Problems solved by technology
[0002] Generally, the common ice cream mixing devices on the market use a set of refrigeration system to cool down the mixing drum containing the ice cream raw materials, and continuously stir the ice cream raw materials in a low temperature environment to produce ice cream. Before freezing the ice cream raw materials, another heating device is used to It is sterilized, because there is a process of transferring raw materials between two equipments, it is inevitable that the raw materials will be contaminated again during the transfer process, and because two sets of equipment are required to work alternately, the production cycle will be prolonged and the production cost will be increased. Necessary to improve

The invention relates to an ice cream stirring apparatus with heating and refrigeration functions, belonging to the food processing machinery; the ice cream stirring apparatus comprises a compressor, a condenser, an evaporator, a mixing drum, a heat exchange cylinder, an electric heater and an oil pump; the evaporator and the electric heater are arranged in the heat exchange cylinder, conduction oil is arranged in the heat exchange cylinder, after a conduction oil outlet of the heat exchange cylinder is serially connected with the oil pump and a solenoid valve, and then the conduction oil outlet of the heat exchange cylinder is connected to a working medium inlet of the mixing drum, and a conduction oil inlet of the heat exchange cylinder is connected to a working medium outlet of the mixing drum; in the invention, a material storage cylinder is arranged in front of the mixing drum; the conduction oil is used as heat transfer working medium among the heat exchange cylinder, the mixingdrum and the material storage cylinder, when the temperature of the conduction oil is raised, the ice cream raw material is sterilized at high temperature; when the temperature of the conduction oil is reduced, the ice cream raw material in the mixing drum is stirred in a freezing way, pre-cooling is carried out to the material storage cylinder, so as to lead the ice cream raw material to be manufactured into finished products without transferring between two sets of the equipment, and the ice cream stirring apparatus has the advantages of sanitation and safety and simple operation, the ice cream stirring apparatus is suitable for various ice cream machines and can be used for a snow melting machine and an ice water machine.
Description
technical field [0001] The invention belongs to food processing machinery, in particular to an ice cream machine with pasteurization function. Background technique [0002] Generally, the common ice cream mixing devices on the market use a set of refrigeration system to cool down the mixing drum containing the ice cream raw materials, continuously stir the ice cream raw materials in a low temperature environment to produce ice cream, and use another heating device to cool the ice cream raw materials before freezing the ice cream raw materials. It is sterilized, because there is a process of transferring raw materials between two equipments, it is inevitable that the raw materials will be contaminated again during the transfer process, and because two sets of equipment are required to work alternately, the production cycle will be prolonged and the production cost will be increased. Improvements are necessary. Contents of the invention [0003] The object of the present in...
