Pilot size freeze dryer

Our smallest system, the TSS-023, or "Big Baby 2.0," is a great system for small production freeze drying, or as a test platform for new products.

23 tray capacity is just enough for prototyping, testing, or small batches. You can load up to 175lb of frozen product per batch, depending on loading density.

Let's be clear, this is no scaled up home appliance grade freeze dryer, this is a truly industrial grade freeze dryer that will run fast, dry 175lb of meat in 20 hours, and deliver that kind of performance day after day for years. Yes, this grade of equipment has a higher capital cost, but it makes up for it in just a few months with the level of productivity you get out of it.

Example: This machine can dry 75 lb of Skittles in under 2 hours, whereas Harvest Right or equivalent machines take up to 3.5 hours. You can run this machine 24 x 7 to dry 20,000 lbs/month and make a half million bucks per year on Skittles.

You don't pay for this machine, the machine pays for itself plus a great deal of profit.

We have ties with equipment finance companies who can approve you in hours, your payment is likely to be about $2800/month. Your profits could be upwards of $40,000 per month.

Current price of this turn key machine is $135,000
