During the reaction process of amino acid residues and inorganic salts, the paddles  14  ensure good reaction effect. 
     One end of each paddle  14  is provided with a stirring plate  141 ; an included angle of 45 degrees is formed between the stirring plate and a distance between a free end of the stirring plate and an axis of the rotation shaft to strengthen the reaction effect and hence facilitating production. 
     An upper side of the paddle drying reaction kettle  11  is provided with a material feeding opening  111 ; a material feeding funnel  5  is provided on the material feeding opening  111 , and a first protective cover is further mounted on an upper side of the material feeding funnel  5  to facilitate material feeding and present the waste of raw material.

     Another end of the gas discharging pipe  18  is connected with the vacuum pump  3 . By using the vacuum pump  3 , the paddle drying reaction kettle  11  under a drying function mode will have negative pressure so that the boiling point of water is reduced, and hence drying and evaporation can be performed under a relatively lower temperature. Drying under a reduced temperature can save energy and protect some metal elements which are more active in terms of chemical valency, such as iron. 
     A middle part of the gas discharging pipe  18  is connected with the wet-type dust collector  2 ; the wet-type dust collector  2  comprises a first wet filter tank  21  and a second filter tank  22 .

     As said, 50% of the volume of the first wet filter tank  21  is initially filled with water to collect dust and to absorb a small amount of ammonia; during operation, water evaporated from the paddle drying reaction kettle  11  containing a small amount of ammonia also enters the first wet filter tank  21  via the gas discharging pipe  18 ; when level of water containing collected dust and absorbed ammonia inside the first wet filter tank  21  has reached a pre-determined position, the water from the first wet filter tank containing collected dust and absorbed ammonia is transferred back again into the paddle drying reaction kettle  11 ; part of water vapor resulted after filtration in the first wet filter tank  21  is brought to the second filter tank  22  and condensed into condensate water in the second filter tank  22 , and the condensate water is discharged through the condensate water outlet opening  221  so that water will not enter the ozone generator  4 . 
     An outer wall of the first wet filter tank  21  is provided with a second observation transparent window  211  made of transparent material. Through the second observation transparent window, water level inside the first wet filter tank  21  can be conveniently observed. 
     A circulation pipe  23  is provided with one end connected to the first wet filter tank  21  and another end connected to the paddle drying reaction kettle  11 ; an electronic valve  231  is provided on the circulation pipe  23 ; when the level of water containing collected dust and absorbed ammonia inside the first wet filter tank has reached the pre-determined position, the electronic valve is activated to open so as to allow the water from the first wet filter tank containing collected dust and absorbed ammonia to transfer back again into the paddle drying reaction kettle via the circulation pipe. 
     A control panel  6  is provided on an outer wall of the first wet filter tank  21 ; an electronic liquid level meter  212  is provided inside the first wet filter tank  21 ; the control panel  6  is connected in series with the electronic liquid level meter  212  and the electronic valve  231  for timely alert and control to prevent water level from becoming too high; specifically, when the electronic liquid level meter  212  detects that the water level has reached the pre-determined position, the control panel  6  is activated to open the electronic valve  231  so as to allow the water containing collected dust and absorbed ammonia from the first wet filter tank  21  to transfer back again into the paddle drying reaction kettle  11  via the circulation pipe. 
     An end of the vacuum pump  3  opposite to an end of which connecting to the gas discharging pipe  18  is connected with the ozone generator  4 ; an end of one side of the ozone generator  4  is provided with a chimney  41 ; the ozone generator  4  achieves oxidoreduction of ammonia produced throughout the entire production process, wherein the oxidoreduction reaction is as follows: NH 3 +O 3 =N 2 +O 2 +H 2 O; therefore, ammonia, when reacted with ozone, is transformed into non-toxic gases which are colorless and odorless, and these non-toxic gases are discharged through the chimney  41  high up into the air.
