Chamber

Typical maximum usage is 190 FLA, 157 kW. Estimated cost per cycle of $252 (based on $.11 per kW hr)Parker Freeze Dry Chambers are made of heavy duty 304 beaded stainless steel. Aluminum carts and vapor condensers are contained inside the chamber. A glass view-port in the door allows observation of both the vapor condenser and carts during the drying cycle.

Control System

The Allen Bradley PLC Control System and HMI Screen include a graphic overview of the freeze drying system. It is automated to ramp or reduce heat to control sublimation to preset parameters. Full control of vacuum and refrigeration systems, and data logging allows for trend analysis and cycle development. Remote access via Ethernet allows for remote service and analysis.

Heated Carts

Heated carts are all aluminum construction for heat exchange efficiency. Each heated cart comes with 42 heated trays and 42 product pans providing radiant heat from above and conductive heat from below.

Vacuum System

The Parker 16-R exclusively has built in redundancy. Dry screw pumps achieve deep vacuum throughout the process, eliminating oil back steaming risk. In addition, dry screw pumps tend to be more quiet, and require less maintenance and repair.

Vapor Condenser Plates

Aluminum plates in parallel circuits form a direct expansion refrigerated coil. Ice is defrosted after a product cycle by recirculating hot gas. The refrigeration condensing unit is purpose-built with capacity controls to allow economical use of the low R507 refrigerant, including an air cooled condenser.

Electrical Usage

Typical maximum usage is 235 FLA, 195 kW. Estimated cost per cycle of $312 (based on $.11 per kW hr)
