Dry dual radiation plate of vacuum freezing

The utility model belongs to the technical field of freeze-drying equipment technique and specifically relates to a dry dual radiation plate of vacuum freezing, including refrigeration evaporation pipeline and distillation water back, refrigeration evaporation pipeline and distillation water back by a plurality of mutually parallel and equally spaced vacuum pipe arrange into a plane, refrigeration evaporation pipeline is established on the distillation water back, links to each other through the pipe between the vacuum tube, wholly being the form that spirals and connecting, the refrigeration evaporation pipeline upper left corner and the upper right corner are equipped with refrigeration return-air mouth and refrigeration feed liquid inlet respectively, distillation the water back lower left corner and the lower right corner are equipped with respectively heat back liquid mouth and heating feed liquid inlet, refrigeration evaporation pipeline has the radiation plate with the outside package of distillation water back, the radiation plate right side is equipped with the installation guide rail this device has reduced the cost of labor, has reduced investment cost, reduces the energy consumption and more than 30%, has shortened drying time
