PRE-COOLING AND FRESHNESS-PRESERVING COOLING CONTROL DEVICE EMPLOYING DUAL THROTTLING SYSTEMS FOR ICE-CREAM MACHINE, COOLING CONTROL METHOD, AND ICE-CREAM MACHINE

摘要

A cooling control device comprises a compressor, a condenser, a material reservoir evaporator, a freezing cylinder refrigeration inlet conduit, and a freezing cylinder refrigeration outlet conduit. An outlet end of the condenser is connected to a condenser outlet pipe. The condenser outlet pipe is in communication with three branch pipes, which are a freezing cylinder refrigeration pipe, a material reservoir pre-cooling pipe and a material reservoir freshness-preserving pipe arranged in parallel. The freezing cylinder refrigeration pipe is in communication with the freezing cylinder refrigeration inlet conduit. The material reservoir pre-cooling pipe and the material reservoir freshness-preserving pipe are in communication with an inlet end of the material reservoir evaporator. An outlet end of the material reservoir evaporator and the freezing cylinder refrigeration outlet conduit are respectively in communication with the compressor. The cooling control device can separate a pre-cooling mode and a freshness-preserving mode for a material reservoir.
