A thermostat device for a chocolate manufacturing device, comprising a base, a transparent outer casing, and a thermostatic module. The outer casing is mounted above the base and includes a casing body and a door panel that is openably coupled to the casing body. The housing cooperates with the base to define an accommodation space suitable for the chocolate manufacturing equipment to be placed, the accommodation space being constant temperature and capable of being kept sealed. The thermostatic module is installed in the base and can generate cold air to maintain the accommodation space at a constant temperature. The thermostat module enables the chocolate to maintain a constant temperature at a low temperature after the manufacturing process and the manufacturing process, so that the chocolate is of good quality and easy to shape. The structure and transparent design of the shell allow the chocolate manufacturing process to be viewed, making the people feel new and interesting and add fun.一種巧克力製造設備的恆溫裝置，包含一底座、一透明的外殼，及一恆溫模組。該外殼安裝在該底座上方，並包括一殼本體，以及一可開啟地結合在該殼本體上的門板。該外殼與該底座配合界定出一適用於供該巧克力製造設備擺放的容置空間，該容置空間為恆溫且能保持密閉。該恆溫模組安裝在該底座中，並能產生冷氣以使該容置空間維持恆溫。藉由該恆溫模組使巧克力在製造過程與製造完成後都能保持低溫之恆溫，使巧克力品質佳、容易定形。該外殼之結構與透明設計，讓巧克力製造過程可供觀賞，使民眾覺得新奇有趣，可增添樂趣。
