FREEZPHERE®

FREEZE DRYING
NATURAL CONCENTRATES AND EXTRACTS

Traditional Methods
High energy cost, approximately 40% of the product has to be reprocessed because of particle size.
High maintenance cost, because of high amount of moving parts.
Large floorspace required in facility.
Uneven particle size distribution
Cleaning Difficulty does not allow product versatility
Use of environmentally unfriendly refrigerant gases.

The Freezphere® Difference
High energy savings through avoidance of reprocesses
Low maintenance cost because small amount of moving parts.
High Use of Facility space, due to Compact Design.
Precise control of particle size.
Environment Friendly
Easy Cleaning
Possibility of integration with CIMA LN2 plant.

Pre-Freezing
Process starts from an extract or liqueur (40-50% solid content)
Concentrate is cooled (3-5°C) prior to foaming.
After cooling, concentrate enters the foaming chamber, where N2 is injected to create a foam. Nitrogen flow is thoroughly controlled in order to assure constant density of the foam.
Immediately after foaming, precrystallizing is performed, where temperature is controlled very precisely in order to obtain homogeneous coloring of the crystal.

Freezphere®
Formation/Deep Freezing
Prefrozen product is gently pumped through a vibrating nozzle, generating small droplets of uniform size, which turn to perfectly shaped freezpheres® during free fall inside the freezing chamber, obtain a high quality product with the following characteristics.

– Perfectly spherical
– Free from dusts and fines
– Highly homogenous and monodispersed particle size.

After the freezing chamber, product is placed in trays and trolleys and taken to a deep freezing chamber (-40,-45°C) prior to the freeze drying process.

Freeze Drying
Trolleys are transported through a rail system inside the freeze drying chamber, where in controlled vacuum and temperature conditions, freeze drying process (dehydration by sublimation process) takes place.
Freeze drying system has the following characteristics:
Fully automated process
Recipe Operation for product versatility
Possibility of Residual moisture in product under 5%
Fully sanitary and easy cleaning design
High effectivity in steam collection and condensation.
Heat transfer by means of heating plates, without direct contact with the product, assuring dryness uniformity.
Automated loading and unloading (optional)
Redundant systems for cooling and vacuum (optional)

Packaging
Once product has been freeze dried is transported to packing area.
Packing versatility according to market needs (single dose, bag, jar, can).
Product packaging takes place under controlled Temperature and Humidity conditions assuring product integrity.
Sanitary design for easy cleaning.
