Description

Technical Field

[0001] The utility model relates to the technical field of food, fruit and vegetable cooling devices, and more specifically to a steamer system with both steaming and cooling functions. Background Art

[0002] The current production process of quick-frozen corn cobs: peeling fresh corn cobs → cutting tips and stems → cleaning → steaming in a pressure cooker → cooling in a 35℃ room temperature water pool → cooling in a 5℃ ice water pool → -10℃ pre-cooling tunnel → -35℃ quick-freezing tunnel → packaging and warehousing (-18℃ refrigerated storage).

[0003] On the one hand, there are many process steps, and there is currently no integrated device that has both steaming and cooling and dehydration functions, which makes the operation complicated; on the other hand, the corn cobs are dehydrated in the production process, but the current dehydration effect is not good. Even the advanced vacuum dehydration method has shortcomings, mainly manifested in that the excluded water absorbs the heat of vaporization, causing the remaining water to cool down until it freezes, and the remaining water can only be slowly discharged in the form of sublimation, which prolongs the vacuum dehydration time, resulting in reduced quality of dehydrated vegetables and increased dehydration costs.

[0004] Therefore, providing a steamer system with both cooking and cooling functions is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the utility model provides a steamer system with both cooking and cooling functions, which increases the steamer function, simplifies the quick freezing process, and adopts a combination of exhaust, water spraying and vacuum to achieve cooling and dehydration of corn cobs before quick freezing, thereby ensuring the dehydration effect.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A steamer system with both steaming and cooling functions, comprising:

[0008] A steamer, wherein the steamer is connected to a high-temperature steam pipeline, a first solenoid valve is installed on the high-temperature steam pipeline; a second solenoid valve is installed on the exhaust pipeline of the steamer; and a third solenoid valve is installed on the drainage pipeline of the steamer;

[0009] A spray cooling system, the spray cooling system comprising a pure water container and a first pipeline, the pure water container is connected to the steamer through the first pipeline, and a spray water pump and a water spray solenoid valve are sequentially installed on the first pipeline;

[0010] A vacuum cooling system, the vacuum cooling system includes a vacuum solenoid valve, a cooling water heat exchanger, a steam-water separator, a water trap, a Roots vacuum pump and a water ring vacuum pump which are connected in sequence through a second pipeline, the Roots vacuum pump is connected in parallel with a bypass solenoid valve through a bypass pipeline; a fourth solenoid valve is installed on the drainage pipeline of the steam-water separator; and a fifth solenoid valve is installed on the drainage pipeline of the water trap.

[0011] By adopting the above scheme, the beneficial effects of the utility model are:

[0012] 1) The steamer, spray cooling and vacuum pre-cooling system are integrated to realize the steamer and vacuum cooling and dehydration functions, increase the steamer function, reduce the production cost and simplify the quick freezing process;

[0013] 2) The cooling process of the corn cobs after cooking is decomposed into three stages: exhaust cooling, water spray cooling, and vacuum cooling to ensure the dehydration effect;

[0014] 3) The cooling water heat exchanger and water trap partially cool and condense the steam before it enters the Roots vacuum pump and the water ring vacuum pump, reducing the volume flow of steam entering the Roots vacuum pump and the water ring vacuum pump, thereby improving the steam extraction efficiency of the vacuum pump and reducing the purchase cost of the vacuum pump.
