Food Freeze Dryer
Product description of Freeze Dryer
Food Freeze Dryer is a stable process of drying materials. It first freezes the water-containing materials into solids, and then sublimates the water from the solids to the air, and removes the water to preserve the materials in the solution stage. After freezing, the solvent is reduced to a certain extent, thereby preventing the formation of microorganisms or the chemical reaction between the solute and the solvent, so that the product can be stored for a long time and its properties can be maintained.
The Food Freeze Dryer method is a liquid solid gaseous process. During the freeze-drying process, the liquid bridges between the solution particles have been frozen into solid bridges. The relative position of the particles has been fixed, and there is no surface tension on the gas-liquid interface between the two particles. With the continuous distillation of the solvent, the solid bridges continue to decrease, but the relative position between the two particles will not change until the solid bridges disappear completely.
Machine Parts:
1.Compressor
The Refrigerating System of vacuum freeze dryer adopts the weni-closed compressor imported from USA. The key components such as the medium refrigerator, solenoid valve, expansion valve and oil distributor are also purchased from world-famous companies. Therefore, an ideal refrigerating temperature can be ensured and the reliability product in china.
2.Ammonia System
Ammonia separator system is a unique part of TJL series plants.It consists of ammonia separator,ammonia pumps,vapor trap vessel,pipes and vavles etc.Low temperature ammonia in the separator can keep the vacuum of the cabin for 3 to 5 minutes when temporary trouble occurs.
3.Heating System
Heat supply system-made up of water heating tank,plate exchanger,pneumatic control valves,pumps and pipes, liquid-level indicator, temperature sensors and assembly heating plates,is a forced circulation under the auto-control pressure of gas nitrogen.
4.PLC Control System
MCGS,Delta PLC Show working status, curve,temp.pressure Weighing function and curve Alarm and setting directly Able to exchange different language.
