Abstract
A method and apparatus for converting gel-like substances from a gel state to a sol state in which the melting speed can be accurately controlled over a wide range and the apparatus can be easily cleaned. A grid-type heater constructed of rotatable parallel heating pipes is disposed at the bottom of a melting tank. Rotation of the pipes which simultaneously heating them imparts flowability to a heat transfer boundary formed on the side of the gel-like substance. The melting speed is controlled by controlling the speed of rotation of the pipes.
