at present, only one set of drainage separator (connected with an automatic drainer) is arranged at the outlet end of an evaporator and before entering a precooler, so that a small part of water cannot be completely settled under a critical state, and the water content of rear compressed air is increased.

Disclosure of Invention

An object of the utility model is to provide a freezing formula desiccator evaporator structure to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a freeze dryer evaporator structure comprising: the pre-cooler shell is a sealed shell, the upper end surface of the pre-cooler shell is respectively provided with an air inlet pipe and an air outlet pipe, the lower end surface of the pre-cooler shell is respectively connected with the upper end surface of the evaporator shell through a connecting outlet pipe and a connecting inlet pipe, the evaporator shell is a sealed shell, the pre-cooling heat exchange pipe is arranged in the pre-cooler shell, one end of the pre-cooling heat exchange pipe is connected with the connecting inlet pipe, the other end of the pre-cooling heat exchange pipe is connected with the air outlet pipe, the refrigerant heat exchange pipe is arranged in the evaporator shell, two ends of the refrigerant heat exchange pipe extend out of the evaporator shell and are communicated with a compressor system, the drainage separator is arranged on the rear side of the lower end surface of the evaporator shell, and the automatic drainage device is arranged at the lower end of the drainage separator, the water-blocking plate is arranged at the rear side in the evaporator shell and is positioned above the drainage separator.

Furthermore, rubber heat-insulating cotton is wrapped outside the precooler shell and the evaporator shell.

Furthermore, air guide clapboards are arranged in the precooler shell and the evaporator shell and can be used for water to pass through.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a freezing dryer evaporator structure makes the improvement on prior art's basis, sets up the board that blocks water at the inside rear side of evaporator shell, before the gas after the heat transfer gets into the drainage separator, a large amount of compressed air or the gas of taking a small amount of moisture can collide on the board that blocks water to separate water and gas, water sinks into the drainage separator under the action of gravity, and dry gas then rises and gets into the rear end filter, reaches the extremely effect that sends cooling drying.

The utility model has the advantages of simple structure, convenient production, good use effect, etc.
