Detailed Description
The following describes embodiments of the present invention in detail with reference to the accompanying drawings.
When the ultrasonic-assisted freezing equipment is used for freezing products, the food is generally not directly placed in the groove of the ultrasonic-assisted freezing equipment because the convection heat transfer coefficient of air is low, and in order to increase the heat transfer coefficient with the food, some liquid is often used as a heat transfer medium in the middle, such as calcium chloride solution.
Before preparing the ultrasonic-assisted freezing, the vortex tube 9 is firstly opened for temperature regulation, and the air flow can be regulated by regulating a regulating valve at the air inlet of the vortex tube 9. When the temperature inside the equipment box body 1 reaches the set temperature and the temperature is constant, the calcium chloride solution is placed into the equipment box body 1 for precooling, the temperature of the calcium chloride solution is monitored, when the temperature is consistent with the initial temperature of required food, the food is placed into the calcium chloride solution, because the density of general food is smaller than that of the calcium chloride solution, when the amount of the food placed into the equipment box body reaches a certain limit, the hydraulic telescopic column 3 is opened, the mesh enclosure 4 is driven to press the food into the calcium chloride solution, the food is completely immersed into the calcium chloride solution, and the heat conductivity coefficient of the food is increased. At this time, the required ultrasonic frequency is started, and three frequencies can be started simultaneously. Finally, the circulating water pump 14 is started, so that the salt solution in the equipment box body 1 is in a fast flowing state, the internal temperature field is uniform, and the purpose of freezing food with high quality is achieved.
The method comprises the following specific implementation steps:
preparing a calcium chloride solution, and injecting the solution into the equipment box;
starting an air compressor, and starting a vortex tube auxiliary refrigerating device;
putting frozen food to be frozen into calcium chloride solution, and pressing the food into the solution by using a mesh enclosure;
starting a circulating water pump to enable the calcium chloride solution in the inner box body to be in a flowing state;
starting the ultrasonic wave generating device, wherein the required frequency of 0-20KHz, 20-40Hz and 40-60Hz can be selected and started according to the requirement;
monitoring the temperature of the calcium chloride solution in real time, and controlling the flow by adjusting a hot end valve of the vortex tube so as to adjust the temperature of the calcium chloride solution;
after freezing, the mesh enclosure is lifted and the frozen food is taken out.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the utility model. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
