Problems solved by technology

[0002] The existing freezing control technology includes a drying oven, which is connected to a water catcher through a septum valve, and the water catcher is connected to a vacuum pump and a compressor, which can be used for freeze-drying in the pharmaceutical and food industries. In the future, it is necessary to manually clean the board, box body, and back box. Fully automatic cleaning control cannot be performed, and it cannot meet the needs of more and more manufacturers in the pharmaceutical industry.

Abstract

The invention relates to a full-automatic cleaning control method. The method is characterized in that the method comprises the following steps that: a central control unit is respectively connected with a digital input module, a digital input module and an analog input module, a middle separation valve switching feedback signal and a purge valve switching feedback signal are respectively connected to the digital input module, and a front-box pressure transmitter, a rear box pressure transmitter and a front-box vacuum transmitter are connected to the analog input module; all parameters needed for cleaning control completion are set; and if full-automatic cleaning meets the following conditions that the pressure force is sufficient, the cooling water has a water flow signal, a drying box door is closed, water tank communication is normal and the water tank is not in a local control state, automatic cleaning is started. The provided method has the following advantages: full-automatic cleaning controlling can be realized; the box body can be prevented from being damaged during the cleaning process; and lection button for rear box cleaning selection is added and only the front box and the plate layer are cleaned when the rear box does not need cleaning, so that the demand of the pharmaceutical manufacturer can be well satisfied.

Description

technical field [0001] The invention relates to a fully automatic cleaning control method, which is used for controlling a freeze dryer to automatically complete the cleaning of a plate layer, a box body and a rear box, and belongs to the technical field of freezing control. Background technique [0002] The existing refrigeration control technology includes a drying oven, which is connected to a water catcher through a septum valve, and the water catcher is connected to a vacuum pump and a compressor, which can be used for freeze-drying in the pharmaceutical and food industries. The disadvantage of the existing device is that the medicine is out of the box In the future, it is necessary to manually clean the board layer, box body, and back box. Fully automatic cleaning control cannot be performed, and it cannot meet the needs of more and more manufacturers in the pharmaceutical industry. Contents of the invention [0003] The technical problem to be solved by the inventio...
