KEMOLO FD-500 Freeze Drying Machine

Freeze drying machine, known as lyophilizer, working principle is ice sublimation. FD-500 freeze-drying machine is the smallest radiant freeze-dryer with blast freezer, rail system and trolleys. The FD-500 freeze drying machine is a separated structure. The chamber is one individual unit, and refrigeration, vacuum and heating systems are assembled in another unit. Blast freezer (IQF) is a separated unit used for quickly freezing products to -35°C becoming ice. And the ice is sublimated into vapor and removed out of the product, collected on a low temperature vapor condenser inside the freeze-drying machine. The product is dried 100% natural, without shape changing, color changing, nutrition lost, flavor lost, longer shelf time without additives and preservatives. The FD-500 industrial freeze-drying machine is widely used in food industry to freeze dry fruits, vegetables, plants, meat, sea food, cooked food, milk, coffee, pet food etc.

The principle and process of freeze-drying
The principle of freeze-drying is to remove water by sublimation and collect by condensation. The freeze-drying process is divided into three stages: (Product freezing stage, primary lyophilization stage; secondary lyophilization stage,<1% water remained)

Advantages and applications of freeze-drying
Freeze-dried products are 100% natural, without additives and preservatives, and can be stored for up to 25 years without changes in color, shape, flavor and nutrient. KEMOLO freeze dryer is mainly used in the food, biological, dairy, nutraceuticals and pet food industries.
12 to 18 hours Fast Freeze Dry
The fresh product is pre-frozen to -35°C in an individual quick freezer before entering freeze dryer. High heat transfer coefficient heating plates (thermal property: 160W/m-K) are used to speed up freeze drying process. The efficiency of thermal is 11.42 times higher than traditional freeze dryers. To finish a batch of production, it takes 12-18 hours only for many kinds of food.

30-50% Energy Saving
Freeze-dry consumes a lot of power. To save energy, solar heating and steam is introduced to large scale freeze-dry system. The heat from refrigeration system is recycling, and the working load of compressor is reduced to 75-50% load at the middle and late stage of freeze dry, adjusted automatically according required cooling capacity. Ice on the vapor condenser could be recycled and filtered for re-use. By shorten the freeze-drying time and introducing energy saving technology, the KEMOLO freeze dryers could save 30-50% energy compared with traditional dryers.

Environment friendly
The freeze-drying machine provided by KEMOLO is suitable for environmentally friendly refrigerants and is filled at the user's site. It has no harmful to ozone. It is approved in any countries. The freeze-drying plant is separated into clean room and equipment room, so as to isolate noise, smog and dust pollution to food.

Equipment Safety
The KEMOLO vacuum freeze-drying machines are with all necessary protections. The users are free from any risks of explosion, combustion and electric shock.

User-friendly design
Scientific and reasonable workshop layout; The height of equipment is easy for people to operate; 4 languages in touch screen and showing at any page, the operators would never lose themselves at a foreign language page; 2 touch screens optional (1 touch screen near the door, and 1 touch screen on the control box). It is convenient in use. And system can be run automatically.

4G/WiFi monitor and control
KEMOLO freeze drying machines could be monitored and controlled by remote PC or mobile phone App through 4G, WiFi or internet wire.
