The invention relates to a carragheenan and 
potassium chloride gelled hydroxypropyl methylcellulose enteric-coated hollow 
capsule, and belongs to the technical field of the production of hollow capsules. The hollow 
capsule is characterized in that the hollow 
capsule is prepared through mixing a main 
raw material hydroxypropyl methylcellulose with carragheenan and 
potassium chloride under a special condition, the hollow capsule has the characteristics of timely disintegration, low 
water content, suitableness for medicines having strong hygroscopic property and being sensitive to water, small influences of a dissolve-out medium to the shell of the capsule, high 
drug compliance, long storage duration data, no deterioration within 3-4 years, low condition requirements on the storage and the transportation, difficult crushing in the low 
humidity environment, difficult deformation, 
putrefaction and deterioration in the high temperature environment, according with the requirements of populations having all culture backgrounds because of pure 
vegetable fibers, almost no 
pollution in the production process, secondary re-dissolving utilization of 
tailings, omission of the commonly-used surfactants and plasticizers, acceleration of the gelling speed by reducing the gelling temperature only through utilizing 
potassium chloride to assist the carragheenan, additive reduction, production cost reduction, and suitableness for the 
mass popularization.
