Meat & Poultry
Control Listeria and Salmonella in cooked and raw products, sliced or whole.
Dairy Products
Extend the shelf life of milk, yogurt and dips while keeping a fresh mouthfeel.
Seafood
Shuck oysters and inactivate Vibrio while keeping texture, flavor and yield.
Baby Food
Gentle, heat-free sterilization for purees and jars — no loss of nutrition.
Ready-to-Eat Meals
Sauces, soups and chilled meals that stay fresh longer on the shelf.
Pet Food
Clean-label, safe nutrition for dogs and cats — fresh taste, no preservatives.
R&D & Laboratory
Pilot testing, recipe development and process validation on lab-scale units.

Why HPP
Why Processors Choose HPP
High pressure processing is the fastest-growing cold pasteurization technology in the food industry. It delivers safety and shelf life without the side effects of heat.
Cold Pasteurization
Pure water pressure up to 600 MPa inactivates microorganisms without heat, so nutrition and fresh flavor survive.
Extended Shelf Life
Extend chilled shelf life by 2 to 10 times and cut waste, returns and distribution losses.
Food Safety
Effectively control Listeria, Salmonella, E. coli and Vibrio in finished packaged products.
Clean Label
No preservatives, no additives and no heat damage — support "all-natural" and "no additives" claims.
Fresh Taste & Texture
Color, aroma, vitamins and texture stay intact — products look and taste freshly made.
Proven & Scalable
Mature industrial technology with 60–500 L vessels, high throughput and low energy cost per kilogram.
How It Works
Four Steps to Cold Sterilization
Fully packaged products are treated in a water-filled vessel, inactivating microorganisms from every direction at once.
01
Load & Seal
Fill packaged products into the vessel basket and close the door.
02
Pressurize
Water is pumped to up to 600 MPa, compressing the product evenly from all sides.
03
Hold
Isostatic pressure is held for seconds to minutes, inactivating pathogens throughout the package.
04
Unload & Ship
Pressure is released and products are unloaded — ready for chilled distribution.

FAQ
Frequently Asked Questions
What is HPP and how does it sterilize food?
High pressure processing (HPP) places packaged food in a sealed vessel filled with water and applies ultra-high pressure (up to 600 MPa). The isostatic pressure inactivates pathogenic and spoilage microorganisms without heat, so the food keeps its fresh taste, color, texture and nutrients.
Which foods can be processed?
HPP suits liquid and solid products with high water content: juices and beverages, fruits and vegetables, meat and poultry, dairy, seafood, baby food, ready-to-eat meals, pet food and many others. It can be applied to most products already packaged in flexible or semi-rigid containers.
How much longer is the shelf life?
Depending on the product, packaging and cold-chain conditions, HPP typically extends chilled shelf life by 2 to 10 times. Our engineers can run trials on your product and give you validated shelf-life data.
What is the minimum order and lead time?
There is no fixed minimum order. Standard machines are produced in batches with typical lead times of 30–60 days, depending on configuration. Tell us your required capacity and we will confirm the exact delivery schedule.
Do you provide installation and training?
Yes. Each order includes on-site installation guidance and operator training. We also provide process support to help you set up pressure and hold-time parameters for your specific products.
What about warranty and spare parts?
Machines come with a standard warranty and long-term spare parts supply. Our after-sales team provides remote diagnostics and 24/7 support, with service engineers available for on-site visits.
