The present invention relates to a flake-type calcium chloride drying apparatus for liquid calcium chloride using a shell as a starting material and a method for manufacturing a flake-type calcium chloride using the same, wherein the liquid calcium chloride is dried on the surface of a rotating drying drum and the width and length are within a certain range. By manufacturing flake-type calcium chloride that satisfies the requirements, it is possible to improve productivity and use it as a deicing agent without a separate process, and also aims to contribute to resource recycling and prevent environmental pollution by using shells, which are wastes. The flake-type calcium chloride drying apparatus for liquid calcium chloride using a shell as a starting material according to the present invention comprises: first and second rotary drying drums 20 and 30 arranged in parallel with each other; a sprayer 40 receiving liquid calcium chloride and spraying it on the surfaces of the first and second drying drums from an upper portion between the first and second drying drums; first and second heat generators (21, 31) for heating the surfaces of the first and second drying drums to phase-change the liquid calcium chloride sprayed onto the surfaces of the first and second drying drums into a solid through drying; It is installed on the periphery of the first and second drying drums, and includes first and second scraper cutters 50 and 60 for cutting solid calcium chloride transferred along the surface of the first and second drying drums into flake-type calcium chloride. do. According to the present invention, there is provided a method for producing flake-type calcium chloride of liquid calcium chloride using shell as a starting material, comprising: a first step of pulverizing oyster shells; a second step of mixing and dissolving oyster shell powder pulverized in the first step with chlorine (dilute solution) to prepare liquid calcium chloride; a third step of recovering and removing the gas generated during dissolution in the second step; a fourth step of filtering impurities contained in the liquid calcium chloride prepared through the third step; A fifth step of supplying the liquid calcium chloride that has passed the fourth step to a flake-type calcium chloride drying apparatus of liquid calcium chloride using a shell as a starting material to produce a flake-type calcium chloride having a horizontal and vertical width satisfying a certain range .
