PLC Control Industrial Low Temperature Lyophilizer Vacuum Freeze
Drying Machine
Product Application:
Vacuum freeze drying also known as lyophilization or freeze drying.
The drying process is by freezing raw product and then move to a
drying chamber, reduce the chamber pressure, enable solid ice
(inside raw product) sublimate to vapor (removed from raw product).
Water removes based on sublimation (Solid to Vapor).
It is composed of a refrigeration system, a vacuum system, a
heating system, and an electrical instrument control system. The
main components are drying box, water trap (cold trap),
refrigeration unit, vacuum pump, heating/cooling device, etc.
Drying Process:
Freeze-drying is a low temperature dehydration process that
involves freezing the product, lowering pressure,removing of ice
(moisture) by sublimation, transitions of the substance from solid
state to vapor without passing through the intermediate liguid
phase. Freeze drying results in a high qualitative product because
the entire process is performed at low temperature and pressure by
applying vacuum, below triple point. The original shape of the
product is maintained and quality of the rehydrated product is
excellent.
Advantages of Vacuum Freeze Drying Machine:
①Keep the food structure, nutritional components and flavor
substances basically unchanged
②The appearance is not dry and cracked, does not shrink, and
maintains the original shape and color of the food
③The product has no surface hardening, and the tissue is porous and
spongy
④Light weight, storage-resistant

FAQ
Q: Can you supply OEM or ODM?
A: Of course we can supply it. We are manufacturer, we can
manufacture the equipments according to your exactly requirements.
Q: Can you help design the entire process line?
A: Of course, our experienced engineers and technicians can help
you arrange the layout and installation of the entire production
line according to the actual situation such as your workshop
layout.
Q: How long is your production cycle?
A: Usually 7-25 working days, the exactly delivery time is
depending on the quantity and your ordering time.
Q: How is the payment?
A: T/T, L/C or other formal import and export payment method.
Q: How long is your warranty period?
A: One year after commissioning is completed.
Q: How to install?
A: Smaller model less than 40KW microwave dryer will be loaded in
full set, so that you can run it only by connect the main power in
your factory. For bigger model, due to the epidemic, we can
currently provide online guidance services by experienced
engineers. If you need on-site installation, we can apply to the
government for installation abroad and calculate all the cost to
customers.
Q: Will you help us if we have any problems in future production?
