Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil processing, in particular to an automatic temperature control oil preparation, conveying and circulating device. BACKGROUND

[0002] Oil is an important raw material in food processing, also known as plastic oil, which refers to oil that remains solid after solidification. Oil can be melted at high temperature, but will eventually return to solid state at room temperature. For example, butter is a natural dairy product, which is generally referred to as cream extracted from sweet milk, which will become soft at about 15℃ and will melt at 29℃. Therefore, in the process of food processing, oil is heated above its melting point to change from solid to liquid.

[0003] In the process of food processing, the oil circulating system conveys the oil in the oil storage tank to the oil using equipment or oil receiving container. Specifically, the oil circulates in the system: after the oil is output from the oil storage tank, part of the oil flows out from the oil outlet and flows to the oil using equipment or oil receiving container, and the remaining oil circulates back to the oil storage tank. During the flow of oil in the pipeline, the oil is indirectly contacted with the outside through the pipeline, and the temperature of the oil will gradually dissipate and decrease, so that the oil in the pipeline may solidify during the backflow process. The solidified oil not only causes pipeline blockage, but also wastes heat energy for re-melting, which not only wastes resources and increases energy consumption, but also increases production cost and reduces production efficiency. SUMMARY

[0004] The present application aims to provide an automatic temperature control oil preparation, conveying and circulating device to solve the problems in the prior art, which can ensure the circulation efficiency of oil in the production system, avoid the blockage of the pipeline caused by oil solidification, and monitor and control the oil temperature in real time to achieve stable control of the oil temperature.

[0080] (3) The oil storage tank 3 is connected with the hot water tank 8 and the cold water pipeline 10, respectively, so that the oil temperature in the oil storage tank 3 can be adjusted by adjusting the water temperature, and when the oil is output from the oil storage tank 3 through the oil conveying pipeline 4, it first passes through the plate heat exchanger 6, which can quickly reduce or increase the oil temperature through the high-efficiency heat exchange efficiency of the plate heat exchanger 6, thereby preventing pipeline blockage caused by oil solidification due to low oil temperature or production safety hazards that may be caused by overheated oil;

[0081] (4) The hot water in the emulsification tank 2, the oil storage tank 3, and the temperature control pipeline 7 can be returned to the hot water tank 8 for reheating, which can save heat energy;

[0082] (5) The output of the oil outlet branch pipe 41 can be controlled by the first valve 42, which can meet the needs of multiple uses.

[0083] The above embodiments and drawings do not limit the product form and style of the present application, and any appropriate changes or modifications made by those skilled in the art shall be considered as not departing from the scope of the present application.
