FDL Tray Freeze Dryer


The FDL freeze dryer/lyophilizer designed to fit commercial and industrial freeze drying process, material loading by bulk in trays, the range machines design and produce according to GMP directive.


Tray/shelf freeze dryers come with integrated structure, all its subsystem are module installed, connect and controlled by PLC based electric cabinet, so FDL freeze dryers are easy transport and install, also have a wide range option parts/functions.


Shelf freeze dryer lyophilizer install one module stainless steel shelves which fixed in drying chamber, could widely use in food, chemical or pharmaceutical industry, tray bulk loading and drying.


Typical applications:

  • Diary (Milk, yogurt, probiotics)
  • Fruit or vegetable pulp.
  • Pharmaceutical fluid,solid or mixture.
  • Other bulk loading fluid, mixture or powder products.


VIKUMER Freeze Dry could be custom design to fit your special request with cost-effective price, the range lyophilizer shelf area 1m2 to 50m2 and ice condenser capacity 10L to 500L to select.

Hygienic Drying Process

  • The shelf/tray freeze dryer come with stainless steel drying house, stainless steel door, all internal components that contact product also use stainless steel material. Door seal by medical grade silicone rubber, the inert material no influence dried products quality.
  • Shelves internal are hollow, welding channel enable silicone oil recycle inside bring freezing or heating energy, all the pipes use stainless steel material and go through pressure test, ensure no leakage, no pollute raw material.
  • Drying finish, vacuum break could be pulse air in avoid powder flying in drying chamber, condenser also could install isolation valve and condensing water collect device.


Modular System

  • Commercial and industrial machines are heavy duty and large capacity, many components installed, for easy maintenance and transport, VIKUMER FDL-series freeze dryer are designed by modular: drying chamber, ice condenser, compressor system, vacuum system, medium recycle system etc. scientific installed as module, sensors and electric cables connect electric cabinet, during the freeze drying process, automatic working as per controller directives.
  • Modular system will benefit a lot of its easy transport and install, maintenance, trouble shooting, parts replacement, the system upgrade in future also need less work.


Rich Configurations/Fully Customized

  • According to your special request, budget control, system size or install type, FDL freeze dryer could be flexible design to meet your demand.
  • Parts brand, main material, functions, control type, structure type (vertical or horizontal), all could be customized. please feel free contact VIKUMER to custom your own suitable solutions.
