves nutrients and bioactive compounds, maintaining vitamins and natural quality. This technology allows manufacturers to reduce chemical preservatives and lower food safety testing frequency.

Q3: In which fields can HPP technology be applied?

Applicable across multiple food processing scenarios, including juices and beverages, meat products, pet food, seafood, infant formula, dairy, as well as cosmetics and pharmaceuticals.

Q4: What is the difference between HPP technology and traditional sterilization methods?

Traditional sterilization methods (e.g., thermal processing) may damage nutrients and flavor, while high-pressure sterilization is performed at low temperatures, better preserving product quality, enhancing taste, and retaining natural nutrition that heat treatment cannot achieve.

Q5: How do we differ from other HPP equipment manufacturers?

We are more than an equipment supplier — we are a strategic partner. We actively support our clients’ R&D processes with full lifecycle services, working alongside them to solve technical challenges and drive product performance and industrialization breakthroughs.

Q6: Does HPP processing destroy nutrients in food?

No. HPP technology only disrupts the non-covalent bonds of microorganisms without damaging the nutritional molecules in food, such as vitamins and proteins. It preserves the original nutrients and active ingredients of products, with a retention rate of over 90%. This makes HPP particularly suitable for products with high nutritional preservation requirements, including baby food, probiotics, and health supplements.

Q7: How much can HPP extend food shelf life?

Under refrigerated conditions (0–4°C), the shelf-life extension varies depending on the type of food product. HiLock provides customized testing services to evaluate the optimal HPP processing parameters and expected shelf-life improvement for your specific products.

Q8: What is the processing capacity of HPP equipment? Can it meet large-scale production requirements?

Yes. HiLock HPP equipment is designed to meet the needs of high-volume commercial production. Industrial models can process up to 3,000 liters per hour and support 24/7 continuous operation.

The product portfolio covers laboratory, pilot-scale, and industrial production models, providing flexible solutions for small and medium-sized manufacturers as well as large enterprises. Production capacity can be customized according to different application requirements.

Q9: Does HPP equipment require a large installation space?

No. HiLock HPP equipment features a compact structure and optimized design, requiring less installation space compared with traditional industrial processing systems. The exact dimensions depend on the specific equipment model and configuration.

Q10: What packaging materials are compatible with HPP processing?

HPP technology is suitable for a wide range of flexible and semi-rigid packaging formats, including:

• Vacuum bags
• Aluminum foil bags
• PET bottles
• Glass bottles

The packaging must be able to withstand high-pressure compression and recovery during processing. HiLock provides professional guidance on packaging compatibility to ensure stable HPP processing performance.

FAQs About Warm Isostatic Pressing (WIP) Equipment

Q1: What is WIP technology?

Warm Isostatic Pressing (WIP) is a compaction process that densifies the material to increase its strength, durability and properties.

Q2: What are the key technical advantages of HiLock WIP equipment?

Industry-leading technology achieves 600 MPa ultra-high pressure + 150°C high temperature (vs. 140°C industry average). Equipped with proprietary high-pressure technology and a precise pressure-temperature coordination system for uniform and accurate control.

Q3: What capacities and applications does HiLock WIP support?

From lab-scale R&D to GWh-level production, HiLock WIP serves advanced ceramics, powder metallurgy, electronic ceramics, new energy materials, and solid-state batteries, enabling densification, defect removal, interface enhancement, and improved material performance.

Q4: What makes HiLock different from other high-pressure equipment manufacturers?

HiLock provides more than equipment — we deliver full-chain technology and process solutions.

• Self-developed core components: Patented S600 intensifier with independent control of key technologies and international-level performance.
• Full-process support: From R&D to mass production, offering process consulting, joint development, and industrialization support.
• Flexible manufacturing capability: Supported by a 100,000 m² precision manufacturing platform for scalable delivery and customized solutions.

Q5: What is the fundamental difference between WIP and traditional mechanical rolling in solid-state battery production?

Traditional rolling applies only unidirectional pressure, causing layer slippage and uneven density. WIP uses a fluid medium (oil/gas) to apply 360° uniform pressure, enabling conformal contact between layers, achieving over 95% density and reducing porosity below 0.15%, significantly lowering interface resistance and improving cycle stability.
