High Capacity Commercial Freeze Dryer

When you need serious freeze drying capacity, the TSS-447 is our best first step.

This industrial freeze dryer outperforms every other freeze dryer per square foot of factory space. It can be easily and thoroughly cleaned and sanitized without special equipment, and it has the highest production capacity of any comparable machine.

  • Commercial freeze drying is a capital and energy intensive process, but the product that results is more than worth the costs. However, if you are going to spend the capital and energy, you should try to get the most for your money. How? By looking at all of the aspects of your facility and equipment.
  • Example 1: The total amount of footprint your dryer occupies, including the chamber, the chiller, the vacuum system, and the product handling area can vary hugely from one brand to another. Newsflash, commercial footprint is really expensive.
  • Example 2: Cleaning and sanitizing your commercial freeze dryer sounds like a remote future problem, but the first time you need to do it, and you can't remove any of the shelves and heaters, when you can't access the vapor condensers, when you have many cracks and contamination accumulation points, you will suddenly wish you had paid more attention, because it will be too late.
  • Example 3: Product handling and cycle time are two of the most limiting factors in your production capabilities, but have you considered how much time you need to spend to unload your system, load the new product, melt off the vapor condensers, and restart the next batch? Just an hour per day lost to product handling can cost a quarter million dollars per year in profits.
  • All of the shelves in this commercial freeze dryer are mounted in rolling racks that you can load while the machine is running another batch. You can prepare and store the product in those racks until it is time to start the next cycle. Then roll out the racks with dry product, melt off the vapor condensers, and roll in the racks with wet product and start.
