Under vacuum condition, material is freeze dried via principle of sublimation. The moisture in the pre-frozen material is directly sublimed from solid state (ice) to gaseous state (vapor), without melting. Freeze dried products are formed to be sponginess, without shrinkage and excellent in rehydration, containing little water only. The freeze dried product in sealed packaging can be stored and transported at room temperature for a long time.

Features & Advantage
1.Much lower frying temperatures (approx. 90 to 120℃ in practical operation, depending on the product) to maintain flavours and colors
2.Processing products with higher reducing sugar levels in comparison with normal atmospheric conditions
3.Minimizing of health harmful thermal reaction products, such as acrylamide
4.Texture can truly be influenced
5.Evaporation rate will be faster
6.Pressure as a new parameter of control next to retention time and temperature
7.More gentle oil handling
8.Lower steam pressure for frying oil heating systems required than in atmospheric fryers (approx. 8 bar)
9.No frying vapor emission
Training plan: We will provide training for those who operate and maintain the freeze-drying machines. Trained by supplier of the equipment in the process of installation and debugging, people can operate and solve the basic mechnical problems independently. In addition, the persons who work in general engineering such as refrigeration, boiler, and transformer substation shall be undertaken by skilled workers.
1. We guarantee that the commodity hereof is made of the best materials and new brand with top workmanship, and in accordance with quality specification stipulated in product Contract and Appendix.
2. Guarantee period shall be within 12 months from the date of acceptance. During this period, if there are quality problems, we will provide solution by verbal or written communication. If the problem is unsolved, our engineers will repair for you on site as soon as possible. The maintenance is free when there are non-operation errors; otherwise it is for the buyer’s account.
