Freeze Drying Machinery

FD1000 Industrial Freeze Dryer

The FD1000 is an industrial freeze dryer with a 1,000kg ice capacity, 103m² shelf area and doors at both ends. This freeze drying machinery is ideal for large scale, commercial freeze drying applications, such as food processing.

FD1000 Specification Summary

Turn-Key Service: Unless otherwise specified, Cuddon freeze drying machinery sales include CIF freight to your nearest international seaport, installation/commissioning/staff-training by Cuddon engineers, and a full 12-month warranty.
Capacity and Cycle Time: Cuddon Freeze Dry's quality acceptance test is to sublimate and condense the vapour condenser capacity of ice within 24 hours. For the FD1000 this equates to 1000kg of ice.
Construction Material: Chamber, doors, hinges, shelf modules, trays and vapour condenser constructed from AISI 304 stainless steel.
Chamber: Shelf modules (x4) and vapour condenser are contained inside chamber. FD1000 has a door at both ends, allowing wet and dry room application.; Two viewing ports, each 180mm in diameter, are provided in the doors, allowing observation of both the vapour condenser and product trays during the drying cycle.; Chamber is fitted with stainless steel pneumatically operated valves that isolate the vacuum line connection, drain, water defrost and vacuum release.
Modular Shelf Heating Plates: Plates fabricated from T304 stainless steel with 2B finish. FD1000 contains 4 x shelf modules, each with 16 heat plates (shelves).; Each shelf module is removable from the chamber for maintenance or cleaning, and is done by rolling onto a trolley which is provided.
Trays: Two sets of T304 stainless steel trays are provided as standard. Tray trolleys are optional.
Heating System: Thyristor controlled electric boiler, connected in series with the heat plates. Heating fluid is glycol based and is circulated by a centrifugal pump, allowing heated or cooled fluid to be circulated through the plates on demand of the electronic load controller. A cooling heat exchanger is provided in the circuit for reducing the temperature of the plates.
Vacuum System: Roots blower and backing pump are connected to the chamber by heavy duty PVC lines and pneumatic isolating valve. Pump exhaust is vented to the exterior of the building housing the freeze dryer.
Refrigeration: Refrigeration condensing unit is purpose-built with capacity control to allow economical use of the low-temperature R507 refrigerant. Includes water cooled condenser.
Vapour Condenser: T304 stainless steel tube in parallel circuits to form a direct expansion refrigerated coil.; Defrosting ice after a product cycle is by water. Hot water defrost optional using heat recovery from the refrigeration system.
Low Temperature Option: A lower temperature option can be quoted if required, giving –55°C vapour condenser temperature, and –35°C/+70°C shelf freezing/heating.
Control System: OMRON PLC interfaced with OMRON touchscreen control panel. Screen includes graphic overview of freeze drying system. Automated system will ramp/reduce energy to govern sublimation pressure to pre-set parameters.; 15 x 15-step recipe programming capacity, 250 batch storage, software for data retrieval and analysis. In-built modem allows remote access for monitoring and service.
