The invention discloses a uniform heat conduction system for a jelly sealing machine and a temperature control method. The uniform heat conduction system comprises a fixing frame. A conveying belt isfixedly arranged on one side of the fixing frame. The edge portion of the top end of the fixing frame is provided with a shell placing block. A feeding groove is formed in a position, corresponding toone side of the shell placing block, of the top end of the fixing frame. The edge portion of top end of the fixing frame is provided with a sealing block. A heat conducting mechanism is fixedly arranged at the bottom end of the sealing block and comprises a hydraulic cylinder, a pressing plate, an oil outlet pipe, an oil via pipe, an oil pump, a through pipe, an oil pipe and a filtering box. According to the uniform heat conduction system for the jelly sealing machine and the temperature control method, through cooperation of the heat conducting mechanism, a cleaning mechanism, a dustproof mechanism and an energy-saving mechanism, optimization is conducted on the pressing plate and pressing block uniform heat conducting process, the heat recycling process and the sterilization process; and meanwhile, through a material collecting mechanism, the difficulty of collecting jelly products by workers is reduced, the sealing efficiency of the jelly sealing machine is effectively improved, and the jelly sealing machine is more efficient and energy-saving.
