[0143] The preparation method of the non-gelatin enteric hard capsule shell of the present invention can be carried out on the existing equipment for preparing the gelatin hard capsule shell. Under the condition that no additional equipment is required, the required non-gelatin enteric-coated hard capsule shell can be produced by adjusting the parameters such as drying temperature, humidity, coating film thickness, operating speed, and mold size according to the formula.
[0144] Compared with the prior art, the main advantages of the present invention are:
[0145] (1) The colloid material used in the preparation of the enteric-coated capsule shell is mainly hydrophilic non-gelatin colloid, and does not contain animal protein and fat, thereby avoiding possible pollution caused by animal protein.
[0146] (2) Optionally add plasticizers listed in the present invention.
[0147] (3) The hydrophilic non-gelatin gel is easy to dissolve, which can save the necessary water absorpt...
