The invention discloses a 
laundry detergent and a preparation 
system and a preparation process thereof. The 
laundry detergent comprises the following raw materials (by weight): 5 parts of 
sodium fattyacid methyl 
ester sulfonate, 21 parts of 
sodium lauroyl sarcosinate, 5 parts of 
decyl glucoside, 4 parts of cocamidopropyl hydroxysulfobetaine, 8 parts of imidazoline amphoteric disodium diacetate, 1.5 parts of 
protease, 0.6 part of 
cellulase, 0.9 part of 
xanthan gum, 0.6 part of 
sodium hydroxymethylglycinate, 0.5 part of 
borax and 10-20 parts of deionized water. The process comprises the following steps: 1, putting the 
laundry detergent to be processed into a stirring box body, and pouring an enough defoaming agent into a defoaming agent pouring mechanism; 2, starting a stirring 
assembly andthen evenly stirring and mixing the 
laundry detergent in the stirring box body, and simultaneously conducting physical defoaming; 3, pouring the defoaming agent in the defoaming agent pouring mechanism into the stirring box body when the foam amount is continuously increased, and carrying out chemical defoaming; 4, enabling the stirring 
assembly to work to uniformly mix the defoaming agent and the 
laundry detergent until the defoaming agent fully reacts; and 5, discharging the stirred and mixed 
laundry detergent out of the stirring box body.
