1. Non-thermal Food Preservation/Sterilization Process
2. Additive FREE
3. HPP retains Food quality, Extend shelf life!
High Pre ssur e Processing Food Preservation Machine
² Introduction
Recently consumers increasingly demand convenience foods of the highest quality in terms of natural flavour and
taste, and which are free from additives and preservatives. This demand has triggered the need for the development
of a number of non-thermal approaches to food processing.
High Pressure Processing (HPP) is a method of food processing where food is subjected to pressures 600Mpa,
without the addition of heat, to achieve microbial inactivation or to alter the food attributes in order to achieve
consumer-desired qualities. Pressure inactivates most vegetative bacteria at pressures above 600Mpa. Compared
to thermal processing, HPP results in foods with fresher taste, and better appearance, texture and nutrition. HPP
retains food quality, maintains natural freshness, and extends microbiological shelf life.
² What HPP can accomplish:
§ Inactivate foodborne pathogens
§ Inactivate spoilage organisms
§ Activate or inactivate enzymes
§ Germinate or inactivate some bacterial spores
§ Marinate meats
§ Shuck oysters
§ Extend shelf life
§ Reduce the potential for foodborne illness
§ Pressure-shift freezing or thawing
§ Promote ripening of cheeses
§ Minimize oxidative browning
Pressure Effects on Yeast
(Left: Before Processing Right: After Processing at 600 MPa and 20°C for 10 min.)
² HPP applications
§ Abalone
§ Apple Cider
§ Apple Juice
§ Apple Sauce (single serving packs)
§ Avocado (halves, pulp)
§ Beef
§ Chicken
§ Cod (both dried and salted)
§ Fruit Purees
§ Fruit Smoothies
§ Guacamole
§ Jams/Jellies
§ Limeade
§ Mussels
§ Onions (chopped)
§ Orange Juice
§ Oysters (shucked, in-shell, and shooters)
§ Prosciutto Ham
§ Ready-to-eat Meal Kits (beef and chicken)
§ Salsa
§ Seafood Salads
§ Strawberry Juice
² Main body of HPP Machine
A. Pressure vessel, framework, pressurizer
B. Hydraulic system
C. Fluid complementing system
D. Control system
² A typical processing cycle:
1. Packaged food items are placed in the pressure vessel.
2. Vessel is sealed and filled with water.
3. A pump (with intensifier) forces more water into the vessel, creating hydrostatic pressure. Pressure is
isostatically transmitted by the fluid medium. A small temperature increase (~ 3°C per 100 MPa applied)
may occur in the product, depending on the product composition.
4. Vessel pressure is maintained for a predetermined period of time (usually between 30 seconds and 15
minutes), during which time pathogens and spoilage bacteria are inactivated.
5. When the cycle is complete, the vessel is quickly depressurized, and temperatures return to the starting
temperature. Vessel is opened and product is removed.

² Our Commitment
More Security
High-pressure chamber, rack, yoke frame made by 65mm steel wire winding structure, all the high pressure
components include the internal structural, Insure absolute safe protection.
High Reliability
Our CIP divide the work media and dynamic media by piston so as to availably prevent work media enter
into pressurization system, also use filter, could filter out the impurities within the working medium, provide a
clear working environment.
Convenient Operation
PLC control system, with operator interface, could display accurate and detailed data. Pressure Boost
speed, dwell time, pressure value, pressure unloading speed are adjustable, also can save print all your
operation date for reference.
Low Maintenance
we use the combination of sealing technology, seal replacement is very simple, without professional
completion of 15 minutes to replace.
High cost performance and customer’s satisfaction
SSYH has been focused on every detail of high pressure technology. In technology research, development
and application, customer need has been fully taken into account. Our products CIP, WIP, DIP, HPP and
Ultra-high pressure valves have already brought richly returns for users in domestic and abroad, covers
Cemented Carbides, Ceramic industries, Refractories, Medical Instruments, electronic filed, food, Scientific
Research and etc.
